Glass is not only transparent and clean, but also has high strength and hardness. It is an indispensable material in daily production and life. There are various types of glass. In addition to the more common float glass and tempered glass, there are also varieties with special properties such as hot-melt glass, laminated glass, and frosted glass. In this article, we will introduce the difference between semi-tempered glass and tempered glass.

Semi-tempered glass is processed by heat treatment process, and its strength is 1-2 times higher than that of ordinary glass, but its fragmentation state is similar to that of ordinary glass. According to the definition of safety glass, semi-tempered glass does not belong to safety glass. The stress is generally 24-52 MPa. The English translation name of semi-tempered glass is heat-strengthened glass. This standard revision refers to the standards of countries or regions such as the European Union, the United States, Japan and Australia. The standard is for the appearance quality of semi-tempered glass, Bending, surface stress, fragmentation state, thermal shock, etc. are required.

The broken state of tempered glass is small particles, so in some occasions that need to use glass to support or bear weight, tempered glass sometimes cannot achieve the desired effect. For example, the load-bearing glass ribs (glass columns) of all-glass curtain walls, lighting The glass beams on the top all use glass as the supporting structure. Once the tempered glass beams (columns) used are broken, the board surface will lose support, and the curtain wall or the lighting roof will collapse, which may cause serious consequences; another example, using double tempered glass Laminated glass is used as a load-bearing ladder. If the tempered glass on the back is broken, the whole glass will not be able to bear the load, and it is more likely to collapse. In these applications, semi-tempered glass needs to be used. Compared with tempered glass, semi-tempered glass is Tempered glass also has certain advantages in flatness, stress and bursting.

The strength of tempered glass is several times higher than that of ordinary glass, the bending strength is 3~5 times that of ordinary glass, and the impact strength is 5~10 times that of ordinary glass.

Second, it is safe to use. Its bearing capacity is increased to improve the fragile nature. Even if the tempered glass is damaged, it will be small fragments without acute angles, which will greatly reduce the damage to the human body. There is an increase of 2 to 3 times, and it can generally withstand temperature differences above 150 ° C, which has a significant effect on preventing thermal explosion.

I believe that through the introduction of the editor, you must have a certain understanding of tempered glass and semi-tempered glass. If you need it, please call our company!
