Liquid wood has many advantages. Let's talk about what it consists of where it can be used to pay attention to when buying this material, as well as how to make it yourself.

What is the liquid wood

Of course, the real tree cannot be liquid. Such a phrase refers to a wood-polymer composite (DPK) - new construction materialwhich includes the following components:

• grinding wood base (sawdust, chips and other),
• binder part (polyethylene, polypropylene and so on)
• additives (additives).

Moreover, the tree itself in the DPK may be contained up to 80 percent. And this is not freshly edged material, but waste from the production of sawn timber. That is, in the production of DPK, not a single tree was actually injured.

The strength of products from liquid wood sometimes exceeds even the indicators of the glued timber. After all, thermoplastic polymers, sintering particles of sawdust and chips in the monolithic mass act as a bundle in the manufacturing process.

Well, the most interesting component, this alloy is additive additives. It is they who protect the wood base from fungus, mold and moisture. It is they paint products into a pleasant "woody" color. And additives allow you to interfere with DPK, resulting in an easy, but durable mass.

To mix all components, manufacturers of DPK need only to heat the composition before the ignition and provoke the joint polymerization effect. After that, the hot mass is poured into the form. And after the cooling of this casting, in the process of which forced cooling is allowed, we get a finished product - ancientifer.

Where you can use the DPK

The ancalter has the properties of natural and man-made materials. It looks and smells like a tree and does not rot, does not react to temperature fluctuations and does not destroy under the action of ultraviolet as plastic.

Products obtained from antipaths found their use in construction, and in design. From the DPK make the excellent basis for the floor. Even open terrace can be used by boards made of liquid wood. And they will not breed or crack from the cold and rot from rain or snow. And from the apertol, you can cast blanks or parts for furnishing items. And they will keep the load better wood stoves.

In addition, elements of the external and internal decor are made from DPK. Addivities do not affect environmental friendliness, polyethylene uses even the food industry, and the tree is the most favorable option for human health from all building materials. Therefore, the DPK finishes will be more appropriate than plastic panels or vinyl wallpapers. Although this option will require good ventilation of the decoration of the orphanage.

In addition, this material is badly burning and tolerates the neighborhood with brick or concrete. Where the tree begins to pull moisture and rot, the DPK lies and does its job for 40-50 years. That is why the anteroplast is a very promising finishing material for external work.

In a word, a natural tree has only one indisputable advantage over a liquid analogue - low cost. Boards and DPK products are a bit more expensive than materials made of natural wood. However, taking into account the fact that lumber with similar durability and durability can only be obtained from valuable wood species, the difference in price does not look so stunning, as it would seem.

How to make DPK do it yourself

For this you need to take the following:

1. 1. Take wood sawdust. Moreover, the basics are not important here - you can also take a pine and oak chips.
2. 2. Fall asleep chopped wood into the coffee grinder (desirable electrical) and grind it on the "flour".
3. 3. Prepare a stirring container. It may be a pelvis, and a bucket, and a small bank.
4. 4. Purplify wood "flour" into the container and pour it with a PVA glue. Moreover, if you need high strength - use non-stationery, and building formulations or carpentry adhesives based on them.
5. 5. Beat the mass using a mixer to a homogeneous consistency. With large volumes it can be a building mixer.

If the composition is too liquid - you need to add sawdust. If you got a very thick mass - PVA adhesion.

True, according to the above recipe, you will succeed in not full of anticipate, and its analogue. But according to the structure and basic qualities, the homemade material will almost not differ from the factory. It can be used to close the holes, cools and other defects in the present DPK, as well as for casting decorative elements that do not carry the operational load.

With the sealing of defects, the following technology is applied: the following technology is applied: they are applied to the place of damage and fill the chip or hole with the resulting mass using a rubber spatula for grouting the seams in the tile. After frozen, the residues of the mass are primed with fine-grained sandpaper and painted under the color of the surface.

For the fill of the homemade DPK, a liquid composition resembling a solution of concrete is used in the form. And to extrude bubbles from castings, the filled form passes the vibrationandend. After that, it is left alone until complete drying. Small defects on the surface of the casting can be filled with glue or shrink.

