How to balance safety and transparency for ultra-thick laminated glass at Foshan Tempered Glass Factory?

Super thick laminated glass can achieve a balance between safety and transparency through the following key points:
1. Material Selection
Advantages of laminated glass:
Laminated glass is made by sandwiching a flexible interlayer (such as PVB, SGP film) between two or more pieces of glass, which is then processed under high temperature and high pressure. Due to the good toughness, strong adhesion, and penetration resistance of the interlayer, the glass remains tightly bonded together without shattering when broken, thus providing safety protection for people and property.
At the same time, the interlayer of laminated glass can also block a portion of ultraviolet rays, providing some protection for the skin.
Choose high-quality glass raw materials:
Select glass raw materials with a lower self-explosion rate, such as Xinyi glass raw materials, and preferably ultra-white glass. Ultra-white glass not only has good transparency but also contains no impurities, resulting in an even lower self-explosion rate.
2. Process Treatment
Homogenization Treatment:
Homogenizing the glass before leaving the factory can eliminate internal stress in the glass, reduce the self-explosion rate, and thus improve safety.
Edge Treatment:
All four edges of the laminated glass should be chamfered to ensure that the edges are accurate, clean, sharp, square, and smooth, without burrs. This helps prevent glass breakage due to stress concentration and enhances overall aesthetics.
3. Design and Application
Balance between thickness and light transmittance:
The light transmittance of super laminated glass generally ranges from 82% to 91%, depending on its thickness and material. While ensuring safety, the ideal light transmittance can be achieved by optimizing glass thickness and selecting high light transmittance materials.
Choose suitable interlayer materials:
Select suitable interlayer materials based on specific application scenarios and needs. For example, SGP film has superior physical properties, including good thermal stability, light stability, adhesion, and elasticity, making it suitable for large-sized glass or special areas.
Structural Design:
When designing laminated glass, consider using a multi-layer structure or composite structure to enhance overall performance. For example, laminated glass can be combined with hollow glass to form laminated hollow glass, which retains the safety of laminated glass while improving the sound insulation and thermal insulation properties of hollow glass.
4. Installation and Maintenance
Professional Installation:
Ensure that the installation process of laminated glass meets professional standards to avoid safety hazards caused by improper installation.
Regular Inspection and Maintenance:
Regularly inspect laminated glass to promptly identify and address potential safety hazards. For example, check for cracks or damage at the glass edges, and look for delamination or bubbles in the interlayer.
In summary, through careful selection of materials, optimization of process treatment, reasonable design and application, as well as professional installation and maintenance, super thick laminated glass can achieve excellent transparency while ensuring safety.
