A:Wood-plastic products are prone to aging, deformation, fading and other problems when exposed to natural environments such as sunlight, rain, and temperature differences. These problems not only affect the aesthetics of wood plastic products, but also reduce their service life. Therefore, it is crucial to solve the weather resistance problem of wood plastic products.
A:In the wood plastic production process, wood powder content is a very important parameter. It directly affects the performance, cost and environmental protection of wood-plastic materials. The higher the wood powder content, the better the environmental protection of the wood-plastic material, but it will also affect its strength and durability. Therefore, how to find a balance point to make wood-plastic materials both environmentally friendly and practical is the key to the wood-plastic production process.
The screw extruder relies on the pressure and shear force generated by the rotation of the screw, which allows the material to be fully plasticized and evenly mixed, and then formed through the die. [2] Plastic extruders can be basically classified into twin-screw extruders, single-screw extruders, and rare multi-screw extruders and screw-less extruders.
