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 ***0mg/l. It often cooperates
with dispersion-scale inhibitor in the use.
