With the development of modern industry, the processing and application technology of PTFE hydrophobic membrane has become increasingly mature. It is widely used in various industries, and the demand is increasing day by day, occupying an important position in the market of this industry.
Hydrophobic materials and porous hydrophobic membranes are different physical concepts. It is not appropriate to use a pure water contact angle greater than 90° as a criterion.
Hydrophobic membrane should refer to a porous membrane that will not leak pure water under the transmembrane pressure difference in a specific hydrophobic membrane separation process.
During the hydrophobic membrane separation process, organic or colloidal viscous pollutants are more easily adsorbed on the surface of the hydrophobic PVDF membrane than inorganic salts of calcium carbonate, reshaping the surface environment of the membrane material, making organic-inorganic composite pollutants It will accelerate the membrane distillation pollution process.
PTFE hydrophobic membrane has a microporous structure with staggered fibers. Through a biaxial stretching process and high-temperature heat setting treatment, the microporous structure is very stable and can effectively intercept dust particles.
The pore size of the material is small and the distribution is concentrated. Surface filtration is achieved to achieve a dust removal efficiency of 99.9%~99.999%. For some extremely small particles with a diameter of 0.1um-0.3um, it can better prevent fine dust from entering the filter material.
Can operate at a continuous operating temperature of 240°C and an instantaneous temperature of 260°C.
It is a ptfe hydrophobic membrane manufacturer that specializes 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.
