Why does condensation appear on the inner surface of the car tarpaulin

Although the use of car tarpaulin can provide protection to the outer layer of the car, it also has some defects in its use. For example, condensation water often appears on its inner surface. Car owners who pay attention will find this phenomenon occurs more frequently in the hot summer. The condensed water will not only soak the paint film on the surface of the car, but also soak the materials of the car tarpaulin, which is not conducive to their long-term use. So, why does condensate appear on the inner surface of the car tarpaulin? Let's analyze it carefully.

Although the car tarpaulin and the car surface are close together, there is still a certain gap between them, and there is also a certain amount of air in between. In the hot summer, the temperature of the outer surface of the car tarpaulin will gradually rise after being exposed to light, and then the temperature of the air inside will rise. When it reaches a certain temperature, the temperature will stabilize. The outside air will form a flow of air, and when it blows over the outer surface of the car tarp, it will take away a part of the heat, so that the temperature of the inner air will be higher than the temperature of the outer air, and the air on the side with the lower temperature will be lost. The heat condenses into water droplets and then adheres to the inner surface of the car tarpaulin to form condensed water.

When using the car tarpaulin daily, pay attention to make the tarpaulin tighter, so that there are not too many gaps between it and the surface of the car, which can greatly reduce the chance of condensation water, so as to better use it.
