The detection method of stress in different glass bottles is introduced

Glass bottle barrier is good, can be used repeatedly, safe and hygienic and has good corrosion and acid corrosion resistance, so it is a more popular packaging material.
In the physical properties of glass bottles, internal stress is very important, because its presence may lead to rupture during the transport of glass bottles, affecting the use of glass bottles, so it is also very important to control the inner stress of glass bottles within a reasonable range.
the size of the internal stress in glass products is mainly determined by the de-ignition process in production, and when the process system for ad <1>ation is incorrect and unstable, the quality of de-ignition will not be guaranteed.
, the internal stress inspection can control the quality of the product, but also can be used to supervise and control the de-ignition process system.
, how can the internal stress of a glass bottle be detected? The test method of stress in different glass bottles should be introduced to note that the test products for testing stress in glass bottles should be products that have not been tested after de-ignition, and should be placed in the laboratory temperature for more than 30 minutes in advance, and gloves should be worn during inspection to avoid direct contact with the sample by hand.
In addition, but also pay attention to the following things: First, colorless test the bottom of the test: 1, will be sensitive color film removed, a quarter of the wave slice into the field of view, adjust the polarization stressor zero point, so that it is dark field of view.
2, put the sample into the field of view, from the mouth to observe the bottom, then the field of view will appear in the dark cross, if the sample stress is small, then the dark cross will be blurred.
3, rotating polarity mirror, so that the dark cross separated into two arcs moving in the opposite direction, with the outer movement of the dark area, the concave side of the arc will appear blue-gray, convex side will appear brown.
the stress value of a selected point, rotate the polarity mirror until the blue-gray point is replaced by brown.
4, rotate around the axis for the test, find out the best large stress point, rotate the polarity mirror, until the blue-gray is replaced by brown.
5, record the angle of rotation of the polarity mirror at this time, and measure the thickness of the point.
II, colorless sample sidewall test: 1, the sensitive color sheet removed, a quarter of the wave piece into the field of view, adjust the polarization stressor zero point, so that it is a dark field of view.
2, put the sample into the field of view, so that the axis of the sample and the polarization plane into 45 degrees, when the side wall appears bright and dark different areas.
3, rotate the polarity mirror until the dark area on the side wall meets, just replace the bright area completely.
4, rotate the test around the axis to determine the best large stress area.
5, recorded the bias mirror placement angle of the best large stress area, and used the stone CHY-B glass bottle wall thickness gauge in Jinan Sanquan to measure the thickness of the wall originals on both sides (record the thickness of the wall on both sides). More than
