高碱值环烷酸钙在SE 10W/30汽油机油中的应用(环烷酸钙经济配方)

THE APPLICATION OF OVERBASEI CALCIUM NAPHTHENATE IN SE 10W/30 GASOLINE ENGINE OIL(THE ECONOMIC FORMULATION OF CALCIUM NAPHTHENATE)

介绍厂以新疆原油生产的中性油为基础油，以国产高碱值环烷酸钙为主要清净剂，加入适量的分散型粘度指数改进剂，与其它添加剂适当配伍研制生产ＳＥ１０Ｗ／３０汽油机油的过程。经理化性质分析，ＭＳ程序ⅡＤ、ⅢＤ、ＶＤ及Ｌ－３８发动机台架评定，该油品性质完全符合ＧＢＩ１１２１－１９９５指标要求。

By taking the neutral oil produced from Xinjiang crude oil as base oil and domestic overbased calcium naphthenate as main detergent, added proper dispersion type VII and other compatible additives, SE 10W/30 gasoline engine oil has been developed. The analysis on physicochemical characteristics and the bench evaluation of MS sequence II D, III D, V D and L- 38 showed that this oil's performances can completely meet the requirements of GB1 1 121 - 1995 specification.
