Tempered Glass Excellent Quality, Stable Performance

What are the requirements for the thickness of the tempered glass? Depending on the purpose, there is a difference in thickness selection.

It is understood that the quality of tempered glass, stable performance, widely used in residential, hotels, hotels, office buildings, schools, hospitals, shops and other occasions. Can also be used for trains, cars, ships and so on.

In the choice of tempered glass, the thickness depends on the size and size of doors and windows, larger glass to choose thicker. This ensures the firmness of the glass.

In addition, in the choice of tempered glass, if it is high-rise buildings, then a little thicker than the multi-layer. Coastal areas, especially in areas of typhoon and sandstorms, should be thicker. In short, the choice of local conditions need to consider the local climate and the floor.

 Nowadays, with the general improvement of people's life requirements of the application of tempered glass has become more and more widely, and look forward to a lot of buildings are selected by the windows of this glass, with the glass instead of the traditional wall is not only beautiful, But also enhance the house's lighting rate, and even home with the coffee table and table also become inseparable from this type of glass.

And a large number of applications also means that the improvement of the quality requirements in the tempered glass during the steel must be heated to the corresponding temperature, to ensure that the glass surface of the various parts of the temperature to be even the difference can not be too large. And the glass should be cooled as quickly as possible with a faster cooling rate, and the glass thickness and other properties of the glass determine the cooling rate.

In the course of tempered glass, the ideal medium for the cooling phase is dry, cold air, and the cooling capacity per unit area is determined to ensure uniform cooling. At the same time in the course of the glass to keep the movement, the glass surface can not be scratched or even left the traces of deformation.

With the extensive use of tempered glass in life, the quality of its increasingly demanding, making the glass manufacturers are more concerned about the quality of glass control, and quality control of the key, often depends on the quality of the process. The glass must be heated to the corresponding temperature, the glass surface of the various parts of the temperature to be uniform, the difference can not be too much to control the data to master the three elements.

First, according to the load of the furnace, select a reasonable heating temperature and effectively control the furnace temperature. The heating of the glass in the tempering furnace is mainly conduction, radiation and convection. Here, the electric furnace load does not refer to the area occupied by the glass in the electric furnace, but the relationship between the glass thickness, the heating temperature and the heating time. At present, most manufacturers use the steel furnace heating section can generally be divided into many very small heating area, under normal circumstances, in the central heating element heating area, there are always glass in the endothermic, in the electric furnace area, has been There is a glass, which is regional, the heating effect is also regional, if the electric furnace within a region of the heat consumption exceeds the heating effect,Tempered Glass the temperature inside the region began to decline, which is overload, the success of glass and Whether it depends mainly on the lowest temperature of the glass plate, once the electric furnace has a overload phenomenon, the furnace temperature will drop, resulting in glass cooling in the cooling section caused by broken.

Second, choose a reasonable heating time. The heating power of the tempered furnace is constant. The heating time is usually set to about 35 to 40 seconds per mm of glass. For example, the heating time of 6mm glass is about 6 × 38 seconds = 228 seconds. In the thickness of less than 12mm ordinary flat glass, when the glass thickness of 12 ~ 19mm, the heating time of the basic calculation method is about 1mm thickness of glass about 40 to 45 seconds.

Third, to achieve uniform heating, glass in the layout of the table is also very important. The rational arrangement of the film is to ensure the uniformity of the longitudinal and transverse loads in the furnace, that is, the arrangement of the furnaces and the gap time of each furnace should be uniform.
