In the solid-liquid separation of suspensions in coal preparation, metallurgy, chemical engineering, and environmental protection industries in China, most of them use multifilament woven filter cloths and nonwoven needle felts for separation. However, in the world, since the 1990s, monofilament filter cloths have 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 that require high solid-liquid separation process technology use imported monofilament filter cloth. With the development of the domestic market, the monofilament filter cloths of a few large-scale manufacturers, such as Hechuang Filter, have reached or approached the world level, because of their high cost performance, they have developed rapidly since the 21st century, and have been exported in large quantities.
Monofilament filter cloth Monofilament filter cloth Introduction: Monofilament filter cloth is a new generation of filter material, which is widely used in foreign countries, and its price is higher than ordinary filter cloth. Now there is no authoritative national and industry standard in China.
Material: Nylon, polyester, polypropylene and polyvinylidene fluoride.
Performance: high filtration efficiency, easy cleaning, high strength, 10 times longer service life than general fabrics, and the highest filtration accuracy can reach 0.005μm.
Process: heavy rapier weaving, single layer weaving, double weaving, three layers weaving and so on.
Product factors: breaking strength, elongation at break, thickness, air permeability, wear rate, and bursting force.
The advantages monofilament filter cloth:
1. A single synthetic fiber is woven, strong, not easy to block, there will be no broken yarn.
The
2. the surface of the heat setting treatment, high stability, not easily deformed, uniform pore size.
The
3. the surface of the monofilament-treated monofilament filter cloth, the smooth surface of the cake is easy to peel, filter cloth easy to clean and easy regeneration.
