Product Introduction
Folding is one of the fundamental mechanical properties of paper, which is defined as the Under the specified conditions, the number of double folds the sample can withstand before breaking indicates that the paper can withstand repeated folding. This power is necessary for paper bag paper and currency paper, and is also suitable for printing paper, drawing paper, packaging Folding test paper, etc. This instrument is an instrument used to measure the folding endurance of paper.
Test principle:
MIT type folding tester specializes in testing the folding strength of paper and cardboard, is the most typical type of paper fatigue test. The test method is to fix the two ends of the test piece on the upper and lower fixtures of the instrument, and the requirementapply too much load to make the test piece bear a certain stress. fixture is in the vertical state of the test piece Bend the sample down, left and right, with a bending angle of 135 degrees, back and forth until the test piece is broken, and count automatically.
