Problems solved by technology

[0007] Heat transfer oil is mostly used under continuous high temperature conditions, and its operating temperature is generally between 200-400 ° C. If heat transfer oil is operated in a high temperature environment for a long time, thermal cracking, polycondensation and oxidation reactions will occur. As a result of thermal cracking reactions, low boiling point substances will be produced. , leading to lower flash point and lower safety
Low boiling point substances will also undergo polymerization and condensation to form high molecular substances, colloids, etc., resulting in increased viscosity and carbon residue, causing coking, which adheres to the tube wall of the heating furnace, reducing heat transfer efficiency and increasing energy consumption
The oxidation reaction produces organic acid, which increases the acid value of the heat transfer oil. Deep oxidation also produces insoluble acid mud, which increases the viscosity of the heat transfer oil, which eventually shortens the service life of the heat transfer oil and even damages the equipment. Therefore, the heating rate and Service life is especially important

Abstract

The invention relates to heat transfer oil and concretely relates to a preparation technology and a usage method for high-conductivity heat transfer oil. According to the preparation method for the high-conductivity heat transfer oil, the high-conductivity heat transfer oil comprises base oil and additives, and the additives comprise an anti-oxidant, a cleaning dispersant, a viscosity-reducing agent and a metal deactivator. The heat transfer oil has relatively high flash point and boiling point, so that the stability and the safe usage of the heat transfer oil in a liquid phase state are guaranteed. At an allowed highest usage temperature, the heat transfer oil is fast in temperature raising speed, energy-saving and environment-friendly, the temperature raising speed of the disclosed heat transfer oil is faster than that of a same-kind product by 10 DEG C or more, and the service life of the heat transfer oil is prolonged by 3-5 years.
