Recently, Xiaobian found a lot of small black spots on the car glass, some large and some small, very good-looking. With curiosity, I went to find the use of these small black dots, but what I didn't expect was that these small black dots had a big effect.
Where are the little black dots?
Looking closely, there are so many places with these small black spots. There are small black spots on the edges of the windows, front windshield, and rear windshield.
The large role of small black dots, and the different positions on the vehicle, the role is not the same.
Make the windows more beautiful
First of all, the role of these small black dots is good-looking, the general window and body will have a sealant paste, if only glass can see the traces of those glue, there are these black edge black dots to cover it, the glass looks and the car is integrated, but also more beautiful.
Protects the eyes. Secondly, the coverage area of these small black dots is precisely designed by glass manufacturers and can play a role in blocking the sun's rays. Thus protecting our eyes, we can reduce the damage of sunlight to our eyes, but also reduce the fatigue of driving.
Protective glass. Again, under the strong sunlight of the vehicle, the glass will expand with the increase in the temperature of the metal frame, and because the center of the window is transparent, the temperature rise is not so fast, and the difference in temperature may cause the glass to expand differently and "explode". The small black dot gradually becomes smaller in the middle of the window frame, transitioning the heat and gradually spreading from the outside to the inside, so that the difference in expansion between glass and metal is minimized, thereby avoiding the risk of "explosion".
Prevents refraction at the edges of the glass
Another point is to avoid the formation of light spots on the glass surface after refraction at the edge of the glass, which affects the driver's driving and helps driving safety.
How, do you feel like you're in a posture!!!
