Study On The Stability Of The Emulsion Explosive And The Method Of Characterizations

This paper summarizes the stability of the emulsion Explosives basic theory, and put forward the way how to improve the basic stability of emulsion Explosives. and refers to a basic component of emulsion Explosives and the production process in one production line of the emulsion Explosives, using different emulsifier, compounded emulsifier, the compounded oil in the Experiment. At last, we get the two excellent compounded emulsifiers, and also improve the basic component and the basic formula ratio of the emulsion Explosives.The experimental study on the technical conditions, such as the mixing of speed, shear strength, emulsifying temperature, time of emulsifying, which Influence the stability of emulsion Explosives, and finally we decide that the Experiment of the conditions and processes.The experiment also analyze the different current sensitized Methods of emulsion Explosives, and at the final, we select the method of chemical. And also select the five different temperature for the chemical sensitization of the emulsion Explosives .In the token methods,through the microscopic observation of emulsion Explosives and particle size distribution of the Test, the Test results of the samples can be judged the Stability according to the different components of emulsion Explosives, these are the Methods of judging the Stability of the emulsion Explosives from the micro-structure and the particle size distribution.Emulsion Explosives through the high low temperature cycle Experiment, the separation of ammonium nitrate and conductivity Tests,can also be determined the environmental storage stability. the titration Test, detonation velocity and conductivity Tests combined with the high low temperature cycle Experiment can measure the stability of the emulsion Explosives and Explosive properties of the samples better .and these certificated the Test results of the microscopic observation and the particle size distribution.Through the ability of emulsion Explosives underwater shock Tests and the change detonation of the different varieties emulsion Explosive by the impact load, we can determine all the stability of the emulsion Explosives samples. The data and calculation results show that the stability of the 6th and the 9th samples are better than other samples.Finally, through Testing the samples of the same composition and the different sensitivity conditions on the stability and the properties of the emulsion Explosives, we get that the sensitivity temperature at 65℃sensitized emulsion Explosive, whether it is the explosion or performance are superior to other samples, and also prove that the optimization of the Experimental varieties from the compound emulsifier, in the pharmaceutical not only to reduce the cost of production, but also has good storage stability and Explosive properties.
