Do you know what kind of glass be used for acoustic office pods?
The supplier of acoustic office pods will write the material in tempered glass, but how to distinguish whether it is ordinary glass or tempered glass? Please review our words in below, it will help you to distinguish and make a good decision.
The difference between ordinary glass and tempered glass is: tempered glass is tempered by chemical or physical methods, forming compressive stress on its surface to improve the glass bearing capacity and resistance; ordinary glass is flaky or sharp when broken. When the tempered glass is broken, it is granular, and the damage is small; ordinary glass can be processed twice, but tempered glass cannot.
Glass is one of the materials that we often see and use in our daily life. It has a long history and a wide range of applications. With the development of modern technology, glass has gradually become more and more unique. Good products, so what's the difference between them?
What is ordinary glass?
Ordinary glass, also known as window glass or flat glass, is made of inorganic minerals such as quartz sand, borax, and feldspar at high temperature. It has the characteristics of light transmission, heat insulation and sound insulation, and wear resistance. , wall and interior decoration, etc.
Generally, the thickness of 2mm and 3mm is suitable for the surface of the picture frame;
5-6mm thickness is suitable for small areas of light transmission such as doors and windows;
The thickness of 7-9mm is suitable for large indoor shapes with frame protection;
9-10mm thickness is suitable for indoor large-area partitions or railings and other projects.
What is tempered glass?
Tempered glass, also known as safety glass, is a kind of prestressed glass. On the basis of ordinary glass, a compressive stress layer is formed on its surface by chemical or physical methods. When the glass is subjected to external force, the surface stress is first offset, thereby improving the overall performance of the glass. . Tempered glass is usually used in automotive, floor lamp protection, construction, interior and exterior decoration, commercial counters, showcases and other fields.
The difference between ordinary glass and tempered glass:
1. The bearing capacity of tempered glass is 3-5 times that of ordinary glass. Under the same thickness, tempered glass is less affected by the same impact force.
2. Ordinary glass is flaky when broken, with sharp edges, which is more harmful, while tempered glass is relatively uniform and granular when broken, and is relatively less harmful.
3. Tempered glass has good thermal stability and can withstand a temperature difference of 150 ° C, which is 3 times that of ordinary glass, effectively preventing thermal cracking.
4. The force on the whole piece of ordinary glass is relatively uniform, while the edge part of tempered glass is relatively weak, and the edge is more fragile when knocked.
5. Ordinary glass can be cut with a glass knife, but tempered glass cannot be cut or processed twice.
How to judge tempered glass and ordinary glass?
At first glance, ordinary glass and tempered glass seem to be difficult to distinguish, but in fact there is a big difference between the two, which can be distinguished by the following aspects:
1. 3C logo
Tempered glass must carry the 3C certification mark, while ordinary glass will not have this mark. This logo cannot be wiped off or scratched off. If the logo can be easily removed, it is definitely not real tempered glass. This is determined by the processing procedure of tempered glass: first, ordinary glass is cut according to the required size, then edged, cleaned, marked with the nationally certified 3C mark with ink, and then fired at high temperature.

2. Glass shape
Ordinary glass is very straight and unbent when viewed from the side, while tempered glass is not so flat and will be slightly curved when viewed from the side. When comparing, you can stick the ordinary glass and the tempered glass face to face, and observe whether there is a gap between the two. The side with the arc undulation is the tempered glass.
3. Glass fragments
The biggest difference between ordinary glass and tempered glass is the shape after it is broken. The large flakes and sharp corners are ordinary glass; the granular ones are tempered glass.
