Study on the Classification of Oxidizing Solid Packaging by Granulation Treatment

SUN Huaibo;PU Zhengyu;BAI Yun;Shanghai Research Institute of Chemical Industry Co., Ltd./Shanghai TECH.Chemical Industry Testing Co., Ltd.;  
With the widespread use of chemical fertilizers in agricultural production, the state has paid more and more attention to the safe transportation of chemical fertilizers. Some nitrogen fertilizers among which have been judged as 5.1 oxidizing substances due to oxidative reasons, resulting in increased transportation costs. The nitrogen fertilizer sodium nitrate is selected as the research object, and the O.1 oxidizing solid test is performed to analyze the effect of granulation treatment on the classification of oxidizing solid packaging. Test results show that changing physical form of sodium nitrate through the granulation treatment can effectively reduce the oxidization of sodium nitrate in the powder state, and achieve a packaging classification other than 5.1. Therefore, when classifying and judging oxidizing solids, it is recommended to refer to the actual physical state and test data of oxidizing solids to ensure a reasonable determination of oxidizing solids classification.
