Recently observed steadythe popularity of the use of glass products in the design of premises, including in the external glazing. The current production technologies allow to get clean glass of absolutely any shape and size. However, no matter how beautiful it is, it does not make it the most protected from mechanical damage. In fact, when a glass falls at least a few centimeters, it is first covered with small cracks, and then instantly crumbles. But the engineers took into account this moment, and therefore now almost all the facade design of the premises uses a special tempered type of glass. What makes it so popular, and what are its characteristics?
According to GOST, tempered glass isa material that, during production, is heated to a temperature of 650-700 degrees Celsius and then cooled rapidly to minimum values. Thus, due to the difference in heating, a heat treatment process takes place, i.e. quenching. As a rule, the output of such material is highly reliable and impact resistance. Experts have calculated that this type of tempered glass is 4 times stronger than the one called ordinary stalinite. In addition, you should pay attention to the safety of its use. Fragments of this material are distinguished by lower cutting properties. At the same time, the usual stalinite, when dropped, breaks into hundreds of small pieces of glass that bite into the skin so quickly that the pain from their presence under the skin occurs only on the following days. Fragments of tempered glass are more obtuse, which prevents the risk of serious injury to a person.
Production of tempered glass is carried out on special technical equipment, while the dimensions of the material obtained can be as follows:
Before tempered glass masters chooseits necessary dimensions and, if possible, cut it to the desired shape. Why it is impossible to process such glass after quenching? The fact is that the surface of this material, along with high strength, does not make it possible to make any changes in its shape. And this means that cutting and drilling the surface of a hardened part simply makes no sense. It should be noted that the glass can be hardened only with the help of sophisticated technical equipment. Just heat a piece of glass on the stove and quickly immerse it in cold water, you will not succeed. Such material will simply crumble into small fragments or, at best, simply crack. Therefore, if you want to temper glass, please contact this request to specialized companies that provide such services.
The temperature range of operation of suchThe material ranges from -150 to +300 degrees Celsius. And this is despite the fact that Stalinite can withstand a temperature difference of only 40 degrees. In this regard, an increasing number of construction companies are wondering "how and where to temper glass for exterior glazing?"
