９４─０２０丹宁酸对中碳钢腐蚀的影响在压力釜和实验锅炉上，用物理化学方法研究了丹宁酸对锅炉系统中碳钢腐蚀的影响。发现在ｐＨ１１时，丹宁酸同肼和亚硫酸钠一样，是一种良好的除氧剂，它可以抑制常温常压下和高温高压下的中碳钢腐蚀，最高缓蚀率达９７％。丹宁酸抑... 94─020 Effects of Tannin on Corrosion of Medium Carbon Steels The effect of tannic acid on the corrosion of carbon steel in boiler systems was studied using physico-chemical methods on autoclave and experimental boilers. It was found that at pH 11, tannin, like hydrazine and sodium sulfite, is a good oxygen scavenger which inhibits the corrosion of medium carbon steel at normal temperature and pressure and at high temperature and pressure with a maximum corrosion inhibition rate of 97%. Tannic acid suppression ...
