HTF reason to be scrapped, simply because: 1. From the analysis of the physical and chemical indicators, excessive carbon residue value added, heat oil parameters, acid value exceeding excessive viscosity, flash point change is too large; 2 from the performance point of view. heat transfer effect of variation, increased energy consumption, heating time becomes longer, clogging occurs locally; 3. HTF appearance scrapped or thickens, the color black or oil of a precipitate. In short, the different formulation system and different HTF base oil will have different manifestations. HTF manufacturers should suppress carbon residue generated as a focus of the study, in addition to select high-quality base oils, it is to study the formula composition, Xiamen heat transfer oil, particularly the high temperature should be monitored at the same time subject to oxidation, heat oil use, obviously can not have a black oxidation products and residual carbon particles and sediment generated as research subjects, rather than think HTF produce acids and soot and sediment is normal, heat oil selection, supplemented by a period of time before some Additive again to solve the problem, in fact, when the additive is reactive with twice micro, not much effect.
