摘要
分析了影响润滑脂中游离碱测定的主要因素。试验表明,测定润滑脂中游离碱的溶解温度应为75℃左右,水解后应冷却到室温再进行滴定,同时滴定溶剂的含量也应适当。
It was analyzed the primary influence factors of determining free alkali in greases. The tests showed that the dissolving temperature should be about 75℃ of determining free alkali in greases, and should be cooled to room temperature and then titrated after hydrolysis,while the contents of the titration solvent should also be appropriate.
