Development trend of industrial special oil
- 2018-09-29-

The development trend of industrial special oil Since the development of science and technology in the 21st century, the urgent problem to be solved is to save energy and protect the environment. New mechanical equipment is moving toward shrinking volume, reducing weight, increasing power, increasing efficiency, increasing reliability and being environmentally friendly, placing more stringent requirements on industrial-specific oils. The development trend of industrial special oil is to increase the cost of product products and develop environmentally friendly products.

The development of lubricating oil technology mainly comes from two aspects. It is to improve the quality of the base oil through the improvement of the basic oil production technology. It is the key to improve the product through the improvement of the lubricating oil formula technology.

1. Improve production process and improve base oil quality

At present, the development of base oil production is positive hydrogenation technology. The lubricating base oil produced by the hydrogenation technology has low sulfur nitrogen and aromatic content, high viscosity index, good thermal oxidation stability, low volatility and long oil change period. The demand for lubricating oil base oils in the world has gradually increased, and hydrogenation technology has developed rapidly. Polyolefin synthetic oil with high viscosity index and excellent low temperature performance and thermal oxidation stability.

2 , improve the compound formula technology, reduce additives

Most of the modern industrial special oil production uses compound additives for blending, which not only makes the blending process simple, but also reduces the total dosage and saves costs. The compounding technology of additives is a meticulous research work, and it is often necessary to carry out trials of thousands of formulas in order to obtain a satisfactory and reasonable compound formula. Therefore, the generally mature compound formula does not allow the addition of other additives to improve a certain performance, as this will affect other performance indicators. In the compounding technology, in addition to the use of multi-functional additives, it is very important to study the synergistic effect of the additives. The effect of the two additives on the use is much better than when using the additive alone, which can greatly reduce the additives. The total dosage.

Reducing the total dosage of additives in industrial special oils is an important measure to improve oil quality and reduce costs. At present, the total dosage of anti-wear hydraulic oil has dropped from the previous 1.52.0 to 0.40.6 ; the total dosage of industrial gear oil has also dropped below 1.2 . The dosage of some single agents is also significantly reduced. As in the past, a 0.0510 demulsifier was added, and now only 0.005 is added to achieve better results.

3. The application of new technologies in industrial special oils has a better living environment for human beings. In recent years, the requirements and legislation of environmental protection in the world are becoming more and more strict. Industrial-specific oils have become a popular research class in the 21st century due to leakage of equipment and the abandonment of lubricants .

Similarly, due to environmental requirements, it is required to minimize the use of heavy metals in industrial oil formulations, especially to reduce the content of metal zinc in anti-wear hydraulic oils. Therefore, ashless formulations will be the focus of future development.

Another area of ​​application of new technologies in industrial specialty oils is nanotechnology. As we all know, when the equipment is running, it is inevitable that friction will occur and mechanical wear will occur. Shanghai Zhuoli Lubrication Co., Ltd. focuses on the development of lubricants with good wear resistance and high load carrying capacity. It has a certain repair function on the wear surface. The lubricant is less polluting or less polluting. It is an oil-soluble extreme pressure anti-wear additive added to the lubricating oil. In recent years, nanomaterials have developed rapidly, and the application of nanomaterials and technology in the field of lubrication has been highly valued by tribologists.

Research into the use of nanomaterials in lubricating oils to improve their resistance to wear and extreme pressure has become a hot topic. At present, there are two methods for preparing nano-material lubricating oil, namely in-situ synthesis method, which directly synthesizes nano-lubricating materials by using lubricating oil as a medium, and directly disperses in lubricating oil, and the particle diameter is smaller than the wavelength of light, thereby preparing the obtained The lubricating oil is transparent; the second is a two-step process in which an oil-soluble nano-lubricating material is first prepared and then dispersed into an industrial special oil. The amount of nanomaterial in the lubricating oil can be freely modulated as needed. Both of these studies have made a lot of progress, but there is still a gap between large-scale practical applications.
