With the emergence of float glass technology, it is possible to manufacture flat and uniform high-quality glass in large quantities, and at the same time, it also enriches the types of deep-processed glass. In addition to the commonly used high-strength tempered glass, there are also frosted glass and dimming glass that focus on privacy protection, and laminated glass and wired glass that enhance bulletproof safety performance. In this article, we will mainly introduce how to distinguish whether it is tempered glass, and explain why the floor spring glass door needs to use tempered glass.

How to tell if it is tempered glass

Tempered glass is obtained by first cutting ordinary annealed glass to the required size, then heating it to a near softening point, and then rapidly and uniformly cooling it. After tempering, uniform compressive stress is formed on the surface of the glass, while tensile stress is formed inside, which greatly improves the performance of the glass. The tensile strength is more than 3 times that of the latter, and the impact resistance is more than 5 times that of the latter.

It is also this feature that the stress characteristic has become an important symbol for identifying real and fake tempered glass, that is, tempered glass can see colored stripes on the edge of the glass through the polarizer, and when observed on the surface of the glass, you can see black and white. Alternating spots. Polarizers can be found in camera lenses or glasses. Pay attention to the adjustment of the light source when observing, so that it is easier to observe.