Inspect the board or other product from liquid wood. If there are light dots on its surface, then you have a product of dubious quality, since such a defect signals about poor-quality grinding and kneading flour. Under the open sky, such a product will not live for a long time. The dots will begin to black, attracting rot and moisture, after several years of operation.

Pay attention to the texture of the product. For decoration, it is often preferred to take a smooth, almost polished surface. For floor covering, smooth boards cannot be used in any case, they are very attendable. It is best to take a grungy version, even with applied rifer.

If possible, find out the composition of wood flour used in the production of DPK. The best way - Waste wood hardwood. Such materials are badly burning. But smiling coniferous breeds Loop the fire safety of your home at once a few points.

Look at the color of the product. It should be uniform. Spots, bright areas and other defects talk about the poor kneading components. Such a board and looks bad, and inferior in strength even ordinary wood, not to mention high-quality DPK.

Find out what warranty obligations are provided. Reliable manufacturers give a warranty for 20-25 years. If we are talking about 4-5 years to the board, then there are obvious miscalculations in such ancolor. Try to abandon such a purchase.

If you follow these tips, the purchased DPK products will not disappoint you within 30-40 years of service.

The tree is perhaps the most sought-after building and finishing material. The wood is universal in processing, has high thermal insulation and aesthetic qualities, is indispensable when creating unusual architectural buildings, exquisite furniture, decoration of the interior and design of household sections. The only drawback of the tree - susceptibility to unfavorable external factors and the ability to rot.

In an effort to preserve all the advantages of the wood and to reduce all its drawbacks, the manufacturers have created an innovative building material - a wood-polymer composite. Consider what "Polywood" represents which properties, characteristics are inherent modern material, and what is the scope of its application.

Main types of wood composite materials

Wood composites are materials obtained as a result of combining different raw materials. The main component of the wood composite is a tree. The amount of wood waste, as well as the type of binder component, determine the main characteristics of the composite material.

The most common wood composites are:

Polymer composite: Photo Base for Patio from Decing Board

​

Let us dwell in more detail on the composition of the innovative material, the technology of its production and technical and operational characteristics.

Wood-polymer composite: production and composition of material

IN the composition of the DPK. Interest three main components:

1. The chopped wood particles (some manufacturers for cheaper products are added rice husk particles or cake seeds).
2. Thermoplastic polymer (polyvinyl chloride, polyethylene, polypropylene).
3. A complex of modifiers - chemical additives (up to 5% in the composition of the material).

The production of wood-polymer composite occurs according to the scheme.

Grinding wood. The tree is processed on hammer and knife crushers to obtain particles of 0.7-1.5 mm. After crushing, wood is sieved and fractionated.

Of the smallest fractions make a profile without finishing the surface, from the average components - a profile under the trim with veneer, paint or film, and coarse fractions of wood are used to create technical profiles

Drying wood It is carried out if the humidity of the raw material exceeds 15%.

Dosing and mixing components. All components of the DPK are connected in the desired proportions and mixed with each other. Most often, such ratios of components of wood flour / polymer are used:

• 70/30 - in the composite there is a property of wood fibers, as a humidity expansion; DPK is considered more fragile and has a life for about 5-7 years;
• 50/50 - the optimal ratio of wood and polymer, in which the decorative properties of the wood and the strength of the polymer are preserved;
• 40/60 - the aesthetic qualities of wood weaken, the material is felt and looks like plastic.

Pressing and formatting the product. The final stage in which the technical properties of the DPK are formed and the material acquires a commodity appearance.

Technical and operational characteristics of wood-polymer composite

The properties of the composite are determined by the amount of wood in the material, the type of wood used and the polymer. We note the general mechanical and physical indicators of the DPK:

1. Density of material. The indicator depends on the base resin used, the amount of applied additives and the density of wood particles. The maximum DPK density is 1.4 kg / dm3 (true wood density).
2. Extension during tension - 0.5-1%;
3. Bending resistance - 25-60 MPa;
4. Sharpy shock viscosity - 3-4 kJ / m2.

The wood part of the DPK gives the material such properties:

Polymer qualities of DPK are manifested as follows:

Comparative characteristic of wood and DPK

In order to more clearly characterize the wood-polymer composite, we will carry out a comparative analysis of the main qualitative and economic indicators of the tree and the DPK.

