Abstract

The invention provides a treatment method of a waste colloidal emulsion explosive in a porous ammonium nitrate fuel oil explosive. Namely, the waste colloidal emulsion explosive is pre-treated to be mixed with porous ammonium nitrate or porous ammonium nitrate mixed with a certain amount of oil phase according to a certain ratio; corresponding technical parameters are adjusted according to technical requirements of a product so as to prepare the qualified porous ammonium nitrate fuel oil explosive, wherein a pre-treated waste colloidal emulsion explosive mixed solution accounts for 20.0-40.0% of the total weight of an explosive finished product, and the porous ammonium nitrate or porous ammonium nitrate mixed with the certain amount of oil phase accounts for 60.0-80.0% of the total weight of the explosive finished product. Compared with existing other treatment methods, the treatment method disclosed by the invention is simple in production process technology, and stable and reliable in product quality and has economical and environment-friendly effects; potential quality hazards and potential safety hazards which are generated by online addition of the waste colloidal emulsion explosive, as well as raw material waste and environment pollution which are caused by destroying and treating the waste colloidal emulsion explosive are avoided; the recycling and the reutilization of the waste colloidal emulsion explosive are realized, and the treatment method has more obvious economic benefits and social benefits.

Description

technical field [0001] The invention relates to a treatment method of scrapped industrial explosives, in particular to a treatment method of scrapped colloidal emulsion explosives in porous ammonium oil explosives. Background technique [0002] At present, the processing methods of scrap colloidal emulsion explosives mainly include the following types: [0003] (1) Add processing online. It is mainly aimed at the treatment of latex matrix or finished drug body with good milk quality. For the primary or secondary emulsification medium and low temperature sensitization production line, most of them manually add a small amount and multiple times directly from the feed port of the sensitization machine; for the high temperature sensitization production line, they add a small amount and multiple times from the latex matrix hopper in front of the sensitizing mixer. This method is the most simple and feasible, and most emulsion explosive manufacturers use this method to dispose o...
