Tempered glass (Tempered glass/Reinforced glass) belongs to safety glass.Tempered glass is in fact
A kind of prestressed glass forms pressure in glass surface and answers for the intensity for improving glass usually using method chemically or physically
Power, glass bears to offset skin stress first when external force, to improve bearing capacity, reinforcing glass itself anti-wind pressure is trembled with fear
Heat, impact etc..
Production for tempered glass, most probable are not having external mechanical power problem appear to is that self-destruction phenomenon occurs
There is a phenomenon where itself to rupture in the case where effect, and the self-destruction of tempered glass is " cancer " of glass industry, there is presently no
Method solves the problems, such as this.Tempered glass generates the reason of self-destruction multiplicity, is primarily due in glass that there is monocrystalline stones
Equal heterogeneous granulars and small nickel sulfide stones etc..A part of nickel sulfide stones are with time, the variation meeting of environment after tempering
The variation that crystalline state occurs, causes volume to increase, and causes micro-crack in inside glass, and then be likely to result in the self-destruction phenomenon of glass
Occur.
Chinese invention patent CN105818494A discloses a kind of manufacturing process of tempered glass, and the technique is finally to glass
Glass carries out homogenization, actually with this destructive test, that is, creates the technique for luring the conversion of nickel sulfide lattice into
Environment, so that igniting has the tempered glass of potential risk to burst in advance, and unburstable good glass is again without the possibility of self-destruction.It should
The homogenizing step of method will can have the glass of explosion risk to reject without destroying other tempered glass well.Although the technique
Be discharged a possibility that glass is revealed again, but homogenizing step this destructive test the self-destruction rate for having had 2-3 ‰, this meeting
The cost of glass is influenced, therefore the present invention provides a kind of preparation method of high explosion-proof tempered glass of yield, this method can significantly drop
