Classification of Fiberboard

Generally divided into two categories of non-compressed and compressed according to product density. Non-compressed products are soft fiberboard with a density of less than 0.4 g / cm3; compression products include medium-density fiberboard (also known as semi-rigid fiberboard with a density of 0.4 to 0.8g / cm3) and hard fiberboard (with a density greater than 0.8g / Cm3). According to the slab forming process, it can be divided into wet fiberboard, dry fiberboard, and oriented fiberboard. According to different post-processing methods, it can be divided into ordinary fiberboard and oil-treated fiberboard. Soft fiberboard is light in weight and has a large porosity. It has good heat insulation and sound absorption. After special treatment, light fiberboard with more pores can be obtained, which has adsorption performance and can be used for air purification. Medium-density fiberboard has a uniform structure, moderate density and strength, and good reworkability. The product has a wide range of thicknesses and has a variety of uses, such as furniture materials and TV housing materials. Hard fiberboard products have a small thickness range, between 3 and 8 mm. High strength, 3 to 4 mm thick hard fiberboard can be used instead of 9 to 12 mm sawn timber sheet. Mostly used in buildings, ships, vehicles, etc.
