Heat-strengthened glass that can be laminated and not self – explode

Heat-strengthened glass is also called half Toughened glass. Heat-strengthened glass is a variety between ordinary plate glass and tempered glass. It has some advantages of tempered glass, such as higher strength than ordinary float glass, which is 2 times of ordinary float glass. At the same time, it avoids the bad weaknesses of tempered glass such as poor flatness, easy self-detonation, and overall crushing once damaged. When the semi-tempered glass is damaged, it cracks radially and radially along the crack source, and generally there is no tangential crack expansion, so it can still keep the whole does not collapse after the failure.

The difference between Heat-strengthened glass and Tempered glass:
Heat-strengthened glass is annealed glass through high temperature and quenching, the surface layer of compressive stress is less than 69 MPa, so that the mechanical strength of the glass several times increased, that is, semi-tempered glass. The surface stress of semi-tempered glass is 24 ~ 69 Mpa. After its broken and ordinary glass, the product is characterized by the strength of semi-tempered glass is more than 2 times annealed glass.

Tempered glass is annealed glass through high temperature and quenching, surface formed strong compressive stress, so that the mechanical strength of glass several times increased, that is, tempered glass. The surface stress of toughened glass is 69 ~ 168 Mpa. It is characterized by broken small obtuse particles, will not cause significant harm to the human body. The strength is 4 times or more than the strength of ordinary glass. With good thermal stability, ordinary glass after tempering can withstand the temperature difference of about 180°C. The disadvantage of tempered glass is that it is easy to explode.
