PTFE bubble point membrane composite material is a layer of polytetrafluoroethylene (PTFE) compounded on the surface of ordinary filter materials. ) thin film is a new type of material. At present, this material has a wide range of applications.
There are many types of membranes, which are classified according to the separation mechanism, including reaction membranes, ion exchange membranes, permeable membranes, etc.; according to the properties of the membrane, there are natural membranes (biological membranes) and synthetic membranes (organic membranes and inorganic membranes); according to membrane The structural types are classified into flat type, tube type, spiral type and hollow fiber type. Since the 1980s, membrane bioreactors have received more and more attention and become one of the hot spots of research. At present, this technology has been used in more than ten countries including the United States, Germany, France and Egypt, with scales ranging from 6m3/d to 13,000m3/d.
Polytetrafluoroethylene bubble point film, also known as ptfe bubble point film, is generally made of polytetrafluoroethylene suspended powder as raw material, which is expanded and stretched to form a microporous film. It has a fibrillar microporous structure, the porosity can reach more than 88%, there are 1.4 billion micropores per square centimeter, and the pore diameter ranges from 0.1μm to 0.5μm. Generally, this film is coated on various fabrics and substrates using special processes to become a new filter material.
The ptfe biaxially stretched film produced has strong hydrophobicity, chemical resistance, waterproofness and low wind resistance, and can obtain high dust removal efficiency. For some diameters of 0.1um-0.3um of extremely fine particles, and the filtration level can reach H13-U16. In addition, the biaxially stretched film can undoubtedly achieve ultra-low emissions in intercepting various types of dust generated during the company’s production process, and it fully complies with current environmental protection standards.
