The reason for choosing semi-tempered glass is mainly based on its unique performance advantages and application scenarios. The following is a detailed explanation of choosing semi-tempered glass:
1. performance advantages
Strength increase:
Semi tempered glass through high temperature and quenching treatment, the introduction of permanent stress layer on the surface of the glass, so that the mechanical strength of the glass increased several times, reaching about 2 times of ordinary float glass.
Enhanced thermal stability:
The thermal stability of semi-tempered glass is also significantly better than that of annealed glass. Ordinary glass can withstand a temperature difference of about 75°C after semi-tempered treatment, making it perform well in some environments with large temperature differences.
Security:
When the semi-tempered glass is broken, the fragments will crack radially along the crack source, and there is generally no tangential crack propagation, so the whole can still be maintained without collapse after destruction. Although semi-tempered glass does not belong to safety glass, its fragments are less likely to hurt people than ordinary glass.
Not easy to blow up:
Semi-tempered glass will not explode as easily as tempered glass, thereby reducing safety hazards during use.
2. Application Scenarios
building curtain wall and exterior window:
Semi-tempered glass is suitable for curtain walls and exterior windows in buildings, which can provide good visual effects and certain strength protection.
Made of coated glass:
Semi-tempered glass can be made into tempered coated glass, and its image distortion is better than tempered glass, which is suitable for occasions with high image quality requirements.
Reduce the risk of glass explosion:
In the door and window curtain wall, semi-tempered glass is often used as laminated glass, which can greatly reduce the risk of glass self-explosion.
Comparison of 3. with other glass
Comparison with tempered glass:
Tempered glass has higher strength and surface stress greater than 69MPa, but it is easy to explode and has poor flatness. The semi-tempered glass avoids these shortcomings, although the strength is slightly lower, but more secure and stable.
Comparison with ordinary flat glass:
Ordinary flat glass has low strength and poor thermal stability. Semi tempered glass has obvious improvement in these aspects, and is more suitable for occasions with certain requirements for strength and thermal stability.
In summary, the selection of semi-tempered glass is mainly based on its performance advantages such as improved strength, enhanced thermal stability, improved safety, and resistance to self-explosion. At the same time, semi-tempered glass has a wide range of applications in the fields of building curtain walls, exterior windows and coated glass. When choosing, trade-offs and choices should be made based on specific usage scenarios and needs.
