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.

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 microcrystals or microsand of calcium carbonate, calcium phosphate and calcium sulfate. PAA is used as scale inhibitor and dispersant for circulating cool water system, papermaking, weave, dyeing, ceramic, painting, etc.

GTETH-610 is composed of organophosphines acid, polycarboxylic acid and sulfosalt copolymers. It has properties of chelation and dispersion, has good synergistic effect and can bring about crystal distortion. The particles are dispersed in water system and are removed later, through which the dusty water system can be operated normally.

TH-607 is built with organophosphoric acid, special surfactant and synergistic agents, It can chelate with Ca2+ and Mg2+. TH-607 can effectively chelate and disperse calcium carbonate, calcium sulfate and calcium phosphate scales. TH-607 is used as scale inhibitor for pipeline of oilfield refill water.
