The introduction WPC materials processing

WPC: 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 composite profile is not required when a continuous sheet-like structures or components with complex 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 is required with the feeding equipment, drying equipment, extrusion equipment and forming device, there are some necessary downstream equipment such as cooling tanks, traction equipment and cutting equipment.
