If the water purifier uses PTFE corrosion-resistant filter membrane as the filter, the quality of the filtered water will be greatly improved, because when the particles in the water are larger than the pore si…

Ultrafiltration membranes mainly include cellulose and its derivatives, polycarbonate, polyvinyl chloride, polyvinylidene fluoride, etc. Its filtration process will not undergo chemical changes or phase changes…

As the country pays more and more attention to environmental protection, all walks of life are paying more and more attention to sewage treatment. The focus of the water treatment industry is still on the role …

Ultrafiltration membranes have a wide range of industrial applications and have become one of the new chemical unit operations. Used in separation, concentration and purification of biological products, pharmac…

Yes, the diameter of the virus is very small, but it has no cell wall itself and cannot exist alone when exposed to the air. In order for the virus to spread (survive) in the air, it must be parasitic in a cell…

The ptfe reusable mask filter membrane is a purely physical barrier and does not rely on static electricity. When the user inhales, the pore size of 100~200 nanometers will physically filter PM2.5 to PM0.3 and …

Domestic fresh air purification systems generally use H11 high-efficiency HEPA filters to filter 0.3 micron particles with a filtration efficiency of more than 95%, which is similar to the interception and bloc…

In addition to ventilation, the most important function of the fresh air system is to filter pollutants in the air. Therefore, the filter of the fresh air system is the most important part of the entire system.…

The pore size of the ptfe industrial fresh air filter material is small and the distribution is concentrated, which can better prevent fine dust from entering the filter material, just like a first layer of art…
