Glass is an integral part of Windows and doors, early architectural glazing is a single layer of flat glass, developed to the tempered glass, hollow glass, laminated glass, bullet-proof glass. Most of today's Windows and doors use tempered glass. Facet out of the following 4 ways to make you talkTempered glassCommon sense.

First, how to identify glass and ordinary glass?

1, see glass signs

Glass tempering or corner of the 3C logo, 3C tags (scrape away) basically are tempered glass. Glass processing procedure is the commonFloat glassCut the size you want, and then polishing, cleaning, playing with ink national compulsory certification CCC mark, into the glass after tempering furnace product is not cut or processed. Ink after the high temperature usually is scraped away. (3C logo on the glass if your home can rub with my hands, that basically can tell is fake glass. )

2, to see if a slight deformation

From the side to see if the glass has a slight deformation because the glass temperature, when fired, there will be a slight deformation of the phenomenon, which can be seen only from the side of the glass front is generally difficult to see.

3, see fragments of glass

Ordinary glass breaking is large, sharp edges, easily hurt. Behind the glass breaking is granular, corner is a bit dull, not easy to hurt.

Second, tempered glass by shape: flat tempered glass and curved tempered glass

Generally more common flat tempered glass thickness 4, 5, 6, 8, 10, 12, 15, 19mm, eight; more commonly used surface tempered glass thickness 5, 6, 8, 10MM four.

Three, the tempered glass technology: physical tempered and chemically

Physical tempered flat glass or float glass under certain conditions, by quenching or processed into wind quenching method. Chemical tempered glass is ordinary plate glass or float glass by ion-exchange method, the glass surface molecular changes, make the glass surface laminate stress way of processing.

Four characteristics, tempered glass:

1, high impact strength

Four to five times higher than ordinary Glass; bending strength, high 5 times than ordinary flat glass; and good thermal stability, can handle up to 200 ° c temperature change, as well as features such as smooth, transparent, not cutting. In case of strong impact damage, debris dispersed fine granules, no sharp edges and corners, it is also known as safety glass.

2, after the steel thickness slightly thinner

Thinning due to glass after the hot-melt soften, after strong wind makes its rapid cooling, so that the gap between glass crystal is less pressure, so the glass in tempered than in front of the steel to be thin. General 4-6mm glass after tempering thinning thinning 0.2-0.8mm,8-19mm glass after tempering 0.9-1.8mm. Specific degrees according to the equipment to decide.

Through a small addendum to the above introduction, I believe your knowledge of tempered glass and raised to new heights.
