Suzhou New Material Technology Co., Ltd. is a fluorine material membrane that integrates the research, development, production and sales of PTFE air filtration membranes, PTFE bubble point membranes and other microporous membranes, PTFE membranes, Teflon membranes and coated filter materials. factory.
We have a professional polymer R&D team with strong R&D capabilities and multiple invention patent certificates and practical patent certificates.
And according to the user’s requirements, the key parameters of PTFE film technology such as speed ratio, pressure ratio, operating temperature, etc. can be optimized and combined. According to the ratio and pore-forming medium, the air permeability, thickness and The void ratio can be adjusted online to meet your different requirements.
The polytetrafluoroethylene membrane filtration (surface filtration) mode mainly has the following points: 1. Relying on the membrane on the surface of the filter material to filter dust particles 2. Dust particles will not enter the interior of the filter material 3. No need Establishing a powder cake 4. It can filter sub-micron dust particles 5. It can maintain good filtration effect under various system conditions. Polytetrafluoroethylene membrane filtration has very significant advantages: dust on the surface of the membrane is easy to fall off, and dust particles are not exposed. will accumulate on the base fabric. In addition, the film does not stick to water, so even wet dust can be handled.
The filtration mode of non-membrane filtration (depth filtration) mainly has the following points: 1. Dust is filtered inside the medium 2. Dust particles enter the medium and will penetrate 3. A powder cake needs to be established inside the medium 4. Unable to filter Extremely fine dust particles 5. The filtration efficiency is affected by different filter materials, dust particles and system aspects. This kind of non-membrane filtration can only remove the powder cake on the surface, and the internal dust particles are difficult to remove.
In addition, as dust particles continue to accumulate inside the medium, it will cause an increase in pressure drop or even blockage.
The accumulation of dust inside the media will cause leakage after cleaning.
