Insulating Glass Molecular Sieve
Insulating glass molecular sieve can simultaneously absorb moisture and residual organic substances inside insulating glass. It keeps the insulating glass smooth and transparent even under extremely low‑temperature conditions. It effectively relieves excessive internal‑external pressure difference caused by drastic temperature changes between seasons and day‑night cycles. Besides, it prevents twisting and cracking resulting from thermal expansion and contraction of insulating glass, and extends its service life.
Molecular Sieve 3A
Molecular sieve 3A is alkali‑metal aluminosilicate, the potassium‑type of A‑type crystal structure. Its effective pore size is about 3 Å (0.3 nm). It adsorbs molecules with effective diameter below 3 Å, while rejecting unsaturated hydrocarbons and other larger‑size molecules.
Main Applications
Drying of various liquids (e.g. ethanol)
Air drying
Refrigerant drying
Drying for natural gas and methane
Drying of unsaturated hydrocarbons, cracked gas, ethylene, acetylene, propylene, butadiene
Molecular Sieve 4A
Molecular sieve 4A is alkali‑metal aluminosilicate. It adsorbs molecules with critical diameter ≤4 Å, including water, NH₃, H₂S, SO₂, CO₂, C₂H₅OH, C₂H₆, C₂H₄. Widely applied for gas & liquid drying; it also purifies selected gas and liquid media, for example argon production.
Main Applications
Dehydration for electronic components, pharmaceuticals, food‑grade materials
CO removal & drying for natural gas, LPG, air, inert gas and atmospheric gas
Removal of hydrocarbons, ammonia and methanol from gas streams (ammonia syngas treatment)
Dehydration of refrigerant and air for air‑brake systems of buses, trucks and locomotives
