4A Molecular Sieve, Chemical Packing
4A Molecular Sieve
The 4A molecular sieve also called actived alumina zeolite 4A, is a kind of alkali metal aluminosilicate.
This sieve is widely used in drying, refining and purifying various gases and liquids. Because this kind of actived alumina zeolite 4A can absorb those objects whose molecule diameters are smaller than 4A molecular sieve, such as argon, krypton, xenon, ammonia, carbon monoxide, C2H5OH, C2H2, CH3OH, CH3CN2, CS2, CH3CL, CH3Br, C2H4 and so on.
Regarding the delivery period of this actived alumina zeolite 4A, 12days/20gp is for those to be exported abroad, and 7days/20gp is for the ones sold at home.
1.The 4A molecular sieve is applicable to the freezing agents of natural gases, various chemical gases, and liquids.
2.The actived alumina zeolite 4A is widely used as desiccant for various gases and liquids.
3.The 4A molecular sieve is suitable for purification and separation of gases, like methane, ethane and propane.
1.It should be preserved under room temperature.
2.Water, acid and alkali ought to be avoided.
3.Air isolation is quite necessary for this molecular sieve.
Featuring good wear, corrosion, high-temperature resistance, high strength and hardness, unique design and competitive prices, our 4A molecular sieve has been well received by customers from Southeast Asia, Middle East, Russia, United States, Canada, South America, Japan, Korea, Singapore, Thailand, Vietnam, Myanmar and so on.
