In order to be able to bear the weight of 1 ton or even 4 tons, most tires are filled with compressed air, which can withstand greater pressure in the same volume. Therefore, the experience drivers generally warn newer not to pull out the air nozzle casually, because it is very likely that when the air nozzle is pulled out, high-pressure air will be sprayed on the face with the air nozzle and cause injury.
Summer is coming soon, and car owners can release the compressed air from the tires. Adding nitrogen, although more expensive, has two major advantages.
Ensure driving safety
As we all know, nitrogen is an inert gas. When a car is running at a high speed, nitrogen will not expand as the temperature of the tire rises, causing a tire burst and causing a traffic accident.
Reduce tire noise
Compared with compressed air, nitrogen gas will greatly reduce tire noise.
Of course, there is tire pressure that affects driving safety. Many models will mark the normal tire pressure of the body in the corresponding position. It is recommended to make measurements frequently, and when the pressure is low, it is best to add nitrogen as much as possible. If not, then directly fill with air. You can continue to use it normally until the next nitrogen is found. Here are some explosions. Common sense of fetus.
From the definition of explosion, there are three forms: physical explosion, chemical explosion, and nuclear explosion. Among them, tire blowouts account for two types of blowouts, physical properties and chemical properties.
The tire’s external structure is damaged by the contact of the external force. In addition, the tire is filled with oxygen-containing (combustible) air for a long time, which causes the tire to expand and contract during the summer when the tire is heated, causing the cord fabric in the tire to be exposed to oxygen. The oxidation reaction destroys the compressive strength of the tire itself, and the resulting puncture is called a physical puncture.
Because the tires are filled with air, the vehicle runs at high speed for a long time in summer, and the tires work in a high-speed, high-pressure, and high-heat environment. When the rubber is heated, it releases alkane flammable gas, which ignites the combustion-supporting oxygen-containing component air, which causes a puncture. Spontaneous combustion with tires is a chemical puncture.
