When the toughened glass is subjected to external force, the toughened glass is not easy to damage due to high strength of the glass, even if the toughened glass is damaged, fragments of the toughened glass are honeycomb obtuse-angle small particles, no cutting edge exists, people cannot be injured, the safety effect can be achieved, and the toughened glass is mainly used for rear shelves and side windows of cars and buses. The front and back glass plates are fired at different process and temperature before being treated, and black pigment is printed on the glass plate before firing. The black edge block of the front bumper of the automobile mainly plays roles in decoration, visible light prevention and ultraviolet ray prevention, and needs black shielding force, corrosion resistance and the like; besides the requirements, the automobile rear windshield needs to print the silver paste conductive circuit after printing the black ink, so that the conductive performance and the black shielding force are kept unchanged to the greatest extent after printing the silver paste.
