Will 40℃ exposure really damage the car?

Hot summer comes quietly, especially in big cities such as the south. Under the scorching sun at noon, the surface temperature of the car will definitely exceed 40 degrees. Many friends will worry about whether the car will be damaged under such exposure. Faced with these bad weather, many objects can't stand the exposure of the sun.

As a mechanical product, although the car is made of steel, it will inevitably be mixed with plastic materials. There is good reason to worry, but you can rest assured that car paint, glasses, interiors and tires are usually exposed to the sun directly, but that doesn't mean they will get sunburned. Car paint can withstand the high temperature of 140℃, but this does not mean that it can be exposed to high temperature indefinitely without damage. Tire rubber is still very sensitive to ultraviolet radiation. Under ultraviolet irradiation, rubber will be photoactivated and trigger a chain oxidation reaction. Therefore, it is usually necessary to add stabilizers and protectants to tire rubber to prevent photooxidation, but stabilizers also have a certain protection period. Once this period is exceeded, rubber will become brittle and crack.

In addition, although tire rubber has a high-temperature resistant formula, the high temperature of asphalt pavement in hot weather will also lead to rubber softening, and the same problem also exists in rubber products such as windows, skylights and wipers. The headlights of cars are made of polycarbonate, while the interior is made of plastic and slush molding technology. After a long period of direct sunlight, plastics will age and become brittle. Therefore, the plastics of automobile interior also need stabilizers, but when the stabilizers and protectants fail for a long time at high temperature, the plastics will also age, leading to yellowing of headlights and brittleness of interior. Exposing the car to the sun will affect the acoustic effect of the car. No matter how good the car stereo is, there is no doubt that not all speaker materials can resist drastic temperature changes.

Especially the car bass unit, after the speaker is aged, the bass will be distorted and even produce * * * sound. There are two factors that affect the life of car stereo, one is loud volume, and the other is sun exposure. You can put the rear of the car in the sun for two days to see if the bass effect of the car has changed. Generally, the car will not be directly damaged by the sun. Because the plastic of the car interior is specially treated, if the car is exposed to high temperature, the highest temperature in the car can reach 80-90℃! Car owners often put shading mats on the dashboard to protect the dashboard after paving. In addition, the sunshade mat also has a certain heat insulation and cooling function, and it has a certain energy-saving function after installation, which is why many car owners take a fancy to it.

If the automobile engine is used for a long time, the rubber tube and other parts will become hard at high temperature. Once the oil leaks, it may cause the engine to spontaneously ignite at high temperature. If the car's carbon tank is blocked and the fuel tank is overfilled, gasoline will overflow at high temperature, and engine parts that encounter open flame or high temperature may also cause spontaneous combustion. In the face of high temperature, it can be protected by physical protection, such as cars and clothes. If you really don't want to spend money, you can also put a sunshade net blue in the trunk and take it out at any time, which is more convenient and can be checked directly, so it is not easy to fall on the car surface. However, it is necessary to remind everyone that the license plate should be displayed.

At the same time, don't put inflammable and explosive articles in the car. These substances burn easily after being exposed to the sun, which will seriously damage the car. You can also use the rear of the car to protect yourself from the sun. In fact, the car is exposed to the sun, because the air inside the car is not circulating. It is very likely that the temperature inside the car will be higher than that outside the car. And if you sit directly in the car, it will be very uncomfortable. Not only will the air stink, but it will also affect the mood when driving. Some people say that buying a sun-proof car coat can really play the role of sun protection, just stop for a while, but it is too troublesome to use it every day.

Old drivers like to prepare a parasol for getting on the bus and put a parasol for the car at the front windshield. Even if the effect is not very good, it can come in handy. In addition, in hot summer and hot weather, we must pay more attention to car maintenance.
