矿物油
Mineral oil is used as a lubricant, a cutting fluid, and as a conditioning oil for jute fibres selected for textile production, a process known as 'jute batching'. Spindle oils are light mineral oils used as lubricants in textile industries. Electric space heaters sometimes use mineral oil as a heat transfer oil. Because it is noncompressible, mineral oil is used as a hydraulic fluid in hydraulic machinery and vehicles.
