What Is a Surgical Lubricant?

Lubricant is a lubricating medium used to reduce the friction resistance of friction pairs and slow their wear. Lubricants can also cool, clean, and prevent contamination of friction pairs. To improve the lubricating properties, suitable additives can be added to certain lubricants. When selecting a lubricant, many factors such as the motion of the friction pair, material, surface roughness, working environment and conditions, and the performance of the lubricant must be considered. In machinery and equipment, lubricants are mostly distributed to the parts that need lubrication through a lubrication system.

Industrial lubricants

The main role is to reduce friction damage to friction surfaces. But by

Lubricant viscosity

The viscosity of a lubricant is qualitatively defined as its flow resistance, which is one of the most important properties of a lubricant.

Lubricant oily

Oiliness refers to the adsorption of polar molecules in the lubricating oil on the metal surface to form a boundary oil film to reduce friction and wear performance. The better the oiliness, the stronger the oil film and metal surface adsorption capacity.

Extreme pressure of lubricant

Extreme pressure performance is the performance of the polar molecules in the oil to form a wear-resistant, high-pressure resistant chemical reaction boundary film on the metal surface after the organic polar compounds of sulfur, chlorine and phosphorus are added to the lubricating oil.

Lubricant flash point

When the oil heats the evaporated oil and gas in a standard instrument, the minimum temperature at which it can emit a flash when it encounters a flame becomes the flash point of the oil.
