Tempered glass is annealed glass to be processed into require size shape,, carry out again the specific glass that obtains after quenching is processed, thereby make the surface of glass form powerful compressive stress to the temperature near softening point through high-temperature heating, the powerful tension stress of inner formation, physical strength is multiplied.Fragment is radial diffusion behind the toughened glass crushing, without sharp corners, does not hurt sb.'s feelings, and belongs to safety glass.
Along with the development of society, glass is used more and more extensive in people's routine work and life, and for the security and the intensity that improve glass, tempered glass generally is used in the goods such as vehicle glass, building curtain wall.But because glass itself is a kind of hard brittle material, in fracture process, almost without any plastic deformation, destroy sudden and catastrophic often.
The explosion of tempered glass except artificial active is knocked in a lot of situations all is because the tempered glass explosion that the self-destruction of tempered glass causes.Toughened glass self-explosion is without the Fragmentation Phenomena that occurs under the applied external force, glass fragment centered by the self-destruction starting point to around be radial diffusion, can have two larger fragments and present " butterfly macules " feature revealing the starting point place.Self-destruction can not be avoided fully for tempered glass, also is absence of aura, and the probability of its generation is usually 3 ‰.
The time of toughened glass self-explosion does not have determinacy, may be fresh baked, the 1-2 that also may dispatch from the factory just reveals, or even the rear 4-5 that dispatches from the factory just reveals.In recent years, because the generally application, the particularly surge of the use amount on vehicle glass and glass curtain wall of tempered glass, under 3 ‰ self-destruction rate background, the bursting accident frequent occurrence of tempered glass.So judge, lose the aspects such as setting loss the party responsible, the demand that society identifies for the rupture reasons of tempered glass also constantly increases.
In general the reason that causes toughened glass crushing of may disequilibrating has external cause and internal cause.External cause comprises undue load, collision, unsuitable gap and the infringement of limit section etc.; Internal cause comprises: 1. tempered glass limit section manufacturing deficiency, wedge angle, punching quit a post and thus leave it vacant equal stress concentrated area stress are excessive, 2. the tempered glass internal stress is excessive, 3. there is nickel sulphide inclusions in tempered glass inside, internal cause is 1. 2. owing to technology controlling and process reason in the tempered glass process causes, and the internal cause 3. factor of nickel sulfide is to produce in former sheet glass manufacturing process.
3. find after deliberation, after having got rid of external cause, in the immanent cause of tempered glass explosion, be that tempered glass inside exists the situation of nickel sulphide inclusions the most general with internal cause especially.This kind situation tempered glass " cancer " that in the industry cycle is otherwise known as.
At present domestic reason for the tempered glass explosion identifies that authentication method or the standard of corresponding system science are not identified, so whether the explosion of how to confirm tempered glass is revealed and become this field problem demanding prompt solution.
?
Summary of the invention
There is no the method for corresponding system science in the prior art or whether reason that standard is carried out the tempered glass explosion is the problem that self-destruction is determined for solving, the invention provides following technical scheme:
A kind of authentication method of toughened glass self-explosion is characterized in that: the method may further comprise the steps:
A, the original appearance inspection is carried out at tempered glass explosion scene, confirmed the position of tempered glass explosion breach, the direction of breach cracking;
B, the crackle size of the crack shape of tempered glass is carried out appearance observe;
C, under optical microscope, the cracking breach is carried out optical observation, seek the breach place and whether have anomalies;
Behind D, process steps A, B, the C observation analysis, do not find that external force collision causes the feature of explosion, and find to exist the self-destruction calculus, under scanning electron microscope, carrying out the stone composition element by X ray characteristic particle energy spectrometer confirms, if self-destruction point calculus contains S element and Ni element, can confirm the former of tempered glass explosion because self-destruction.
As a preferred embodiment of the present invention, among the described step B, if find the pattern of the figure of eight or butterfly's wing shape, then this is characterized as the feature of toughened glass self-explosion.
As another kind of preferred version of the present invention, among the described step B, if find that the texture that breaks of tempered glass is even, then this is characterized as the feature of toughened glass self-explosion.
The present invention has the following advantages: whether the inventive method is that the evaluation of revealing was divided into for two steps on the whole for the tempered glass explosion, the first step determines that the reason of explosion is external cause or internal cause, second step, determine to carry out analysis of causes checking after the internal cause, the inventive method step is clear, simple, can effectively determine the self-destruction of tempered glass, for the self-destruction Analysis deterrmination of tempered glass provides system, science, unified method.
