Core processes in display manufacturing, such as vacuum coating and cathode ray tube processing, place stringent demands on the cleanliness and stability of the vacuum system. The excellent antioxidant properties of diffusion pump oil play a crucial role in this process. During production, when equipment starts up or stops, or when accidentally exposed to the atmosphere, the high-temperature pump oil is easily exposed to oxygen. Oils with poor antioxidant properties will quickly deteriorate, forming sludge.
These impurities contaminate the vacuum chamber and coating target, leading to coating defects and uneven color in the display panel, directly impacting product yield. Diffusion pump oil with excellent antioxidant properties effectively inhibits high-temperature oxidation reactions, reduces sludge and carbon buildup, keeps the pump body clean, and ensures the continuous and efficient operation of the pumping system.
A stable vacuum environment not only allows for a more uniform and dense coating layer on the display but also extends the maintenance cycle of production equipment and reduces manufacturing costs. In the vacuum packaging process of precision electronic components, the clean vacuum provided by antioxidant pump oil further ensures the long-term stability of the display, helping high-end display technologies achieve higher image quality.
