Polyacrylic Acid (PAA)
CAS: 9003-01-4
MF: C5H10O2
MW: 102.1317
Product Description
PAA is low toxicity, easily soluble in water, and can operate without fouling at alkaline and medium concentration ratios. It can form stable compounds with metal ions, calcium, magnesium, etc., and has excellent decomposition effect on calcium carbonate and calcium hydroxide in water. The molecular weight used for water treatment is generally 2000-5000. PAA can disperse the microcrystals or sediment of salts such as calcium carbonate and calcium sulfate in water without precipitation, so as to achieve the purpose of scale inhibition. PAA is a commonly used dispersant, in addition to being used as a scale inhibitor and dispersant in circulating cooling water systems such as power plants, chemical plants, fertilizer plants, oil refineries and air conditioning systems, it is also widely used in paper and textile, printing and dyeing, ceramics, coatings, building materials and other industries.
