直徑的選擇主要根據(jù)成紗質(zhì)量的要求及搖架工藝的設(shè)定來決定。在現(xiàn)有工藝及設(shè)備條件下，一般前冶金膠輥直徑在28mm~30.5mm,，在實際生產(chǎn)中，大部分企業(yè)冶金膠輥直徑的選擇都在上述范圍內(nèi)，小直徑大家都不會選擇，因為過小的直徑，橡膠容易失去彈性，導致硬度加大，對纖維握持能力差，條干惡化。但對直徑上限選擇就不一樣，上海冶金膠輥批發(fā)價格，在目前紡織形勢十分嚴峻的形勢下，上海冶金膠輥批發(fā)價格，為了節(jié)約成本，冶金膠輥直徑已突破上限范圍，個別企業(yè)甚至達到36mm左右，認為這樣冶金膠輥的彈性又好，回磨的次數(shù)又多，能夠達到節(jié)約成本和提高質(zhì)量的雙層目的，上海冶金膠輥批發(fā)價格。其實這是一個很大的誤區(qū)，存在很多的弊端。

style="text-indent:25px">冶金膠輥選用誤區(qū)主要體現(xiàn)在以下幾個方面。一是為了節(jié)約成本，很多企業(yè)將前冶金膠輥淘汰下來后調(diào)至后檔，這樣表面上看是節(jié)約了，實際上對質(zhì)量的危害很大。尤其對高支紗及質(zhì)量要求較高的紗線。主要是因為橡膠老化程度不一樣，導致后冶金膠輥的硬度不一致，結(jié)果成紗重不勻增大和錠差增大。同時摩擦力界的變化也容易出隱性硬頭和隱性機械波問題。二是新建廠直接配置較大直徑后冶金膠輥或者較軟冶金膠輥甚至比前擋還低，這樣配置極易導致后區(qū)控制力和引導力不吻合而引起牽伸不穩(wěn)定。三是很多企業(yè)為了提高質(zhì)量選用鋁襯不處理冶金膠輥。其實大可不必，由于后冶金膠輥運轉(zhuǎn)速遞低，且壓力比前區(qū)小，一般選用雙層，檔次不高甚至可選用單層冶金膠輥，這樣也有利于節(jié)約成本。四是V型牽伸后區(qū)冶金膠輥直徑偏小，甚至低于前皮輥較多，導致后冶金膠輥壓空影響產(chǎn)品質(zhì)量和生產(chǎn)的順利進行。進口膠輥由于磨礪周期較長，長時間在車上運轉(zhuǎn)的膠輥易老化，成紗質(zhì)量隨著膠輥使用周期的延長而有所降低。上海冶金膠輥批發(fā)價格</p><p style="text-indent:25px">在膠輥膠圈的使用過程中，要著重預防牽伸不開吐硬頭和繞膠輥現(xiàn)象。上海冶金膠輥批發(fā)價格</p><p style="text-indent:25px">冶金膠輥選用先考慮其纏繞性、耐磨性等。并條、精梳冶金膠輥在高速運轉(zhuǎn)下發(fā)熱量大，冶金膠輥表面溫度高（達 50 ℃~60 ℃），容易纏繞和磨損；冶金膠輥的耐磨性不好，容易損壞冶金膠輥。并條鐵芯采用免維護鐵芯，鐵芯軸頭與套筒摩擦因數(shù)小、發(fā)熱量小、振動也小，對紡紗質(zhì)量和冶金膠輥的維護有很大的好處。磨礪后的冶金膠輥表面要滑爽、細膩，特別是主牽伸冶金膠輥表面粗糙度要小（≤0. 5 μm），以減少纏繞。紡純棉精梳紗品種，主牽伸冶金膠輥一般選用 HA65S 型冶金膠輥（邵爾 A65 度）、Accotex?121 型冶金膠輥（邵爾 A72 度）、新制作或回磨的冶金膠輥上機，可先在末道磨合幾個班次，再調(diào)到頭道并條使用，有利于減少纏繞。上海冶金膠輥批發(fā)價格</p></p><br /><p>文章來源地址: http://www.cdcfah.com/cp/2831667.html</p></div></div></div></div></div><div
