Problems solved by technology

[0005] Therefore, the traditional use of hydrofluoric acid to corrode glass will have at least the following problems: (1) The hydrofluoric acid process is restricted by national policies, and it is difficult to approve the environmental impact assessment; (2) The investment in equipment is large. In order to prevent hydrofluoric acid leakage, hydrofluoric acid Thinning requires the use of closed negative pressure equipment; (3) The safety risk of the workshop is high and the maintenance cost is high, because hydrofluoric acid is colorless and odorless, it is necessary to install sensors at key positions in the workshop to monitor the content of hydrofluoric acid in real time; (4) Hydrofluoric acid corrosion Behind the glass is hazardous waste, and the treatment cost is high; (5) Hydrofluoric acid is a highly toxic substance, and there is a great safety risk in transportation

Abstract

The invention discloses a glass mobile phone rear cover thinning agent, compared with the prior art, the produced glass mobile phone rear cover (1) is provided with a hole site (2) for mounting a camera, and the four corners and four sides of the glass mobile phone rear cover (1) are provided with fixedly connected reinforcing ribs (3). The reinforcing rib (3) and the glass mobile phone rear cover (1) are seamlessly and fixedly connected or integrally formed, the glass mobile phone rear cover (1) comprises two or more layers of plane glass (4), a protective layer (5) is arranged on the plane glass (4), and the two or more layers of plane glass (4) are attached together through a bonding process. A series of problems existing in a glass mobile phone rear cover manufactured by a mobile phone shell rear cover manufacturing process are solved.

Description

technical field [0001] The invention relates to the field of glass mobile phone back cover manufacturing, in particular to a glass mobile phone back cover thinning agent. Background technique [0002] At present, the materials used for the back cover of the existing mobile phone are generally glass, ceramic, metal and plastic. However, with the rise of wireless charging and 4G and 5G materials, metals will shield electromagnetic waves, making wireless charging and 4G and 5G signal transmission impossible, and are gradually being phased out. Ceramics and glass have a large proportion, but ceramics are fragile, and conventional flat glass is increasingly unable to meet people's needs. Because as the curved glass of mobile phones is becoming more and more common, such as the enhancement of camera functions, a local boss has appeared on the back cover of mobile phones, and the corresponding back cover continues to meet the needs of high-definition images and lidar scanners. ...
