一、膠輥之間的壓力過(guò)重膠輥之間的壓力重，會(huì)增加膠輥之間的摩擦力，使膠輥升溫發(fā)熱，加重膠輥之間的擠壓膨脹，加速膠輥的老化和變形，加快油墨和水的乳化過(guò)程，這樣不利于油墨的傳遞。解決的方法就是：膠輥之間的壓力應(yīng)該和接觸版面的壓力基本一致。經(jīng)驗(yàn)是用一塊1500絲，3cm寬的塞片插試膠輥之間，能夠感到有一定緊力就行。擦洗后，再用干凈的布擦一遍然后把膠輥裝到機(jī)器上，以利下次使用。二、膠輥表面晶化的處理表面晶化封閉了膠輥表面的毛細(xì)孔，會(huì)使膠輥失去親墨的作用，造成油墨的傳遞布均勻，容易出現(xiàn)油墨的乳化。解決的辦法就是：把機(jī)器上的膠輥卸下來(lái)，用架子放平，拿布團(tuán)粘煤油和浮石粉，用力均勻地擦膠輥的表面，把膠輥表面晶化層擦掉，顯出原來(lái)膠輥的橡膠顏色，再用洗車水或汽油把殘留在膠輥上的煤油和浮石粉清洗干凈，重新安裝和調(diào)節(jié)好膠輥的壓力。三、膠輥上的軸承的保養(yǎng)在機(jī)器的高速運(yùn)轉(zhuǎn)中，膠輥上軸承磨損是很明顯的，特別是操作工平時(shí)堆軸承的保養(yǎng)布注意，那磨損就更厲害。膠輥的軸承受到一定程度的損壞后，就會(huì)產(chǎn)生膠輥的跳動(dòng)摩擦和擠壓，減短膠輥的使用壽命。并會(huì)使到印出的產(chǎn)品有“墨、水杠”現(xiàn)象。所以要求操作工每周要把膠輥拿下來(lái)，給軸承打上黃油。</p><p> 橡膠輥是有金屬芯和表皮彈性橡膠層制作而成。它具有一定彈性同時(shí)，要耐介質(zhì)和耐磨等特性是金屬滾無(wú)法代替的，目前一般在造紙、印刷、印染、打字、收割機(jī)、礱谷輥、收銀機(jī)、皮革以及采礦等很多行業(yè)看到橡膠輥的應(yīng)用。但在使用過(guò)程中難免出現(xiàn)一些問(wèn)題，下面具體來(lái)介紹一下。一、熱老化膠輥受熱會(huì)加速脫硫，產(chǎn)生熱老化，使表面發(fā)粘，變軟，甚至出現(xiàn)裂縫成桔紋狀。此時(shí)膠輥只能更換。二、膠體掉塊油墨在膠體表面?zhèn)鬟f過(guò)程中早期干燥，干結(jié)的墨膜由于其延展性下降，在滾壓的過(guò)程中，會(huì)使得膠體表面隨著墨膜的龜裂而破壞，從而造成膠體掉塊發(fā)生。油墨發(fā)生早期干燥的原因主要是油墨中添加了干燥劑，印刷了油墨干性較快的油墨（例如用于鋁箔紙的POP油墨），沒(méi)有按要求清洗墨輥，使得油墨在長(zhǎng)期使用過(guò)程中在膠輥上發(fā)生了干結(jié)現(xiàn)象。輥加工過(guò)程中溫度過(guò)高，表面易碳化，短時(shí)印刷就會(huì)出現(xiàn)掉塊現(xiàn)象。過(guò)重的印刷壓力調(diào)節(jié)，當(dāng)機(jī)器空轉(zhuǎn)時(shí)，若空轉(zhuǎn)保護(hù)措施不當(dāng)或不及時(shí)，也會(huì)加速輥體表面的破壞。發(fā)生掉塊的膠輥可以更換解決由此造成的印刷故障。三、表面釉化在印刷過(guò)程中，油墨中的連接料中的有機(jī)物無(wú)機(jī)物，以及潤(rùn)版液中的親水膠體，紙張中的脫落的填料，涂料會(huì)在墨輥表面形成一層“亮膜”。膠輥之間的壓力過(guò)重膠輥之間的壓力重。</p><div

膠輥用膠料種類從天然橡膠、合成橡膠到特種材料多達(dá)10余種以上，含膠率為25%～85%，硬度為土（0～90）度，跨越極大范圍。因此，如何使這些膠料混煉均勻已成為一大難題。常規(guī)的方法是采用開(kāi)煉機(jī)以多種母煉膠的形式進(jìn)行混煉加工。近些年來(lái)，企業(yè)更多地改用嚙合式密煉機(jī)，以分段混煉的方式制取膠料。膠料達(dá)到均勻混煉之后還要用濾膠機(jī)進(jìn)行濾膠，消除膠料內(nèi)的雜質(zhì)。然后再用壓延機(jī)、壓出機(jī)、貼合機(jī)制成沒(méi)有氣泡和雜質(zhì)的膠片或膠條，供膠輥成型用。在成型之前，對(duì)這些膠片、膠條還要進(jìn)行嚴(yán)格的外觀檢查，限定停放期，保持新鮮表面并防止粘連和擠壓變形。因?yàn)槟z輥大部分為非模壓制品，一旦表面橡膠存在雜質(zhì)和氣泡，在硫化后對(duì)表面進(jìn)行研磨時(shí)即有可能出現(xiàn)砂眼，由此將導(dǎo)致整個(gè)膠輥出現(xiàn)超標(biāo)返修，甚至報(bào)廢。02成型膠輥成型主要是在金屬芯上粘貼包覆橡膠，有包貼法、擠出法、模壓法、注壓法和注射法等。目前國(guó)內(nèi)主要以機(jī)械或手工粘貼成型為主，國(guó)外多數(shù)已實(shí)現(xiàn)了機(jī)械自動(dòng)化。大中型膠輥基本上采用仿形擠出，用壓出膠片連續(xù)粘貼成型或擠出膠條連續(xù)纏繞成型的方式生產(chǎn)。同時(shí)，在成型過(guò)程中以微機(jī)自動(dòng)控制其規(guī)格尺寸和外觀形狀，有的也可用壓出機(jī)直角和異形擠出的方法進(jìn)行成型。上海橡膠輥</p></p><br
