The principle of operation of lubricants

Everyone knows that machines require lubrication with a certain amount of oil during operation, yet few people truly understand why lubricants are necessary. So let’s take a look at the underlying principles behind how lubricants work. Lubricating oil consists of a base oil and specialized additives. When the lubricant comes into contact with moving surfaces, it forms a physical adsorption layer; the finer the oil, the stronger this adsorption becomes, causing polar molecules from the additives to accumulate on the metal surface. During operation, several scenarios may arise: a) Instantaneous high temperatures at the contact interface; b) Elastic–plastic deformation of microscopic surface asperities, leading to the emission of high‑energy electrons that impact the surface; c) Self‑catalytic repair of the metal surface. These factors can trigger complex, rapid chemical reactions on the frictional surfaces, quickly forming a chemically adsorbed protective film composed of substances that provide anti‑wear, friction‑reducing, and extreme‑pressure resistance properties. Meanwhile, the base oil absorbs and contains undesirable byproducts and excess energy generated during friction, while also promptly supplying the necessary additives or polar molecules. Thus, additives play a crucial role in anti‑wear, friction reduction, equipment protection, and energy conservation. In essence, the combination of base oil and additives delivers optimal performance: providing lubrication for machinery while, to a certain extent, safeguarding its operation. For these reasons, lubricating oil is indispensable for modern machines.

What is a lubricant defoamer? Let’s get to know it together.

Most industrial machinery requires lubricating oil during operation to reduce friction between components, thereby extending equipment life and providing functions such as cushioning, lubrication, rust prevention, and water resistance. However, under the intense agitation and vibration of machinery, lubricating oil can generate substantial foam, and if the foam has excessive viscosity, it becomes difficult to dissipate naturally. This not only damages mechanical equipment but also reduces operational efficiency. Consequently, defoamers for lubricating oils have been specifically developed to address this issue. Let’s take a closer look at them. Lubricating oils often exhibit high viscosity, and when subjected to rapid gear rotation and vigorous agitation, they readily form foam. Additionally, some manufacturers add large quantities of chemical additives to enhance oil performance; these surfactants are particularly prone to foaming. Furthermore, as the oil flows and comes into contact with air during operation, foam may arise. Such foam can clog oil passages, disrupt lubrication, damage machine parts, and lead to even more serious losses. Therefore, timely elimination and control of foam are crucial, making lubricating‑oil defoamers indispensable. The defoaming mechanism of lubricating‑oil defoamers: These defoamers consist of substances with high surface activity. Their strong surface tension enables rapid adsorption onto the oil film, replacing or modifying the existing foam layer to form a new surface film while simultaneously reducing the surface tension of the foaming liquid, thus causing the foam to collapse. They exhibit excellent compatibility with lubricating oils, without compromising product quality or performance. Moreover, they maintain stable defoaming and antifoaming effects across a broad pH range and temperature spectrum, and demonstrate good resistance to high pressure and shear forces. With minimal dosage, they deliver outstanding defoaming results, helping to reduce costs. Due to their low solubility, these defoamers offer superior diffusion and penetration, allowing the active ingredients to disperse throughout the foaming liquid at a rate of approximately 0.8 square meters per second. They are compatible with oils and glycols, effectively eliminating both large and fine bubbles. Applications of lubricating‑oil defoamers: They can be used in metalworking lubricants, anti‑rust oils, various cutting oils, hydraulic fluids, heat‑treatment media, soldering fluxes, forming oils, drawing oils, die‑casting oils, stamping oils, EDM oils, water‑glycol hydraulic fluids, coolants, grinding (oil) fluids, wire‑cutting fluids, dehydrating agents, and other types of oils, including saponified oils. Instructions for use: Before application, thoroughly stir the product. Apply directly by pouring or using a dropper method. If separation occurs, simply remix before use—this will not affect performance. The recommended dosage is 0.1–0.3%, which can be adjusted according to specific conditions. Prior to use, customers should carefully read the product instructions, understand its applicable scope, and conduct small‑scale trials to ensure proper application.

How to quickly identify fully synthetic lubricants

Synthetic oil is produced through chemical synthesis or refining processes, which are complex and costly. It offers advantages that mineral oil cannot match. Synthetic oil was first developed by the Germans during World War II and gained widespread use in the 20th century. In developed countries in Europe and North America, most cars now use fully synthetic motor oil, with oil-change intervals extending up to three years. This type of oil demonstrates exceptional superiority in engine protection, energy efficiency, and environmental sustainability. Synthetic oil is derived from ethylene and propylene—components separated from natural gas or associated gas—and undergoes intricate chemical reactions such as polymerization and catalysis (e.g., Fischer–Tropsch synthesis, also known as GTL technology) to produce high‑molecular‑weight base oils. Essentially, it utilizes the higher‑quality fractions of crude oil, chemically modified and precisely engineered to achieve desired molecular structures. Its molecules are neatly arranged, giving it strong resistance to external variables. Consequently, synthetic oil exhibits superior quality, with markedly better thermal stability, oxidation resistance, and viscosity retention compared to mineral oil. The base oils used in fully synthetic lubricants—polyalphaolefins (PAOs) or esters—are compatible with mineral oils, making it difficult for the average consumer to distinguish them visually. The primary method of identification today relies on price, since the production costs of synthetic base oils are significantly higher, resulting in retail prices typically exceeding those of mineral oils. Many brands on the market claim their products are fully synthetic PAO or ester‑based, but most of these claims rely on vague concepts or ambiguous descriptions—such as “synthetic technology,” “suspension technology,” or “nanotechnology.” Such vague assertions do not constitute genuine fully synthetic motor oil. As modern vehicle technology continues to advance, engine lubricants have likewise evolved, fully embracing the synthetic era. While synthetic oils are more expensive, their higher cost is justified by their unique performance characteristics, enabling them to meet demands that conventional mineral oils simply cannot fulfill. Low-Temperature Fluidity: After a vehicle has been idling overnight—especially in winter—the lubricant’s temperature drops sharply, causing its viscosity to increase. Upon restarting the engine, the oil must flow quickly to minimize wear on moving parts. High-Temperature Stability: Elevated engine temperatures accelerate oil oxidation, leading to performance degradation and increased wear. High-temperature stability measures an oil’s ability to resist oxidation and shear forces under extreme conditions. Anti-Wear Performance: Within the engine, relatively moving components experience continuous friction during high-speed operation. Synthetic oil must maintain a protective film between these parts to prevent excessive wear. Cleanliness: As the lubricant circulates within the engine, it should effectively clean carbon deposits and disperse sludge.
