zeolite adsorbent Adsorption of nonionic surfactants

4A molecular sieves are three times NTA (nitrilo triacetate) and sodium carbonate, sodium tripolyphosphate is 5 times (STPP) and sodium sulfate, and the nature of the agglomerates formed in production of highly concentrated detergent formulated with more surfactant to prepare a good washing and flow properties of the product makes sense. Through the experiment, the liquid carrying capacity of zeolite 4A ≥ 30%, was added 4A  molecular sieves in the detergent production process, to increase the flowability zeolite adsorbent of the material, to adjust the viscosity, the appearance of the product obtained, sexual fluidity and good anti-caking product.
Detergency: experimental formulations containing the same type of additives, additives to change the detergency compared and found 20% of the STPP, 20% of zeolite, 4% polymer and 40% of the decontamination effect is quite STPP in 20% of the non-phosphorus zeolite was added 10% sodium carbonate and 4.5% of the polymer obtained very good detergency products.
Anti-redeposition properties: 4A zeolite has good adhesion of oil, when the sodium carbonate, CMC, sodium silicate and sodium and other additives added zeolite adsorption nylon cloth zeolite adsorbent significantly reduce oil pollution. When the particle size of the zeolite 0.4-1.0μm, better dispersibility can be prevented from adhering on the fabric.
Although not as good as 4A zeolite dispersing ability STPP, but with the sodium polyacrylate dispersion can solve complex problems of dirt.
Compatibility with other additives: 4A Zeolite and other additives can properly complement its performance, 4A zeolite dispersion of dirt on the hardness ions and chelating better than STPP, but 4A Zeolite and STPP mix, detergency can STPP achieved with a single effect. This is because the energy from the solid surface STPP rapid complexation of calcium and magnesium ions to pass through the water medium 4A molecular sieves. 4A Zeolite magnesium ion binding ability, through the zeolite complex silicates, carbonates compensation.
