What are the causes of glass breakage?
2 Answers
Glass is formed by melting silicon dioxide and other chemical substances together (the main production raw materials are: soda ash, limestone, quartz). There are 4 main reasons that cause glass breakage: 1. Glass damage leading to breakage: Scratches, surface corrosion, or chipped edges on the glass surface or edges due to careless handling, installation, or maintenance can easily disrupt the stress balance of the glass, triggering spontaneous breakage of tempered glass. 2. Breakage during installation: During the installation process, if the installation gap is too small or the glass directly contacts the frame, the different expansion coefficients of glass and frame under sunlight can generate compressive forces on the edges or corners of the glass, inducing breakage. 3. Breakage caused by glass processing: Glass with drilled holes or cut corners is prone to breakage. 4. Natural environmental factors causing glass breakage: Wind disasters such as strong typhoons can lead to the failure of wind pressure resistance design, resulting in glass breakage.
Last time I went on a road trip, the windshield suddenly cracked, which really startled me. Looking back, there are several common causes: first, external impact, such as a stone hitting the glass at high speed, especially when the vehicle is moving fast, the impact force is greater; second, sudden temperature changes, like parking under the scorching sun in summer and immediately turning on the air conditioning to cool down, causing a significant temperature difference between the inside and outside of the glass, leading to uneven expansion and contraction and stress concentration; third, installation issues, where the new car's glass is poorly sealed or has defects, which may cause spontaneous cracking over time; fourth, inherent defects in the glass itself, such as bubbles or impurities during manufacturing, weakening its strength; fifth, improper maintenance, like using strong acid cleaners that corrode the edges. To prevent this, I recommend regularly checking the condition of the glass, avoiding sudden temperature changes, and maintaining a safe following distance to reduce the chance of stone impacts while driving. If a crack does occur, immediately reduce speed and pull over to the side of the road to handle the situation.
