Film-covered dust bag coated film filter is expanded polytetrafluoroethylene (e-PTFE)
Microporous membranes are composited on various dust bag substrates using special processes.
Film dust bag filter
It not only maintains the high chemical resistance inherent in PTFE, low coefficient of friction, high and low temperature resistance, anti-aging, etc.
Another general dust bag filter material has no comparable permeability, waterproof properties. Compared with ordinary filter media, its advantages are:
Film aperture between 0.23um, filtration efficiency can reach 99.99
More than %, almost
Zero emissions. After the dust is removed, the porosity is not changed and the dust removal efficiency is always high. The film filter also has good chemical stability, heat resistance and chemical resistance.
The film-covered dustbag is a tough and flexible fiber structure that is compounded with a strong substrate.
Therefore, there is sufficient mechanical strength, combined with excellent deashing, reducing the dust removal intensity,
With low and stable pressure loss, it can be used for a long period of time, prolonging the life of the film dust bag filter bag.
Film-covered dust bag characteristics: large air permeability, low resistance, good filtration efficiency, large dust holding capacity, high dust removal rate is the best filter material for bacteria removal and dust removal. Microfiltration: PET, PP
Non-woven fabrics
After coating, filters and filters can be used in chemical, pharmaceutical, electronics and other industries. They can not only filter micro-particles and isolate bacteria, but also maintain high filtration efficiency and low flow and smooth resistance.
