The processing technology of disposable cloth mask filter membrane 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.
? Disposable cloth mask filter membrane has a porosity of more than 85%, 1.4 billion micropores per square centimeter, and a pore size range of 0.02um-1.5um.
The surface has a spider web-like microporous structure. Nanomasks produced using this material have the characteristics of high barrier efficiency, long service life, lightness and breathability, and are a new direction for the development of masks in the future.
? Products are widely used in various fields. With strong technical force and strict management system, the company ensures that everything focuses on the interests of users and provides users with high-tech, high-quality, high-performance, and high-level products.
