Polytetrafluoroethylene composite membrane for filtration field
The polytetrafluoroethylene composite membrane has a microporous structure with staggered fibers, which is formed by biaxial stretching. It is prepared through high-temperature heat setting process and has a very stable microporous structure.
The development and application of new fiber raw materials for filtration have promoted the progress of filtration technology, and the design and composition of the filter media structure are an important reason for the significant progress of today’s filtration technology. Due to its unique structural characteristics, nonwoven fabrics are increasingly used in the field of filtration, which greatly improves the filtration efficiency and dust holding capacity of the filtration system. The emergence of nonwoven fabrics and their unique properties have expanded the selection of filter materials and greatly improved the filtration effect.
PTFE composite membrane is a perfluorinated polymer obtained by polymerization. This material can be used for a long time in the range of -200℃ to 250℃. In its molecular structure, the carbon atom is surrounded by four fluorine atoms. Since the covalent radius of the fluorine atom (0.064nm) is larger than the radius of the hydrogen atom (0.028nm), the fluorine atoms can be arranged to surround the carbon chain, and Because fluorine atoms repel each other, the entire macromolecular chain does not have a zigzag shape like a hydrocarbon molecular chain.
