机械安定性

利用滚筒试验机考察了不同含量ZDDP对锂-钙基润滑脂抗水性和机械安定性的影响。

The influence of different zinc dialkyl-dithiophates ( ZDDP ) content on anti-water and mechanical stability of Lithium-Calcium base grease were studied by the roll stability tester .

研究发现，ZDDP能提高锂-钙基润滑脂的抗水性；低含量ZDDP能提高锂-钙基润滑脂的机械安定性；

It was found that ZDDP can improve the anti-water performance of Lithium-Calcium base grease and the performance of mechanical stability with the low content of ZDDP in the grease .

具有良好的抗水性、防锈性、机械安定性、胶体安定性、防腐蚀性和氧化安定性。

It has good water preventive function , antirust performance , mechanical stability , colloid stability , anticorrosion performance and oxide stability .

应用这一概念，可以解释润滑脂的胶体安定性、机械安定性和润滑性。

The colloidal stability , the mechanical stability and the lubricity of lubricating grease can be explained by means of this concept .

通过对研磨前后润滑脂热安定性、机械安定性、胶体安定性等性能的比较，筛选出性能最优的研磨处理工艺。

The thermal stability , mechanical stability and colloidal stability of lithium complex grease were compared . The optimal process was screened out . 4 .
