干粉灭火剂中磷酸二氢铵含量检测的影响因素

摘要

In order to ensure more accurate detection of ammonium phosphate in dry fire extinguishing powders,through a large number of experiments,the influencing factors on the content test results of ammonium dehydrogenate phosphate in fire extinguishing powders and control measures were discussed.The effects of different experimental conditions and operation method on the test results were focused on.The results show that adding amount of acetone as 2 mL,the sample is dissolved in water at 70 ℃,adding precipitant at boiling state,C6H18O24P6concentration reaches 40 mL,the test results not only can guarantee the accuracy of data,but also satisfy the standard requirements.%为了能更准确地检测干粉灭火剂中磷酸二氢铵组分含量,根据工作经验,对磷酸二氢铵检验结果的影响因素及控制措施进行探讨,重点讨论不同试验条件及操作方法对磷酸二氢铵检验结果的影响.结果表明,丙酮加入量为2mL,溶解试样水温在70℃左右,微沸时加入沉淀剂,喹钼柠酮用量达到40mL时,检测结果既能保证磷酸二氢铵组分检测数据的准确性,又符合国家标准的要求.
