摘要:
为了获得高温炮孔中防护前后的乳化炸药内部温度变化规律，采用热电偶测温技术对乳化炸药内部不同位置的温度变化曲线进行测量。结果表明：防护下乳化炸药最高温度不超过水浴温度，其内部不同位置的温度变化曲线可通过指数函数进行较好的描述，最外层的温度变化曲线与水的温度变化曲线变化规律基本一致，而内部温度相对较低，说明乳化炸药的外层受到环境温度影响较大，而油包水结构与硝酸铵溶液吸热作用导致内部升温速率相对较慢，因此有利于防护后的乳化炸药在高温火区中得到应用。
Abstract:
In order to obtain the internal temperature distribution of the emulsion explosive in blast hole at high temperatures, the thermocouple temperature measurement technology was applied to measure the inner temperatures (different positions) of the emulsion explosive. The results show that the temperature of the emulsion explosive was lower than that of water and the internal temperaturehistory curve of the emulsion explosive can be better described by an exponential function. The change of temperaturehistory curve of outer emulsion explosive is in accordance with the change of temperaturehistory curve of water, and the inner temperature is relatively lower, which shows the outer of the emulsion explosives are affected by the environmental temperature. The inner temperature rise rate of emulsion explosive is relatively slow because of the waterinoil structure and specific endothermic action of ammonium nitrate. It is advantageous for emulsion explosive under protection to be used in the fire area at high temperatures.
