The History Of The Development Of Tempered Glass

Jun. 12, 2019

The development of tempered glass has gone through a long period of time, dating back to the mid-17th century. As a Drop Impact Test Equipment Exporter, let us introduce it to you. There was a King of Rhine called Robert, who had done a funny experiment. He put a drop of molten glass in the cold water and made a very hard glass. This high-strength granular glass is like a water drop, with a long, tortuous tail called "Prince Robert Little". However, when the tail of the small grain is broken and twisted, it is surprising that the entire small particle suddenly collapses suddenly and even becomes a fine powder. The above method is much like the quenching of metal, which is the quenching of glass. This quenching does not cause any change in the composition of the glass, so it is also known as physical tempered, so tempered glass is called tempered glass, also called tempered glass.

In the 1970s, tempered glass technology was widely promoted and spread throughout the world. Tempered glass was used in the fields of car, construction, aviation, electronics, etc., especially in construction and car development.

Fully tempered vacuum glass V-glass life expectancy of up to 25 years with high vacuum cavity, so that gas heat transfer can be neglected, while using high-function Low-E glass, greatly inhibiting radiation heat transfer, ensuring V glass heat transfer coefficient (U Value) as low as 0.4W/(m2·K). At the same time, V glass insulation function is 2-4 times that of insulating glass, 6-10 times that of a single glass. It can reach the requirements of heat transfer coefficient of door and window of the international forced room by independent use.
