Polytetrafluoroethylene is a material that has excellent chemical resistance and is resistant to all chemicals. It is known as the king of plastics.
At present, a series of filter materials made of PTFE liquid filter membrane are widely used in many fields such as garbage incineration and high-sulfur coal dust removal.
In the 21st century, the global environmental protection industry has begun to enter a stage of rapid development, gradually becoming an important force supporting the growth of industrial economic benefits, and becoming an important goal and key for many countries to innovate and adjust their industrial structures.
At present, my country’s environmental protection industry accounts for less than 3% of the total economy, and there is huge market development space for water filtration materials.
With the upgrading of consumption, people’s pursuit of healthy life and water quality requirements are getting higher and higher. As domestic household water purification technology continues to mature, household water purifiers will be more and more widely used in the daily life of ordinary families. Become a must-have household appliance.
There are two main methods for preparing ptfe liquid filtration membranes.
One is to add the pore-forming agent NaCl to PTFE, then make the PTFE into a film, and then remove the NaCl by heating and washing with water. The vacancies left by the NaCl form pores. The microporous film made by this method has the smallest pore size. is 0.1μm.
The second is the mechanical stretching method. The microporous film made by the modified method has a special structure of island-like “knots” connected by microfibers. It is currently the main method for preparing PTFE microporous films.
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. .
