SINGLE-PANEL SAFETY GLASS-ESG
ESG, also known as single-panel safety glass, is a specialized type of glass that undergoes thermal prestressing by utilizing float or appropriate decorative glass. This process involves exposing the glass to temperatures exceeding 600°C followed by rapid cooling. During this rapid cooling, the outer layer cools faster than the core, resulting in compressive stress on the surface and tensile stress in the core. This distinctive method enhances passive safety and increases the strength of the glass.
In terms of passive safety, when ESG breaks due to excessive mechanical or thermal pressure, it typically shatters into blunt-edged, loosely connected fragments, significantly reducing the risk of injury compared to conventional glass.
Passive safety category：if ESG breaks due to excess mechanical or thermal load, it usually shatters into blunt-edged(small pieces), loosely connected fragments. This characteristic significantly reduces the risk of injury compared to traditional glass breakage.
Special features: ESG also boasts several special features, including increased shock and impact resistance, high tensile bending strength, temperature shock resistance, and ball impact protection.
Temperature shock resistance: 200 K
ESG demonstrates its ability to withstand suddenly temperature changes without compromising its structura l integrity.
HEAT STRENGTHED GLASS-TVG
Partially-tempered glass, also known as TVG (Thermally Visually Tempered Glass), is produced using a similar method to that of ESG (Fully Tempered Glass). The main difference lies in the cooling process after the glass pane is heated to more than 600°C. In the case of TVG, the cooling process is slower, resulting in less tension between the surface and glass core compared to ESG.
The physical properties of TVG lie between those of normal cooled glass and ESG. When TVG is made into VSG (Laminated Safety Glass), it falls into the active, passive, or construction safety category. This is due to the remaining stability and structural capacity that exists when TVG is incorporated into VSG. The glass element made from VSG is able to withstand stress over a certain period of time in case of breakage, providing an added layer of safety and security.
Active safety category:
TVG is particularly distinguished by its increased shock and impact resistance, as well as its tensile bending strength. This makes it suitable for applications where durability and safety are paramount.
Temperature shock resistance: 100K
This means that it can withstand rapid changes in temperature without compromising its structural integrity.
Overall, TVG offers a compelling combination of strength, safety, and resilience, making it a versatile choice for a wide range of architectural and design applications. Its unique properties make it well-suited for use in environments where safety and durability are of utmost importance.
LAMINATED SAFETY GLASS-VSG
Laminated safety glass, also known as VSG (Viscoelastic Safety Glass), is a specialized product that offers enhanced safety features compared to traditional monolithic glass. VSG is created by combining two or more panels of glass with tough, highly tear-resistant polyvinyl butyral foils. (PVB film)This lamination process results in a product that provides both active and passive safety benefits.
Active safety category: VSG offers remaining stability and structural capacity even when subjected to significant stress or load. This means that the glass construction is able to bear its own weight or a defined load for a prolonged period of time, thereby reducing the risk of sudden failure or collapse.
Passive safety category： is another key feature of VSG. In the event of mechanical or thermal overload, such as impact or extreme temperature changes, the fragments of glass adhere to the intermediate layer (polyvinyl butyral) rather than shattering into dangerous shards. This reduces the risk of injury to occupants and bystanders in the vicinity of the glass.
Temperature shock resistance: VSG/float 40 K, VSG/ESG 200 K, VSG/TVG 100 K
In summary, laminated safety glass (VSG) offers a combination of active and passive safety features that make it an ideal choice for applications where safety and durability are paramount. With its ability to withstand significant loads and reduce the risk of injury in the event of breakage, VSG provides peace of mind for architects, engineers, and building occupants alike.