Scope of the DPK.

Due to its advantages, the wood composite won wide popularity in the industrial sphere, construction and in everyday life:

Over 50% of the wood-polymer composite is used as "Decing" - wooden boards and tiles for the design of coastal and dissing architecture

Overview of the main manufacturers of DPK boards

Deoping boards from DPK are presented in the construction market by many manufacturers. When choosing a material, it is better to give preference to well-known companies - their product has already passed the test of time on quality and won a positive reputation around the world.

Terraced board Bruggan (Belgium) is made of high-quality raw materials, products are focused on the international market. By textile sensations, the board is as close as possible to the wood.

Bruggan board has the following composition:

• tree - 60%;
• polymers - 30%;
• additives - 10%.

The company produces a hollow and full-fledged terrace board, which is used to arrange the territories around the pools, the creation of terraces, summer sites of hotels, bars, restaurants, stairs buildings.

Full-night terraced board Bruggan Multicolor has the texture of a tree on the thickness of the material, is suitable for grinding and radius trim

Approximate price of Board Bruggan 1000-1200 rubles per profile

Terraced board MirradeX. (Malaysia) is made of tropical trees fibers, which increases the stability of the material to moisturization. The board does not require additional treatments. Board structure - Bilateral - This allows the use of material to create vertical structures (fences, fences).

Mirradex board composition:

• wood - 50%;
• polymer (polypropylene) - 40%;

The Mirradex terrace board refers to the category of premium class materials, but it has a relatively available cost (about 750 rubles per profile).

Terraced board Legro. (Hungary) has a special protective layer, which increases material wear resistance. The Legro board is suitable for the arrangement of terraces and platforms in public places with increased permeability.

Benefits of Legro Board:

• does not fade;
• on the surface there are no stains;
• damage resistance (scratches, dents);
• bilateral unstailed texture.

The composition of the DPK Legro:

• chopped wood - 50%;
• polypropylene - 45%;
• additives - 5%.

You can buy a wood-polymer composite of Legro at a price of 3500 rubles for one profile of 150 * 25 * 5800 mm.

"Liquid Tree": manufacturer and use in everyday life

At home, you can create an analogue of the wood-polymer composite with your own hands. As a result of the work, it turns out the "Liquid Tree", which is suitable for the restoration of furniture from the chipboard, repairing a parquet board and laminate.

The whole process of manufacturing home-made "liquid wood" can be divided into the following steps:

• Wood sawdust to grind with the help of a conventional coffee grinder.
• The resulting flour is connected to PVA glue. The ratio of components: 70% - wood, 30% - glue. Liquid Tree should have a thick consistency.

The resulting paste is applied to the damaged area of \u200b\u200bfurniture or flooring, and is left to full frost (about 4-5 hours). After that, the excess "liquid wood" must be cleared with sandpaper.

To give a "liquid wood" of the desired shade into the mixture, you can add a dye intended for water-level paint

The appearance of wood-polymer composites allowed to combine the most significant advantages of wood and plastic in one material. Constructions and designs from DPK are convenient in installation, have excellent performance and have aesthetically noble appearanceinherent in natural wood products.

From the article you will learn about a completely new material - a wood-polymer composite or DPK. We will talk about production technology, assortment of products and the benefits of each type in front of natural analogues. Also in the article are given useful advice On the selection of a terraced board of DPK.

The last 40 years of industry development can safely be called "era combined materials." Modern equipment and technologies allow you to connect, it would seem incompatible: wood, concrete, plastic, paper, metal. All of them are mixed, diffusively fused with one goal - get a new product combining best properties several source materials. So, among other things, we saw a "liquid tree".

What is a "liquid tree"

Speaking by technical language, this is an extruded wood-polymer composite (DPK). This means that the wood component is canned with plastic. In such a combination, the material takes the best properties:

1. From wood - compressive strength, impact resistance, elasticity. At the same time, the wood component is almost free - any waste, crushed in flour, go into the course.
2. From plastic - corrosion resistance, flexibility, processing accuracy. The polymer envelops wood particles and eliminates the main drawback of the tree - destructive reactions with water. The polymer in this technology is 90% secondary plastic, i.e. recycled waste.

