With the development of science and technology, various products have been applied to our lives. In automobile lights, car light waterproof and breathable film is one of them. A sort of.
Every time after a typhoon or heavy rain, it rains, rains, rains every day. If you are careful, you may sometimes find that There is actually a layer of fog inside the headlights of your car. To exaggerate a bit, it looks like a fish tank filled with water. You can even keep a small fish in it! So where does the water come from?
The headlight is indeed designed to be waterproof, but it is not completely sealed. Behind the light, there is also a specially designed vent pipe or vent hole. to dissipate heat from the car lights. Since the lamp is ventilated, water vapor in the air can also enter the lamp together with the air. After encountering cold and condensation, the water mist remains in the lamp.
The waterproof and breathable membrane for car lights produced has extremely tight mesh micropores, with a pore size of about one-twentieth-thousandth of a water droplet. , can block tiny water droplets and dirt particles as small as 0.1 micron in size, ensuring that the car lights will not be affected by foreign matter.
In addition, these micropores, which are 700 times larger than air molecules, ensure that the product can achieve reliable air permeability and pressure balance. Its proprietary microporous breathable membrane Allows air and gases to pass through freely, so moisture can diffuse away before condensation problems occur.
So, no matter it is windy, rainy, or dusty, the waterproof and breathable film for car lights can ensure that liquids and foreign objects are not Breaking through the tiny scale of 1 micron. At the same time, no matter how significant the temperature difference between the inside and outside is, the waterproof and breathable membrane can diffuse well, allowing water vapor to diffuse out of the headlights smoothly.
