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
1. Chemical performance:
- Resistant to strong acid (sulfuric acid, hydrochloric acid), strong alkali (NaOH) and organic solvents (esters, ketones).
- No chemical adhesive to avoid secondary pollution.
2. Physical properties:
- High porosity (50-60%), high flow rate per unit area.
- Smooth surface, impurities are not easy to adhere to, easy to backwash regeneration.
3. Economy:
- 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
- Temperature limitation: Long-term use temperature should be ≤80℃ to avoid high temperature leading to structural deformation.
- Handling of viscous materials: Pre-filtration or addition of filter aids (such as diatomaceous earth) is required when encountering high-viscosity liquids.
- Regeneration method: Recommended 0.6MPa compressed air blowback or acid/alkali immersion cleaning.
