Wood plastic composite material, WPC is booming in recent years as a new type of composite material. WPC use polyethylene, polypropylene and PVC etc, instead of the usual resin adhesive, mix with more than 35% to 70% of wood powder, rice husk, straw waste plant fiber blend into wooden material, then through extrusion, mould pressing, injection moulding processing put out to board and profile. It mainly used in building materials, furniture, logistics packaging industries.
Wood-plastic composites contain plastics thus have good elastic modulus. In addition, as WPC contains fiber and classics to mix adequately with plastic, it has the physical mechanical property such as resistance to pressure, resistance to bending comparing to hard wood. And its durability is better than average woodiness material apparently. The surface hardness is high, generally 2-5 times than wood.
1, WPC granulation machine
After get ready wood powder and recycled PP/PE plastic, the first step is mixing them with chemicals, then use WPC granulation machine to make WPC granules
SHMS series granulating machine is used for making WPC pellets. The WPC pellets produced by WPC granulating machine can used for making WPC product using WPC machine.The granulating machine consists of parallel double-screw extruder,water cooling system, a granulator and air conveyor cooling system.The feeder and hopper are equipped with mixer to prevent the material blocked up.If customer do not have strict requirements about the appearance of pellets, the granulator can be removed.The pellets extrude by extruder directly, then go for crusher. Can improve the production capacity.
