On June 25, 2016, near the Changlinggang Service Area in Hong'an County, Wuma Expressway, a rear tire of a semi-trailer loaded with 21 brand-new cars caught fire, causing fires in the cars and the mass-cars on board, resulting in the burning of 17 new vehicles. .

misunderstanding

Many people think that the cause of tire fire is mainly due to the tire being affected by the high temperature environment, which in turn leads to fire burning. Is the tire fire really because of the high temperature?

Many people think that tires are flammable. In fact, this view is wrong. Flammable substances are flammable substances with a burning point below 28 degrees, such as white phosphorus. The ignition point of rubber is 350 degrees or more. It can be seen that once this tire reaches this temperature, it will burn with the presence of oxygen.

Driving in summer, especially large trucks, produces a large amount of heat for a long period of time under conditions of high temperature, friction, emergency braking and dragging. Burning occurs when the tire reaches its ignition point. Usually car tires don't happen like this.

The rear tire caught fire, causing the car and the mass car

note

Tires can only be regarded as combustibles, and there must be an open fire. It usually takes a long time to light (conditional can try it). Many times the car caught fire during the driving process, mainly due to friction brake pads producing high temperatures, and sometimes due to the effect of gasoline. The fire at the warehouse of the warehouse was basically caused by an open fire. Therefore, the places where the tires were stored were all open flames.

Once a tire fires, it is difficult to extinguish and appropriate fire extinguishing methods should be taken. Especially when car tyres catch fire during driving, remember not to pour with water.

Extinguishers should be covered with fire extinguishers or sand. In the summer high temperature environment, after driving continuously for more than 4 hours, the driver is best to rest in the shade, so that the tires and the body naturally cool, you can also use the cold water to wipe the wheel indirectly to cool the tires. Remember not to splash water directly to cool the tire because it will also accelerate the aging of the tire!

Why is it less prosperous to splash water on a fired tire?

After the car tires catch fire, the rubber on the tires will burn even thinner, and the rubber will not withstand the tire pressure after it melts. If the water is splashed with cold water, it will lead to abnormal aging of the tire rubber and even cause the ply to fall off. The fire-thaw rubber will float on the surface of the water and continue to burn because the density is lower than that of water. At the same time, great pressure may also occur. Thinned tires broke. In addition, pouring cold water on the tires can still cause tire explosion.
