Overview
MFY-01 sealing tester is a CHENCHI brand product, suitable for food, medical apparatus, daily chemical, automotive, electronic components, stationery and other industries Encasement bags, bottles, tubes, cans, boxes and other sealing test, and can be dropped, pressure test after the sealing performance test of the specimen.
Features
1. Adopt manual adjustment of pressure and control of holding pressure, the operation is more convenient and the performance is more stable.
2. All pneumatic components are made of familiar manufacturer products, with stable and reliable performance, and eliminate the unstable pressure holding phenomenon caused by pneumatic components.
3. Good Organic Glass (acrylic) sealing barrel, the wall thickness is increased to 15mm, which effectively enhances the compressive strength of the sealing barrel and prolongs the service life.
4. Electronic holding device, reduce mechanical abrasion, make the holding time longer.
5. PVC operation panel, pressure digital display, resolution accurate to 0.1kPa, convenient for users to accurately view the pressure value.
6. Built-in time display, Timer synchronized timing of pressure holding start, which is convenient for users to record and observe the pressure holding time, and Timer will automatically clear when the pressure holding ends.
Principle
By evacuating the vacuum chamber, the sample immersed in water generates internal and external pressure difference, and observes the internal and external escape of the test sample to determine the sealing performance of the sample. At the same time, by vacuuming the vacuum chamber, the sample generates internal and external pressure difference, and observes the shape recovery of the sample after the test sample expands and releases the vacuum to determine the sealing performance of the sample.
Applications
Food Industry: Soft Bag Encasement, Semi-hard Encasement, Hard Encasement; Medical Apparatus Industry: Closed Container, Blister Encasement, Small Headspace Encasement; Miscellaneous: Tyvek, All kinds of Aluminum Foil Bags, Wet Tissue, Cosmetics Encasement, etc
Standards
GB/T 15171、ASTM D3078
Steps
1. Place the sample in a sealing bucket and immerse it in water.
2. Manually adjust the pressure to the required value.
3. Start the vacuuming process to generate a pressure difference between the inside and outside of the sample.
4. Observe the escape or expansion of the gas in the sample.
5. Record the holding time, and the Timer will automatically time.
6. After releasing the vacuum, observe the recovery of the sample shape.
7. Determine the sealing performance of the sample according to the observation results.
Notice
• Ensure that the air source pressure is 0.7Mpa, and the air source needs to be provided by the user.
• Check whether all pneumatic components are normal before use to avoid unstable pressure holding.
• Pay attention to the wall thickness and material of the sealing barrel to prolong the service life.
• Accurately check the pressure digital display during operation, with a resolution of 0.1kPa.
• Timer automatically clears after the pressure holding is over, no manual operation is required.
• Test with reference to relevant standards GB/T 15171 and ASTM D3078.
