What is the key to improving the quality of Tempered glass?

 Tempered glass is widely used with the needs of life, and its quality requirements are getting higher and higher. I believe everyone also knows that Ruben on the fifth anniversary of Guinness is the only player who failed and smashed 17 pieces in China. Netizens disputed the failure of its challenge. Is the quality of China's Tempered glass too good? Or is there a problem with the fixed method? Regardless of the result, the quality of Tempered glass is very important. Since the glass must be heated to the corresponding part of the temperature to be uniform, the difference should not be too large, so to control this data, three elements must be mastered.

1. Choose a reasonable heating time. The heating power of the tempering furnace is fixed, and the heating time is usually set at about 35-40 seconds per millimeter of glass. For example, the heating time for 6mm glass is about 6 seconds. This calculation method is suitable for ordinary flat Tempered glass with a thickness of less than 12mm. When the thickness of the glass is 12~19mm, the basic calculation method for heating time is about 40~45 seconds per 1mm of glass.

2. To achieve uniform heating, the arrangement of the glass on the placement table is also very important. The reasonable arrangement of the sheet placement is mainly to ensure the uniformity of the longitudinal and transverse loads in the electric furnace, that is, the placement of the glass sheets in each furnace must be uniform.

3. According to the load of the electric furnace, select a reasonable heating temperature and effectively control the temperature in the furnace. The heating of glass in the tempering furnace mainly includes conduction, radiation and convection. The electric furnace load mentioned here does not refer to the electric furnace, but refers to the relationship between the thickness of the glass, the heating temperature and the heating time.
