Polymer Dispersant

Polymer dispersant is a commonly used scale dispersing agent, able to calcium carbonate, calcium sulfate salts of microcrystalline or sediment in the water does not spread precipitation, which aims to achieve broad scale used as paper coatings Architectural Coatings and the dispersing agent, concrete retarder, as well as water-reducing admixture for textile printing and dyeing industries chelating dispersant.

 (1) Polyacrylic Acid (PAA) is Polymer dispersant, 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. Polymer dispersant PAA is used as scale inhibitor and dispersant for circulating cool water system, papermaking, weave, dyeing, ceramic, painting, etc.

(2) Hydrolyzed Polymaleic Anhydride (HPMA) is a low molecular weight polymeride, with average molecular weight 400-800. No toxicity, soluble in water, high chemical and thermal stability, decomposed temperature above 330℃. Polymer dispersant HPMA has obvious threshold effect under high temperature (350℃) and high pH(8.3)level, suitable to be used in alkaline water system or built with agents. Polymer dispersant HPMA has good scale inhibition against carbonate and phosphate scales under temperature 300℃ with effective time as long as 100 hours.

(3) Copolymer of Maleic and Acylic Acid (MA/AA) is a low molecular weight polyelectrolyte, a copolymer of maleic anhydride and acrylic acid. It has good dispersant performance against carbonate and scale inhibition for phosphate. it has good thermal stability, can be used under high temperature (300℃). MA/AA has good compatibility when used together with other agents.

(4) Acrylic Acid-2-Acrylamido-2-Methylpropane Sulfonic Acid Copolymer (AA/AMPS) is the copolymer of acrylic acid and 2-acrylanmido-2-methylpropanesulfonic acid (AMPS). Due to including carboxylic group (scale inhibition and dispersion) and sulfonic acid group (strong polarity) in this copolymer, AA/AMPS has high calcium tolerance and good scale inhibition for calcium phosphate, calcium carbonate and zinc scale.

(5) Acrylic Acid-2-Hydroxypropyl Acrylate Copolymer (T-225) is copolymer of polyacrylic acid and hydroxypropyl acrylate, it has good scale inhibition and dispersion properties to calcium phosphate and calcium carbonate, it has good dispersion properties to ferric oxide sludge, clay and grease.

 (6) Acrylic Acid/Acrylate/Phosphonic Acid/Sulfosalt Tetra-copolymer (TH-241) is copolymer of carboxylic group, hydroxylic group and sulfonic acid group, it has good scale inhibition performance to calcium phosphate and calcium carbonate. TH-241 has good synergic effects with other agents. TH-241is used as scale inhibitor and dispersant in circulating cool water system and built with organophosphate.

(7) TH-613 Acrylic-acrylate-sulfosalt copolymers is a scale inhibitor and dispersant containing sulfosate and polyelectrolyte. In this copolymer, there exists strong acid, weak acid and non-ion group, it is suitable to be used in high temperature, high pH, high hardness and high alkaline. TH-613 has good scale inhibition for ferric oxide, calcium phosphate, zinc phosphate and calcium carbonate.

(8) Copolymer of Phosphono and carboxylic Acid (PCA) has good dispersion property for scale of calcium carbonate and calcium phosphate in circulating cool water system. It has good scale inhibition for barium sulfate, strontium sulfate and silica scale. PCA has advantages in wide range of water quality, chemical stability, strong chlorine tolerance, etc.

(9) TH-3100 Carboxylate-Sulfonate-Nonion Tri-polymer is a good scale inhibitor and dispersant for cool water treatment, it has good inhibition for dry or hydrated ferric oxide. TH-3100 is a all organic dispersant and scale inhibitor, it can be also used as stabilizer of corrosion inhibitor for phosphate and phosphinic salt.

(10) Sodium of Polyaspartic Acid (PASP) is a water soluble polymer. It is a green water treatment agent, with properties of non-phosphor, non-nitrogen, non-pollution and fully biodegradation. PASP has good scale inhibition on calcium carbonate, calcium sulfate, barium sulfate, calcium phosphate, etc.
