Content of the present invention is the manufacturing process of emulsion explosive, comprises that surface facility is processed into normal temperature pumping latex matrix on latex matrix and the explosive loading truck, continuous sensitization two portions and a kind of normal temperature pumpable emulsion explosive loading car for realizing that above-mentioned technology designs.Existing division is as follows:
(1) preparation of surface facility latex matrix:
Emulsion explosive is made up of multiple component, the compositing formula of emulsion explosive of the present invention following (%):
Nitrate: 60～85
Water: 8～15
Urea: 3～5
Machine oil: 1～6
Paraffin: 0.5～3
Emulsifying agent: 0.5～2
Latex matrix is by aqueous phase substance and oil phase material, in the presence of emulsifying agent, selects optimal temperature, forms through violent stirring.
Water is by being the saturated aqueous solution of main oxygenant with ammonium nitrate, for reducing ctystallizing point and regulating oxygen-supplying amount in the blast process with addition of suitable SODIUMNITRATE.But the aqueous crystallization point that this two salt, one water is formed is higher than 75 ℃, determined pumping temperature (＞75 ℃) under hot conditions to carry out, it is higher that explosive is gone into big gun hole temperature like this, primacord there is the effect of thermal softening, also can dissolve simultaneously primacord fuse surface waxing face, reduce water resistance, and 75 ℃ pumping temperature is difficult to guarantee at extremely frigid zones.For reducing temperature and adapting to the pumping condition of difference variation big (20～45 ℃), the present invention adds urea at aqueous phase, and add-on is not less than 3%, can make the latex matrix pumping at normal temperatures of making, and can bear and powerfully (can reach 5kg/cm
2) extruding and friction and not crystallization and breakdown of emulsion.
Oil phase material viscosity size has a significant impact the flowability of latex matrix, selects for use machine oil and paraffin to regulate oil phase viscosity, and the latex matrix of making can pumping in 20～70 ℃ of temperature ranges.The proportioning of machine oil and paraffin is 3: 1～5: 1.
The adding of emulsifying agent is that the fine droplet of aqueous phase substance is evenly dispersed in the oil phase.
The manufacturing process of latex matrix is: by the prescription metering paraffin, machine oil, emulsifying agent are added to dissolve to heat in the still and dissolve, melting temperature is 85～95 ℃, puts into the emulsification still after dissolving.Meanwhile, drop into water, ammonium nitrate, SODIUMNITRATE and urea by the prescription metering in the jar successively toward dissolving, intensification is dissolved, and when treating that temperature reaches 100～110 ℃, aqueous phase solution is put into lentamente the oil phase of emulsification still under violent stirring.The aqueous phase solution flow control is 85～95 ℃ at 120～150 liters of/minute emulsifying temperatures, emulsification 15 minutes.Latex matrix is made back cooling insulation and is stored (15～50 ℃).
(2) the continuous sensitization big gun of normal temperature pumping hole patent medicine on the explosive loading truck
