Practical effect of the PTFE coated needle felt powder bag
PTFE coated needle felt powder collector bag, which is formed by laminating the microporous PTFE film through a special thermal coating process, the needle felt and the film is smooth, the surface is smooth, the powder is easy to peel, the powder is thoroughly cleaned, and the powder is reduced in the filter bag. Possibility of compaction after forming a layer of fabric powder on the surface. The coated filter material not only maintains the high chemical stability, low coefficient of friction, high and low-temperature resistance and ageing resistance inherent in PTFE, but also resists small particles and has an unrivalled permeability of the overall coated filter material., waterproof and other features. It has an excellent anti-condensation function, especially for the environment with high concentration and high humidity of gas containing dust, high adhesion powder, and high emission requirements.
Using the film dust collector bag, the powder cannot penetrate the filter material, but the surface is filtered, whether coarse or fine powder, all deposited on the filter material surface of the filmed polyester needle felt dust collector bag, i.e. the filter is retained by the pore size of the film itself, not. In the initial filtration period, effective filtration is used from the beginning of use, and filtration takes place almost 100% of the time.
The fabric bag of felt powder collector with membrane needle is a new type of post-processing technology that is more advanced than the filter bag after the waterproof and oil-repellent treatment. The surface coating of the filter material not only solves the problems of preventing condensation and the paste bag but is also very large. The filtration effect of the dust collector bag has improved and now many environmental protection requirements for ultra-low emission filtration occasions generally require the dust collector bag to be coated with a film. In some places with high humidity, using a bag with a film dust collector will have a better effect than the bag with a conventional oil proof and water repellent dust collector.
