PTFE microporous membrane material has changed the filtration mechanism of ordinary filter materials, from the deep filtration mechanism of ordinary filter materials to a surface filtration mechanism.
The mechanism of surface filtration is the same as that of powder layer filtration, mainly relying on micropore screening.
Because the pore size of the membrane is very small, it can retain most of the dust on the surface of the membrane, completing the gas-solid separation process.
?This process is different from the separation process of general filter materials. The dust does not penetrate deep into the fibers supporting the filter materials.
The advantage is: a thin layer of dust with good air permeability can be formed on the surface of the PTFE microporous membrane at the beginning of the filter cartridge operation, which can not only ensure high dust removal efficiency, but also maintain low operating resistance.
It is also easy to clean.
The peeling off of the dust layer on the surface of the filter cartridge membrane is very different from that of ordinary filter cartridges. The dust layer on the composite filter cartridge is very easy to peel off, and sometimes the dust will fall off before the dust cleaning mechanism is activated.
