防锈乳化油因其具有良好的润滑性、防锈性、冷却性、清洗性一直是应用最为广泛的金属加工液品种之一,但传统防锈乳化油多含环烷酸盐、壬基酚等环境限制类添加剂,对环境及人体造成了威胁。本文优选各类环保添加剂,通过复配防锈剂、乳化剂、杀菌剂等功能添加剂,研制出一款具有良好的润滑性、防锈性的环保改进型防锈乳化油。 相似文献

高碱性磺酸盐复合钙基润滑脂的研究进展 总被引:1,自引:0,他引:1
高碱性磺酸盐复合钙基润滑脂是一种高温多效润滑脂,自20世纪80年代问世以来,已经在国内外获得迅速发展。这类润滑脂适合用在高温、重负荷、水淋、防锈等场合,已经在冶金、造纸、化工、汽车等领域获得良好应用。文章综述了高碱性磺酸盐复合钙基润滑脂的研究历程、制备方法、性能及应用,将有助于认识和了解这类润滑脂。同时还对高碱性磺酸盐复合钙基润滑脂下一步的研究重点和发展方向进行了分析和展望,希望能促进对该类润滑脂的研究和应用。 相似文献

The uninhibited lube oil base stocks, not containing rust inhibitors, were found to have different rust preventive properties. To differentiate between uninhibited base stocks, the ASTM D 665 rust test procedure was modified to slow down the rust formation process and a more accurate evaluation of rust formation was used. The uninhibited hydrocracked base stock was found not as effective as the mineral base stock, the white oil and synthetic polyalfaolefin (PAO) in preventing the rust formation. The hydrocracked base stock was found to be less effective in preventing rust formation and it was also found to have a significantly higher oil/water interfacial tension. A decrease in the oil/water interfacial tension is required to delay the wetting of the metal surface. 相似文献
