膠圈選用一般掌握“上軟下硬、外軟內硬、上松下緊”的原則，實際應用中為了減少走熟期通常采用新舊搭配的方法。一般標準配置為上圈0.9×28×37，下圈1.0×30×83，特殊機型膠圈的內徑可能會有不同要求，特別工藝要求的膠圈厚度也可能會有細微變化，如少數(shù)工廠紡高支紗采用較小的鉗口隔距，上圈采用0.85mm，下圈采用0.9mm厚度的配置。膠圈選用的誤區(qū)主要是片面強調壽命、耐磨，因此往往選擇膠圈的時候以厚、硬為原則，不根據(jù)品種，上海冶金膠輥產品介紹、季節(jié)變化等因素做變動，常常出現(xiàn)剛開始上車時牽伸不開現(xiàn)象。事實上這是很片面的認識，這樣固然延長了使用壽命，卻往往容易使上下膠圈運行不同步，嚴重時出現(xiàn)打頓現(xiàn)象，造成大量的紗疵。這種情況在粗紗更明顯，上海冶金膠輥產品介紹，主要是粗紗加壓重、定量大所致。板簧加壓時也常常出現(xiàn)此現(xiàn)象，主要是板簧上銷缺乏彈性所致。 </p> <p> 根據(jù)牽伸要求、選型原則選用后區(qū)冶金膠輥，切不可為了節(jié)約盲目選用不合適后冶金膠輥，上海冶金膠輥產品介紹，出現(xiàn)質量偏差?；蛘卟豢紤]成本需要盲目選用比較好次冶金膠輥，導致質量過剩及浪費。 </p> <p> <br /> 傳統(tǒng)認為膠輥表面粗糙度越小越好，膠輥表面細膩，不易繞花，從而達到膠輥“光，滑，燥，爽”的四點要求。上海冶金膠輥產品介紹</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="上海冶金膠輥產品介紹,冶金膠輥"

了解了冶金膠輥的檢測標準，我們自然要介紹一下冶金膠輥的檢測項目。冶金膠輥的品質好壞是要綜合考量的，主要可以從硬度、物理性能、化學性能、表面特性、其他等方面入手檢測。當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準中都有提到，所以我們也可以作為冶金膠輥檢測的參考指標。 </p> <p> 冶金膠輥檢測項目主要有： </p> <p> 1、冶金膠輥硬度檢測項目：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目：硬度、硬度公差、拉伸強度、拉伸伸長率、屈撓龜裂、撕裂強度、壓縮長久表現(xiàn)、回彈性、耐油質量變化率、阿克隆磨耗、吸振性、摩擦性能 </p> <p> 3、冶金膠輥用膠料化學性能檢測項目：耐液體性能、耐酸試驗、耐堿試驗、熱空氣老化、耐腐蝕性、導電性、傳熱性、親水性、耐溶劑性 </p> <p> 4、冶金膠輥表面特性檢測項目：脫層、機械損傷、雜質、氣泡、砂眼、表面粗糙度、表面處理。 </p> <p> 5、冶金膠輥其他檢測項目：尺寸公差、膠層厚度、膠層與輥芯黏合強度 </p> <p> 6、冶金膠輥輥芯檢測項目：尺寸、表面質量、壁厚、平衡量、焊縫質量 </p> <p> <br /> 上海冶金膠輥產品介紹膠輥在滿足紡紗質量要求時，必須保持足夠抗繞性、耐油性和優(yōu)良的彈性。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="上海冶金膠輥產品介紹,冶金膠輥"

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。用戶的質量要求高，一般選用免處理。質量要求低，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。</p><p> 三元乙丙再生膠保留了三元乙丙橡膠優(yōu)異的耐高低溫、耐臭氧、耐酸堿、耐老化等性能特點，替代三元乙丙原膠生產的冶金膠輥可以用于傳真機、復印機、打印機等辦公設備，達到分紙、送紙的目的。使用三元乙丙再生膠生產冶金膠輥時，需要再生膠具有均勻的硬度、很高的拉伸強度和扯斷伸長、優(yōu)異的彈性和耐磨性以及化學穩(wěn)定性，保證冶金膠輥中的配合劑不會析出、摩擦后不能有印記。 </p> <p> 使用丁腈再生膠生產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 /> 下班后或長時間不使用，應將膠輥與網紋輥分離開，避免壓傷膠輥而出現(xiàn)傳墨不均勻的線條。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="上海冶金膠輥產品介紹,冶金膠輥"

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向冶金膠輥直徑應該一致，以利于互換，減少工作量，管理方便。但在實際使用中卻發(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，以致產生了很多問題。導向冶金膠輥直徑如果超過30mm,，容易碰網格圈影響質量和生產的順利進行，甚至使加壓不能正常進行，使搖架疲勞加劇，消耗嚴重增加。導向冶金膠輥如果過小，容易使網格圈打頓，出現(xiàn)嚴重的粗細節(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。免處理膠輥應用時，省時、省力、減少污染，受到用戶歡迎。上海冶金膠輥產品介紹</p><p style="text-indent:25px">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,。上海冶金膠輥產品介紹</p><p style="text-indent:25px">在實際生產應用中，由于紡紗品種的不斷變化，器材制造商生產的冶金膠輥膠圈有多種型號，紡紗企業(yè)不可能對每一種型號的冶金膠輥膠圈都熟悉，有的造成了紡紗生產中纖維纏繞冶金膠輥膠圈、冶金膠輥膠圈提前凹心、須條牽伸不開等問題，甚至造成冶金膠輥膠圈損壞，使冶金膠輥膠圈沒有到使用周期而提前報廢，不僅影響紡紗質量，也增加了器材的消耗。冶金膠輥膠圈的硬度是指垂直施加于冶金膠輥膠圈表面作用力的顯示值。在恒定外力作用下，顯示值越大，硬度越高，反之硬度越低。上海冶金膠輥產品介紹</p></p><br
