The filtration industry recommends ptfe liquid filtration membrane
What people usually call ptfe is polytetrafluoroethylene, which can also be called ptfe liquid filter membrane. It is one of the more high-end varieties of bag filter materials at present, and it is also an indispensable one in the modern filtration industry. Important material.
At present, the scale of the water filtration industry continues to expand. There are already more than 3,000 water purification product manufacturers in our country. This number will increase in the past two years, but this scale is based on low quality. .
At this stage, the barriers to entry for the water purification industry are low. Many companies do not have product research and development and technological innovation capabilities. Their products are highly homogeneous. They do not have modern testing equipment, their product quality control capabilities are limited, and their after-sales services cannot keep up.
Therefore, the development and manufacturing of functional, heterogeneous, and high-quality filter elements is particularly important.
The transverse stretching stage is a key step in controlling the microporous structure and thickness of PTFE liquid filtration membrane.
During the transverse stretching process, each part of the film along the transverse stretching direction is stretched unevenly, and transverse stretching is an uneven stretching process.
Compared with the two sides of the film, the stretch in the middle part is relatively small. Uneven transverse stretching causes the middle region of the film in the transverse stretching direction to have small pores and low porosity, while the two sides have large pores and porosity.
The difference in microporous structure in the transverse stretching direction of the film will affect the waterproof and moisture-permeable properties of the film and its laminated fabric.
We are a manufacturer specializing in the production of ptfe liquid filtration membrane materials. In the field of industrial sewage treatment, we have the characteristics of “uniform and stable, high efficiency and low resistance, long life, customizable, easy cleaning and maintenance” and are accepted and loved by the majority of enterprises. .
