With the popularization and use of smart phones, users pay more and more attention to the appearance of smart phones. The appearance decoration effect of the smart phone shell and the super-hard material shell such as metal, glass and ceramic are highly concerned by the whole industry. Among the materials, the glass has the characteristics of lightness, thinness, transparency, cleanness and the like, does not have the electromagnetic shielding problem of a metal casing, is compatible with a new communication technology and a wireless charging technology, and also has the advantage of easy processing and forming, so that the glass casing has obvious competitiveness. However, how to realize a surface texture with good texture while maintaining the performance advantages of the glass housing becomes a big problem. Compared with printing, coating and other processes, the surface texture effect with good texture and high reliability can be obtained by adopting chemical etching for surface treatment.
The key point of realizing the metal texture surface of the glass shell by chemical etching is to accurately control the temperature of etching liquid so as to realize pit etching on the surface of the glass shell. However, the temperature of the glass cabinet is ambient temperature before entering the etching liquid, which is different from the temperature of the etching liquid, and the glass cabinet reaches thermal equilibrium with the etching liquid through heat exchange after entering the etching liquid, which causes the temperature of the etching liquid to change. On the other hand, because the chemical etching of the glass machine shell needs to adopt strong acids such as hydrogen fluoride and the like as etching liquid, a container for containing the etching liquid and parts entering the etching liquid groove need to adopt a teflon lining capable of resisting strong acid corrosion, and the teflon is a resin material with low thermal conductivity, so that the temperature of the etching liquid is difficult to regulate and control in time. Therefore, how to effectively control the temperature of the etching liquid becomes a technical problem which needs to be solved urgently.
Chinese patent CN105152542A, etc. adopts the formula of etching solution for adjusting chemical etching to improve the surface treatment effect of the glass housing. The method has the disadvantages that the glass shell is placed into an empty etching tank, the etching solution is injected into the etching tank, and the etching solution is emptied after the etching is finished, so that the production efficiency is limited; the etching process does not realize accurate temperature control, pit etching can not be realized on the surface of the glass shell, and the metal texture surface texture effect can not be obtained.
