Wood-plastic composite material is a new composite material that has emerged in recent years. It refers to the use of polyethylene, polypropylene, polyvinyl chloride, etc., instead of commonly used resin adhesives, it is mixed with wood flour, rice husk, straw and other discarded plant fibers of 35%-70% or more into new wood materials. Sheet or profile made by extrusion, molding, injection molding and other plastic processing processes. Suitable for construction materials, furniture, logistics packaging and other industries. Hot extrusion is a kind of extruded wood plastic composite board made of plastic and wood powder mixed in a certain proportion.


Wood plastic door factory brief.


Because wood - plastic composite material contains plastic, so the elastic modulus is better. In addition, because contain fiber, and mix fully with plastic, have with hardwood equivalent to resist compression, resist bending and other physical mechanical properties, and its durability is obviously better than general wood materials. Surface hardness is high, generally 2-5 times that of wood.


Wood floor processing.


Artificial zeolite can be added to the polymer. When the molecule captures the powder, it can absorb the odor in the material. The adsorbent can capture odor-producing organic small molecules through a large number of crystalline holes in the powder. Molecular capture adsorbents have been successfully used in polyolefin extrusion pipes, blow molding vessels, isolation packaging materials, extrusion outer packaging and sealing materials. Molecular adsorption powder can be added to the plastic as a dehumidifier to remove water and gas.


The different sizes and shapes of extruded products increase the diversity of WPC composites.


WPC profiles can be made by injection molding or molding, without continuous sheet structure or complex parts structure. In the process of processing wood-plastic materials, processors sometimes face mold filling problems. To solve this problem, they need to reduce the wood filling amount to increase the fluidity of the melt.


Because 200°C is the upper limit of processing temperature for WPC, certain resins with melting points above 200C, such as PET, cannot be used in WPC.


Water and gas will deteriorate the properties of the composite and help to breed microbes, so wood fillers must be removed before use. Wood filling materials should be dried before processing and forming, and generally the water content after treatment is less than 1~2%.


Wood plastic composite processing machinery requires feeding equipment, drying equipment, extrusion equipment and molding equipment, as well as some necessary downstream equipment such as cooling water tank, traction equipment, cutting equipment, etc..


Processing.


In the process of polymer and wood powder surface modification, the interface affinity between wood powder and resin can be improved by adding appropriate additives.


The dispersion effect of high charge wood powder in thermoplastic melt plastic is poor, resulting in poor fluidity of melt and difficulty in extrusion molding. Surface treatment agent can be added to improve fluidity and facilitate extrusion molding.


In order to improve the processing performance and service performance of the product, the plastic matrix also needs to add various additives.
