12 1 1 specific gravity of extinguishing agent

There is a fire extinguisher. F 1 Regulations stipulate that all racing cars must be equipped with fire extinguishers.

All racing cars must be equipped with extremely complicated remote fire extinguishers, which will automatically turn on once the engine catches fire. There are many kinds of fire extinguishers, and the understanding of installing fire extinguishers is the same, but there are different views on what kind of fire extinguishers to install. Take the most common dry powder fire extinguisher as an example. First of all, in view of the amazing speed of F 1 racing car, the two kilograms of dry powder that a general fire extinguisher can hold is simply not enough; Secondly, a dry powder (sodium bicarbonate, etc. Corrosion of the car itself will also have a bad influence on the throttle of the car. At present, the F 1 racing car uses the Shuicheng foam extinguisher. This fire extinguisher can release 95% of the extinguishing agent within 30 seconds, which is in line with the regulations of the International Automobile Federation. When the extinguishing agent is released, it will form a film covering the high-temperature oil and gas to prevent it from overflowing and burning on the surface of gasoline. On the one hand, this extinguishing agent suffocates the fire by isolating oxygen; On the other hand, the water contained in the foam will also play a role in cooling down-the effect is obvious, but the cost is higher.

At present, the fire extinguishing device cost of an F 1 racing car is 6 100 Euro.
