As we all know, filtration is mainly to remove unwanted particles to improve the accuracy of analysis.
However, if you choose an inappropriate filter, it will not only fail to achieve the purpose, but will become a source of pollution. Therefore, you must choose a suitable filter membrane. Here, the editor recommends PTFE gray membrane to everyone.
The filtration mechanism of polytetrafluoroethylene microporous membrane is surface filtration and can be used for a long time in the range of -200~250℃.
Due to the influence of the electron-withdrawing groups of fluorine atoms contained in the molecular structure, the polytetrafluoroethylene microporous membrane shows a high degree of chemical stability, is almost resistant to the intrusion of all acids and alkalis and other chemical substances, has outstanding non-stickiness and abnormal lubricity. As well as excellent electrical insulation properties, aging resistance and radiation resistance, minimal water absorption and other characteristics.
Widely used in petrochemical, machinery, electronics, electrical appliances, construction, textile and many other fields.
The filtration efficiency of ptfe gray membrane is 99.99995%, and the transmittance is 0.00005%.
In comparison, this means that if a gas containing 1 million dust (particles) is filtered, as many as 1.3 million particles will pass through the former, while only 5 particles will pass through the latter.
It can be seen that the filtration efficiency of ultra-fine glass fiber filter paper is very outstanding.
It is a fluorine material film manufacturer integrating production, sales and customization.
