Germany develops moldable plastic wood materials

Germany has developed a plastic-wood material that can be molded like plastic. It can be used to mold wood products such as floors, doors and windows, and furniture. It can also be used to make televisions, computer cases, and car doors and gears. Mud board and so on. The existing ordinary wood is mainly composed of cellulose and lignin, and the cellulose gives it a certain strength, and the lignin and the cellulose bind together, so that the wood has toughness. Based on this principle, a German research team mixed natural cellulose with lignin discarded as waste by paper mills to form granules, which were then placed in the cavity of an ordinary injection molding machine at high temperatures and pressures. Under the conditions, the plastic wood material composed of cellulose and lignin is tightly combined and processed into the desired shape to form a new molded plastic wood product. This moldable plastic wood material has a wide range of uses, especially products that can be used to make a combination of wood and metal parts. In the past, cracking of wooden parts was apt to occur due to the fact that plastics and metals swelled more than wood; cracking was now avoided with parts made of plastic wood.
