Embodiment Construction

[0017] The present invention is further illustrated below by way of examples. The embodiments of the present invention are only used to illustrate the present invention, but not to limit the present invention.

[0018] When preparing methane-storing glass microsphere sensitized emulsion explosives, first, according to figure 1 The continuous ventilation device shown in the figure produces methane-storage glass microspheres. The specific steps are: 1. Open the inlet and outlet 7, put the glass microspheres into the continuous ventilation main body 3, close the inlet and outlet 7, and turn off the exhaust switch 2. Open the intake switch 4, fill the continuous ventilation body 3 with methane gas through the intake pipe 5, until the pressure is 3MPa, close the intake switch 4, open the exhaust switch 2, and discharge the methane air mixture through the exhaust pipe 1 Gas, the pressure at the exhaust pipe 1 is normal pressure, the exhaust pipe 1 can be connected to the exhaust ga...

Abstract

The invention relates to methane storing type glass microsphere sensitized emulsion explosive and a preparation method. The emulsion explosive consists of an aqueous phase, an oil phase and methane storing type glass microspheres; an emulsion matrix is prepared by emulsifying the aqueous solution and the oil phase; the mass ratio of the methane storing type glass microspheres to the emulsion matrix is (1.5-3.5) to 100; a methane storing type glass microsphere sensitizing agent is prepared by a continuous gas exchange device; the methane stored in the methane storing type glass microspheres accounts for 58-85% by mass; the methane stored in the methane storing type glass microspheres realizes a sensitizing effect as well as an effect of increasing the explosion energy and the gas content ofexplosive products, and enhances the explosion performance of the emulsion explosive; moreover, since the methane is a clean, high-energy and cheap gas, the methane storing type glass microsphere sensitized emulsion explosive has a broad application prospect.

Description

technical field [0001] The invention belongs to the technical field of performance improvement and preparation of emulsion explosives, and relates to a methane-storage glass microsphere sensitized emulsion explosive and a preparation method, in particular to glass microspheres storing methane gas as a sensitizer, preparing a new type of emulsion explosive and a preparation method, The purpose of improving the performance of the emulsion explosive is realized. Background technique [0002] With its special water-in-oil (W / O) structure, emulsion explosive has good waterproof function and is widely used in blasting engineering. Emulsion explosives are usually composed of oil phase, water phase and sensitizer, and sometimes a small amount of additives are added to achieve some special engineering purposes. Among them, the oil phase is usually composed of oil, paraffin and emulsifier, and sometimes lipids are also considered; the water phase is usually composed of water, ammoniu...
