第五章润滑脂一、润滑脂的组成润滑脂是由润滑油和稠化剂再加入改善性能的添加剂所制成的一种半固体(通常是油膏状)的润滑剂,其组份有基础油、稠化剂、稳定剂和添加剂。基础油是润滑脂中含量最多(占79～90%)的组份,是起润滑作用的主要物质。矿物油和合成油都可作基础油。矿物油是制造普通润滑油的主要基础油,价格低,但使用温度范围较窄,不能同时满足高、低温要求。 Chapter V Grease I. Composition of Grease Grease is a semi-solid (usually oily) lubricant made of lubricant and thickener followed by additives to improve performance. Its components are Base oils, thickeners, stabilizers and additives. Base oil is the most abundant grease (79 ~ 90%) of the component, is the main material from the role of lubrication. Mineral oil and synthetic oil can be used as base oil. Mineral oil is the main base oil for the manufacture of ordinary lubricants. The price is low, but the service temperature range is narrow, so it can not satisfy both high and low temperature requirements.
