Airbag Car

Although Airbag with the name "The airbagWe know, but basically what caused the opening Airbag It may not be the air we breathe at all and it is a series of chemical reactions that cause bloating Airbag will be.

Most of us think that an explosion is a very scary event, but that is not always the case!. Every day explosions save people's lives! If you ever have an accident, with a controlled explosion, an airbag will pop out from inside the dashboard and take the impact caused by Accident, reduces the damage to your body. mechanism Air bag performance Very simple but smart.

Of course, in the first ideas that half a century ago for Airbag It was proposed to use compressed air, but the big problem of using compressed air is the storage of compressed air for a long time, because a source of compressed air cannot keep compressed air forever, and it needs to be recharged frequently so that it can act on time when necessary, and this problem also requires a charging system. car creates that is not a good idea.

In contrast, however Automobile manufacturers They were looking for better solutions and finally chemical engineers in cooperation with engineers automotive industry They were able to find the final solution; Using a substance that can produce a lot of gas when burning so that this gas can be used to inflate Airbag used.

Chemicals generally produce gas when they burn and increase in volume, and it may seem like an easy solution to the problem, but not every chemical can be used for this purpose.. The material used for the airbag must first burn at a very high speed in order to produce a large volume of gas in a fraction of a second..

In addition, the produced gas should not be toxic, and the produced gas should not be too hot, as it may cause burns. Airbag which is made of nylon and will eventually harm the driver and passengers. Considering all this, different materials are used for this purpose Test placed until finally Automobile manufacturers were able to combine magic NaN3 or, as it is more commonly called, to obtain sodium azide, a compound now widely used in airbags is used.

This material burns quickly when exposed to a flame, and the result of its burning, which is at a temperature of about 300 degrees, is a significant volume of N2 or nitrogen gas, and it is exactly this gas that is released that fills the air bag.. All these events are done in less than a hundredth of a second.
