Abstract

The invention discloses an ultra-thin glass reinforcement method which is low in energy consumption and high in production efficiency, and can be operated on an automatic production line. The method comprises the steps of: putting a piece of ultra-thin glass into a vacuum reaction chamber under the conditions that the temperature is 150-250 DEG C and the air pressure is 100-1000Pa; introducing precursor gas into the vacuum reaction chamber until the air pressure of the precursor gas in the reaction chamber reaches 100-2000Pa; filling water vapor into the vacuum reaction chamber until the air pressure of the water vapor in the reaction chamber reaches 500-2000Pa; then, pumping the unreacted precursor gas and water vapor as well as gas product generated in the reaction out of the reaction chamber, enabling the pressure of the reaction chamber to reduce to 100-1000Pa, and completing an operation cycle; and finally, obtaining the reinforced ultra-thin glass after repeating 1-5 operation cycles.

Description

technical field [0001] The invention relates to a strengthening method of ultra-thin glass. Background technique [0002] The current method of strengthening glass is to use molten salt immersion method. The glass is immersed in the molten compound for strengthening. The surface of the glass reacts and absorbs with the molten salt to form a surface layer with higher strength to increase the strength of the glass. [0003] CN101348332A discloses a glass strengthening catalyst and a strengthening method. The preheated glass is immersed in a molten salt bath for strengthening. The strengthening temperature is 350-450° C. and the strengthening time is 15-35 hours. This method consumes energy and time, and is not easy to popularize and apply. [0004] CN101215105A discloses a method for strengthening the surface of lithium-aluminum-silicon glass-ceramics, which includes preparing mixed molten salt, finely grinding the lithium-aluminum-silicate glass-ceramic, putting it into the ...
