▎ 摘  要

NOVELTY - Manufacturing glass having self-healing properties, comprises preparing a glass composition by mixing 55-65 pts. wt. silicon dioxide and 35-45 pts. wt. sodium oxide; adding and mixing 0.015-0.165 pts. wt. graphene flakes to 100 pts. wt. glass composition; heating the glass composition to 1400-1600 degrees C, maintaining for 30-60 minutes, and then naturally cooling it to room temperature to obtain glass; and naturally cooling the glass after being introduced into a heating furnace heated to 700-800 degrees C. USE - The glass is useful for glass windows of buildings and liquid crystals of mobile phones. ADVANTAGE - The glass has unique transparency and improved strength. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for glass manufactured as mentioned above, is dried at 100-120 degrees C for 20-26 hours, immersed in water, and an electromagnetic wave having a frequency of 1800-2400 MHz is applied for 45-75 seconds when crack occurs. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart illustrating the method for manufacturing glass having self-healing properties (Drawing includes non-English language text).
