Scale inhibitor with chitosan

A scale inhibitor copolymer modification with chitosan was prepared from maleic anhydride, styrene sulfonic sodium, acrylic amide and chitosan. The conditions of preparing scale inhibitor were optimized. The chemical structure and thermal property were investigated. Using the static experiment method, the influences of copolymer concentration, temperature time, Ca2+ concentration, HCO3 concentration of the system on the inhibition efficiency were investigated. The experimental results showed that the polymer was excellent calcium carbonate scale inhibition and the resistance rate of calcium carbonate scale up to 95.62%, and could be used in the system of high temperature and high hardness water.
