随着机械产业的高速发展,润滑脂就应用范围来讲其广泛程度已远远超过了润滑油等其他润滑剂,而其应用技术要求的不断提高也促使润滑脂本身在不断地进行更新换代,如钙基脂等正逐渐被综合性能更好的锂基脂所取代,具有多种优良性能的复合皂基脂及聚脲基脂等也得到了较快发展。表1所列出的是全美润滑脂协会(NLGI)成员单位及我国1993年度润滑脂产品构成的对比情况。
With the rapid development of machinery industry, grease in terms of its scope of application has far exceeded the other lubricants and other lubricants, and its application of the continuous improvement of technology also prompted the grease itself constantly in the process of replacement, Such as calcium-based fat, etc. are gradually being replaced by the better overall performance of lithium-based grease, with a variety of excellent performance complex soap base fat and polyurea fat also has been rapid development. Table 1 lists the composition of the National Association of Lubricants (NLGI) member and China’s grease products in 1993 compared to the composition.
