The influence of paraffinic base oil on the performance of naphthenic base oil was investigated by studying the low-temperature viscosity of tested oils. The viscosity of lube oils increased with an increasing content of high-viscosity paraffinic base oil in the oil mixture. And the low-temperature viscosity was less influenced when the content of paraffinic base oil in the mixture was insignificant. In order to reduce the cost for formulating lubricating oil, a small fraction of paraffinic base oil can be added into naphthenic base oil as far as the property of lubricating oil can meet the specification. According to the study on low-temperature viscosity of the oil mixed with paraffinic base oil and naphthenic base oil, a basic rule was worked out for the preparation of qualified lubricating oils.展开更多
O ITA B570船用气缸油的研制成功,是澳力丹公司总结十多年生产润滑油经验和吸收世界先进技术的产物。通过配方筛选试验表明,以500SN为基础油,采用高碱值硫化烷基酚钙为主剂配以澳力丹从澳大利亚引进的O ITA减磨剂等,完全可以用石蜡基基...O ITA B570船用气缸油的研制成功,是澳力丹公司总结十多年生产润滑油经验和吸收世界先进技术的产物。通过配方筛选试验表明,以500SN为基础油,采用高碱值硫化烷基酚钙为主剂配以澳力丹从澳大利亚引进的O ITA减磨剂等,完全可以用石蜡基基础油调制出性能优良的高碱值船用气缸油。上述配方2003年通过了上海船舶科学运输研究所台架试验并在远洋船舶中开始试用。展开更多
