윤활유(lubricating oil)란?

윤활유(lubricating oil)는 기계 부품 사이의 마찰을 줄이고 열을 분산시키는 데 사용되는 점성이 있는 액체입니다. 윤활유는 기계의 부품이 움직일 때 마찰로 인한 손상을 방지하고, 과열을 막으며, 부품의 수명을 연장하는 역할을 합니다.

윤활유는 주로 석유에서 추출되지만, 생물학적 원료로부터 얻어지는 바이오 베이스드 윤활유와 화학적으로 합성된 합성 윤활유도 있습니다. 윤활유는 자동차 엔진, 산업용 기계, 가정용 기기 등 다양한 용도로 사용됩니다.

윤활유의 종류는 다양하며, 각기 다른 점도, 충격 흡수 능력, 내화성, 내식성 등의 특성을 가질 수 있습니다. 특정 윤활유의 선택은 해당 기계와 작동 조건에 따라 달라집니다.

 

A lubricating oil is a viscous liquid used to reduce friction between machine parts and dissipate heat. When parts of a machine move, lubricants prevent damage from friction, prevent overheating, and extend the life of the parts.

Lubricants are primarily derived from petroleum, but there are also biobased lubricants, which are obtained from biological sources, and synthetic lubricants, which are chemically synthesized. Lubricants are used in a variety of applications, including automobile engines, industrial machinery, and household appliances.

There are many different types of lubricants, and they can have different viscosities, shock absorption capabilities, fire resistance, corrosion resistance, and other properties. The choice of a particular lubricant depends on the machine and its operating conditions.
