The nature and use
of lubricants in the field of chemical production raw materials
1. Introduction

lubricants play an important role in the field of chemical production raw materials, they can reduce friction, reduce wear, improve the operating efficiency and service life of equipment. This article will introduce the nature and use of lubricants in detail, so that readers can better understand and apply lubricants.

2. the nature of the lubricant

1. viscosity

viscosity is one of the most important properties of the lubricant, it represents the size of the lubricant fluidity. The greater the viscosity, the worse the fluidity and the better the lubrication effect. Therefore, when selecting a lubricant, it is necessary to select the appropriate viscosity according to the working conditions and requirements of the equipment.

2. Polarity
The polarity of the
lubricant also has a great influence on its lubrication effect. Non-polar lubricants are mainly used for metal processing and mechanical lubrication, while polar lubricants can be used for lubrication under high temperature, high pressure and high humidity conditions.

3. Stability

lubricants need to have good thermal and oxidative stability to ensure that they can maintain their performance and life under high temperature and high load conditions.

4. Compatibility

lubricants need to have good compatibility with the materials and equipment being lubricated to avoid adverse effects such as corrosion and chemical reactions.

3. the use of lubricants

1. Reduce friction and wear
The most basic use of
lubricants is to reduce friction and wear. During the operation of mechanical equipment, the lubricant can form a film to separate the two friction surfaces, reducing direct contact and friction, thereby reducing wear and energy loss.

2. Cooling and cooling

some high-speed equipment, such as machine tools, drilling rigs, etc., will generate a lot of heat during operation. Lubricant can take away part of the heat, play the role of cooling and cooling, to maintain the normal operation of the equipment.

3. Prevent corrosion and rust

lubricants also have the effect of preventing corrosion and rust on the metal surface. Some lubricants containing anti-rust additives can form a protective film on the metal surface to isolate air and moisture and prevent metal corrosion and rust.

4. Cleaning and flushing

Some lubricants also have the function of cleaning and flushing, which can remove oil and impurities on the surface of the equipment and keep the equipment clean and running normally.

4. Lubricant Classification

1. Mineral oil lubricant

Mineral oil lubricant is a lubricating oil extracted from petroleum. It has good lubricating performance and stability and is suitable for most mechanical equipment.

2. Synthetic lubricant

Synthetic lubricant is a lubricating oil made by chemical synthesis method, which has higher viscosity index, better oxidation resistance and thermal stability, and is suitable for lubrication under high temperature, high load and high humidity conditions.

3. Animal grease lubricant

Animal grease lubricant is mainly a lubricating oil extracted from animal fat, which has good adhesion and lubricity, and is suitable for lubrication under some low speed, heavy load and high temperature conditions.

4. Vegetable grease lubricant

Vegetable grease lubricant is mainly a lubricating oil extracted from plant seeds, which has good oxidation resistance and adhesion, and is suitable for some metal processing and mechanical lubrication.

5. conclusion

lubricants play an important role in the field of chemical production raw materials, which can reduce friction and wear and improve the operating efficiency and service life of equipment. When selecting lubricants, it is necessary to select appropriate lubricants and lubrication methods according to the working conditions and requirements of the equipment to ensure the normal operation and production efficiency of the equipment.
