核电站用559吨丙烯酸反应器内壁清洗转化皮膜防锈处理剂
摘要：
本发明公开一种核电站用559吨丙烯酸反应器内壁清洗转化皮膜防锈处理剂，所用原料及质量百分比如下：质量百分比浓度85%的磷酸30~50%、氧化锌1~3%、柠檬酸1~3%、酒石酸1~3%、硝酸镍2~4%、重铬酸钾1~3%、钼酸铵1~3%、三乙醇胺6~12%、乙二醇单丁醚1~3%、喷淋脱脂除油专用低泡表面活性剂1~3%及水余量。本发明与现有技术相比，只需采用高压耐酸泵将处理剂喷射1~4小时对559吨丙烯酸反应器内腔的11米长的管子内壁进行清洗。清洗的同时即可实现防锈功能，无需在下道工序中单独进行防锈处理，工艺简单、成本低，尤其是防锈时间长，可达30天以上。
摘要（英）：

The invention discloses a treating agent for cleaning and performing coating conversion and rust prevention on inner wall of a nuclear power plant used 559-ton acrylic acid reactor. The treating agent comprises the following raw materials by mass percent: 30-50% of phosphoric acid with the mass concentration of 85%, 1-3% of zinc oxide, 1-3% of citric acid, 1-3% of tartaric acid, 2-4% of nickel nitrate, 1-3% of potassium dichromate, 1-3% of ammonium molybdate, 6-12% of triethanolamine, 1-3% of ethylene glycol monobutyl ether, 1-3% of a spraying degreasing oil-removing special low-foaming surfactant, and the balance of water. Compared with the prior art, only a high-pressure acid proof pump is needed to be adopted to spray the treating agent for 1-4 hours to clean the inner wall of a pipe with the length of 11 m in the inner cavity of the 559-ton acrylic acid reactor; the rust prevention function can be achieved while cleaning, so that the rust prevention treatment is not needed to be implemented in the next procedure independently, therefore, the process is simple, the cost is low, and particularly, the rust prevention time which can last for 30 days above is long.
