Description
Technical field
The present invention relates to a kind of method of testing, be specifically one kind in vacuum environment test dangerous goods in solid form combustibility or
The method of explosion property.
Background technology
At present, vacuum is extracted as a kind of conventional means by the substantial amounts of drying applied to dangerous goods in solid form and packaging,
Purpose is starvation supply, and reduction is dangerous.However, there is quite a few to belong to solid hazardous from oxygen supply in dangerous goods in solid form
Product, even if they have completely cut off oxygen, still can burn or explode.Only understand fully that dangerous goods in solid form fires in vacuum environment
The fierce degree burnt and exploded, could be accurately qualitative to its danger progress, also can just determine that vacuum environment whether can
Reduce the danger of dangerous goods in solid form.Such burning examination is generally carried out using special dangerous goods in solid form vacuum test case at present
Test, such equipment price is higher and operation is more complicated, and once have explosivity the bearing beyond test box of unknown sample
Scope, then can cause measurement equipment partially or completely to damage, cost is very high.It is badly in need of a kind of testing cost at present cheap, it is easy to operate
Carry out the combustibility or explosion property of preliminary test dangerous goods in solid form in vacuum environment with method of testing easy to spread.
The content of the invention
The technical problems to be solved by the invention are to provide one kind and dangerous goods in solid form combustibility are tested in vacuum environment
Or the method for explosion property, available for the burning of dangerous goods in solid form in vacuum environment or explosion hazard primary dcreening operation, surveyed meeting
While examination needs, testing cost is reduced.
The present invention, which is adopted the following technical scheme that, to solve the above problems：
The method that the present invention tests dangerous goods in solid form combustibility or explosion property in vacuum environment, it includes following behaviour
Make step：
1) sample is loaded into polybag；
2) polybag is pierced into at the end of igniting of electronic ignition head and inserts sample center, then polybag is put into test block
Test trough in form positioning, the power connection end of electronic ignition head is placed on the outside of test trough through connection after test trough and test block
Infrared remote control igniter；
3) sample, test block, electronic ignition head and infrared remote control igniter are fitted into transparent hermetic bag in the lump；
4) hermetic bag is evacuated, infrared remote control igniter is excited with remote control, electronic ignition head is ignited sample, sight
Examine the phenomenon that sample burns or exploded in vacuum environment.
Test block of the present invention is the cube or cuboid or spheroid framework of hollow out, its edge be fillet to prevent
Only cut hermetic bag.
The bottom of test block of the present invention is provided with the test trough for being used for accommodating sample, the side of test trough and test block
Framework provided with supplied for electronic igniter head power connection end stretch out hole.
Compared with prior art, the invention has the advantages that：
1) test articles for use are with low cost.Because test block can be printed out directly with PLA material 3d, cost is about 10
Member；Hermetic bag can use commercially available storage vacuum compression bag, and cost is about 5 yuan；Normal domestic use dust catcher can be used by extracting vacuum；It is infrared distant
It is commercially available fireworks and firecrackers igniter to control igniter and igniter head, and cost is about 60 yuan；No. 5 batteries 4 are saved, and cost is about 4 yuan.Entirely
Portion's test material cost, which is added, is no more than 80 yuan of RMB.The danger of combustion and explosion hazard of dangerous goods in solid form are before the test
Can not accurately it estimate, fierce burning or blast more than expected happens occasionally, if directly entered in expensive vacuum test case
OK, very big loss can be caused.Such as using the inventive method, the general only meeting cost depletions of inviolent experiment of burning are 1 yuan of electricity
Sub- igniter head；It is 10 yuan that burning or somewhat violent experiment of exploding, which may damage the vacuum compression bag that cost is 5 yuan and cost,
Test block；For violent experiment of burning or explode, can after evacuation by one piece of isolated brick be pressed in IR remote controller and
In the middle of test block, it would be possible to occur the part isolation of vigorous combustion and blast, conservation value highest infrared remote control igniter；I.e.
Make in test to occur beyond expected burning or explode, all test articles for use are damaged completely, loss still very little.
2),, can also be right if vacuum compression bag is not damaged after the completion of experiment due to using sealed vacuum compression bag
Dangerous goods in solid form is burnt or explosion gases is collected, for measuring and analyzing, and assesses the danger of gas.
Brief description of the drawings
Fig. 1 is the test block structural representation used in the inventive method.
Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
As shown in figure 1, cube frame structure of the test block that uses of the inventive method for a hollow out, or long
Cube or spheroid frame structure, its edge is for fillet to prevent from cutting hermetic bag, and the bottom of test block, which is provided with, to be used to accommodate sample
Test trough 11, the side of test trough is provided with hole 12, and the prism of corresponding test block is provided with hole 13.
The present invention tests the method for dangerous goods in solid form combustibility or explosion property, concrete operation step in vacuum environment
It is：
1) sample is loaded into polybag first, to prevent sample dispersion when vacuumizing；
2) end of igniting of electronic ignition head is put into the middle of test block through polybag insertion sample center, then by polybag
Test trough 11 in positioned；Connect behind the hole 13 that the power connection end of electronic ignition head is each passed through on the hole 12 and prism of test trough
Connect infrared remote control igniter；
3) sample, test block, electronic ignition head and infrared remote control igniter are fitted into transparent hermetic bag in the lump；
4) hermetic bag is evacuated, infrared remote control igniter is excited with remote control, electronic ignition head is ignited sample, sight
Examine the phenomenon that sample burns or exploded in vacuum environment.
The following is the application example of the inventive method, combustibility or the blast of 5g nitrocotton are tested under vacuum conditions
Performance：
Dried nitrocotton 5g is put into the polybag with sealing, drawing for electronic ignition head is inserted at nitrocotton center
Fire end.The polybag that will be equipped with nitrocotton is put into test trough 11 in test block, and the power connection end of electronic ignition head passes through test trough
Infrared remote control igniter is connected behind hole 13 on 11 hole 12 and test block on correspondence prism.By nitrocotton, polybag, electronics point
Duration and degree of heating, infrared remote control igniter and test block are fitted into commercially available storage vacuum compression bag together, with domestic vacuum cleaners by compressed bag
In air extract out.The position of high-speed camera is adjusted, can be observed by the hollow part of square in test trough
Sample.High-speed camera is opened, infrared remote control lights nitrocotton.All nitrocottons whole all burnts in 0.1 second, belong to quick-fried
Fried phenomenon.Vacuum compression bag is not damaged, and gas is rufous in bag.Gas volume is 436 milliliters after collection, is detected as two
Nitrogen oxide.Result of the test is：Dry nitrocotton, which belongs to, is ignited rear directly hair from oxygen supply type dangerous goods in solid form, vacuum environment
Raw blast；Experiment produces nitrogen dioxide gas, toxic.
