Facing the increasingly serious environmental pollution problem, indoor environmental management and protection can be said to be the last line of defense for human health. In order to better protect this line of defense, people have developed a material, which is Teflon. Air filter membrane.
Teflon (Teflon) coating is a special high-performance coating (paint) that combines heat resistance, chemical inertness, excellent insulation stability and low friction, and has features that other coatings cannot compete with. Comprehensive advantages.
Its flexible applicability makes it widely used in: tableware, molds, cookware, home appliances, furniture, technology, automobiles, machinery, medicine, etc.
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.
It is an environmentally friendly material manufacturer specializing in R&D, production and sales of Teflon air filtration membranes.
Our company is different from other manufacturers.
Our company can customize according to user’s requirements.
