Applications:
PAA is innoxious and soluble in water; it can be used in situations of alkaline and high concentration without scale sediment. PAA can disperse the microcrystal of calcium carbonate, calcium phosphate and calcium sulfate. PAA is widely used as scale inhibitor and dispersant for circulating cool water system, papermaking, weave, dyeing, ceramic, painting, etc.
Usage:
PAA can be used as scale inhibitor and dispersant in circulating cool water systems of power plants, iron & steel factories, chemical fertilizer plants, refineries and air conditioning systems. The general dosage is 20~40% when PAA mixes organic phosphonate zinc salt. If it is added alone, the dosage is 5~20 mg/L according to water quality.
Packing and storage:
Normally In 25kg or 200kg net Plastic Drum, IBC's can also be used as required. Stored in cool and dry place in one year.
