We all know that some precision machinery, pharmaceuticals, hospitals and other fields have extremely strict requirements on indoor temperature, humidity, and cleanliness. In order to ensure the requirements, the material FFU dust-free workshop purification membrane must be used.
Only by controlling the pressure difference in the purification area and ensuring reasonable air flow organization can purification and process requirements be met.
For example, a clean factory must maintain a certain positive pressure to prevent unpurified outside air from entering the purification area to ensure the cleanliness level; and by controlling the different pressure differences in each purification area, the role of purification partitions can be achieved. GMP requires that the pressure difference in areas with different purification levels should be controlled to not be less than +5Pa.
FFU dust-free workshop purification membrane refers to a microporous film made of polytetrafluoroethylene as raw material, using special processing technology, and through calendering, extrusion, biaxial stretching and other methods.
This kind of membrane has excellent breathability, corrosion resistance, aging resistance, high temperature resistance and other properties.
According to the usage requirements, the pore diameter can be between 0.1-10um, the thickness can be between 2-100um, the porosity can reach 50%–80%, and there are up to hundreds of millions of micropores per square centimeter.
Suzhou New Material Technology Co., Ltd. is a fluorine material film manufacturer that integrates the R&D, production and sales of PTFE air filtration membranes, PTFE bubble point membranes, FFU dust-free workshop purification membranes, Teflon membranes and coated filter materials.
The company has advanced PTFE film production lines, lamination and composite production lines, which are at the domestic advanced level.
