What additives do lubricants have?

Date of release:2019-07-31 Author:Venezuel Click:

    

The main components of Zhongshan lubricating oil are base oil and various additives. Moisture in lubricating oil can promote oxidative deterioration of base oil to produce emulsification. The additives in lubricating oil are generally organic compounds. The detergents, dispersants, antiwear agents and preservatives are all surfactants. They are easy to form micelle state, which results in the failure of additives.

Analysis with modern instruments. If the change of additives in oil is determined by infrared spectroscopy, the change of metal abrasives or elements in oil is determined by ferrography or ICP emission spectroscopy. Instrument analysis is fast and accurate, which is of great significance to the lubrication management of large-scale key equipment such as generating units. At the same time, it is also a method to improve the effect of lubricating oil.

Put the lubricating oil to be checked in a cup, then put an empty sheet on the table, lift the quilt containing lubricating oil, let the lubricating oil flow slowly into the empty cup, and observe its flow. The lubricating oil flow with good quality should be slender, uniform and continuous. If the oil flow occurs suddenly and slowly, sometimes a large amount of it flows down. It says that the lubricant has deteriorated.

Twist Zhongshan lubricating oil between thumb and index finger and grind repeatedly. Better lubricating oil hands feel lubricity, less debris and no friction. If the friction between fingers is larger, the lubricating oil has deteriorated and can not be used any more, so the lubricating oil should be replaced immediately. Lubricating oil is a kind of liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. It mainly plays the roles of lubrication, auxiliary cooling, rust prevention, cleaning, sealing and buffering (Roab). As long as it is applied between two relatively moving objects, it can reduce the function of friction and wear caused by contact between two objects, that is, lubricating oil.

    Lubricating oil manufacturers point out that lubricating oil generally consists of base oil and additives. Base oil is the main component of lubricating oil, which determines the basic properties of lubricating oil. Additives can make up for and improve the deficiencies in the performance of base oil, and give some new properties, which is an important part of lubricating oil. Promote sludge formation. Moisture can also react with impurities in lubricating oil, such as iron chips, to form iron soap, and iron soap reacts with larger particles in oil, such as colloid, to form sludge. These sludges accumulate in the oil pipeline system, resulting in insufficient oil supply on the friction surface, accelerating the wear of the machine parts and reducing the service life of the machine.
