What's the difference between tempered glass and regular glass?

1. What is tempered glass?

Tempered glass: glass after heat treatment process. It is characterized by the formation of a compressive stress layer on the glass surface, which improves the mechanical strength and thermal impact strength, and has a special fragmentation state.

Tempering process: chemical tempering, physical tempering. The common tempered glass on the market is generally physical tempered glass.

Tempered glass form:

1. Advantages and disadvantages of tempered glass

Advantages

High strength: the impact resistance of tempered glass is 3-5 times that of ordinary glass, so it has good impact resistance.

Safety: Tempered glass is uniformly small particles when broken, which is less harmful; while ordinary glass is razor-sharp when broken, with sharp edges, which is more harmful.

Thermal stability: Tempered glass has good thermal stability and can withstand temperature changes of 150℃, which is 3 times more than ordinary glass, effectively preventing thermal cracking.

Disadvantages

Cannot be reprocessed: Once the glass is tempered, it cannot be processed twice. Therefore, the glass must be processed to the required size and shape before tempering.

Self-explosion: tempered glass has the risk of self-explosion, the industry self-explosion rate of about 3‰. Tempered glass self-blowing, mainly by the glass contains nickel sulfide impurities and lead to the nickel sulfide is not visible, so can not avoid the tempered glass self-blowing. Glass such as bubbles, stones and other impurities, will also cause self-blowing.

Reduce the self-blowing rate method: homogenization, the use of ultra-white glass substrate (more affordable).

The existence of explosive points: in the handling, yardage process, to avoid bumping the four corners, because the tempered glass corners are the most fragile place, bumping is very likely to lead to glass explosion.

3. How to identify tempered glass?

Ordinary glass and tempered glass at first glance seems difficult to distinguish, but in fact there is a big difference between the two, you can distinguish between the following aspects:

3C certification mark

Ordinary glass is not safety glass, so it can not be added to the 3C mark. Toughened glass 3C mark, generally using the printing method, in the toughening process will be held in the glass mark, this mark is not wipe off, scrape off.

The state of glass fragments after breaking

In modern society, tempered glass is widely used in construction, home decoration and automotive and other fields, but its quality is good or bad we ordinary people can not be seen through the surface, so it is particularly important to choose a good reputation, strong technical force of the glass processing enterprises.

Among many glass processing enterprises, Qingdao Jinxin Glass stands out for its excellent quality, reliable safety and excellent service. From the selection of raw materials to the delivery of finished products, each process strictly follows international standards to ensure that the quality of each product meets the highest requirements.
