The core processing technology of ptfe nano mask cloth is extrusion, calendering, stretching and sintering. A special extruder is used to extrude rod-shaped or strip-shaped polytetrafluoroethylene tape, which is rolled into a very thin film on a calender. The flakes are dried to remove the additives and then biaxially stretched on a stretching machine.
The surface of the ptfe nano mask cloth is composed of 100~200 nanofibers staggered into holes. After the fiber diameter is reduced to the nanometer level, the surface area increases, the pore size becomes smaller, and the pore volume increases, which can effectively block PM2. 5.
It also has a fibrillar microporous structure with a porosity of more than 88%. There are 1.4 billion micropores per square centimeter and the pore diameter ranges from 0.1μm to 0.5μm. This film is coated on each surface using a special process. On fabrics and substrates, it can become a new type of filter material.
The company has always implemented the tenet of “quality first, reputation first”. We have a complete service system, caring before sales, attentiveness during sales, and assured after-sales! The company can provide samples and arrange sales personnel for door-to-door service if there are other requirements.
