Technical quality requirements for tempered glass

Tempered glass is a type of specially treated glass. Through heating and rapid cooling, compressive stress is generated on the glass surface, and tensile stress is generated internally, thereby improving the glass's strength and impact resistance.

 

Technical Quality Requirements for Tempered Glass:
1. Thickness: The thickness of tempered glass should conform to national standards and must not exceed the specified tolerance range.

2. Flatness: Flatness refers to the smoothness of the glass surface. It should conform to national standards, and the surface should be free of defects such as unevenness or waviness.

3. Heat Treatment Quality: The heat treatment quality of tempered glass should conform to national standards, and the surface should be free of obvious heat treatment marks or defects.

4. Curvature: The curvature of tempered glass should conform to national standards and must not exceed the specified tolerance range.

5. Surface Quality: The surface of tempered glass should be smooth and clean, free of defects such as bubbles, dust, and scratches.
