Summary
Bubbles in lubricating oil cause oxidation and wear. This study reviews defoaming agents, including silicone, non-silicone, and compound types, to prevent these issues and improve oil performance.
Area of Science:
- Tribology
- Materials Science
- Chemical Engineering
Background:
- Lubricating oil foaming accelerates oxidation, reduces performance, and causes mechanical wear.
- Foaming can lead to critical failures like oil pump interruption and shortage accidents.
Purpose of the Study:
- To comprehensively discuss lubricating oil foaming, its detrimental effects, and mechanisms of defoaming.
- To analyze the synthesis, application, pros, cons, and current status of chemical defoaming agents.
Main Methods:
- Review of foaming processes and their impact on lubricating oils.
- Detailed examination of three primary chemical defoaming agent categories: silicone, non-silicone, and compound.
- Analysis of defoaming mechanisms and methods.
Main Results:
- Silicone, non-silicone, and compound defoaming agents each possess unique advantages and disadvantages.
- Understanding the specific properties of each defoaming agent is crucial for effective application.
- The current landscape of defoaming agents is diverse, with ongoing development.
Conclusions:
- Effective defoaming is essential for maintaining lubricating oil integrity and preventing equipment damage.
- Further research into specialized defoaming agents for lubricating oil applications is warranted.
- The selection and development of defoaming agents directly impact lubricant lifespan and machinery reliability.

Effective lubrication between a rotating shaft and its bearing housing is essential in rotating machinery to minimize friction, wear, and energy loss. With carefully controlled thickness and viscosity, the lubricant layer prevents metal-to-metal contact, ensuring smooth operation.
To calculate the required thickness of the lubricant layer, the tangential velocity at the shaft's surface must first be determined. This velocity is calculated by converting the rotational speed to angular...

Children at play often make suspensions such as mixtures of mud and water, flour and water, or a suspension of solid pigments in water known as tempera paint. These suspensions are heterogeneous mixtures composed of relatively large particles that are visible to the naked eye or can be seen with a magnifying glass. They are cloudy, and the suspended particles settle out after mixing. On the other hand, a solution is a homogeneous mixture in which no settling occurs and in which the dissolved...

Air-entraining agents improve the durability and workability of concrete in climates with frequent freezing and thawing. These agents prevent cracks by introducing small air bubbles into the mix, creating spaces accommodating water expansion when temperatures drop. The air-entraining agents lower the surface tension of water, forming stable, small air bubbles. This method is more effective than having accidental large voids, as the intentional, smaller, and evenly distributed air voids improve...
