The Teflon air filtration membrane produced and developed by the company has excellent high temperature resistance, high temperature resistance, low temperature resistance, alkali resistance, anti-aging, anti-oxidation, electrically insulated wire, hydrophobicity, non-toxic, high lubrication, and non-stick Attachment, weather resistance, chemical resistance and many other features.
Therefore it is widely used in air filtration, chemical industry and many other fields.
?There are two main methods for preparing Teflon air filtration membranes that have been reported so far.
One is to add the pore-forming agent NaCl to ptfe, then make the ptfe into a film, and then remove the NaCl by heating and washing with water. The vacancies left by the NaCl form pores. The microporous film made by this method has the smallest pore size. is 0.1μm.
The second is the mechanical stretching method. The microporous film made by the modified method has a special structure of island-like “knots” connected by microfibers. It is currently the main method for preparing PTFE microporous films.
? is a high-tech enterprise focusing on R&D, production and sales. We have the characteristics of “uniform and stable, efficient and low resistance, long life, customizable, easy cleaning and maintenance” in various fields, and are favored by many enterprises. Accepted and loved.
