Study on Safety of Model II Powdery Emulsion Explosive

Abstract

Powdery emulsion explosive (PEE) invented by Ouqi Ni at the end of 1980s is a new kind of W/O industrial explosives. It has brought industrial explosives technology into a new era. Through years of development, Model I powdery emulsion explosive has been put into large scale production in more than 70 explosive manufacturers and is widely praised by its users. Through continuous research and improvements, Model II powdery emulsion explosive with better performance, longer shelf life and considerably lower cost has been successful invented. Given that safety is one of the most important factor in production, transportation and usage of industrial explosive, this paper is to evaluate the safeness of Model II PEE in terms of mechanical sensitivity, heat sensitivity, static electricity safety, and dust explosion risks. The testing results showed Model II PEE has achieved excellent safety level.
