The existing ordinary wood is made up of cellulose and lignin, cellulose has the certain strength, lignin and cellulose together can make the wood resilient.
According to this principle, a German team of natural cellulose and paper mills as waste disposal of lignin mixed together, make its granulated substance, then, put it in the mold cavity of ordinary injection molding machine.
Under the condition of high temperature and high pressure, this kind of plastic wood materials composed of cellulose and lignin, is tightly integrated, be processed into the required shape, thus forming a new type of molded plastic wood products.
This can be molded plastic wood materials, has a wide range of USES, especially can be used to make a combination of wood and metal products.
In the past, due to the expansion of plastic and metal to a greater extent than wood, prone to cracking of wooden components, while the use of plastic wood material components, cracking can be avoided.
