Density board is a commonly used building material with a wide range of applications. It is made of wood or other fiber materials, pressed at high temperature, and has certain strength and stability. Density boards can be divided into high-density fiberboards, medium-density fiberboards and low-density fiberboards according to their density. Among them, the nominal density of medium-density fiberboards ranges from 0.65g/cm3 to 0.80g/cm3. The application range of density boards includes but is not limited to laminate flooring, door panels, partitions, furniture, etc. In home decoration, density boards are mainly used for surface treatment of mixed oil processes. Medium-density fiberboards are generally used to make furniture, because high-density fiberboards have too high a density and are easy to crack, so they cannot be used to make furniture. High-density fiberboards are usually used for interior and exterior decoration, office and civil furniture, audio equipment, vehicle interior decoration, etc.
