使得墨輥表面玻璃化，傳墨性能下降。四、膠輥膨脹除了受熱的原因外，主要的原因是使用了不當(dāng)?shù)那逑磩?，使得膠體發(fā)生了溶脹。解決辦法是選擇適當(dāng)?shù)那逑磩ǔＪ鼓z輥溶脹的有機(jī)溶劑：MEK甲基乙醛酮、三氯乙烯、**、環(huán)甲烷、香蕉水；不溶脹的有機(jī)溶劑：酒精、煤油、輕油、輥清洗劑）。五、周向條痕除了結(jié)晶化合物會(huì)引起類(lèi)似的周向條痕外，硬質(zhì)的墨輥上干結(jié)的墨皮，垃圾會(huì)在運(yùn)轉(zhuǎn)過(guò)程中劃傷軟質(zhì)膠輥的表面而形成周向條痕，此時(shí)必須使用死墨去除劑去除干結(jié)的墨皮。六、水斗輥沾墨鉻輥表面吸附潤(rùn)版液后能使油墨充分隔離，但是過(guò)量的潤(rùn)版液，潤(rùn)版液的酸性過(guò)強(qiáng)都會(huì)加大油墨的乳化，乳化后的油墨會(huì)隨著回水路返回到水斗輥上，水斗輥上吸附油墨后會(huì)造成潤(rùn)版不良，局部水小的故障。必須及時(shí)水斗輥上的油墨，同時(shí)調(diào)節(jié)潤(rùn)版液量的大小和其成分。七、水輥兩頭濺水印刷過(guò)程中靠版水輥兩頭有水滴滴落在承印物印刷面上，造成這種情況的原因有：水斗輥與計(jì)量輥的長(zhǎng)度差超過(guò)允許范圍，長(zhǎng)度差大于了；水斗輥的角部處理好，其角部圓度大于了。還需注意的是橡膠輥包膠的加工周期大約是7-10天，這未包含物流時(shí)間，膠輥使用方應(yīng)該算好時(shí)間，不要影響替換和檢修，在開(kāi)展正式膠輥包膠前。安徽橡膠輥廠家解決的辦法就是：把機(jī)器上的膠輥卸下來(lái)。</p><div

車(chē)間環(huán)境對(duì)橡膠輥的影響在悶熱和潮濕的天氣和來(lái)自周?chē)幕覊m飛揚(yáng)的環(huán)境生產(chǎn)中，機(jī)器的高速運(yùn)轉(zhuǎn)使到橡膠輥的表面溫度不斷升高，橡膠輥在發(fā)熱膨脹，加大橡膠輥的磨擦，這樣會(huì)使得橡膠輥的使用壽命縮短。所以在有條件的工廠里，膠印插件要求安裝空調(diào)，保持車(chē)間整潔、干凈，使得機(jī)器在良好的環(huán)境中生產(chǎn)運(yùn)轉(zhuǎn)，只有在良好的車(chē)間環(huán)境里生產(chǎn)，才會(huì)生產(chǎn)出***的產(chǎn)品來(lái)。橡膠輥之間的壓力過(guò)重橡膠輥之間的壓力重，會(huì)增加橡膠輥之間的摩擦力，使橡膠輥升溫發(fā)熱，加重橡膠輥之間的擠壓膨脹，加速橡膠輥的老化和變形，加快油墨和水的乳化過(guò)程，這樣不利于油墨的傳遞。需要注意的是橡膠輥之間的壓力應(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寬的塞片插試橡膠輥之間，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橡膠輥裝到機(jī)器上，以利下次使用。橡膠輥表面晶化的處理表面晶化封閉了橡膠輥表面的毛細(xì)孔，會(huì)使橡膠輥失去親墨的作用，造成油墨的傳遞不均勻，容易出現(xiàn)油墨的乳化。解決的辦法是把機(jī)器上的橡膠輥卸下來(lái)，用架子放平，拿布團(tuán)粘煤油和浮石粉，用力均勻地擦橡膠輥的表面，把橡膠輥表面晶化層擦掉，顯出原來(lái)橡膠輥的橡膠顏色。</p><p>
