Polytetrafluoroethylene (PTFE) film has a smooth surface and is resistant to chemicals, which is laminated to the surface layer of ordinary filter material and plays the role of a disposable dust layer, and all the dust is retained on the surface of the film to realise surface filtration; and because of the smooth surface of the film, it has an excellent chemical stability, does not age, and is water-repellent, so that the dust retained on the surface can be easily flaked off, and at the same time, it improves the service life of the filter media. Compared with ordinary filter media, its advantages include: 1. 1. The pore size of the film is between 0.2-3μm, and the filtration efficiency can reach more than 99.99%, almost realising zero emission. No change in porosity after cleaning, dust removal efficiency is always high. 2. the pressure loss of the film filter media is higher than that of the common filter media when it is used at the beginning, but after it is put into operation, the pressure loss does not change much with the increase of the use time, while the pressure loss of the common filter media will be bigger and bigger with the prolongation of the time. 3. When ordinary filter media is in use, dust can easily enter into the inner part and accumulate more and more until the pores are blocked, which makes it impossible to continue to use. The use of PTFE film filter media, filter dust is easily removed from the membrane surface, good dust cleaning effect, long cycle, the use of lower pressure intensity of dust cleaning, thus improving the service life of the filter media, reducing the operating costs of the product.
