adopting the riblet structure of sharkskin as a templet, two ways of micro-replication, replicated moulding and electroforming, were used to replicate the microstructure on the surface of a polymer.
以鲨鱼皮表面的盾甲鳞结构为模板,采用复型翻模法和电铸法,在高分子表面进行表面微结构的复制。
sharkskin also has close relation to the interfacial condition between melt and die wall.
鲨鱼皮畸变的产生与熔体和界面情况密切相关。
it shows that with the shear rate rising, the average wavelength and average depth of sharkskin both increased, so the sharkskin became more obvious;
通过对鲨鱼皮肋状物的波长和深度的定量描述,发现随剪切速率增加,鲨鱼皮的平均波长和平均深度均增加;
meanwhile, binary processing aid also showed effect on increasing the critical shear rate for the onset of sharkskin melt fracture.
