With the rapid progress of modern industry, the development of PTFE ultrafiltration membrane has provided many effective help to many enterprises and also promoted the development of some high technologies.
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 ultrafiltration membrane. In the 1960s, the concept of molecular weight was proposed, which was the beginning of modern ultrafiltration. In the 1970s and The 1980s was a period of rapid development, and it began to mature after the 1990s.
my country’s research on PTFE ultrafiltration membrane technology was relatively late. It was still in the research period in the 1970s and only entered the industrial production and application stage in the late 1980s.
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, while large molecular solutes cannot pass through and remain on one side of the membrane. , thereby partially purifying macromolecular substances.
Ultrafiltration is one of the membrane separation technologies driven by pressure.
The purpose is to separate large molecules and small molecules.
It is a ptfe ultrafiltration membrane manufacturer specializing in R&D, production and sales.
The materials of the products produced by our company are all imported raw materials, with high uniformity, stable performance and good breathability.
It also has high filtration efficiency and can meet the filtration efficiency level requirements of sub-high efficiency, high efficiency and ultra high efficiency filters.
We have a complete service system, with thoughtfulness before sales, attentiveness during sales, and peace of mind after sales! The company can provide samples and arrange sales personnel for door-to-door service if there are other requirements.
You are welcome to come to the company for inspection or enter the store to consult us at any time.
