水基金属加工液用消泡剂的实验室及现场效果评价

Laboratory and Field Evaluation of Defoaming Agent for Water-based Metalworking Fluids

近年来水基金属加工液迅速发展、用量增大,由此产生的泡沫问题尤其突出。文章就水基金属加工液的特点,详细阐述了该行业对消泡剂性能的特殊要求及其选择方法;通过一系列的实验方法,对一种金属加工液专用消泡剂XP-5025的消抑泡性能、相容性、稳定性及现场应用效果进行了评价,结果表明,XP-5025具有良好的消抑泡性能、相容性、稳定性,适合在水基金属加工液中使用。

Water-based metalworking fluids have been developed rapidly in recent years,the consumption continues to increase.As a result,foam problem is particularly prominent.In this paper,based on the characteristics of water-based metalworking fluids,the special requirements for defoamer performance and selection methods of defoamer in this industry are described in detail.Through a series of experiments,the antifoaming performance,compatibility,stability and field application effect of the defoamer XP-5025 which is a special defoamer for water-based metalworking fluid are evaluated.The result shows the defoamer XP-5025 has good antifoaming performance,compatibility and stability in field application.It is a suitable defoamer for the application of water-based metalworking fluid.
