water-line corrosion

Advancements of phosphate-free corrosion inhibitors for circulating cooling water system

循环冷却水系统无磷缓蚀剂研究进展

The reinforced concrete structure in waste water treatment plant suffered severe corrosion.

处理污水采用的钢筋砼结构，其腐蚀是严重的。

The processing system of domestic wastewater does not require preservative treatment, but need the convert water pump with anti-corrosion. 4.

生活污水处理系统不需要进行防腐处理，只需选择耐腐蚀性的转水泵即可。

The pH of the effluent from the ion exchange mixed bed is in the range of 7.60 to 8.95. The copper tested before and after the small exchange column shows that the cooling water treated by resin has an obvious effect on restraining copper corrosion.

离子交换柱之前和之后的铜试片试验结果显示：交换柱前的内冷水具有腐蚀性，而经交换柱处理后的内冷水具有抑制铜导线腐蚀的功效。

Corrosion The corrosive degree of specimen in neutral salt spray test for 200h was the same as one in coal mine water for a year.

200h中性盐雾试验相当于煤矿水质一年的腐蚀量。
