HTF manufacturers should inhibit carbon residue generated as a focus of the study, in addition to select high-quality base oils HTF is to study the formula composition, especially the high temperature should be monitored at the same time subject to oxidation, can not have a clear black and oxidation products carbon residue and sediment particles generated as research subjects, rather than think HTF produce acidic substances and soot and sediment is a normal phenomenon, through a period of time before coming to add some additives to solve the problem, in fact, when the additive is something times Gong Wei, not much effect. The other method of determination of the thermal stability of a thermal oil GB / T 23800 is sealed under nitrogen HTF how much a pound, 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 is no HTF wholesale blanketing systems are systems and direct contact with the air, and this is a big HTF problem, sealed under nitrogen perform well, 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.
