What are the disadvantages of car exposure?

1, the main impact of vehicle exposure is the generation of harmful gases. Most of the materials in the car are plastic or leather products. Long-term contact will produce harmful substances such as formaldehyde. If you enter the car and turn on the air conditioner directly without opening the window, then harmful gases will be inhaled into people's bodies, causing harm to people's health.

2. Exposure has a great influence on the body interior, paint and tires, which affects the service life of the whole vehicle. It is best to avoid exposure to the sun. The car has been exposed to the sun for a long time, and we will have a pungent smell as soon as we open the door.

This is the plastic smell of automobile interior heated by the sun, and the ultraviolet rays in the sun can easily lead to the aging of automobile plastic parts. In particular, the sealing ring of the window is exposed to the sun for a long time, which is easy to age and crack, so the sealing performance of the window will be reduced, and water leakage and seepage may occur.

3. The temperature of vehicle glass rises sharply after exposure, and its physical properties will change. If the temperature is very high after exposure, washing with cold water is very easy to cause the glass to burst or damage its performance.

4. Vehicle exposure may lead to vehicle spontaneous combustion. This is definitely not an alarmist. As a matter of fact, the news has reported many auto-ignition incidents. Because of the current climate change and other reasons. The highest temperature is getting higher and higher. The temperature of a car exposed to sunlight will only be higher than the ambient temperature. So spontaneous combustion is also possible.

Some people drive in a hurry. Turn on the air conditioner directly after getting on the bus. Sit in your seat. This can easily lead to the onset of hemorrhoids. There will be a lot of pustules on your ass. Traditional Chinese medicine is used to calling it heat toxin.

6. Exposure may lead to aging of automobile lines, which in turn may lead to loosening and falling off? Danger! Exposure to the sun will also make the sealing of the car worse, and the rubber strip at the sealing will be loose! ?

Extended data:

Tire pressure rise

When heat expands and contracts, the tire pressure will become higher, increasing the risk of tire puncture when driving. Many friends know this, so the air pressure will be lower in summer.

In summer, the tire pressure should be reduced by 0.07 on the normal basis. Basically, if the outdoor temperature changes by 6℃, it is equivalent to our usual tire pressure increasing or decreasing by 0.07.

That is to say, our standard tire pressure is, for example, 2.5, so it is so cold in the morning and so hot at noon, and there is a lot of difference between 24℃, right? For example, it's over ten degrees in the morning and super hot at noon, 36, 37 and 38℃, so the difference is about 24℃.

Excessive tire pressure will affect the braking force of the car and increase the risk of puncture. This is 0.07×4, which means 2.5 tire pressure plus 0.28, and then 2.78. This tire pressure is relatively high.

Well, if we are only going on a business trip at noon and driving at a high speed, this 2.78, because the car is driving fast, the gas in the tire will further expand and the tire pressure may be higher, then the braking force and the risk of tire puncture will be affected to some extent.

Affect car paint, different components, temperature resistance is also different. The most common primer is epoxy resin, and its temperature tolerance in air is at least above 120℃, that is, if you throw this raw egg on the hood of this engine, it will become a poached egg, and it will still not hurt the car paint.

The ultraviolet rays in the sun lead to the aging of car paint, so the damage of this solar temperature to our car paint is not as great as we thought, but the damage of this temperature is not great. This kind of ultraviolet light in the sun will have an effect on the organic components of the resin in the paint, accelerating the aging, but it still has an impact.
