    How shouldlayered enterprises with toothpaste composite hoses appear?now on the market toothpaste is full of, but most are used in hose packaging, common lying in all plastic and aluminum composite hosesThe general structure is thermal seal/adhesive/barrier/adhesive/printing layer, from the inside outThe all-plastic barrier layer is EVOH, and the aluminum barrier layer is aluminum foilThe composite strength of the composite layer has a direct impact on the overall performance of the toothpaste hose, and has the effect of 1 plus 1 2 in terms of mechanical performance and barrier performanceIf the compound strength is low, it may cause compound layer separation of toothpaste hoses during transport storage, affecting the shelf life quality of toothpasteTherefore, enterprises need to test the quality of toothpaste composite hose control, corresponding to the need to detect the project is: "toothpaste composite strength"toothpaste composite hose composite strength test can be evaluated by testing the strength of the hose, test instruments can choose to use Labthink Languang production ofXLW (PC) intelligent electronic pull test machine, standard QB/T 2901-2007 toothpaste with aluminum composite hose in the hose strength testrequirements: Cut out sphenosis with a width of 15 mm and a length of 150 mmAlong the vertical of the composite sheet to take the left, center, right three, along the length direction of the specimen will be the composite layer and substrate pre-stripped 50 mm, stripped part should not have obvious damage, clamped in the grip of the pull machine, using 90 degrees angle, at a speed of 100 mm /min for detection, recording stable dataprepare samples in accordance with QB/T 2901-2007 requirementsAdjust the distance between instrument clamps to 50 mm and install clamp specimensSet the detection parameters, set the test speed of 100 mm/min, start the testIn order to ensure the accuracy of the test results, invalid head length and invalid tail length can be set, and the unstable data at the beginning and end of the experiment can be excluded XLW (PC) is equipped with professional software and large LCD screen, in the test process can intuitively observe the force value change curve, convenient and effective judgment of the peeling process, can find and record the fluctuation of force value in the test process, to provide guidance for the determination of composite strength Technical parameters of the XLW (PC) intelligent electronic pull tester: specification: 500N (standard), 50N, 100N, 250N (optional), 750N, 1000N (customizable) accuracy: 0.5 Test speed: 50 100 150 200 250 300 500/min
    Number of specimens: 1 piece specimen width: 30 mm (standard fixture) 50 mm (optional fixture) travel: 1000mm
    form factor: 450mm (L) x 450mm (W) x 1410mm (H) Power: 220VAC 50Hz 50Hz / 120 60Hz net weight: 68kg
