Polymers can add some artificial zeolite, aluminosilicate this molecular powders can capture the odor-absorbing material. By amount of crystalline powder empty, the adsorbent 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, extrusion packaging and sealing materials. Molecular adsorbent powder can also be added as a desiccant to remove the plastic moisture.
When the profile is not required to have a continuous sheet-like structure or component has a complicated structure design, WPC profile can be formed by injection molding or compression molding. Processors sometimes have to face the WPC in the process how to complete filling of the problem in order to solve this problem, they need to reduce the amount of wood filler to increase the melt flow. Since the upper limit is 200 ℃ WPC processing operating temperature, some of the resin melting point exceeds 200 ° C, such as PET, it can not be used for wood-plastic composites. Moisture can degrade the performance of the composite material but also contribute to the breeding of microorganisms, so be sure to remove moisture prior to use wood filler.
Before molding wood filler should be dried, generally require moisture content of the treated less than 1 to 2%. Now WPC processing machinery requirements with feeding equipment, drying equipment, extrusion equipment and molding equipment, and the necessary downstream equipment such as cooling water tank, traction equipment and cutting equipment.
