[0085]
[0086] The composition and physical properties of the original glass substrates used for strengthening and / or antibacterial in the present invention are shown in Table 1 below.
[0087] 【Table 1】
[0088]
[0089] The raw glass base material having the same compositional transitivity as above was evaluated and processed after strengthening or antibacterial treatment. In particular, mechanical properties such as strength were processed to be suitable for strength measurement, and strengthening by ion exchange and microstructure observation were carried out in parallel using the thus processed test piece. The detailed contents are explained below.
[0090] 1. Shape processing
[0091] Considering the determination of 3point bending strength, the original glass substrate is processed into a size of 30.73.6mm.
[0092] 2. Washing and drying
[0093] The cut original glass substrate was washed ultrasonically with ethanol and distilled water, and then washed with N...

Abstract
The present invention relates to an ion exchange method for strengthening or simultaneous antibacterial treatment of display glass and display glass strengthened or simultaneous antibacterial treatment according to the method. The step of strengthening the glass substrate for primary strengthening of the oxide film and microcracks on the surface of the glass substrate; the step of secondary strengthening of the glass substrate for ion exchange by contacting or coating potassium-based substances on at least one side of the etching of the glass substrate Ion exchange method for display glass strengthening or simultaneous antimicrobial treatment, and display glass for strengthening or simultaneous antimicrobial treatment provided by the method.
Description
technical field [0001] The present invention relates to a glass strengthening or antibacterial treatment method and the glass strengthened or antibacterial treatment by the method, more specifically, the present invention relates to at least one side comprising etching a glass substrate to eliminate oxide films and microcracks on the surface of the glass substrate (crack) a step of strengthening the glass substrate; a glass strengthening or antibacterial treatment method for the step of secondary strengthening the glass substrate by contacting or coating potassium-based substances on at least one etched side of the glass substrate to generate ion exchange , and glass that is strengthened or antimicrobially treated by its methods. [0002] In addition, on at least one side of the glass substrate, use silver or copper-based substances to generate ion exchange by solid-phase or liquid-phase coating methods, or apply silver or copper-based substances as a single component solution...
