NN、EP輸送帶在外觀上(shang)的區別是：
強度(du)(du)等級相(xiang)同的NN輸(shu)送(song)(song)(song)(song)帶(dai)、EP輸(shu)送(song)(song)(song)(song)帶(dai)，NN輸(shu)送(song)(song)(song)(song)帶(dai)相(xiang)對薄(bo)一(yi)(yi)點(dian)，從斷面看紗線(xian)紋(wen)路相(xiang)對緊錯一(yi)(yi)點(dian)，EP輸(shu)送(song)(song)(song)(song)帶(dai)的紗線(xian)從側面看彎曲程度(du)(du)比較大，兩個(ge)波峰之間的距離(li)相(xiang)對比較大。此外，NN輸(shu)送(song)(song)(song)(song)帶(dai)帶(dai)體相(xiang)對柔軟一(yi)(yi)點(dian)，EP相(xiang)對硬一(yi)(yi)點(dian)。
