The glass is typically subjected to high temperatures between 600-700 degrees Celsius, depending on the specific glass material and the desired level of tempering. At this temperature, the glass is soft and pliable, allowing the manufacturer to apply a stress pattern to it. The stress pattern is what gives the glass its strength and resilience.
After the glass has been heated to the desired temperature, the manufacturing process continues with a rapid cooling process. This is where the glass is exposed to a controlled stream of air that rapidly cools the glass down. The rapid cooling process creates a concentrated stress on the surface of the glass, which helps to balance out the tension in the center of the glass.
The rapid cooling process can be achieved through a variety of methods, including quenching in oil or rapid air cooling. The choice of method depends on the type of glass and the desired level of tempering. Once the glass has been cooled, it is inspected for any signs of defects or imperfections.
One of the key benefits of window tempering is its ability to improve durability. Tempered glass can withstand impact that would break regular glass. This makes it a popular choice for applications where safety is a concern, such as in the building industry and automotive and marine industries.
In addition to its increased strength, tempered glass also has a number of other benefits. It is capable of withstanding extreme temperature changes without shattering. It also has a greater resistance to scratching and is more less prone to degradation than regular glass.
In conclusion, window sash repair tempering is a process that involves subjecting the glass to intense heat and quick cooling to create a concentrated stress pattern on the surface. This process improves durability, making it a popular choice for safety-critical applications.
