Abstract

The invention provides special oil for viscous granular emulsion explosives. Jinan refinery resources are reasonably used, intermediate materials are adopted, distiller first vacuum side stream, diesel of a lubricating oil hydrogenation device, first vacuum side stream, light lubricating components and the like serve as raw materials, and the special oil for the viscous granular emulsion explosives is produced by a blending process and is stable in property, low in volatility, environmentally friendly, low in cost, rich in source and stable in price. The explosives prepared from the explosive oil are good in blast propagation distance and brisance (steel tube confinement) and have longer peak value duration.

Description

technical field [0001] The invention relates to a special oil for viscous granular emulsified explosives, which belongs to the technical field of petrochemical products. Background technique [0002] Viscous granular emulsified ammonium oil explosive is a new type of ammonium oil explosive. It is a product obtained by mixing porous granular ammonium nitrate emulsified matrix with ammonium nitrate, oil phase components and sulfur powder. It has certain fluidity and adhesion, good explosive performance and low cost. Low, can effectively solve the problem of waste and environmental pollution caused by the excessive amount of ammonium oil returned when the air-compressed charge machine sucks granular ammonium oil into the blast hole, and the market situation and application prospect are good. In addition to acting as a combustion agent in the explosive, the oil phase component is more important to the storage performance of the finished explosive. Therefore, the viscosity of th...
