Continuous homogenizing method for toughened glass

Abstract

The invention relates to a continuous homogenizing method for toughened glass. The method comprises the following steps: loading toughened glass to be homogenized through a loading area; subjecting the loaded tempered glass to the steps of a heating process, a heat preservation process and a cooling process, and completing homogenization treatment; subjecting the tempered glass after homogenization treatment to a discharging area discharging step; wherein the heating process is completed in at least one constant-temperature heating section, in the advancing process of the tempered glass with homogeneity in the constant-temperature heating section, the constant-temperature heating section enables the temperature value in a cavity to be kept at the set value through a temperature control adjusting system, and the tempered glass is heated to the needed temperature in a single-direction continuous advancing process in the constant-temperature heating section. According to the method, a furnace body of a homogenizing furnace does not need to be repeatedly heated and cooled, the tempered glass is continuously moved in a constant-temperature furnace chamber, and the heating and cooling processes are completed, so that the continuity of the homogenizing treatment process of the tempered glass can be realized, and the production efficiency is improved while the resource waste is reduced.

Description

technical field [0001] The invention belongs to the technical field of tempered glass homogenization treatment, and in particular relates to a continuous homogenization method for tempered glass. Background technique [0002] The expansion of nickel sulfide inside the tempered glass is the main reason for the self-explosion of the tempered glass. After the glass is tempered, the surface layer forms a compressive stress, and the inner core layer exhibits a tensile stress. The compressive stress and the tensile stress together form a balanced body. Glass itself is a brittle material, resistant to pressure but not tensile, so most of the breakage of glass is caused by tensile stress. When the nickel sulfide crystal in the tempered glass undergoes a phase transition, its volume expands, and the nickel sulfide in the tensile stress layer of the glass plate expands to generate greater tensile stress inside the tempered glass. When the tensile stress exceeds the limit that the gla...

Problems solved by technology

[0004] At present, the homogenization method used in the industry is to homogenize the tempered glass through a homogenization furnace, load the tempered glass to be homogenized into the homogenization furnace, and carry out three stages of heating, heat preservation and cooling of the furnace cavity The process of homogenizing the glass is completed. This process generally takes 7 to 8 hours to complete, and the production efficiency is extremely low. Moreover, the temperature of the homogenizing furnace body is repeatedly raised and lowered during the production process, which not only reduces the production efficiency, but also causes waste of resources. Therefore, the industry resists the homogeneous treatment of tempered glass and does not perform homogeneous treatment, which causes safety hazards on the site.
