摘要：The acid activated vermiculite (HVerm) was prepared and utilized to react with maleic anhydride (MA) and acrylic acid (AA) to synthesize a novel HVerm/MA/AA copolymer was prepared through free-radical polymerization in aqueous solution. The chemical structure of HVerm/MA/AA was confirmed by Fourier transform IR, X-ray diffraction analysis and SEM micrographs. Using the static experiment method, the influences of copolymer concentration, temperature, time and Ca2+ concentration of the system on the inhibition efficiency were investigated. The experimental results showed that the scale inhibitor copolymer modified with vermiculite (Verm) had an excellent efficiency of scale inhibition, and 98.34% of scale inhibition efficiency for CaC〇3 was obtained. The prepared scale inhibitor could be used in the system of high temperature and high hardness water.
