Twist angle tester XN-720 is mainly applicable to the determination of individual high-density polyethylene stretch film twist angle of residues, longitudinal tear length value, is widely used in film production enterprises, quality inspection and other institutions.
Twist angle tester
Test principle
When the sample is rotated 720 degrees and placed on the angle check box for 30 mins, and the rest angle of the rebound is recorded, that is twist residue angle. Rotated the thin film sample 720 degrees by twist tester, take the film down and flattened, Measuring and calculating the length of the 1/2 and the sum of the length of the gap, that is, the length of the longitudinal tear.
