Embodiment 1

[0023] The processing method of the present chemical toughened glass comprises the following steps:

[0024] a. Configure mixed molten salt, place potassium nitrate in the molten pool and heat to 335-340 degrees, after potassium nitrate is fully dissolved, add potassium chloride powder while stirring, heat to 340-350 degrees, add acetylated di Distarch sodium powder, heat to 390-400 degrees, keep warm for 5-10 minutes, grind sepiolite into powder, add to the above mixed molten salt and stir well, maintain the temperature at 390-400 degrees;

[0025] b. Flip over, completely immerse the pre-treated glass in the above molten pool with mixed molten salt, let it stand for 1-2 minutes, then continuously flip the glass at 360 degrees in the mixed molten salt for 8-10 minutes, and move along the molten pool Continuously translate the glass back and forth in the length direction for 3-5 minutes;

[0026] c. Stand still, put the flipped glass in the above mixed molten salt for 1-2 hou...

Embodiment 2

[0042] The following uses 10 pieces of 3mm raw glass as an example:

[0043] a. Configure mixed molten salt, place 60 parts by mass of potassium nitrate in the molten pool and heat it to 340 degrees. After the potassium nitrate is fully dissolved, add 30 parts by mass of potassium chloride powder while stirring, and heat to 350 degrees. , while stirring, adding mass parts is 10 parts of distarch sodium acetylated diacid powder, the stirring time is 2 hours, heated to 400 degrees, kept warm for 5 minutes, and the mass parts are 15 parts of sepiolite ground into powder, Add to the mixed molten salt and stir well, maintaining the temperature at 400 degrees;

[0044] b. Turn over, completely immerse the pre-treated glass in the molten pool with the above-mentioned mixed molten salt, after standing for 2 minutes, turn the glass continuously at 360 degrees in the mixed molten salt for 10 minutes, and continuously Pan the glass back and forth for 5 minutes;

[0045] c. Stand still,...

Abstract

The invention provides a method for processing chemical toughened glass, and belongs to the field of glass manufacturing. The method comprises the steps of production of a mixed molten salt, overturning, standing, annealing, cleaning and drying. The mixed molten salt containing special components and the special overturning step improve the success rate of toughening, and destroy silicon-oxygen bonds in the surface of the glass to cause ion recombination in order to easily and quickly carry out ion exchange. The method for processing chemical toughened glass can improve the success rate of toughening and shorten the production time.

Description

technical field [0001] The invention belongs to the field of glass manufacturing and relates to a processing method of chemically tempered glass. Background technique [0002] Tempered glass is safety glass. Tempered glass is actually a kind of prestressed glass. In order to improve the strength of glass, chemical or physical methods are usually used to form compressive stress on the glass surface. Wind pressure, cold and heat, impact, etc. [0003] At present, the methods of preparing tempered glass are divided into physical preparation and chemical preparation. Physical tempering glass is heated to the softening temperature of the glass, and then cooled rapidly. The state of pressing, thereby enhancing the strength of the glass itself, but in the process of processing, due to the need for high temperature treatment, the glass will warp. [0004] The chemically tempered glass is mainly glass with a thickness of less than 3mm. Chemically tempered glass is to improve the s...
