Using tempered glass can pose a security risk in some situations because of the tendency of the glass to shatter completely upon hard impact rather than leaving shards in the window frame. However, there is still a chance that it scratches due to daily use. 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. 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”. Learn the translation for ‘tempered’ in LEO’s English ⇔ German dictionary. Lernen Sie die Übersetzung für 'tempered' in LEOs Englisch ⇔ Deutsch Wörterbuch. Tempered glass protectors offer better resistance against scratches, and more importantly, insulates your screen a bit against drops. Tempered glass is used for its safety and strength in a variety of applications, including passenger vehicle windows, shower doors, aquariums, architectural glass doors and tables, refrigerator trays, mobile phone screen protectors, bulletproof glass components, diving masks, and plates and cookware. Now I know, tempered glass prevent my phone from being damage even it was directly heated by the sun. From now on, the tempered glass protector can no longer have adhesive on the entire side of the glass which was a norm for manufacturing flat screen tempered glass protectors. Tempered glass is made to absorb the impact when you let your phone fall on hard surfaces. How to use tempered in a sentence. 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. Barr, Johathan. Metallurgy . Tempered glass can be made from annealed glass via a thermal tempering process. [citation needed]. Again, you rather have the tempered glass broken than the screen of your phone itself. How is tempered glass made? 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. Passenger vehicles, for example, have all three requirements. However, we are mostly interested in its application in screen protectors for mobile phones and other devices. elements for building fronts and balustrades, [...] laminated sa fety glass made of tempered or semi- tempered glass or glass with technically. Glass can scratch anything below a 5, such as iron, but glass can be scratched by anything above a 5, such as quartz. The windscreen or windshield is instead made of laminated glass, which will not shatter into pieces when broken while side windows and the rear windshield are typically tempered glass. @Prashant, gorilla glass is definitely more scratch proof than tempered glass. So what does this mean for you, the consumer? Tempered glass protectors are common accessories for mobile devices and in their look are quite similar to plastic covers. Having a specified temper or disposition. Of the two, it makes more sense to buy a tempered glass protector today. Fully tempered 6-mm thick glass must have either a minimum surface compression of 69 MPa (10 000 psi) or an edge compression of not less than 67 MPa (9 700 psi). "Rim-tempered" indicates that a limited area, such as the rim of the glass or plate, is tempered and is popular in food service. I’d be curious to know since I’m looking at getting new windows. Polishing the edges or drilling holes in the glass is carried out before the tempering process starts. One of the main characteristics of tempered glass is that it breaks differently from standard glass. It is forced to cool rapidly, which additionally increases the breaking point. 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. Cutting, grinding, and sharp impacts after tempering will cause the glass to fracture. Tempered glass is made by heating and cooling a piece of standard glass in a tempering furnace. Doors are tempered glass which rise vertically to close, providing complete access to the wash chamber for ergonomic loading and unloading using a trolley and rack system. tempered glass translation in English - French Reverso dictionary, see also 'temper',temperate',temperance',temperament', examples, definition, conjugation These are teardrop-shaped bits of glass which are produced by allowing a molten drop of glass to fall into a bucket of water, thereby rapidly cooling it. 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. Tempered glass is a type of safety glass, designed so that if it breaks, it will not shatter into shards. This waviness is a significant problem in manufacturing of thin film solar cells. The glass is then rapidly cooled with forced air drafts while the inner portion remains free to flow for a short time. If your device, on the other hand, is a mid-range phone, like that of most users, the 2.5D screen protector protects your mobile phone from knocks, scratches and fingerprints. Before we start learning how to cut tempered glass, there are some items that one should be acquainted with before anything else. Tempered glass is created by heating and then quickly cooling the material – and thus comes with a different structure. [4] The compressive stresses on the surface of tempered glass contain flaws, preventing their propagation or expansion. Because of the balanced stresses in the glass, damage to any portion will eventually result in the glass shattering into thumbnail-sized pieces. Ideus’ range of 4D tempered glass protectors covers the entire screen. 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”. [1][2] 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. 3. [11], Francois Barthelemy Alfred Royer de la Bastie (1830–1901) of Paris, France is credited with first developing a method of tempering glass[12] by quenching almost molten glass in a heated bath of oil or grease in 1874, the method patented in England on August 12, 1874, patent number 2783. This is also the type of glass used for oven doors. That’s pretty cool that the thermal processing method of tempering actually allows the glass to be safer when it shatters. In the event of breakage, tempered glass fractures into small, relatively harmless pieces rather than jagged shards. 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. Because large, sharp glass shards would present additional and unacceptable danger to passengers, tempered glass is used so that if broken, the pieces are blunt and mostly harmless. [10], Nickel sulfide defects can cause spontaneous breakage of tempered glass years after its manufacturing. Tempering puts the outer surfaces into compression and the interior into tension. In fact, tempered glass is four to five times stronger than annealed, or untreated, glass. glaserindex.de. Self published. What makes it different from standard glass or plastic screen protectors? It can happen in an instant; tiny pieces of glass can come raining down. made less intense or violent, especially by the influence of something good or benign: justice tempered with mercy. Manufacturers and brands include Glasslock, Pyrex, Corelle, and Arc International. Other typical applications of tempered glass include: Tempered glass is also used in buildings for unframed assemblies (such as frameless glass doors), structurally loaded applications, and any other application that would become dangerous in the event of human impact. Tempered glass is also used in the home. Wikipedia (0.00 / 0 votes) Rate this definition: Tempered glass. In about 1660, Prince Rupert of the Rhine brought the discovery of what are now known as "Prince Rupert's Drops" to the attention of King Charles II.
