[China Glass Network] Is the cause of tempered glass explosion caused by improper use of the consumer or the quality of the glass itself? The relevant data of tempered glass shows that the bursting of tempered glass is caused by the manufacturing process level of tempered glass itself. There are many reasons for rupture of tempered glass, which can be summarized as follows: 1. Influence of glass quality defects: The part of the glass containing stones and impurities is the weak point of the tempered glass, and also the stress concentration. In particular, if the stone is in the tensile stress zone of the tempered glass, it is an important factor leading to the cracking. The stone is present in the glass and has a different coefficient of expansion than the glass body. The stress concentration in the crack region around the stone after the tempering is multiplied. When the coefficient of expansion of the stone is smaller than that of the glass, the tangential stress around the stone is in a tension state. Crack propagation that occurs with stones is highly prone to occur. 2, the surface of the glass due to the addition process or improper operation caused by scratches, blasts, deep explosions and other defects, easy to cause stress concentration or lead to tempered glass self-explosion. From the conclusion, tempered glass itself does have some self-explosive factors, but more reasons are the manufacturing process of tempered glass itself. As a kitchen manufacturer of the first-line brand in China, Fangtai Taili should pay enough attention to these two bursting accidents and try to improve the quality of products to protect the personal safety of consumers.
