Several research studies have been performed to minimise the hygroscopicity of ammonium nitrate for increasing its commercial value and decreasing the nitrogen content. In this study, the hygroscopicity of ammonium nitrate was reduced using silicic acid, calcium lignosulfonate, and sodium silicate in the two-stage vacuum ammonium nitrate production process. Degradation of ammonium nitrate was observed after two years of storage, which is considered a standard by the European Fertilizer Manufacturers Association.
为了降低硝酸铵的吸湿性以提高其商业价值并降低氮含量,已经进行了多项研究。在本研究中,在两段真空硝酸铵生产过程中使用硅酸、木质素磺酸钙和硅酸钠降低了硝酸铵的吸湿性。在储存两年后观察到硝酸铵有降解情况,这是欧洲肥料制造商协会认定的一个标准。
