淮安涟水县梁岔镇经销壳牌液压油-导热油导热油的比热、密度与导热油的牌号及使用温度有关，建议按导热油手册或样本上的数据选用。一般情况下，300#导热油在270℃时的比热约为2.7kJ/(kg.K)导热油的型号不同，燃点不同。所有物质的燃点都要高于闪点，导热油的燃点值可以按GB26788石油产品闪点与燃点测定法进行测定。导热油的燃点是指蒸汽与空气形成的混合气体与火焰接触时连续闪火5秒以上的温度。由于导热油的自燃点高于100℃，而且它在空气中的自燃温度高于最高使用温度，所以导热油的渗漏一般不会引发着火事故。但当导热油进入绝热层时，因其表面积增大，其自燃温度可能会降至管道的操作温度以下，如果此时接触氧气有可能着火。在加热炉中导热油泄漏会发生燃烧，并产生浓烟。导热油在130℃以上的温度条件下在空气中会形成爆炸混合物。如果蒸汽压足以形成可燃混合物，爆炸混合物只可能在含有未分解导热油的密封系统中形成。Different types of heat transfer oil, different ignition point. The ignition point of all materials must be higher than flash point. The ignition point value of heat conducting oil can be determined by the method of flash point and ignition point for petroleum products GB26788. The ignition point of heat-conducting oil is the temperature above 5 seconds when the mixture of steam and air contact the flame. Because the self-ignition point of the oil is higher than 100 ° C, and its self-ignition temperature in the air is higher than the maximum operating temperature, the leakage of the oil will not cause the fire accident. However, when the heat transfer oil into the insulation, due to its increased surface area, its spontaneous combustion temperature may fall below the operating temperature of the pipe, if contact with oxygen at this time may catch fire. Heat transfer oil leakage in the furnace will occur combustion, and produce smoke. The heat transfer oil will form explosive mixture in the air at the temperature above 130 °C. If the vapor pressure is sufficient to form a flammable mixture, the explosive mixture may only form in a sealed system containing undecomposed heat-conducting oil.
