Properties：
PAAS is non-toxic, easily soluble in water, and can operate under alkaline conditions and medium concentration multiples without scaling.
Applications：
PAAS can disperse microcrystals or sediment of salts such as calcium carbonate and calcium sulfate in water to prevent them from precipitating, thereby achieving the purpose of scale inhibition. It is also a commonly used dispersant. In addition to being used as a scale inhibition dispersant in circulating cooling water systems of power plants, chemical plants, fertilizer plants, refineries, air conditioning systems, etc., it is also widely applied in industries such as papermaking, textile printing and dyeing, ceramics, coatings, and building materials.
