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 laminate it with PTFE film. Non-thermoplastic fiber mats must first undergo surface chemistry, Teflon treatment, and then be 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. From a PTFE film having a pore diameter of 0.1-3.5 μ m, a porosity of 75-90% porous. Such a high microporous porosity is sufficient to allow a large amount of dense water vapor to pass freely, because minute molecules of water vapor can freely diffuse through the gaps of the film. However, vablue 's PTFE is extremely hydrophobic and water cannot penetrate the microporous membrane. Because PTFE has excellent corrosion resistance to any chemical, PTFE membranes can be used in a variety of chemical production processes. Keda's production can be customized according to the user-supplied specifications or drawings processing laminated film bag . Details login: http://
