Synergistic scale inhibition of both IA/AMPS copolymer and magnetic field

Abstract

The antiscaling rate of both water magnetic device and IA/AMPS copolymer was investigated by using a stationary scale inhibition experimental device, and the result illustrated that there was a synergistic scale inhibition effect between magnetic field and IA/AMPS copolymer. Under the condition the experimental water through the water magnetizer was 120L / h, and the magnetic field strength was 0.7T, the magnetization time of 40 min, the antiscaling rate of both water magnetic device and copolymer IA/AMPS to CaCO3 increased 11% as compared with that of the copolymer IA/AMPS alone. At this time, the dosage of copolymer IA/AMPS was 6mg/L. And the synergistic antiscaling rate of both water magnetic device and IA/AMPS copolymer to Ca3(PO4)2 increased 25% as compared with that of the copolymer IA/AMPS alone under the same condition except dosage of IA/AMPS copolymer was 20 mg/L.
