Diphenylsilanediol can significantly improve the mechanical stability of greases. During mechanical operation, greases are subject to various shear forces. Diphenylsilanediol can enhance the stability of the grease structure, so that it can still maintain good lubrication performance under high shear force and reduce the performance degradation caused by mechanical stress. For example, in some high-speed mechanical parts, greases with diphenylsilanediol added can effectively resist shear and continue to provide stable lubrication protection for the parts.
It can also improve the colloidal stability of greases. Greases are composed of base oils and thickeners, and the colloidal stability is related to whether the base oil is easy to separate from the thickener. Diphenylsilanediol helps to optimize the internal structure of greases, better combine the base oil with the thickener, prevent the base oil from seeping out, and extend the service life of the grease. This effect is particularly obvious in high temperature environments, which can prevent the grease from failing due to the loss of base oil.
Diphenylsilanediol also has a prominent effect on the improvement of the thermal stability of greases. In high-temperature working conditions, ordinary grease may lose its lubricating effect due to problems such as thermal decomposition. Diphenylsilanediol can enhance the heat resistance of grease, allowing it to maintain stable physical and chemical properties at high temperatures and continue to play a lubricating role. In some high-temperature equipment such as industrial kilns and high-temperature motors, grease containing diphenylsilanediol can ensure long-term stable operation of the equipment in high-temperature environments.
