The coated filter bag production is based on a strict set of production techniques and is manufactured separately from warp and weft stretched PTFE microporous films. Use pressure and high temperature to fit different needle felt surfaces. When laminating with the thermoplastic fiber mat, we use special surface treatment technology to treat the surface of the mat first, and then overlay it with PTFE film. Non-thermoplastic fiber mats must first be surface chemically treated with Teflon and then laminated with PTFE. In addition, some special fibers need to be surface treated by special chemical methods in order to achieve the strongest bonding effect.
PTFE coated film filter bag (dust removal bag) has a smooth surface and is resistant to chemicals. It is coated on the surface of ordinary filter material, traps dust on the surface of the membrane, and achieves surface filtration. It has excellent chemical stability and is not aging. Drowning water improves the service life of filter bags.
