研究了一种常温下使用的化学脱脂剂。结果表明, 氢氧化钠10 g/L、硅酸钠8 g/L、碳酸钠6 g/L、多聚磷酸钠5 g/L、焦磷酸钠1 g/L、柠檬酸钠8 g/L、磷酸钠10 g/L、十二烷基苯磺酸钠12 g/L时, 脱脂率达到99%。试验所得脱脂剂优化配方, 较其它脱脂工艺温度有所降低, 防腐蚀、防锈性能大为提高, 还是一条经济节约、绿色环保的工艺路线。

A chemical degreasing agent used at normal temperature was developed. The results show that when optimal formulas of the degreasing agent were sodium hydroxide 10 g/L, sodium silicate 8 g/L, sodium carbonate 6 g/L, sodium polyphosphate 5 g/L, sodium pyrophosphate 1 g/L, sodium citrate 8 g/L, sodium phosphate 10 g/L, sodium 12 g/L, the skim rate reached 99%. The degreasing temperature of the agent is lower than that of other agents, and the anti-corrosion and antirust performance is greatly improved. This process route is economical and environmental.
