Two days ago,when Xiao Zhang,a Ningbo man,was in a bath,he was injured by self-exposing tempered glass,and his reading volume has exceeded 1 billion.

　　However,as a glass deep processing company,Xiaojia immediately thought of the hazards of glass explosion after seeing this hot search.As one of the indispensable applications in modern society,why does glass explode?

　　Xiaojia asked for in-depth advice on this issue from the director of Luoyang Jinjia Fireproof Glass and the chief technical research and development director Zhao.

　　The spontaneous explosion of tempered glass can be divided into two types according to the reasons.One is the spontaneous explosion caused by the defects of the glass itself,for example,the glass has stones or impurities,bubbles and other reasons.But these situations are preventable by man.

　　There is another reason that cannot be detected and prevented,that is,the self-detonation caused by the nickel sulfide in the tempered glass.This type of self-detonation is also the most important self-detonation factor in the self-detonation of the tempered glass.

　　After the glass is tempered,compressive stress is formed on the surface layer.The inner core layer presents tensile stress,and compressive stress and tensile stress together constitute a balance body.Glass itself is a brittle material,resistant to pressure but not tensile,so most of the glass breakage is caused by tensile stress.When the nickel sulfide crystal in the tempered glass undergoes a phase change,its volume expands,and the expansion of the nickel sulfide in the tensile stress layer of the glass core causes greater tensile stress inside the tempered glass.When the tensile stress exceeds the limit that the glass itself can withstand,It will cause the tempered glass to explode.

　　Explained the reason why tempered glass exploded,then the question is,is there any safety glass that can be used safely and will not explode?

　　The answer is yes,here are a few solutions.

　　The first type is homogeneous glass.Homogeneous tempered glass refers to soda-lime-silica tempered glass that has been treated with specific process conditions.

　　The function of the tempered glass after the homogenization furnace is to completely transform the nickel sulfideαphase into the low-temperature stableβphase.The glass out of the furnace is unlikely to explode(detonate),which can effectively ensure that the tempered glass has no possibility of self-explosion.

　　The second is a new type of high borosilicate 4.0 fireproof glass product produced by our company.This glass itself does not contain nickel sulfide,so it fundamentally solves the hazard of glass self-exposure.High borosilicate 4.0 fire-resistant glass is made of original borosilicate glass(not ordinary silicate glass)with high temperature resistance,high chemical stability and high transparency through a unique processing technology.It is a fully toughened non-isolated glass.Thermal single-piece fire-resistant glass,borosilicate fire-resistant products of different thicknesses can reach fire resistance for more than 2 hours,and have been tested by a number of international authoritative organizations,but the cost is relatively high.

　　A third method may also use well-I Safety Division production laminated glass instead,it can greatly reduce the glass caused by the multiple burst hazards Laminated glass is toughened using two intermediate composite PVB film production process A kind of composite glass,this kind of glass can keep its shape unchanged when it bursts,the broken glass particles will not fall,and no sharp section will be produced,so as to avoid the occurrence of cuts and other situations.The product is in the actual use process Medium and versatile.

　　With the continuous development of science and technology,Luoyang Jinjia Fireproof Glass Co.,Ltd.is also constantly researching and developing effective fireproof glass and safety glass products that are more in line with market needs and are more beneficial to personal safety.The sky in the future is blue.Xiaojia hopes that everyone will be calm.An'an lives happily every day.
