4A molecular sieve

4A molecular sieve is an alkali metal aluminosilicate , can adsorb water , NH3, H2S, sulfur dioxide, carbon dioxide , C2H5OH, C2H6, C2H4 and other critical molecular diameter less than 4A . Widely used in gas and liquid drying , can also be used in certain gas or liquid purification and purification , such as argon gas from the system.

Molecular sieve is a kind of synthetic with micro groove cubic lattice sialic acid salts. According to the internal cavity of the crystal size and adsorption or reject molecules of different material, thus is called "molecular sieve". Molecular diameter less than the material can enter the molecular sieve of molecular sieve pores diameter crystal crystal, thus by adsorption, otherwise, the rejection. Molecular sieves are determined according to the different material molecular polarity of priority in the order of the adsorption.

According to the molecular adsorption effect on the choice of the size and shape of the different, namely only those smaller than the molecular sieve adsorption aperture molecules. For small polar molecules and unsaturated molecules, has selective adsorption performance, the larger the polarity, not the higher the degree of saturation, the choice and the stronger adsorption. Type A molecular sieve is A kind of molecular sieves which, its structure and NaCl are similar, belong to the cubic crystal system. Due to the 4 a molecular sieve effective aperture of 0.4 nm, so called 4 a molecular sieve, the space network structure by the silicon oxygen tetrahedron element [SiO4] and alumina tetrahedron unit [AlO4] staggered.

Application

1. Polyester additives agent: the role of 4 a zeolite as detergent additives mainly calcium ion exchange the water softening water, remove dirt and prevent dirt deposition. 4 a molecular sieve is most used in the generation of phosphorus to help lotion and apply the most sophisticated products. 4 a molecular sieve to replace sodium tripolyphosphate as detergent builder to solve the pollution of the environment has a major role. 4 a molecular sieves also can be used as a soap abrasive molding agent, toothpaste, etc.

2. Environmental protection, sewage treatment, 4 a molecular sieves can remove the NH3 - N in the sewage and Pb2 +, Cu2 +, Zn2 +, and Cd2 +, etc. Industry and agriculture, civil, and aquatic animal husbandry in the discharge of wastewater containing ammonia nitrogen, not only harm fish such as survival, pollution in aquaculture environment, and promote the growth of algae, and lead to the blocking of rivers and lakes. Due to the 4 a molecular sieve of NH4 + high commutativity choice, has been successfully applied in the field. From metal mining, smelting, metal surface treatment and effluent from chemical industry and other departments, containing heavy metal ion great harm to human body. Deal with the sewage with 4 a molecular sieves in addition to guarantee water quality qualified, can also recycle heavy metal.

3. The other purposes:

(1) water treatment - hard water softener, can replace the current widespread use of sulfonated coal in our country, thus reducing costs;

(2) the metallurgical industry - separating agent, separation, extraction from brine potassium, rubidium, cesium, etc. In industry for enrichment, separation and extraction process;

(3) the petrochemical industry, catalyst, desiccant, adsorbent;

(4) agriculture - soil conditioner;

(5) the medicine - silver zeolite antimicrobial agent.
