Product Overview
Description
Product Description
Molecular sieve 4A is a kind of alkali-metallic silicon-aluminum compounds, it is the sodium form of the type A crystal structure. Molecular sieve 4A has an effective pore opening of 4 angstroms (0.4nm). 4A molecular sieves can absorb the molecules which critical diameter is not more than 4 angstroms. 4A molecular sieve is used in the dryness of gases and liquid. If it lost effectiveness, 4A zeolite can be regenerated to reuse.
Product Application
1. Drying and removing trace impurities form natural gas.
2. Deeply drying gas and liquid.
3. Making and purifying gases.
4. Static drying for electronic component and easy perishable materials.
5. Drying for paints, coatings and fuels.
6. Separating and purifying for gas-liquid component.
