Experimental investigation of the inerting effect of crystalline II type Ammonium Polyphosphate on explosion characteristics of micron-size Acrylates Copolymer dust

According to TG and DSC tests, thermal stability of ACR would be augmented by the introduction of APP-II. The addition of APP-II triggered lower maximum mass loss rate (MMLR), higher temperature corresponding to mass loss of 90% (T0.1), chars yield, and endothermic peaks. Consequently, the ACR dust explosion was inerted by the chemical interaction of ACR/APP-II mixtures and endothermic decomposition of APP-II.
