Nitrogen accumulator airbag life

How do airbags produce nitrogen gas?

Today’s airbags use a different chemical to produce nitrogen gas: guanidinium nitrate, plus a copper nitrate oxidizer. When ignited, guanidinium nitrate decomposes into nitrogen gas, water, and carbon. The copper nitrate oxidizer reduces the temperature of the exhaust gas, according to Blomquist.

Does Nan 3 / Kno 3 airbag gas prevent azide exposure?

Therefore, the use of 62.5/37.5 (NaN 3 /KNO 3) will prevent the occupant from toxic azide exposure to the inflation of airbag. The onset temperatures to exothermicity of different weight compositions of NaN 3 /KNO 3 airbag gas generants vary from 381 °C to 412 °C for different weight compositions studied.

How to achieve complete combustion of airbag gas generants?

The selection of a suitable oxidizer in right proportion with fuel plays a major role in attaining complete combustion of airbag gas generants in automobiles and this type of research in which varying the fuel/oxidizer ratio to obtain complete combustion of airbag gas generants have not been addressed before to the best of our knowledge.

Can I Use Nan 3 as a fuel in my airbag inflator?

9. N/A - Not available. NaN 3 is conventionally used as a fuel in the airbag inflators due to its ability to produce the pure nitrogen gas within a short span of time.

Is guanidinium nitrate good for airbags?

He says this formulation has other positives: guanidinium nitrate is relatively inexpensive and, unlike ammonium nitrate, is not particularly moisture sensitive. Guanidinium nitrate is now the chemical of choice in airbags. Chemical systems are no longer the only technology used to inflate airbags.

How airbag system is activated?

Based on the seriousness of the impact, the airbag system may be activated. Than an inflation module initiates gas generation by initiators (with its thermal resistance) , which fills the airbag cushion itself . Under normal operating conditions, initially all of them are take place inside the housing.
