Precautions for use of sealing tester

Sealing tester, also known as sealing tester, sealing tester, leakage tester, vacuum leak detector, air tightness tester, etc., is a professional instrument used to test the sealing performance of packaging The application industry covers food, pharmaceutical, daily chemical, stationery, packaging, electronics, etc through the sealing performance test of packaging, it can provide data support and section for the overall packaging quality performance evaluation It is widely used What are the precautions for the use of sealing tester? In this paper, with the help of wst-02 sealing tester produced by Shandong Weishen Electronic Technology Co., Ltd., the editor makes a detailed introduction 1 Inject clean water into the vacuum chamber, which is higher than the bottom laminate surface on the cylinder head, and immerse the sample in the water At this time, the distance between the top surface of the sample and the water surface shall not be less than 10 mm To ensure the sealing effect, a small amount of water can be sprinkled on the sealing ring 2 Cover the sealing cover of the vacuum chamber and set the test parameters required for the test 3 It is only necessary to ensure that the disclosure of each part of the sample can be observed during the experiment, and two or more samples can be tested at a time 4 The adjusted vacuum value shall be confirmed according to the characteristics of the sample (such as the packaging materials used, sealing conditions, etc.) or the rules of relevant product standards 5 During the vacuumizing process and during the vacuum holding period after reaching the preset vacuum degree, the leakage of the sample depends on whether there is continuous bubble A single isolated bubble is generally not considered to be revealed by the sample 6 Turn the switch on the sealing tester to the open position, eliminate the vacuum, time zero, open the sealing cover, take out the test sample, wipe the water on its surface, and observe the damage result of the packaging bag surface The above is the precautions for the use of the sealing tester Good operation habits help to provide test efficiency I hope the above can help you For more details, please call Shandong Weishen Electronic Technology Co., Ltd to discuss and learn together.
