How about using imported spunbond non-woven fabrics?
Imported spunbond non-woven fabric is very easy to use! The production process of imported non-woven fabrics is to extrude and stretch the polymer to form continuous filaments, then lay the filaments into a web…
Is the clean room FFU filter membrane symmetrical?
Asymmetrical, the clean room FFU filter membrane is an asymmetric membrane, and the micropore sizes are different on the front and back sides of the membrane. The cross-sectional micropore size of the membrane …
What is the working principle of ptfe ultrafiltration membrane?
The work of ptfe ultrafiltration membrane is mainly based on the screening mechanism, and water purification is carried out based on the working pressure and the pore size of the membrane. Taking hollow fiber a…
What is the structure of clean room FFU filter membrane?
The clean room FFU filter membrane has a node-fine fiber structure, forming hundreds of millions of micropores per unit area, which can effectively intercept dust in the air. It is very suitable for air purific…
Why are imported spunbond non-woven fabrics used the most?
An important reason for the rapid development of imported spunbond non-woven fabrics is that it uses synthetic polymers as raw materials. This method uses the principle of chemical fiber spinning. During the po…
Why are imported spunbond non-woven fabrics so expensive and what are their advantages?
This mainly depends on its production process. The production process of imported non-woven fabrics is to extrude and stretch the polymer to form continuous filaments. The filaments are laid into a web, and the…

What is the origin of ptfe ultrafiltration membrane?
Ultrafiltration originated in 1748. Schmidt used cotton membrane or Lu membrane to filter solutions. When a certain pressure is applied, the solution (water) passes through the membrane, while proteins, colloid…
What kind of technology is ptfe ultrafiltration membrane?
Ultrafiltration is a pressurized membrane separation technology, that is, under a certain pressure, small molecular solutes and solvents are allowed to pass through a special membrane with a certain pore size, …
Why are clean room FFU filter membranes used in purification project construction?
We all know that when a clean room (CLEANROOM) is carrying out purification engineering construction, it needs to use many filtration equipment, and the core of these filtration equipment is almost all made of …
