Polyacrylic acid (PAA) is a widely used polymer compound. The following are the main uses of polyacrylic acid:
Water treatment agent: Polyacrylic acid is often used as a water treatment agent for scale inhibition, corrosion inhibition, and dispersion of impurities in water. It can react with metal ions and hard scale to prevent their deposition and scaling, thereby maintaining the smooth and normal operation of pipelines and equipment.
Thickener: Due to the carboxyl groups on the molecular chain of polyacrylic acid forming hydrogen bonds with water molecules, polyacrylic acid has good thickening performance. Therefore, it is widely used as a thickener and can be used to prepare various liquid products, such as detergents, hand sanitizers, liquid cleaners, etc.
Dispersant: Polyacrylic acid has good dispersion performance, which can disperse pigments, pigment powders, mineral powders, etc. in solvents, improving their uniformity and stability. Therefore, polyacrylic acid is often used in the fields of painting, ink manufacturing, textile dyes, and pigment industries.
Sustained release agent: Polyacrylic acid can be used to prepare materials with sustained release properties by adjusting its molecular weight and crosslinking degree, such as drug release systems, coating materials, etc.
Personal care products: Polyacrylic acid can be used to manufacture personal care products, such as wipes, sanitary napkins, diapers, etc. It can absorb moisture and keep the material dry, while providing a soft and comfortable touch.
Cosmetics: Polyacrylic acid is used as an emulsifier, thickener, and moisturizer in cosmetics to adjust the viscosity and texture of products, increase consistency and ductility.
Please note that the specific methods and applications for using polyacrylic acid may vary depending on the manufacturing industry and product type. When using polyacrylic acid, please follow relevant regulations and follow safety operation guidelines.
