Summary:
   Polymaleic acid is low molecular weight polycarboxylic acid electrolyte which is high effective and organic scale inhibitor produced from water solvent. Good scale inhibition in the boiler thermonatrite medium (pH is 9~ 11.5) and the high temperature (300℃). It doesn’t evaporate with steam, not pollute the steam, good effective with organic phosphoric acid or organic sulfonic acid coordinate.
