Heat Treatment Principle
Tempered Glass with Safety Corners can fracture when its surfaces or edges are placed into tension. Under these conditions, inherent surface or edge fissures may propagate into visible cracks. The basic principle employed in the heat treating process is to create an initial condition of surface and edge compression. This condition is achieved by first heating the glass, then cooling the surfaces rapidly. This leaves the center glass thickness relatively hot compared to the surfaces. As the center thickness then cools, it forces the surfaces and edges into compression. Wind pressure, missile impact, thermal stresses, or other applied loads must first overcome this compression before there is any possibility of fracture.
Manufacturing Processes
In the "heat-treatment" process the key procedure is the application of a rapid air quench immediately upon withdrawal of hot (approx. 1200° F) glass from the "tempering furnace." The immediate and sustained application of an air quench produces the temper. As air is directed against the hot glass from arrays of fixed, reciprocation, or rotating blast nozzles, it is important to extract heat uniformly from both surfaces (uneven heat extraction may produce bow or warp) and to sustain the quench long enough to prevent reheating of the glass surfaces from the still-hot glass core. A quenched condition becomes stable when the glass is reduced to a temperature of approximately 400-600° F. There are two principal manufacturing methods for producing heat-treated glass. One process heat treats the glass in a horizontal position while the second method moves the glass through the furnace in a vertical position with each light of glass held by metal tongs.
Strength
Under wind pressure, tempered glass with safety corners is approximately four times as strong as annealed glass. It resists breakage by small missiles traveling approximately twice as fast as missiles that break the annealed glass. Tempered glass is also able to resist temperature differences (200° F - 300° F) which would cause the annealed glass to crack
FAQ
1. How to get the price of Tempered Glass with Safety Corners?
Provide details to get a quote
2. What is the heat resistance and impact resistance of tempered glass?
Generally speaking, the heat-resistant temperature of tempered glass can reach 200-250 degrees Celsius, which is more resistant to high temperatures than ordinary glass. Tempered glass is stronger and impact-resistant than regular glass. When impacted by an external force, tempered glass will break into tiny fragments instead of sharp fragments, reducing damage to the human body.
3. How to clean tempered glass?
Use a mixture of warm water and a mild detergent, or a product specifically designed for glass cleaning, to clean tempered glass surfaces. You can use a soft cloth or sponge to wipe gently, avoid using hard brushes or abrasive cleaners to avoid scratching the glass surface.
4. How long is the delivery time?
Delivery can take 3-4 weeks after receiving the deposit
