When it comes to glass thermal cracking, many people may think that it will break because of the temperature rise, so this phenomenon may occur easily in temperate and tropical places. This is a misunderstanding that most of the hot burst of glass occurs on sunny days in winter, where it freezes in the cold weather in the morning. This is because too low a temperature and heat generated by sunlight cause a temperature difference in the plane direction of a piece of glass, which forms a thermal shock and thermally bursts.

Therefore, the heat absorption rate also changes when the meteorological conditions change. Since the heat absorption rate is lower, the shielding coefficient becomes smaller, and the cold air load can be alleviated, so that the heat absorbing glass used in the temperate zone and the tropics where the temperature does not fall is less likely to be thermally cracked, thus allowing the heat absorption rate to be increased. In the day rolling, it is also possible to use a glass having a high heat absorption rate which has been reinforced by deep color. Jinhua fire glass customization
Glass hot cracking
From the beginning of the use of the heat absorbing glass, the phenomenon of cracking due to the heat of the glass continues to occur. At the same time, it was found that the glass was broken due to the same reason. Not only do these glasses burst hot, but they can be used in a variety of architectural glass used in construction if not used properly.
There is only one point to prevent this kind of phenomenon, that is, "do not create excessive temperature difference on the surface of the same glass." If Wenzhou fireproof glass manufacturers do not produce a temperature difference, there will be no thermal stress, so it is impossible to cause thermal cracking. As for the measures, the first consideration is to manufacture glass that can withstand this temperature change. This glass is present.
For example, when there is a large temperature difference, the glass with a small thermal stress inside it (such as borosilicate glass) falls into this category, but because of its special composition, it is expensive, such as quenching. It is also tempered; it is also very good, but the wired glass can not be tempered like tempered glass: there is also the problem of increasing the strength of the edge of the glass. Because it does not know how to use Wenzhou fireproof glass manufacturers, it is practical. It is also not easy to achieve. As a result, there are no other suitable solutions other than in the design, construction, and use stages to prevent thermal cracking.
