石油产品铜片腐蚀试验结果判定方法的改进初见

IMPROVEMENT ON THE EVALUATION OF COPPER CORROSION BY PETROLEUM PRODUCTS IN COPPER STRIP TEST

现行铜片腐蚀试验法是以油样颜色变化对石油产品进行评价 ,这种方法存在着一定的不科学和不完善性。本文根据油样的颜色变化与铜离子浓度有关的原理 ,提出了铜离子浓度作为描述铜片腐蚀结果指标的初见。

The result of copper strip test, a test of copper corrosion by petroleum products, is currently evaluated by the color changes of the copper strip and petroleum products sample The present method shows unscientific sense and less accuracy This article proposes a new method to evaluate the copper corrosion by petroleum products by means of quantitative analysis of the cupric ion in the petroleum sample Based on the principle that samples color is related to the concentration of cupric ion, the new method can offer quantitative evaluation on the corrosion with more accuracy
