摘要
丙二醇是1种微毒化合物,在许多欧洲国家被广泛应用于发动机冷却液的调配。对丙二醇(MPG)与乙二醇(MEG)这2种化合物的热传导性、冰点防护性、气穴腐蚀性、橡胶相容性及毒性等方面进行比较,结果证明MPG 非常适用于发动机冷却液的调配。
Mono-propylene glycol(MPG) is a favorable properties compound。In a number of European countries,it is used as a material for automotive engine coolant formulation.In this article,we compared propylene glycol with ethylene glycol on the heat transfer characteristics,freezing protection,cavitation and erosion-corrosion, rubber compatibility。It is proved that the very bland characteristics of MPG offer coolant formulations based on this glycol significant advantages.
