Embodiment Construction

[0012] The embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0013] see figure 1 , is a flow chart of a glass component strengthening treatment method provided in an embodiment of the present invention. Wherein, the glass part strengthening treatment method comprises the following steps:

[0014] Step S102: forming a glass part. Forming the glass part can be achieved by means of thermoforming process, melting process or float process. Among them, the float process generally floats molten glass on the surface of molten metal (eg, tin) and allows the molten glass to cool. Fusion processes typically blend raw materials into glass compositions that are melted and conditioned to create molten glass. Molten glass is fed into the trough until the molten glass flows evenly across the sides of the trough. The glass is then rejoined or melted and drawn down to form a continuous flat sheet of glass that fo...

Abstract

The present invention relates to a method for increasing strengthening behavior of glass. The method includes making a piece of glass, annealing the glass, and then chemically strengthening the glass. Annealing the glass includes heating the glass to a first temperature and maintaining the first temperature for a predetermined first period, cooling the glass to a second temperature and maintaining the second temperature for a predetermined second period, and cooling the glass to an environmental temperature. The first temperature exceeds the annealing temperature of the glass, and the second temperature is lower than the strain point temperature of the glass.

Description

technical field [0001] The invention relates to the field of glass, in particular to a glass component strengthening treatment method capable of improving the strengthening performance of the glass component. Background technique [0002] Glass components, such as display screens and touch panels, are widely used in handheld electronic devices such as mobile phones and tablet computers. The strength level of a glass part is closely related to the possibility of failure of the glass part, for example, the lower the strength of the glass part, the easier it is to be damaged by dropping, bumping or other improper handling, and the greater the possibility of internal failure . Therefore, in order to reduce the possibility of glass components being damaged after the handheld electronic device is dropped, bumped or otherwise improperly operated, it is necessary to strengthen the glass components to enhance the strength of the glass components. However, the compressive stress of ...
