[China Glass Net] Tempered glass is obtained by first cutting the ordinary annealed glass into the required size and then heating it to about 700 degrees near the softening point, followed by rapid and uniform cooling. After tempering, the surface of the glass forms a uniform compressive stress, while the inside forms a tensile stress, which improves the bending and impact strength of the glass. The strength of the tempered glass is about four times that of ordinary annealed glass.
Tempered glass is attributed to safety glass. Tempered glass is actually a type of prestressed glass. In order to improve the strength of the glass, chemical or physical methods are generally used to form compressive stress on the surface of the glass. When the glass is subjected to external force, the surface stress is firstly offset, and then the bearing capacity is advanced to enhance the glass self-resistance. Wind pressure, cold and heat, impact and so on.
On the construction site, the welding slag is dropped on the tempered glass during the welding to form the welding boring. Can these tempered glass welding dies be removed?
In fact, there is no way to get rid of it.
Attachments that pass the temperature of 300 degrees splash onto the surface of the tempered glass, and the tempered glass is generally not damaged. The attachment on the surface of the glass can be removed with a gray knife, a paper cutter, etc., but it will leave a trace of unevenness.
The spot slag temperature generally exceeds 900 degrees and is difficult to eradicate. Generally, this situation can only change the glass.
The quenching and rapid heat properties of tempered glass are 3 to 5 times higher than that of ordinary glass, and generally can withstand temperature changes of more than 250 degrees, which has obvious effects on preventing thermal cracking. It is one of the safety glasses. To ensure the safety of qualified materials for high-rise buildings.
