Product features
- Temperature resistance: continuous working temperature up to 80℃, short-term can withstand 100℃.
- Mechanical properties: compressive strength 0.3-0.6MPa, good toughness, not easy to break.
- Reusable: support physical backblowing (0.6MPa compressed air) or chemical cleaning (acid/alkali soaking) regeneration.
Production Process of Sintered PE cap
1. Raw material processing
- UHMWPE powder is selected and mixed with plasticizers, stabilizers and other auxiliary materials.
2. Mold filling and pre-pressing
- The mixture is filled into the mold and pre-pressurized mechanically to form a preliminary shape.
3. High temperature sintering molding
- Heating in three stages (low-temperature pre-molding → medium-temperature sintering → high-temperature strengthening), the temperature is controlled at 110-130 ℃ (lower than the melting point of PE), so that the powder particles are fused and bonded to form a porous structure.
4. Post-treatment and processing
- After demolding, cut to the required length and install the joints (e.g. M20, M30 thread).
5. Quality Inspection
- Conduct bubble uniformity test, compressive strength test and chemical compatibility test.
Advantages of Sintered PE cap
1. High efficiency filtration: high porosity (50%) and uniform pore size design, high flow rate and not easy to be clogged.
2. Economical and durable: can be repeatedly cleaned and regenerated, life expectancy of 1-3 years, the cost is lower than the ceramic cartridge.
3. Safe and environmentally friendly: non-toxic and odorless, in line with the hygiene standards of the food and pharmaceutical industry.
4. Strong adaptability: support customized shaped structure (piece, tube, rod, cap, etc.) and special precision requirements.
