Cogos fine dust dust bag

The coated needle-punched filter felt produced by our factory is a composite filter material that reduces the pore size of polytetrafluoroethylene to less than 10% and covers the surface of the needle-punched filter felt. Features of this film-coated filter material: The surface of the polytetrafluoroethylene film is smooth and chemical. It is laminated to the surface of ordinary filter materials and functions as a disposable dust layer. All dust is trapped on the surface of the film to achieve surface filtration. And because the surface of the film is smooth, has excellent chemical stability, does not age, and is hydrophobic, the dust trapped on the surface can easily peel off, and at the same time, the service life of the filter material is increased. Compared with ordinary filter materials, its advantages are: The membrane pore size is between .3 and filtration efficiency can reach above .%, achieving almost zero emissions. The porosity does not change after cleaning, and the dust removal efficiency remains very high. ． When the membrane filter material is first used, the pressure loss is higher than that of ordinary filter material. However, after it is put into operation, the pressure loss does not change much with the increase of use time, while the pressure loss of ordinary filter material will increase with the extension of use time. getting bigger. ． When ordinary filter materials are used, dust can easily enter the interior and accumulate more and more until the pores are blocked, rendering it unusable. With the use of polytetrafluoroethylene coated filter media, the filtered dust is easily removed from the surface of the film, the cleaning effect is good, the cycle is long, and the cleaning pressure intensity is lower, thereby increasing the service life of the filter material and enabling It significantly reduces the maintenance workload of the dust collector and reduces the operating costs of the product. It is laminated with woven filter material and needle-punched filter felt to form a polytetrafluoroethylene-coated filter material, which is widely used in flue gas purification and dust removal. Management and special recycling and other fields. ． The film-coated filter material also has good chemical stability, heat resistance and chemical corrosion resistance.
