Abstract
The invention provides a non-explosion detection method of large emulsion explosives. The method is characterized by comprising the steps of detecting the content of free-state ammonium nitrate in the quantitative explosives and detecting the density of the explosives. Whether the explosives are qualified or not is judged by detecting the content of free-state ammonium nitrate in the large emulsion explosives and detecting the density of the large emulsion explosives, namely, the two measured data are compared with the standard indexes, if the two data are qualified, the explosives are judged to be qualified, and if one of the two data is disqualified, the explosives are judged to be disqualified. The method has the following advantages: numerous defects of detection with the explosion method are avoided; and not only is the operation simple and convenient and the efficiency high, but also the pollution and noises are avoided and the testing results are accurate.
Description
Technical field
The present invention relates to a kind of nothing blast method of inspection of big specification emulsion [explosive.
Background technology
Big specification paste emulsion explosive is one of commercial explosive that is widely used in large-scale perron quarry blasting, is the more and bigger emulsion [explosive explosive (its explosive density is at 1.25-1.35g/cm3) of cartridge density of single powder stick dose of a class.Generally speaking, it does not possess cap-sensitivity, so adopt explosion method to need initiating explosive to ignite it.All the time, people test its explosion property by explosion method, thereby learn whether its performance satisfies national standard.Yet, when using explosion method to check this series products, because it is more that the list of big specification emulsion [explosive props up the powder stick dose, so require the testing field that the approval of local public security organ will be arranged simultaneously in remote area and certain abstinence scope arranged, bring noise, vibrations and dust to surrounding environment, thereby be unfavorable for environmental protection; And blast the time consumed relevant initiating explosive, detonator and explosive, causes the waste of resource.Therefore adopt a kind of novel environment friendly, the method for inspection energy-conservation, easy to use to check the performance of big specification paste emulsion explosive, have very big reality to need and meaning.
Summary of the invention
The invention provides a kind of nothing blast method of inspection of big specification emulsion [explosive, judge the emulsification index of emulsion [explosive by free state ammonium nitrate content in the mensuration emulsion [explosive, and measure the density of emulsifying fixed quantity explosive, judge the performance of explosive by the test result of two aspects.This method is easy and simple to handle, efficient is high, and pollution-free, noiseless, and test result is accurate.
Purpose of the present invention is achieved through the following technical solutions:
A kind of nothing blast method of inspection of big specification emulsion [explosive, it forms content and check explosive density that step comprises free state ammonium nitrate in the quantitative explosive of check.The present invention judges the emulsification index of emulsion [explosive by free state ammonium nitrate content in the mensuration emulsion [explosive.The used emulsified bases of emulsion [explosive is to adopt the emulsifying technology will be based on the water of high concentration ammonium nitrate and the Water in Oil emulsion that forms under the effect of emulsifying agent based on the oil phase material of wax class, aborning, if emulsification gets bad, the emulsion [explosive that forms will occur whole or half water particle is not coated by oil phase, only be temporary in the oil phase, in a single day the ammonium nitrate particle that these polarity are very strong is immersed in water to dissociate soon and is ionic condition in water, so, water is cooked medium and is soaked gel, adopt formaldehyde method to determine the content of free ammonium nitrate quantitatively again, the size of content has shown the quality of sample emulsification, can directly react the emulsion quality of emulsified bases, promptly utilize water to examine the compactness and the intensity of gel interfacial film, reach the purpose of the emulsification index of the big specification emulsion [explosive of preliminary judgement as intensified condition.
The emulsification index of simple judgement emulsion [explosive is to satisfy client's request for utilization, therefore also needs the mensuration of other index.Usually, the emulsion [explosive that can use is that emulsified bases that emulsification is good changes emulsified bases density by the sensitization mode and makes it have sensitivity and power requirement that the user uses.See that with regard to the detonation sensitivity aspect in certain density range, density is littler, sensitivity is higher, but considers that from the angle that explosion is used the reduction of density must cause the corresponding decline of explosive strength, unfavorable to demolition effect, so the density of emulsion [explosive will be controlled just rightly.Therefore, can judge the height of its detonation sensitivity by measuring big specification Density of Emulsion Explosive.
By the mensuration to extensive emulsion [explosive emulsification degree and density, synthesis result is evaluated, and can check the performance of extensive emulsion [explosive efficiently, this kind method has been avoided many defectives of explosion method check, not only easy and simple to handle, efficient is high, and pollution-free, noiseless, test result is accurate.
Description of drawings
According to embodiment and accompanying drawing the present invention is described in further detail below.
Fig. 1 is the nothing blast method of inspection schematic flow sheet of a kind of big specification emulsion [explosive of the present invention;
Embodiment
As shown in Figures 1 to 3, provided the schematic flow sheet of the nothing blast method of inspection of a kind of big specification emulsion [explosive of the present invention, checking procedure of the present invention and the used method of each step have been showed among the figure, as seen from the figure, when measuring emulsion [explosive emulsification degree, earlier accurately take by weighing the 20.00g sample, place 180ml distilled water, temperature is controlled at 20 ℃, continue to soak after 24 hours, the aqueous solution that accurately pipettes after the 25ml submergence with transfer pipet places conical flask, adds neutral formalin solution 10ml, 2 of phenolphthalein indicators, with the standard solution titration of the NaOH of working good to blush, keep 30 seconds colour-fast, be titration end-point, every group needs replicate determination twice.Then the data based formula that draws:
In the formula: the amount of V-NaOH that titration consumes, unit is ml; The volumetric molar concentration of N-standard hydrogen sodium oxide molybdena, unit is mol/ml;
The every group of row of making even measured the mean value that differs less than two class values of 0.01g, as the measured value of this group sample.According to index request, judge whether tested sample is qualified then.
To carry out the test of Density of Emulsion Explosive on the other hand, take by weighing explosive sample 100g, be accurate to 0.5g, slowly the explosive of weighing is put into the graduated cylinder that 300ml water is housed, vibrate graduated cylinder gently, the drum of explosive surface adsorption is discharged, after treating that water surface rising is steadily fixed, write down the volume of water in the graduated cylinder of water surface rising back, estimate and read, then according to formula to 1ml
ρ=m/(v2-v1)
ρ is a density in the formula, and m-quality of explosive, unit are g, and V2 is a volume of putting into water behind the explosive, and unit is mL, and V1 is a volume of putting into water before the explosive, and unit is mL.
Its arithmetic mean is got in replicate determination twice, and the gained result should represent to two decimals.
According to the data that record, with normal data relatively, if two are all qualified, then emulsion [explosive is qualified, if having one defective, then be judged to be defective.
