Usage of PBTCA
1.Water Treatment High-Temp Scale & Corrosion Inhibitor
Low-phosphorus phosphonocarboxylate chelator with dual phosphonic & carboxylic functional groups for industrial circulating cooling water.
Superior scale inhibitor for calcium carbonate, sulfate and phosphate scales under high temperature, high hardness and high alkalinity working conditions.
Stable zinc salt stabilizer & mild steel corrosion inhibitor, excellent chlorine oxidation resistance for high concentration multiple water systems.
2.Compound Water Treatment Formulation Auxiliary
Premium synergistic monomer matched with zinc salts, polycarboxylate copolymers for compound scale-corrosion inhibitor formulas.
High-efficiency metal ion dispersant for oilfield injection water, power plant boiler water and reverse osmosis membrane pre-treatment systems.
Low-toxicity organophosphorus agent meeting environmental low-phosphorus discharge requirements for metallurgy & petrochemical cooling towers.
3.Industrial Chelating & Metal Cleaning Additive
Powerful sequestering agent to eliminate interference of Ca, Mg and heavy metal ions in industrial cleaning formulations.
Special chelating additive for textile printing & dyeing bleaching process to stabilize oxidants and improve fabric finish uniformity.
Multi-purpose complexing raw material for metal surface degreasing, rust removal and passivation treatment solutions.
