Production Process of PE Filter Cartridge
1. Raw material treatment: screening UHMWPE powder and removing impurities.
2. Mold assembly: silicone oil is applied to both internal and external molds to ensure smooth surface after sintering.
3. Sintering molding: high temperature (250-300℃) sintering for 5-6 hours to form a porous structure.
4. Cooling and demolding: natural cooling and demolding to avoid deformation.
5. Trimming and testing: cut to standard length and conduct bubble uniformity test.
6. Packing and storage: sealed packaging to avoid contamination.
Advantages of PE Filter Cartridge
• Resistant to strong acid (sulfuric acid, hydrochloric acid), strong alkali (NaOH) and organic solvents (esters, ketones).
• No chemical adhesive to avoid secondary pollution.
• High porosity (50-60%), high flow rate per unit area.
• Smooth surface, impurities are not easy to adhere to, easy to backwash regeneration.
• The cost is lower than metal cartridge, long service life (can be repeated cleaning).
• Support non-standard customization, suitable for a variety of equipment.

Precautions
Frequently Asked Questions (FAQ)
For long-term use, the temperature should be kept at or below 80℃. It can withstand short-term exposure up to 130℃ for steam sterilization, but caution must be taken as high temperatures can easily cause structural deformation.
Regeneration can be achieved through either 0.6MPa compressed air blowback or acid/alkali immersion cleaning, depending on the chemical properties of the contaminants.
PE filter cartridges offer excellent chemical resistance. They are highly resistant to strong acids (such as sulfuric and hydrochloric acid), strong alkalis (like NaOH), and various organic solvents (including esters and ketones).
For high-viscosity fluids, it is recommended to perform a pre-filtration stage or add appropriate filter aids, such as diatomaceous earth, to prevent premature clogging and maintain performance.
Yes. While standard lengths range from 10 to 40 inches, customization is supported up to 1500mm in length, 10-120mm in diameter, and high-accuracy requirements down to 0.3μm.
