Description
Technical Field
The utility model relates to the technical field of glass deep processing equipment, in particular to an air floatation heating device for ultra-thin glass tempering of a deep processing production line.
Background
The cover glass of the ultrathin double-glass assembly is required to be 2mm thick ultra-white embossed toughened glass, and has higher light transmittance as the traditional assembly, but the thickness is only 50% or 62.5% of that of the traditional cover glass. However, the drawbacks of ultra-thin glass are also evident, namely the decrease in physical strength of glass. In the toughening production process, the thinner the glass is, the larger the influence of any impurity and defect on the quality of the glass is, so that the ultrathin glass is obviously behind the common thickness of the flat glass in mechanical performance indexes such as flexural strength, surface hardness and the like.
At present, glass tempering technology is mainly divided into two major categories, namely chemical tempering and physical tempering. The strength of the chemically toughened glass is close to that of the physically reinforced glass, the chemically toughened glass is good in heat stability, good in light transmittance, high in surface strength, low in treatment temperature, free of deformation of products, free of limitation of thickness and geometric shape, simple in use equipment and easy to realize. However, compared with the physical toughened glass, the chemical toughened glass has longer production period and the fragments are similar to those of common glass. And the physical tempering generally adopts a roller way type heating mode. When the ultra-thin glass adopts a roller way type heating mode, the heating temperature is too low, the temperature gradient cannot be formed in the ultra-thin glass, and the stress cannot be formed on the surface and the inside of the glass; the heating temperature is too high, and direct contact with the roller table in the transmission process easily causes glass deformation, influences glass surface flatness, and because of heating non-uniformity, ultra-thin glass easily produces tempering stress spots.
