What are the causes of car glass breakage?
1 Answers
Car glass breakage can be attributed to the following reasons: 1. Poor tempering process: Tempered glass inherently has a self-explosion rate of about 0.3% due to quality issues, which strictly speaking indicates a problem with the glass quality. 2. Uneven stress distribution: If the glass is installed without leaving sufficient edge clearance, it may expand when heated and press against the metal frame, leading to uneven stress distribution and ultimately causing the glass to crack. 3. Deformation: During the process of applying window film, if the glass is not heated evenly and a heat gun is used to shape the film, localized heating can cause uneven thermal expansion stress and deformation, resulting in glass breakage.
