摘　　要：研究了一种常温下使用的化学脱脂剂。结果表明,氢氧化钠10g/L、硅酸钠8g/L、碳酸钠6g/L、多聚磷酸钠5g/L、焦磷酸钠1g/L、柠檬酸钠8g/L、磷酸钠10g/L、十二烷基苯磺酸钠12g/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, lhe results snow that wnen 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.
