Abstract:
     This invention relates to a new-type compounded alkaline water treating agent used in cyclic heat supply or cooling systems for preventing dirt, rust, algae and water loss in the apparatus and removing scale. Polysilicate, ammonium trimethylene potassium-sodium phosphate and water-soluble sodium humate are used to replace the silicate, ammonium trimethylene phosphonic acid, potassium carbonate and sodium humate in original type of the treating agent. The cathode film-forming agent (Zn salt) and the hydroxyethylene potassium-sodium diphosphate that has high power to control carbonate are additionally used. This improved chemical can also be used for preventing scale in small-size low-pressure steam boiler and features no toxic and no environmental pollution.
