Problems solved by technology

Glass lacks ductility, and the likelihood of cracking is largely dependent on the mechanical strength of the sheet itself
For thin glass, it is currently improved by coating the thin glass with an organic film or a polymer film. However, this method does not achieve the desired increase in strength. In addition, the ultra-thin glass has problems such as breakage, breakage and scratches. Occurs sometimes during transportation

preparation example Construction

[0029] The method for preparing glass described in the present disclosure may also include processing and performance testing after chemical strengthening. The processing may include slicing and / or polishing. After the glass is annealed and chemically strengthened, it may be processed and processed after the temperature drops to room temperature. Performance Testing.

[0030]According to the second aspect of the present disclosure, the chemical strengthening conditions include: the temperature may be 400-450° C., and the time may be 2-8 hours.

[0031] According to the second aspect of the present disclosure, the melting conditions include: the temperature may be 1450-1630° C., and the time may be 8-12 hours. Preferably, the melting can be carried out in a platinum-rhodium crucible, which conforms to the above-mentioned composition of the glass in the present disclosure, and the melting during the preparation process is carried out in a platinum-rhodium crucible, which is bene...

Abstract

The invention relates to a glass, and a preparation method and application thereof. The glass comprises, by weight, 56-68% of SiO2, 10-20% of Al2O3, 4-6% of B2O3, 9-15%of Na2O, 3.5-7% of MgO, 0.1-2% of RO and 0.1-3% of ZrO2, wherein the RO is CaO, SrO or BaO, or two selected from the group consisting of CaO, SrO and BaO. The preparation method of the comprises the following steps: sequentially performing mixing, fusing, homogenizing, casting molding, annealing and chemical strengthening on raw materials, wherein the composition of the raw materials allows the prepared glass to have the above composition. The glass of the invention can be applied to liquid crystal displays, camera devices, solar cell substrates and mobile phones. The glass is light in weight, high in hardness, resistant toscratches, high in breaking strength and mechanical strength, and remarkably improved in comprehensive performance.

Description

technical field [0001] The disclosure relates to glass processing technology, in particular, to a glass and its preparation method and application. Background technique [0002] Ultra-thin glass substrates are widely used in the electronic information industry due to their advantages of flexibility, light weight, transparency, and good insulation properties, such as liquid crystal displays, camera devices, solar cell substrates, mobile phones, and solar cell substrates, etc. . A major challenge in applying ultra-thin glass substrates to electronic devices lies in the handleability of thin glass sheets. Glass lacks ductility, and the likelihood of cracking is largely dependent on the mechanical strength of the sheet itself. For thin glass, it is currently improved by coating the thin glass with an organic film or a polymer film. However, this method does not achieve the desired increase in strength. In addition, the ultra-thin glass has problems such as breakage, breakage a...
