C-276合金带材因其优异的抗腐蚀性能被广泛用作第二代高温超导材料的金属基底,因此其表面清洗更加重要,而普通清洗剂残留较多,难以满足洗净率的要求,且传统的有机溶剂清洗剂还有易燃、有毒、价格高等缺点.为此,采用Ramis CIA清洁度检查系统优选常温、低毒、环保、安全、高效的水基清洗剂,采用正交试验优选清洗剂中各组分的最佳用量,确定了水基清洗剂的最佳组成并对清洗剂的性能进行检测.结果显示:最优水基清洗剂组成为3.5 g/L氢氧化钠,0.4 g/L辛基酚聚氧乙烯醚,5.0 g/L葡萄糖酸钠,0.3 g/L烷基聚氧乙烯硫酸酯盐,25.0g/L碳酸钠.该水基清洗剂为微黄色透明液体,在超声波条件下对C-276合金的清洗率可达100％.
C-276 alloy strip has been widely used as the metal substrate of superconducting material in the high temperature superconductivity field because of its excellent corrosion resistance.Therefore,the surface cleaning is even more important.However,the general cleaning agents have more residues,which can not meet the requirements of the washing rate.In addition,the traditional organic cleaning agents have some shortcomings such as flammable,toxic,expensive and so on.In this work,the room-temperature,low-toxicity,environmentally friendly,safe and efficient water-based cleaning agent was optimized by Ramis CIA cleanliness inspection system through orthogonal experiment to determine the best dosage of components of the cleaning agent.Furthermore,the properties of the water-based cleaning agent under the optimized conditions were measured.Results showed that the best water-based cleaning agent consisted of the sodium hydroxide 3.5 g/L,octyl phenol polyoxyethylene ether 0.4 g/L,sodium gluconate 5.0 g/L,alkyl polyoxyethylene sulfate salt 0.3 g/L and sodium carbonate 25.0 g/L,which was a kind of light yellow transparent liquid.Under the ultrasonic wave condition,the washing rate reached 100％.
