Germany has developed a new plastic wood material

Germany's Langhofer Institute of Chemical Technology has recently developed a plastic-wood material that can be molded like plastic. It can be used to mold floors, doors, windows, furniture and other products. It can also be used to make televisions and computers. Shells, boxes (boxes), and car doors and fenders.
The existing ordinary wood is mainly composed of cellulose and lignin. The cellulose has a certain strength, and the lignin and the cellulose combine to make the wood tough. Based on this principle, the Institute mixes natural cellulose with the lignin discarded as waste by paper mills to form granules, which are then placed in the cavity of an ordinary injection molding machine under high temperature and pressure conditions. Next, they will be closely combined together to form a plastic wood material, processed into the desired shape, and made into new molded plastic wood products.
According to reports, the appearance of this moldable plastic wood material was favored by furniture manufacturers, packaging materials, and decorative materials. Swedish IKEA furniture company believes that although molded wood products have a history of more than ten years, but so far, molded wood is composed of wood fiber and binding resin, its mechanical properties are similar to the performance of the composition resin, only Used to make hollow doors and automotive interior parts. The new type of plastic wood material is different, it can almost reach the performance of natural wood, completely called the authentic wood, with its molded product is no different, even due to temperature changes caused by shrinkage or expansion The degree is also no different from natural wood. The moldable plastic wood material has a wide range of uses and can be used not only to mold floors, doors and windows, furniture, and packaging boxes (boxes), but more importantly, it can be used to manufacture products combining wood and metal parts. In the past, cracking of wooden parts was apt to occur because plastics and metals expanded more than wood. Now that you use components made of plastic wood, you can avoid this problem.
