Abstract
The utility model discloses a firework and cracker medicament 75 DEG C thermal stability performance tester; the utility model changes prior oven detection device which uses air as heat transferring medium and makes use of water as heat transfer medium for water solution device; the utility model is characterized in that a plurality of test tube canisters are arranged on a cover plate and test tube holes are arranged on the test tube canisters; thus, experiment reagent is reduced; experiment is safe and time-saving and experiments can be carried out for a plurality of to dozens of reagents; work efficiency of experiment is greatly improved and the utility model is the optimal device for thermal stability performance testing.
Description
Technical field: the utility model relates to a kind of fireworks and firecrackers medicament thermostability test unit, particularly relates to 75 ℃ of thermostability test units of a kind of fireworks and firecrackers medicament.
Background technology: fireworks and firecrackers is a kind of inflammable and explosive object, 75 ℃ of thermostabilities are to weigh one of important indicator of fireworks and firecrackers medicament heat sensitivity size, its test mainly is to be used for judging that whether firework medicament is to hot destabilization, be subjected under the examination state transportation whether dangerous, and whether use safety, at devices such as existing use self-control safety type baking oven and automatic control thermometrics, it is to utilize air to make heat conductor, the using gases heat transfer theory, its test unit is a baking oven, can only do simultaneously two medicaments at most and detect, big general minimum 50 grams of wanting of dosage are gone up 100 grams at most, in case blast, its explosive force is big, easily causes casualty accident, and safety coefficient is little; Test, the sample preparation time is long, inefficiency, and generally soon 48 hours, the longlyest want 144 hours, the instrument and equipment utilization factor is low, and equipment investment is big.
The utility model content: the purpose of this utility model will provide the water-soluble pot of a kind of use to test exactly; The test dosage is little, safety coefficient is big, and test period is short, high efficiency, and the capacity utilization height is invested 75 ℃ of thermostability test units of little fireworks and firecrackers medicament.
The technical solution of the utility model is achieved like this, and it comprises casing, cover plate, dividing plate, heat-generating pipe, heat-insulation layer etc., is provided with altitude valve on casing, and water level gauge, humidostat on the cover board are provided with the test tube tube, and dividing plate is located at the top of heat-generating pipe.
On the cover board be provided with 1-50 and prop up the test tube tube, have the test tube aperture around the test tube tube, test tube tube underrun dowel interconnects each test tube tube fixing.
On dividing plate, have the dividing plate aperture.
The sealing of stopper jam-pack is used in the outlet of test tube tube during test.
The utility model is owing to adopt such scheme, make it have following advantage: dosage is very little during test, be generally about 10 grams, safety coefficient when having improved operation greatly, test time spent, sample preparation time spent weak point, high efficiency adopts the water-soluble pot of this kind constant temperature form to detect, the use baking oven form that is better than greatly using always detects, and equipment investment is 75 ℃ of thermostability tests of fireworks and firecrackers medicament optimum device for a short time.
Description of drawings: Fig. 1, be the utility model structural representation.
Among the figure: 1, casing, 2, cover plate, 3, stopper, 4, the test tube aperture, 5, dowel, 6, dividing plate, 7, heat-generating pipe, 8, heat-insulation layer, 9, altitude valve, 10, water level gauge, 11, humidostat, 12, the test tube tube, 13, the dividing plate aperture.
Embodiment: as shown in Figure 1,75 ℃ of thermostability test units of fireworks and firecrackers medicament, the casing ectonexine uses stainless steel material to make, interlayer is provided with heat-insulation layer 8 insulations, on casing 1, be provided with altitude valve 9, water level gauge 10, humidostat 11, before on-test, water filling in casing 1 is by water level gauge 10 control amount of water, put to adding water level, then the cover plate 2 that has 48 test tube tubes 12 is covered the casing 1 that is filled with water, the test tube that medicament is housed is put into the bottom with the test tube tube 12 that dowel 5 connects, around test tube tube 12, have test tube aperture 4, so that water flows into, make in vitro that medicament is subjected to gesture even, use stopper 3 stoppered test tube tubes 12 then, the test tube tube 12 that has dowel 5 is placed on the dividing plate 6, regulate humidostat 11, water by in the heat-generating pipe 7 heating water tank bodies 1 can detect test article, detects after finishing promptly by altitude valve 9 and bleeds off water in the casing 1.On dividing plate 6, establish dividing plate aperture 13, purpose is that the water of being convenient in the casing 1 flows freely, water is heated evenly, its detection speed is fast, former test unit once can only be made one to two sample, and adopt this device once can finish nearly 48 samples, equipment investment is minimum, is the optimum device that test detects.
