对侵蚀性CO2>68.2mg/L为弱腐蚀的评价提出质疑。为此该文根据有关的两规范的专业性质对普通酸与碳酸的腐蚀速度、西双版纳州水质的特点、碳酸腐蚀强度定级方法等,作了初步分析。两规范评价虽然强弱不同,实际论证并无差别,仅在腐蚀强度定级方法上有差别,如:侵蚀性CO2>40mg/L为弱腐蚀的标准,达到弱腐蚀状态,是有时间的,没有给出时间是不完善的。
The evaluation of corrosive CO2> 68.2mg / L as weak corrosion was questioned. Based on the professional nature of the two specifications, this paper made a preliminary analysis of the corrosion rate of common acids and carbonic acid, the characteristics of water quality in Xishuangbanna and the grading method of carbonic acid corrosion strength. Although there are differences between strength and weakness of the two norms, there is no difference in the actual demonstration. Only differences exist in the method of grading the corrosion intensity, for example, the erosive CO2> 40mg / L is the standard of weak corrosion, Not given time is not perfect.
