PE/PA sintered filter cartridges are made of polyethylene (PE) and polyamide (PA) polymer materials through a special sintering process. They combine high strength, corrosion resistance, and precise filtration performance, effectively intercepting particulate impurities in fluids and providing stable and reliable filtration solutions for multiple industries.
The PE sintered filter element is made by sintering ultra-high molecular weight polyethylene. It features a compact, sturdy structure, light weight, and the ability to withstand high filtration pressure. It is non-toxic and odorless, and has excellent corrosion resistance to acids, alkalis, and solvents.
Fluid Inlet: Liquids or gases containing impurities flow into the filtration area from one end or the outside of the cartridge.
Layered Interception Filtration:
Outer Primary Filtration: The large - pore structure of the outer layer of the cartridge first intercepts large - sized impurities, such as sand and rust.
Inner Fine Filtration: The small - pore structure of the inner layer further retains tiny particles, colloids, and suspended solids, achieving fine filtration.
Discharge of Clean Fluid: The clean fluid after double - layer filtration from the inside or the other end of the cartridge meets the usage requirements.
Maintenance and Replacement: When the pressure difference before and after the cartridge reaches the set value (e.g., 0.15MPa) or the flow rate significantly decreases, it can be cleaned by backwashing, chemical cleaning, etc. If the performance cannot be restored after cleaning, the cartridge needs to be replaced.

Which chemical substances can PE/PA sintered filter cartridges resist?
They can resist common acid - base solutions such as hydrochloric acid, sulfuric acid, and sodium hydroxide, as well as organic solvents such as ethanol and acetone. However, prolonged contact with strong oxidizing substances (such as concentrated nitric acid) should be avoided.
What are the cleaning methods for the cartridges?
They can be cleaned by backwashing with clean water, ultrasonic cleaning, or soaking in mild chemical agents. After cleaning, rinse thoroughly with clean water to ensure no residue.
How to select the appropriate filter cartridge accuracy?
Select the corresponding accuracy according to the particle size of impurities in the fluid and subsequent process requirements. For example, 1 - 5μm is recommended for the electronics industry, and 5 - 20μm for the food industry.
PE/PA sintered filter cartridges have become an ideal choice for fluid purification in multiple industries, thanks to the unique advantages of polymer materials, stable and reliable filtration performance, and high cost - performance. Whether in complex chemical production environments or in the electronics industry with extremely high purity requirements, efficient filtration can be achieved through customized selection and scientific maintenance. In the future, with the development of polymer material technology, PE/PA sintered filter cartridges will continue to optimize their performance and provide better filtration solutions for more fields.
