Basic Concept of Grease(1) What is grease The latest definition of NLGI (National Lubricating Grease Institute): Grease is a solid or semi-solid product formed by dispersing one or more thickeners into one (or several) liquid lubricating oils . To improve certain properties, some other components (additives or fillers) are added.(2) Thixotropy of grease When an external force is ...

China Petroleum News "The era of easy exploitation of oil and gas has come to an end, and the sustainable development of the oil and gas industry is increasingly dependent on technological innovation. In 2012, the number of first patent applications in the global oil and gas field reached a peak of 25,807, and patent applications with priority in China accounted for 25,807. 54%. China has become the main force of technology research and development in the global oil and gas field.” On September 18, China Petroleum Economic and Technological Research Institute, the largest petroleum economic technology information resource center in China, released the “Foreign Petroleum Technology Development Report (2014)” in Beijing. (hereinafter referred to as the "Report").

The mixing of different greases in the use of grease is unavoidable, but it should be noted that the change in properties after mixing does not affect the use. When the sealed bearing is sealed with high-grade long-life grease at one time, it can prolong the life of the grease and prevent contamination, and avoid the trouble of regular grease, which is the most ideal. However, some bearings...

The commonly used additives for lithium-based grease are similar to other greases, but lithium-based grease uses a wider range of additives, and it has good compatibility with many additives. Commonly used additives mainly include antioxidants, metal surface passivators, preservatives, structural modifiers, extreme pressure antiwear agents, color stabilizers, and wire drawing enhancers. 1. Ant...

When the operating temperature of the bearing increases by 10~15℃, the bearing life of the grease will be reduced by half; select the grease for high temperature and focus on the performance of the dropping point, evaporation, oxidation stability and high temperature baking test of the grease. The selection of low temperature grease should pay attention to the similar viscosity and low temperature torque at low temperature. Effect of temperature on oxidation rate
