Polytetrafluoroethylene (PTFE) material has excellent high temperature resistance, alkali resistance, oxidation resistance, hydrophobicity and non-adhesion properties.
It is widely used in air purification, industrial dust removal, pharmaceutical fields, electronic appliances, clothing fields, etc.
Among them, membrane separation technology has the advantages of simple operation, small footprint, no phase change during the treatment process, no new pollutants produced, and good separation effect. It has been widely used in the field of water treatment in recent years.
With the development of science and technology and industrial production, issues such as energy, resources, and three waste management have received more attention.
In particular, the rapid development of high-tech fields such as biochemicals, fine chemicals, and energy materials has put forward higher requirements for the research and development of liquid and solid separation technologies. Micropore filtration technology with high separation accuracy and high operating efficiency and Microporous filter materials are attracting more and more attention.
PTFE air filter membrane has the characteristics of high porosity, low air permeability resistance, controllable pore size, easy cleaning and regeneration, and resistance to high temperature, high pressure, and chemical media corrosion.
? The PTFE air filtration membrane is prepared using a biaxial stretching process. It has a microporous structure with staggered fibers. It has high porosity, small and uniform pore size. Therefore, the PTFE air filtration membrane can be obtained with low resistance. Higher efficiency.
?Membrane materials are all produced using imported raw materials, with finer molecular weight, cleaner quality, and better uniformity. We have a complete set of domestically advanced production lines.
Advantages: (1) The porosity can reach 80%~90%. The porosity is high and the microporous structure is stable.
(2) Surface filtration mechanism, easy dust removal membrane with small pore size, small and uniform pore size.
(3)??PTFE material has strong hydrophobicity, low surface energy, and good non-adhesion. It is easy to remove dust accumulated on the surface of the material. Therefore, it can be washed with water to restore its performance and achieve repeated use, greatly extending its service life. .
