Chemical Properties White powder, odorless. Water-swellable, soluble in aqueous caustic soda.
Application 1. It can be used as a corrosion scale inhibitor, water stabilizer, paint thickener and water retention agent, flocculants, drilling mud treatment agent. 
2. The agent is used for the circulating cooling water treatment for equipment copper material with a excellent scale effect. At the amount of 100 mg/L, it can form chelate with the scale-forming ions in water of medium hardness and further flow with water, and can prevent the formation of iron oxide scale.
3. It can be used as a thickener and stabilizer in butter products, cream, tomato sauce. It can also be used as a dispersing agent in fruit juice, wine and spirits. It can improve the sense of taste of ice cream, and enhance its stability. It can also be used as surface freezing glue for freezing products and aquatic products, and can also play a role in preservation. It can also alter protein structure and enhance the viscoelasticity of food, and thus further improving the organization.
4. Thickener.
It has many functions in food as following: (1) Enhance the adhesion ability to raw flour protein. (2) Make starch particle to combine with each other and dispersion penetrate into the mesh structure of the protein. (3) Form dough with a dense texture and being smooth in its glossy surface. (4) It forms a stable dough colloid for preventing soluble starch exudation. (5) It has a strong water-holding capacity which can make moisture be uniformly maintained in dough and prevent drying. (6) It can be used to improve the dough extensibility. (7) Make the raw material in the oil component be stably dispersed into the dough. 2, it is used as the electrolyte for protein interactions, change the protein structure, and enhance food viscoelasticity and improve the organization. Application Example: (1) Bread, cakes, noodles, macaroni, improve utilization of raw materials, improve the taste and flavor with the amount of 0.05%. (2) Fish paste-like products, canned food, dried seaweed, etc., to strengthen its organization, to keep fresh flavor, enhanced sense of smell. (3) Sauce, tomato sauce, mayonnaise, jam, cream, soy sauce, thickeners and stabilizers. (4) Fruit juice, wine, etc., dispersants. (5) Ice cream, Kara honey Seoul sugar, improve taste and the stability. (6) Frozen food, aquatic products, surface jellies (preservation). 4, Owing to its slow dissolution rate in water; it can be pre-mixed with sugar, powdered starch syrup, emulsifier, etc., to improve the dissolution rate. 5, Sodium polyacrylate can be used as sugar, salt, beverage clarifying agent (polymer coagulant).
5. It can be used as a filtrate reducer in solid drilling industry.
6. This product is a good anion detergent and dispersants which can be combined with other water treatment agent compound used for oil field water, cooling water, boiler water treatment at high pH and at high concentration process without scaling.
Production methods 1. Add deionized water and 34 kg of isopropanol chain transfer agent to the kettle separately and heat it to 80 ~ 82 °C. Add drop wise 14 kg of ammonium per-sulfate aqueous solution and 170 kg of acrylic monomers. After completion of dropping, perform the reaction for 3 h; cool to 40 °C; add 30% aqueous NaOH solution to a pH value of 8.0 to 9.0 and then have water and isopropanol been distilled to get the final liquid products. Spray dry to give a solid product.
2. Acrylate or acrylic acid is reacted with sodium hydroxide to get sodium acrylate, remove the alcohol by-produced; concentrate; adjust the pH, and undergo polymerization reaction to get the final product with the catalysis of ammonium per-sulfate.
3. Acrylic acid and sodium hydroxide is reacted to get sodium acrylate monomer, and then polymerize into sodium polyacrylate with ammonium per-sulfate as the catalyst.
4. Add sodium polyacrylate (with molecule weight: 1000 ~ 3000) to the reaction vessel to obtain 30% aqueous solution.
Chemical Properties faintly grey crystalline solid
Usage Scale inhibitor, builder in detergents, aid in soap and detergent processing and control of water hardness.
