Read： 516 Time：12months ago Source：Transform the World with Simplicity

Lubricating oil is a widely used chemical raw material, which is mainly used to reduce the friction and wear between mechanical parts and improve the operating efficiency and service life of equipment. The nature and use of lubricating oil is very extensive, the following will be described in detail.

1. the nature of lubricating oil

1. viscosity
viscosity is one of the most important properties of lubricating oil, it represents the size of the lubricating oil fluidity. The higher the viscosity, the worse the fluidity, but the better the lubrication performance, so choosing the appropriate viscosity is the key to ensure the normal operation of the equipment.

2. Extreme pressure
The extreme pressure of lubricating oil refers to the ability to maintain proper lubrication performance under high temperature and high pressure conditions to prevent seizure and seizure between mechanical parts.

3.
oxidation resistance Lubricating oil will be affected by high temperature, oxygen and other factors during use, and it is prone to oxidation and deterioration. Therefore, the oxidation resistance of lubricating oil is very important to ensure the long-term use of oil.

4. anti-corrosion
lubricating oil should have anti-corrosion, prevent mechanical parts from corrosion and rust.

2. The use of lubricating oil

1. Anti-friction and anti-wear
lubricating oil forms an oil film between mechanical parts to reduce friction and wear, and reduce the damage and maintenance costs of mechanical parts.

2. Cooling and cooling
Lubricating oil can absorb the heat generated by mechanical movement, reduce the temperature of the equipment, and maintain the normal operation of the equipment.

3. Sealing and anti-leakage
The oil film formed by the lubricating oil between the mechanical parts has a certain sealing performance and can prevent gas or liquid leakage.

4. Anti-corrosion protection
lubricating oil can protect mechanical parts from corrosion and rust and prolong the service life of equipment.

5. Cleaning and flushing
lubricating oil can flush impurities and contaminants on the surface of mechanical parts and keep the equipment clean. The application of

3. lubricants in the production of chemical products

lubricants are widely used in the production of chemical products, mainly for the lubrication and protection of various mechanical equipment. For example, lubricating oil can be used for the lubrication of chemical reactors, agitators, pumps, compressors and other equipment to improve the operating efficiency and service life of the equipment. At the same time, in the production process of some chemicals, lubricating oil can also be used as raw materials to participate in the reaction, improve the quality and yield of products.
Precautions for storage and use of
4. lubricants

1. Precautions for storage
lubricants should be stored in a dry, cool, and ventilated place, avoiding direct sunlight and high temperatures. At the same time, different types and specifications of lubricating oil should be stored separately to avoid confusion and pollution.

2. Precautions for use
When using lubricating oil, the appropriate lubricating oil variety and viscosity should be selected according to the requirements of the equipment, and the lubricating oil should be checked and replaced regularly to maintain the normal operation of the equipment. At the same time, attention should be paid to the cleanliness and hygiene of the lubricating oil to avoid the entry of impurities and pollutants.

In short, lubricating oil plays an important role and is widely used in the field of chemical production raw materials, and is of great significance for ensuring the normal operation of equipment and improving production efficiency. During use, attention should be paid to selecting the appropriate variety and viscosity, regularly check and replace the lubricating oil, and maintain the normal operation of the equipment.
