Application of molecular sieves 4A

Detergent additives: 4A zeolite as a detergent additive main function is to produce calcium ion exchange water softening, remove dirt and prevent redeposition. zeolite 4a is currently applied on behalf of the largest builders of phosphorus and most mature product. 4A Zeolite replace sodium tripolyphosphate as detergent additives to solve the environmental pollution has a major role. 4A Zeolite forming agent can also be used soap, toothpaste friction agent.
Sewage: molecular sieves 4a can remove sewage NH3-N, and Pb2 +, Cu2 +, Zn2 + ,, Cd2 + and so on. Industry, agriculture, animal husbandry and aquatic civilian discharged wastewater containing ammonia nitrogen, not only endanger the survival of fish, in the farming environment pollution, and promote algae growth, leading to blockage of rivers and lakes. molecular sieves 4a due to high selectivity of NH4 + exchangeable, has been successfully applied in the field. Sewage from metal mines, smelters, metal surface treatment and chemical emissions from industry and other sectors, which contains heavy metal ions harmful to human health. 4A molecular sieves with sewage in addition to those qualified to ensure the water quality, but also the recovery of heavy metals.
Other uses:
(1) Water ---- hard water softener, can replace the current widespread use of sulfonated coal, thereby reducing costs;
(2) Metallurgical Industry ---- separating agent, separation, extraction of brine potassium, rubidium, and cesium. In industry for the enrichment, separation and extraction of metals and other processes;
(3) petrochemical industry ---- catalysts, desiccants, adsorbents;
(4) ---- agricultural soil conditioner;
(5) Pharmaceutical ---- silver zeolite antimicrobial agent.
