the influence of static thermal degradation on colloidal performance of lithium-calcium base grease was studied by the centrifugal oil separation test, dropping point test and acid number test.
利用离心分油试验机、油浴滴点测定仪和酸堿滴定仪分别考察了静态热老化对锂-钙基润滑脂胶体性能的影响。
the said grease possesses high dropping point and good colloidal and shear stability as well as good anti corrosion, water resistance and anti wear properties.
制备的复合锂-钙基脂具有高滴点和良好的胶体安定性、剪切安定性,良好的抗水性、防腐性和润滑性。
the lag of domestic greases behind foreign products in variety and quality is analyzed, and a suggestion to develop multi- functional grease with higher dropping point is proposed.
分析目前国内外润滑脂品种和产品质量差距,提出发展高滴点多效能润滑脂的建议。
in this paper, newton iterative formula based on deviations of dropping point is deduced and the iterative program is designed, an example is given.
