UOP 4A (球狀 & 條狀 & 粉狀)分子篩

Type 4A Molecular Sieve

Na12[(AlO2)12(SiO2)12] · X H2O--

Molecular Sieve Type 4A, the sodium form of the Type A crystal structure, is an alkali metal alumino-silicate. Available in powder, pellets,mesh and beads for static dehydration in a closed gas or liquid system. Used in packaging of drugs, electronic components, and perishable chemicals; and as a water scavenger in paint and plastic systems. Type 4A is also used commercially in drying saturated hydrocarbon streams.
