Description

Technical Field

[0001] The invention relates to the technical field of latex explosives, and in particular to a method for controlling the sensitized temperature of a latex explosive blast hole. Background Art

[0002] Latex explosives generally refer to a class of water-in-oil emulsion-type water-resistant industrial explosives prepared using emulsion technology. Due to their excellent water resistance, wide raw material availability, low production cost, good safety performance, and wide adaptability, latex explosives have become a promising industrial explosive. Sensitization temperature significantly affects the explosive performance and stability of latex explosives. Higher sensitization temperatures reduce the viscosity of the emulsion matrix, accelerate the chemical reaction rate of the foaming agent, and reduce the foaming and emulsification retardation effect. However, this also increases the bubble overflow rate, which is detrimental to the formation of hot spots and the sensitization effect of the emulsion explosive. Lower sensitization temperatures increase the viscosity of the emulsion matrix, hindering the forward chemical reaction of the foaming agent and affecting the sensitization effect of the emulsion explosive. Therefore, both excessively high and low sensitization temperatures are detrimental to the sensitization of emulsion explosives. However, in the existing technology, the temperature of the latex matrix is not controlled, resulting in the sensitization temperature of the latex matrix in the blasting hole not meeting the sensitization process, thereby passivating the latex matrix and causing the blasting hole to refuse to explode, ultimately bringing safety hazards and cost waste to the blasting area.
