Tempered glass is currently used in a wide range of safety glass form, in the construction, automotive, home improvement and home appliances has a wide range of applications. With the continuous development of tempered glass technology, the application of tempered glass continues to expand, people on the quality of glass products continue to improve, therefore, should pay attention to the production of glass and quality inspection to ensure that the quality of tempered glass.
Production performance requirements for tempered glass
In the production of tempered glass, should be heated to the required temperature. In the production of tempered glass, on the one hand, should ensure that the tempered glass heated to the required temperature to ensure that the glass surface of the various parts of the temperature to be uniform, while the tempered glass surface and the middle can not be a large temperature difference. When the tempered glass is heated, the temperature of the electric furnace should be controlled according to the load condition of the electric furnace to ensure the heating temperature of the tempered glass. When setting the heating temperature of the electric furnace, the thickness of the tempered glass should be considered comprehensively. In order to make the tempered glass thinner, the heating temperature of the electric furnace should be higher. In order to make the tempered glass thicker, the heating temperature of the electric furnace should be lower. In the electric furnace heating temperature control, the operator should understand the electric furnace temperature and the heating time of the relationship between the temperature and the furnace temperature of different glass changes in the value of glass to ensure that the steel properties. When heating the glass, it should be reasonable to control the heating time of the tempered glass, while ensuring that the layout of each furnace glass and the furnace evenly spaced time to ensure that the glass heated evenly. On the other hand, it should also be the fastest cooling rate of tempered glass cooling, in the tempered glass cooling, should try to use dry air as a cooling medium, according to the actual thickness of the glass and other properties of the glass, reasonable control of the cooling time and to ensure that The two sides of the tempered glass are cooled and balanced. In addition, during the tempering process, the glass should be kept in motion. In the process of steel should pay attention to the thermal swing movement, to ensure that the glass heated evenly, but also should pay attention to cold pendulum movement, to ensure that the glass uniformity, while ensuring the glass in the steel during the movement, the glass surface does not appear scratch and deformation left trace. In the production of tempered glass, the quality of the original plate glass has certain requirements for the production of glass to the original plate glass is strictly prohibited layer miscellaneous, burst, scratches and bubbles and other quality problems, and tempered glass in the production process of wind Cold crushing phenomenon, to ensure the quality of tempered glass.
In the choice of the purchase of steel furnace in the process, should be more to the actual production line to study, observe the entire steel process. Glass flatness, particle size, etc. can be relatively simple comparison. The tempering cost of the steel furnace is also very important for the deep processing enterprises.
In order to ensure the performance of tempered glass during the production of tempered glass, it should be ensured that the tempered glass is heated to the temperature requirements and the tempered glass is cooled at the fastest cooling rate and the movement of the tempered glass is ensured. In the inspection of tempered glass, should pay attention to the size of the inspection and deviation test, thickness and deviation test, bending and impact resistance test, the appearance of quality inspection and debris inspection, to ensure that the quality of glass.
