Spontaneous self-explosion of tempered glass is troubling numerous home decoration and construction projects. The core causes can be broadly categorized into three main types.
One is Internal impurities First, nickel sulfide crystals mixed into the glass raw materials expand in volume when exposed to temperature changes, generating internal stress that leads to spontaneous cracking; second, ... Processing defects The edges of the glass are not precisely ground and chamfered, and microcracks are present, leading to stress concentration and fracture.
Third is Improper installation The glass edges were squeezed, the screws were tightened too tightly, and expansion joints were not预留, leading to excessive external stress.
Targeted prevention and control measures must focus on three key points: First, use homogeneous-treated tempered glass to eliminate impurity risks at the source; second, verify 3C certification to ensure that edge finishing in the processing stage meets the required standards.
During installation, use glass pads for cushioning and leave a 5mm expansion joint to prevent rigid contact. By mastering the key prevention and control measures, you can significantly reduce the risk of spontaneous breakage in tempered glass.
