| titleOfInvention | The processing method of cooling water system |
| abstract | The present invention provides a kind of medicament for not adding high concentration in the cooling water system of the water low and low flow velocity using calcium hardness and the processing method of the cooling water system of the corrosion that prevents metal parts.The present invention relates to a kind of processing methods of cooling water system, its to the calcium hardness with cooling water be 150~300mg/L, and the flow velocity of cooling water is that (methyl) acrylic acid series copolymer is added in the cooling water system of the position of 0.3~0.5m/s, wherein, (methyl) acrylic acid series copolymer has the structural unit (a) from specific (methyl) acrylic monomer (A) and the structural unit (b) from specific (methyl) allyl ether system monomer (B), the content of structural unit (b) is 15 moles of %~20 mole % in the 100 moles of structural units of % from whole monomers, the weight average molecular weight of (methyl) acrylic acid series copolymer is 10000~30000, at least one main chain terminal is sulfonic group, or its salt. |
