    Cathodic Disbondment Test Machine

    Overview Knowledge Standards Terms
    The cathodic disbondment test machine simulates corrosive environments by applying a cathodic potential to measure the bonding strength between the coating and the substrate. It is used to evaluate the durability of anti-corrosion coatings on metal structures such as pipelines and ships, and to detect the coating's resistance to disbondment under electrochemical conditions.
    Selection
    Select the fixture specifications based on the thickness of the material being tested; match the potential range to the actual corrosion environment; confirm that the load sensor accuracy meets the requirements for coating strength testing; consider the compatibility of the sample size with the tank volume; verify whether the temperature control function covers the application scenario.

    Application of Small Push-pull Force Gauge in Rapid Inspection of Adhesive Peel Strength for Mobile Phone Screens
    This article introduces how to quickly test the peel strength of adhesive on phone screens using a small push-pull gauge.
    Peel strength tester measures the peel force of hot melt adhesive resin.
    The peel strength tester is used to measure the adhesive properties of hot melt adhesive resins, simulating the actual peeling process by recording changes in force values through constant-speed stretching.
    The 180-degree peel strength test for tape shows a 50% deviation in data due to misalignment of the sample.
    In the 180-degree peel strength test of adhesive tape, if the sample is misaligned, the test data may drop by about half. This is because misalignment causes uneven force distribution during peeling, reducing the effective peel strength.
