Why use 3A molecular sieve for insulating glass desiccant?

Molecular sieve is a kind of crystalline aluminosilicate with uniform pore size and extremely high specific surface area. According to the crystal phase structure, it can be divided into 3A molecular sieve, 4A molecular sieve, 5A molecular sieve, 13A molecular sieve, etc. It absorbs moisture strongly and effectively, and can adsorb methanol. , Ethanol, hydrogen sulfide, carbon dioxide, etc. Product features: non-toxic, harmless, non-corrosive; stable chemical properties, abrasion resistance, and strong mechanical strength; moisture absorption performance is less affected by environmental humidity, and can still be large in ultra-low humidity (RH=5% or less) Absorb moisture, and have strong moisture control ability; it can be regenerated and reused for many times; product applications: widely used in the dehydration of various liquids, paints, fuels, and coatings, and the drying and drying of liquefied petroleum gas and liquid hydrocarbons. Desulfurization, drying of air, natural gas, acetylene, propylene, acetylene, etc.; also used for moisture-proofing of high-end products such as biopharmaceuticals and semiconductors.
