Abstract

The invention discloses holes-provided cover glass stripping technology and large-size screen protective cover glass. The stripping technology comprises the following steps: stripping degraded glass with an acid stripping liquid having a pH value of 1-2, and stripping the obtained degraded glass with an alkaline stripping liquid having a pH value of 12-13. The problem that during conventional processing of a glass cover, degraded products with defects are often produced, then the degraded products requires retreatment and reprocessing to reduce the cost is overcome. The provided glass stripping technology is used for stripping holes-provided degraded glass by using acid and alkaline stripping liquids step by step. An ink layer and a coating layer on the surface of glass can be effectively stripped, and ink layers on the walls of glass through holes can be effectively stripped. After stripping, the damage made to the glass is small, the surface of the glass is not prone to be scratched, and the yield is high. The degraded glass stripped through the stripping technology can be reused as a raw glass substrate and be reprocessed, so that raw materials and cost are saved.

Description

technical field [0001] The invention relates to the technical field of glass processing, in particular to a deplating process for a cover glass with holes and a large-size screen protection cover glass. Background technique [0002] At present, some functional through holes, such as infrared sensing holes for remote sensing, will be processed on the glass screen protection cover plate due to the needs of users. The through hole of the screen protection cover usually requires high dimensional accuracy and quality. Generally, it is processed by laser cutting. The through hole after laser processing will be cleaned, and then a layer of black ink will be coated on the hole wall to hide the hole of the screen protection cover. The internal device structure, viewed from the outside, reflects the integrity of the screen protection cover, which not only hides the function of the internal structure, but also decorates the appearance. [0003] In the process of glass cover plate proc...
