GB/T 12691-2021空气压缩机油新国标的解读

Interpretation of the New Version of Air Compressor Oils (GB/T 12691-2021)

文章介绍了GB 12691国标修订背景以及内容发生的重大变化,对关键指标,如黏度级别、黏度指数、抗泡性、抗乳化性、氧化安定性等性能,结合空气压缩机油的实际应用情况做了详细解读。新国标不仅适用于矿物型空气压缩机油,还适用于半合成、全合成型的空气压缩机油,这也顺应了目前合成油在空气压缩机油市场的占比不断增加的发展趋势,新国标的应用将整体提升空气压缩机油的质量水平。

This paper introduces the background for the revision of the national standard GB 12691 as well as major changes to its content.Key indicators,such as viscosity grade,viscosity index,anti-foaming,anti-emulsifying,and oxidation stability,were expounded,in combination with the practical applications of the air compressor oil.The new version is applicable to mineral-based air compressor oils,and also to semi-synthetic and full-synthetic air compressor oils,which conforms to the development trend that the proportion of synthetic oils in the air compressor oil market will continue to increase.The application of the new version will improve the quality level of air compressor oil as a whole.
