ZHQ-CSIA-01 Corrosion and Scale Inhibitor

  ZHQ-CSIA-01 Corrosion and Scale Inhibitor is an organic polyphosphonic acid water treatment agent. It features excellent chemical stability and is resistant to hydrolysis. With outstanding chelation and threshold inhibition effects, it prevents scale-forming salts in water from generating water scale. It provides favorable corrosion inhibition for carbon steel, and has good compatibility with various water treatment chemicals, enabling the formulation of multiple water treatment formulas.
  It is widely applied for corrosion and scale inhibition treatment of circulating cooling water, boiler water and oilfield injection water in metallurgy, chemical, power generation and other industries; it can also be used as metal cleaner in electroplating industry.
