RJ-1溶剂型飞机清洗剂应用研究

摘要

Objective To study the validity of the RJ-1 non-aqueous aircraft cleaner applied in aircraft maintenance/repair. Methods Referring to the requirements and measuring methods from the American military specification of MIL-PRF-32295, the physical-chemical properties, performing characteristics, prohibition for aircraft metals, as well as compatibility with non-metal materials of the RJ-1 non-aqueous aircraft cleaner developed by ourselves were evaluated. Results The flash point of the RJ-1 non-aqueous aircraft cleaner was above 60℃, and it is safe to use, transfer and store. The cleaning efficiency of the cleaner was not lower than 90%. It was easy to dry and didn′t leave any nonvolatile residue. The cleaner effectively inhibited corrosion of metal materials, and would not cause corrosion of aircraft metals. Moreover, it was satisfactorily compatible with non-metal materials such as surface coatings of the aircraft, acrylic plastics, insulated wire, rubber and sealant. Conclusion The RJ-1 non-aqueous aircraft cleaner satisfies the requirements of aircraft cleaning, and can be applied in the aircraft maintenance/repair.%目的：研究RJ-1溶剂型飞机清洗剂应用于飞机维护/维修的有效性。方法参照MIL-PRF-32295的要求及测试方法，对自主研发的RJ-1溶剂型飞机清洗剂的理化性能、使用性能、对飞机上金属材料的腐蚀性以及与非金属材料的相容性进行了评价。结果 RJ-1溶剂型飞机清洗剂闪点在60℃以上，使用、运输和贮存安全；清洗效率不低于90%，并且干燥时间短，无残留；对飞机上钢、铜、铝、镁等多种金属材料有良好缓蚀作用，不会导致金属产生腐蚀；与飞机表面涂层、有机玻璃、绝缘导线、橡胶、密封剂等非金属材料相容性良好。结论 RJ-1溶剂型飞机清洗剂满足飞机清洗的要求，可以应用于飞机维护/维修。
