Ultrafiltration is a membrane separation process that uses sieving as the separation principle and pressure as the driving force. The filtration accuracy is in the range of 0.005-0.01μm, which can effectively r…

If you want the fresh air system to maintain a good filtration effect, you need to understand the HEPA filter. If there are no specific instructions, it cannot be washed. In the case of severe indoor air pollut…

Ultrafiltration membranes are divided into plate and frame type (plate type), hollow fiber type, nanomembrane surface ultrafiltration membrane, ptfe tubular ultrafiltration membrane, roll type and other structu…

Proton exchange membrane (PEM) is the core component of proton exchange membrane fuel cell (PEMFC). Its quality directly affects the service life of the battery. The proton exchange membrane is essentially a se…

The key role of the HEPA filter in air purification is to filter PM2.5 and other harmful gases. It can also capture mold, small bacteria, viruses, and filter second-hand smoke and pollutants in the air. Harmful…

Modify expanded polytetrafluoroethylene membrane with functional molecules to give it special functions such as catalysis, bacteria resistance, transmission, and proton exchange. It not only broadens It has est…

At present, there are mainly five types of ultrafiltration membrane devices commonly used in industry: plate and frame type, tube type, spiral wound type, hollow fiber type,ptfe Tubular ultrafiltration membrane…
