Abstract

The invention discloses an ultra-thin glass chemical thinning method, and belongs to the technical field of glass processing. The method comprises the following steps: wiping non-thinned glass with the thickness of 2-2.1 mm by using a cleaning solution, removing surface grease, performing washing with clear water, and performing natural air-drying; then, placing the glass which is not thinned on an operation table, putting the glass on a base plate, packing paper, covering an acid-proof film, and removing residual glue on four sides; and finally, putting the acidic etching liquid into a water jet cutter, then carrying out feeding and thinning treatment on the non-thinned glass attached with the acid-proof film from a feeding hole of the water jet cutter, and enabling the non-thinned glass to continuously pass through seven thinning notches to obtain the ultra-thin glass. The ultra-thin glass prepared by the method is uniform in thickness, and the deviation can be within + / -0.005 mm. In addition, batch production can be realized, and glass with maximum area of 550 x 650 mm can be manufactured; and the requirements of customers can be met by adjusting the parameters of the water jet to machine products of different specifications, the cost is low, and the yield is higher than that of raw material production.

Description

technical field [0001] The invention relates to the technical field of glass processing, in particular to a chemical thinning method for ultra-thin glass. Background technique [0002] With the increasing maturity of display technology, the thinning and thinning of display devices has become a mainstream development trend today, and one of the directions is to use ultra-thin glass as the substrate of the display panel. Therefore, the glass thinning process is an important link to realize the thinning of the display device. [0003] At present, chemical etching thinning is the main thinning method of glass. Through the chemical reaction between etching acid solution and glass components, the glass substrate is thinned to the thickness required by the process. However, the existing manufacturing costs are high, the thinning thickness control is not good, the deviation is large, and the product surface yield is low. After thinning, polishing production is required, and the pro...
