Sodium polyacrylate (PAAS) is a polymer compound commonly used as an anionic dispersant and thickener. It has multiple functions and effects in many fields, among which the following are the main ones:
Dispersion effect: Sodium polyacrylate has good dispersion performance, which can stably disperse solid particles in the liquid and prevent their aggregation and precipitation. This is very important for the dispersion of suspended solid particles in industries such as dyes, pigments, and coatings, which can maintain the uniformity and stability of the product.
Thickening effect: Sodium polyacrylate has high viscosity in water, which can increase the viscosity and rheological properties of the liquid. In some processes, such as printing, dyeing, coating, etc., it can act as a thickener to improve the fluidity and coating properties of liquids.
Antibacterial effect: Sodium polyacrylate has certain antibacterial properties, which can inhibit the growth and reproduction of some bacteria and microorganisms. Therefore, it is often used as a preservative and antibacterial agent in certain disinfection and cleaning products, skincare products, detergents, etc.
Water treatment function: Sodium polyacrylate plays an important role in water treatment, which can react with metal ions in water to form stable complexes and reduce the adverse effects of metal ions on water quality and equipment. It can be widely used in fields such as boiler water treatment, circulating cooling water treatment, sewage treatment, etc.
It is recommended to refer to relevant technical materials, follow usage guidelines, and safety operation specifications when selecting the correct type and concentration of sodium polyacrylate based on specific application scenarios and needs.
