In the modern industrial system, there are many seemingly ordinary materials that play a key role. High vacuum diffusion pump oil is one of them. Like an "invisible guardian", it silently supports the precision manufacturing and scientific research work related to high vacuum environments. From everyday light bulbs and monitors to cutting-edge electron microscopes and atomic accelerators, it is indispensable for their help.



From the outside, high vacuum diffusion pump oil is a colorless, transparent, oily liquid. This pure form is no accident, but rather an external manifestation of its inherent properties. One of its most core characteristics is its extremely low saturated vapor pressure. During the operation of high vacuum equipment, the number of gas molecules in the environment needs to be controlled at an extremely low level. Low saturated vapor pressure means that the oil itself evaporates very little at operating temperature, effectively preventing the generation of additional gas molecules due to oil vapor, thereby ensuring the stability of the vacuum level within the equipment and providing a reliable environmental foundation for precision processes.

Excellent thermal stability is another major advantage of high vacuum diffusion pump oil. When high vacuum equipment is operating, the pump body often generates a certain amount of heat due to mechanical operation and energy conversion, and in some application scenarios, the internal temperature of the equipment can even rise significantly. At this time, the strong thermal stability of the pump oil allows it to maintain a stable physical state and chemical properties over a wide temperature range, and will not decompose or deteriorate due to temperature changes, thereby maintaining the continuous and efficient operation of the equipment and reducing downtime and maintenance costs caused by oil failure.

At the same time, good antioxidant properties also provide a guarantee for the long-term use of high vacuum diffusion pump oil. In industrial environments, equipment is inevitably exposed to a small amount of oxygen during operation. If the oil has insufficient antioxidant capacity, it will easily react with oxygen to form oxides, which will not only affect the performance of the oil itself, but may also cause impurities to adhere to the inside of the equipment, affecting the equipment's accuracy and service life. High vacuum diffusion pump oil, with its excellent antioxidant properties, can effectively delay the oxidation process, extend its service life, and reduce the frequency of equipment maintenance.

Thanks to these excellent properties, high vacuum diffusion pump oil has a wide range of applications. In the high vacuum smelting industry, it provides a clean high vacuum environment for the purification of metal materials and the preparation of special alloys, helping to improve the purity and performance of metal materials. In the electron tube industry and light bulb manufacturing, it ensures the normal operation of electronic components and filaments in a vacuum state, reduces gas interference with component performance, and extends product life. In high vacuum coating (film) processes, a stable vacuum environment is key to ensuring uniform coating and strong adhesion, and high vacuum diffusion pump oil is a vital support for this process.

In more cutting-edge scientific research and manufacturing fields, such as atomic accelerators and electron microscopes, the requirements for vacuum levels are even more stringent. The low saturated vapor pressure, strong thermal stability, and antioxidant properties of high-vacuum diffusion pump oil are fully utilized, providing stable and reliable guarantees for cutting-edge work such as particle acceleration experiments and microscopic observations. In the display production process, it also participates in the high-vacuum link of panel manufacturing, helping to produce display products with clear image quality and stable performance.
