國內(nèi)棉紡行業(yè)的發(fā)展快速，緊密紡、賽絡(luò)紡、嵌入紡等紡紗工藝日趨成熟，高效率、高效益紡紗帶來紡織機(jī)械高速化，紡紗品種多樣化 (粘膠、天絲、莫代爾、絹絲等)，形成的技術(shù)重要是紡紗高速化、前紡重定量、細(xì)紗大牽伸、紗線***的紡紗工藝,對(duì)冶金膠輥帶來四方面新問題。 </p> <p> （1）工作溫度上升。橡膠體工作中產(chǎn)生的熱量與工作速度、受壓以及摩擦量有關(guān)。在高壓高速條件下，單位時(shí)間內(nèi)冶金膠輥形變數(shù)量增多，橡膠分子鍵容易因不斷快速蠕變而僵硬。 </p> <p> （2）摩擦量增加。高速條件下，單位時(shí)間內(nèi)纖維通過冶金膠輥的次數(shù)增加，冶金膠輥的磨耗量增加。 </p> <p> （3）高速、高壓條件下，膠體的形變力大于形變次數(shù)，冶金膠輥與鐵芯的結(jié)合面受到剪切力和剝離力增大。 </p> <p> （4）新型纖維紡紗，對(duì)冶金膠輥耐油性、抗靜電性提出了更高的要求。 </p> <p> <br /> 上海冶金膠輥有什么用對(duì)軟膠輥，宜采取大隔距適當(dāng)加壓工藝。</p><div style="width:100%;text-align:

冶金膠輥的質(zhì)量主要取決于膠料的配方設(shè)計(jì)，丁腈橡膠(NBR)仍是目前紡紗冶金膠輥的推薦膠種。冶金膠輥的質(zhì)量主要取決于膠料的配方設(shè)計(jì)，丁腈橡膠(NBR)仍是目前紡紗冶金膠輥的推薦膠種。配方的確定需要進(jìn)行大量的試驗(yàn)，其中對(duì)性能影響較大的幾種材料可以采用正交法設(shè)計(jì)多組方案，再通過機(jī)械性能比較進(jìn)行優(yōu)化，以篩選出理想的配方設(shè)計(jì)。 </p> <p> 冶金膠輥的成型方式一般有三種：直接包膠模壓硫化；膠管擠出一硫化罐硫化成型；鋁襯管膠管套裝成型。第一種成型工藝缺點(diǎn)是效率低、成本高，但比較大優(yōu)點(diǎn)是膠層密實(shí)，膠層與輥芯粘結(jié)牢靠而不會(huì)出現(xiàn)脫輥現(xiàn)象，使用壽命長。后兩種制造工藝使用的成型設(shè)備主要為擠出機(jī)和硫化罐，是現(xiàn)在冶金膠輥制造企業(yè)普遍采用的成型工藝。 </p> <p> <br /> </p><p> <br /> </p> <p> 了解了冶金膠輥的檢測(cè)標(biāo)準(zhǔn)，我們自然要介紹一下冶金膠輥的檢測(cè)項(xiàng)目。冶金膠輥的品質(zhì)好壞是要綜合考量的，主要可以從硬度、物理性能、化學(xué)性能、表面特性、其他等方面入手檢測(cè)。當(dāng)然硬度屬于冶金膠輥的物理性能。除此之外，冶金膠輥輥芯在大部分檢測(cè)標(biāo)準(zhǔn)中都有提到，所以我們也可以作為冶金膠輥檢測(cè)的參考指標(biāo)。 </p> <p> 冶金膠輥檢測(cè)項(xiàng)目主要有： </p> <p> 1、冶金膠輥硬度檢測(cè)項(xiàng)目：橡膠國際硬度、趙氏硬度、邵爾A硬度 </p> <p> 2、冶金膠輥用膠料物理性能檢測(cè)項(xiàng)目：硬度、硬度公差、拉伸強(qiáng)度、拉伸伸長率、屈撓龜裂、撕裂強(qiáng)度、壓縮長久表現(xiàn)、回彈性、耐油質(zhì)量變化率、阿克隆磨耗、吸振性、摩擦性能 </p> <p> 3、冶金膠輥用膠料化學(xué)性能檢測(cè)項(xiàng)目：耐液體性能、耐酸試驗(yàn)、耐堿試驗(yàn)、熱空氣老化、耐腐蝕性、導(dǎo)電性、傳熱性、親水性、耐溶劑性 </p> <p> <br /> 膠輥?zhàn)鳛橹匾臓可煸?，其性能、管理水平都與成紗質(zhì)量密切相關(guān)。</p><div style="width:100%;text-align:

style="text-indent:25px">冶金膠輥的硬度、彈性和表面摩擦因數(shù)的關(guān)系。同一種冶金膠輥一般以表面不處理的摩擦因數(shù)比較大，經(jīng)過處理的冶金膠輥一般隨著硬度降低而增加其表面摩擦因數(shù)。硬度主要影響冶金膠輥的變形，硬度高變形小，反之則大。冶金膠輥的彈性主要影響摩擦力界的分布，鉗口的接觸面對(duì)須條邊緣纖維控制，高彈性冶金膠輥受壓變形大，使鉗口接觸面積增加，提高鉗口的縱向握持力，減少受羅拉溝槽凹凸部位的波動(dòng)。低硬度冶金膠輥一般控制在邵爾 A60 度以上，在搖架壓力作用下轉(zhuǎn)動(dòng)后，能夠迅速恢復(fù) 其彈性形變，保持冶金膠輥有良好的彈性。因?yàn)樵谙嗤膿u架壓力下，冶金膠輥對(duì)纖維須條握持的越好，就越能改善和提高紡紗的質(zhì)量。低硬度高彈性冶金膠輥對(duì)設(shè)備狀態(tài)、工藝要求等方面要求較高，紡紗企業(yè)要充分認(rèn)識(shí)到低硬度高彈性冶金膠輥的特性，選擇適合本企業(yè)紡紗用的冶金膠輥。對(duì)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,。上海冶金膠輥批發(fā)報(bào)價(jià)</p><p

style="text-indent:25px">其次對(duì)冶金膠輥耐磨性能及硬度關(guān)系的認(rèn)識(shí)同樣存在誤區(qū)。。通常認(rèn)為冶金膠輥越硬，耐磨性能越強(qiáng)。其實(shí)這是一種片面的認(rèn)識(shí)。我們認(rèn)識(shí)只是基于同一橡膠配方體系的前提下。在不同的配方體系下就不一樣了。如我們?cè)诎炯喼惺褂?5度不處理冶金膠輥發(fā)現(xiàn)其比80度處理冶金膠輥還要壽命長。這都是由于認(rèn)識(shí)錯(cuò)誤所造成的。一般的解決方案是前冶金膠輥的硬度選型根據(jù)自己的質(zhì)量需求、所紡品種、紗支等綜合決定。避免兩個(gè)極端，必須兼顧條干和質(zhì)量，一般在質(zhì)量滿足要求的前提下以硬度稍高一點(diǎn)為宜。根據(jù)自身的實(shí)際情況，在許可范圍內(nèi)合理選用冶金膠輥直徑，不宜過大，如需增大，也要考慮工藝配套和回磨周期，避免浪費(fèi)和質(zhì)量惡化。對(duì)緊密紡牽伸冶金膠輥和導(dǎo)向皮輥直徑配置，建議按標(biāo)配30mm配置，考慮到實(shí)際使用的情況，兩種冶金膠輥的直徑也不宜相差太大。上海冶金膠輥廠商哪家好</p></p><br
