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.
The advantages of the membrane filter bag:
Close to zero emissions, to achieve the most stringent environmental standards.
Dust cleaning is good, can provide higher ventilation, or can reduce the pressure difference.
With higher air-to-cloth ratio, smaller dust collectors can be designed, and the energy consumption can be reduced when the pressure difference is reduced.
The life of the coated filter bag is prolonged, the number of cleanings is reduced, and the equipment maintenance cost is reduced.
The reduction of investment and operating costs will lead to better economic benefits for users.
