Grease is made of basic grease and additives strictly in a certain proportion of the deployment, the main additives are: anti-wear agents, antioxidants, clean dispersants, etc., it is mainly mainly used in injection molding machines, the following small to tell you grease base grease tips.

First, grease base grease definition

Base grease: that is, the original grease after refining, wax removal, hydrogenation and other processes, the blank grease material, is the main component of grease.

Grease base grease basics

Second, the manufacturing process of grease base grease

The original grease is distilled through the distillation tower to refine the mineral base grease. If on this basis just add solvent for refining, then what you get is I type base grease; if after hydrotreating or deep hydrotreating, you can get II, III base grease. And PAO and other more advanced synthetic base grease, it is necessary to go through a variety of synthetic process before you can get.

Third, the technical index of grease

Viscosity index: the viscosity of grease products with the temperature change degree, with the standard grease viscosity change degree of comparison of the relative value called viscosity index, the higher the number of values, said by the temperature of the impact of the smaller.

Viscosity: When a liquid is moved by an external force, the resistance between its molecules is called viscosity.

Flash point: grease products in the specified conditions, heated to its vapour and the surrounding air to form a mixture of gas, when in contact with the flame issued when the minimum temperature of the flash fire.

Pour point: refers to the cooling for solid grease, tilt placed to warm up to the lowest temperature of the grease began to move.

Fourth, the factors affecting the performance of grease base grease

1, the origin of the original grease: different origins of the original grease, because of the geographical environment, the formation of time, climatic conditions and other differences in the composition of the material composition.

2, the depth of solvent refining: the origin of the original grease quality differences, resulting in the production of the same standard of grease base grease, the need to refine the degree of different.

3, the type of refining process: with or without the depth of hydrotreating, and the depth of hydrotreating the degree of difference, is to distinguish the key indicators of grease base grease API classification.

The above is the sharing of grease base grease tips, if you want to know more information about it, please pay attention to this site.
