Abstract

The invention discloses a physical full-tempering method for ultra-thin glass. The physical full-tempering method comprises the following steps: S1, heating the ultra-thin glass in tempering equipment; and S2, firstly subjecting the heated ultra-thin glass to shock cooling, and then performing conventional cooling to complete tempering of the ultra-thin glass. The shock cooling adopts a tandem type fan and an air grid for combined cooling, the air grid is internally provided with a heat exchange pipeline, and the heat exchange pipeline is filled with dry ice. The tandem type fan is used for pressurizing air, and the pressurized air impacts the surface of the ultra-thin glass through the air grid. The physical full-tempering method for the ultrathin glass, provided by the invention, is simple and low in process cost. According to the method disclosed by the invention, the ultra-thin glass can be tempered, the tempering strength is high, the glass is not easy to break, and the flatness and the mechanical strength of the tempered glass are excellent. The physical full-tempering method for the ultra-thin glass, provided by the invention, is good in tempering effect and has a very good development prospect in the field of manufacturing of the ultra-thin tempered glass.

Description

technical field [0001] The invention relates to the technical field of photovoltaic glass processing, in particular to a method for physical full tempering of ultra-thin glass. Background technique [0002] Solar energy is an inexhaustible photovoltaic clean energy. Photovoltaic power generation has the advantages of low cost, high power generation efficiency, high reliability and low carbon emissions. Among them: the core device of photovoltaic power generation is the photovoltaic module, which is composed of photovoltaic cells, glass, packaging film, welding ribbon and junction box. Among them, photovoltaic cells are the main unit of photovoltaic power generation, but photovoltaic cells need strong and durable packaging materials to maintain photovoltaic cells to meet the requirements of long-term power generation. Glass is the most important and irreplaceable material for photovoltaic modules; with the rapid development of photovoltaic power generation, the demand for ph...
