| sodium polyacrylate | sodium polyacrylate is a commonly used dispersant, also known as sodium 2-acrylate homopolymer, colorless or light yellow viscous liquid at room temperature, non-toxic, weak alkaline, insoluble in ethanol, acetone and other organic solvents, soluble in water and sodium hydroxide aqueous solution, but in calcium hydroxide, magnesium hydroxide and other aqueous solution with the increase in the number of alkaline earth metal ions, first dissolved and then precipitated. It can be operated under the conditions of alkali and medium concentration multiple without scaling, the molecular weight is about 500-3000, and the microcrystalline or sediment of calcium carbonate, calcium sulfate and other salts can be dispersed in water without precipitation, so as to achieve the purpose of scale inhibition, in addition to the use of power plants, chemical plants, fertilizer plants, oil refineries and air conditioning systems and other circulating cooling water systems in the scale and dispersant. Also widely used in paper and textile printing and dyeing, ceramics, coatings, building materials and other industries. |
