    • PROBLEM TO BE SOLVED: To provide an anticorrosive which can more efficiently maintain the pH of the boiler water and thus prevent not only corrosion of the inside of a boiler can but also corrosion of the entire boiler system including feed water (condensed water), without a need for adding a large amount of a phosphate or increasing the molar ratio Na/POto 3 or greater, mainly in a boiler provided with a superheater or a steam turbine, or the boiler is mixed a boiler water with treated water.SOLUTION: The anticorrosive for a boiler comprises an amine compound represented by general formula (1), and the anticorrosive for a boiler comprises a deoxidizing agent together with an amine compound represented by general formula (1): NH-(CH)-O-(CH)-OH (1), wherein m and n each independently represent an integer of 1-3.
    • 要解决的问题:提供可以更有效地保持锅炉水的pH的防腐剂,并且因此不仅防止锅炉内部的腐蚀,还可以防止整个锅炉系统的腐蚀,包括给水(冷凝水 ),不需要添加大量的磷酸盐,或者将Na / PO 4 的摩尔比增加到3以上,主要是在设置有过热器或蒸汽的锅炉 涡轮机或锅炉将锅炉水与处理过的水混合。 解决方案:锅炉的防腐蚀剂包括由通式(1)表示的胺化合物,锅炉的防腐蚀剂包括脱氧剂和由通式(1)表示的胺化合物:NH 2 - (CH 2 m -O-(CH 2 )其中m和n各自独立地表示1-3的整数。 版权所有(C)2012,JPO&INPIT
