Glass we all know, it is very good in transparency, to ensure that the intake of light, but ordinary glass also exists in a great safety performance, easy to hurt this feature many people love and hate it, but now the performance and quality of the glass are gradually becoming better, there is a tempered mirrors glass appeared in the market, which has a stronger than ordinary glass safety performance, so it can be used in many harsh conditions, even if broken will not cause harm to people, so it is now used in many different aspects, but mentioned it may be relatively unknown to many people. Can be used in many harsh conditions, even if broken will not cause harm to people, so it is now used in many different aspects, but it may be mentioned that many people are relatively unfamiliar, so I'm going to introduce you to the toughened mirrors glass, I hope to be able to help you.
A, tempered sight glass introduction
Tempered glass sight glass is a physical or chemical tempering of the glass piece, physical tempered glass has a safety performance, because the glass after physical tempering that the glass is heated to the softening point of the heating furnace near the softening point, and then in the cooling equipment with the cooling medium such as air to cool rapidly, in its surface to form compressive stress, which improves the tensile properties of the glass surface.
The strength of the glass is increased by 3-5 times. Tempered glass after heat treatment internal internal energy dramatically increased, the surface compressive stress is balanced by the internal tensile stress, when the impact energy exceeds the internal energy, the glass on the surface began to rupture and extends to the interior, under the action of the internal energy, the glass is torn into small pieces, the size and number of pieces with the high and low levels of internal energy, rupture of small pieces of small pieces of damage to the person is very small.
Tempered glass after tempering in the case of rapid heat or cold hot and cold deformation occurs, the surface of the compressive stress to offset the tensile stress generated by the deformation of the glass, so that the heat resistance of the glass has been improved, thermal shock can reach 280 ℃ -320 ℃. Therefore, physically tempered glass is a safety enhanced glass with good safety and reliability. Therefore, it is very practical to use the advantages of high bending strength and heat resistance of tempered glass to make the observation window of high-pressure container in the chemical industry.
Second, the use of tempered glass sight glass
Tempered glass, also known as safety glass, it is damaged first in the inner layer, caused by the role of tensile stress damage caused by the crack propagation speed is very fast, at the same time, the outer layer of the compressive stress has to keep the broken inner layer is not easy to peel off the role of the tempered glass in the rupture, only produces a small fragments of no sharp corners.
Tempered glass can be used in a variety of applications.
Tempered glass weight has a large mutual balance of stress distribution, so generally can not be cut. In tempered glass processing, the glass surface cracks are reduced and the surface condition is improved, which is the reason for the high strength and better thermal stability of tempered glass. Because tempered glass is a safety enhanced glass, impact resistance, heat resistance has good safety and reliability, it is used in the following fields:
1, aviation field.
Tempered glass has high impact resistance, composite glass can withstand the impact of 550km/h speed bird.
2, construction field.
Tempered glass as a weighing material used in the overall structure of the overpass, the use of tempered glass bending strength of the advantages of the glass is also designed into a tower-shaped support columns, modeling base and so on. Modern construction of glass windows, glass doors, glass barriers, glass partitions, bathroom glass, staircase guard glass, etc. are using this safety glass.
3, the automobile industry.
According to the requirements of safety, explosion-proof, automobile front windshield, side windshield glass are used in tempered glass or regional tempered glass.
4, train, ship transportation.
Trains, ships and other means of transportation windows, doors are tempered, hollow tempered or tempered laminated glass.
5, household appliances, daily furniture, sanitary ware and so on.
Tempered glass is basically all over the home appliance industry, small electronic monitors, weighing scales, large microwave oven door, oven door, refrigerator door, hood shroud.
6, the electronics industry.
Computer monitor protective screen, projector protective screen, industrial TV monitor, computer touch screen, cell phone display, amusement machine display, projector internal heat-resistant protective screen.
7, chemical field.
Tempered glass using the characteristics of 200 ℃ temperature difference, do the organic material molding plate preparation of templates, dosage containers. The use of tempered glass with high bending strength, heat-resistant advantages to do high-pressure container observation window, high-pressure container sight glass, pipeline sight glass, speculum, fire-viewing window, fire-viewing sight glass, tempered glass sight glass observation holes, etc..
8, other fields.
Tempered glass wear-resistant, heat-resistant performance to do buildings, spotlights, floor lamps protective glass; medical equipment shadowless lamp protective glass; printing machinery, heat-resistant glass screen; museum showcases, exhibition halls, windows, commercial counters and so on.
Tempered sight glass is a new type of glass material, but because of its superior quality is applied to many areas, and in the safety performance is also a great guarantee, if the family in the choice of installing the glass or in the choice of the time in the installation of the work of the editor, I think that this is a good choice, because of its strength is the ordinary glass of 3-5 times, which means that it is more than ordinary glass Strong and durable, can have a longer period of use, which is also economically more affordable, but in the purchase, I think of course the quality is still the most important, we do not ignore the quality to less consider the price Oh, I hope that the above editorial information for you to be able to help you.
