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, colloids and other substances are intercepted. Its filtration accuracy Far beyond filter paper, so he proposed the term ultrafiltration. In 1896, Martin produced the first artificial PTFE ultrafiltration membrane. In the 1960s, the concept of molecular weight was proposed, which was the beginning of modern ultrafiltration. In the 1970s, It was a period of rapid development in the 1980s and 1990s, and it began to mature after the 1990s.
my country’s research on this technology is relatively late. It was still in the research period in the 1970s and only entered the stage of industrial production and application in the late 1980s.
It is a manufacturer of polytetrafluoroethylene (ptfe) membrane environmentally friendly materials that specializes in R&D, production and sales.
