Tempered glass (heating about 680~750 °C) is a rapid cooling method that destroys the original molecules of the glass so that the compressive stress is distributed on the glass surface, and the tensile stress is in the center layer. Due to the strong equal compressive stress, the tensile stress generated by the external pressure is offset by the strong compressive stress of the glass, which increases the safety of the glass. When the external force exceeds the tension inside it, the tension will be out of balance and smashed, becoming countless fine particles. The semi-tempered glass (heating about 600 °C) achieves the purpose with a gentle cooling curve. Relatively speaking, its strength is naturally less than that obtained by the violent method of rapid cooling. Therefore, the above two glasses will exhibit different strength performance, mainly in the control of cooling time. In addition, too thick glass cannot be semi-tempered (the thickness is about 10mm), but tempered glass is not limited.
➊Lighting glass: It needs to be dustproof and waterproof. It can be used outdoors. When the light source is lit, it can withstand sudden rain or snow without breaking.
➋Glass glass: mechanical equipment for observation, processing equipment or laser-processed window glass, which can protect human eyes and body, avoid damage, and can be shielded against ultraviolet rays, infrared rays, lasers or specific harmful light. film;
Mirror glass: Vacuum equipment that needs to be observed, such as vacuum furnaces, vacuum coating machines, etc., can observe changes in the furnace and can withstand high vacuum pressure.
➍Building: electric door, escalator, bathroom door, floor and window, window, compartment door and window, building door room。
➎ Furniture: table, coffee table, bookcase, audio door leaf.
➏ Appliances: microwave, oven, solar glass, aquarium.
➐ Vehicles: cars, trains, ships, aviation.
