Brief introduction of the test method of the sealing tester for filled milk powder

Brief introduction of the test method of the sealing tester for filling milk powder The inner and outer pressure difference of the sample in is generated, and the gas escaping in the sample is observed to determine the sealing performance of the sample; the inner and outer pressure difference of the sample is generated by vacuuming the vacuum chamber, and the shape recovery of the sample after expansion and vacuum release is observed to determine the sealing performance of the sample Note: product model of sealing tester mfy-1 (economic type) product purpose: mfy-1 sealing tester is applicable to the sealing test of packaging bags, bottles, tubes, cans, boxes, etc in food, pharmaceutical, medical devices, daily chemical, automobile, electronic components, stationery and other industries It can also test the sealing performance of the test piece after the drop and pressure test Features of the product: 1 It adopts manual control to maintain pressure, which makes operation more convenient and performance more stable 2 All pneumatic components are made by famous manufacturers with stable and reliable performance The phenomenon of pressure maintaining instability caused by pneumatic components is eliminated 3 Plexiglass (acrylic) sealed barrel, with the wall thickness increased to 15mm, effectively enhances the compressive strength of the sealed barrel and prolongs the service life 4 The electronic pressure maintaining device can reduce the mechanical wear and make the pressure maintaining time longer 5 PVC operation panel, pressure pointer display, instant, convenient for users to quickly view the pressure value Test principle: by vacuuming the vacuum chamber, the internal and external pressure difference of the sample immersed in water is generated, and the gas escaping in the sample is observed, so as to determine the sealing performance of the sample; by vacuuming the vacuum chamber, the internal and external pressure difference of the sample is generated, and the sample shape recovery after expansion and vacuum release is observed, so as to determine the sealing performance of the sample Technical parameters 1 Vacuum degree: - 90kpa ～ 0 2 Precision: Level 1 3 Effective dimension of vacuum chamber: Φ 270mm × 200mm (H) (standard configuration) Note: other dimensions can be customized 4 Air source pressure: 0.7MPa (provided by the user) 5 Air source interface: Φ 8 polyurethane pipe 6 Boundary dimension: 460mm (L) × 360mm (b) × 530mm (H) 7 Power source: AC 220V50Hz 8 Net weight: 12kg standard configuration: host + experimental seal barrel + air source line according to the standard: GB / T 15171, ASTM d3078 more!
