Performance of ptfe protective clothing filter material
The fabrics and protective performance of medical protective clothing not only reflect the technical level of a country, but also reflect the strength of the country’s comprehensive national strength, and are also related to the lives, health and safety of the majority of medical workers and people. Therefore, excellent protective clothing It is very important. Here, the editor recommends PTFE protective clothing filter material to everyone.
Protective clothing is usually made of composite materials, such as polyester or polypropylene spun-laid nonwovens and breathable microporous films or other nonwovens, or spunlace nonwovens and breathable microporous films. Composite, or use wood paddle composite spunlace nonwoven fabric.
Polyethylene flash spinning nonwovens and spunbond/meltblown/spunbond (SMS) or spunbond/meltblown/meltblown/spunbond (SMMS) composite nonwovens and microporous films are currently widely used , and has been functionally finished with “three repellents and one resistance” (water repellent, blood repellent, alcohol repellent, and antistatic).
PTFE protective clothing filter material adopts a special processing technology and is a microporous film made by calendering, extrusion, biaxial stretching and other methods.
This kind of membrane has excellent breathability, corrosion resistance, aging resistance, high temperature resistance and other properties.
Three-dimensional mesh structure, no through holes.
The porosity and pore size distribution are important indicators for measuring films.
