Description
Technical field
The present invention relates to the emulsifying agent that one is applicable to emulsion explosive sensitization (foaming), and application in emulsion explosive preparation and mixed explosive technology.
Background technology
The development of nearly more than 40 years of industrial explosive process, by many kinds, progressively by having, formula and technique are simple for Alternative, the emulsion explosive of environmental protection, safety type and load in mixture car and replace, and develop into full-automatic intensive production line, and load in mixture car production technology, no matter adopt production line and the production that loads in mixture car, all there are some problems in present stage, one of them is sensitization technology, and this technology determines to do the quality of emulsion explosive, be the bottleneck of emulsion explosive development, restricted the development in an all-round way of emulsion explosive.
The sensitization of emulsion explosive mainly contains two kinds of forms, the one, physical sensitization, by solid matter, bubble is brought in emulsion matrix, makes emulsion matrix have detonator and explosive sensitivity, sensitization material generally has perlite, glass microsphere, float pearl or other is with leachy material; The 2nd, chemical sensitization, adds the chemical substance that can generate bubble, by stirring, evenly spreads in emulsion matrix, makes emulsion matrix have detonator and explosive sensitivity, and chemical foaming agent has H whipping agent, Sodium Nitrite, Calcium hydrogen carbonate etc. can produce the chemical substance of gas.
Two kinds of methods all have its strengths and weaknesses, the material that physical sensitization adds, and proportion is very light, while mixing with full-bodied emulsion matrix, be difficult to be uniformly dispersed, and sensitization material breakage rate effect high (being blended when sensitization), due to adding of solid matter, the emulsion explosive medicine body forming is harder, in the time of blasting explosives packing, and sensitization physical deterioration cylinder body and equipment, and cause powder charge pressure high, not only cause powder charge difficulty, also destroyed the sensitization bubble of explosive simultaneously, quality of explosive significantly declines.But it is less that physical sensitization is affected by the physical condition of temperature, emulsion matrix, use more general in south.
Chemical sensitization mainly adds generation chemical reaction, can produce the material of bubble, the aqueous solution often is easily uniformly dispersed in emulsion matrix, but the temperature of speed of response, gas production rate and emulsion matrix, and the quality of emulsion matrix is relevant, chemical sensitization environmental protection and explosive property and charging quality are better, storage period is long, but aftereffect serious (long reaction time, after several days or all explosive volume becomes large in transit, from packaging, leak out), and restive.
The reason 1 that chemical sensitization is restive: what emulsion explosive production line chemical sensitization generally adopted is Sodium Nitrite, add other mineral acid or directly add ammonium nitrate, form the aqueous solution, stir with emulsion matrix, the temperature general control of emulsion matrix is between 45～55 DEG C, and Sodium Nitrite optimal reaction temperature is 60～65 DEG C, if emulsion matrix temperature is 45 DEG C time, Sodium Nitrite react completely want several hours, even the time longer, affect quantity and quality.
The reason 2 that chemical sensitization is restive: (acidic substance are promotor) carried out in the reaction of Sodium Nitrite under acidic conditions, forming emulsion matrix is oil phase and water, ammonium nitrate itself in water just can react with Sodium Nitrite, ammonium nitrate is also the promotor of Sodium Nitrite, with the ammonium nitrate solution (emulsification) in the coated water of oil phase, the oil film forming is when stronger, ammonium nitrate is not exposed, reaction is just difficult to carry out according to design, in the time that oil phase oil film is thinner, the ammonium nitrate being wrapped by just may with Sodium Nitrite direct reaction, form air pocket, directly escape or because of ammonium nitrate concn high, react too fast, cause sensitization restive.
The reason 3 that chemical sensitization is restive: the Sodium Nitrite that body sensitized emulsion matrix is used is generally 2～3 times of Theoretical Calculation, main consideration antedating response and stirring are uneven, the surplus capacity reacting is participated at end, slowly react with the ammonium nitrate in emulsion matrix, after sensitization, to maintain several days time, bring the restive problem of chemical sensitization.
In view of emulsion explosive characteristic and formation mechanism, the microstructure of research emulsion matrix particle, according to emulsifying agent emulsification mechanism, on the oil film of emulsion matrix particle, with the promotor of Sodium Nitrite, as long as control temperature and stirring intensity well, emulsion matrix runs into the aqueous solution of sensitizing agent (Sodium Nitrite), concentration just can complete sensitized reaction with amount is all controlled within the time of design, the bubble forming is small and even, be all effective bubble, solved emulsion explosive sensitization in all cases completely.
