In the preparation and use of high-temperature synthetic heat transfer oil, there are several substances that need special attention and avoidance of use, which may have adverse effects on the performance of the heat transfer oil and even cause safety issues. The following are some main substances that cannot be used for high-temperature synthetic heat transfer oil:

1. Water: Water easily evaporates at high temperatures, forming bubbles that affect the heat transfer efficiency and stability of thermal oil. At the same time, water can accelerate the oxidation and corrosion of thermal oil, shortening its service life.

2. Corrosive substances such as acid and alkali: These substances will react with the chemical components in the heat transfer oil, causing it to deteriorate and reduce its performance.

3. Oxidizing substances: such as certain unsaturated hydrocarbons, they are prone to react with oxygen at high temperatures, causing the thermal oil to oxidize and deteriorate, resulting in precipitation and gum formation, which affects the heat transfer efficiency.

4. Heavy metals and their compounds: These substances may catalyze the oxidation reaction of heat transfer oil, accelerating the deterioration process of heat transfer oil.

5. Solid particles and impurities: They can clog the pipelines and filters of the heat transfer oil system, affecting the flow and heat transfer efficiency of the heat transfer oil.

Therefore, in the preparation and use of high-temperature synthetic thermal oil, the quality of raw materials should be strictly controlled to avoid the mixing of the above-mentioned substances. At the same time, regular maintenance and inspection of the heat transfer oil system should be carried out, and the heat transfer oil should be cleaned and replaced in a timely manner to ensure its normal operation and safety.

In addition, it should be noted that different types of high-temperature synthetic heat transfer oils have different characteristics and applicable ranges. When selecting and using, it should be based on specific application requirements and system conditions, and follow relevant safety operating norms and guidelines.
