Imported wet-laid polyester non-woven fabrics are made of polyester (pet) fiber as the main raw material. Each fiber is independent and can prevent it from becoming brittle or deformed even at low temperatures …

The transmembrane pressure difference required for membrane separation is generally 0.5 to 2.0MPa, which is 0.5 to 3MPa lower than the pressure difference necessary to achieve the same permeability energy with …

PTFE liquid filtration membrane uses the difference in selective permeability performance of each component in the mixture to separate two-component or multi-component mixed gases or liquids using external ener…

KN95 masks and N95 masks are used in non-medical settings and are used to protect against various aerosol particles suspended in the air, including dust, smoke, fog and pathogenic microorganisms (such as bacter…

For liquid filtration, it is better to use PTFE liquid filter membrane, which uses polytetrafluoroethylene (PTFE) suspended powder as raw material. Prepared using unique biaxial stretching technology. It has a …

General masks are made of non-woven materials with large fiber diameters (between 1000 nanometers and 5000 nanometers), and the protective effect is obviously weaker than the kn95 mask filter membrane. This mem…

How are N95 masks regulated? N95 masks are the American NIOSH dust mask standard, and the production standards are consistent with domestic KN95 (the protection levels of the two produced masks are exactly the …

Clean room FFU filter membrane is made by special processes such as biaxial stretching. The clean room filter membrane has a fibrillar microporous structure, the porosity can reach more than 85%, there are 1.4 …

The new type of pneumonia epidemic is fierce. With most parts of the country fully resuming work, masks have become a necessity. However, most masks are now made of melt-blown non-woven fabrics, which rely on t…
