Abstract
The present invention is the prescription of primary explosive in the plastic low speed detonate-tube.Formerly mainly contain high explosive hexogen or octogen, therefore, produce, store and transportation all needs strict safety features and requirement of shelter, capital cost and production cost height with prescription.For overcoming the former problem of using prescription to exist, invented another kind of prescription, mainly be the high explosive that replaces former usefulness with oxygenant, thereby relatively safety also can be saved initial cost and be reduced cost.
Description
The present invention relates to the prescription of primary explosive in the plastic low speed detonate-tube.
Primacord is the main element of industrial explosive material plastic detonating tube nonel ignition system, and people are known, and the prescription of the primary explosive of being adorned in plastic detonating tube has two kinds both at home and abroad:
1. hexogen, aluminium powder and calcium stearate;
2. octogen, aluminium powder and calcium stearate.
Above-mentioned hexogen and octogen are high explosive, its mechanical sensitivity height, dangerous big, safety coefficient is little.Therefore, during with their production, storage and transportation primacord, need strict safety features and requirement of shelter." Code for safety design of ivil explosive materials manufacturing plants (trying) " regulation that the 5th design and research institute of Ministry of ordnance Industry formulated in 1984, the danger classes of producing and storing the buildings of hexogen or octogen is divided into the most dangerous A
1Level (is divided into A altogether
1, A
2, A
3, B, D Pyatyi), the required distance between the buildings is big.Therefore, floor space is wide, the expense height of safety features.
The objective of the invention is to overcome shortcoming of the prior art and a kind of prescription of safe primary explosive is provided.
The objective of the invention is to reach: replace original high explosive hexogen or octogen with oxygenant, oxygenant and aluminium powder and calcium stearate or talcum powder are mixed and form the primary explosive of primacord by following approach.Oxygenant can be selected saltpetre or Potcrate for use.
The present invention compared with prior art has following advantage:
1. low, the good stability of the mechanical sensitivity of oxygenant saltpetre or Potcrate and heat sensitivity compares safety, and level of security is I level (rank is high more, and safety coefficient is more little), and the high explosive hexogen that originally uses or the level of security of octogen are the III level.
2. the division of " Code for safety design of ivil explosive materials manufacturing plants (the trying) " of formulating according to the 5th design and research institute of Ministry of ordnance Industry 1984, the worker-house of oxygenant saltpetre or Potcrate (workshop), warehouse danger classes are divided into dangerous minimum D level, distance and floor space between buildings are little, and capital cost is less.
3. the toxicity of oxygenant saltpetre or Potcrate is little, has no irritating odor, and is little to human body harm.
4. the wide material sources of oxygenant saltpetre or Potcrate are not subjected to the restriction of public security department's safety rules.
5. the cost of oxygenant saltpetre or Potcrate is low, is about half of high explosive.
Further narrate the present invention by the following examples: count the Potcrate of 50-80% of primary explosive or saltpetre and aluminium powder in order to weight and mix the primary explosive of forming in the low speed detonate-tube for calcium stearate or the talcum powder of the 1-5% of primary explosive by weight, its explosion velocity is the 800-1200 meter per second, the technical feature that meets primacord, suitable for producing is used.
Claims (5)
1, the primary explosive in the low speed detonate-tube that mixes by high explosive hexogen or octogen and aluminium powder and calcium stearate, its characteristics are to replace high explosive hexogen or octogen with oxygenant, and calcium stearate can replace with talcum powder.
2, the oxygenant in the low speed detonate-tube as claimed in claim 1 can adopt saltpetre or Potcrate.
3, the amount of low speed detonate-tube inner oxidizing agent saltpetre as claimed in claim 2 or Potcrate is the 50-80% of primary explosive by weight.
4, the primary explosive in the low speed detonate-tube as claimed in claim 1 contains calcium stearate or talcous amount, is the 1-5% of primary explosive by weight.
5, the detonating velocity of the low speed detonate-tube of employing saltpetre as claimed in claim 2 or Potcrate is the 800-1200 meter per second.
