你知道下面的這些現(xiàn)象是如何產(chǎn)生的嗎？印刷版面有明顯條紋現(xiàn)象，印刷版面產(chǎn)生拖花現(xiàn)象，兩色需要疊印時(shí)很困難，到底是什么原因出現(xiàn)的這些問(wèn)題，是機(jī)器出的故障還是操作不當(dāng)？再說(shuō)一個(gè)我經(jīng)?？吹降默F(xiàn)象，上海原裝橡膠輥，經(jīng)常能看到印刷機(jī)操作人員調(diào)機(jī)，上海原裝橡膠輥，尤其是調(diào)印刷含墨量，印刷實(shí)地色塊還好一點(diǎn)，如果是印細(xì)小的字體或網(wǎng)點(diǎn)，操作人員常用的方法是將膠輥與網(wǎng)紋輥調(diào)至擠壓緊無(wú)法再調(diào)動(dòng)的狀態(tài)。這種方法對(duì)不對(duì)呢？我們處理過(guò)很多膠輥和網(wǎng)紋輥軸頭磨損脫焊斷裂，軸承碎裂的狀況。我們先說(shuō)橡膠輥與網(wǎng)紋輥的接觸壓力。相對(duì)于網(wǎng)紋輥與印版輥筒、印版輥筒與壓印輥筒的壓力來(lái)說(shuō)，由于膠輥的作用是把網(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)，墨量不夠，因此操作者常常采用加大橡膠輥與網(wǎng)紋輥間隙的方法來(lái)增加供墨量。這樣的操作方式不能說(shuō)不對(duì)，但是卻失去了網(wǎng)紋輥定量供墨的作用。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)整墨量，有間隙墨量就控制不好，實(shí)地印不平服，會(huì)出現(xiàn)燈芯絨狀條痕；網(wǎng)線版會(huì)產(chǎn)生色差，上海原裝橡膠輥。如果膠輥與網(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)明水墨的粘度過(guò)高，應(yīng)調(diào)整水墨粘度。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。上海原裝橡膠輥</p><div

以聚氨酯彈性體（PUR）為的液體橡膠在膠輥生產(chǎn)中發(fā)展很快，并為之開辟了材料和工藝**的新途徑。它采用澆注形式，把復(fù)雜的成型操作與笨重的硫化設(shè)備甩掉，使膠輥生產(chǎn)工藝大為簡(jiǎn)化。不過(guò)，大問(wèn)題是由于必須使用模具，對(duì)于大型膠輥特別是單個(gè)產(chǎn)品來(lái)說(shuō)，導(dǎo)致生產(chǎn)成本大幅提高，給推廣使用帶來(lái)了很大困難。為解決這一難題，近年開始出現(xiàn)無(wú)模制造的PUR膠輥新工藝。它以聚氧化丙烯醚多元醇(TDIOL)、聚四氫呋喃醚多元醇(PIMG)和二苯甲烷二異氰酸酯(MDl)為原料，混合攪拌之后快速反應(yīng)，定量地澆注到緩慢旋轉(zhuǎn)的膠輥金屬芯上，一步一步實(shí)現(xiàn)邊澆注邊固化，后形成膠輥。這種工藝不*流程短，機(jī)械化、自動(dòng)化程度高，而且省去了笨重的模具，可隨意根據(jù)要求生產(chǎn)各種規(guī)格尺寸的膠輥，使成本大幅度下降，現(xiàn)已成為PUR膠輥的主要發(fā)展方向。另外，在世界各地用液體硅橡膠制造辦公自動(dòng)化設(shè)備方面使用的微型精細(xì)膠輥也發(fā)展很快。它們分為加熱固化(LTV)和室溫固化(RTV)兩大類，所用設(shè)備也同上面的PUR不同，形成另一類澆注形式。在這里，關(guān)鍵的問(wèn)題是如何控制并降低膠料粘度，使之保持一定的壓力和擠出速度。四、表面處理表面處理是膠輥生產(chǎn)后也是關(guān)鍵的一道工序。</p><p> 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。并會(huì)使到印出的產(chǎn)品有“墨、水杠”現(xiàn)象。</p><div
