减磨剂是一种较新的润滑油添加剂,如美国产TMT、日本产TCL、国产101等。它的功能是降低摩擦阻力、减小机械磨损、降低能源消耗及延长发动机使用寿命。减磨剂可分为非油溶性和油溶性两大类。非油溶性减磨剂有二硫化钼、石墨,颗粒直径为φ0.05mm～φ0.5mm,能在油中保持稳定分散状态。油溶性减磨剂能溶于润滑油,种类较多, Reducer is a newer lubricant additives, such as the United States TMT, Japan-made TCL, domestic 101 and so on. Its function is to reduce frictional resistance, reduce mechanical wear and tear, reduce energy consumption and extend engine life. Antifriction agent can be divided into two categories of non-oil-soluble and oil-soluble. Non-oil-based anti-friction agent molybdenum disulfide, graphite, particle diameter φ0.05mm ~ φ0.5mm, to maintain a stable dispersion in the oil state. Oil-soluble antifriction agent can be dissolved in lubricating oil, more types,
