| Abstract: | To decrease surface polarity and hygroscopy of ammonium nitrate (AN),a surfactant,a coupling agent and a polymer were used to coat AN particles. Spraying-drying technique was used in coating technology. The surface polarity,surface structure and hygroscopic rate of the coated AN particles were studied by surface energy measurement,scanning electron microscopy and moisture experiment. It was obtained that the coated AN particles by surfactant,coupling agent and polymer showed low surface polarity and hygroscopic rate. |
