Problems solved by technology

This patent obtains stress images through refraction principle, motion drive device, and PC, which is costly and complicated to operate, and this patent is only applicable to the detection of flat tempered glass. It is not suitable for the stress detection of curved tempered glass, especially tempered glass tableware with multi-curved surfaces. Be applicable
[0007] From the above existing technologies, it can be seen that the existing self-explosion detection technology for tempered glass products generally uses a complete set of equipment, which is costly and complicated to operate, and is only suitable for flat tempered glass, not for curved tempered glass.
And there is no relevant report on the self-explosion detection method for tempered glass tableware

Embodiment 1

[0032] Take the heart-shaped tempered glass tableware recorded in the patent CN200830282532.4 as an example to verify the accuracy of the method of the present invention, as follows:

[0033] Randomly select 10 batches of tempered glass tableware of the above shape produced in the workshop, randomly select 2,000 samples for each batch, and select a total of 20,000 samples for the experiment. The 20,000 samples were divided into two groups according to batches, and two methods were used to detect self-explosion.

[0034] Among them, 10,000 samples adopt the method of the present invention to detect self-explosion. The steps are: use an impact hammer to conduct a destructive fragment test on each tempered glass tableware sample. The sample is subjected to instantaneous impact crushing, and the tempered glass particles stick to the scotch tape after crushing, and the size of each particle is about 5cm×5cm. Select two types of tempered glass particles in the plane part and the la...

Embodiment 2

[0043] In the actual production process of toughened glass tableware, the hidden danger of self-explosion can be detected by the method of the present invention to control the quality of the delivered product. The quality control method is:

[0044] 1. When producing each batch of tempered glass tableware, conduct random sampling inspection according to the quantity of tempered glass tableware products. The sampling quantity is as follows:

[0045] Each batch of 3000 or less, the sampling quantity is 5;

[0046] Within 3001-5000 per batch, the sampling quantity is 10;

[0047] Within 5000-10000 per batch, the sampling quantity is 15;

[0048] More than 10,000 samples per batch, 30 samples;

[0049] 2. Quality control method

[0050] Use an impact hammer to test each tempered glass tableware sample for destructive fragments. First, stick a scotch tape on the surface of the sample, and use an impact hammer to break the sample instantly at a distance of 0.5 cm from the edge of...

Abstract

The invention discloses a method used for detecting tempered glass tableware spontaneous explosion hidden troubles. According to the method, the stress lines of tempered glass tableware are detected,if the stress lines are close to the center lines of cross sections of the tempered glass, the probability of spontaneous explosion is low; if the stress lines are far away from the center lines of cross sections of the tempered glass, the probability of spontaneous explosion is high. The stress lines of tempered glass formed at the interaction of internal stress and external stress are used for evaluating the probability of spontaneous explosion for the first time. In practical production, the method can be used for accurate prediction of tempered glass spontaneous explosion, and ahead quality control, so that the spontaneous explosion rate of outgoing tempered glass tableware is reduced further. Operation of the method is simple, rapid, low in cost, and high in efficiency and accurate. The method can be used for accurate prediction of tempered glass product spontaneous explosion situations; the method can be used for detecting a zone of 5cm*5cm; the application range is wider; the limitation is low; and the practicability is high.

Description

technical field [0001] The invention relates to a method for detecting the hidden danger of self-explosion of tempered glass tableware and its application, in particular to a method for detecting the hidden danger of self-explosion of non-planar and curved tempered glass tableware and its application. Background technique [0002] At present, the production method of tempered glass tableware is to heat the float glass to the softening point, so that it can be formed, cooled, and tempered at one time (this is a national invention patent, patentee: Zibo Boshan Mengyou Tempered Glass Products Factory , Patent No.: ZL200510045417.0, Inventor: Meng Deyou). As the raw material of tempered glass tableware products: float glass, due to its own production technology problems, the existence of nickel sulfide impurities cannot be completely eliminated, and the tempered glass tableware has radians and different shapes. Edge punching and other operations, if the diameter of the hole is ...
