By homogenizing tempered glass (using the second heat treatment process), the self explosion rate of tempered glass can be greatly reduced. The national standard for homogenized tempered glass aims to specify the performance, homogenization treatment process, system requirements, and inspection methods of homogenized tempered glass. This standard has recently passed an expert review meeting in Beijing, organized by the National Technical Committee for Standardization of Building Glass.
Tempered glass, as a type of safety glass, is widely used in construction and other fields. Two witnessed drivers at the scene said that they often commute between Ergezhai and eight kilometers, which is too bad. They drive carefully and dare not be careless. However, traffic accidents with tempered glass still occur from time to time. However, the self explosion problem of tempered glass limits its application. After long-term research, experts have found that the presence of NiS stones inside the glass is the main reason for the self explosion of tempered glass. So what kind of glass can truly be considered heat-resistant glass?
At present, there is no clear standard definition for tempered glass in China. However, countries such as Japan have long had specific regulations regarding this, which require the material to be borosilicate glass, microcrystalline glass, or aluminosilicate glass, and also have clear regulations on the coefficient of expansion. The reporter saw on the accident section that the road was pitted and pitted, with a large mud pit in the middle. Vehicles passing through this area are prone to accidents such as overturning. In the middle of the road, which is 3 meters away from the accident section, there are two "road traps" with large openings, the covers have disappeared, and there are no street lights on both sides of the road. The situation of driving at night is even more serious.
There are also differences in the scope of use, such as for open flames, ovens, microwaves, etc. Professor Shi Xinyong, who has been engaged in glass research on tempered glass, suggests.
