Production performance requirements for single sheet tempered glass
In the production of a single sheet of tempered glass, the heating shall be ensured to the required temperature. In the process of single sheet tempered glass production, on the one hand, it is necessary to ensure that the single sheet tempered glass is heated to the required temperature and that the temperature of each part of the glass surface is even. At the same time, there should be no large temperature difference between the single sheet tempered glass surface and the middle. When heating a single piece of tempered glass, the temperature in the electric furnace shall be controlled according to the load condition of the electric furnace to ensure the heating temperature of a single piece of tempered glass. When setting the heating temperature of the electric furnace, the thickness of 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. When controlling the heating temperature of the electric furnace, the operator should understand the relationship between the temperature of the electric furnace and the heating time and the change value of the temperature of the electric furnace to the glass with different thickness to ensure the toughening performance of the glass. When heating the glass, the heating time of a single piece of tempered glass should be reasonably controlled, and at the same time, the layout of each piece of tempered glass and the clearance time of each furnace should be even, and the heating time of a single piece of tempered glass should be even.
On the other hand, it shall be carried out in a fast cooling speed single chip cooling tempered glass, when carries on the single chip cooling toughened glass, should try to use dry air as cooling medium, according to the actual thickness of the glass and other glass performance, reasonable control of cooling time, and ensure the monolithic toughened glass on the surface of the two cooling equilibrium. In addition, during the process of toughening, the glass should be kept moving.
