The preprocessing process of the step S10 is on the one hand to eliminate or reduce glass table caused by polishing
Layer micro-crack, on the other hand can strengthen the exchange activity of the glass and fused salt, prepare for next step toughening process.
Since the fluosilicate of indissoluble can be generated in the preprocessing process, it is attached to the surface of the glass, it may
Cause the glass surface treatment uneven or form coarse opaque hair side, therefore, the preprocessing process need by
The glass is rotated, and to ensure that the glass comes into full contact with the strong inorganic agent, and reduces the attachment of fluosilicate.Institute
After the completion of stating preprocessing process, needs to carry out ultrasonic cleaning to the glass, further remove the residual of the glass surface
Object, and it is dry in neutral environment.
The ingredient of the strong inorganic agent is mainly that the weak acid of low concentration reaches in order to control the pretreated rate
To ideal treatment effect.
S20：By after step S10 processing the obtained glass be placed in the fused salt of preset temperature, and it is described
Fused salt contact preset duration obtains tempered glass.

It is 250~400 minutes to state the duration, to ensure the abundant progress of the chemical tempering process.
The tempered glass is taken out, room temperature is slowly annealed to.
S30：Ultrasonic cleaning is carried out to the tempered glass, removes the fused salt of tempered glass surface attachment, and
The tempered glass is dried in neutral environment.
Preferably, it is more to tempered glass surface progress that water or isopropanol may be used in the ultrasonic cleaning process
Secondary washing, and the tempered glass surface is dried in a nitrogen environment.
S40：The tempered glass obtained after step S30 processing is placed in precision processing liquid and carries out precision processing
Strengthen, to remove the tempered glass due to micro-crack caused by tempering amplification and/or ion extruding.
Specifically, the condition that the precision processing is strengthened is：5~60 minutes processing times, 30~50 DEG C of temperature；At the essence
It includes following component to manage liquid：Fluoride：5~50%；Weak acid：10~50%；Amphiphilic compound：1~20%；Surplus is water.
