Do you know why the glass tea pot material cracks
The glass tea pot material shows the type and reason of cracks, water ripples: the water ripples on the section of the laminated glass are arc-shaped and intersect vertically with a surface. The crack is transmitted from the inside of the water ripple to the outside, and the water ripple is tightly coiled around the crack source and spreads out radially. Thus one can trace the source of the crack. The common laminated glass section is a bright appearance.
The manufacturer of glass tea pot material should use the reflective surface light source to observe, in order to see the wave pattern like the water wave pattern, pattern: the appearance of the crack on the section of the laminated glass is the appearance of a straight pattern or a curved pattern. The surface straight or curved lines on the crack section continue to expand and develop toward the parallel plane. Sometimes it also exhibits a series of straight lines, or a feather-like appearance.
This kind of pattern can generally be felt according to the contact, and the stay pattern: in the whole process of glass tea pot material inspection, sometimes on the section formed by the crack of the laminated glass, clearly visible water ripples can be seen. The information shows a very deep imprint of the start and stop cracks, or a deeper imprint when the impact crack is just beginning. Such crack imprints can also be relatively shallow, and the source of the crack can generally be traced.
The sawtooth pattern is formed due to the excessive kinetic energy that needs to be formed when the crack accelerates the development trend, and the glass tea pot material produces the edge of the mirror glass that is the source of the crack. The fine zigzag pattern is a dark gray, foggy area tightly coiled around the mirror glass at the source of the crack. An unlubricated zigzag is an area of radiating particulate matter throughout the fine zigzag surface.
The zigzag impression is formed on the surface that bears the supporting force, but it is not easy to expand and develop to the surface of the relatively laminated glass. The general display information shows the bending stress produced on the reverse side due to the shape design, the general environment of the double-layer glass, the thickness of the glass tea pot material, etc., which can be used to distinguish and accurately measure the in-situ stress size when cracking.
