Study on Surface Modification of Ammonium Nitrate

Abstract:

This article studied on the surface modification of ammonium nitrate by the liquid coating technology , choosing separately polyvinyl acetate (PVAC), sliced paraffin (Wax),polyethylene glycol (PEG) as coating materials. The samples were characterized by SEM and DSC. The experimental results showed that the modification effects of PVAC and Wax were good. The appearance of modified ammonium nitrate presented spherical, and flowing property was better. Their moisture absorption descended respectively by 30.6%, 23.3% after 24 hours at ambient temperature 30°C and relative humidy 75%.
