Serrate corrugated padding and use thereof

The invention relates to serrate corrugated padding and use thereof, Zigzag-pak which is characterized in that: the metal platy material is rolled into to a serrate corrugated shape by a milling machine; one side of the saw-teeth is vertical to the extension direction of a padding sheet; the axis of the corrugation and the vertical direction form an angle; a corrugated plate is cut into rectangular padding sheets with different lengths and the same width; each two adjacent padding sheets are arranged in a staggered way; a plurality of padding sheets are bound to form a circular disk. The peak height (h) of the serrate corrugation is 1.5-8 mm; the serrate angle (alpha) is 15-75 DEG; and the corrugated inclination angle (beta) is 15-60 DEG. Compared with the prior art, the serrate corrugated padding is high in separation effect, low in cost and the like.
