Acrylic acid-itaconic acid copolymer cleaning agent
[Structural formula]
[Physical and chemical properties] Acrylic acid-itaconic acid copolymer is prepared by copolymerizing acrylic acid and itaconic acid in the presence of an initiator
[Preparation]
(1) The raw materials are acrylic acid (the polymerization inhibitor is purely removed before polymerization), itaconic acid, deionized water, and ammonium persulfate
(2) US patent US5032646 discloses a method for preparing acrylic acid itaconic acid copolymer
(3) The raw materials are 50~90mL of itaconic acid, 10~50mol of acrylic acid, 1%~2% of sodium persulfate (based on the total mass of monomers), and 6%~12% of sodium bisulfite (based on the total mass of monomers) ), ferrous sulfate 0.
[Application] Itaconic acid/acrylic acid copolymer (composition mass ratio 90:10), used for on-line cleaning of circulating cooling water system, can effectively remove thick scale layer (0.
