How is the heating temperature of the glass tempering furnace determined?What principles should be followed?
It is understood that the glass tempering furnace is one of the glass tempering equipment,which also melts the hot melt adhesive through the high temperature produced by the tempering furnace,and then uses the vacuum equipment to evacuate the air in it to a vacuum state.The vacuum state is to prevent the melted glue from generating bubbles,and then pressure glues the screen,silk and other materials with the glass.After cooling,the hot melt adhesive will solidify,which is the general manufacturing process of glass.
The temperature of the glass tempering furnace should be set within a reasonable range and cannot be easily adjusted.Minor adjustments in temperature will have a greater impact on glass heating efficiency.In actual production,if it is necessary to adjust the temperature of the glass out of the oven,generally by changing the heating time,a more accurate glass temperature can be obtained.
1.The stress of the glass must be completely eliminated.The residual stress in the glass cannot be completely eliminated.When the tensile stress is formed in the center of the glass at the initial stage of quenching,it is easy to cause the glass to break.
2.The glass temperature cannot cause serious deformation of the glass,so the furnace temperature cannot be set too high,and it is appropriate to be 60-100°C higher than the furnace temperature of the glass.
3.Since glass has the characteristic of selective absorption of infrared,the infrared wavelength in the glass tempering furnace of the heating furnace should be within the absorption range of the glass.According to the absorption spectrum of the glass,the maximum radiation wavelength in the furnace is about 3.0μm,and the corresponding furnace temperature is set to about 700°C.
With the increasing application of tempered glass,the development of glass tempering furnace manufacturers has also reached a new level,and the technology has become increasingly mature.Each manufacturer designs its own unique tempering furnace according to its own unique design concept.It can use the space of the site,save space and save the area and part of the site cost.Advocating energy conservation,this kind of energy-saving,time-saving and labor-saving furnaces will surely represent the development trend of glass tempering furnaces.
