本文介绍了一种根据光电比色原理来评定防锈油缓蚀性能的新方法。这种方法的优点在于可作定量分析且能得出腐蚀量随时间变化的规律,此外还由于这种方法装置简单,操作方便,结果可靠,消除了肉眼造成的人为误差。因此,它是研究防锈油在盐溶液浸渍下对金属保护性能的评定和筛选防锈油缓蚀剂的一种很有使用价值的新方法。
This article presents a new method for evaluating the corrosion inhibition of rust-preventive oils based on the principle of photoelectric colorimetry. The advantage of this method is that it can be quantitatively analyzed and the law of the amount of corrosion changes with time can be obtained. In addition, because the method is simple, easy to operate and reliable, the artificial error caused by the naked eye is eliminated. Therefore, it is a very valuable method to evaluate the protection performance of anti-rust oil in salt solution impregnation and to screen the anti-rust oil corrosion inhibitor.
