D-765-A/B/C高效船舶柴油机汽缸油
产品简介:
D-765是专为船舶而开发的十字头柴油机汽缸油,能为在严苛条件下燃烧高硫份燃油,高动力柴油机提供极佳的保护,对此等特殊结构的船舶发动机能满足其所有汽缸润滑之要求。
特殊效益:
*在接触水(含海水)时,具极强的抗乳化性
*具有绝佳的重负荷润滑性以保证汽缸和活塞环之间的完美润滑
*具有足够的清净分散性能,以保证其对活塞环带,活塞及气口之清洁功效
*具高度的酸中和能力,以中和因燃烧而产生的硫酸和硫化物,提供良好的抗
腐蚀性能
*具优异的密封性能,以保证燃烧气体不窜过汽缸套和活塞环间的空隙
*具良好的储存稳定性
用途:
极适用于船舶高动力在严苛工作条件下使用高硫份燃油之船舶十字型柴油机汽缸润滑。