The technological process is easy to understand, but quite complicated for execution. The polymer (plastic) is mixed in a certain proportion with wood flour and heated so that it melted. Then form in extruder, on rollers or in molds and cooled. At various stages, about 10 different additives are mixed into the mass - plasticizers, catalysts, hardensors and others. All the details of the manufacture - the grade of wood and plastic brand, the proportions of the mixture, additives, temperature modesAs a rule, make up a production secrecy. It is known that all ingredients can be purchased in a free sale, and for wood flour, the bamboo, larch and other robust breeds of the average price category are predominantly choose.

For the manufacture of DPK, special multi-stage production lines are created. They consist of a variety of devices and controllers. Collect such a machine with your own hands in the garage, unfortunately, will not work. But you can purchase a ready-made production line.

Products from DPK.

Currently, the product range is incomplete, since the material is relatively new and its properties to the end are not studied. However, several of the most sought-after positions can be mentioned now.

Terraced board or decong

It is up to 70% of all demanded products from DPK today. Most of the supplied production lines are focused on the release of this board, since this is the only alternative to the tree. The board consists of a perimeter frame, the rigid ride inside and has a puzzle fastening system. Different colors are offered.

Benefits Before the traditional material: From the tree, the DPK Board is beneficial to solid processes and the best physical indicators (strength, flexibility, processing accuracy). Many types of DPK boards are produced by bilateral - with the reliefs of the wood array and ribbed cutting.

Facing facade panels or plaquene

By and large, they can be correlated with vinyl siding - the principle of installation and the structure of the panel they are very similar. But the DPK panel is much thicker and tough, respectively, has a greater weight and the best physical properties.

Advantages over traditional material: a more durable and durable facade, sinuses in the panels and thick walls are better kept warm and absorb noise.

Fences, fences, perilla, balustrades

Molds of small architecture from the "Liquid Tree" for the decorative finish of the exterior and landscape. Have a good bearing capacity and suitable for intensive operation (in crowded places).

Such products were made to perform from wood (short-lived and requiring care) or concrete (heavy, cold and not always reliable). Wood-composite forms make national teams, and all the details are designing in advance. There remains on the spot only to assemble them with the help of a grinder and screwdriver. Such a fence does not require a powerful foundation, constant coloring. In case of damage to the site or structure element, it can be easily replaced by making an additional number of parts.

The overall advantage is the absolute insensitivity to atmospheric wear (moisture, frost, overheating in the sun), insect, fungi and abrasion.

The overall drawback is relatively large oscillations when heating and cooling. The expansion of the DPK terrace board can be up to 6 mm per 1 m (with gradual heating to +40 ° C).

Prices for facade panels from Liquid Tree

How to choose a terraced DPK board

Any kind of "liquid wood" is made of wood flour, the composition of which is not so important. But the composition of the polymer, which is added to it may be crucial:

1. Polymer based on polyethylene. Easier and cheaper in production. Contains a greater amount of sawdust, due to which it is cheaper analogs. Prone to UV radiation (without additives).
2. Polymer based on PVC. More resistant to temperature drops, ultraviolet, large fire safety. Durable 2 times compared with other compositions.

By the type of profile, terraced boards are divided into two types:

1. Forty. Consider significant shock loads. It is well suited for places with a large passability - summer cafes and verandas, decks of ships, embankments and piers.
2. Hollow. Have low weight. Suitable for terraces of private houses.

By type of connection board, DPK are divided into:

1. Suture. Mounted with a gap of 3-5 mm and provide a good removal of water. Mashed metal or plastic cleans.
2. Seamless. Create a solid durable surface by mutual clutch. Must with self-drawing, clemmers are not required. Suitable for summer sites of a cafe - small things, heels, etc. do not fall into the gaps, etc.

