Title: Method for inhibiting corrosion of metal in water line
Inventor: KUROBE HIROSHI
IPC: C02F1/42
Filed: 1994-05-18
Abstract: PURPOSE:To prevent the formation of scale in a resin column when the corrosion of a metal in a water line is inhibited by treatment with an anion exchange resin. CONSTITUTION:A low mol.wt. polymer 11 is added to corrosive ion-contg. water in a water line or corrosive ion-contg. water fed to the water line and the water is brought into contact with a highly basic anion exchange resin 2 with carried anticorrosive anions in a resin column. The formation of scale in the column is prevented by the scaling inhibiting action of the polymer 11 and the passing of water through the column can be stably and efficiently continued over a long period of time. The polymer 11 does not affect the ion exchange performance of the resin and effectively produces anticorrosive film forming and scaling preventing effects in the water line because it migrates to ion exchange treated water without adsorption on the resin.
