 Reference example 1
 The 940 mm (length) × 510 mm (width) × 1.3 mm (thickness) ASAHI (Asahi Glass Blue) glass was cut by an automatic glass cutting machine model WGA-500 produced by Guangzhou Huanyu Glass Machinery Factory, and used The desktop edging machine model F-80 produced by Jiangxi Zhonghang Optical Equipment Co., Ltd. and the double-sided grinding and thinning machine model YJ2M9S-5L produced by Hunan Yujing Machinery Industry Co., Ltd. process the glass into 66.3 (length) Glass with dimensions of mm×42.8 mm (width)×0.88 mm (thickness). 300 pieces of the above glass were prepared.
 Example 1
 The present invention is used to illustrate the method for improving the strength of glass provided by the present invention.
 (1) Polishing: A Yujing polishing machine of model YJ2M9S-5L was used to polish the glass from Reference Example 1 above. The polishing includes polishing at 10 revolutions under the conditions of light pressure of 0.03 MPa and a rotation speed of 20 revolutions / minute, and then polishing at 2400 revolutions under the conditions of a medium pressure of 0.1 MPa and a rotation speed of 45 revolutions / minute. The polishing liquid is an aqueous solution purchased from Zhicheng 620 polishing powder, the weight of the water is 100 grams, the weight of the polishing powder is 35 grams, and the polishing powder contains powdered iron oxide red, tin dioxide, Alumina, barium carbonate, chalk, clay, diatomaceous earth and cerium oxide, the particle diameter of the cerium oxide is 2-8 nanometers, and the amount of the cerium oxide is ...
 Example 2
 The present invention is intended to explain the method of obtaining glass with increased strength according to the present invention.
 The glass from Reference Example 1 was strengthened according to the method of Example 1, except that:
 In step (3), the polishing includes polishing at 60 revolutions under the conditions of a medium pressure of 0.1 MPa and a rotation speed of 45 revolutions per minute, and the obtained glass size is 66.3 mm (length) × 42.8 mm (width) × 0.7992 mm (thick).
