5A Molecular Sieve Powder
〖Product Usage〗
The original 5A molecular sieve powder refers to calcium A-type aluminosilicate. The original 5A molecular sieve powder can adsorb molecules with a critical diameter not greater than 5 ?. Mainly used for molecular sieve forming and molecular sieve activation powder production.
〖Features〗
The raw powder is produced by Chengdu Shengli Technology Co., Ltd. using the new technology of synchronous cycle exchange. It has:
· High CO? adsorption capacity;
· High degree of exchange, good thermal stability, low sieve residue
〖Chemical Equation〗
-CaO·-Na?O·Al?O?·2.0SiO?·4.5H?O
