Tempered glass is obtained by cutting ordinary annealed glass into the required size, heating it to around 700 degrees near the softening point, and then rapidly and uniformly cooling it. After tempering treatment, uniform compressive stress is formed on the surface of the glass, while tensile stress is formed inside, which improves the bending and impact strength of the glass. The strength of tempered glass is more than four times that of ordinary annealed glass.

Tempered glass is classified as safety glass. Tempered glass is actually a type of prestressed glass. To improve the strength of glass, chemical or physical methods are generally used to create compressive stress on the surface of the glass. When the glass is subjected to external forces, the surface stress is first counteracted, and then the load-bearing capacity is advanced to enhance the glass's own resistance to wind pressure, heat and cold, impact, etc.

During the production process, welding slag falls onto tempered glass during welding, forming welding scars. Can these scars be removed except for tempered glass welding scars?

It's actually impossible to remove it.

Attachments that cross a temperature of 300 degrees splash onto the surface of tempered glass, and tempered glass generally does not break. The attachments on the surface of glass can be removed with tools such as ash knives or paper cutters, but they will leave uneven marks.

The temperature of spot welding slag generally exceeds 900 degrees, making it difficult to remove. Usually, this situation can only be resolved by replacing the glass.

The rapid cooling and heating resistance of tempered glass is 3-5 times better than that of ordinary glass, and it can generally withstand temperature differences of more than 250 degrees, which has a significant effect on preventing thermal cracking. It is a type of safety glass. To ensure the safety of qualified information provided for high-rise buildings.
