Discussion on high temperature chain oil Base Oil, additives and formulation technology
With the rapid development of modern industrial technology, the problem of equipment lubrication under extreme conditions such as high temperature, high speed and heavy load has become increasingly prominent. As a special lubricant, the performance of high temperature chain oil directly affects the operating efficiency and life of equipment. This paper will discuss the selection of base oil, additive configuration and formulation technology of high temperature chain oil.
First, the choice of base oil
Base oil is the core component of high temperature chain oil, and its performance directly affects the overall performance of chain oil. When choosing a base oil, consider the following factors:
1. Viscosity grade: Select the appropriate base oil viscosity grade according to the operating temperature, load and speed of the equipment. In general, the base oil with high viscosity index and small viscosity change with temperature should be selected under high temperature conditions.
2. Oxidation stability: high temperature chain oil is prone to oxidation deterioration at high temperatures, so the base oil should have good oxidation stability to ensure the stability of the chain oil at high temperatures.
3. Thermal stability: the base oil should be stable at high temperatures, and it is not easy to decompose and produce precipitate or gas, so as not to affect the lubrication performance of the chain oil.
At present, the commonly used high temperature chain oil base oils include polyether, polyalphaolefin (PAO) and ester oils and other synthetic oils. These synthetic oils have excellent viscosity-temperature properties, oxidation stability and thermal stability, and are suitable for the preparation of high temperature chain oils.
Second, the configuration of additives
On the basis of base oil, the performance of high temperature chain oil can be further improved by adding appropriate additives. Common additives include:
1. Antioxidants: can improve the oxidation stability of chain oil and extend its service life.
2. Extreme pressure anti-wear agent: it can improve the extreme pressure anti-wear performance of the chain oil and reduce the wear of the chain under heavy load and high-speed conditions.
4. Rust inhibitor: can enhance the rust resistance of the chain oil to prevent the chain from rusting in a humid environment.
When configuring additives, it is necessary to select the appropriate type and amount of additives according to the performance of the base oil and the requirements of the use of the chain oil. High temperature chain oil with excellent properties can be prepared by reasonable additive configuration.
3. formula technology
The formulation technology of high temperature chain oil includes the selection of base oil, the configuration of additives and the preparation technology. In the formulation process, it is necessary to comprehensively consider the working conditions of the equipment, lubrication requirements and environmental protection requirements, and formulate a reasonable formula. At the same time, the following points should be noted:
1. Ensure stable and reliable quality of base oil and additives, avoid using inferior raw materials to affect the performance of chain oil.
2. Reasonably adjust the viscosity of base oil and the amount of additives according to the working temperature, load and speed of the equipment.
3. Adopt advanced preparation technology and equipment to ensure stable and reliable quality of chain oil.
In short, the selection of base oil, additive configuration and formulation technology of high temperature chain oil are the key to prepare high performance chain oil. Through reasonable formulation design and preparation process control, high temperature chain oil with excellent properties can be prepared to provide reliable lubrication guarantee for modern industrial equipment.
