摘要

A new composite type of industrial corrosion and scale inhibitor of maleic anhydride-acryl amide copoly merattapulgite was developed, when water was solvent, hydrogen peroxide was initiator, maleic anhydride (MA) and acrylamide were monomers, and hot acid treated attapulgite clay was added into the polymerization system. Its scale and corrosion inhibitions were evaluated by methods of static test and rotary weight loss test. For further study, modification temperature and acidity, stirring time, and adding dosage of attapulgite clay on the scale inhibition performance of copolymer were investigated, as well as the corrosion inhibitory property of the final product. Results showed that, the copolymerization conditions were: modified attapulgite clay after 300 ¡æcalcination and 4% hydrochloric acid 0.05 g, maleic anhydride2.7 g, acryl amide 1.525 g, hydrogen peroxide 1 mL, water 9.9mL, reaction temperature 60 ¡æ, and stirring time 100 min. Under these conditions, the high test anti-scaling rate was85.68% that was improved by 73.40%, and the corresponding corrosion rate was 0.093 mm/a that was improved by 26.2%. The composite type of industrial corrosion and scale inhibitor prepared with hot acid treated attapulgite clay possesses advantages of new-type, efficient, economical and phosphate free, and proves potential application prospect in industrial circulation cooling water treatment.
