Problems solved by technology

[0002] With the development of the economy, people's living standards continue to improve, and mobile phones have increasingly become a necessity in our lives. With the continuous development of science and technology, the functions of mobile phones are becoming more and more diverse. Functional requirements are becoming more and more stringent, and camera glass is an indispensable component of the camera. The quality of the camera glass directly affects the performance of taking pictures and cameras. Therefore, in order to meet people's needs, manufacturers are increasingly demanding camera glass. High, camera glass grinding is an essential process in the production process, but in the CNC (carving and grinding) stage of the existing technology, the processing of camera glass is very difficult and easy to break, and the glass cover is often broken at the CNC stage

Abstract

The invention belongs to the technical field of etching solutions, and provides an edging etching solution for camera glass and a use method of the edging etching solution. The edging etching solutionfor camera glass contains 8-12 parts of a hydrofluoric acid solution, 7-8 parts of a sulfuric acid solution and 150-200 parts of water. According to the formula system, a low-concentration hydrofluoric acid solution and a low-concentration sulfuric acid solution are mixed for use, and camera glass is not damaged while the etching effect is achieved. According to the use technology of the edging etching solution for the camera glass, the glass cannot crack, morphology structures such as cracks, sharp corners and cracks do not exist in micro pits in the surface of the glass, a rough surface with a soft micro pit curve is formed, and the edging etching solution for the camera glass has a good application prospect.
