style="text-indent:25px">目前企業(yè)有一種共識(shí)，希望冶金膠輥膠圈的周期越長越好。愿望是美好的，事實(shí)上在國內(nèi)目前技術(shù)的條件下是很難實(shí)現(xiàn)的，上海冶金膠輥廠家哪家好。只有通過合理的保養(yǎng)、合理的工藝設(shè)備配套才能延長壽命。但實(shí)際使用中卻出現(xiàn)了一個(gè)奇怪的現(xiàn)象，一方面強(qiáng)調(diào)使用周期長，另一方面卻連基本的保養(yǎng)都不做，結(jié)果出現(xiàn)了很多問題，如冶金膠輥膠圈中凹、繞花、開裂，產(chǎn)生了大量的紗疵。其實(shí)通過合理保養(yǎng)延長冶金膠輥膠圈壽命是完全可行的，使用65度不處理冶金膠輥紡純棉緊密紡回磨周期達(dá)六到八個(gè)月，而質(zhì)量基本無影響。他們做法無非是保養(yǎng)到位，如冶金膠輥7天左右下車回彈，加壓適當(dāng)，回磨之前適當(dāng)自然回復(fù)等。一家大型國企使用73度不處理冶金膠輥紡新型纖維素纖維緊密紗時(shí)，上海冶金膠輥廠家哪家好，回磨周期同樣能做到四個(gè)月以上，上海冶金膠輥廠家哪家好。進(jìn)口膠輥由于磨礪周期較長，長時(shí)間在車上運(yùn)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。上海冶金膠輥廠家哪家好</p><div

了解了冶金膠輥的檢測標(biāo)準(zhǔn)，我們自然要介紹一下冶金膠輥的檢測項(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。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標(biāo)準(zhǔn)中都有提到，所以我們也可以作為冶金膠輥檢測的參考指標(biāo)。 </p> <p> 冶金膠輥檢測項(xiàng)目主要有： </p> <p> 1、冶金膠輥硬度檢測項(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 /> 上海冶金膠輥廠家哪家好膠輥膠圈是直接影響紡紗質(zhì)量重要的紡紗器材之一。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="上海冶金膠輥廠家哪家好,冶金膠輥" src="https://tyunfile.71360.com/WaterMark/UploadFile/wxqzxj/637318170165292968/6210466.png"></div><p style="text-indent:25px">前冶金膠輥硬度選型主要是根據(jù)紡紗號(hào)數(shù)和纖維的性能、壓力工藝等綜合決定。一般純棉使用邵氏硬度65度左右冶金膠輥，粘膠選用68-70度左右冶金膠輥，化纖選用70度以上冶金膠輥。但在實(shí)際中卻發(fā)現(xiàn)兩種錯(cuò)誤傾向。一是片面追求質(zhì)量，不顧自己工廠的實(shí)際條件，如環(huán)境、原料等，盲目選用硬度低的冶金膠輥，甚至滌綸等品種也選用65度冶金膠輥，配套工藝處理?xiàng)l件又跟不上；二是片面追求周期，選用硬度偏高的冶金膠輥。這樣選擇冶金膠輥導(dǎo)致了兩種極限反映，不是冶金膠輥嚴(yán)重受損、周期縮短、質(zhì)量惡化，就是質(zhì)量水平達(dá)不到要求。這種錯(cuò)誤選擇主要是源于對質(zhì)量認(rèn)識(shí)的誤區(qū)及對冶金膠輥硬度和耐磨性能認(rèn)識(shí)上的誤區(qū)。對質(zhì)量的認(rèn)識(shí)。目前大家公認(rèn)好的質(zhì)量，應(yīng)該是指長期和穩(wěn)定的質(zhì)量，并確保紗疵穩(wěn)定，而并不是片面追求條干質(zhì)量的改進(jìn)，因?yàn)闂l干越好，對管理要求及器材的要求越嚴(yán)，出現(xiàn)大錠差的概率也越大。冶金膠輥硬度相對較軟，固然能夠提高條干水平，但由于軟冶金膠輥?zhàn)冃屋^大，相對更容易帶來?xiàng)l干的變異，況且冶金膠輥損傷的幾率增加，我們并不能保證損壞冶金膠輥能夠時(shí)間從車上取下，從而導(dǎo)致大量的紗疵及壞紗。</p><p 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。膠輥硬度越軟質(zhì)量越好，這是廣大技術(shù)人員的共識(shí)。</p><div

style="text-indent:25px">冶金膠輥直徑的選擇還存在另一種誤區(qū)。這主要發(fā)生在四羅拉緊密紡裝置中。原則上牽伸冶金膠輥和導(dǎo)向冶金膠輥直徑應(yīng)該一致，以利于互換，減少工作量，管理方便。但在實(shí)際使用中卻發(fā)現(xiàn)完全不是如此。不少企業(yè)兩種冶金膠輥直徑甚至相差太大，以致產(chǎn)生了很多問題。導(dǎo)向冶金膠輥直徑如果超過30mm,，容易碰網(wǎng)格圈影響質(zhì)量和生產(chǎn)的順利進(jìn)行，甚至使加壓不能正常進(jìn)行，使搖架疲勞加劇，消耗嚴(yán)重增加。導(dǎo)向冶金膠輥如果過小，容易使網(wǎng)格圈打頓，出現(xiàn)嚴(yán)重的粗細(xì)節(jié)紗疵。因此兩種冶金膠輥直徑差比較好不要大于0.4mm，否則容易出現(xiàn)許多不必要的問題。膠輥上車使用時(shí)，應(yīng)避免同品種、多批次、多廠家的產(chǎn)品同時(shí)在一個(gè)區(qū)域使用。上海冶金膠輥廠家哪家好</p><p style="text-indent:25px">膠輥在滿足紡紗質(zhì)量要求時(shí)，必須保持足夠抗繞性、耐油性和優(yōu)良的彈性。上海冶金膠輥廠家哪家好</p><p> 一般產(chǎn)生吐硬頭和繞冶金膠輥的原因有：溫濕度的變化、纖維含油劑多少、纖維的棉蠟含糖變化情況、纖維的長度、線密度超出紡紗設(shè)計(jì)要求、特殊纖維的特殊性能等。只有找到吐硬頭繞冶金膠輥的真正原因，做到有的放矢，才能有效的解決問題。在膠圈使用方面的經(jīng)驗(yàn)：膠圈不良直接影響紡紗的順利進(jìn)行，如膠圈表面粘著纖維就會(huì)形成紗疵，影響成紗條干均勻度及單紗強(qiáng)力，造成粗、細(xì)節(jié)及竹節(jié)紗等，絡(luò)筒百管斷頭率明顯增加。另外，由于膠圈不能很好的控制纖維，會(huì)造成成紗節(jié)粗、節(jié)細(xì)，也會(huì)增加細(xì)紗斷頭，增加擋車工的勞動(dòng)強(qiáng)度。 </p> <p> 膠圈不良一般有以下幾種：膠圈內(nèi)徑超差、中凹、表面?zhèn)?、?nèi)層斷裂(或簾子線斷裂)、外層表面老化龜裂、內(nèi)外層不滑爽、有疵點(diǎn)夾入等，有時(shí)還會(huì)產(chǎn)生機(jī)械波。 </p> <p> <br /> 上海冶金膠輥廠家哪家好</p><p
