Tempered glass is destructed without any external mechanical force, which called self-destruction. Currently self-destruction of tempered glass is unpredictable and inevitable. In order to reduce self- destruction as much as possible, ZNG Glass Co., Ltd. adopts international advanced technology-heat dip processing stove. Surface and edge processing of glass.
Heat-soak processing
Tempered glass is put into dipping stove and heated, and finally cooled down after heat preservation. After above processions, vulcanized nickel contained in tempered glass reaches the stable condition, and stress of interior glass tend to equilibrium, thus reduce self-destruction of tempered glass. Heat dipping can make particles or bubbles inside glass destroyed during processing. Thus self -destruction of tempered glass can be largely reduced after heat dipping treatment.
Main factor for self-destruction of tempered glass
Surface and edge processing of glass
During processing of tempered glass, vulcanized nickel crystal existed in interior glass will transfer to mini-size High-temperature alpha crystal when excess of 380℃. During cooling down, this kind of alpha crystal is frozen down not transferring to low-temperature beta crystal. With time elapsing, alpha crystal gradually transforms as beta crystal. When alpha crystal transformed to be beta crystal, its expanding size produces additional tensile stress. The double increment of stress intensity causes self -destruction of tempered glass. This is the main factor of self -destruction of tempered glass.
The other factors of self-destruction tempered glass: If the different shape glass and the drilled hole glass are easy to rupture, the installation process armored glass to support on both sides forms in the condition, the glass transporting and the installment, the maintenance process which the influence, the wind load computation is smaller than actually occurs on the other hand, deeply scratches, on the one hand to the glass surface explodes the mouth to explode and so on.
In accordance with standard DIN18516.
