Car film is almost a must-have beauty item after a new car lands, but there is also a phenomenon of bulging after applying car film, which is the saying blistering, so what is the cause of this? Let's first analyze why it is bulging, and then let's take a look at how to solve it.
The objective element is that the construction process of the film does not pay attention to details, or the craftsmanship is relatively poor, the dust of the window is not thoroughly cleaned, which affects the bonding of the pressure-sensitive adhesive, or the process of pasting does not meet the requirements, as for the quality of the car film has not been affected.
When driving a car in the weather with large air humidity or internal and external temperature differences, it is easy to fog up inside the window, because the exhaled air is more than ten times higher than the water vapor content of the inhaled air, and the ability of the air to carry water molecules is very limited, and the water vapor will pre-condense into liquid water.
The moving car is constantly cooled by cold air due to the resistance of the wind (airflow), and the high humidity air inside the car condenses into water droplets when it comes into contact, which affects the observation of road conditions, and externally, the hot and humid air condenses into water, which is why it fogs up.
The fogging needs to be defogged, otherwise it can not be driven normally, the way to defog is very simple, open the windows on both sides and rely on the cold or hot air of the air conditioner, that is, the front windshield is cooled or heated, dried with airflow, and the temperature difference can be adjusted to solve the fogging problem.
There are no air outlets in the windows and mirrors on both sides, and even if the air outlets and heating are designed, the temperature flowing to the rear of the car will be reduced, and the defogging effect is poor.
Therefore, for these two important positions, electric heating and defogging are used, through high-resistance wires (resistance wires), a large amount of heat energy is generated after being energized, and the ability to condensate is reduced after heating at high temperatures, and at the same time, we can dry condensate droplets through a certain degree of influence.
When the construction does not meet the requirements, turning on the defogging is likely to cause the film to bulge and bubble, prompting the car owners to choose a big brand store for car film!
