Wood-plastic composite processing machinery is equipped with feeding equipment, drying equipment, extrusion equipment and molding equipment, as well as some necessary downstream equipment such as cooling water tanks, traction equipment and cutting equipment. Since 200 ° C is the upper limit of the operating temperature of the wood-plastic composite, some resins at temperatures greater than 200 ° C, such as PET, can not be used in wood-plastic composites.
Water vapor will degrade the properties of the composite and also contribute to the breeding of microorganisms, so water vapor must be removed before using the wood filler. Before processing the wood filler to be dried, the general requirements of the treated water vapor content is less than 1 ~ 2%.
