Kogs PPS coated needle felt filter bag

Date of release:2018-03-26 Author: Click:

It is widely used in smelting, chemical, building materials, thermal power, waste incinerator, coal fired boiler and so on. It is a high - quality and high - temperature filter material. Our company selects polyphenylene sulfide fiber produced by the United States and Japan, according to other high temperature needling over felt production technology, specializing in the production of polyphenylene sulfide (PPS) needle felt, the product quality reached the level of similar products in developed countries.

PPS filter felt is one of the main varieties of high temperature resistant filter material, which is made and processed according to the production process of other high temperature resistant filter felt by our company, which is made of PPS fiber produced in the United States, Japan and other countries. The application of PPS needle punched filter material in the following occasions is excellent.

PPS is also called polyphenylene sulfide fiber. The fiber is a new type of high temperature resistant fiber developed by Phillip company and launched into market in 1983. At present, China's high temperature needle punched felt market is mainly made of needle punched felt with organic fiber NomexConex, Kermel and inorganic fiber glass fiber as raw material. The physical properties of organic fibers are obviously better than those of inorganic fibers. Polyphenylene sulfide fiber fiber is another kind of high function fiber in high temperature resistant organic fiber in recent years - not only can resist high temperature, but also has other high temperature resistant fiber with excellent corrosion resistance.

The advantages of needling and felting needles made of polyphenylene sulfide fiber are shown in the following aspects.

1, good temperature resistance, melting point 285 C, continuous use temperature 190 centigrade, instant usage temperature 230 centigrade.

2, excellent corrosion resistant polyphenylene sulfide fiber fibers are better than NomexConex and Kermel fibers in organic acids, inorganic acids, acids and oxidants.

3, excellent polar flame retardancy of polyphenylene sulfide fiber (LDI) is 34-35, which is a noncombustible material. Polyphenylene sulfide fiber needled felt not only has high temperature resistance, but also has unique corrosion resistance.

It is widely used in smelting, chemical, building materials, thermal power, waste incinerator, coal fired boiler and so on. It is a high - quality and high - temperature filter material. Our company selects polyphenylene sulfide fiber produced by the United States and Japan, according to other high temperature needling over felt production technology, specializing in the production of polyphenylene sulfide (PPS) needle felt, the product quality reached the level of similar products in developed countries.

The film coated needle filter felt produced by Shanghai Ke Ge filter material Co., Ltd. is a composite filter containing the diameter of polytetrafluoroethylene (PTFE) below 5um and coated on the surface of the needle filter felt.

The film features: the polytetrafluoroethylene film has a smooth surface and a chemical substance, which covers the surface of the ordinary filter material and plays the role of a disposable dust layer, and the dust is completely intercepted on the surface of the film to achieve surface filtration. Hydrophobicity makes the dust trapped on the surface easy to peel off, and at the same time, improves the service life of filter material. Compared with ordinary filter material, the advantages are:

The 1. film diameter between 0.23um, the filtration efficiency can reach more than 99.99, almost zero emissions. After dust removal, the porosity is not changed, and the efficiency of dust removal has been very high.

The pressure loss of 2. film filter material is higher than that of ordinary filter material when it is used. But after the operation, the pressure loss varies little with the increase of use time, and the pressure loss of ordinary filter material will increase with the use time.

3., ordinary filter media can easily enter the interior when used, and the more it accumulates, until the pore is blocked up, so it can not be used. With polytetrafluoroethylene film coated filter material, the filter dust is easily removed from the surface of the film. The effect of the dust cleaning is good, the cycle is long and the pressure strength of the dust removal is low, thus the service life of the filter material is improved, and the maintenance and maintenance work of the dust collector can be reduced significantly, the operation cost of the product is reduced, and the woven filter material is reduced. It is made of polytetrafluoroethylene membrane filter material and needle filter blanket. It is widely used in flue gas purification and dust removal, dust control and special recovery.

4., the membrane filter media also has good chemical stability, heat resistance and chemical corrosion resistance.
