Product Description

Polyacrylic Acid (PAA)

CAS No. 9003-01-4

Structural formula:

聚丙烯酸 PAA 结构式

1. Performance and use:

PAA is non-toxic, easily soluble in water, and can operate under alkaline and medium concentration conditions without scaling. PAA 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; PAA 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.

3. Usage

PAA is often used in combination with other water treatment agents. The specific formula and dosage of PAA are determined by tests based on the on-site water quality and equipment material conditions. When PAA is used alone, the general concentration is 1-15 mg/L. When PAA is used in other industries such as concrete water reducer and printing and dyeing, the dosage should be determined based on tests.

4. Packaging and storage

PAA is packed in plastic barrels, 25kg per barrel. Store in a cool place indoors, the storage period is 12 months.

5. Safety protection

PAA is weakly acidic. Pay attention to labor protection when operating it. Avoid contact with skin, eyes, etc. Rinse with plenty of water after contact.
