APPLICATIONS:
can be wide used for industrial treatment water as corrosion and scale inhibitor, for example boiler water, cyclic cooling water and water of oil field. In addition, it is used as complexing agent in no cyanide electroplating, as metal cleaner and as stabilizer and fixation in blanch and dye industry. As the scale inhibitor ,it can well inhibit the scale of calcium carbonate. The adding weight concentration of active ingredient is 1-10mg/l. It often cooperates with dispersion-scale inhibitor in the use.
