Specifically, in precleaning stage and the difference of alkaline solution used in the chemical polishing stage, this is because: precleaning The alkaline solution in stage is cleaned primarily as surface of the cleaning agent to glass baseplate, thus its require solution concentration and It is lower using temperature, do not have apparent etch effect；And the alkaline solution in chemical polishing stage is primarily as polishing fluid Micropore on glass baseplate is etched, therefore the solution concentration of its requirement and use temperature are higher, are just able to satisfy in this way The requirement of faster etching rate.

Specifically, the purpose that degreasing decontamination can be realized by the pre-clean processes to glass baseplate, make glass baseplate into Enter and keep clean surface before polishing fluid, avoid in chemical polishing process because surface it is dirty caused by etch uneven, concave-convex, fingerprint Print etc. is bad.

Preferably, after completing chemical polishing processing, the cleaning process to the glass baseplate includes pure at least once Water rinsing and wide slow moving water-removal.For the pure water, (25 DEG C) of resistivity are not less than 12M Ω CM.

Preferably, the process of the sliver processing is as follows: by wearing dustless gloves or fingerstall to the glass baseplate Artificial sliver is carried out, or sliver is carried out to the glass baseplate using the sliver fixture of profession, to obtain the glass of the smooth of the edge Glass shape product.

Preferably, when glass baseplate is sand surface glass, the glass splinter method further includes before precut processing Ink for screen printing protection processing to the non-sandblasting face of glass baseplate and the first time chemical polishing processing to glass baseplate, are plated to taking off Glass baseplate after protection ink carries out precut processing, then carries out second to the glass baseplate for completing precut processing and changes Optical polishing processing.
