WPC is how processed

WPC containing plastic , which has good elastic modulus. In addition, due to the inclusion of fiber and sufficiently mixed with plastic , which has hardwood considerable compressive , flexural and other physical and mechanical properties, and its durability is better than ordinary wood . High surface hardness , typically 2–5 times the timber.

Wood Processing

Polymers can add some artificial zeolite, aluminum silicate molecules to capture this powder material can absorb the odor . By a large number of crystalline powder empty, adsorbents can capture odors of small organic molecules . Molecular adsorbent has been successfully used to capture the polyolefin pipe extrusion , injection and extrusion blow molded containers , isolated packaging materials, packaging and sealing material extrusion . Molecular adsorption powder can also be added as a desiccant to remove the plastic water vapor .

Different sizes and shapes of extruded products to increase the diversity of wood-plastic composites

When the profile is not required to have a continuous sheet -shaped member having a complicated structure or a structural design , WPC can be formed by injection molding or compression molding . Processed wood materials sometimes have to face in the process of how the problem of completely filling the mold , in order to solve this problem , they need to reduce the amount of wood filler in order to increase the melt fluidity .

Because the upper limit of 200 ° C operating temperature processing of wood-plastic composites , and some resin melting point exceeds 200 ° C , such as PET, can not be used for wood-plastic composites.

Moisture can degrade the performance of the composites , but also helps to breed microbes , so be sure to remove moisture prior to use wood filler. Before molding wood filler to be dried , generally require moisture content after treatment is lower than 1 to 2 percent .

Now WPC processing machinery requirements with feeding equipment, drying equipment , extrusion equipment and molding equipment , as well as the necessary downstream equipment such as cooling water tank, traction equipment and cutting equipment.

Wood plastic composite processing

For an appropriate additive to the surface of the modified polymer and wood flour , wood flour and the affinity to improve the interface between the resin .
Wood flour in a high loading of dispersed molten thermoplastics poor , so that the melt fluidity poor , extrusion processing difficulties , surface-treating agent may be added to improve the flowability in order to facilitate extrusion .

Plastic matrix also need to add various additives to improve the performance of its processing performance and its products .
