Why does grease divide oil?

Ingredients of grease: base oil, thickener, additive; The main ingredient is base oil (mineral oil or synthetic oil). The thickener acts like sponge. The thickener is mainly made of fibrous tissue in which the base oil and additives are stored. Just as sponge will be squeezed out of water, the "sponge" of grease will be squeezed out of base oil, and the elements of grease are usually "squeezed" in two ways: mechanical equipment and high temperature.

Is there more thickening agent in the grease, the better?

Obviously, if the thickener is too much, the base oil is firmly sucked up, and the grease of the base oil cannot be released. How to lubricate it? Therefore, the thickening process of grease needs to find the most suitable point.

Grease will precipitate oil in storage and application. A small amount of oil is routine, but too much oil will immediately cause the destruction of grease structure and even the loss of practical value. Proper storage and use skills can control oil separation.

Therefore, grease oil is conventional, such as grease does not have the working ability to release the oil, it is difficult to lubrication, because lubrication depends on the base oil, thickener almost has no lubrication effect.

The percentage of oil in grease is related to the content of thickener. From the composition of grease, it can be seen that the content of thickener in grease is different. Going back to the case of sponge, it is clear that the higher the content of thickener, the less the base oil is difficult to precipitation, and the less the oil.
