The front windshield glass of a car is the largest glass on the car body. It can be used to block wind and rain, and it can also resist the splash of some flying rocks, gravel and some foreign objects to protect the safety of drivers and passengers. There have been cases where car glass exploded spontaneously, so many car owners are worried that the front windshield of the car will break on its own?
In fact, the front windshield may indeed spontaneously crack, but generally the front windshield is laminated glass, with a multilayer organic polymer film sandwiched between two or more pieces of glass, which increases the glass’s ability to resist breaking. , So don’t worry too much. However, self-fracture will cause a certain obstacle to the line of sight, and will affect the driving. What is the cause of the car's windshield spontaneously cracked?
Auto windshield self-cracking generally occurs at the edge of the glass. The main reason is that the laminated glass is heated and then cooled during the processing of the laminated glass, and the glass will generate internal tensile stress and surface compressive stress. The two forces are stable when they are in a balanced state. Otherwise, self-rupture will occur.
In addition, after the car glass is exposed to the sun, if it encounters cold water, the cold and heat variables are too large, it may also cause the glass to burst. If the front windshield is spontaneously cracked, you should pull over and stop immediately and do not continue driving. Although some small cracks can be repaired, it is recommended to replace it directly for safety reasons.
