CAS No. 9003-04-7
Structural Formula:
Properties:
PAAS is innoxious and soluble
in water, it can be used in situations of alkaline and high
concentration without scale sediment.
PAAS can disperse the microcrystals or
microsand of calcium carbonate, calcium phosphate and
calcium sulfate.
PAAS is used as
scale inhibition and dispersant for circulating cool
water system, papermaking, weave, dyeing, ceramic, painting,
etc.

Usage:
PAAS can be used as scale inhibitor
and dispersant in circulating cool water systems in power
plants, iron & steel factories, chemical fertilizer plants,
refineries and air conditioning systems. Dosage should be in
accordance with water quality and equipment materials. When
used alone, 2-15mg/L is preferred. When used as dispersant,
the dosage should be determined by experiment.
