Problems solved by technology

Emulsion explosives can show its superiority in blasting situations with water and humidity, but the current production process of emulsion explosives generally has low production capacity, low degree of automation, many on-line personnel and online charge, and many potential safety hazards in production. The storage stability and quality stability are still relatively poor, and further research is needed to improve

Abstract

The invention discloses a production method of an emulsified explosive, which comprises the following steps that: water phase and oil phase are prepared, and then water phase solution is added into oil phase solution to be emulsified by an emulsifier to prepare a latex matrix, and simultaneously a cooling steel strip controls the temperature of the latex matrix to be 90 to 105DEG C; and the matrix is cooled, the cooled latex matrix is added into a sensitizing machine, and then one or two of perlite and chemical blowing agent is added in for sensitization; and then the explosive is charged, and finally the loaded explosive is packaged to prepare the emulsified explosive. The production method of the emulsified explosive has the advantages of reducing the production cost, having no waste explosive, waste material, waste gas, waste water and dust in production, realizing the free switching of a plurality of sensitization methods, such as physical sensitization, chemical sensitization and physical and chemical composite sensitization, so as to meet the needs of different consumers; perlite is adopted for physical sensitization, and can improve the explosion performance and the storage performance; and the production method of the emulsified explosive can adapt to the requirements of small-diameter explosive charging and full-automatic packaging automatic calandria.

Description

technical field [0001] The invention relates to a production method of explosives, in particular to a production method of emulsion explosives. Background technique [0002] After more than 20 years of development in domestic emulsion explosive production, its good explosive performance and engineering blasting effect have been widely recognized, and many varieties have been developed, which are widely used in various civil blasting operations, and are useful for open-pit mine emulsification Explosives, rock-type emulsion explosives for medium-hard rock blasting, coal mine-approved emulsion explosives for underground coal mines, and small-diameter and low-velocity emulsion explosives for smooth surface blasting. Emulsion explosives can show its superiority in blasting situations with water and humidity, but the current production process of emulsion explosives generally has low production capacity, low degree of automation, many on-line personnel and online charge, and many ...
