Which factors could cause the tempered glass broken after installation
Tempered glass is designed to be strong and shatter-resistant, but it can still break under certain conditions or due to various factors, especially after installation. Here are some factors that can cause tempered glass to break after installation:
1. Edge Damage: Tempered glass is more vulnerable at its edges, where it is weaker due to the tempering process. Any chips, nicks, or damage to the edges during or after installation can create stress points that may cause the glass to break.
2. Surface Damage: Scratches, gouges, or impact damage to the surface of the glass can weaken it and make it more prone to breakage.
3. Thermal Stress: One of the most common reasons for tempered glass breakage is thermal stress. This occurs when there is a significant difference in temperature between different areas of the glass. For example, direct sunlight on part of the glass while another part is in the shade can create thermal stress. Thermal stress can also result from using hot water on a cold glass surface or exposure to rapid temperature changes.
4. Improper Installation: If the glass is not installed properly, with uneven pressure, excessive torque, or inadequate support, it can create stress on the glass and lead to breakage. Proper installation techniques are crucial to minimize this risk.
5. Manufacturing Defects: Although tempered glass is generally strong and consistent, there can be rare instances of manufacturing defects that weaken the glass. These defects may not be immediately apparent but can lead to breakage over time.
6. Impact: A significant impact, such as a hard blow or collision with a heavy object, can cause tempered glass to break. Even though it's designed to be more impact-resistant than regular glass, it can still shatter upon extreme force.
7. Inadequate Frame or Support: If the glass is not adequately supported within its frame, it may experience bending or flexing, which can lead to breakage over time. Ensure that the frame and support system are designed to handle the glass's weight and size.
8. Twisting or Bending: If the glass is installed with uneven pressure or twisted during the installation process, it can create stress points that may lead to breakage.
9. Inadequate Clearances: If tempered glass is installed in a frame or structure without sufficient clearance or room for expansion and contraction due to temperature changes, it may break when it attempts to expand or contract.
10. Nickel Sulfide Inclusions: Rarely, tempered glass may contain microscopic nickel sulfide inclusions that can cause spontaneous breakage. This type of breakage may occur months or even years after installation.
Proper handling, installation, and maintenance of tempered glass can help minimize the risk of breakage. It's essential to follow industry standards and guidelines when using tempered glass in various applications to ensure its long-term durability and safety.
