Production process
1. Raw material mixing: Mix polypropylene powder with additives in proportion to ensure material homogeneity.
2. High-temperature molding: heating and melting at about 150℃, and pressing into the initial embryo through the mold.
3. Cooling and shaping: use circulating water to cool indirectly and solidify the structure quickly.
4. Sintering process:
- Primary sintering: sintering at 700-750℃ to form a porous skeleton structure.
- Vacuum sintering: in the argon gas protected environment at 1000-1380℃ to eliminate pore cracks and enhance the densification.
5. Post-processing: cutting, polishing, testing (e.g. bubble point test, integrity test).
Product Advantages
1. chemical stability: acid and alkali resistance, organic solvents, suitable for corrosive media filtration.
2. High-precision filtration: the minimum precision can be up to 0.1μm, effectively retain microorganisms, colloids and so on.
3. High flow rate and low resistance: gradient pore design, large dirt-holding capacity and low differential pressure.
4. long life: can be regenerated by back-washing, high reuse rate.
5. Environmental protection and safety: no adhesive, in line with FDA and GMP standards, suitable for food and pharmaceutical industries.