By type of anti-slip or processing:

1. Treated with brushes ("Brashring" from English. Brush - brush, brush). The surface created by a metal brush (artificial aging).
2. Grinded. The surface is processed by the emery web.
3. Embossed. Typically, executed in the structure of the tree. Good decorative ViewBut in the passable places the drawing is grieving and it becomes noticeable.
4. Co-extrusion. The upper layer is performed from high strength composition and is structured during the extrusion of the board itself.
5. Co-extrusion with deep embossing (from English. EMBOSSING - embossing). Embossing on the upper layer imitates the valuable wood species.

To pay attention regardless of the type of board selected:

1. Height Ryube. It depends on the strength of the board.
2. The number of ribbiness. It affects the flexural strength - than them more, the higher the strength.
3. Wall thickness. Thin walls (2-3 mm) do not keep loading loads.
4. Width of the board. The wider the board or panel, the faster and simply mount And less required fasteners.

It is absolutely possible to accept these tips in relation to facade panels And other DPK products for plane cladding.

The industry provides an average opportunity to make its choice - use the new natural material to which natural resources (wood, stone) go or apply the products of recycling recycling. Today, people have learned to convert natural material processing waste into products, ahead of these materials by properties. However, the choice remains beyond a person - either dispose of garbage, acquiring DPK, or create it more and more, giving preference to natural materials.

Modern building materials should be not only aesthetic, but also practical, simple in circulation and care, but most importantly - economical. Many enterprises operate in the field of the invention of new materials, directing research mainly on combinations of various substances, and among them you can allocate such a promising novelty as wood-polymer composite (DPK).

DPK is often called Liquid tree , or topoplastic , and lovers to the knowledge of English call him polwood . From these names it is clear that it is a compound of plastic and wood in the molten state, followed by solidification of the final product. Liquid wood is an alternative wood of expensive varieties, and, moreover, has significantly improved operation characteristics compared to any tree or plastic. In the light of modern fashion on environmental materials polymer composite - This is the necessary improvement of materials used for cladding, flooring, manufacturing panels and "boards" and many other construction and finishing materials. The widest use of the wood-polymer composite received in the field of manufacture Terraced boards (Decing).

The most popular option applications of DPK - Terraced board or Decking

Properties and characteristics of wood-polymer composite

The DPK consists mainly of wood fibers whose role is successfully carried out by woodworking and plastics, as a binder substrate. As a result, the resulting material combines all beneficial features modern polymers and natural wood.

Wood qualities of liquid wood are manifested in:

• authentic wooden drawing, texture and color;
• similar thermal conductivity;
• characteristic aroma;
• security for the environment and for the consumer.

The polymer part of the DPK gives it such properties as:

• high moisture resistance, because of what you should forget the problem of booting boards;
• strength and wear resistance, thanks to which the DPK products are not afraid of loads, shocks and constant abrasion. Shoes, claws of animals, falling items do not leave on the surface of visible traces. In addition, even being moistened, the terrace board of the DPK does not slide, which is so important when used on the floor, as steps and, naturally, terraces, veranda, open areas and even (garden parquet);
• heat resistance and ability to withstand extreme weather conditions;
• inedistence for insects, fungi, as well as concurrent bacteria;
• ease of processing and installation (an example of the construction of a terrace of DPK);

As a result, a liquid tree is unlike all well-known building materials, at the same time:

• Reliably, durable and beautiful;
• Does not require any care, except for wiping dust. Cyclumin, lacquer treatment, paint coating and other manipulations are whims of a tree, the wood-polymer composite in them simply does not need;
• Economically. Compare DPK with natural wood at a cost simply no sense, and plastic is becoming more expensive over time due to the fact that it requires frequent repairs and replacements. That is, a wood-polymer composite, which will easily serve you a quarter of a century, will survive a few shifts of plastics and wood, because of which its cost in the total account decreases several times.

The variety of products from DPK is truly limitless

Scope of wood-polymer composite

Such undoubted advantages led to the use of DPK in the field of construction and even the internal finishing of cars and yachts, and due to the excellent water resistance, it is used to build structures of frequently injecting water or constantly in it: Basins, Person and Persons, Small bridges, some details Shipbuilding and even sea piles (!).

