4A Zeolite: Usage: zeolite is the frame-shaped aluminum silicate of alkali metals and alkaline earth metal which contains water. Because of its ion exchange and adsorption, it is widely used in agriculture, petrochemical industry, environment protection, extracting potassium from seawater, water treatment, macromolecule chemical industry, concrete, food, paper making, electronics and manufacture of building materials industry etc. As a high efficiency desiccant, it can separate, purify and refine various gas and liquid in chemical and petroleum industries, and also can be taken as a kind of activator and catalysis carrier to adsorb nitrogen in the air alternatively. Molecular sieve containing much oxygen can be used as ion exchanger for seawater desalination, extracting rare element, compounding detergent etc. It can be used as a storage unit for fission products and radioactive isotope in atomic energy industry; it can also be used as the adsorption carrier for defoliant, ripening agent, insecticide, etc.
