目前,国内科研单位都是利用玻璃器皿腐蚀实验(SH/T 0085)来测试发动机冷却液的性能,在国外已经引用电位测试法(ASTM D 1384)来研究。其主要是将有机酸型缓蚀剂、有机非酸型缓蚀剂和无机盐型缓蚀剂进行优化复配,筛选出了一种对汽车冷却系统多种金属有全面保护的高性能的冷却液配方,尤其对焊锡和铸铝的保护性能更为突出,适合现代汽车工业冷却系统向铝合金方向发展的需求。
At present, the domestic research institutes all use the corrosion test of glassware (SH / T 0085) to test the performance of engine coolant. In foreign countries, the reference potential test (ASTM D 1384) has been used to study. Its main is organic acid corrosion inhibitor, organic non-acid corrosion inhibitor and inorganic salt type corrosion inhibitor optimized compound, screened a car cooling system for a variety of metals with comprehensive protection of high-performance cooling Liquid formulations, especially for the protection of solder and cast aluminum are more prominent, suitable for the modern automotive industry cooling system to the direction of the development of aluminum alloy needs.
