High quality 4A molecular sieve
Basic Info
Model No.: 4A
Product Description
4A molecular sieve is sodium exchange, with a pore size of 4A (about 0.38nm), which can be called sodium molecular sieve; it can adsorb water, methanol, ethanol, hydrogen sulfide, sulfur dioxide, carbon dioxide, and does not adsorb any molecules with a diameter greater than 4A. Whoever chooses it The performance is higher than any other molecule, and it is one of the most used molecular sieve varieties in the industry Application: Remove moisture from materials

Application:
Detergent additives
The role of 4A molecular sieve as a detergent additive is mainly to exchange calcium ions in water to produce softened water, remove dirt and prevent dirt re-deposition. 4A molecular sieve is currently the most widely used and most mature product among the phosphorus-replacement builders. The replacement of sodium tripolyphosphate with 4A molecular sieve as a detergent aid plays a significant role in solving environmental pollution. 4A molecular sieve can also be used as a forming agent for soap and a friction agent for toothpaste.
Sewage treatment
4A molecular sieve can remove NH3-N and Pb2+, Cu2+, Zn2+, and Cd2+ in sewage. The sewage discharged from industrial, agricultural, civil and aquatic animal husbandry contains ammonia nitrogen, which not only harms the survival of fish and other fish, pollutes the internal breeding environment, but also promotes the growth of algae and causes the blockage of rivers and lakes. Due to the high selective exchange of 4A molecular sieve for NH4+, it has been successfully applied in this field. Sewage from metal mines, smelters, metal surface treatment and chemical industry, etc., contains heavy metal ions that are extremely harmful to humans. Using 4A molecular sieve to treat these sewage can not only ensure the water quality is qualified, but also recover heavy metals.
Other uses
(1) Water treatment-hard water softener, which can replace the sulfonated coal widely used in our country, thereby reducing costs;
(2) Metallurgical industry-separating agent, separating and extracting potassium, rubidium, cesium, etc. in brine. Used in industrial processes such as enrichment, separation and extraction of metals;
(3) Petrochemical industry-Catalyst, desiccant, adsorbent;
(4) Agriculture-soil amendment;
(5) Medicine-silver zeolite antibacterial agent.
