Dimethicones in Lubricating Oils

Dimethicones in Lubricating Oils
Lubricants play a vital role in the industrial and automotive sectors, however, foam is often a problem in lubricants. Foam not only affects lubrication, but can also lead to oil waste and machine wear. In lubricant systems such as electric pumps, the presence of large amounts of foam can cause adverse effects on the normal operation of equipment, such as unstable oil pressure and wear. To solve this problem, scientists have introduced a miraculous substance, dimethyl silicone oil, which has successfully eliminated the nuisance caused by foam by improving the anti-foam properties of lubricants, thus improving the performance and life of the equipment.

01.Anti-foam requirements for electric pump lubricants
During the operation of electric pumps, foam and air bubbles are generated due to air entering the lubricant system. These bubbles can lead to unstable oil pressure and damage the oil film, which in turn affects the operation and life of the equipment. Therefore, lubricants need to have good anti-foaming characteristics.

02.Highly effective antifoam agent dimethyl silicone oil
Dimethicone is a highly effective antifoam agent, its chemical properties and physical effects can improve the anti-foam properties of lubricants. Dimethyl silicone oil has the characteristics of low surface energy and low surface tension, which can effectively inhibit the generation of foam and adsorb on the surface of the foam to make it rupture, reduce the wear of the machine and prolong the service life of the oil.

03.Mechanism of action
Dimethicone is able to reduce foam formation and stability in lubricating oils through its surface-active properties and the role of foam inhibitors. It reduces the surface tension of the foam film so that the foam can be easily ruptured, thus eliminating the large amount of foam generated during the operation of electric pumps.
04. Additional lubrication and protection effects
In addition to the anti-foaming effect, dimethicone oil also has excellent lubricating properties, which can reduce friction and wear between metal parts. In addition, it can form a layer of protective film to prevent the equipment from damage such as oxidation, corrosion and pollution.
Summarize
By adding dimethicone to the electric pump lubricating oil, the anti-foaming characteristics of the lubricating oil can be improved, eliminating a large number of foams generated during the operation of the electric pump, and improving the performance and life of the equipment. The mechanism of dimethicone oil mainly includes the surface active properties and the role of foam inhibitor, which can destabilize the foam, so as to achieve the effect of eliminating foam. In addition, dimethicone oil also has a lubricating and protective effect, further enhancing the use of equipment.
