The key technology of WPS is how to ensure the high filling amount of rice husk powder, which can make rice hull powder fill up to 80% ~ 90% to achieve low production cost and high performance. How to ensure high fluidity and permeability of the material in the high filling amount of the premise so as to promote the thermoplastic melt adhesive can fully bind the rice husk powder to achieve the common mechanical properties and other aspects of the performance, Solve the following aspects:

(1) the surface treatment of wood powder (2) raw materials (plastic, rice husk powder type) choice and how to improve the interface between plastic and rice husk powder binding. Because the two-phase composite interface tends to be a stress concentration area, the key to improve the mechanical properties of the composite is to improve the interface compatibility. Wood molding process includes the crushing of plastic, cleaning, drying and granulation, wood powder drying, processing, wood-plastic mixture and product molding process.

Wood-plastic products, including several forms of molding processing: extrusion molding, rolling molding, injection molding, pressing molding and so on.
At present can be used for wood-plastic extrusion molding equipment are single screw extruder, twin-screw extruder. Conventional single-screw extruder in the wood-plastic composite extrusion is subject to greater restrictions. WPC can be used for forming single-screw extruder must be designed with a special screw, screw should have a strong material handling and mixing plasticizing capacity, and often in the extrusion before the material mixing granulation.
