Problems solved by technology

[0003] Wood-plastic flooring is a floor made of wood-plastic composite materials. It has the same processing characteristics as wood and can be used like ordinary wood. Very durable outdoor waterproof and anti-corrosion building materials. It has the characteristics of rich styles, pollution resistance, flame retardant, moisture resistance, environmental protection, no fading, easy installation and easy care. However, because it is based on wood, it also has poor load capacity. The wear resistance cannot meet the characteristics of the demand, which needs to be solved urgently
