Problems solved by technology

At present, emulsion explosives have the following problems: (1) the state of emulsion explosives is relatively soft, and during blasting operations, when filling blastholes, the powder rolls are easily deformed, damaged, and stick to the wall to cause plugging, which brings difficulties to charging. inconvenient
(2) Emulsion explosives are relatively hard, but the explosive power of the explosive is not high, and the storage period is short

Abstract

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 of hard state, high explosion power, long storage life, low production cost and high production safety.

Description

technical field [0001] The invention relates to an emulsified explosive, in particular to an emulsified explosive with high power and strong hardness. The object of the present invention is to aim at the existing defects and provide people with an emulsion explosive with hard drug state, high explosive power and long storage period, to be more precise, an emulsion explosive with high power and strong hardness. Background technique [0002] Emulsion explosive refers to the water-in-oil type water-containing industrial explosive prepared by emulsification technology. It emulsifies the oxidant aqueous solution and the oil phase solution through the action of an emulsifier to form a stable water-in-oil latex system. my country's emulsion explosives were developed and produced in the late 1970s. For a long time, emulsion explosives have generally been in a soft state, inconvenient to use, and oil leakage often occurs, especially in summer in the south. At present, emulsion explo...
