Measurement and Adjusting Technology for the Related Parameters of Ammonium Nitrate Solution Used in Industrial Explosives

文章对硝酸铵溶液在工业炸药应用中的测定技术进行了分析,研发了硝酸铵溶液质量分数和p H的实验室测定技术及在线测定和调节技术,并进行了对比分析。结果表明,采用温度-密度-质量分数对照表法测定硝酸铵溶液的质量分数,其速度快;10%体积分数的硝酸铵溶液p H测定法更为简单快捷,结果与HG/T 4523—2013中硝酸铵溶液测定法的结果吻合性较好。硝酸铵溶液质量分数、p H的在线测定与调节技术能够满足工业炸药连续化和自动化生产的要求。

Measurement technology of the ammonium nitrate solution applied in industrial explosives was analyzed,and the laboratory determination technology,online determination and adjusting technology of the mass fraction and p H value of the ammonium nitrate solution were developed in comparison. Results show that temperature-density-mass fraction table method is fast to measure the mass fraction of ammonium nitrate solution,while the determination method of p H value,with method of 10 percent volumetric of the ammonium nitrate solution,is more simple and quick,the test results of which are consistent with method of HG / T 4523—2013 for determination of the ammonium nitrate solution. The online determination and adjusting technology of the mass fraction and p H value of ammonium nitrate solution enables to satisfy the requirement of continuous and automatic production quality of the industrial explosives.
