Rapid demulsifying agent for emulsified explosive and application thereof

Abstract

The invention discloses a rapid demulsifying agent for emulsified explosive and application thereof. The demulsifying agent is prepared from the following components according to the volume ratio: theratio of absolute ethyl alcohol to anhydrous petroleum ether is (1 to 1.5) to 1.5. The application of the demulsifying agent comprises the specific steps: weighing a test sample of the emulsified explosive or an emulsified matrix; adding the demulsifying agent into the test sample and uniformly stirring; adding a neutral formaldehyde solution and water into the test sample; dropwise adding an acid-base indicator and carrying out titration, so as to obtain the mass percent concentration C(NH4NO3)=0.1*V*0.08004*20 / M*100% of ammonium nitrate in the emulsified explosive or the emulsified matrix;the demulsifying agent can realize rapid demulsifying and detonation elimination of the emulsified explosive and the safety of the demulsifying and detonation elimination is improved; meanwhile, the invention also provides the application of the demulsifying agent; the component content of the ammonium nitrate in the emulsified explosive or the emulsified matrix can be rapidly and accurately determined, so that the power of the emulsified explosive is accurately detected, and furthermore, the needed utilization amount of different occasions is reasonably calculated and the utilization safety of the emulsified explosive is ensured.

Description

Technical field [0001] The invention relates to a demulsifier for emulsion explosives, and in particular to a rapid demulsifier for emulsion explosives and its application. Background technique [0002] Emulsion explosives use the action of emulsifiers to evenly disperse droplets of oxidants and salt aqueous solutions in an oil phase continuous medium containing porous materials such as dispersed bubbles or hollow glass beads, forming a water-in-oil (W / O ) emulsion-like water-containing industrial explosive is a new type of industrial explosive developed in the 1970s. The earliest emulsion explosives were non-detonator sensitive and had to be detonated with the help of relay detonators. Later, with the in-depth research on emulsion explosives, the emulsion explosives developed later also had detonator sensitivity and good water resistance. At the same time, it has the advantages of good explosive performance, low mechanical sensitivity and good safety. At the same time, the...

Problems solved by technology

In the safety of demulsification and demulsification, everyone is most concerned about the speed of demulsification, that is, after the emulsion explosive is mixed with the demulsifier, it is required to change the form of the emulsion explosive as soon as possible, so as to achieve demulsification and demulsification. The improved demulsifier has indeed improved the demulsification speed to a certain extent, but it still cannot meet the demulsification speed required by the industry

For today's demulsifiers, after mixing with emulsion explosives, it generally takes 1-2 hours to change the form of emulsion explosives and complete demulsification and detonation. This is far from meeting the requirements of rapid demulsification. Therefore, in the emulsion explosives production industry In order to improve the safety of demulsification and explosive demulsification, it is urgent to develop a demulsifier that can realize rapid emulsion explosive

[0005] In addition, the determination of the content of ammonium nitrate in emulsion explosives or emulsion matrix has always been a pain point, and it is difficult to ensure that the determination of ammonium nitrate components can be accurately and quickly achieved in a completely safe situation, that is, the current emulsion explosives or emulsion matrix The determination of the content of ammonium nitrate components in the medium is generally carried out under the condition of incomplete demulsification and elimination of explosion. The demulsification and detonation of the time, the follow-up measurement is difficult to ensure the accuracy of the results, and it takes a long time, so it is difficult to accurately detect the power of the emulsion explosive, and cannot fully guarantee the safety of the emulsion explosive
