"Eco-wood, also known as wood, is processed by extrusion, ecological wood composite extrusion molding refers to thermoplastics and lignocellulosic material in an extruder by heating, pressurizing the heated and molten plastic mixing lignocellulosic materials, plastics, and finally almost continuously processed through a die molding method. All thermoplastics extrusion, plastic molding collar city. one of the important methods of processing, short cycle, high efficiency can be realized continuous production, is a low power high-yield production process. for the production of ecological wood composite extrusion process with stable product quality, low cost, relatively small investment, etc., so the development of faster. how ecological wood performance? current ecological wood composite extrusion products is very wide as industrial pallets, window profiles, decking, flooring, decking and profiles and the like.
Since ecological wood composite extrusion molding is the use of traditional plastic extrusion processing methods. By dipping the extrusion equipment it is mainly based on plastic extruder adopted improvements. To meet the processing requirements of ecological wood composites. However, the addition of the lignocellulosic material. Making plastic rheological behavior change. Meanwhile lignocellulosic material and a heat-sensitive materials. These factors led to the Ministry of extrusion equipment and processing principles and have different ecological wood plastic composites. In the country mainly for traditional plastic extruder improvements. In foreign countries have developed specialized processing ecological wood composite materials for extrusion equipment. Currently extrusion production of ecological wood composites main equipment screw extruders, including single screw extruder and a twin screw extruder. Wherein the twin screw extruder comprises parallel twin screw extruders and conical twin-screw extruder.
In addition, the use of dual stage twin screw extruder and single screw extruder series formed by extrusion unit, the production of wood-plastic composite material has certain advantages.
Extrusion molding production process ecological wood composite materials are generally divided into one-step and two-step method. One Step is assigned a raw material mixing, devolatilization and ecological wood products out within a device or group of devices to complete a row. The two-step process is usually divided into mixing and granulating ecological wood composites and extrusion molding two stages.
