First, the function and use 

      It is by the organic phosphine acid, gathers the carboxylic acid, the carbon steel corrosion inhibitor and the copper corrosion inhibitor duplicate matches becomes, in the adding water calcium carbonate, the calcium sulfate, the calcium phosphate and so on have the very good chelated dispersion, and to the carbon steel, the copper has the good inhibition effect. It mainly uses in the circulating cooling aqueous system inhibition anti- filthy, like circulating cooling aqueous systems and so on power plant, chemical plant, petrochemical, steel and iron, it is of inhibition effect good, anti- filthy strength. 
 
        Second, quality specification DL/806-2002 

 phosphorous acid (by the PO₃^3- ) <= 6.8
orthophosphoric acid (conform to PO₄^3-)  % <=  0.75 
 solid content % >= 32.0
PH (1% peroxide solutions)  3.0±1.5 
  density 20℃(g/cm3) >= 1.15 
 
 
        Third, application method
 
  We will need every day joins the plastic to add the medicine barrel (or box), may thin up after the convenience use or passes the regulating valve goalkeeper medicament with the metering pump inThe circulating pump entrance (i.e. water collecting header exit) joins continuously. Adds the medicine density is generally 5~20ppm (supplements watermeter).

       Forth, package and storage 
 
Its package is 25kg or 250kg plastic drum, or according to the user's  need. Stored in a cool dry place, storage period is 12 months.
