Use : It is mainly used for deep drying of air, natural gas, alkane, refrigerant gas and liquid.
Static drying for argon preparation and purification, drug packaging, electronic components and volatile materials , as a dehydrating agent for oil paint, paint, fuel.
Description : 4A molecular sieve pore size is 4A, can absorb water, methanol, ethanol, hydrogen sulfide, sulfur dioxide, carbon dioxide, ethylene, propylene, can't absorb molecular sieve that diameter greater than 4A(including propane), the water selecting adsorption performance is higher than other molecules. 4A is the largest one of the molecular sieve varieties of industrial usage.
