在润滑油中加入HG—9极压抗磨剂,并以原基础油为对照在四球试验机、齿轮试验机和Falex摩擦磨损试验机上进行了一系列抗磨性能的测试,并检验了加入HG—9剂前后润滑油的各理化性质。结果表明:HG—9剂为优良的兼具抗磨和减摩作用的添加剂,加入该添加剂后,润滑油的理化指标合格。 HG-9 extreme pressure anti-wear agent was added into the lubricating oil, and a series of anti-wear properties were tested on the four-ball testing machine, gear testing machine and Falex friction and wear testing machine based on the original base oil. -9 before and after the lubricant physical and chemical properties. The results show that: HG-9 agent is an excellent anti-wear and anti-friction additives, adding the additive, the physical and chemical indicators of lubricating oil qualified.
