Alias: Sodium 2-propenoate homopolymer, S Sodium polyacrylate
CAS No.: 9003-04-7
Structural formula: I. Properties and Applications
PAAS is non-toxic, easily soluble in water, and can operate under alkaline and medium concentration conditions without scaling. PAAS can disperse microcrystals or sediments of salts such as calcium carbonate and calcium sulfate in water without precipitation, thereby achieving scale inhibition. PAAS is a commonly used dispersant. In addition to being used as a scale inhibitor and dispersant in circulating cooling water systems in power plants, chemical plants, fertilizer plants, refineries, and air conditioning systems, it is also widely used in industries such as papermaking, textile printing and dyeing, ceramics, coatings, and building materials. II. Technical Specifications Compliant with GB/T 2838-1997 Item | Specification | Appearance | Colorless or yellow liquid | Solid content % ≥ | 30.0 | 50.0 | Free monomer (calculated as AA) % ≤ | 0.5 | 1.0 | Density (20℃) g/cm3 ≥ | 1.15 | 1.20 | pH (original solution) | 6～8 | 6～8 |
Note: The company can customize sodium polyacrylate with different molecular weights and solid contents, such as 50%, according to customer requirements. III. Usage Method
PAAS is often used in combination with other water treatment agents. The specific formula and dosage of PAAS should be determined through testing based on the on-site water quality and equipment material conditions. When PAAS is used alone, the general concentration is 2～15 mg/L. When used in other industries, such as concrete water reducers or printing and dyeing, the dosage should be determined through testing. IV. Packaging and Storage
PAAS is packaged in plastic barrels, with each barrel containing 25 kg or 200 kg. Store in a cool indoor place. The shelf life is ten months. V. Safety and Protection
PAAS is neutral. During operation, pay attention to labor protection. Avoid contact with skin and eyes. In case of contact, rinse thoroughly with plenty of water. |
