摘要
润滑脂的性能是确保钢丝绳使用寿命的关键。对七种常见的钢丝绳润滑脂的理化特性进行探究,测定七种润滑脂的灰分、残碳、水分、比重、粘度、防水性、抗氧化性、抗腐蚀性等理化指标,辅以图表法、观察法等手段,对比润滑脂的质量与功能。研究发现:1)从成分测定结果看,杂质少、不易结块的润滑脂为KL-90、KL-70、XT-70,不易积碳的润滑脂为CH-1、IRIS655、A19-200,低温流动性最好的润滑脂为XT-70;2)从物理性质测定结果看,七种润滑脂在流动性和防水性方面差异不大,适用温度宽度大的润滑脂为KL-90;3)从化学性质测定结果看,抗氧化性、抗腐蚀性最好的润滑脂均为IRIS655。分析了不同润滑脂理化指标之间的内在关联,明确了各种润滑脂在不同环境下的适用性。
The performance of lubricating greases is the key to ensure the service life of wire ropes.By studying on the physical and chemical properties of 7 common lubricating greases for wire ropes,the physical and chemical indexes of 7 lubricating greases,such as ash,residual carbon,moisture,specific gravity,viscosity,water resistance,oxidation resistance and corrosion resistance were determined,and the quality and function of lubricating greases were compared by auxiliaries of chart and observation.Findings:1) According to the results of composition determination,lubricating greases with few impurities and caking resistance are KL-90,KL-70 and XT-70,lubricating greases with carbon deposition resistance are CH-1,IRIS655 and A19-200,and lubricating grease with the best low-temperature fluidity is XT-70.2) From the measurement results of physical properties,7 lubricating greases have little difference in fluidity and water resistance,in which KL-90 is the lubricating grease with wide applicable temperature.3) According to the measurement results of chemical properties,the lubricating grease with the best oxidation resistance and corrosion resistance is both IRIS655.The intrinsic relationship between the physical and chemical indexes of different lubricating greases was analyzed,and the applicability of various lubricating greases in different environments was ascertained.
