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.
Peristaltic Dosing Pumps Characteristic :
1 Clean and pollution-free: fluid only passes through and touches the Peristaltic Pump hose.

3. Low shear force: It is an ideal tool for conveying shear-sensitive and corrosive fluids.
4. Corrosion resistance: it can transport various fluids, such as organic solvents and corrosive liquids.
5. Idling and dry operation: air or gas-liquid-solid three-phase mixed transportation can also be transported.
6. Possess self-priming ability: self-priming, no need to fill the pump, no need to empty.
7. It has the function of a shut-off valve, does not siphon, has no seals, and has the functions of a shut-off valve and a check valve.
8. Two-way conveying function: reverse pumping and back-suction functions can be realized by changing the direction of the pump runner.
9. Simple maintenance: only need to replace the peristaltic pump hose, no valve and seal replacement.
