As an important filtering material, microporous membrane has various significant characteristics, which make it widely used in many fields such as scientific research, food testing, chemical engineering, nanotechnology, energy and environmental protection. The following are the main characteristics of microporous membranes:

Small and uniform aperture:

The pore size distribution of microporous membranes is very uniform, typically ranging from 0.1 micrometers to 10 micrometers. This uniform pore size distribution enables the microporous membrane to have a high screening effect during the filtration process, allowing for precise control of the particle size of the filtered material.

High interception capacity:

Due to its small and uniform pore size, microporous membranes can effectively trap suspended solids, bacteria, viruses, particles, and other impurities in water, with filtration accuracy meeting the requirements of sub high efficiency, high efficiency, and ultra high efficiency air filters.

Light and thin texture, low resistance:

The texture of microporous membrane is usually light and thin, with a thickness between 0.1~0.15mm, and a high porosity (microporous volume accounts for about 80% of the total volume). This makes the liquid medicine pass through the membrane with low resistance and fast filtration rate, which is 40 times faster than other filtration media with the same retention index.

It should be noted that although microporous membranes have many advantages, they also have some disadvantages, such as being prone to clogging, especially when dealing with liquids containing a large amount of suspended solids. In addition, some cellulose filter membranes may not have ideal stability under specific conditions. Therefore, when using microporous membranes, it is necessary to choose suitable materials and models according to specific application scenarios and requirements, and follow the correct usage and maintenance methods.
