Polyurethane Dehydration
  Polyurethane DehydrationActivated zeolite powders/ Molecular Sieve Powdersare widely used in 1K- or 2K- polyurethane systems to prevent the formation of foam and bubbles by suppressing the reaction of free water with isocyanate group. Lean more> One of problems Polyurethane adhesives is the moisture.If not removed, moisture will react with the isocyanateconstituent to form gaseous carbon: RNCO + H2O → RNH2 + CO2>Activated zeolite...
   
   
Ethanol Dehydration
  Ethanol dehydrationEthanol as manufactured is rectified spirit, which is 94.68% alcohol, and rest is water. It is not possible to remove remaining water from rectified spirit by straight distillation as ethanol forms a constant boiling mixture with water at this concentration and is known as azeotrope.Moleculare Sieve 3A is widely used for ethanol dehydration process in large industrial absolute ethanol plan. Lean more  ...
   
   
Nature Gas Dehydration
  Nature Gas DehydrationAs raw nature gas normally contains saturated water, hydrogen sulfide, carbon dioxide and other impurities. These impurities should be removed by Molecular Sieve as much as possible in order to meet the requirement of marketable gas.Molecular Sive 4A and 5A are widely used by in nature gas dehydration process. Learn more>After dehydration by molecular sieve the dew point of natural gas decrease signifi...
   
   
Refrigerant Dehydration
  Refrigerant dehydrationIn the air-conditioning refrigeration system, molecular sieves can effectively remove moisture and other contaminants from refrigerant, thus avoiding ice formation and protecting the system from blockage and corrosion. Lean more >Refrigerant is mainly a chloride or fluoride containing hydrocarbon in refrigerating plants.>During refrigerant diffusion process, some residual moisture out of...
   
   
Air Brake System
  Air brake systemMolecular sieve 4A is widely used in air brake system of buses, trucks, trains and ships to keep air as dry as possible and avoid any freezing in the circuit but also any corrosion of the metallic parts. Lean more >The moisture in gas brake system may corrode the pipe and affect the braking effect. What is more serious is that the braking system is no longer in force.>Molecular sieve 4A is an effecti...
   
   
Cryogenic ASU
  Cryogenic ASUFor cyogenic air separation unit(ASU), oxygen, nitrogen, and argon was separated in low temperature according to the difference on boiling point of them. So the moistureand CO2in the air must be removed in order to avoid them freezing in pipeline. Molecualr sieve 13X and JLOX-300 are competent product to remove moisture and CO2 and othersmaller hydrocarbon moleculesfrom air. ...
   
   
PSA Oxygen Generator
  PSA oxygen generatorPSA oxygen generators work in presure swing adsorption process by taking the advantage of molecualr sieve, which can adsorb nitrogen in the air at higher pressure and desorb it atatmospheric pressure.Molecular sieve JLOX-500 is specially designed and developed for PSA oxygen generator, which has stable and efficient performance. Lean more >PSA process is widely used for producing riched oxygen from molecu...
   
   
VPSA Oxygen Generator
  VPSA oxygen generatorVacuum pressure swing adsorption(VPSA)is non cryogenic air separation technology, preferable for small and medium sized oxygen generators, which adopts molecular sieve as adsorbent.Molecular sieve JLOX-100 series is specially developed Lithium type molecular sieve for VPSA oxygenerators. Lean more > Molecular sieve JLOX-100 seri...
   
   
Medical Oxygen Generator
  Medical Oxygen GeneratorMedical oxygen generator is widely accepted in the market, which works under PSA or VPSA process by using special developed molecular sieve JLOX-501. Lean more> Molecular sieve JLOX-501 is sodium type molecular sieve and molecular sieve JLOX-101 is lithium type molecular sieve which have very fine particle size in order to get faster adsorption and desorption capacity.> The performance of this two kind of molecular si...
