| Abstract: | In order to study the effect of circulating and cooling water on the performance of tri-copolymer scale inhibitor(PMAM),the static scale-inhibiting experiments with calcium carbonate were conducted in different conditions.The influence of the chemical dosage,temperature of cooling water,constant temperature keeping time,pH,alkalinity and concentration multiple,etc on the scale inhibiting rate was investigated.The results showed that the dosage of PMAM used was only 8 mg/L;the scale-inhibiting rate was the highest when pH of cooling water was 7;it possessed high thermal stability and good ageing ability;its concentration multiple was high. |
