Toughened glass explosive rate and solution
Why tempered glass have a certain self-explosion rate?
Tempered glass self-explosion started from when the tempered glass produce.Tempered glass self-explosion can be expressed as in the absence of external direct effect of the case of automatic crushing phenomenon.
During the tempered processing, storage, transportation, installation, using and other processes can occur in the glass self-explosion.
1.According to the different cause,self-explosion can be divided into two types:
Firstly,by the visible defects in the glass cause self-explosion, such as stones, sand, bubbles, inclusions, notches, scratches, blasting, etc.
Secondly,by the nickel sulfide (NIS) Impurity and heterogeneous particles caused tempered glass self-explosion.
2, The characteristics tempered glass self-explosion is uncontrollable and the reason of tempered glass self-explosion is unclear, the main reason for the problem may be the glass containing nickel sulfide, that is, in the construction process of glass is nickel contamination, nickel and glass in the sulfide chemical reaction, resulting in rupture.nickel sulfide after the replacement of the type of difficulty.
Furthermore,the glass is most susceptible to breakage due to damage to the edge of the glass, where the tensile stress is the greatest, but shattering can also occur in the event of a hard impact in the middle of the glass pane or if the impact is concentrated (for example, striking the glass with a hardened point), be careful, don’t damage the corners.
So we should choose the top quality float glass to tempered can greatly reduce the self-explosion rate or heat soaked the tempered glass to reduce the self-explosion rate.
