Tempered glass is a common safety glass material. Because of its excellent characteristics, it can be widely used in many fields. Tempered glass not only has many advantages, but also has some disadvantages. This article discusses some advantages and disadvantages of tempered glass to help you better understand tempered glass.
The advantages of tempered glass
High strength
The strength of tempered glass is 4-5 times that of ordinary glass. So it is much stronger than ordinary glass in terms of safety. Can be very good impact resistance, resistance to scratches. Tempered glass is made by rapid cooling after high temperature. Its internal structures pull on each other, increasing the internal stress. So it is very strong in carrying capacity.
Security
Tempered glass is called safety glass because it forms small particles at obtuse angles when broken. Unlike other ordinary glass, it doesn't break into sharp screaming shards. Therefore, in many places with high safety requirements, tempered glass has become the first choice. It can reduce the damage caused to the human body when the glass is broken.
Heat resistance
Tempered glass also has high heat resistance because of its production process. Like ordinary glass, it can withstand temperature changes of only 70-100 degrees Celsius. But tempered glass can withstand temperature changes of 200-300 degrees Celsius. It can be said that tempered glass is more widely adapted to the environment. The application in high temperature and heat resistant environment has obvious advantages over other glass.
Aesthetic
The beauty of tempered glass is different from that of stained glass. The tempered glass design is simple and clean. But it's also because it's smooth and transparent. So it is a good expression of modern aesthetics. Most modern architectural designs pursue simplicity and cleanliness, so tempered glass is very suitable. If we add some diversified processing methods, it can also be used in decorative applications.
Environmental performance
Apart from some of the advantages mentioned above. Tempered glass also has the small advantage that it is an environmentally friendly material. It can be recycled without causing pollution to the environment. In the current wave of low-carbon environmental protection, tempered glass is also widely promoted and used.
The disadvantages of tempered glass
Non-processability
You should know that once the tempered glass is formed, it can not be processed again. No cutting, no drilling. These processing methods will destroy the characteristics of the tempered glass itself. At the same time, it is easy to cause the tempered glass to break.
So before we have to deal with tempered glass, we must first think about how to design. Your cutting, drilling, and edging must all be done before the tempering process. The size and shape of the user's needs should be determined in advance. Avoid creating waste and unnecessary costs.
Self-detonation risk
There is a phenomenon that tempered glass may break without obvious external force. This is because the tempered glass itself is very strong, but its internal stress may not be uniform.
In the case of uneven internal stress, they pull on each other. There may be a concentration of force inside the glass. Under the action of time, the tempered glass may self-explode.
It is also possible that during the tempering process, small nickel sulfide particles may remain in the glass. These particles cannot withstand temperature changes. Under long-term stress, they may cause the glass to self-explode.
Higher cost
The production process of tempered glass is very strict and fine. To high temperature and cooling, the production cost is higher than that of ordinary glass. Therefore, although the characteristics of tempered glass are excellent, it may also be limited in the degree of application.
In general, in the large-scale demand for glass materials, most architects will consider the overall cost. The use of tempered glass in large areas may increase costs.
Heavier weight
The density of tempered glass is actually the same as that of ordinary glass. However, the thickness of tempered glass is relatively large, so the weight is heavier. Some applications that require lightweight may be limited.
