Polyacrylic Acid Sodium (PAAS)
CAS No. 9003-04-7
Alias:2-Sodium acrylate homopolymer, S-sodium polyacrylate
Structural formula:
PAAS is non-toxic, easily soluble in water, and can operate under alkaline and medium concentration conditions without scaling. PAAS can disperse microcrystals or sediment of salts such as calcium carbonate and calcium sulfate in water without precipitation, thereby achieving the purpose of scale inhibition; PAAS is a commonly used dispersant. In addition to being used as a scale inhibitor dispersant in circulating cooling water systems such as power plants, chemical plants, fertilizer plants, refineries and air conditioning systems, it is also widely used in papermaking and textile printing and dyeing, ceramics, coatings, building materials and other industries.

| Limiting viscosity(30℃)/dl·g-1 | 0.06～0.10 | -- | -- | -- | -- |
PAAS is often used in combination with other water treatment agents. The specific formula and dosage of PAAS are determined by tests 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 PAAS is used in other industries such as concrete water reducer and printing and dyeing, the dosage should be determined based on tests.
PAAS is packed in plastic barrels, 25kg or 200kg per barrel. Stored in a cool place indoors, the storage period is ten months.
PAAS is neutral. Pay attention to labor protection during operation and avoid contact with skin, eyes, etc. Rinse with plenty of water after contact.
