Description
Technical field
The present invention relates to a kind of gas producing medicinal, more particularly to a kind of gas production is big, combustion temperature is low, safe and reliable, inexpensive, combustion
The gas producing medicinal of gas cleaning.
Background technology
Gas-forming agent is mainly by fuel agent, oxidant and additive composition.Additive generally comprises catalyst, bonding
Agent, cooling agent, burning ratemodifier etc., can be by gas generator, and rapid burning discharges a large amount of gases, for externally doing work or filling
Gas buffers.Gas-forming agent is widely used in military and civil area.The former is such as the rail control engine energy, landing cushion gasbag
Source of the gas etc.；The latter such as civil aviaton meets an urgent need slide source of the gas, Mae West source of the gas, unmanned plane buffering landing air bag, underwater salvage air bag
Deng.
At present, gas-forming agent is broadly divided into nitrine class and non-nitrine class gas-forming agent.In nitrine class gas-forming agent
Azide is fuel agent, wherein Alkali-Metal Na NO3The most used, oxidant typically uses metal oxide Fe2O3、MnO2
Deng.Composition of Sodium Azide Gas Generant tool ignition temperature is low（About 1500K）, a large amount of nontoxic nitrogen, burning speed are produced after burning
Spend the advantage such as relatively fast and free from the influence of the external environment.But azide is easily production after toxic articles, with oxidant reaction
Raw stimulating component, residue is not easy to filter after burning；The danger such as blast during use be present.Therefore function admirable is developed,
Safe and reliable non-nitrine class gas-forming agent is imperative.
The content of the invention
In view of the shortcomings of the prior art, object of the present invention is to provide gas production is big, combustion temperature is low, safe and reliable, low
Cost, the gas producing medicinal of combustion gas cleaning.
Technical scheme includes potassium hyperchlorate and azodicarbonamide, its mass percent component：
Potassium hyperchlorate：40%~60%
Azodicarbonamide：40%~60%.
Preferred mass percentage component of the present invention：
Potassium hyperchlorate：43%~47%
Azodicarbonamide：53%~57%.
Potassium hyperchlorate of the present invention is oxidant, and granularity is no more than 150um.
Azodicarbonamide of the present invention is reducing agent, and granularity is no more than 20um.
Compared with prior art, gas producing medicinal of the present invention has the characteristics that gas production is big, combustion temperature is low, gas componant is clean；
It is cheap and raw material are easy to obtain, production process safety, it can be widely applied to civilian and military domain.The present invention's has
Benefit has the technical effect that：
（1）Gas production is big：More than 600L/kg（Standard state）.
（2）Safety and stability：Sensitivity is low.
（3）Cost is low：Azodicarbonamide source is wide, cheap.
（4）Combustion gas is cleaned：Main component is H2、CO2、N2、H2O etc..
