Tempered glass, often referred to as safety glass, is a specialized type of glass that undergoes a distinct heat treatment process to enhance its strength and safety attributes. This thermal process involves uniformly tempering the glass to its softening temperature, typically ranging between 600 to 700 °C, depending on its thickness.

Following the heat treatment, the glass undergoes rapid cooling through the application of cold air to both surfaces. During this swift cooling phase, the outer layers of the glass cool at a faster rate than the inner layers. This differential cooling creates and locks in permanent stress within the glass, resulting from its inner layers' contraction and expansion. Consequently, tempered glass acquires significantly increased strength, typically ranging from 5 to 7 times greater than that of regular glass.

Tempered glass is widely employed across various applications due to its safety and strength characteristics. In buildings, it is commonly used in doors, windows, and ceilings to mitigate the risk of harm to individuals within the structure in the event of breakage.

Production Process of Tempered Glass

The production process of tempered glass consists of the following sequential steps:
Manufacturing Raw Glass: Initially, float glass, commonly referred to as raw glass due to its production method involving floating materials on a bath of molten tin, is manufactured in glass production facilities. Depending on the materials used, raw glass can be clear, ultra-clear, or tinted.

 

Glass Cutting: Following the production and distribution of raw glass by float glass manufacturing plants, tempered glass is manufactured by secondary glass production facilities, often called tempered glass producers. The initial stage involves cutting the raw glass into the desired dimensions according to customer specifications.2

Glass Edge Treatment: Once the cutting is complete, specialized machines are employed to smooth the sharp edges of the glass, a process known as glass edge grinding and beveling process.

Cleaning: The cut and ground glass undergo a thorough cleaning process to eliminate surface particles and contaminants. Typically, this cleaning process involves washing with water and specific cleaning agents, and tempered glass manufacturing facilities often employ specialized glass washing machines for this purpose.

Heat Treatment: The glass enters a critical phase of the process, wherein it is subjected to high temperatures, typically within the range of 600 to 700 °C.

Cooling: Following the heat treatment, the glass is rapidly cooled on both sides by a flow of air from the cooling fans of the furnace. This finalizes the tempering of the glass.

These meticulously orchestrated steps culminate in the production of tempered glass, endowing it with safety features, impact resistance, heat resistance, and other desired characteristics.

 

 

Advantages of Tempered Glass
