Tempered glass for industry and for telephones

Tempered glass is a usual transparent sheet material. It is created by heating to a temperature of 650-680 ° C. After reaching this mark, there is a sharp and even cooling with air. Due to the use of such technology, residual compressive stresses appear, which allows achieving maximum strength, reliability and resistance to temperatures. Moreover, if such a tempered glass breaks, it will do less harm to others than the usual. This is due to the fact that when the material is destroyed, the material is broken up into blunt small fragments that are not capable of causing really serious injuries.

It's about the protected glass, its use in the industry we'll talk about in the article. Also consider how to create such material and what its interaction with modern gadgets.

Features

Due to such properties of tempered glass, as safety and strength, it is often used in construction, railroad, automotive, furniture, psychiatry. Moreover, it is used to create dishes, showcases, barricades on hockey grounds.

Another useful property is tempered glass - heat resistance. What can it do? When glazing homes and premises there is no risk of subjecting the substance to a thermoshock. That is, such material easily withstands even the strongest temperature changes.

What can make the glass described vulnerable? Only a blow to the butt. Such a mechanical action can easily break the tension of the glass and break it completely. This effect is used in modern design styles. Sometimes a door is installed with glass inserts with decorative cracks present on it. These small flaws, when combined, create a pattern in the form of a web.

Tempered glass can not be drilled, cut and subjected to other treatments.

Use in the automotive industry

Tempered glass is widely used in the manufacture of vehicles. It is used to create lateral (sometimes rear) glass. For frontal use of this material is prohibited. This is due to a violation of safety regulations.

The front windows are made of a triplex of non-hardened material. The same laminated glass has one interesting nuance. After cracking along the entire length, the window quickly loses its transparency. However, this does not prevent the use of tempered glass in automotive architecture.

How are glass quenched?

We have already briefly described the process of tempering glass, but consider it in some detail. Below are specified all the steps that must be followed:

• It is necessary to cut the material in order to give it the desired shape.
• Masters should check the glass for defects. If cracks or shots are found, emptiness, then the processing of such material, and also its further use is prohibited.
• The edges must be covered with an abrasive substance.
• The glass should be washed.
• The material must then be heated in the oven to the temperature indicated above.
• The last step is to fan the product from all sides with fans.

How to temper glass at home?

Independently this material can be hardened in two ways. We are talking about the use of a special film and leave. Let's consider both options in more detail.

The film can be purchased at a low price in any store that specializes in selling similar products. With its help, you create protective tempered glass for phones and other gadgets. Such material can protect the device from scratches and other deformations. However, not all blows he is able to withstand. Therefore, due to even the slightest damage, the transparent product can break.

A holiday is called a method that strengthens any glass products. It can be like a can, a glass, a salad bowl, and completely different utensils. To make a similar procedure is easy at home, so it is so common. What do I need to do? Pour the sand onto the bottom of the metal pan (in which water was previously poured), set the glass on it. After placing the container on a small fire, it is necessary to wait for the boil. So "boil" about 20 minutes. At the end of this time, allow the material to cool completely.

Advantages and disadvantages

Tempered glass, reviews about which are positive, has its drawbacks and advantages. They are associated with the following properties of the material:

• It is easy to take care of such a glass.
• It is durable.
• Easily withstands temperature changes.
• Flexible, if you exercise evenly.
• Quite safe. Injuries from tempered glass are excluded.

What do consumers notice from the shortcomings? Due to the special technology of making edges, glass can easily be damaged. Closer to the edges, small cracks can appear. However, this does not affect the integrity of the material.

What is better - tempered glass or film?

Tempered glass on the phone is in demand. However, some buyers can not choose between it and the film. The most optimal professionals consider glass. Why? This material will get rid of the problem of permanent fingerprints on the display. It is smooth and does not slip. If the phone falls, the glass breaks into a thousand fragments, but the screen remains intact. It also takes a hit on yourself when scratches occur. That's why tempered glass on the phone will be an ideal option.
