Problems solved by technology

This makes the high temperature sensitization method inevitably embarrassing: no or less expensive high-energy materials are added to reduce production costs, which will make the explosives less powerful and unable to meet the needs of users, and users will not adopt them; if adding expensive high-energy materials Energetic materials will greatly increase the production cost and affect the profit of the explosives factory; (2) From the perspective of its explosive performance, it is high temperature sensitized and has large bubbles, resulting in low detonation velocity, detonation, and low violence; (3) Bubbles large, poor storage stability
For this reason, if adding expensive microcrystalline wax with a high melting point, the cost will increase; (4) high temperature sensitization reduces intrinsic safety; The risk of follow-up charging is reduced, especially the amount of medicine stored in the workshop is increased.
[0006] Although low-temperature sensitization (below 55°C) eliminates the above-mentioned disadvantages of high-temperature sensitization, it is not easy to charge, the efficiency of charge decreases, the error of charge increases, and the number of operators increases.

Abstract

The invention discloses a preparation method of mild sensitization in an emulsion explosive. The inventive preparation method comprises pre-cooling the colloid emulsified from the emulsion explosive to 60 to 70 degrees centigrade, then under the aforementioned temperature, implementing chemical or complex sensitization, and directly loading the explosive to stock. As the mild sensitization is adopted, the power of the explosive is further enhanced, the bubble quality is improved, the explosive property is improved, the cost is reduced, and the explosive storage quantity in the factory is reduced. The inventive manufacturing method is characterized by simple technical, safe manufacturing process, qualified product property, stability and reliability.

Description

technical field [0001] The invention relates to a preparation method of medium temperature sensitization of emulsion explosive, in particular to a preparation method of medium temperature sensitization of emulsion explosive without TNT and having high explosive performance. Background technique [0002] The continuous production line of emulsion explosives was first patented by Atlas Gunpowder Company of the United States in 1978. In China, successively in 1985, the Changsha Research Institute of Mining and Metallurgy built a continuous line at the Dabaoshan Copper Mine in Guangdong, and the Changsha Research Institute of Mining and Mining at the Shougang Qian'an Iron Mine and identified them. Later, on the basis of introduction and digestion, Changsha Mining Research Institute built a computer-controlled continuous production line in Daye Iron Mine, Hubei in 1990. [0003] After 30 years of development, emulsion explosives are becoming more and more popular in the civil ex...
