The safety of semi-tempered glass is superior to that of ordinary glass to some extent, but it is not absolutely safe in all aspects. Below is a detailed comparison of the safety of the two.
Strength
The strength of semi-tempered glass is more than twice that of annealed glass, which also means it has higher strength than ordinary glass. Therefore, when subjected to external impact, semi-tempered glass is less likely to break.
Fracture characteristics
Ordinary glass forms sharp shards when broken, which can easily cause injury. In contrast, while semi-tempered glass forms large shards and radial cracks when broken, most shards do not have sharp edges, which relatively reduces the risk of direct injury. However, these shards can still cause harm, especially when the human body collides with them.
Thermal stability
The thermal stability of semi-tempered glass is significantly better than that of ordinary glass. After semi-tempering, the glass can withstand a temperature difference of about 75°C, while ordinary glass is prone to thermal stress and breakage due to uneven internal stress distribution when exposed to high or low temperatures. Therefore, in environments with significant temperature changes, semi-tempered glass is safer.
Self-explosion
Semi-tempered glass does not self-explode, which is an advantage over tempered glass. Although tempered glass has higher strength and better safety, it carries the risk of self-explosion, which somewhat reduces its safety.
Application scenarios
Due to the potential for injury from shards formed by broken semi-tempered glass, it cannot be used in skylights or situations where human impact may occur. In these scenarios, it is necessary to choose safer tempered glass or other safety glass that forms granular shards upon breaking.
In summary, semi-tempered glass has higher safety in terms of strength, thermal stability, and self-explosion compared to ordinary glass. However, its safety is somewhat limited in terms of fracture characteristics and application scenarios. Therefore, when choosing to use semi-tempered glass, it is essential to fully consider its application environment and safety requirements.
