Abstract

The invention belongs to the technical field of tempered glass preparation methods, and particularly relates to a homogenization processing method for tempered glass and the tempered glass. The homogenization processing method for the tempered glass comprises the following steps: S1: providing a glass original sheet, and performing the cutting, edging and toughening treatment on the glass originalsheet; S2: performing the homogenization treatment on the glass original sheet, wherein a homogenization treatment process is formed by a temperature rising stage, a constant temperature stage and atemperature reducing stage; S3: setting a temperature rising rate in the temperature rising stage as 1.5 DEG C / s to 4 DEG C / s, setting a temperature in the constant temperature stage as 240 DEG C to 300 DEG C, wherein the duration time is 1.5 h to 2.5 h, and setting a temperature reducing rate in the temperature reducing stage as 0.02 DEG C / s to 0.04 DEG C / s; and S4: moving out the glass originalsheet of which the temperature is reduced to 60 DEG C to 70 DEG C from a homogenizing furnace and continuously cooling to a room temperature. The above method is capable of, through accurately limiting homogenization treatment technological parameters, effectively controlling a temperature gradient in the homogenizing furnace, and guaranteeing the quality of the tempered glass after the homogenization treatment.

Description

technical field [0001] The invention belongs to the technical field of tempered glass preparation methods, and in particular relates to a tempered glass homogenization treatment method and tempered glass. Background technique [0002] After the tempered glass is tempered, the crystal structure of the nickel sulfide grains inside it will change over time. During the transformation process, the lattice volume will increase, and internal stress will be generated around it. When the stress builds up to a certain level, the tempered glass may self-explode. [0003] In order to prevent tempered glass from self-explosion during use, it is necessary to homogenize the tempered glass in a homogenizing furnace, and conduct a detonation test and eliminate residual nickel sulfide through the principle of hot dipping in the homogenizing furnace. However, it is often difficult to control the homogenization parameters of the tempered glass in the homogenization furnace, which will lead to ...
