非爆炸且不可还原农用硝酸铵的改性研究与测试技术

Based on a study of the relationship of ammonium nitrate （AN） explosion and its thermal stability, inert agents were added to AN for eliminating the explosive characteristic of AN and in order to be irrestorable. The results of using a large quantity of experiments and various testing technologies show that the improvement on thermal stability of modified AN is the basic reason for eliminating explosive characteristic of AN. The modification scheme was considered to have the following features： reliable and stable technology, market-demanded product, low investment and good economic returns. And during the revamping period, the normal production of AN will not be af- fected, and the economic, social and environmental benefits are good.

And during the revamping period, the normal production of AN will not be affected, and the economic, social and environmental benefits are good.
