What Affacts the Flatness of Tempered Glass

introduce you the main seven factors which may affact

 

 

Tempered glass is one widely used glass products in our home and kitchen appliances, furniture, electronics, due to its unqiue excellent safety and durability features. in order to fix the purchased tempered glass products 100% on our final products. the purchaser has a strict flatness requirement for those tempered glass products. while when we are manufacturing tempered glass sheet products, we can find sometimes the tempered glass sheet is not flat. and the experienced technicans will know what is wrong and do some adjustment to guarantee the flatness of the tempered glass. so do you know what is the problem?  in this article, lets find the answer together. 

 

7 Main Factors Affacting Flatness of Tempered Glass: 

 

There are mainly 7 reasons to affact the smoothness of tempered glass

 

1. Tempering furnace equipment is unstable‌: If the tempered glass is produced by a small factory, the stability of the tempering furnace equipment may be affected, resulting in wavy patterns on the tempered glass surface.

 

2. Poor quality of the original glass sheet‌: Poor quality of the original glass sheet can also cause unevenness. Some manufacturers claim to use high-quality original films, but in fact the quality may not be up to standard.

 

3. Tempering technology is not up to standard‌: The aging of the tempering furnace equipment or insufficient technical standards cannot achieve the ideal tempering effect, resulting in wavy deformation on the tempered glass surface.

 

4‌. Insufficient purity of glass‌: Insufficient purity of glass will lead to uneven surface and wavy lines in tempered glass.

 

5. Insufficient tempered glass thickness‌: Tempered Glass with a thickness below 5mm will have obvious deformation. Insufficient thickness will lead to a greater degree of softening, resulting in unevenness.

 

6. Uneven temperature‌: During the heating process of tempered glass, there is a temperature difference between the upper and lower surfaces, which causes uneven shrinkage during cooling, resulting in deformation.

 

7. Roller problem‌: The rollers in the heating section and air cooling section of the tempering furnace are deformed or worn, which will affect the flatness of the tempered glass.

Methods to Solve the Problem of Uneven Tempered Glass Include‌:

 

1. Adjust the temperature of the heating furnace‌: By adjusting the temperature at the bottom of the heating furnace, try to reduce the temperature difference between the upper and lower surfaces of the glass and solve the deformation problem caused by uneven temperatures on the upper and lower surfaces.

 

2. Replace high-quality rollers‌: Use high-quality ceramic rollers to prevent thermal deformation of the rollers at high temperatures and ensure the straightness and stability of the rollers

 

3. Regular maintenance of tempering furnace equipment‌: Regularly inspect and maintain tempering furnace equipment to ensure the stability and technical standards of the equipment and avoid deformation problems caused by equipment aging‌.
