(Scope of application reference ‘product usage’)
Due to the pore structure of the 4A zeolite crystal and the large ratio of the particles to the surface, the 4A zeolite has strong adsorption properties. In terms of adsorption properties of non-ionic surfactants, 4A zeolite is 3 times of subamino triacetate (NTA) and sodium carbonate, and 5 times of sodium tripolyphosphate (STPP) and sodium sulfate, this property is generally used in the production of highly concentrated laundry detergent, which can be combined with more surfactants, thus greatly improving the washing performance and fluidity of washing products.

Product Usage
Daily chemical industry
(1) Used as a washing aid. The role of 4A zeolite as a detergent additive is mainly to exchange calcium and magnesium ions in the water, so that the water can be softened and prevent the redeposition of dirt. At present, 4A zeolite is the most widely used and most mature product in replacing phosphorus-containing additives. The substitution of 4A zeolite for sodium tripolyphosphate as washing assistant is of great significance to solve environmental pollution.
(2) 4A zeolite can also be used as a molding agent for soap.
(3) 4A zeolite can also be used as a friction agent for toothpaste. At present, the amount of 4A zeolite in washing products is the largest. As 4A zeolite for washing, it is mainly required to have a higher calcium exchange capacity and a faster exchange rate.
Environmental protection industry
(1) For sewage treatment. 4 human zeolite can remove Cu2 Zn2+Cd2+ in sewage. The sewage from industry, agriculture, civil and aquatic animal husbandry contains ammonia nitrogen, which not only endangers the survival of fish, pollutes the internal culture environment, but also promotes the growth of algae, leading to the blockage of rivers and lakes. 4A zeolite has been successfully applied in this field because of its high selectivity for NH. It comes from the sewage discharged by metal mines, smelters, metal surface treatment and chemical industry, which contains heavy metal ions which are very harmful to human body. Treating these sewage with 4A zeolite can not only ensure the quality of water, but also recover heavy metals. As a 4A zeolite for sewage treatment, due to the removal of harmful ions in sewage as much as possible, products with relatively high crystallinity are needed.
(2) Improve drinking water quality. Using the ion exchange properties and adsorption properties of zeolite, the circulation system is used to detoxify seawater and soften hard water, and selectively remove or reduce the harmful elements/bacteria/viruses in some drinking water sources.
(3) Harmful gas treatment. Applications in this area include industrial gas purification, industrial and domestic waste gas environmental treatment.
Plastic processing
In the plastic processing industry, especially polyvinyl chloride (referred to as PVC), calcium/zinc heat stabilizer is used to absorb free hydrogen chloride during PVC processing to prevent PVC degradation (that is, aging). 4 A zeolite is not only alkaline, but also has a porous internal structure, so it can neutralize and adsorb the free hydrogen chloride in VC, which can prevent the aging of PVC. When 4A zeolite is used with calcium/zinc heat stabilizer, 4A zeolite not only plays the role of heat stabilizer, but also reduces the wood formation of calcium/zinc heat stabilizer. 4 A zeolite is used as a PVC heat stabilization agent, which is environmentally friendly and economical. At present, the application of 4A zeolite on PVC is in its infancy, and it is expected that there will be a huge demand in the near future. China is A big country in PVC production and processing, the output of PVC is the first in the world, and there is still an annual increase of 5-8% in the future, therefore, the application of 4 A zeolite in PVC has broad prospects. As A PVC heat stabilization agent with 4 A zeolite, there are more strict restrictions on its foreign substances such as black spots, generally no more than 10 /25go because the black spots are generally hydrophilic, and PVC and other polymer organic compounds (hydrophobic) incompatible, resulting in defects in processed products, affecting the strength and appearance of products.
Agricultural fertilizer
(1) Used as a soil amendment. The cation exchange property and adsorbability of zeolite can be used as soil amendment directly to improve the supply of beneficial trace elements needed by crops, reduce the acidity of soil and increase the base exchange capacity of soil.
(2) Used as long-acting fertilizer and fertilizer slow-release agent. For example, the combination of zeolite with dihydroamine, hydrogen cheese, rare earth elements and other trace elements can prepare a long-term fertilizer synergist, which can not only greatly extend the fertilizer effect period of nitrogen fertilizer, and improve the utilization rate of nitrogen fertilizer, but also significantly improve the nutritional status of crops, promote the growth and development of crops, improve the antiviral ability, and increase crop yield.
(3) Used as a feed additive. Using the adsorption and cation exchange properties of zeolite as a carrier to produce feed additives, it can enhance the antiviral ability of feeding animals, promote protein synthesis, accelerate weight gain effect and improve feed utilization rate.
(4) Used as a preservative. The adsorption and exchange properties of zeolite can be used to prevent and control crop diseases and pests, and improve the preservation and preservative ability of agricultural products such as vegetables and fruits and aquatic products.
Metallurgical industry
In the metallurgical industry, it is mainly used as a separation agent to separate and extract potassium, shuai, flower in brine and for enrichment, separation and extraction of metals and other processes; It can also be used for the refining and purification of certain gases or liquids, such as the preparation of nitrogen, the separation of methane, ethane, and propane.
Paper industry
The application of zeolite as filler in the paper industry can improve the performance and quality of paper, so that its porosity increases, water absorption is enhanced, it is easier to cut, writing performance is improved, and it has certain fire resistance.
Coating industry
As the filling agent and quality pigment of coating, zeolite can give the coating resistance, wear resistance, corrosion resistance, heat resistance and climate change resistance.
Petrochemical industry
4A molecular sieve is mainly used as adsorbent, desiccant and catalyst in the petrochemical industry.
(1) as an adsorbent. 4A molecular sieve is mainly used for the adsorption of substances with molecular diameter less than 4A, such as water, methanol, ethanol, hydrogen sulfide, sulfur dioxide, carbon dioxide, ethylene, propylene, and the adsorption performance of water is higher than that of any other molecule.
(2) as a desiccant. 4A molecular sieve is mainly used for the drying of natural gas and various chemical gases and liquids, refrigerants, pharmaceuticals, electronic materials and volatile substances.
(3) as a catalyst. 4A molecular sieve is rarely used as catalyst. In the field of catalysis, X zeolite, Y zeolite and ZK-5 zeolite are mainly used. The petrochemical industry basically needs 4A molecular sieve type zeolite, therefore, it requires a high degree of crystallinity.
