The test process of the drug vacuum bottle sealing detector

The test process of the drug vacuum bottle sealing tester sealing tester: with the increasing wealth of material life, people's requirements for commodity packaging are not only to protect the goods from damage and aesthetic requirements At the same time, it is also required to have a variety of functions, such as preservation, antisepsis, antibacterial, anti-counterfeiting, extended shelf life and so on Now let's focus on one of the main performance indicators of Zui, which affects the preservation, antisepsis, antibacterial, anti-counterfeiting and prolonging the shelf life of the packaging - the "tightness" of the packaging The sealing tester designed by Jinan jingji It is to determine the sealing performance of the sample by vacuuming the vacuum chamber to produce the internal and external pressure difference of the sample immersed in water and observing the gas escaping from the sample; it is to determine the sealing performance of the sample by vacuuming the vacuum chamber to produce the internal and external pressure difference of the sample and observing the expansion of the sample and the recovery of the sample shape after the vacuum is released The sealing tester is applicable to the sealing test of packaging bags, bottles, tubes, cans, boxes, etc in food, pharmaceutical, medical equipment, daily chemical, automobile, electronic components, stationery and other industries The sealing tester can also test the sealing performance of the test piece after the drop and pressure test During the test process of the sealing tester, 1 inject clear water into the vacuum chamber, the height of which is higher than the bottom laminate surface on the cylinder head, and put the test piece At this time, the distance between the top surface of the test piece and the water surface shall not be lower than 25 mm To ensure the sealing effect, sprinkle a small amount of water on the sealing ring 2 Cover the sealing cover of the vacuum chamber, turn the switch on the tester to the open position, adjust the control and adjustment knob of the tester (see above for the adjustment method), observe the vacuum pressure gauge, and adjust the pressure to the stable value required by the test 3 to reach the required pressure, turn the switch of the tester to the off position, keep the vacuum, the timer starts to count, observe the sample, and reach the holding time Note: the adjusted vacuum value is determined according to the characteristics of the sample (such as the packaging materials used, sealing conditions, etc.) or the provisions of relevant product standards 4 The leakage of the sample during the vacuumizing process and the vacuum maintaining period after reaching the preset vacuum degree depends on whether there are continuous bubbles A single isolated bubble is generally not considered a sample leak 5 when the pressure holding time is reached, turn the switch on the instrument to the off position, eliminate the vacuum, open the sealing cover, take out the test sample, wipe the water on its surface, and observe the damage result on the surface of the packaging bag Product name of sealing tester: negative pressure sealing tester, sealing tester, sealing tester, sealing tester, sealing tester, negative pressure sealing tester, packaging sealing tester, drug packaging sealing tester, compound bag sealing tester, aluminum plastic blister sealing tester, cosmetic bottle cover sealing tester, drug compound film tape sealing tester, oral liquid bottle sealing tester, Label of Jinan Jingji Testing Instrument Co., Ltd.: negative pressure sealing instrument, sealing tester
