Monofilament filter cloth is a new generation of filter material, which is widely used abroad and its price is higher than ordinary filter cloth. There is no authoritative national and industrial standard in China.            Materials: nylon, polyester, polypropylene and polyvinylidene fluoride.            Performance: high filtration efficiency, easy to clean, high strength, service life is 10 times of ordinary fabric, the highest filtration accuracy can reach 0.005 μ M.            Technology: heavy duty rapier loom weaving, single layer weaving, double layer weaving, three layer weaving, etc.            Product coefficient: breaking strength, breaking elongation, thickness, air permeability, wear resistance and bursting force            Application: for alumina, phosphate fertilizer industry, cement, smelting, chemical industry, chemical fiber and other continuous production environment, nonferrous metals such as zinc oxide, cobalt oxide, alumina, potash fertilizer, nickel cobalt ore, manganese ore and other mineral smelting, dye chemical industry, coal mining and processing industries, it is suitable for belt filter, vacuum drum machine, (flat plate, turntable, vertical plate) filter, leaf filter, candle filter Machine, closed filter, press and other equipment.            Development: in China's coal preparation, metallurgy, chemical industry, environmental protection and other industries for solid-liquid separation of suspensions, most of them use multi filament woven filter cloth and non-woven needle felt for separation. But in the world, since the 1990s, monofilament filter cloth has been used for solid-liquid separation, and the work efficiency has been significantly improved. However, due to the high price of imported monofilament filter cloth, only a few domestic units with high requirements for solid-liquid separation process use imported monofilament filter cloth. With the development of domestic market, the monofilament filter cloth produced by a few large-scale manufacturers, such as hechuang filter, has reached or approached the world level. Because of its high cost performance, it has been developing rapidly since the 21st century
