Diaphragm Peeling Force Testing Machine

The diaphragm peeling tester secures the diaphragm and substrate using fixtures, then peels them apart at a constant speed while measuring the force required for separation. It is used to evaluate the adhesive bonding strength and to inspect the quality of lamination in industries such as battery diaphragms and adhesive tapes.
Selection
When selecting, consider matching the maximum load with sensor accuracy to meet testing requirements. The fixture must accommodate the sample's dimensions and material. The speed control range should cover standard methods, and the data acquisition system must meet the needs for generating basic test reports.

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.
