What Is The Cause Of Tempered Glass Surface?

1. White fog: Generally, white fog is generated because the tempering temperature is not enough.

2, tempered rainbow: now generally is the production of float glass, float glass production process is the process of glass paste on the surface of the tin groove under the action of gravity and its own tension, there must be one side is in contact with the tin surface, A small amount of tin infiltration occurs in this case. At the time of temperature, stannous oxide is produced. In the process of tempering, stannous oxide is reoxidized to form tin oxide under high temperature, and the volume expands, resulting in some micro cracks on the Building Tempered Glass surface. These cracks produce light interference when the glass is observed under special conditions and angles, resulting in a tempered rainbow. The solution is very simple. It is fine to sprinkle the polishing powder on the surface of the glass.

3, wind spot: This is formed during the cooling process, due to uneven temperature caused by uneven Tempered Laminated Glass stress, it will see the light and dark stripes on the surface of the glass under a special angle. Solution: Generally, air knife cooling is used instead of the traditional air hole cooling to avoid wind spots as much as possible.

4. Stress spot: The stress spot and the wind spot are similar, which is also caused by uneven stress. For example, during the heating process, there is a temperature difference between the edge of the furnace and the middle part, resulting in uneven stress. There are no methods to avoid stress spots in the world. The main factors are the natural factors such as orientation and local climate during installation to make the naked eye indistinguishable. It is recommended to replace the traditional single-chamber tempering furnace with a double-chamber tempering furnace, so as to eliminate the uneven stress happening.
