Molecular Sieves are industrial materials that utilize a uniform microporous structure to adsorb moisture and impurities, making them suitable for natural gas purification, refrigeration system drying, and chemical separation processes.
Highly Selective Adsorption
Molecular Sieve uses 3A–13X pore structures to selectively adsorb water, CO₂, and impurities, improving purification efficiency.
High Mechanical Strength
Made from high-silica zeolite crystals and high-temperature calcination, it forms a stable structure with 20–80 N compressive strength and low breakage.
Low Attrition Rate
Controlled molding and secondary screening ensure uniform particles with attrition below 0.3%, reducing blockage and contamination risks.
Extended Service Life
Under normal operating conditions, Molecular Sieve maintains stable performance for 2–5 years in continuous gas drying systems.
Compatible Equipment Systems
Widely used in PSA oxygen generators, compressed air dryers, natural gas purification, and refrigeration adsorption systems.
Quality Control
Raw Material Inspection
Zeolite raw materials are tested for silica-alumina ratio, purity, and impurity elements to ensure stable synthesis quality.
Crystallization Process Control
During hydrothermal synthesis, temperature, pressure, and reaction time are strictly controlled to ensure uniform crystal structure formation.
Ion Exchange Control
For 4A/5A/13X types, sodium, calcium, or other ion exchange levels are tested to ensure correct adsorption selectivity.
Washing and Filtration Check
Conductivity and pH of filter liquid are monitored to ensure removal of residual alkali and impurities.
Drying Process Monitoring
Drying temperature and time are controlled to maintain pore structure integrity and prevent collapse.
Activation and Calcination Control
High-temperature activation is controlled to stabilize crystal structure and ensure strong adsorption performance.
Particle Size Screening
Sieve analysis ensures uniform bead or pellet size distribution according to industrial application requirements.
Crushing Strength Test
Mechanical strength is tested to ensure particles can withstand pressure in adsorption towers and transport.
Water Adsorption Capacity Test
Standard humidity adsorption testing is performed to verify moisture removal efficiency.
Bulk Density Test
Density is measured to ensure stable filling performance and consistent bed packing behavior.
Thermal Stability Test
High-temperature resistance is evaluated to ensure performance stability under working conditions.
Final Batch Inspection
All key indicators are rechecked before packaging to ensure consistency and export compliance.
