（1）工作溫度上升。橡膠體工作中產(chǎn)生的熱量與工作速度，上海冶金膠輥生產(chǎn)線、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(guò)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)，上海冶金膠輥生產(chǎn)線，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，上海冶金膠輥生產(chǎn)線。 </p> <p> <br />

冶金膠輥結(jié)構(gòu)一般有單層（現(xiàn)在已經(jīng)淘汰）、雙層、鋁襯和多層四種，多層不多見(jiàn)，目前市面*見(jiàn)歐瑞康公司研制的一種冶金膠輥，主要是為了增加冶金膠輥彈性在靠近鋁層包覆一層薄薄的較低硬度（62度）的丁氰橡膠，外層再使用65度或者75度的冶金膠輥包覆。在選用過(guò)程中，一般質(zhì)量要求高使用鋁襯，其余使用雙層。耐壓要求高使用鋁襯，耐壓要求低則使用雙層。結(jié)構(gòu)選用誤區(qū)主要體現(xiàn)在兩個(gè)方面，要么是全部使用雙層冶金膠輥，要么是全部使用鋁襯冶金膠輥，而不根據(jù)企業(yè)實(shí)際要求進(jìn)行選擇。這種錯(cuò)誤認(rèn)識(shí)主要是緣于未能把握結(jié)構(gòu)選用原則所致。 </p> <p> <br /> 上海冶金膠輥費(fèi)用軸承選用原則主要是根據(jù)膠輥結(jié)構(gòu)的區(qū)分，選用不同規(guī)格的軸承，不能混用。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

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(zhǎng)。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(guò)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。</p><p style="text-indent:25px">從理論上講，鋁襯冶金膠輥和雙層冶金膠輥各有自己的優(yōu)勢(shì)，鋁襯冶金膠輥在耐壓性、穩(wěn)定性和制作的簡(jiǎn)便性等都要優(yōu)于雙層冶金膠輥，但價(jià)格則比雙層貴一些。由于雙層走熟期較長(zhǎng)、套差大存在內(nèi)應(yīng)力、容易老化中凹，因此我們一般推薦使用鋁襯冶金膠輥，但對(duì)質(zhì)量要求不高或者后冶金膠輥，出于成本考慮，我們認(rèn)為還是雙層冶金膠輥更為適合。冶金膠輥選用主要考慮搭配原則。對(duì)平面牽伸來(lái)說(shuō)，冶金膠輥硬度要求比前冶金膠輥高5-10度，直徑要求比前冶金膠輥小0.5mm~1.5mm,。由于后區(qū)速度低，一般冶金膠輥檔次比前冶金膠輥略低。但對(duì)V型牽伸來(lái)說(shuō)，直徑建議能大于前擋冶金膠輥，硬度要求和檔次要求則和平面牽伸相同。把握好膠輥上車(chē)前、后的質(zhì)量關(guān)，加強(qiáng)檢查考核力度。</p><div

由于冶金膠輥的作用是把網(wǎng)紋輥表面的油墨擠掉，因此其壓力可以略大些。如果使用的網(wǎng)紋輥線數(shù)偏高，在印刷色塊和大的文字時(shí)，傳墨量不夠時(shí)，操作者常常采用加大冶金膠輥與網(wǎng)紋輥間隙的方法來(lái)增加供墨量。這樣冶金膠輥與網(wǎng)紋輥之間就產(chǎn)生了間隙。間隙的產(chǎn)生就失去了網(wǎng)紋輥定量供墨的作用。因此使用網(wǎng)紋輥一定要有“定量”供墨的概念，不能用間隙來(lái)調(diào)整傳墨量，有間隙墨量就控制不好，色塊印不平實(shí)，會(huì)出現(xiàn)條痕;網(wǎng)線版會(huì)產(chǎn)生色差。如果冶金膠輥與網(wǎng)紋輥在正常接觸狀態(tài)下，網(wǎng)紋輥網(wǎng)墻上的油墨仍不能擠掉，則說(shuō)明油墨的粘度過(guò)高，應(yīng)調(diào)整油墨粘度。 </p> <p> <br /> </p> <p> <br /> 軸承加油的油脂型號(hào)、加油機(jī)的擠壓次數(shù)是減少膠輥膠圈污染、損傷、損壞、龜裂、破裂的關(guān)鍵。上海冶金膠輥生產(chǎn)線</p><p
