Tempered glass is very common in our lives, and it plays different roles in different fields. In order to ensure safety and stability, in the national standard, its production and manufacturing have strict mandatory performance requirements.
There are many physical properties of tempered glass, including flexural strength, impact resistance, self-strength, chipping characteristics, etc.
Flexural Strength:This refers to the ability of tempered glass to be not easy to crack or deform under the action of external forces, which can ensure that it can withstand external forces within a certain range without deformation, which allows it to maintain a stable structure during installation and use.
Impact Resistance:As a building material, tempered glass is often subjected to external impacts, such as wind pressure, man-made impacts, accidental collisions, etc., which requires good impact resistance to play a protective role.
Self-strength:In the national standard, the strength of tempered glass has clear regulations, and its bending strength and impact resistance must meet certain numerical requirements to ensure that the tempered glass will not break in use.
Rupture characteristics:This refers to the fact that even if tempered glass is broken, it will only form particles with a small diameter, rather than large sharp shards of glass that will not cause harm to the human body.
In the national standard, there are relevant requirements for the size, quantity and uniformity of the fragments after the tempered glass is broken, which greatly reduces the risk of personal scratches and punctures.
Thermal properties refer to the expansion coefficient, temperature resistance, temperature stability, and thermal shock properties of tempered glass.
This requires that the tempered glass must have strong high-temperature resistance after being manufactured by the tempering furnace, be able to maintain stable performance in a high-temperature environment, not break or deform, and be able to be used for a long time.
As a building material, tempered glass should maintain stable performance under various environmental conditions, resist the impact of extreme weather such as rain, snow, wind and acid rain, and play a stable role in various chemical environments.
The optical properties include the light transmittance, color, distortion and other indicators of the tempered glass.
Light transmittance refers to the degree of light transmission of glass materials, for architectural glass, good light transmittance can provide better lighting effect and improve living comfort.
Color and distortion are related to the clarity and authenticity of the glass surface, which directly affects the visual effect and user experience.
The surface of tempered glass should be flat and smooth, without bubbles, flaws or scratches, etc.; The edges are smooth, there are no burrs, cracks, etc., which guarantees both the decorative effect and its service life.
In terms of size deviation, we are required to avoid large errors as much as possible in the processing process of tempered glass, to ensure that its size meets the specified requirements, and then to ensure the use of tempered glass.
Tempered glass has corresponding mandatory performance requirements in terms of physical, chemical, optical, thermal properties, surface quality and size. The formulation of these requirements can better ensure the quality and safety of tempered glass.
Manufacturers can also provide users with toughened glass products that meet more needs, higher standards and higher quality.
