As a new type of composite filter bag, polyester + PTFE filter bag innovatively combines polyester and polytetrafluoroethylene (PTFE). With the complementary performance between the materials, it exhibits excellent filtration efficiency and plays an important role in many fields.
Description
The filter material is made of 100% filament polyester fiber, which is processed by needle punching, singeing, heat setting, calendaring, polytetrafluoroethylene film coating, anti-static and other processes, and then the polyester needle felt coated with polytetrafluoroethylene film is sewn into filter bags.
- High-efficiency filtration
This filter bag not only has outstanding filtration efficiency, but can also effectively remove suspended particles, organic pollutants, ammonia and other harmful substances in indoor and outdoor air, and can also block heavy metal pollution; at the same time, it has excellent sealing properties, which can reduce dust splashing, prevent pollutants and microbial penetration, and even block some harmful gases, comprehensively improving the quality of the filtered air.
- Durability
It has good thickness uniformity, strong wear resistance, excellent tear resistance, and can resist large pressure differences and high temperature deformation (although there are temperature resistance limitations, it is stable and reliable within the applicable range).
- Cost reduction and efficiency improvement
Compared with traditional filtration methods, polyurethane + PTFE composite filter bags have good cost performance and low maintenance costs.
