Abstract:

Allylpolyethoxy carboxylate macromonomers, possessing polyethylene oxygen long chains, were synthesized by advanced technology of the polyether cap. A novel double-hydrophilic block copolymer was prepared through free radical polymeric reactions in aqueous solution and its performance on CaCO₃ inhibition and dispersancy activity towards Fe₂O₃ was evaluated in recirculating cooling water systems. The study shows that acrylic acid-allylpolyethoxy carboxylate has a significant ability to inhibit the precipitation of calcium carbonate and an excellent dispersing capability to stabilize iron(Ⅲ)in industrial cooling systems. X-ray diffraction shows that there is a number of vaterite crystals in the presence of the phosphorous free and non-nitrogen copolymer. The change in crystal forms is also confirmed by the Fourier-transform infrared spectra, the scanning electron microscopy and the transmission electron microscopy. The inhibition mechanism is proposed and it shows that the interactions between calcium and polyethylene glycol(PEG)are the fundamental impetus for restraining the formation of the scale in cooling water systems.
