Physically Tempered Cover Glass: Robust Protection and Enhanced Durability for Electronic Devices
Physically tempered cover glass, also known as thermally tempered glass, is a type of glass that has undergone a heat treatment process to increase its strength and durability. This process, typically involving rapid heating and cooling of the glass, creates a compressive stress layer on the surface, making the glass more resistant to scratches, impact, and thermal shock.
Key Features of Physically Tempered Cover Glass:
-
Exceptional Strength: Physically tempered cover glass is typically four to five times stronger than ordinary glass, providing superior protection against breakage and scratches.
-
Optical Clarity: The heat treatment process does not alter the optical properties of the glass, maintaining its transparency and clarity.
-
Versatility: Physically tempered cover glass can be cut and shaped into various forms, making it suitable for a wide range of applications.
-
Thinner Options: Physically tempered cover glass can be produced in thinner sections compared to chemically tempered glass, allowing for sleeker and lighter devices.
Applications of Physically Tempered Cover Glass:
-
Smartphones and Tablets: Physically tempered cover glass is widely used in smartphones and tablets to protect the delicate displays from scratches, impacts, and accidental drops.
-
Architectural Applications: Physically tempered cover glass is used in various architectural applications, such as windows, doors, and partitions, due to its strength and safety features.
-
Automotive Displays: Physically tempered cover glass is increasingly being used in automotive displays due to its durability and optical clarity.
-
Appliance Panels: Home appliances, such as refrigerators and ovens, often use physically tempered cover glass for their control panels and displays.
Glass Tempering Process:
The tempering process for physically tempered cover glass involves heating the glass to a temperature of around 600-700°C and then rapidly cooling it with jets of cold air. This rapid temperature change creates a compressive stress layer on the surface, making the glass more resistant to stress and breakage
