Production method of polishing ultrathin microcrystalline glass plate

Abstract

The invention discloses a method for producing a smoothing / polishing ultra-thin mini-crystal glass plate, which includes the following steps: a. smoothing a stone plate with the same specification as the ultra-thin mini-crystal glass plate to be smoothed and polished; b. sticking an isolation layer to the surface of the stone plate; c. sticking the ultra-thin mini-crystal glass plate to the isolation layer via an adhesive, so as to enable the ultra-thin mini-crystal glass plate to be adhered to the isolation layer; and d. adopting traditional smoothing and polishing processes to smooth and polish the ultra-thin mini-crystal glass plate adhered to the isolation layer. The production method of the invention can smooth and polish the ultra-thin mini-crystal glass plate by adopting traditional smoothing and polishing processes, thereby having no requirements for updating the smoothing / polishing equipment or changing the prior smoothing and polishing processes, simple operation and strong usability.

Description

Production method of grinding and polishing ultra-thin glass-ceramic plate Technical field The invention relates to a production method of glass plates, in particular to a production method of grinding and polishing large-size ultra-thin glass-ceramic plates. Background technique The grinding and polishing process of the glass-ceramic plate is to process the large-size thin glass-ceramic blank after crystallization and sintering, and then pass the grinding and polishing process to make the product achieve the effect of flatness and high gloss. Traditional grinding and polishing are divided into manual mechanical grinding and polishing and automatic mechanical grinding and polishing. Products that are ground and polished by the above methods need to have a certain self-weight and compressive strength. Generally, large-size glass-ceramic plates with a thickness of 10mm or more use the above-mentioned grinding and polishing. Process production. Because the large-size ultra-thin g...

Problems solved by technology

Due to the light weight and poor compressive strength of the large-scale ultra-thin glass-ceramic plate with a thickness below 8mm, if the traditional grinding and polishing process is adopted, the plate will be severely damaged due to the rotation and pressure of the mill, which will cause large damage. The main reasons why ultra-thin glass-ceramic sheets cannot be normally ground and polished
