The difference between ptfe coated filter material and ordinary filter material

The essential difference between ptfe coated filter media and ordinary filter media in terms of filtration principle: Ordinary filter media are traditional needle-punched felt, woven filter media, etc.

The working principle is the so-called “depth filtration” technology, that is, through the collection of filter material fibers, a “primary dust layer” (i.e. powder cake) is first formed on the surface of the filter material, and then this layer of powder cake is used to filter subsequent dust. dust.

In the early stage of reuse, due to the large gaps in the filter material itself, some dust will pass through the filter material and be emitted. Only when the powder cake is formed, the filtration process really begins. After continued use, the dust on the surface of the filter material will gradually penetrate into In the filter material, the gaps in the filter material will be blocked, which will continuously increase the operating resistance of the equipment until the filter must be replaced.

PTFE coated filter material refers to a new type of filter material formed by compounding a layer of polytetrafluoroethylene (ptfe) film on the surface of ordinary filter material.

This layer of film is equivalent to a “primary dust layer”. Material exchange is carried out on the surface of the membrane, and effective filtration can be carried out from the beginning of use.

The unique three-dimensional network structure of PTFE film makes it impossible for dust to pass through, so there is no risk of pore clogging.

This filtration method of ptfe coated filter material is called “surface filtration”.

This kind of filter material can not only achieve near-zero emissions, but also due to the non-stickiness of the film and the small friction coefficient, the powder cake will automatically fall off, ensuring long-term stability of the equipment resistance, thus giving full play to the advantages of the bag dust collector. , is an ideal filter material choice.
