Embodiment Construction

[0014] A tempering processing method for 3-6mm tempered glass, comprising the following steps:

[0015] (1) Put the 4mm flat glass into boiling salt water at 100°C for 1 hour, and the concentration of salt water is 18%;

[0016] (2) Place the glass horizontally on the roller table, and send it to the first channel tempering furnace through the roller table, and carry out heat treatment in sequence according to the interval:

[0017] The first interval: temperature 530-540°C, time 8 minutes; second interval: temperature 610-620°C, time 3 minutes;

[0018] (3) After the glass comes out of the first channel type tempering furnace, it is slowly air-cooled to below 50°C and stored for 3 hours;

[0019] (4) Place the glass horizontally on the roller table, and send it to the second channel tempering furnace through the roller table, and carry out heat treatment in sequence according to the interval:

[0020] The first interval: temperature 610-620°C, time 3 minutes; second interva...

Abstract

The invention discloses a tempering processing method for 3-6 mm tempered glass. The method comprises the following steps: boiling sheet glass in boiling salt water at the temperature of 100 DEG C for 1 to 2 hours, wherein the salt water has a concentration of 15% to 18%; horizontally placing the glass on a roller, and sending the glass to a first channel tempering furnace and a second channel tempering furnace by the roller; and carrying out heat treatments to the glass successively according to different zones. According to the method of heating in different zones, carrying out a cooling treatment in the middle procedure, and carrying out heat treatments twice, stress distribution on the surface of the glass is adjusted, flatness of the tempered glass is ensured, tempering degree of the glass surface is increased, self-destruction ratio of the glass in the cooling process is reduced, production yield of the tempered glass is improved, and performance index demands of the tempered glass are met.

Description

technical field [0001] The invention belongs to the field of glass preparation, and in particular relates to a preparation process of tempered glass. technical background [0002] Tempered glass has been widely used due to its advantages such as high mechanical strength, excellent thermal shock resistance, and good safety. Most of the existing tempered glass production processes adopt the tempering process using air as the cooling medium, so that the heated glass is subjected to chilling treatment in a short period of time through a large amount of air, thereby completing the tempering process. The existing tempered glass process leads to a high self-explosion rate. Contents of the invention [0003] The object of the present invention is to provide a tempering processing method for 3-6mm tempered glass, the glass surface stress uniformity, curvature, fragmentation, tempering degree all meet the requirements. [0004] Technical scheme of the present invention is as follo...
