不锈钢纤维长度对不锈钢纤维毡均匀度的影响

INFLUENCE OF THE LENGTH OF THE STAINLESS STEEL FIBER ON THE HOMOGENEITY OF STAINLESS STEEL FIBER FELT

摘要: 不锈钢纤维毡是否均匀主要取决于毡中纤维束及断丝的百分率。采用丝径分别为Φ8μm、Φ12μm、Φ20μm的不锈钢纤维为原料,经剪切、开松、铺毡,然后取样检测毡样中的纤维束及断丝百分率。发现铺毡纤维束百分率随长度的缩短而减少,但断丝的百分率则增加,只有当纤维的长度适当时铺出的毡均匀,不同直径的纤维对应不同的最佳纤维长度。

Abstract: Stainless steel fibers with the diameter of Φ8μm、Φ12μm、Φ20μm were cut, unloosed and rolled out to form pieces of felt. The percentages of the bunchy fiber and the broken fiber in the felt were inspected. The results show that the percentage of bunchy fiber reduces, but the percentage of broken fiber increases as the length of the fiber being formed the felt increases. So the homogeneous fiber felt should be gained with the fiber of suitable length.
