PTFE high temperature resistant filtration membrane is the core component in the membrane distillation process. The development of a membrane distillation method with super hydrophobicity, anti-pollution and long-term operation stability is the core issue for the industrial application of this technology.
The main component of smog is fine particles floating in the atmosphere, of which PM2.5 is the most harmful.
PM2.5 refers to solid particles in the atmosphere with a diameter less than or equal to 2.5 μm. Due to its tiny characteristics, it can smoothly enter the human lungs and then enter the bronchus, interfering with the gas exchange in the lungs and even inducing other diseases.
PTFE high temperature resistant filter membrane has excellent waterproof, moisture permeable, air permeable, corrosion resistance, aging resistance, high temperature resistance and other properties.
According to the usage requirements, the pore size of this microporous membrane can be between 0.1-1um, the thickness can be between 10-100um, the porosity can reach 50%-90%, and there are hundreds of millions of micropores per square centimeter.
Since the pore size of the microporous membrane is much larger than that of water vapor molecules, and polytetrafluoroethylene (PTFE) is a hydrophobic material, water droplets cannot penetrate the micropores, so it has good moisture permeability, air permeability and waterproofness, and the microporous membrane is resistant to water pressure. Up to 0.1MPa.
PTFE film manufacturer specializes in the production of PTFE high-temperature resistant filter membranes. It has a full set of advanced production equipment and technology, and also has an advanced clean room and an independent composite slitting workshop to ensure the production quality of PTFE membrane; the product materials produced They all use imported raw materials, with high uniformity, stable performance, good air permeability, and the filtration efficiency can reach 99.999995%! It can basically meet the filtration efficiency grade requirements of sub-high efficiency, high efficiency and ultra high efficiency filters.
