Description
Technical field
The present invention relates to a kind of method improving Impact Sensitivity degree of accuracy.
Background technology
Much there is dangerous chemicals or the mixture of explosion tendency, all can be some as heat, light, electricity, friction etc.
Explode under initiation conditions, the impact sensitivity test of wherein explosion tendency is exactly a critically important test content.
The United Nations《Recommendation test with regard to Dangerous Goods Transport and manual of standards》In be referred to the world and state
Several devices of the interior impact sensitivity test for the chemical substance with explosion tendency or mixture, such as " bureau of explosives is hit
Hit equipment ", " federal examination of materials office drop-weight meter a ", " rood tester ", " 30 kilograms of drop-weight test meters ", " improved 12 types hit
Hit device " and " impact sensitivity assay device ".
CN202075211 discloses a kind of drop-weight test meter, including a cabinet, crane, weight, hits anvil and electronic
Machine, is provided with cabinet door in the front of cabinet, is arranged with the guide rail with plane perpendicular on the side wall of the left and right in cabinet two；Lifting
Frame is arranged between two guide rails, and the front end of crane is provided with cantilever, and the top of cantilever is connected with motor, and motor drives lifting
Frame slides up and down along two guide rails, is provided with, in the lower section of cantilever, the electric magnet that can adsorb or discharge described weight, hits anvil and be arranged on cabinet
The bottom of body, hits anvil and is provided with sample groove, and sample groove is located at the underface of weight.
But the test being carried out using said apparatus, its result judgement method is all to determine whether there is explosive sound by human ear,
This just makes the result of the test can only be by qualitatively judging, and precision be greatly reduced, because explosive sound is inconspicuous when even more many, very
Difficult Yu simple metal strike sound is differentiated, and causes to judge by accident.
The present invention targetedly solves the problems referred to above.
Content of the invention
The technical problem to be solved is that prior art has that degree of accuracy is relatively low, reliability is relatively low, carries
For a kind of method of new raising Impact Sensitivity degree of accuracy.The method is used for the evaluation of explosive mixture impact sensitivity
In, have the advantages that degree of accuracy is higher, reliability is higher.
For solving the above problems, the technical solution used in the present invention is as follows：A kind of raising Impact Sensitivity degree of accuracy
Method, comprises the following steps：（1）Carrying out in impact sensitivity test device using weight method, in the bar not loading test specimen
Under part, weight is installed, clashes into the adnexaes such as post according to test standard, hit close for the collection terminal of the sound collector of sound tester
Hit post fixing, then carry out bump test, sound frequency and decibel that record sound tester is recorded, using this data as
Blank assay；（2）According to（1）Step, tested in the case of filling test specimen, record sound frequency and decibel；
（3）Comparison step（1）With（2）Result of the test, if step（2）Test sound compared with step（1）High-frequency data and decibel occur
Improve, then can determine that for test specimen under this experimental condition, explode.
It is preferable that described blank assay should be under identical environment with the test having test specimen in technique scheme
Carry out or sound tester should have the function of removing environmental noise.
In technique scheme it is preferable that described blank assay and have test specimen process of the test in, weight height,
Weight, track, fixed form etc. should be consistent.
It is preferable that sample clashes into assembly by clashing into post, sealing shroud, rupture disk, clash into seat and heating in technique scheme
Oil bath form, test specimen groove be located at clash into seat in, sample cell is stamped rupture disk, sealing shroud by being threaded into shock seat,
Clash into post to be located in sealing shroud inner core, clash into post lower surface and contact with rupture disk, shock seat insertion heating oil bath inner core simultaneously will be whole
Individual sample clashes into assembly and is put on pedestal.
Due to the different test specimens with explosion tendency, it is different to the sensitivity performance clashing into, for portion
Divide the unconspicuous explosive of explosion phenomenon, explosive sound is mixedly appeared with simple metals strike note, only with the resolution capability of human ear very
Difficulty judges whether to explode.This patent pull-in frequency and decibel means of testing, are existed using explosive sound and simple metals strike note
This characteristic is clearly distinguished from frequency and decibel, replaces human ear to provide quantitative analytical data, be just easy to differentiate explosive sound or
Person is simple metals strike note, largely improves test degree of accuracy, the reliability of this test device, achieves preferable skill
Art effect.
Brief description
Fig. 1 is the structural representation of the method for the invention.
1 is fixed handle；2 is pick-and-place device；3 is scale；4 is weight；5 is draw-in groove；6 is guide rail；7 is sample shock group
Part；8 is pedestal；9 is sound collector；10 is sound tester.
Below by embodiment, the invention will be further elaborated, but is not limited only to the present embodiment.
Specific embodiment
【Embodiment 1】
On the assay device of evaluation explosive mixture impact sensitivity as shown in Figure 1, including pedestal, guide rail, weight, sample
Product clash into assembly and the fixation for weight and release device, and weight clashes into the sample on pedestal from top to bottom by guide rail
Product clash into assembly.
First under conditions of not loading test specimen, weight is installed, clashes into the adnexa such as post according to test standard, then by sound
The sound collection end of sound tester is near post and fixing near clashing into, and then carries out bump test, and record sound tester is remembered
The sound frequency of record and decibel, using this data as blank assay.With same step, tried in the case of filling sample
Test, record sound frequency and decibel.Described blank assay is carried out under identical environment with the test having test specimen.Blank examination
Test and have in the process of the test of test specimen, weight height, weight, track, fixed form etc. are consistent.
Relatively result of the test twice, if high-frequency data and decibel on the basis of blank assay in test sound
Improve, then can determine that for test specimen under this experimental condition, explode.
【Comparative example】
According to the method and steps described in embodiment 1, simply when carrying out the test of explosive mixture impact sensitivity not
Using sound tester and sound collector, in the case of equipped with test specimen, carry out bump test, examination is judged by human ear
Whether an explosion occurred to test sample.Test shows, when some test specimens occur slight blast, human ear is difficult to confirmation is
It is no that an explosion occurred.
