With the continuous development of China’s social economy, the concept of green environmental protection is increasingly valued by the public.
The country has also begun to introduce various new policies. How to make enterprises comply with green environmental protection has become an important issue for many traditional manufacturing enterprises.
Polytetrafluoroethylene filter membrane is made of polytetrafluoroethylene (PTFE) as raw material, which is expanded, calendered and biaxially stretched to form a microporous film.
PTFE material has excellent high temperature resistance, low temperature resistance, alkali resistance, anti-aging, anti-oxidation, hydrophobicity, non-toxicity, non-adhesion, chemical resistance and many other characteristics.
Therefore, it is widely used in air filtration, aviation, electronics, electrical appliances, chemicals, machinery, construction, textiles, medicine and many other fields.
?The polytetrafluoroethylene filter membrane has a three-dimensional mesh structure with no through holes.
The porosity and pore size distribution are important indicators for measuring PTFE membranes.
The porosity of polytetrafluoroethylene filter membrane is generally between 80% and 95%.
High porosity will increase ventilation; the pore size distribution is concentrated, indicating that the membrane pore size is uniform.
With special production technology, different pore sizes can be controlled for different materials to achieve high-efficiency filtration.
Usually, membrane thickness is not an indicator for evaluating PTFE filter membranes. If the thickness of the membrane is too thick, it will easily cause problems such as low air permeability and high operating pressure.
According to years of research and observation, film thickness basically does not affect the service life. The key is the composite strength, which is an important factor affecting the service life.
Suzhou is a manufacturer specializing in the production of polytetrafluoroethylene membrane materials. The company’s membrane materials 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 enterprises.
