Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with specific embodiments, which are explanations of the present invention rather than limitations.

[0025] A chemically strengthenable alkali-containing aluminosilicate glass of the present invention, including flat glass and glass products, including SiO in mass percentage 2 52%~68%, Al 2 o 3 10%~23%,Na 2 O 8%~13%, Li 2 O 0~6%, P 2 o 5 2%~5%, ZrO 2 0~5%, ZnO 0~3%; addition of SnO can also be included 2 , by mass percent SnO 2 0.1% to 1%.

[0026] The function and specific content of each component in the above-mentioned alkali-containing aluminosilicate glass are discussed below, and the unit of content is mass percent.

[0027] SiO 2 : 52% to 68%.

[0028] SiO 2 It is a necessary component to constitute the glass skeleton. The higher the content, the better the chemical durability of the glass and the higher the mechanical strength of the glass. In addition, since SiO 2 I...

Abstract

The invention relates to an alkali-containing aluminosilicate glass and its products, strengthening method and application. In the method, the alkali-containing aluminosilicate glass is sequentially carried out twice in a salt bath of sodium nitrate and potassium nitrate at 350-450° C. Ion exchange to obtain a chemically strengthened aluminosilicate glass article; the composition of the glass includes, SiO 2 52%~68%, Al 2 o 3 10%~23%,Na 2 O 8%~13%, Li 2 O 0~6%, P 2 o 5 2%~5%, ZrO 2 0-5%, ZnO 0-3%; the surface compressive stress of the glass product after chemical strengthening is >600MPa, the compression depth of the stress layer is >50μm, the bending strength is >600MPa, and the Vickers hardness is >600MPa; in electronic devices In the application of the invention, the chemically strengthened alkali-containing aluminosilicate glass article of the present invention is included.

Description

technical field [0001] The invention relates to the technical field of flat glass manufacturing, in particular to an alkali-containing aluminosilicate glass and its product, strengthening method and application. Background technique [0002] With the development of modern display technology, a large number of flat panel display products such as LCD monitors, cash machine protection screens, touch screen information inquiry machines and media advertising players have emerged and entered our daily lives. Some electronic display products often encounter some harsh problems. The environment of use, such as sharp object scoring, in addition to the impact of man-made damage. In addition, some touch screens and handheld computers often have some dangerous operations, such as writing, scratching and impacting on the display screen with fingers, electronic pens, signature pens or even keys, which will cause damage to the screen of electronic display products and surface scratches. d...
