The microporous filter membrane has various significant characteristics, which make it widely used in multiple fields. The following is a specific summary of the characteristics of microporous filter membranes:


1. Small and uniform aperture


The pore size of the microporous filter membrane is very small, reaching 0.1 μ m or even smaller, which can effectively intercept small particles and impurities.


The uniform distribution of pore size makes its filtering effect more stable and reliable.


2. Strong interception ability


Due to its small and uniform pore size, the microporous filter membrane has strong retention ability and can efficiently remove harmful substances such as suspended solids, bacteria, viruses, etc. from liquids or gases.


3. Light and thin texture, low resistance


The texture of microporous filter membrane is light and thin, with a thickness usually only half or thinner than ordinary filter media, which is beneficial for reducing resistance during the filtration process.


High porosity, with micropores accounting for about 80% of the total volume, further reduces filtration resistance and increases filtration rate.


4. Fast filtration speed


Compared with other filtration media with the same retention index, the filtration rate of microporous filter membrane is faster, sometimes even up to 40 times faster. This is due to its high clearance and low drag characteristics.


5. High separation efficiency


The microporous filter membrane can efficiently separate particles and substances in liquids or gases, ensuring that the filtered liquid or gas is purer.


Above all, microporous filter membranes have been widely used in various fields due to their small and uniform pore size, strong retention capacity, light and thin texture, fast filtration speed, high separation efficiency, no medium detachment, minimal impact on the properties of the liquid, low adsorption, diverse materials, high temperature and corrosion resistance, and easy use and maintenance.
