Test procedure for drug vacuum bottle sealability tester Sealing Tester: As material life becomes more and more abundant, people's requirements for product packaging are not only to protect goods from damage and aesthetic requirements. At the same time, it also requires a variety of functions such as preservation, anti-corrosion, anti-bacterial, anti-counterfeiting, and extended shelf life. Now we focus on the main performance indicators of packaging preservation, anti-corrosion, anti-bacterial, anti-counterfeiting, and extended shelf life - the "sealing" of packaging. Jinan Jingji designed this sealing tester to judge the sealing performance of the sample by vacuuming the vacuum chamber and making the internal and external pressure difference of the sample immersed in water to observe the gas escape condition of the sample; The vacuum chamber is evacuated to make the sample have an internal and external pressure difference, and the shape of the sample is recovered after the sample is expanded and the vacuum is released, thereby determining the sealing performance of the sample. The sealing tester is suitable for the sealing test of packaging bags, bottles, tubes, cans, boxes, etc. in food, pharmaceutical, medical equipment, daily chemicals, automobiles, electronic components, stationery and other industries. The sealability tester can also perform the sealing performance test of the test piece after the drop and pressure test. Sealing tester test process 1 Inject clean water into the vacuum chamber, the height exceeds the surface of the bottom plate on the cylinder head, and put the sample. The distance between the top surface of the sample and the water surface should not be lower than 25 mm to ensure the sealing effect, and sprinkle a little 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 knob of the tester (see above for adjustment method), observe the vacuum pressure gauge, and adjust the pressure to the stable value required for the test. . 3 to reach the required pressure, turn the tester's switch to the off position, maintain the vacuum, the timer starts to count, observe the sample, and reach the dwell time. Note: The adjusted vacuum value is determined according to the characteristics of the sample (such as the packaging materials used, the sealing conditions, etc.) or the relevant product standards. 4 Leakage of the sample during vacuum evacuation and after the preset vacuum is reached, depending on whether or not continuous bubbles are generated. A single isolated bubble is generally not considered a sample leak. 5 When the pressure holding time is reached, the switch on the instrument is turned to the off position, the vacuum is removed, the sealing cover is opened, the test sample is taken out, the water on the surface is wiped clean, and the surface damage result of the packaging bag is observed.
