Grease lubricant No. 1, No. 2, No. 3 means its viscosity.

Introduction of grease:

(1) It is a semi-solid lubricant for mechanical parts made by adding thickener and lubricating additives to the base oil.

(2) grease is commonly known as butter, butter.

Basic composition:

(1) grease is mainly composed of thickener, base oil, additives, three parts.

(2) The content of thickener in general grease is about 10%-20%, the content of base oil is about 75%-90%, and the content of additives and fillers is below 5%.

The consistency grade: No.l, No.2, No.3.

For example, the classification code of general lithium grease is: L-XBCHA1, 2, 3.

Classification principle:

(1)GB501-65 is classified according to thickening agent and grouped with the first letter of the alphabet of the pinyin alphabet of the soap-based grease as a symbol.

(2) GB7631.S I 90 is classified according to the operating conditions when the grease is applied.

Features:

(1) Compared with lubricating oils with comparable viscosity, grease has higher load-bearing capacity and better damping and vibration-damping ability.

(2) Due to the absorption effect of the thickener structure system, the grease has a lower evaporation rate. Therefore, in the lack of grease lubrication state, especially in high temperature and long cycle operation, grease has better characteristics.

(3) Due to the capillary effect of the thickener structure, the base oil of the grease has less tendency to creep compared to lubricants of comparable viscosity.
