triple -tier tempered glass product

Some forms of tempered glass are used for and

Rim tempered indicates a limited area such as the rim of the glass or plate is tempered and is popular in food service.

Toughened glass is used when strength, thermal resistance and safety are important considerations. The most commonly encountered tempered glass is that used for side and rear windows in automobiles, used for its characteristic of shattering into small cubes rather than large shards. Tempered glass is also used in buildings for unframed assemblies (such as frameless doors), structurally-loaded applications, and any other application that would become dangerous in the event of human impact. Toughened glass is used in some cell phones such as the and due to its scratch-resistant properties.

The strain pattern resulting from tempering can be observed with polarized light or by using a pair of sun glasses

Tempered glass must be to remove its internal stresses before cutting or grinding.

The greater contraction of the inner layer during manufacturing induces compressive stresses in the surface of the glass balanced by tensile stresses in the body of the glass. This compressive stress on the surface of the glass is typically as high as 50 MPa. It is this compressive stress that gives the toughened glass an increased strength. This is because any surface flaws tend to be pressed closed by the retained compressive forces, while the core layer remains relatively free of the defects which could cause a crack to begin. However, the toughened glass surface is not as hard as annealed glass and is slightly more susceptible to scratching. To prevent this, toughened glass manufacturers apply various coatings and/or laminates to the surface of the glass.

Toughened glass is strong, has enhanced thermal resistance, and breaks into small cuboid fragments rather than shards and is less likely to cause injury.

The features of tempered glass:
1.high intensity
2.withstand wide rapid temperature change
3.even no injury to people
