1.與普(pu)通(tong)油(you)墨(mo)相比,紫(zi)外(wai)(wai)(wai)線(xian)(xian)(xian)(xian)油(you)墨(mo)的(de)應用(yong)(yong)(yong)對印(yin)(yin)刷(shua)(shua)設(she)(she)備(bei)有一定(ding)的(de)要(yao)求。例(li)如,目(mu)前許多印(yin)(yin)刷(shua)(shua)企業通(tong)過在(zai)普(pu)通(tong)膠(jiao)(jiao)印(yin)(yin)機(ji)(ji)上(shang)安裝紫(zi)外(wai)(wai)(wai)線(xian)(xian)(xian)(xian)固化(hua)裝置來實現紫(zi)外(wai)(wai)(wai)線(xian)(xian)(xian)(xian)印(yin)(yin)刷(shua)(shua),但(dan)這種設(she)(she)備(bei)改造(zao)方法存在(zai)紫(zi)外(wai)(wai)(wai)線(xian)(xian)(xian)(xian)油(you)墨(mo)腐蝕性強等問題,可能導(dao)(dao)致普(pu)通(tong)膠(jiao)(jiao)輥(gun)。橡(xiang)(xiang)膠(jiao)(jiao)布(bu)膨脹,影響(xiang)(xiang)印(yin)(yin)刷(shua)(shua)壓(ya)力(li)的(de)穩定(ding)性,甚至導(dao)(dao)致橡(xiang)(xiang)膠(jiao)(jiao)輥(gun)剝落或表面破裂(lie)。因(yin)此(ci)(ci),紫(zi)外(wai)(wai)(wai)線(xian)(xian)(xian)(xian)油(you)墨(mo)印(yin)(yin)刷(shua)(shua)對橡(xiang)(xiang)膠(jiao)(jiao)輥(gun)和橡(xiang)(xiang)膠(jiao)(jiao)布(bu)的(de)要(yao)求很(hen)高,一般需要(yao)使(shi)用(yong)(yong)(yong)紫(zi)外(wai)(wai)(wai)線(xian)(xian)(xian)(xian)印(yin)(yin)刷(shua)(shua)專(zhuan)用(yong)(yong)(yong)橡(xiang)(xiang)膠(jiao)(jiao)輥(gun)和橡(xiang)(xiang)膠(jiao)(jiao)布(bu)。普(pu)通(tong)紙牙在(zai)紫(zi)外(wai)(wai)(wai)線(xian)(xian)(xian)(xian)照(zhao)射下,牙齒(chi)部分(fen)會加熱變形,從而影響(xiang)(xiang)印(yin)(yin)刷(shua)(shua)精度。因(yin)此(ci)(ci),印(yin)(yin)刷(shua)(shua)單元上(shang)的(de)紙牙必須更換為紫(zi)外(wai)(wai)(wai)線(xian)(xian)(xian)(xian)印(yin)(yin)刷(shua)(shua)專(zhuan)用(yong)(yong)(yong)紙牙。紫(zi)外(wai)(wai)(wai)線(xian)(xian)(xian)(xian)油(you)墨(mo)粘度高。腐蝕性強,不僅容(rong)易(yi)使(shi)普(pu)通(tong)墨(mo)斗開(kai)裂(lie)損(sun)(sun)壞(huai),導(dao)(dao)致紫(zi)外(wai)(wai)(wai)線(xian)(xian)(xian)(xian)墨(mo)流(liu)入墨(mo)齒(chi)傳(chuan)動(dong)(dong)機(ji)(ji)構(gou),導(dao)(dao)致墨(mo)齒(chi)傳(chuan)動(dong)(dong)機(ji)(ji)構(gou)阻力(li)大,而且容(rong)易(yi)損(sun)(sun)壞(huai)墨(mo)輥(gun)傳(chuan)動(dong)(dong)機(ji)(ji)構(gou)。一旦出現這些故障(zhang),處理起來就會更麻煩。當紫(zi)外(wai)(wai)(wai)線(xian)(xian)(xian)(xian)油(you)墨(mo)流(liu)入墨(mo)齒(chi)傳(chuan)動(dong)(dong)機(ji)(ji)構(gou)時(shi),必須立即停止(zhi)并拆(chai)(chai)卸(xie)墨(mo)齒(chi)傳(chuan)動(dong)(dong)機(ji)(ji)構(gou),否則很(hen)難清洗。但(dan)由于墨(mo)齒(chi)傳(chuan)動(dong)(dong)機(ji)(ji)構(gou)內部件設(she)(she)計緊密,拆(chai)(chai)卸(xie)麻煩,特別是內圓柱彈性銷體(ti)積小,拆(chai)(chai)卸(xie)過程中容(rong)易(yi)損(sun)(sun)壞(huai),對印(yin)(yin)刷(shua)(shua)設(she)(she)備(bei)造(zao)成二次損(sun)(sun)壞(huai)。因(yin)此(ci)(ci),使(shi)用(yong)(yong)(yong)質量(liang)可靠(kao)的(de)墨(mo)斗片是避(bi)免上(shang)述故障(zhang)的(de)最重要(yao)前提。此(ci)(ci)外(wai)(wai)(wai),操作人(ren)員還需要(yao)加強印(yin)(yin)刷(shua)(shua)設(she)(she)備(bei)的(de)日常維護,徹(che)底清潔,使(shi)用(yong)(yong)(yong)合格的(de)配件和原材(cai)料(liao)耗材(cai)。
2.上述關于UV油墨固化的存儲條件的要求。印刷穩定性需要一個重要的前提,即良好的油墨存儲條件。UV油墨的最佳儲存溫度應控制在20~25℃,以避免陽光照射。最佳相對濕度應控制在55%~65%。密封存放,避免灰塵混合,UV油墨存放倉庫應保持恒溫恒濕。同時,還應注意,UV油墨儲存倉庫應遠離火源和熱源,以防發生事故。UV油墨的儲存和使用管理也應遵循先入先出的原則,即先購買的UV油墨應先使用,防止UV油墨因儲存時間長而影響其使用質量。剩余的UV油墨必須在黑暗中密封。紫外線油墨不宜長期保存,保證在保質期前使用,最長保質期不得超過一年,否則會影響印刷質量。剩余的紫外線油墨必須密封并儲存在黑暗中。紫外線油墨不得長期保存,嚴重影響印刷質量。
簡而言之,影響UV油墨使用的因素是密切相關的。印刷企業必須從多個角度考慮UV油墨的應用,消除問題,充分發揮UV油墨的優勢。分散劑_觸變劑_氟硅聚合物流平劑_散劑。主要用于工業涂料、油墨、密封膠、電子材料等行業。引領核心技術,打造高端添加劑品牌。
