Application of 4A Zeolite in Daily Chemical Industry

With environmental problems becoming more and more serious, people are paying more and more attention to the environmental aspects of daily life. Today, manufacturers of daily chemicals have begun to experiment with new methods of preparation, new additives to reduce the impact on the environment, and research on daily chemical products. In the case of alternatives to auxiliaries, it has been found that zeolites have this property, so which type of zeolite is specifically used?
What are the commonly used zeolites in the chemical industry? Zeolite is an aluminosilicate compound with a cubic lattice. According to different pore sizes and uses, there are 3A zeolite, 4A zeolite, 5A zeolite, 10X zeolite, 13X zeolite, 13XAPG zeolite, oxygen-enriched zeolite, XH series refrigerant, hollow glass and other types. Which is suitable for the chemical industry is 4A zeolite, 4A zeolite in the end what performance?

First, the surfactant is adsorbed, due to the pore structure of the zeolite 4A crystal, and the particles have a large specific surface area, so the adsorption performance of zeolite 4A is very strong. Adsorption of non-ionic surfactants, zeolite 4A is 3 times that of NTA (nitrilotriacetate) and sodium carbonate, and 5 times that of sodium tripolyphosphate (STPP) and sodium sulfate. This property is used in agglomeration molding. It is of great interest to produce more highly concentrated laundry detergents formulated with more surfactants to produce products with good washing and flow properties.

Second, with a certain degree of detergency, through the experiment on the same formula with different additives, change the additives compared detergency, found that 20% of the STPP, 20% of the zeolite, 4% of the polymer decontamination effect and 40% STPP is equivalent to adding 10% of sodium carbonate and 4.5% of polymer to 20% of the zeolite in the non-phosphorus formula, and the product with very good detergency is obtained. This has a great effect on the detergency of washing powder. .

Third, with anti-redeposition, 4A zeolite has a good oil adhesion, when sodium carbonate, CMC, sodium silicate and sodium sulfate and other additives added 4A zeolite, the nylon cloth significantly reduced the adsorption of oil pollution. When the particle size of 4A zeolite is 0.4-1.0 μm, the dispersibility is relatively good, and it can prevent adhesion on the fabric. Although the dispersibility of zeolite 4A is not as good as that of STPP, the problem of dispersion of the dirt can be solved by compounding with sodium polyacrylate, which has a certain effect on increasing the degreasing power of certain fabrics.

Four, 4A Zeolite and other additives have good compatibility, 4A Zeolite and other additives can properly complement their performance, 4A zeolite dispersibility of the dirt and the hardness of the ion chelation than STPP, but 4A zeolite and STPP Mixed use, detergency can achieve the effect of a single use of STPP. This is because STPP can rapidly complex calcium and magnesium ions from the solid surface and transfer it to 4A zeolite through the aqueous medium. 4A zeolites have poor ability to bind to magnesium ions and can be compensated by the combination of silicate and carbonate in the zeolite.

Fifth, safety is good, 4A zeolite is non-toxic and highly safe to the human body. No irritation to the eyes and skin, will not cause allergies, use safe and reliable. After being washed, it is deposited in the soil without causing pollution, and it can also improve the soil. 4A zeolite has no adverse effects on the ecology. This is of great significance in reducing the environmental pollution caused by daily chemicals such as washing powder.
