Hardly possible finds the too small reaction aerogenesis deficiency of inflow, initial analysis exothermic heat of reaction by part it is former should be reacted water enter gas
Capsule causes to react required water deficiency, and because reaction temperature is low when inflow is excessive in addition, aqueous water is small by amount of vaporization, causes to fill
Gas velocity degree slows down, and inflow is advisable in 100ml or so.That is, ensure reaction aerogenesis it is enough in the case of should reduce into
Water, and the inflow in watch is controlled by built-in spring, the air bag heaved after watch is activated can form negative pressure guiding
Water is to flowing in watch.
2nd, pharmacy response is as follows with when experimental result
| Dosages distribution is numbered | Sodium hydroxide weight（g） | Aluminium powder weight（g） | Aluminium wire weight（g） | Environment highest water temperature T 1（℃） | React maximum temperature T2（℃） | Air bag is completely filled with time S（Second） |
| 1 | 9.1 | 6.2 | 0 | 40 | 129 | 4.5 |
| 2 | 9.1 | 4.65 | 1.55 | 38 | 115 | 5 |
| 3 | 9.1 | 3.1 | 3.1 | 31 | 107 | 15 |
| 4 | 9.1 | 1.55 | 4.65 | 28 | 95 | >60 |

（This experiment is 100ml with inflow）Analysis of experimental results：By experimental result it is seen that as aluminium powder matches
Increase reaction it is more violent, the thermal discharge increase of reaction moment, reaction temperature rise, aerogenesis speed is accelerated, by first group and the
It is found that while that aluminium powder proportioning has declined in two groups of contrast tests, but gas production rate is impacted less.Observe in an experiment in addition
More to aluminium powder proportioning, reaction solution boiling is more severe, and reactive material splash is more severe, wherein battery of tests splash is more violent
Strong, intracapsular pressure maintains more than 10KP pressure at the beginning, but over time, the gasbag pressure of first group of experiment
Have a declining tendency, in addition, have liquid water condensation in air bag over time, and the reduction matched with aluminium powder is final
The water condensed out is fewer, this explanation, because the high temperature of reaction causes part is water to be charged air bag, the vapor in air bag
Being cooled to aqueous water by ambient water causes gasbag pressure to reduce.It is worth mentioning that observe air bag pressure again after 5 hours
Power, the few experimental group gasbag pressure of aluminium powder proportioning is high all the better, and initial analysis is due to aluminium powder and the moment of sodium hydroxide reaction
High temperature has not only gasified operative liquid water, and it is that reaction raw materials are reduced also to take away a part of aqueous water and part aluminium powder, and then is led
Gas production is caused to reduce.
Test Summary：A large amount of vapor are entered in fact in the early stage that air bag is inflated, and lifesaving will not so be produced
Raw unfavorable factor, it is important to need after pressure reduces under water vapor condensation, it is necessary to the pressure for having hydrogen is supplemented, so in order to
Reaction is unlikely to excessively acutely, and needs pressure supplement just to need to add certain aluminium wire after later stage water vapor condensation, and he will not
Reacted away in the very first time, moreover it is possible to pressure is supplemented when packing pressure reduces, so both having ensured that gas production rate will also ensure
The proportioning of aluminium powder, second group of dosages distribution is optimal in five groups at last in several groups of contrast tests more than.
