Why can forged glass resist thermal shock? These processes will surprise you!
Thermal shock is a phenomenon that occurs when an object experiences rapid temperature changes, resulting in transient mechanical loads. This load is caused by the differential expansion of different parts of the object due to temperature changes. However, through a series of manufacturing processes, forged glass demonstrates excellent performance in resisting thermal shock. Want to know the secret behind this?
The Nature of Thermal Shock
Thermal shock mainly comes from sudden changes in temperature, which will cause different stresses inside the object. When this stress exceeds the tensile strength of the material, cracks will appear in the object, eventually leading to structural failure. The reason why forged glass can resist thermal shock is mainly due to its special material properties and manufacturing process.
Forged glass is able to withstand rapid changes in temperature due to the toughness and resilience of its internal structure.
Characteristics of forged glass
Forged glass is actually high-strength glass made by rapid heating and subsequent rapid cooling, a process known as "heat treatment." This process not only improves the strength of the glass, but also increases its toughness, making it more resistant to damage caused by thermal shock.
During the production process, forged glass manufacturers specifically adjust the glass's coefficient of expansion so that it expands more evenly when heated, reducing the risk of breakage caused by differences in internal stress.
Thermal shock resistance mechanism
The thermal shock resistance of wrought glass can be attributed to several important factors, including:
- Reduce temperature gradients: by adjusting the temperature gradually, rather than suddenly.
- Increase the thermal conductivity of the material: so that heat can be distributed more quickly and evenly.
- Increase material strength: Processing gives the material greater tensile strength.
- Introducing compressive stress: For example, for tempered glass, increasing surface stress can improve its ability to resist cracks.
Due to the high strength and toughness of forged glass, it can often be stabilized with a lower failure rate when subjected to thermal shock.
Thermal Shock Testing Technology
To evaluate the performance of materials after thermal shock exposure, scientists have developed various testing techniques. Among them, "pulse excitation technology" is considered to be a reliable non-destructive testing method that can be used to measure physical properties such as elastic modulus, shear modulus and Poisson's ratio of materials. These tests allowed the researchers to map how the material's properties changed after different thermal shock cycles.
Application scope of forged glass
With its superior thermal shock resistance, forged glass is widely used in various environments, including:
- Medical devices: such as surgical instruments and medication storage containers.
- High-performance building materials: such as glass curtain walls.
- Daily necessities: such as heat-resistant glass containers and kitchen utensils.
The thermal shock performance of forged glass is an important consideration, especially when developing structural design and safety standards for this type of material.
Future challenges and opportunities
Although forged glass has shown extraordinary potential for thermal shock protection, it still faces new material and technical challenges. With the continuous advancement of scientific research, new composite materials have emerged, which may have an impact on the market position of traditional forged glass.
However, as demand grows and environmental awareness grows, forged glass will continue to have a great future in technological applications and modern architecture.
Against this backdrop, can we expect future technology to unlock the potential of forged glass in more areas?
