Abstract

The invention aims to provide a rapid ion-enhanced method for soda-lime-silica glass and soda-lime-silica ion-enhanced glass, belongs to the technical field of glass enhanced treatment and in particular relates to a rapid ion-enhanced method for soda-lime-silica glass. The method comprises the following steps: providing a soda-lime-silica glass product, and cleaning with deionized water; providingan aqueous solution comprising an ion-exchange material, and uniformly spraying the aqueous solution into a mold cavity; placing the cleaned glass product inside the mold cavity; placing the mold with the built-in glass product on an induction heater, and performing ion exchange enhancement; stopping heating, taking the glass product out of the mold, naturally cooling in air, and drying after ultrasonic cleaning, thereby obtaining the soda-lime-silica glass product subjected to ion exchange enhancement. According to the method disclosed by the invention, the ion-enhanced time of the soda-lime-silica glass is greatly shortened, and ions that are difficult in ion exchange, such as Ca<2+>, Al<3+> and the like, can be exchanged, so that the production efficiency is improved, the cost and energy consumption are reduced, and a new path is provided for improving the strength of the soda-lime-silica glass.

Description

technical field

[0001] The invention belongs to the technical field of glass strengthening treatment, and relates to a rapid ion strengthening method of soda-lime-silica glass and soda-lime-silicon ion-strengthened glass. Background technique

[0002] Food-grade container glass is mainly soda-lime-silica glass. With the improvement of people's living standards, the requirements for the performance of soda-lime-silica glass are getting higher and higher. High-strength soda-lime-silica glass can be used in high-end glass products. Ion exchange is an effective method to improve the strength of soda-lime-silica glass. The enhancement mechanism is to use the characteristics of ion migration and diffusion on the glass surface to change the composition of the glass surface layer, thereby increasing the strength of the glass.

[0003] Nowadays, ion exchange enhancement is usually performed by placing the original glass sheet in a molten pool of a specific molten salt for ion exchan...
