YK-2002A scale inhibitor dispersant, water-soluble high-performance scale inhibitor and dispersant, its main component is polymaleic anhydride copolymer, under severe conditions such as high temperature, high pH, high alkalinity and high hardness,it have remarkable effect on calcium carbonate and sulfuric acid scale inhibition.the decomposition temperature above 300C, general PAA, PMAA and other organic copolymerization dispersing agents can not achieve the result, and the oxidation resistance is good. When add oxidizing biocide, it will not be oxidatively decomposed and loses its efficacy.
