tempered glass meaning

Such stresses cause the glass, when broken, to shatter into small granular chunks instead of splintering into jagged shards as ordinary annealed glass does. Tension applied to the glass can drive crack propagation which, once begun, concentrates tension at the tip of the crack driving crack propagation at the speed of sound through the glass. However, there are also specialist manufacturers that offer a fully tempered/toughened drinkware solution that can bring increased benefits in the form of strength and thermal shock resistance. Tempered glass passes through the same process only that its annealing process is made shorter. Though the underlying mechanism was not known at the time, the effects of "tempering" glass have been known for centuries. made less intense or violent, especially by the influence of something good or benign: justice tempered with mercy. 1 ways to abbreviate Tempered Glass. And it’s only 0.33 mm thick. [citation needed]. Whereas normally, glass would break into big uneven pieces, tempered glass shatters into small even pieces. Tempered or toughened glass is a type of safety glass processed by controlled thermal or chemical treatments to increase its strength compared with normal glass. Now I know, tempered glass prevent my phone from being damage even it was directly heated by the sun. Building codes in the United States require tempered or laminated glass in several situations including some skylights, glass installed near doorways and stairways, large windows, windows which extend close to floor level, sliding doors, elevators, fire department access panels, and glass installed near swimming pools.[5]. They can withstand a blow from a hammer on the bulbous end without breaking, but the drops will disintegrate explosively into powder if the tail end is even slightly damaged. Definition of Tempered Glass in Construction A process that is used on glass that rapidly heats the glass, then rapidly cools the glass. Most touchscreen mobile devices use some form of toughened glass (such as Corning's Gorilla Glass), as do some aftermarket screen protectors for these devices.[6]. Tempered glass also more closely mimics the feel of your actual screen, which makes it much more pleasant to use. Tempered Glass Screen Protector. Temperglas ist ein Glas, bei dem durch Wärmebehandlung gezielt mechanische Spannungen im Material erzeugt werden und dadurch die Bruchfestigkeit gegenüber mechanischer oder thermischer Beanspruchung erhöht wird. What you need to cut tempered glass. Define Tempered glass. An alternative chemical toughening process involves forcing a surface layer of glass at least 0.1 mm thick into compression by ion exchange of the sodium ions in the glass surface with potassium ions (which are 30% larger), by immersion of the glass into a bath of molten potassium nitrate. Tempered glass must be cut to size or pressed to shape before tempering, and cannot be re-worked once tempered. Therefore it’s better still if you have tempered glass added, because you rather have your cheap tempered glass scratches than the phone screen itself. As a result of the increased surface stress, when broken the glass breaks into small rounded chunks as opposed to sharp jagged shards. Chemical toughening results in increased toughness compared with thermal tempering and can be applied to glass objects of complex shapes.[7]. @Prashant, gorilla glass is definitely more scratch proof than tempered glass. Tempered glass is created by heating and then quickly cooling the material – and thus comes with a different structure. Because of the balanced stresses in the glass, damage to any portion will eventually result in the glass shattering into thumbnail-sized pieces. Any cutting or grinding must be done prior to tempering. Thanks to the aforementioned heat resistance, tempered glass will bring down the chances of your phone being damaged by higher temperatures. Learn the translation for ‘tempered’ in LEO’s English ⇔ German dictionary. The process of tempering the glass actually alters the chemical compound of the glass, and when it breaks it shatters into small, blunt-edged pellets that are significantly less sharp than the large, dangerous shards that come from plate glass. properly moistened or mixed, as clay. Manufacturers and brands include Glasslock, Pyrex, Corelle, and Arc International. This gets rid of the danger of sharp edges and makes it a much safer option should something happen – for this reason, tempered glass is often referred to as “safety glass”. The granular chunks are less likely to cause injury. Unlike standard glass, tempered glass is cooled much more slowly during the annealing process which allows it to be much more sturdy and strong than its nontempered cousin. [3] For it to be considered safety glass, the surface compressive stress should exceed 100 megapascals (15,000 psi). Due to its safety advantages and heat resistance (resulting from the manufacturing process), tempered glass is used in ovens, coffee machines, computer screens, windows, shower doors and more.
