Customized irregular Cnc tempered Glass Physically Tempered Finish

Description:

CnC Tempered Glass is processed through heating ordinary glass evenly first and then cooled off according to different thickness with corresponding cooling speed when approach the soften point, which makes inner strong permanent stress which is brought about inside the glass, inner tension stress and outer pressure stress in the steady balanced state of stress and has changed the intrinsic physics performance of glass, overcame the intrinsic shortcoming of glass, greatly improved the serviceability of glass and expanded the range of application.

Features:

1. CNC tempered glass is a kind of safe glass and the fragment of which does no harm to people.
2. it's 4-5 times safer and harder than ordinary annealed glass.
3. Special logo and pattern can be printed on tempered glass.
4. Outstanding performance in resisting thermal stress and wind-load.

CNC 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, CNC tempered glass Appearance, In the daytime (or in the case of similar brightness), observe 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 CNC 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 CNC 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.
