Water vapor degrades the properties of the composite and helps to breed microorganisms, so it is important to remove the moisture before using the wood filler. Processing before molding the wood filler to be dried, the general requirements of water vapor content after treatment to less than 1 to 2%.[url=http://wpcfloordecking.com/blog/outdoor-pvc-fence.html]outdoor PVC fence[/url] Now the wood-plastic composite processing machinery requires the feed equipment, drying equipment, extrusion equipment and molding equipment, there are some necessary downstream equipment such as cooling water tanks, traction equipment and cutting equipment. Raw materials, the need for appropriate additives to modify the surface of polymers and wood flour to improve the wood powder and resin interface between the affinity.[url=http://wpcfloordecking.com/blog/environmentally-friendly-wpc-fence.html]Environmentally friendly WPC fence[/url] The high dispersion of wood flour in the molten thermoplastic in the dispersion effect is poor, making the poor melt flow, extrusion processing difficulties, can be added to improve the flow of surface treatment agent to facilitate extrusion.[url=http://wpcfloordecking.com/blog/anti-slip-teak-boat-decking.html]teak boat decking[/url] Plastic matrix also need to add a variety of additives to improve its processing performance and the use of products performance. Feeding process, fluffy wood powder structure, not easy to feed on the extruder screw, in particular, wood flour contains more water often appear "bridge" and "pole" phenomenon. Instability of the feedstock results in crowding-out fluctuations, resulting in reduced extrusion quality and yield.[url=http://wpcfloordecking.com/blog/outdoor-flooring-materials-against-termite.html]Outdoor flooring materials[/url] Feed interruption, the material in the barrel to stay longer, resulting in material charred discoloration, the impact of the inherent quality and appearance of products. The use of forced feeding device and a reasonable way to ensure the stability of extrusion.
