The effect of several sulfureted fatty and phosphorous type additives on the biodegradation of refined rapeseed oil was investigated.
以精制菜子油为基础油,考察了几种硫化脂肪添加剂和磷系添加剂对其生物降解性能的影响。
Taking rapeseed oil as base constituent, the three lubricant additives, ie.
以菜子油为基础油,在四球摩擦磨损实验机上分别考察了硫系添加剂T321与T307以及磷系添加剂P120对菜子油的耐磨性和极压性能的影响·结果表明,在菜子油中分别加入T321、P120和T307能够降低磨损、提高润滑油膜的承载能力和极压载荷·对钢球表面的能谱分析结果表明,在摩擦磨损过程中,含上述添加剂的菜子油在摩擦过程中发生了摩擦化学变化,生成了由菜子油三甘油酯和添加剂化学产物组成的边界润滑膜,从而改善抗磨性能并提高承载能力
The results indicate that the wear scar diameter and friction coefficient are decreased obviously and load-carrying capacity is increased when lubricated by the rapeseed oil with zine isooctoxyborate.
结果表明:在菜子油(RO)中加入异辛氧基硼酸锌以后,其承载能力明显提高,磨斑直径和摩擦因数均明显降低。
The study is extracting phospholipid from rape oil.
进行了从菜子油中提取磷脂方法的研究。

以菜子油、NaHSO_3为主要原料,以环烷酸钴为催化剂,经氧化反应等工艺过程制备新型皮革加脂剂。
?The effect of some sulfuretted fats as additives on the tribochemical properties of rape-seed oil was investigated on a four-ball friction wear tester with refined rape-seed oil taken as base oil.
以精制菜子油为基础油,在四球摩擦磨损试验机上考察了几种硫化脂肪对菜子油摩擦化学性能的影响·实验结果表明,几种硫化脂肪均能明显改善菜子油的减摩耐磨性及其极压性能·当添加剂含量较少时,其磨斑直径随添加剂含量的增加而减小,继续增加添加剂的含量,磨斑直径会明显增大·润滑油的PB值和PD值随添加剂含量的增加而提高·特别是添加剂RC2540的加入对烧结负荷影响非常明显,加入3%的RC2540,即可使PD达到7845N·扫描电子显微镜及能谱分析表明,硫化脂肪在摩擦过程中发生了摩擦化学反应,形成了一种含有活性硫元素的极压保护膜,从而起到减摩耐磨作用
