Polyacrylic Acid Sodium Salt Solid Use
Sodium polyacrylate dispersant is an important polymer compound with a wide range of uses:
I. Uses in the field of coatings and paints
Pigment dispersion
- Polyacrylic Acid Sodium Salt Solid can be adsorbed on the surface of pigment particles. Due to its molecular chain with a large number of carboxyl and other polar groups, these groups can prevent the pigment particles from agglomerating in the coating system through electrostatic repulsion and spatial site resistance effect. For example, in water-based coatings, the dispersion effect is very good for inorganic pigments such as titanium dioxide. When the pigment particles are evenly dispersed, the color of the paint is more uniform and the covering power can be effectively improved. - It also improves the fluidity of the pigment, which makes the paint easier to brush or spray during the construction process and reduces the probability of defects such as sagging and orange peel. 2.
Improve paint stability
- Sodium polyacrylate dispersant helps to maintain the stability of the coating system during the storage of the coating. It prevents pigment settling and ensures that no pigment delamination occurs when the paint is left for a long period of time. This is very important for prolonging the shelf life of the paint, especially for some industrial and architectural paints that need to be stored for a long time.
Second, the use in the ceramic industry
Dispersion of ceramic blanks and glazes
- In the preparation of ceramic blanks, it can disperse various mineral particles in ceramic raw materials, such as quartz, feldspar and so on. These mineral particles can be mixed more evenly under the action of the dispersant, which is conducive to the molding of the blank. In glaze, sodium polyacrylate dispersant can make the color and other additives in the glaze evenly dispersed, thus improving the quality of the glaze and making the glaze of ceramic products smoother and more uniform in color. 2.
Prevent agglomeration and precipitation
- Ceramic slurry in the preparation and storage process, the particles are easy to agglomerate and precipitate. Sodium polyacrylate dispersant effectively prevents the agglomeration and precipitation of ceramic particles through electrostatic repulsion and spatial resistance, ensuring the stability of ceramic slurry. This is particularly important for the production of some high-precision ceramic products, such as electronic ceramics, etc., because these products require high uniformity and stability of raw materials.
Third, the use of the paper industry
Fiber dispersion
- In the pulp preparation stage of papermaking, sodium polyacrylate dispersant can help disperse fibers. It can make paper fibers evenly distributed in water to avoid fiber flocculation. This can improve the evenness of the paper, so that the physical properties of the paper are more uniform, such as the strength of the paper, thickness and other more consistent distribution throughout the paper surface.
Filler dispersion
- Some fillers, such as calcium carbonate, talc, etc., are added in the papermaking process. Sodium polyacrylate dispersant can effectively disperse these fillers, improve the retention rate of fillers in the paper. After the filler is evenly dispersed in the paper, it can improve the optical properties of the paper, such as whiteness, opacity, etc., and at the same time, it can also reduce the production cost of paper, because the use of filler can reduce the amount of fiber to a certain extent.
Usage in detergents and cleaning agents
Preventing redeposition of dirt
- In detergents, sodium polyacrylate dispersant can prevent the dirt that has been washed down from being redeposited on the surface of the clothing or the object being cleaned. It disperses dirt particles in the detergent solution and keeps them in suspension through spatial potential resistance and electrostatic repulsion. For example, in the washing process of a washing machine, it can avoid the dirt from attaching to the clothes again during the washing process, so as to improve the washing effect. 2.
Auxiliary Cleaning Ingredient Dispersion
- There are various cleaning ingredients in detergents, such as surfactants and enzymes. Sodium polyacrylate dispersant can help these ingredients to be better dispersed in the washing liquid, so that they can give full play to their cleaning effect. Moreover, it can improve the fluidity and stability of the detergent and prevent the detergent from delamination or precipitation during storage.
V. Usage in printing and dyeing industry
Dye dispersion
- Sodium polyacrylate dispersant has good effect on dispersing dyes. It can make the dyestuff particles evenly dispersed in the dyeing solution to ensure uniform color in the dyeing process. In the process of high temperature dyeing and other processes, it can also prevent the agglomeration of dye particles, improve the dyeing rate, reduce the waste of dyes, and also improve the quality of dyed and printed fabrics, so that the color is more bright and uniform. 2.
Printing pulp dispersion
- In the printing process, the uniformity of printing pulp is crucial. Sodium polyacrylate dispersant can disperse the pigments, thickeners and other components in the printing pulp, so that the printing pulp has good fluidity and stability. This can ensure clear patterns and uniform colors in the printing process, and improve the quality and effect of printing.
