惠州惠东长城抗氨汽轮机油-美孚导热油销售导热油（外文名:Heat transfer oil），又称传热油，是GB/T 4016-1983《石油产品名词术语》中"热载体油"的曾用名，属于有机热载体类特种工业油品。该油品通过液相或气相循环实现热量间接传递，具有加热均匀、热稳定性好、低蒸汽压高温操作等特点，广泛应用于橡塑加工、精细化工、化纤生产、能源回收等领域，近年来应用场景持续拓展[1-2]。导热油分为合成型与矿物型两类，其中合成型包含烷基联苯醚型等品种[1]。其性能指标包括热稳定性、氧化安定性及安全性，使用温度最高可达350℃。合成型有机热载体热氧化安定性较差，需在闭式系统中使用。我国执行GB23971-2009标准，要求检测酸值、闪点、残碳等理化指标，系统设计需配套氮气密封、温度监控及泄漏防护装置。开式系统需选用热稳定性和氧化安定性均符合要求的产品，更换新油前需彻底清洗循环传热系统Heat transfer oil, also known as heat transfer oil, is the former name for "heat carrier oil" in GB/T 4016-1983 "Terminology for Petroleum Products". It belongs to the special industrial oil category of organic heat carriers. This oil product achieves indirect heat transfer through liquid-phase or gas-phase circulation, and has the characteristics of uniform heating, good thermal stability, low vapor pressure and high temperature operation. It is widely used in rubber and plastic processing, fine chemicals, chemical fiber production, energy recovery and other fields. In recent years, its application scenarios have continued to expand [1-2]. Thermal oil is divided into two types: synthetic and mineral, with synthetic types including alkyl diphenyl ether types [1]. Its performance indicators include thermal stability, oxidation stability, and safety
