研究了根据有关技术标准进行生产的清洗剂及其清洗活性和脱脂性能。在分析试验结果的基础上 ,研制出了一种通用的清洗剂。这种溶剂无毒、不燃、不爆 ,能彻底被生物降解且应用广泛 ,其成分中含有表面活性剂和能去除铝合金表面的油污及氧化层。此外 ,制定了铝合金构件焊前表面处理的合理工艺。 The cleaning agents produced according to the relevant technical standards and their cleaning activity and degreasing properties were studied. Based on the analysis of test results, a general cleaning agent has been developed. This solvent is non-toxic, non-flammable, non-explosive and can be thoroughly biodegraded and widely used. Its ingredients contain surfactants and oils and oxides to remove aluminum alloy surfaces. In addition, developed a reasonable process of welding aluminum alloy surface before welding.
