摘要
本文研究了防冻液中多金属高温下的缓蚀剂.并介绍了优选出的组合缓蚀剂NSH-Ⅱ的性能及应用.由NSH-Ⅱ缓蚀剂配制的防冻液对铸铁、钢、铜、黄铜、铸铝、焊料具有良好的保护作用.ASTM D1384腐蚀试验后六种金属均不产生孔蚀.
Inhibitors of many kinds of metals in antifreeze were studied. The properties and application of NSH- I inhibitors selected were introduced. The antifreeze with the inhibitors protects cast iron, stool, cast allumium, solder, copper and brass from corrosion. There was not any pitting corrosion on the sin kinds of metals after ASTM D1384 corrosion test.
