Product Features
Resistant to strong acids, alkalis and organic solvents (except strong oxidizing agents such as concentrated sulfuric acid).
Continuous working temperature up to 80℃, short-term can withstand 100℃.
Compressive strength 0.3-0.6MPa, good toughness, not easy to break.
Support physical backblowing (0.6MPa compressed air) or chemical cleaning (acid/alkali soaking) regeneration.
Production Process of Sintered PE cap
Raw material processing
UHMWPE powder is selected and mixed with plasticizers, stabilizers and other auxiliary materials.
Mold filling and pre-pressing
The mixture is filled into the mold and pre-pressurized mechanically to form a preliminary shape.
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.
Post-treatment and processing
After demolding, cut to the required length and install the joints (e.g. M20, M30 thread).
Quality Inspection
Conduct bubble uniformity test, compressive strength test and chemical compatibility test.
Advantages of Sintered PE cap
High porosity (50%) and uniform pore size design, high flow rate and not easy to be clogged.
Can be repeatedly cleaned and regenerated, life expectancy of 1-3 years, the cost is lower than the ceramic cartridge.
Non-toxic and odorless, in line with the hygiene standards of the food and pharmaceutical industry.
Support customized shaped structure (piece, tube, rod, cap, etc.) and special precision requirements.