Garden parquet of DPK is great for paving outdoor sites and terraces, as well as garden tracks.	Modern siding or lining from DPK, successfully replaced vinyl, metallic and cement siding.
Flower beds and DPK flower beds are becoming increasingly popular thanks to durability and ease of installation.	Fences and fences from DPKs are no externally different from wooden, but do not require regular processing and replacing the rotten boards

In a private house-building, a wood-polymer composite becomes material No. 1 when installing various flooring, garages, a dance flooring, a veranda, terraces and fences. In addition to all of the liquid wood, excellent garden structures are obtained: gazebos, terraces, tracks, fences, wickets - and all due to resistance to a wide range of temperatures, ultraviolet sunlight and the influence of living organisms. And what facade cladding can be done with the help of DPK!

Easy, thermo- and moisture-resistant, easy to install and, moreover, an environmentally friendly wood-polymer composite becomes an excellent substitute for Eurovantia and. It also produces excellent window sills and countertops, furniture and doors of any type (both input and).

Most common in the world building materials from DPK - DeconAlso called a terraced board. From Decing create floor coverings In the interiors, also in rooms, where the humidity is often elevated: a bath, a sauna, a bathroom. All the positive qualities of the DPK work when using it for outdoor decoration Constructions: already mentioned balconies, terraces, operated roofs, veranda, piers, marins and decks of ships.

The terrace board is a traditionally profile product with variable configurations. Also manufacturers recommend using a hollow or solid decoing profile for different species The intended load on the coating.

It is also very common with a DPK product called garden parquet. Externally, it looks like a tile coating with segments of about 30 to 30 cm. But the parquet itself is made up of a plastic substrate to which the slats of the wood-polymer composite are attached. Special substrate attachments make it easy and easy to install and collect back the flooring, which causes its use in seasonal buildings, sites or on private suburban areas.

Tiles from DPK - Garden Parquets are able to two layers: substrate base and facial	Garden track paved with DPK tiles - Garden parquet

Where did this amazing material come from?

Created a wood-polymer composite (DPK) in Italy. Back in 1974, the ICMA San Giorgio concern received a patent for the authorship of this building material for which Wood-Stock brand was created. Now you can clearly see all the prerequisites for such an idea - after all, the company before it was engaged simultaneously with the traditional woodworking and the manufacture of polymer plastic products. The cost utilization of waste of both industries has become a problem that was economically solved by the association of both directions. But then the new building material was not just a novelty, but standing on the verge of fiction, so he had to deserve consumer confidence for a long time.

DPK production technology requires careful compliance technological process and high quality raw materials. The processes of improvements and improvements of manufacturing technology, and then the material itself dragged up to the eighties. And the remission of the consumer is not a liquid tree not in Italy, but on the largest auto plants in the world. Now practically everyone is dealing with DPK, but it may not even guess about it, because most car salons are made precisely from it - a wood-polymer composite.

Wood-polymer composite - production in production

Composition and manufacture of wood-polymer composite

If we consider the composition of the DPK more, its changes are traced from the beginning of production to modernity, and now approximately: the crushed wooden filler, which gives the main volume of the product, is associated with a polymer of one of three species. The purpose of the finished product determines the choice: polypropylene, polyvinyl chloride (PVC) or classic polyethylene. Plastic with filler binds and turn into a single monolith.

Actively used in the manufacture of liquid wood additives - various additives necessary to give the composure of the necessary operational properties. Their role in liquid trees Chemical industry products play:

• kolorals to give color;
• modifiers for strength and hardness;
• lubricants for better moisture resistance and fast extrusion;
• foaming reagents to impart the lightness and smoothness of the surface;
• biocides for maximum resistance to the effects of biological nature factors.

Disadvantages of the Polymer Composite

The disadvantages of the materials made of wood-polymer composite include poor tolerability with constant simultaneous impact of combinations of two negative effects - high humidity and high temperature, which leads to a rapid wear of the Coverage of the DPK.

The appearance of mold with insufficient ventilation of the room with which only specific and expensive additives allow them to fight. Its value compared to the budget tree still remains the main disadvantage.

The nearest natural competitor to the DPK can be a larch or more rare Bankeirai tree (Bangkirai), which is sometimes even twice as cheaper, and properties have almost identical. The difference is manifested only in those places where the use of one material is impossible and it is replaced by another.

