There are two main methods for preparing ptfe gray membrane.
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.
Ptfe gray membrane material has a microporous structure with staggered fibers, achieving surface filtration and dust removal efficiency reaching 99.9%~99.999% for some extremely small particles with a diameter of 0.1um-0.3um.
The porosity can reach 80%~90%, it has strong hydrophobicity, low surface energy, and good non-adhesive ability. It can effectively remove dust accumulated on the surface. It can restore the performance by washing with water or backflushing, and greatly extends the service life.
