What are the causes of spontaneous car glass breakage?
1 Answers
The causes of spontaneous car glass breakage are as follows: 1. Poor tempering treatment of the glass itself, which strictly speaking indicates a quality issue with the glass. 2. Additionally, during window tinting, if the glass is not heated evenly and a hairdryer is used to shape the film, localized heating can cause thermal expansion stress deformation, leading to glass breakage. This situation arises because many tinting practitioners in the current market lack proper qualifications and do not fully understand the underlying physical phenomena. 3. When there is excessive temperature variation in the window film, stress deformation can also occur, causing the glass to break. This scenario highlights the film quality issues that manufacturers often emphasize. Although these three situations are the main causes of spontaneous glass breakage and the phenomena are clear, window tinting is a complex automotive decoration process, and sometimes even applying the film twice can result in breakage. Precautions for car window tinting: 1. Always use high-quality film and choose a 4S shop for installation, so you can claim compensation if any issues arise. 2. If you opt for an external shop, it's best to supervise the process and instruct the workers to avoid using hairdryers and not to scrape the rear window too dry. 3. On rainy days or in the morning, if you notice fog or condensation on the rear window, avoid wiping it with a hot towel, as this can also cause breakage. The correct approach is to turn on the defroster or use the rear wiper.
