What are the reasons for the low flash point of heat transfer oil?

There are many reasons for the low flash point of heat transfer oil; the main ones are as follows: 1. Oxidation: Under high-temperature conditions, heat transfer oil is prone to oxidation reactions, resulting in the formation of substances with high boiling points. These substances can lower the flash point of the heat transfer oil. 2. Contamination: During transportation, storage, and use, heat transfer oil is prone to contamination by external impurities, moisture, and other oils, which can lead to a decrease in its flash point. 3. Insufficient hydrogenation: During the production process of heat transfer oil, insufficient hydrogenation or poor hydrogenation conditions can also lead to a decrease in its flash point. 4. Overheating: If the heat transfer oil is overheated during use, it can also lead to a decrease in its flash point. The main methods for addressing the low flash point of heat transfer oils are as follows: 1. Choose high-quality heat transfer oils and avoid using low-quality ones. 2. Strictly control the heating temperature and operating conditions of the heat transfer oil; try to avoid overheating as much as possible. 3. Regularly monitor the quality of the heat transfer oil, and promptly clean and replace any contaminated heat transfer oil. 4. Strengthen the maintenance and management of heat transfer oil, and take effective measures to prevent it from being affected by external contamination, etc. .
