HTF our standard-setting process of Fengqiu Taihang Chemical Co., Ltd. attaches great importance to our country HTF formulation of standards, the current standard of HTF behind many other countries than in the West. The early 1980s, our country has undergone a series of changes HTF, the energy industry, along with the introduction of chemical equipment, but also the emergence of a new energy - HTF. Since then, the chemical industry, and some require the supply of heat conducting oil industry are inseparable, and of conducting oil industry has also ushered in a new era. YD320 HTF 1994, our country has developed the first national standard HTF: Lubricants and related products (L class) classification - Part 12: Q group (heat transfer fluid) GB / T 7631.12-94 standard simpler and plainer. But then in 1999, the country once again to develop a new industry standard that SH / T0677-1999. 2009, the new national standard GB 23971-2009 released, on January 1, 2010 to take effect. This can be said to make up our national standard of 30 years of conducting oil industry lacking. 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 YD350 synthetic heat transfer oil, high temperature during use HTF Pay special attention to detail. 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 synthetic HTF HTF YD320, sampling to detect the state of high-temperature heat transfer oil, to keep the HTF quality problems, timely replacement.
