It is usually divided into two categories, non-compressed and compressed, according to product density. The non-compressed product is a soft fiberboard with a density of less than 0.4 g/cm3; the compressed product has a medium density fiberboard (or semi-hardboard, density 0.4-0.8 g/cm3) and a hardboard (density greater than 0.8 g). /cm3). According to the slab forming process, it can be classified into a wet fiberboard, a dry fiberboard, and an oriented fiberboard. According to different post-processing methods, it can be divided into ordinary fiberboard and oil-treated fiberboard. The soft fiber board is light in weight, has a large void ratio, has good heat insulation and sound absorption, and is used as a covering material inside a public building. Specially treated to obtain a light fiberboard with more pores, which has adsorption properties and can be used for purifying air. The 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, housing materials for televisions, and the like. Hardboard products range in thickness from 3 to 8 mm. The high strength, 3 to 4 mm thick hard fiberboard can be used instead of 9 to 12 mm sawn timber. Used in buildings, ships, vehicles, etc.
Tempered or toughened glass is a type of safety glass processed by controlled thermal or chemical treatments to increase its strength compared with normal glass. Tempering puts the outer surfaces into compression and the interior into tension. Such stresses cause the glass, when broken, to crumble into small granular chunks instead of splintering into jagged shards as plate glass (a.k.a. annealed glass) does. The granular chunks are less likely to cause injury. Toughened glass is a kind of safety glass.
Toughened glass can be made on customer's request, clear toughened glass, ultra clear toughened glass, colored tinted toughened glass, printed toughened glass, back painted toughened glass, frosted toughened glass, toughened Laminated Glass, toughened Insulated Glass, toughened Vacuum Insulated Glass and so on.
Toughened glass can be used for furniture, buildings, doors, windows, walls, table tops, fence, partitions, railings, balcony, balustrade, shower room and so on.
