what advantage and disadvantage does toughened good glass have on can opening toughened glass

I believe that every day we will be exposed to a variety of glass products, such as glasses, glass doors, glass Windows and so on. Although we often come into contact with them, we do not know much about the kinds and properties of these glasses. And as a result of insufficient understanding of glass materials, often lead to a variety of problems. We will introduce whether the tempered glass can be drilled to help you further understand the advantages and disadvantages of tempered glass.

1. Can the tempered glass be perforated

Tempered glass can not be destructive processing (cutting and opening) of tempered glass must be in the original plate before the opening!

Toughened glass (Tempered glass/Reinforced glass) belongs to the safety glass. Tempered glass is glass of a kind of prestressing force actually, to enhance the strength of the glass, use the method of chemistry or physics normally, form in vitreous surface press stress, glass bears offset above all when outside force surface layer stress, so as to improve the bearing capacity, enhance the wind resistance glass itself, through sex, impact, etc.

The glass reaches a balance of its own stress, and when external forces (such as drilling or polishing) break the balance, the glass explodes -- breaking into slag

Two, what advantage and disadvantage does toughened glass have

Advantages and features of tempered glass:

1. The strength is several times higher than ordinary glass, bending resistance.

2. The use of safe, increase its bearing capacity improved brittle quality, even if small shards of toughened glass damage has no acute Angle, dramatically reduced the harm of human body. Of toughened glass be able to bear or endure urgent cold urgent hot property has 3 ~ 5 times than common glass, generally can withstand 250 degrees above the temperature changing, have apparent effect to prevent the thermal crack. Is one of the safety glass. To ensure high-rise buildings provide qualified materials safety assurance.

Disadvantages of tempered glass:

1. The tempered glass cannot be cut or processed any more. The glass can only be processed to the required shape and then tempered before it is tempered.

Although the strength of tempered glass is stronger than that of ordinary glass, tempered glass is likely to self-explode (self-rupture) when the temperature difference is large, while ordinary glass is not likely to self-explode.

3 toughened glass surface is uneven phenomenon, there are slight thickness thinning. After thinning because glass in thermal softening, after a strong wind make its rapid cooling, make its internal crystal glass gap smaller, pressure change, so after the toughened glass than in front of the toughened to thin. Normally 4-6 MM in toughened glass thinning after 0.2 0.8 MM, 8 to 20 MM in toughened glass thinning after 0.9 1.8 MM. The specific degree according to the equipment to decide, this is the cause of toughened glass can't be a mirror.
