TNT渗油性的分析方法及机理

Analysis Method and Mechanism of TNT Exudation

针对TNT渗油性标准及其分析方法,用气相色谱、微量天秤和显微摄影等技术,研究了TNT的渗油机理,通过TNT的注装、压装和螺装模拟实验和不同温度下各种装药的渗油实验,发现该渗油性分析方法不是一种严格精准的测定方法,而且其测定机理与现代各种TNT装药工艺不符。因此,认为现行渗油性标准已经落后,应予取消。建议TNT以凝固点(SP)分级,来适应各种装药的需要。同时建立高分离效能的气相色谱分析方法,从微观上监测TNT中各种杂质的变化,以指导TNT生产和装药工艺,确保弹药质量。

Aiming at the exudation test standard of TNT and its analytical method. The exudation mechanism of TNT is studied by gas chromatograrhy, micro-balance and microphotography. The pour molding, press loading and screw pressing simulated experments of TNT shell charge and the TNT exudation experiment under different temperture of each shell charge are performed. Finding that the TNT exudation test method is not a kind of serious and accurate determination method and its testing mechanism is inconsistent with the present shell charge technologies of TNT, and the present exudation test standard is backword, and shall be cancelled, and suggesting that using the solidifying point as the criteria of classing TNT and high seperation effect gas chromatography to inspect and control the impurities of TNT for directing the production of TNT and the shell charge processing of TNT to ensure the quality of shell charge.
