Why check the internal stress of the glass ampoule? In the production of glass ampoule, some internal stress is inevitable. When the internal stress is concentrated to a certain extent, the glass ampoule will be easily affected by external influences. Therefore, it is necessary to test the internal stress of the glass ampoule with a professional testing instrument. Polarized stress meter This paper mainly introduces the test method for detecting the internal stress of glass ampoule using the polarized stress meter of Jinan Sanquan Zhongshi Experimental Instrument Co., Ltd. Testing equipment: The internal stress test of glass ampoule can be obtained by using the polarized light stress meter YLY-03 produced by Jinan Sanquan Zhongshi Experimental Instrument Co., Ltd. with the glass bottle thickness gauge CHY-B, which can directly obtain the optical path difference of the model ampoule. . Glass ampoules internal stress tester, polarized stress gauge should meet the following technical requirements: 1. When using a polarizing element and a protective member for observation, the brightness of the edge of the light field is not less than 120 cd/m2. 2. The polarizing element used should ensure that the polarization is not less than 99% at any point in the bright field. 3. The polarization field is not less than 85 mm. 4. A 565 nm full-wave plate (sensitive color film) and a quarter-wave plate can be placed between the polarizer and the analyzer. The slow axis of the waveplate is 90o from the plane of polarization of the polarizer. 5. The analyzer should be mounted so that it can rotate relative to the polarizer and the full wave plate or quarter wave plate, and has a measuring device with a rotation angle (the dial value is 1o). Analysis of internal stress test method for glass ampoule 1. Observe with a full wave plate, the blue streak appears in the bottle body, that is, the stress is larger (hereinafter referred to as the test point), remember this position; convert to 1/4 wave plate observation. 2. After the first step, after changing to a quarter-wave plate, adjust the analyzer to rotate slightly counterclockwise, observe the dark stripes on both sides of the test point of the bottle, and stop the rotation. 3. Then rotate the analyzer clockwise, at this time, the two dark stripes will move closer to the middle until the test point is covered, and the test point becomes zui dark. At this time, the value appearing on the instrument is the optical path difference of the sample! The above is the analysis of the internal stress test method of the glass ampoules in Sanquan Zhongshi. If you carry out the internal stress test on the glass ampoules according to this method, once the stress value in the bottle is found to be too large, the production process should be adjusted in time and an effective method should be adopted to eliminate it. Or reduce stress. Rabies Vaccine After Animal Bite Rabies is a viral infection transmitted by saliva of infected mammals, most commonly wild, terrestrial carnivores (e.g., skunks, raccoons, foxes, coyotes) or bats.rabies virus usually moves along a neural pathway and enters the CNS. After entrance into the CNS, the virus is unlikely to be affected by antirabies antibodies and encephalomyelitis usually develops and almost always is fatal. Vaccination of rabies vaccine in a timely manner is mandatory.