Technical and operational characteristics of the wood-polymer composite (DPK) and larch

The larch will manifest itself much better in the bath or sauna (high temperatures in combination with humidity - remember?), But the wood-polymer composite will last much longer last the open sky, as the wooden building materials in the air always need regular additional processing and replacement.

Polymer composite is one of the popular species of wood composites, which combines the advantages of wood and plastic. Together with this lack of natural wood material is deprived. Each familiar precursors of this material are familiar, among them should be allocated:

Why choose DPK?

These materials consist of chips or sawdust, as well as a binder. Compared to natural wood, they cost cheaper, and in certain indicators exceed their natural analogue according to the characteristics, which determines the direction of their use.

Features of production

Wood-polymer composite became the result of new developments. This material is innovative, it belongs to the new generation and is characterized by a wide area of \u200b\u200buse. In its composition, it has woody flour, modifiers and thermoplastic polymer. Flour can be replaced by the waste of agricultural processing, which allows you to reduce the cost of products. As for modifiers, they are needed to give the product special properties. Flour and polymer are used in a ratio, which depends on the class and material producer.

The cheapest option contains 70% flour and 30% polymer, which makes the material hydrophilic, more fragile and less wear-resistant. If you apply an equal ratio, then it will be possible to obtain a material with optimal properties. Wood-polymer composites may contain 40% flour and 60% polymer, which affects the aesthetic properties of the material. DPK externally looks like plastic, but it turns out more durable and resistant to external factors. The composition has chemical additives in the form of modifiers, their presence does not affect environmental friendliness, because the amount does not exceed 5%.

In the manufacture, an extrusion is used, which provides for the production of a polymer product with a molding method in the molten form through the molding hole of the machine, the latter is called an extruder. Rightly, wood-polymer composites are made according to the molding method under pressing and pressure in forms.

Main characteristics and area of \u200b\u200buse

Materials made of wood-polymer composite are designed to arrange objects that are exposed to the external environment. If exploitation is carried out under the open rays of the Sun and high humidityThe composite board must have special properties. This also applies to those conditions if it is used with temperature fluctuations.

The wood-polymer composite board has a long service life even in an extreme climate. She is ready to serve from 15 to 50 years. Material has the following qualities:

• wear resistance;
• resistance to ultravioleti;
• moisture resistance;
• high strength;
• resistance to temperature drops;
• immunity to pests and mold;
• lack of need for special care;
• resistance to aggressive solutions;
• the possibility of recovery after severe pollution;
• high fire resistance;
• convenient installation and disassembly;
• environmental Safety;
• good thermal conductivity;
• high aesthetic qualities.

As for wear resistance, the material is resistant to scratches and abrasion. There are no off-bements on it, it can be used even in places with maximum permeability. Under such conditions, the coating retains the initial appearance. The material is not destroyed and does not fade, does not swell, does not change the form when dried. It is resistant to temperature drops, and it can be operated from - 50 ° C to + 70 ° C. Material high strength, it withstands high loads and does not crack from shocks. He is susceptible to pests and mold.

Wood-polymer composite products do not require special care and additional coating, as well as applying antiseptics. It can affect acids, alkalis and aggressive solutions.

Framework material, it does not support combustion and cannot ignite from spark or cigarette. Mount and dismantle it is quite simple. The mount is well thought out, the profile can be bent, drilled and saw.

Another advantage of the wood-polymer composite panels is environmental safety. Material does not highlight environment Harmful substances can be used for recycling, it does not clog the external waste. Boards of thermal conductory by analogy with wood. You will not feel cold if you run on the surface of the barefoot.

Aesthetic quality material is high. It has a color, texture and aroma of natural wood. A huge variety of solutions with different textures and color options is available on sale. The wood-polymer composite for the facade has all the above characteristics, which means its main advantages are:

• high moisture resistance;
• lack of treatments and special care;
• practicality;
• durability.

Material can be used even by the sea. But, like each solution for construction and repair, such composites have shortcomings, one of them is a high cost. The minus is also the risk of being a deceived unfair manufacturer.

