润滑油是流动的液体，像发动机机油，工业液压油，变速箱齿轮油，变压器油导热油，都属于润滑油，润滑脂俗称黄油，也属于润滑油，只是它是膏状的固体润滑油，不流淌，附着性好，主要用于轴承，齿轮等机械设备润滑，Lubricants are flowing liquids, like engine oil, industrial hydraulic oil, transmission gear oil, transformer oil, and heat transfer oil - all of these are lubricants. Grease, commonly known as butter, is also a type of lubricant, but it's a solid paste that doesn't flow and sticks well. It's mainly used for lubricating mechanical parts like bearings and gears.#润滑脂#润滑油#润滑脂工厂#润滑脂贸易 - @mt.nh.my.bi.trn
