Wood plastic material
Thread Content
Wood plastic, also called wood plastic or wood plastic material, wood plastic is a composite material made of low-value biomass fibers such as sawdust, wood chips, bamboo chips, rice husks, wheat straw, soybean hulls, peanut shells, sugarcane bagasse, cotton straw, etc., and is synthesized with plastic. It has the advantages of both plant fiber and plastic, and has a wide range of applications, covering almost all fields of use of logs, plastics, plastic steel, aluminum alloys and other similar composite materials. It also solves the problem of recycling waste resources in the plastic and wood industries. Its main features are: Resource utilization of raw materials, plasticization of products, environmental protection of use, economical cost, and recycling. Current research focuses on composite materials made from thermoplastics such as polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), and polystyrene (PS) and wood powders such as wood powder, plant straw powder, and plant seed husks as raw materials, through extrusion, injection molding, and compression molding. From the perspective of production raw materials, the raw materials of wood-plastic composite materials can be various waste plastics, waste wood and crop residues. Therefore, the development and widespread application of wood-plastic composite materials will help slow down the pollution of plastic waste and also help reduce the environmental pollution caused by the burning of agricultural waste. The production and use of wood-plastic composite materials will not emit volatiles that are harmful to human health into the surrounding environment. The material itself can also be recycled. It is a new green environmentally friendly product and an ecologically clean composite material. Therefore, research on the preparation and processing of wood-plastic composite materials contains huge economic and environmental benefits. Are there any seniors in the wood plastic field? I hope you can have an in-depth discussion on the raw material composition and process of wood plastic flooring!
Why don't I see anyone replying? I am in urgent need of knowledge in this area＼:L Where is the expert? You can also send it to me directly: hehongli817@yahoo. com. cnThank you!
I need it too. Please give me more. Thank you.
I can provide you with a formula. This formula has been tested in the laboratory and has better performance. 100 parts of PVC (SG-5), 6 parts of DOP (dioctyl phthalate), 5 parts of calcium carbonate, 2 parts of ACR-401, 4.5 parts of rare earth stabilizer, and an appropriate amount of aluminate coupling agent-XL-955 (add it according to your raw materials during the experiment). Wood powder processing adopts the coupling method. Explain that the aluminate coupling agent - Equipment plastic grinding mill, dryer, mixer, high speed mixer, extrusion granulator. Conical twin screw extruder.
In fact, for wood-plastic materials now, we not only have to face how to make them, but also how long they can be used after they are made - performance aging problems, mold problems, discoloration problems, etc. I hope we can make good products, not like Sanlu milk powder. . .
As mentioned above, it is necessary to be fully prepared before industrialization.
There is a wood plastic company near me. I want to go in and have a look. Unfortunately, I don’t have much. I want to learn here first.* study *
Real industrialization is not that easy.
What are the main additives used in the wood plastic production process? What is the appropriate temperature for melting PE, PVC and wood powder?
