preparation example Construction

[0031] The raw materials for the preparation of the emulsion explosive include 81.72wt% to 88.42wt% of ammonium nitrate, preferably 83wt% to 86wt%.

[0032] The raw materials for the preparation of the emulsion explosive also include 0wt%-5.3wt%, preferably 1wt%-4wt%.

[0033] The raw materials for the preparation of the emulsion explosive also include 11.58wt% to 12.90wt% of water, more preferably 11.6wt% to 12.5wt%.

[0034] The raw materials for the preparation of the emulsion explosive also include 5wt%-7wt% of the integrated oil phase, more preferably 5.5wt%-6.5wt%.

[0035] The emulsion explosive is prepared according to the following method:

[0036] a) Water phase preparation of emulsion explosives:

[0037] The ammonium nitrate and sodium nitrate are dissolved in water to obtain a water phase; the temperature at which the ammonium nitrate and sodium nitrate are dissolved in water is 100-110°C.

[0038] b) Oil phase preparation of emulsion explosives:

Abstract

The invention provides a treatment method of emulsified waste medicine. The method comprises the steps that porous granular ammonium nitrate, diesel oil and emulsified waste medicine are mixed according to the mass ratio of (60-72):(3-5):(25-35). The emulsified waste explosive can be recycled through simple mixing at normal temperature, the obtained industrial explosive has certain free-running property and certain cohesiveness, and the obtained product has the advantages of the low cost, the good performance and the good safety, and can meet the requirements of open-air rock blasting engineering for explosion performance. Compared with an existing treatment method of emulsified waste medicine, the emulsified waste medicine can be well recycled, the treatment process is safe, simple and environmentally friendly, and obvious economic benefits and social benefits are achieved.

Description

technical field [0001] The invention belongs to the technical field of industrial explosives, and in particular relates to a treatment method for emulsified waste explosives. Background technique [0002] Emulsion explosives are a kind of water-in-oil industrial explosives prepared by emulsification technology, and are a kind of industrial explosives developed by the state. However, in the production process of emulsion explosives, a large amount of waste emulsion explosives will be produced due to improper process control, or operational errors or environmental factors, and the emulsion explosives have been placed for a long time and have expired and deteriorated. [0003] The waste of emulsion explosives will bring a lot of trouble to the production of enterprises. If the destruction process is carried out directly, it will not only bring huge economic losses to the enterprise, but also have potential safety hazards during the destruction process. If it is shelved for a ...
