Abstract

The invention discloses a production method of high-strength glass for a mobile phone screen, and relates to the technical field of production of outer mobile phone screens. The production method comprises the following steps of: (1) uniformly mixing, heating and melting raw materials for production, calendering a molten solution to a glass plate by a calendering method, (2) cutting the glass plate into a required size, and chamfering the edges, (3) putting the chamfered glass in a cleaning liquid for ultrasonic cleaning, (4) heating the cleaned glass to 400-500 DEG C, performing thermal insulation for 2-3h and then carrying out furnace cooling to a room temperature, (5) heating the annealed glass to 700-720 DEG C again, performing thermal insulation for 160-180s, blowing high-pressure cold air to the glass quickly to cool the glass to the room temperature for 120-130s, and (6) performing filming and package on the glass treated in step (5) through a film applicator, and testing the glass. The production method is simple in technology, and good in operating condition controllability, and the prepared glass is high in strength and rigidity, lower in brittleness, and good in light transmittance and corrosion resistance.

Description

Technical field: [0001] The invention relates to the technical field of mobile phone outer screen production, in particular to a production method of high-strength mobile phone screen glass. Background technique: [0002] With the gradual popularity of mobile phone color screens, the material of mobile phone screens is becoming more and more important. The color screens of mobile phones vary due to the quality of the LCD and the R&D technology. The types generally include TFT, TFD, UFB, STN and OLED. Generally speaking, the more colors that can be displayed, the more complex images can be displayed, and the layers of the picture will be richer. [0003] Glass is an amorphous solid with irregular structure (from a microscopic point of view, glass is also a liquid). Its molecules do not have long-range order in space like crystals, but have short-range order similar to liquid. Glass retains a specific shape like a solid and does not flow with gravity like a liquid. [0004]...
