Sodium Polyacrylate

- Nov 09, 2018 -

In synthetic detergents, it is common to use phosphates (such as tripolyphosphates) and aluminum salts (such as sodium aluminosilicate, 4A zeolite, kaolin, bentonite aluminum sulfate) as builders, and phosphates as builders. When the washing wastewater is discharged into lakes and rivers, it will produce “eutrophication”, which will cause algae and aquatic plants to reproduce abnormally and die quickly, resulting in water pollution and oxygen deficiency, which will threaten the growth of other aquatic organisms. It is said that due to the presence of phosphate in synthetic detergents, it will cause environmental pollution during its use. Therefore, after entering the 1970s, the United States, Canada, Switzerland, and Sweden stipulated that the use of phosphate in the production of synthetic detergents was restricted or prohibited. Later, other countries have made similar regulations. It is expected that in the late 1990s, all synthetic detergents in Europe will be phosphate-free, and scientific studies have shown that aluminum salts can cause chronic poisoning in plants, animals and humans (which can lead to biological death in severe cases), which is equally harmful to living things. Therefore, it is not enough to make the synthetic detergent only to be phosphatized, and it should be made without aluminizing. Only phosphate-free and aluminum-free synthetic detergents can be called non-toxic, non-polluting detergents.

The use of sodium polyacrylate as a builder is an ideal method for the manufacture of non-toxic, non-polluting detergents. Sodium polyacrylate is a new and efficient detergent builder that can replace the tripolyphosphate and other aluminum salts commonly used in detergents, thus eliminating the environmental impact of wastewater discharged from the use of sodium tripolyphosphate and aluminum salts. Pollution. The washing performance of sodium polyacrylate is far superior to that of traditional sodium tripolyphosphate. The washing effect is equivalent to 5 times the weight of sodium tripolyphosphate, that is, the dosage is only 1/5 of sodium tripolyphosphate, which can reduce the detergent. Cost, gaining significant economic benefits
