The key performance of glass equipment mainly includes optical performance, mechanical performance, thermal performance and chemical stability. These performance indicators are crucial to ensure the quality and safety of glass equipment.
Optical performance
Optical performance is one of the important indicators for evaluating the quality of glass equipment. Mainly including:
Transmittance: reflects the ability of glass to transmit light. Glass with high transmittance can make the light brighter.
Refractive index: reflects the speed of light propagation in glass, which is crucial for the design of optical instruments.
chromatic aberration: affects the chromatic aberration of light after passing through glass, which is particularly important for high-precision optical equipment.
Mechanical performance
Mechanical performance is a key indicator for evaluating the strength and durability of glass:
Compressive strength: the performance of glass when under pressure.
Tensile strength: the strength of glass when stretched.
Flexural strength: the strength of glass when bent.
Impact toughness: the durability of glass when impacted.
Thermal properties
Thermal properties mainly evaluate the heat resistance and thermal stability of glass:
Coefficient of thermal expansion: reflects the dimensional change of glass when the temperature changes.
Thermal conductivity: the ability of glass to conduct heat.
Thermal shock resistance: the performance of glass in high temperature or large temperature change environment.
Chemical stability
Chemical stability is an important indicator for evaluating the corrosion resistance and weather resistance of glass:
Water resistance: the stability of glass in water.
Acid and alkali resistance: the stability of glass in different acid and alkali environments.
Salt spray resistance: the stability of glass in salt spray environment.
