<p> 使用丁腈再生膠生產(chǎn)的冶金膠輥可以長時間工作在100℃的環(huán)境中，三元乙丙再生膠冶金膠輥的使用溫度范圍比之還要廣一些。丁腈冶金膠輥與三元乙丙再生膠冶金膠輥性能不同，作用不同，橡膠制品廠家可以根據(jù)自身產(chǎn)品的用途選擇合適的再生膠種類，替代原膠明顯降低原料成本。 </p> <p> <br />

style="text-indent:25px">冶金膠輥是以金屬或其他材料為芯，外覆橡膠經(jīng)硫化而制成的輥狀制品。一般由外層膠、硬質(zhì)膠層、金屬芯、輥頸和通氣孔組成，其加工包括輥芯噴砂、黏合處理、貼膠成型、包布、鐵絲纏繞、硫化罐硫化及表面加工等工序。產(chǎn)品應(yīng)用在電子、紡織、皮革、家具、玻璃、紙張印刷等領(lǐng)域。根據(jù)產(chǎn)品的使用性能要求，可分為提供耐熱、耐磨、耐油、耐射線、耐酸堿、耐化學(xué)藥品和特殊介質(zhì)的質(zhì)量冶金膠輥。還可根據(jù)客戶需求量身定制個性化冶金膠輥。從紡紗品種、纖維特性、紡紗工藝要求等方面，分析了合理選擇冶金膠輥膠圈硬度、彈性的要素及冶金膠輥膠圈合理搭配使用的方法。針對紡紗過程中冶金膠輥膠圈出現(xiàn)纖維纏繞、表面中凹、須條牽伸不開等問題，提出了解決措施。指出：冶金膠輥膠圈作為重要的牽伸器材，要充分發(fā)揮其在紡紗中的作用，不斷地通過技術(shù)創(chuàng)新生產(chǎn)出更加適應(yīng)不同紡紗品種的冶金膠輥膠圈。認(rèn)為：通過工藝的創(chuàng)新、新材料的應(yīng)用、專件器材的智能制造，可提升冶金膠輥膠圈的質(zhì)量。</p><p style="text-indent:25px">冶金膠輥種類的選擇一般以品種和號數(shù)來決定。純棉品種盡量選擇免處理，但對使用外棉、棉蠟多等原料一般使用微處理冶金膠輥。滌棉品種視混紡號數(shù)盡量使用免處理和微處理冶金膠輥。純滌品種一般選用處理冶金膠輥，但溫濕度控制好的企業(yè)，可選用微處理。用戶的質(zhì)量要求高，一般選用免處理。質(zhì)量要求低，一般選用處理冶金膠輥。這是冶金膠輥種類選擇的基本原則。但不少企業(yè)在選擇時不管什么品種一律選用免處理冶金膠輥，以為這樣就能起到一勞永逸的目的。殊不知，這樣不僅成本增加了，而且在部分品種上也會出現(xiàn)不必要的問題。如在純滌綸品種上，嚴(yán)格意義來說，目前的免處理冶金膠輥是不適用的。主要是其油劑的特殊性和耐磨性要求。如果非要使用，也需要使用特殊的處理方法。這樣處理很多企業(yè)沒有條件，而且其效果甚至不如普通冶金膠輥，往往得不償失。針對品種及質(zhì)量要求選用合適的冶金膠輥種類。純棉一般采用免處理。滌綸及滌綸含量高原則上選用處理或微處理冶金膠輥。對平面牽伸來說，膠輥硬度要求比前膠輥高5-10度，直徑要求比前膠輥小0.5mm~1.5mm,。</p><div

冶金膠輥直徑大固然有利于牽伸力界的延伸，在一定的壓力和冶金膠輥硬度的情況下，對于成紗質(zhì)量有利。因此，如果在工藝和設(shè)備的情況下，冶金膠輥直徑適當(dāng)加大還是可行的。但一旦超出范圍過大，工藝設(shè)備不隨之變化，就容易引起橡膠變形過大，易引起機(jī)械波，而且摩擦力界分布重新發(fā)生了變化，在現(xiàn)有搖架結(jié)構(gòu)下，易造成中區(qū)失壓，牽伸效率極不穩(wěn)定，條干、紗疵惡化明顯。而且，橡膠有一個自然老化期，一般為二年左右，即使在不用的情況下，橡膠的彈性和硬度也會發(fā)生大小不等的變化，導(dǎo)致成紗CVb嚴(yán)重增加。 </p> <p> <br /> 根據(jù)牽伸要求、選型原則選用后區(qū)膠輥，切不可為了節(jié)約盲目選用不合適后膠輥，出現(xiàn)質(zhì)量偏差。上海冶金膠輥價格表</p><p style="text-indent:25px">傳統(tǒng)認(rèn)為膠輥表面粗糙度越小越好，膠輥表面細(xì)膩，不易繞花，從而達(dá)到膠輥“光，滑，燥，爽”的四點要求。上海冶金膠輥哪家比較便宜</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(dá) 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(hù)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(hù)有很大的好處。磨礪后的冶金膠輥表面要滑爽、細(xì)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(jī)，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。上海冶金膠輥哪家比較便宜</p></p><br /><p>文章來源地址:
