Embodiment Construction

[0024] Add 50kg of water to the water phase tank automatically and quantitatively through the flow meter. When the water temperature rises to 65°C, add 800kg of crushed ammonium nitrate, 50kg of sodium nitrate, crystal form modifier (potassium nitrate, potassium sulfate, potassium chloride) , Potassium carbonate, Potassium thiocyanate, Potassium fluoride, Potassium chromate, or a mixture of two or more of the above-mentioned potassium salts) 60kg into the water phase tank, start stirring at the same time, continue heating to 100-120 ℃, heat preservation for later use; add 50kg of composite wax into the oil phase melting tank, and when the temperature of the oil phase reaches 60-80°C, add 15kg of emulsifier (ester or / and amide emulsifier), stir evenly, and continue heating to temperature to 100-120°C, keep warm for later use; pass the prepared oil and water phase solutions through their respective filters and metering pumps, and continuously enter the emulsifier for emulsificati...

Abstract

Pressure-resistant high-power emulsified seismic source powder column and its preparation method, the ratio of raw materials is: ammonium nitrate 74-92, sodium nitrate 0-11, crystal modifier 0-16, water 3-10, composite wax 4 ~6, emulsifier 1~2, microsphere foaming agent 0.1~1, aluminum powder 3~6. The method includes: A, water phase solution preparation; B, oil phase solution preparation; C, continuous emulsification; D, high temperature sensitization and addition of aluminum powder; E, automatic drug charging; F, sealing, cold medicine, packaging. The invention has the advantages that: the pressure-resistant high-power seismic source charge column has good pressure-resistant performance, can detonate normally when the pressure in deep water is 0.3 MPa, and has high explosive power. At the same time, since the density regulator used is a microsphere foaming agent, it can be sensitized under the condition of 100-120°C. The sensitized material has a high temperature and good fluidity, which is beneficial to the automatic powder filling machine. Improve work efficiency.

Description

technical field [0001] The invention belongs to civil blasting equipment, and in particular relates to a pressure-resistant high-power emulsified seismic source charge in the field of seismic exploration and a preparation method thereof. Background technique [0002] The existing emulsified seismic source charge generally has poor pressure resistance, and it is difficult to initiate detonation in deep water due to high environmental pressure. Moreover, the power of emulsion explosives is generally small. In addition, during processing, since the density regulator used is not suitable for high temperature use, the emulsified matrix produced must be cooled to 45-55°C through a special cooling process before the density regulator can be added to the kneader at 45-55°C. Sensitization is carried out under certain conditions. Due to the low temperature and poor fluidity of the sensitized material, it is not conducive to automatic charge machine charging, or the density of the cha...
