With fully synthetic base oil for an oil medium needs to be heated, heat transfer, thermal industrial and civil apparatus. Can be heated to above 250 ℃ synthetic heat transfer oil, safer than mineral oil. HTF heat transfer as a special heat transfer medium, depending on the boiling range, divided into vapor and liquid HTF HTF. The so-called gas-phase heat transfer oil that can be used in high-quality synthetic HTF co boiling point or synthetic heat transfer oil in the gas phase, conducting such a system can be used in a state of stress. And those who have a certain thermal distillation range range of synthetic and mineral-based HTF HTF can only be used under conditions quite liquid phase is called the HTF. HTF this system is very common. The other method of determination of the thermal stability of a thermal oil GB / T 23800 is sealed under nitrogen, heating oil 720h or 1000h, the deterioration rate is calculated to be less than or equal to 10% of the qualified. This nitrogen seal oil furnace system is very good, but for the vast majority of China's oil furnace blanketing systems are no synthetic heat transfer oil processing, are in direct contact with the air system, which is a big problem, under nitrogen sealed performance is good, not necessarily in the non-nitrogen seal performance or. About the extensive use of temperature encountered only 200 ℃, only use 2-3 years to be scrapped, is indicative of the problem.
