Embodiment 1

[0014] Take 90kg of ammonium nitrate, 0.12kg of expanding agent, 0.01kg of sodium methylene bis-tetrasulfonate and 0.01kg of Span-80 and heat and dissolve in a melting tank containing 7.5 liters of water. The temperature is controlled at 120°C, and then 5kg of compound oil is added Stir and mix for 2 minutes; then suck the material into the expansion tank for vacuum expansion, the pressure in the expansion tank is -0.09MPa, and discharge the material after 9 minutes (at this time, the water has been completely evaporated); The mixture is added to the wheel mill for wheel milling, and 0.2kg of sodium octadecylamine acetate and 1kg of aluminum powder are added. The temperature of the wheel mill is controlled at 75°C; the powder after wheel milling is screened through an 8-mesh sieve, and then cooled to Below 45°C, the powder can be charged afterward.

Embodiment 3

[0020] Take 92kg of ammonium nitrate, 0.14kg of expansion agent, 0.02kg of sodium methylene bis-tetrasulfonate and 0.02kg of Span-80 and heat and dissolve in a melting tank containing 8 liters of water. The temperature is controlled at 125°C, and then 5.5kg of compound Stir and mix the oil phase for 3 minutes; then suck the material into the expansion tank for vacuum expansion, the pressure in the expansion tank is -0.09MPa, and discharge the material after 12 minutes (the water has been completely evaporated at this time); Add the mixture to the wheel mill and add 0.3kg of zinc octadecylamine acetate and 1.5kg of aluminum powder. The temperature of the wheel mill is controlled at 78°C; After cooling to below 45°C, charge the powder.

[0021] Above-mentioned bulking agent is the mixture of octadecyl primary amine zinc acetate, stearic acid and sodium stearate with a weight ratio of 50:25:25; : 20:10 Heat the mixture to 100-120°C and keep it warm for later use.

Abstract

The invention discloses an ANFO-expanded high-explosion-velocity seismic charge which comprises the following raw materials in parts by weight: 90-94 parts of ammonium nitrate, 0.12-0.15 part of swelling agent, 0.01-0.03 part of dispersant, 0.01-0.03 part of emulsifier, 5-6 parts of compound oil phase, 0.2-0.4 part of weighting agent and 1-2 parts of aluminum powder. The seismic charge disclosed by the invention has good explosive performance, TNT (Trinitrotoluene) poisonous substances are thoroughly canceled, and substances harmful to human bodies are not added or contained; the production environment is greatly improved compared with that of a traditional AN-TNT explosive, and the damage of TNT to the bodies of personnel is prevented; and the seismic charge has a simple production process with low production energy consumption, the components of the seismic charge do not contain any highly-sensitive substances, and the safety of production and transportation processes is higher.

Description

technical field [0001] The invention relates to the field of industrial explosives, in particular to an ammonium oil expanded high detonation velocity seismic source charge column. Background technique [0002] Industrial explosives are one of the indispensable basic energy sources for the development of modern industry, but the existing powdery seismic source charges contain TNT toxic substances, which cause certain pollution to the environment during the use process, which does not meet the current environment The social concept of protection, and during the production process of the powdered seismic source powder containing TNT toxic substances, TNT toxic substances will cause physical harm to employees, pollute the working environment of employees, and increase the hazards in the production process of explosives. Contents of the invention [0003] The technical task of the present invention is to provide an ammonium oil expanded high detonation velocity seismic source ...
