Glass panel frosting process

Abstract

The invention provides a glass panel frosting process. Firstly, an acid-resistant protective ink layer is arranged on a Logo pattern on the front surface of a panel, and an acid / alkali-resistant protective ink layer is arranged on the back surface of the panel; then, chemical frosting treatment is carried out on other areas, which are not provided with the protective layer, on the front surface ofthe panel; then the acid-resistant protective ink layer on the Logo pattern is removed by using an alkaline deplating solution, and chemical polishing treatment is carried out on the front surface ofthe whole panel including the Logo pattern and the frosted region; and finally, the acid / alkali-resistant protective ink layer on the back surface of the panel is removed by using a strong acidic deplating solution. The frosting process provided by the invention is simple to operate, the ink layers with different properties are adopted to protect the back surface and the Logo pattern on the front surface of the panel, and the two kinds of protective ink are deplated step by step, so that the back surface of the panel has no scratch defect, meanwhile, there is no hand feel of scratch betweenthe frosted surface of the front surface of the panel and the polished surface of the Logo pattern, and the product quality is improved.

Description

technical field [0001] The invention relates to the technical field of production of shells of electronic products, in particular to a glass panel frosting process for glass panels on electronic products. Background technique [0002] In recent years, in addition to conventional materials such as ceramics, metals, and plastics, glass is also widely used as a production material for panels. Among them, electronic-grade frosted glass is a product with good anti-glare effect and good touch feel. It is increasingly favored by customers. In the actual production process, in order to obtain better visual effects, different processing techniques are usually used for different areas of the front of the panel (the back of the panel faces the inside of the mobile phone, and no additional treatment is usually required), among which, the logo pattern surface is made into The glossy surface, and the rest of the surface is made into a frosted surface, which makes the Logo pattern have a ...

AI Technical Summary

Problems solved by technology

Specifically, since the protective ink arranged on the back of the panel and the logo pattern on the front of the panel is the same ink, the two must be stripped synchronously during deplating. Therefore, for the first method route, since the frosted surface is polished The surface of the logo pattern is not polished, so the surface of the logo pattern will be higher than the frosted surface. The height difference between the two will cause a scratching feeling similar to steps when touched by human hands. According to the different needs of customers for polishing, there are The height of the steps on the panel products can even reach 10-30um, which seriously affects the comfort of the mobile phone; for the second method, although the problem of scratching is avoided, the protective ink on the back of the panel is also faded in advance. When polishing, it will cause scratches on the back of the panel, affecting product quality and appearance
