Abstract

The invention relates to a method for strengthening lithium-aluminum-silicon glass. The method comprises the following steps: selecting lithium-aluminum-silicon glass; mixing 4-10 wt% of HF, 4-7 wt% of HNO3 and 85-95 wt% of water according to the mass ratio to obtain a corrosion mixed solution; putting lithium aluminum silicon glass into the corrosive mixed solution; taking out the lithium-aluminum-silicon glass and washing the lithium-aluminum-silicon glass; preheating the lithium aluminum silicon glass; preparing a salt solution; placing the lithium-aluminum-silicon glass in the salt solution, and preserving heat for 12-36 hours at the temperature of 400-430 DEG C; taking out the lithium aluminum silicon glass, and dripping salt for 5-10 minutes; after salt dripping is completed, performing air cooling; spraying a citric acid solution on the surface of the lithium-aluminum-silicon glass, and wiping the lithium-aluminum-silicon glass; and cleaning the lithium aluminum silicon glass. The glass strength can be greatly improved, the ion exchange time is shortened, the strengthening efficiency is improved, the use time of the salt solution is prolonged, the replacement frequency of the salt solution is reduced, and the production cost is greatly reduced.

Description

technical field

[0001] The present application relates to a strengthening process, in particular to a strengthening method of lithium aluminum silicate glass. Background technique

[0002] Silicate glass is an amorphous material with excellent properties such as thermal stability, high strength, high hardness, and high light transmittance. Its products are widely used in electronic products, construction, automobiles, rail transit, aviation, aerospace and other fields. At the same time, glass is a typical brittle material with low tensile strength. There are many factors affecting the strength of glass during processing and product use, among which surface microcracks have the most obvious impact on glass strength.

[0003] In order to meet the demand for glass strength properties of products, it is particularly important to increase the strength of glass. People have developed chemical strengthening technology to improve the strength of glass. see Figure 4 ,actually Fig...