Distinctive features

During the production of a wood-polymer composite, different raw materials can be used, which affects the final characteristics. In the manufacture, a different ratio of the main components can be used. In addition to wood flour, the filler can perform cake sunflower seeds. Sometimes the waste paper or rice husk is used. Polyvinyl chloride is a binding thermoplastic polymer. Polyethylene or polypropylene performs the same role.

In the production of wood-polymer composite, boards can be obtained, the density of which varies from 700 to 1200 kg / m 3. Strength can also be different, which is influenced by full or hollowness. Products can have one, two or more layers. The surface is sometimes processing in the form of embossing, it can be sealing or apply to the printing board.

The outer layer can be a protective polymer coating. Sometimes paints, synthetic films or lined veneer are used. As a rule, a terraced composite board has one of two types of surfaces, it is a texture under a tree or relief.

Dimensions

In the width and length of the panels may have certain dimensions. If you want to separate the facade, you should choose the board of the appropriate destination with a width of 8 to 12 cm and from 18 to 20 cm. The intermediate value is the limit of 14 to 16 cm. The thickness of the panel can vary from 1 to 2.1 cm. Length It is equal to the limit of 3 to 6 m. The terrace board is characterized by a thickness that can be 4 cm. The minimum value is 2.5 cm.

Use options

From the wood-polymer composite is manufactured:

• batten;
• terraced board;
• profile for roofing;
• facade board;
• profile for interior wall decoration;
• siding.

The boards are used in the construction of private saunas, street cafes, with the arrangement of garden sites and the installation of the arbors. In the urban area of \u200b\u200bthe product used to finish loggias and balconies.

DPK for gardeners

Quite often today is used wood-polymer composite for beds. This method of arrangement pricework There are many advantages. First, the assembly of structures is quite simple and takes little time. Secondly, the flights are fixed separately. Thirdly, the material eliminates the formation of fungus and mold on the surface. Such boards are not exposed to harmful insects.

The fence has a rather attractive appearance, and even patterns and drawings can be seen on the surface. The material can be processed by paintwork. Constructions are environmentally safe and do not distinguish harmful substances into the external environment. The composite has a smooth surface and a face that does not hit a person during work. Boards are resistant to adverse effects, they are able to withstand high mechanical exposures of the load and allow us to design a bed of any height. Finished products are easy to disassemble and transfer to another place.

Doors from DPK.

The wood-polymer composite doors are very resistant to external influences, so it is possible to use them in rooms with intensive operation. They are quite often installed for use in conditions with unstable temperature and humidity. The described material is also called liquid wood, which in the product has aesthetic appearance and demonstrates durability.

The composite is rather mild, so scratches can remain on its surface. In order to avoid damage, the door must be operated carefully. But if there are animals and children in the house, it is better to choose products, the surface of which is made using the brash technology. The base in this case has roughness, which makes small scratches invisible.

The main advantages and application of siding from DPK

Siding from the Polymer Composite today is very popular. It does not allocate and does not absorb moisture, so it does not sit down and does not give a seniority. The surface is not covered with cracks and is not deformed when changing the weather cycles. The finish is characterized by high heat and sound insulation. It is not affected by bacteria, fungi, as well as insects.

The material does not form rust has a high frost resistance. IN winter The house is well preserved warm. This type of siding is characterized by simplicity of care, the facade will sufficiently wash water periodically, and it can be used detergents. Active cleaning solutions, however, should not be used, like brushes, as well as cleaning sponges that have abrasive or metal elements.

Thanks to the available qualities, siding from DPK is widely used for internal finishing work And in facing facades. It has excellent quality and durability, which means it is ready to give a cottage or home natural beauty.

The main flaws of siding

Whatever perfect siding from DPK, it has some cons. For example, the cost. High-quality panels are quite expensive, and cheap will not be able to please long service life.

Products are presented on the market with a fairly small selection of forms. But this minus some are called conditional. Despite the fact that DPK-siding is manufactured in one format, thanks to the features to treat, this minus can be partially compensated.

Conclusion

The most sought-after building material always has and remains wood. It is universal in processing and has high thermal insulating aesthetic qualities. When creating unusual architectural buildings and decorating the interior of wood out of competition. The only disadvantage is an exposure to external factors. Manufacturers sought to reduce all flaws and invented innovative building material, which is called a wood-polymer composite.
