Summary of the invention
The technical problem to be solved in the present invention is, for the deficiencies in the prior art, provides a kind of glass reinforced working method of extraordinary high alumina that can improve glass transparent degree, high-temperature capability and ultimate compression strength.
For solving the problems of the technologies described above, the present invention adopts following technical scheme.
The glass reinforced working method of a kind of extraordinary high alumina, the method comprises the steps: step S1, and original sheet glass is provided, and this original sheet glass is carried out to pre-treatment; Step S2, is placed in acid solution by glass and carries out cleanup acid treatment, eliminates the tiny crack of glass surface by acid corrosion; Step S3, ultrasonic glass cleaning; Step S4, is placed in glass in fused potassium nitrate groove, in described fused potassium nitrate groove, is placed with fused salt material, utilizes the sodium ion in the potassium ion displacement glass in fused salt material.
Preferably, in described step S1, the preprocessing process of original sheet glass is comprised to selected, cutting and edging finishing polish.
Preferably, by volume part meter, described acid solution comprises: 10 parts～30 parts, hydrofluoric acid; 1 part～5 parts, sulfuric acid; 65 parts～90 parts of pure water.
Preferably, the described cleanup acid treatment time is 5 seconds～200 seconds.
