HTF reason to be scrapped, simply because: 1. From the physical and chemical indicators analysis, high-temperature synthetic heat transfer oil, carbon residue value added exceeded, synthetic heat transfer oil, acid value exceeding professional synthetic heat transfer oil, excessive viscosity, flash point change too large; 2 from the use of performance point of view, the effect of variation of heat transfer, increasing energy consumption, heating time becomes longer, clogging occurs locally; 3. scrapped HTF appearance or thickening, color black or oil There precipitate. In short, the different formulation system and different HTF base oil will have different manifestations. HTF is composed of base oil and additives. One view is that selecting the appropriate base oil, plus additives, quality generally not be a problem, Jilin synthetic heat transfer oil, but our view is not exactly correct, and even very different. On the same kind of base oil, since different additive combinations, have a totally different quality performance. We were used to group II base oil hydrogenation and seven major domestic production of conducting oil compound additive products can be complex, respectively 7 Hydrogenation HTF products. HTF quality of the final decision is formula, which does not explain the basis of oil is not important to choose the depth of refined base oils with completely by the above test method formulation technology to produce world-class products HTF.
