Description:

Unlike annealed glass or what we know as “ordinary” glass, toughened tempered glass does not break into large jagged shards that can cause serious injuries. Instead, it breaks into smaller granular pieces that are less likely to cause harm. This is why toughened tempered glass is used in passenger vehicle windows, refrigerator trays, shower enclosures, microwave ovens, and other things we use on a regular basis.
Tempered glass is also much stronger than annealed glass. It undergoes a complex manufacturing process that toughens it both physically and thermally.

Heat resistance of toughened tempered glass​:

One benefit of toughened tempered glass is the ability to stand up to moderate heat (470°F). The process that creates this strengthened glass also makes it heat-resistant. This makes tempered glass a great solution for a situation where there is a danger of the glass breaking due to impact or moderate heat. Tempered glass is often used for fireplace doors (not woodstoves), on masonry and prefabricated fireplaces. If tempered glass is exposed to higher temperatures, it gradually weakens the structure of the glass thus making it more susceptible to breakage. Toughened tempered glass is not recommended in wood burning applications.

Toughened tempered glass screen printing :
Screen printing glass is inorganic glaze (also known as ink),printing to the glass surface, and then by drying, tempered or hot processing, the glaze permanent dry or sintering in the glass surface and get a kind of wear-resisting, resistance to acid and alkali of decorative glass products. This product has a high functional and decorative. It has many different colors and patterns, such as strip, mesh and the electric design and so on. Also can according to customers' different needs further design pattern.

Toughened Tempered Glass usage area:
Automobile, train, shipping, building, furniture, automatic door, escalator, fireplace, etc. CnC tempered glass is used when strength, thermal resistance and safety are important considerations. CNC tempered glass can be found in shower doors, patio doors, store fixtures and other applications that could be dangerous in the case of human impact.

Quality Inspection Item

1, Toughened Tempered Glass Appearance, In the daytime (or in the case of similar brightness), observe the toughened tempered glass vertically for 5 seconds with naked eyes or with the aid of glasses from a distance of 50cm or a distance of one arm length. No dirt or scratch, edge and corner, printing effect.

2, Printing appearance: the toughened tempered glass printing area (ink covered area) of the control panel is judged under the condition that the back has opaque cover (black background), and under the black background, it is acceptable that the front is invisible.

3, Evenness of toughened tempered glass: bow shape ≤ 0.5%; there is one place (one peak and one trough) allowed for every 610mm of waveform;

4, Granularity test: two pieces of tempered glass are selected for each batch of CNC tempered glass to be tested, and the place where the center of the long side of the glass plate is 13mm higher than the bottom edge is taken as the breaking point (see figure). After the glass is broken, the two areas with the largest granularity are selected in a 50mm*50mm box for counting. The number of crack-free particles completely contained in the 50mm*50mm box must be ≥50, and the largest particle size must be ≤ 15 mm * 8 mm.

5, Impact test: drop a steel ball with a diameter of 51mm and a weight of 535g from the CNC tempered glass surface 648mm, and impact the center of the glass plate once to ensure that the glass does not break.
