Can be regarded as a real safety glass tempered glass |
Nickel sulfide crystals occur in the changes in tensile stress, tempered glass, crystal blew. The transformation of the time indefinitely, the glass blew room temperature, the complete uncertainty, and detonated treatment to reduce the probability of blew low.
Undergo a rigorous homogenization, the glass blew the probability will greatly reduce the 10,000 m2 m glass blew a probability of only 1% within one year. Tempered glass, this time can be regarded as a real safety glass.
The phase transition from the β phase α, the diameter of 2-4% of the crystal volume caused by changes in the nickel sulfide crystal glass, nickel sulfide crystals sounded an average of about 0.2 mm. The reasons for tempered glass factory in Qingdao, glass manufacturing process, the glass blew a mixture of nickel-containing impurities, these impurities in the glass melting process, the use of each other the formation of sulfide melt extraction of raw materials or refractory nickel crystal. More than 380 ℃ high temperature α phase at room temperature β-phase nickel sulfide crystals.
Glass in the wind, Qingdao tempered glass factory glass is cooled to room temperature cooling effect is very fast cooling rate, the structure is completely fixed, nickel sulfide crystals have the opportunity to the β-conversion of low temperature, high-temperature α phase. The original glass, and by a slow annealing process of the formation of nickel sulfide crystals does not influence the strength of the glass. However, when the case of glass, steel processing, very different. Tempered glass is used in the quenching process.
Way to solve the glass blew Heat Soak: tempered glass re-heated to 280-300 ° C, then heated for 2-4 hours, conditional blew tempered glass burst in this process. The tempered glass tempered glass to detonate processing or tempered glass, hot-dip processing. Nickel sulfide crystals occur in the changes in tensile stress, tempered glass, crystal blew. Due to time indefinite crystal transformation and detonated the tempered glass factory in Qingdao management to reduce blew the probability is low, the room temperature, the glass blew is uncertain. |
