摘要
为探索微波作用于TNT的安全性和加热熔融TNT方面的潜在应用价值,用改进的商业微波炉在防爆小室对TNT进行了加热试验。研究了微波输出功率、TNT药量、装TNT的容器对温度-时间曲线的影响,采用视频技术摄录了微波加热熔融TNT的全过程,对微波加热前后TNT样品的表面化学和分子结构进行了分析。结果表明,当TNT药量为10,50,100 g、微波炉输出功率为120,240,360 W、装TNT的容器分别为玻璃和塑料时,即使加热时间长达40 m in、最大温升速率达66℃.m in-1、最高温度达146℃,微波加热前后TNT样品的表面化学和分子结构均未发生变化,实验过程未出现燃烧、爆炸现象。
The tests for nnderstanding safety and potential application of melting TNT by microwave heating were carried out in the anti-explosion room by the commercial microwave oven with output power of 0 -600 W,which was improved for safety performances. The effect of output power,loadlng capacity of TNT and container on temperature-time curves were studied. The process for melting TNT were recorded. The surface chemistry and the molecular structure of TNT samples before and after microwave heating were analyzed. The results show that the surface and the structure of TNT do not change after microwave heating when microwave power is 120,240,360 W; loading capacity of TNT is 10,50,100 g; container is of glass or plastic; heating time is 40 min; the maximum heating velocity is 66℃·min^-1; the maximum heating temperature is 146 ℃ ,respectively. Furthermore,combustion or explosion does not occur in the tests.
