1. Molecular Sieve 3A
Molecular Sieve type 3A is an alkali metal alumino-silicate; it is the potassium form of the type A crystal structure. Type 3A has an aperture about 3 angstroms (0.3nm). It doesn't absorb any molecules larger than 3A. It’s used for absorbing water mainly. Yuanying Molecular Sieve 3A has quick absorption speed, high crushing resistance and pollution resistance, more regenerative times and long lifespan. It’s the best desiccants for the deep desiccation, refining and polymerization of the gaseous phase and liquid phase in the petrochemical industry. Typical Chemical Formula: 0.45 K2O. 0.55 Na2O. Al2O3. 2 SiO2. nH2O
