Problems solved by technology

[0002] Wood-plastic flooring is a new type of environmentally friendly wood-plastic composite material product. The wood phenol produced in the production of medium and high-density fiberboards is added to recycled plastics to make wood-plastic composite materials through granulation equipment, and then extruded for production. It is made into wood-plastic floor; however, wood-plastic floor has poor water resistance, is easy to oxidize, and has a short service life. At the same time, because it is placed outdoors, it has poor absorption of ultraviolet rays and will directly reflect to the crowd, causing certain harm.
