For filter cartridges, their precision and material determine their application fields and filtration effects. Different filtration precisions are suitable for different occasions and achieve different filtration results. Meanwhile, the material has a greater impact on the filtration strength and whether it can be applied in high-end fields.
Now, let's take a detailed look at the classification and related characteristics of micro-porous pleated membrane filter cartridge in terms of precision and material.
Micro-porous pleated filter cartridges are mainly divided into two categories in terms of precision: low precision and high precision.
Low-precision micro-porous pleated filter cartridges are mainly concentrated at 1 micron and 5 microns. These filter cartridges are mainly used in water treatment and play a pre-filtration role in water filtration, effectively removing impurities and suspended particles from water.
High-precision micro-porous pleated filter cartridges are mainly represented by 0.1 micron and 0.22 micron. They are mainly used in occasions with high filtration requirements, such as in sterile environments in the medical industry, where they play a role in sterilization.
Regarding the materials of micro-porous folding filter cartridge, they can be classified into four aspects, as follows:
Polypropylene material: This type of filter cartridge is mostly used in water filtration. It is relatively inexpensive and has good chemical compatibility, making it suitable for common water treatment pre-filtration.
Polytetrafluoroethylene material (PTFE): It is mainly used in extreme chemical environments. Its properties of high temperature resistance and resistance to strong acids and alkalis make it stand out in extreme conditions.
Polyvinylidene fluoride material (PVDF): It is mostly used in sterilization filtration. The medical industry's sterile environments cannot do without its performance.
Stainless steel or metal materials: These materials make the micro-porous pleated filter cartridge more resistant to high temperatures and high pressures. They can be repeatedly washed and used, and are particularly effective in metallurgical and other working conditions.
