A kind of substrate board treatment
Technical field
The present invention relates to technical field of flat panel display, relate in particular to a kind of substrate board treatment.
Background technology
The principle of chemically toughened glass is, makes the larger ion-exchange of radius in ion that in surface layer of glass, radius is less and solution, for example, by the Na in glass
+with the K in the KNO3 molten salt solution
+carry out ion-exchange, utilize the difference on the basic ion volume to form bearing stress at surface layer of glass, thus the hardness of reinforcing glass.
Chemically toughened glass in process of production, need first toughened glass roughly to be preheating in preheated tank 350 ℃ or more than, toughened glass is immersed in the KNO3 fused salt in chemical bath and carry out ion-exchange again, belong to insulating process in ion exchange process, after ion-exchange completes, be cooled to certain temperature in preheated tank.This preheating and process of cooling all need through circulating air and cooling air, to realize respectively.
Existing preheated tank inwall is provided with a recycle system and is positioned over the cage of preheated tank central interior, and the described recycle system comprises interlayer air channel, blower fan and the well heater that is arranged at inwall, and described interlayer also is provided with through hole on air channel.In described cage, parallel vertical is placed with glass, and a cover plate is stamped at its top, and described cage is positioned at outside described interlayer.During work, described blower fan output recirculating air, recirculating air is through air channel, heated by well heater or cooling, and blows out the surface of the glass to cage of flowing through, and heating or cooling described glass from described through hole.The effect of described cover plate is to guarantee the insulation of molten salt furnace in ion exchange process.
Yet, recirculating air is behind the surface of glass of flowing through, inevitably can strike the cover plate at cage top, recirculating air is diminished suddenly, cause glass to be heated from top to bottom or catch a cold inhomogeneous, affected heating and the cooling performance of recirculating air, and in glass preheating and process of cooling, the homogeneity of temperature directly has influence on the good article rate of glass.
