Description
Technical field
The present invention relates to a kind of test method, it is specifically a kind of in vacuum environment test dangerous goods in solid form combustibility or
The method of explosion property.
Background technique
Currently, drying and packaging that vacuum is largely applied to dangerous goods in solid form as a kind of common means are extracted,
Purpose is starvation supply, reduces risk.However, there have quite a few to belong in dangerous goods in solid form to be solid hazardous from supplying oxygen
Product still can occur to burn or explode even if they have completely cut off oxygen.Only understand fully that dangerous goods in solid form fires in vacuum environment
The fierce degree burnt and exploded, could be accurately qualitative to the progress of its risk, also can just determine that vacuum environment whether can
Reduce the risk of dangerous goods in solid form.Generally use dedicated dangerous goods in solid form vacuum test case at present to carry out such burning examination
It tests, such equipment price is higher and operation is more complicated, and the receiving for once having the explosivity of unknown sample to exceed test box
Range, it will cause measurement equipments partially or completely to damage, and cost is very high.It is cheap to be badly in need of a kind of testing cost at present, it is easy to operate
Come the combustibility or explosion property of preliminary test dangerous goods in solid form in vacuum environment with test method easy to spread.
Summary of the invention
Technical problem to be solved by the invention is to provide one kind to test dangerous goods in solid form combustibility in vacuum environment
Or the method for explosion property, it can be used for the burning of dangerous goods in solid form or explosion hazard primary dcreening operation in vacuum environment, surveyed meeting
While examination needs, testing cost is reduced.
The present invention, which adopts 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 packed into polybag；
2) polybag is pierced into at the end of igniting of electronic ignition head and is inserted into sample center, then polybag is put into test block
Test trough in form positioning, connection is placed on the outside of test trough after the power connection end of electronic ignition head is passed through test trough and test block
Infrared remote control igniter；
3) sample, test block, electronic ignition head and infrared remote control igniter are fitted into together in transparent hermetic bag；
4) hermetic bag is evacuated, excites infrared remote control igniter with remote controler, electronic ignition head is made to ignite sample, sees
Examine the phenomenon that sample burns or explodes in vacuum environment.
Test block of the present invention is the cube or cuboid or sphere frame of hollow out, edge be fillet to prevent
Only cut hermetic bag.
The bottom of test block of the present invention is equipped with the test trough for accommodating sample, the side of test trough and test block
Frame be equipped with supplied for electronic igniter head power connection end stretch out hole.
Compared with prior art, the present invention has the advantage that
1) test articles are low in cost.Since test block can be printed out directly with PLA material 3d, cost is about 10
Member；Hermetic bag can be about 5 yuan with commercially available storage vacuum compression bag, cost；Normal domestic use dust catcher can be used by extracting vacuum；It is infrared distant
Controlling igniter and igniter head is commercially available fireworks and firecrackers igniter, and cost is about 60 yuan；No. 54 sections of battery, cost are 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 estimate, more than expected fierce burning or explosion happen occasionally, if directly in expensive vacuum test case into
Row, will cause very big loss.Such as using the method for the present invention, the electricity that general meeting cost depletions of inviolent test of burning are 1 yuan
Sub- igniter head；Burning or slightly violent test of exploding may be damaged the vacuum compression bag that cost is 5 yuan and cost is 10 yuan
Test block；For violent test of burning or explode, can after evacuation by one piece of isolated brick be pressed in IR remote controller and
Among test block, it would be possible to the part isolation of vigorous combustion and explosion, the highest infrared remote control igniter of conservation value occur；I.e.
Make to occur in test beyond expected burning or explosion, all test articles are damaged completely, loss still very little.
2) since the vacuum compression bag using sealing, can also be right if vacuum compression bag does not damage after the completion of test
Dangerous goods in solid form burning or explosion gases are collected, and for measuring and analyzing, assess the risk of gas.
Detailed description of the invention
Fig. 1 is the test block structural schematic diagram used in the method for the present invention.
Specific embodiment
The invention will be further described with reference to the accompanying drawing.
As shown in Figure 1, the test block that the method for the present invention uses is the cube frame structure of a hollow out, or long
Cube or sphere frame structure, edge are fillet to prevent from cutting hermetic bag, and the bottom of test block is equipped with for accommodating sample
Test trough 11, the side of test trough is equipped with hole 12, and the prism of corresponding test block is equipped with hole 13.
The method that the present invention tests dangerous goods in solid form combustibility or explosion property in vacuum environment, concrete operation step
It is:
1) sample is packed into polybag first, to prevent sample dispersion when vacuumizing；
2) sample center is inserted into through polybag in the end of igniting of electronic ignition head, then polybag is put among test block
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 together in transparent hermetic bag；
4) hermetic bag is evacuated, excites infrared remote control igniter with remote controler, electronic ignition head is made to ignite sample, sees
Examine the phenomenon that sample burns or explodes in vacuum environment.
It is the application example of the method for the present invention below, tests the combustibility or explosion of the nitrocotton of 5g under vacuum conditions
Performance:
Nitrocotton 5g after drying is put into the polybag with sealing, in drawing for nitrocotton center insertion electronic ignition head
Fire end.Polybag equipped with nitrocotton is put into the test trough 11 in test block, the power connection end of electronic ignition head passes through test trough
Infrared remote control igniter is connected after corresponding to the hole 13 on prism on 11 hole 12 and test block.By nitrocotton, polybag, electronics point
Duration and degree of heating, infrared remote control igniter and test block are fitted into together in commercially available storage vacuum compression bag, with domestic vacuum cleaners by compressed bag
In air extraction.The position for adjusting high-speed camera, can be observed in test trough by the hollow part of square
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 collecting, and is detected as two
Nitrogen oxide.Test result are as follows: dry nitrocotton, which belongs to from oxygen supply type dangerous goods in solid form, vacuum environment, is ignited rear directly hair
Raw explosion；Experiment generates nitrogen dioxide gas, toxic.
