Why does the glass steel flower basin plunge
The degree of steel, the experiment proved that when the degree of steel to 1 / cm when the number of self-explosion up to 20-25%. This shows that the greater the stress the greater the degree of taper, the greater the amount of self-explosion.
The temperature gradient of the glass in the direction of the thickness of the glass during heating or cooling is not uniform and asymmetrical. So that the tendency of blooming products, and some in the cold when the "wind burst." If the tensile zone is offset to one side of the article or offset to the surface, the tempered glass is blew.
Nickel sulfide inclusions are generally present in crystalline small spheres with a diameter of 0.1-2 mm. The appearance is metallic, these miscellaneous objects are NI3S2, NI7S6 and NI-XS, where X = 0-0.07. Only NI1-XS phase is the main cause of spontaneous baking of tempered glass.
There are stones in the glass, impurities: impurities in the glass is tempered glass weaknesses, but also stress concentration. In particular, if the stone in the tempered glass tensile area is an important factor leading to burst.
