1 Used as scale inhibitor and dispersant in industrial water treatment. Compatibility is good. It can be used for pre-treatment of drinking water. It is used to separate red mud in the preparation of alumina.
2 It can be used as an excellent suspending agent, emulsifier, transparent matrix of advanced cosmetics and pharmaceutical excipient matrix, and is also the most effective water-soluble thickener. It is also used in toothpaste as a thickener and binder, and can be combined with other polymers Compatible use.
3 is a commonly used dispersant, which can disperse the crystallite or sediment of calcium carbonate, calcium sulfate and other salts in water without precipitation, so as to achieve the purpose of scale inhibition. In addition to being used as a scale inhibitor and dispersant in circulating cooling water systems, it is also widely used in papermaking, textile, printing and dyeing, ceramics, coatings and other industries.
4 Applied to water treatment of chemical industry, chemical fertilizer, printing and dyeing, power generation, etc.
