Car wash at high temperature is easy to cause glass burst, do not use cold water directly

[China Glass Network] In such a high temperature of 40 ° C, many car owners want to give the car a cold, but there are many hidden dangers when you wash your car. When a car owner gave himself a car wash last week, the front windshield of the car broke open inexplicably.

The car owner's car wash process has nothing special, that is, the car is wet, foamed, then rinsed with cold water, then wiped dry with a cloth. But after a while, the windshield split directly from the outer layer. The dealer 4S shop does not give the warranty, and the insurance company does not give the claim. After the investigation, it may be that there is fine sand on the front windshield, which will lead to cracking.

On this question, the reporter asked Xu Zhigang, the technical director of Shanghai Volkswagen Zhejiang Aozhong 4S shop. He analyzed three points. "It is now three days, the temperature is high, the car suddenly encounters cold water under high temperature exposure, and the thermal expansion and contraction window Glass will burst. In addition, most of the window glass is now filmed, because the shrinkage ratio of film and glass is different, glass burst will occur when washing at high temperature. Also, the window glass is impacted with small cracks. Or a small pit, so washing the car at high temperatures, it is easy to cause the glass to burst."

Therefore, he reminded the majority of car owners that the car will be exposed to high temperatures, the temperature will rise, or after the long-distance long-distance driving, do not take the car to wash, first stop and let the car cool down and then wash the car. There is also a car wash shop owner, you can move the water tank to the sun in the summer when washing the car, do not rinse directly with cold water, or touch the car glass to touch the car to see if the temperature is too high, then wash the car.

The person in charge of China Pacific Zhejiang Branch said that only the glass can be broken separately to get claims. However, in some cases, such as loss of sunroof glass, loss of imported glass according to domestic insured price, loss of glass breakage during repair, loss of glass film, loss of identification, loss of additional equipment, etc., no claims are made.

Among them, the majority of car owners should pay attention to the fact that malicious behavior is not within the scope of claims. Even if the glass is damaged separately, but the window is maliciously damaged, this is a malicious act. It is a criminal case. If it is not owned by the insurance company, it must be reported to the public security department.
