Tempered Glass Production Performance And Quality Inspection To Ensure Quality
- Oct 23, 2017 -

Tempered glass is currently widely used in the form of safety, in the construction, automotive, home improvement and household appliances has a wide range of applications. With the continuous development of toughened glass technology, the application field of toughened glass has been enlarged, and the requirement of tempered glass product quality has been continuously improved, therefore, we should pay attention to the production performance and quality inspection of tempered glass to ensure the quality of tempered glass.

In the production of tempered glass, should be ensured heating to the required temperature. In the process of tempered glass production, on the one hand, should ensure that the tempered glass heating to the required temperature, to ensure that the glass surface of all parts of the temperature uniformity, while the tempered glass surface and the middle also can not appear large temperature difference. When the tempered glass is heated, the temperature in the furnace should be controlled according to the load of the electric furnace to ensure the heating temperature of the tempered glass. In the setting furnace heating temperature, should consider the thickness of tempered glass, in order to make tempered glass thinner, furnace heating temperature should be higher, in order to make tempered glass thicker, furnace heating temperature should be lower. In the furnace heating temperature control, operators should understand the furnace temperature and heating time of the relationship between the furnace temperature and thickness of different glass changes, to ensure the performance of FRP. When heating the glass, it is reasonable to control the heating time of the tempered glass, and ensure that the arrangement of each furnace and the clearance time of each furnace is even, to ensure that the tempered glass is heated evenly. On the other hand, should also be the fastest cooling speed tempered glass, in the tempered glass cooling, should be as far as possible to use dry air as cooling medium, according to the actual thickness of glass and other properties of glass, reasonable control of cooling time, and ensure that the tempered glass two-side cooling equilibrium. In addition, in the tempering process, the glass should be ensured to keep moving. In the tempering process should pay attention to the hot swing movement, to ensure that the glass heating uniformity, but also should pay attention to cold pendulum movement, to ensure that the glass fiber reinforced plastic, while ensuring that the process during the tempering, glass on the surface does not appear scratches and deformation left traces. In the production process of tempered glass, the quality of the original plate glass has certain requirements, for the glass production of the original plate is strictly prohibited to appear layer miscellaneous, explosion edge, scratches and bubbles, and other quality problems, and tempered glass in the production process of wind-cooled broken phenomenon, to ensure the quality of tempered glass.

Tempered glass belongs to safety glasses. Tempered glass is actually a kind of prestressed glasses, in order to improve the strength of glass, usually using chemical or physical methods, on the glass surface to form compressive stress, glass under the external force of the first offset surface stress, thereby improving the load-bearing capacity, enhance the glass itself against wind pressure, the thermal, impact, etc.

Characteristics:

The first is that the strength is several times higher than the ordinary glass, bending resistance.

The second is the use of security, its capacity to improve the fragile nature, even if the glass damage is not sharp-angle small fragments, the human body damage greatly reduced. Tempered Glass is $number than ordinary glass, which can withstand the change of temperature difference of more than 150LC, and has obvious effect on preventing thermal burst. is a kind of new glass.

Security: When the glass is damaged by external forces, debris into a honeycomb-like small obtuse-angle particles, not easy to damage the human body.

High-strength: the same thickness of the tempered glass impact strength is common glass $number times, bending strength is ordinary glass $number times.

Thermal Stability: Tempered glass has good thermal stability, can withstand the temperature difference is 3 times times of ordinary glass, can withstand the temperature difference of 200 ℃.

Flat tempered, curved tempered glass belongs to safety glasses. Widely used in high-rise building doors and windows, glass curtain wall, indoor partition glass, lighting ceiling, sightseeing elevator channel, furniture, glass guardrail and so on.
