Abstract

The invention relates to a static emulsification-pumped latex matrix on-line continuous sensitized emulsion explosive manufacturing process which comprises the following steps: A. preparing a water phase solution, and preparing a compound oil phase; B. carrying out pre-emulsification mixing and static emulsification; C. cooling; D. pumping the latex matrix; E. mixing; F. forming a plastic film, and sealing; and G. cooling the explosive cartridge, and packing the explosive cartridge. The invention enhances the intrinsic safety of explosive charging, implements high-productive-capacity continuous explosive charging and on-line continuous sensitization, enhances the productive capacity of the existing low-temperature sensitized production line steel belt (maximum 100%), reduces the on-line explosive storage amount, and enhances the explosive charging efficiency.

Description

technical field [0001] The invention relates to the field of emulsion explosive production technology. Background technique [0002] At present, the low-temperature sensitization process of emulsion explosives includes water phase liquid preparation, composite oil phase preparation, emulsification process, cooling process, sensitization process and automatic charging process, cold medicine, tundish sealing, and packaging; the temperature of the sensitization process is 43-55°C, its main feature is to first sensitize the latex matrix into an emulsion explosive, and then add it to the charge process in a discontinuous manner. The charge machine equipment used is the filling equipment including the pumping device. After chemical charging, the emulsion explosive sensitized at a temperature of 43-55 °C, its sensitization point is gradually destroyed with the increase of charging speed and pressure, which is directly reflected in the fact that the density of the emulsion explosive...

[0002] At present, the low-temperature sensitization process of emulsion explosives includes water phase liquid preparation, composite oil phase preparation, emulsification process, cooling process, sensitization process and automatic charging process, cold medicine, tundish sealing, and packaging; the temperature of the sensitization process is 43-55°C, its main feature is to first sensitize the latex matrix into an emulsion explosive, and then add it to the charge process in a discontinuous manner. The charge machine equipment used is the filling equipment including the pumping device. After chemical charging, the emulsion explosive sensitized at a temperature of 43-55 °C, its sensitization point is gradually destroyed with the increase of charging speed and pressure, which is directly reflected in the fact that the density of the emulsion explosive roll after charging is greater than that of the charging powder. The density of the pre-sensitized emulsion explosive, and the density of the roll increases with the increase of the charge capacity, which eventually leads to the decrease of the detonation distance of the emulsion explosive roll or the loss of explosive performance, which is difficult to meet the use requirements, which greatly affects the Current emulsion explosive product performance and production capacity of manufacturing process technology
