Study on anticorrosive property and synthesis of AA/MA/AMPS copolymer scale inhibitor

Using water as solvent,sodium hypophosphite and peroxide as initiator,iron salts as catalyst,maleic anhydride(MA),acrylic acid(AA) and 2-acryloyl amino-2-methyl propane sulfonic acid(AMPS) as monomers,through aqueous solution polymerization method,the synthesis of AA-MA-AMPS three copolymer resistance scale dispersant,and its performance were studied.Results showed that with concentration of 2.5 - 20 mg/L AA/MA/AMPS copolymer scale inhibitor and HEDP,HPMA agent on the deposition of CaCO3 maximal inhibition ability is respectively 96%,77.8% and 88.4%,AA/MA/AMPS copolymer scale inhibitor has good scale inhibition performance.
