Float glass is widely used in the cover plate industry, and as part of performance requirements of terminal customers on the cover plate are continuously improved, the tin surface of the float glass needs to be distinguished for processing in different planes in part of scenes through research in the industry and specific requirements of terminals.
Demand example one is a case where a float glass is used as a large-size panel substrate, and the surface in contact with tin inevitably contains impurities as compared with the surface in contact with air in the float glass production. When chemical tempering is carried out, the surface stress of the tin surface containing impurities is different from that of the two sides of the air surface, so that the warped surface of the cover plate can be bent towards the tin surface. When the large screen is attached, the concave surface is needed for attachment due to the matching of the module and the water gel, so that the tin surface and the warping concave-convex surface need to be distinguished in the manufacturing process.
Demand example two, when float glass is used as a substrate for surface-coated AR products, due to the formulation characteristics of part of float glass, the adhesion of AR layers on the tin surface and the air surface are also different, and part of end customers may specify tin surface coating. For example, in the float glass produced by glass company, the factory technician feeds back to the terminal that the AR adhesion of the tin surface will be better than that of the air surface.
Therefore, there is a need to optimize the float glass manufacturing process, wherein the glass cover plate process requires the processes of transparent glass appearance inspection, ultrasonic cleaning and the like before the previous process is not printed, and the transparent glass cannot be marked with the tin surface, so that a technology for marking the tin surface by the transparent glass is urgently needed to improve the quality and optimize the process.
