Tempered glass is treated with physical or chemical methods to make its internal structure tighter. Physical tempering is accomplished by rapid cooling after heating, while chemical tempering is accomplished by ion exchange at high temperatures. These methods permanently change the microstructure of the glass so that it exhibits virtually no degradation over time under normal use.
The properties of tempered glass remain stable unless exposed to high temperatures or strong chemicals.
The main characteristics of tempered glass are that it is harder, more heat-resistant, and more impact-resistant than ordinary glass. During processing, tempered glass needs to be heated to a temperature close to the softening point and then rapidly cooled to form compressive stress on the surface and tensile stress internally, thereby improving its strength and toughness.This treatment process makes tempered glass have good durability and stability, and can maintain its physical properties unchanged for a long time
As a result, tempered glass does not weaken over time and its physical properties remain stable under normal use.
The main factors affecting the stability of tempered glass products include the following aspects:
Uneven stress distribution within the tempered glass material:
Tempered glass undergoes processing steps such as rapid cooling during the manufacturing process, which results in complex stress distribution within the glass. If the stress distribution is uneven, the tempered glass will react unpredictably when struck, affecting its stability.
Surface quality and processing technology:
The surface quality of tempered glass is crucial to its stability. Any tiny imperfections, cracks or bubbles can become stress concentration points, leading to erratic rupture behavior during impact testing. In addition, improper processing technology may also lead to defects in the glass surface or internal structure, further exacerbating instability.
External environmental conditions such as temperature, humidity, etc. may also affect the stability of tempered glass. In a high-temperature environment, the stress state inside the tempered glass products may change, causing its response to external impacts to be different from that at normal temperature.
The conditions and methods of the falling ball test itself have an important impact on the results. Factors such as the mass of the sphere used during the test, drop height, and impact angle may affect the test results. Non-standard operation may cause the tempered glass to exhibit unstable performance.
The chemical composition and processing conditions of the tempered glass can also affect its stability. For example, the SiO2 and Al2O3 content in the glass, the purity of the molten salt, processing temperature and time, etc. will all affect the strength and stability of tempered glass.
Optimized manufacturing process: Ensure uniform stress distribution inside tempered glass and avoid surface defects and internal structural problems.
Control the external environment: Maintain appropriate temperature and humidity conditions during storage and use of tempered glass products.
Standardized test methods: Ensure that the conditions and methods of the falling ball test are consistent to avoid irregular operations.
Adjust chemical composition and processing conditions: Adjust the chemical composition and processing conditions of the glass according to specific needs to improve its stability and strength.
