| meaning, pronunciation, translations and examples. A lubricant is a substance, usually organic, introduced to reduce friction between surfaces in mutual contact, which ultimately reduces the heat generated when the surfaces move. Generally speaking, the lighter the oil, the easier it will spread around and permeate through surfaces, making it potentially more toxic for the environment.
Lubricants are regulated internationally and locally, e.
Toxicity refers to how harmful an oil might be to humans, other living organisms, and the environment. Lubricants are developed using base oils produced from crude oil refining by adding additives according to mixing ratio for each use or developed by compounding chemicals such as pao.

Volume i application and maintenance, second edition (handbook of lubrication (theory & practice of tribology)). Mineral oils (petroleum oils) are products of refining crude oil. Petroleum classification is related to the geographical region where it is extracted. Viscosity classification.high viscosity usually means better protection for wear.low viscosity usually means low friction resistance. | meaning, pronunciation, translations and examples.
