Multipurpose Grease A lubricating grease suitable fOr a variety Of applications such as chassis, wheel bearings, univer—sal joints and water pumps On automotive equipment.
多用途润滑脂 指适合多种用途的润滑脂,如:车辆设备中的底盘、车轮轴承、万向节和水泵等的润滑。
Multiviscosity An Oil that meets the low temperature viscosity limits Of one 0f the SAE W numbers as well as the 100℃ viscosity limits Of,the non—W numbers.
多级粘度 既能达到SAE W前边的数字(如:5、10或15等)的低温粘度极限,同时又能达到SAE W后边的数字(如:30、40或50等)100粘度极限的油品。
Naphthenic having the characteristics Of naphthense,which are saturated hydrocarbons containing molecules with at least one closed ring Of carbon atoms.
环烷烃 具有环烷特性的、至少包含一个碳原子闭链的饱和烃。
NLGI Classficat Numbers A series Of numbers used tO classify the consistency(hardlless)Of a grease, based On a standard ASTM cone penetration test.
NLGI级数 根据ASTM针入度测试,用于划分润滑脂稠度(硬度)的——系列数字。
NLGI Service Classification System A system Of letter designations to define class Of automotive chassis and wheel bear-ing greases.
NLGI用途分类体系 用于定义机动车底盘和车轮轴承润滑脂分类的字母代号体系。
Oxidation Stability Ability of alubricant to resist oxidation and deterion resulting from high temperatues and/or ex—posure to air.
氧化稳定性 润滑油抵抗因高温和/或空气作用而氧化或变质的能力。
润滑脂就是将稠化剂分散于基础润滑油中所组成的一种稳定的固体或半固体产品。润滑脂在使用或长期储存中会有少量的油析出,这种现象称为分油,分油的多少由胶体稳定性所决定,是衡量润滑脂好坏的指标之一。
