Users should note the following before buying HTF questions (1) investigate the evaporation products and safety - Flash point (open) standard target, the initial boiling point of not less than its maximum operating temperature, relatively narrow distillation range, lighted compare high. Refined depth (2) examine the product - appearance is light yellow transparent liquid YD350 synthetic heat transfer oil, good storage stability YD320 synthetic heat transfer oil, discoloration or precipitation occurs after exposure. Not more than 0.1% residual carbon, the content of the distillate is not more than 0.2%. Cold flow properties (3) examine the product - according to the ambient temperature region where the user is located and equipment HTF, select the appropriate low temperature performance. QB and QC pour point not more than -9 ℃, low temperature kinematic viscosity (0 ℃ or lower temperature) is relatively low. HTF high temperature process of using heat conducting oil cycle considerations generally longer used in the production process, often encounter a lot of reaction heat conduction system functioning elements YD320 HTF, HTF temperature during use details to special attention. HTF HTF temperature checked regularly in the course of deterioration is inevitable law, deterioration of oil due to oil change ambassador deterioration after each goal easier coke, coking wall once attached to the HTF must be replaced, so , you want to avoid this problem, you must check in the course of regular HTF, sampling to detect the state of high-temperature heat transfer oil, to keep the HTF quality problems, timely replacement.
