High-precision temperature control device and method for metal texture surface treatment of glass shell

Abstract

The invention relates to a high-precision temperature control device and method for metal texture surface treatment of a glass shell. The high-precision temperature control device is used for adjusting the temperature of etching liquid in a liquid tank for carrying out metal texture surface treatment on the glass shell. After a material basket is immersed into the liquid tank, the processes of cooling, low-temperature constant-temperature treatment and heating are sequentially carried out; a sinking pipeline and an annularly distributed pipeline communicate a cold cylinder with a hot cylinder,so that a circulating medium can flow between the cold cylinder and the hot cylinder; part of the sinking pipeline and part of the annularly-distributed pipeline are arranged in the liquid tank, andthe outer wall of the sinking pipeline makes contact with the etching liquid, so that the circulating medium in the sinking pipeline and the annularly-distributed pipeline can exchange heat with the etching liquid, the etching liquid is cooled when the circulating medium flows from the cold cylinder to the hot cylinder, and the etching liquid is heated when the circulating medium flows from the hot cylinder to the cold cylinder.

Description

technical field [0001] The invention relates to the field of new materials, in particular to a high-precision temperature control device and method for metal texture surface treatment of glass cabinets. Background technique [0002] With the continuous development of smart phones, mobile phone users put forward higher and higher new requirements for the appearance and texture of mobile phones. Compared with the metal case, the glass case not only has a crystal clear appearance, but also is compatible with new application technologies such as wireless charging, and has a very good user experience. However, the disadvantage of the glass casing is that the unevenness of the surface texture is not enough, and it is difficult to realize the metallic texture of the metal casing. Using low-temperature chemical etching, the ideal metal texture surface texture of the glass case can be obtained. However, the etching process of low-temperature chemical etching requires the glass casi...
