Toughened Glass
Toughened glass, also known as tempered glass, is a type of safety glass that has been strengthened and made more durable by a special heating and cooling process. Toughened glass is used in a wide range of applications, including windows, doors, shower screens, and tabletops.
Manufacturing Process:
Toughened glass is created by heating the glass to a high temperature and then rapidly cooling it. Thermal tempering alters the physical properties of the glass, making it stronger and more resistant to breakage.
The raw glass is first cut to the desired size and shape. It is then heated to a tempering temperature of around 650°C in a tempering furnace. After reaching the proper temperature, the glass is rapidly cooled with air jets. Because of the rapid cooling process, the surface of the glass cools faster than the core, resulting in tensile stress on the surface and compressive stress in the core. This produces glass that is up to five times stronger than ordinary float glass.
Uses:
Due to its strength and durability, toughened glass is widely used in a variety of applications. Toughened glass is commonly used for the following purposes:
Windows: Toughened glass is often used in windows because it is stronger and more resistant to breakage than regular glass. It is particularly useful in high-rise buildings, where the risk of falling glass is a concern.
Doors: Toughened glass is often used in doors, particularly in areas where security is a concern. It is also commonly used in sliding doors and French doors, as it is strong enough to support the weight of the door and withstand the stresses of opening and closing.
Shower screens: Toughened glass is a popular choice for shower screens because it is resistant to breakage and is easy to clean.
Tabletops: Toughened glass is often used in tabletops, as it is strong enough to withstand the weight of heavy objects and is resistant to scratches and cracks.
Conclusion:
Toughened glass is a valuable material that is used in a variety of applications due to its strength and durability. Its manufacturing process involves heating the glass to a high temperature and then rapidly cooling it, creating a state of tensile stress on the surface and compressive stress in the core. Toughened glass is commonly used in windows, doors, shower screens, and tabletops.
