LT-XZ 21 Adhesive tape fatigue testing machine | fatigue testing machine | adhesive tape repeated opening and closing testing machine

Short Description:

This machine in the adhesive buckle belt (Velcro belt) repeatedly for stripping and fitting action, after a certain number of times, and then to buy the pull test

Machine, determine the adhesive force (AS) and bond strength (PA). This machine is suitable for all kinds of shoes. For the opening and closing of the hook surface of the adhesive buckle together under the specified conditions, peel the required average force value from either end of the adhesive strip along the length direction, then reverse the hook surface or ring surface by 180°, and repeat this step to measure the stripping strength of the adhesive buckle.

Technical parameters

1. Two circular wheels with a width of at least 70mm, one diameter (160.0 ± 0.5) mm and the other diameter (162.5 ± 0.5) mm, each with a cut groove of (55 ± 2) mm in its width direction to secure the adhesive buckle. Two rotors are installed against each other, and the axes are parallel to each other;

2. The rotation rate of the small diameter runner is (60 ± 5) r/min, and every (30 ± 5) s reverses, the large diameter runner is driven by the physical contact between the sample and the small diameter runner, so as to rotate freely;

3. Two wheels apply force (1.0 ± 0.1) N on the width of the sample;
