| Zusammenfassung: | The invention relates to an emulsion explosive with high power and strong hardness, which is characterized in that the emulsion explosive is prepared by the steps of crushing ammonium nitrate according to proportion by a crusher, adding the crushed ammonium nitrate and sodium nitrate into a melting tank filled with water according to proportion by a inclined spiral machine, stirring and heating to 115-125DEG C to prepare aqueous solution; stirring and heating semi-refined paraffin, Vaseline, crystallite wax, stearic acid and emulsifier according to proportion to 110-120DEG C to prepare oil phase solution; conveying the aqueous solution and the oil phase solution according to ratio of 94:6 to a emulsifying machine by a screw pump, making the aqueous solution excellently wrapped in the oil phase solution to form a water-in-oil type emulsification matrix, cooling to 43-57DEG C by steel strip, adding a sensitizing agent according to proportion, uniformly mixing, packaging and storing. The invention has advantages |
