In recent years, ptfe hydrophobic membrane and its engineering applications have developed rapidly in our country, and many companies have launched Hydrophobic membrane products and various hydrophobic membrane process devices. These new membrane process technologies will promote the Chinese membrane industry to explore new application market areas.
Nanocellulose is derived from cellulose and is an emerging biomass nanomaterial. The modification methods that have been reported so far can be roughly divided into three categories: one is physical adsorption method, which mainly uses surfactants, oligomers or copolymers and other modifiers to change the surface properties of nanocellulose through physical adsorption. It has hydrophilic and hydrophobic properties and is a green and efficient modification method; the second is chemical methods, which mainly include silylation, alkanoylation, esterification modification, etc.; the third is polymer grafting method, which grafts nanocellulose on the surface. Branch hydrophobic polymer to improve hydrophobic properties.
Polytetrafluoroethylene bubble point film, also known as ptfe hydrophobic film, is generally made of polytetrafluoroethylene (ptfe) suspended powder as raw material, and 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 hydrophobic membrane produced has strong hydrophobicity, chemical resistance, waterproofness and low wind resistance, and can achieve high dust removal efficiency. For some poles with a diameter of 0.1um-0.3um For fine particles, the filtration level can reach H13-U16. Interested parties can enter the store to inquire and purchase! </p
