舟山定海区普陀美孚液压油-导热油供应链d高温导热油是一种以芳烃为主要成分（含量≥99%）的特种传热介质，也称传热油或热载体油[2]。其通过低蒸汽压实现高温传热，合成型高温导热油可满足最高温度350℃以下的导热需求[5]，具备控温稳定、加热均匀及热效率较高等特点，广泛应用于化工、石油、纺织、食品等工业领域[2]。我国相关标准包括SH/T 0677-1999及GB 23971-2025。依据GB 30000.7-2013，其设计闪点通常不低于180℃，在《安全技术说明书》(SDS)中通常被分类为“可燃液体”。但当其在高温（如300℃）运行时，操作温度已超过其闪点，需按乙B类可燃液体进行防火设计，泄漏后存在火灾爆炸风险High-temperature thermal oil is a special heat transfer medium primarily composed of aromatic hydrocarbons (with a content of ≥99%), also known as heat transfer oil or thermal carrier oil [2]. It achieves high-temperature heat transfer through low vapor pressure. Synthetic high-temperature thermal oil can meet heat transfer requirements up to a maximum temperature of 350°C [5], featuring stable temperature control, uniform heating, and high thermal efficiency, making it widely applicable in industries such as chemicals, petroleum, textiles, and food [2]. Relevant standards in China include SH/T 0677-1999 and GB 23971-2025. According to GB 30000.7-2013, its designed flash point is generally no lower than 180°C, and it is typically classified as "flammable liquid" in the Safety Data Sheet (SDS). However, when operating at high temperatures (e.g., 300°C), the operating temperature exceeds its flash point, requiring fire protection design for Class B flammable liquids, with potential fire and explosion risks in case of leakage
