7）雜質(zhì)離子對封孔質(zhì)量的影響在生產(chǎn)過程中不斷帶進(jìn)雜質(zhì)離子，造成雜質(zhì)的積累，如NH4+、Na+、K+、Ca2+、Mg2+等陽離子增多，螯合劑消耗加快。因此，把好清洗關(guān)至關(guān)重要。另外，槽液pH過低時，可用氨水調(diào)節(jié)pH值至，不要用氫氧化鈉來調(diào)節(jié)，這樣可有效阻止Na+消耗螯合劑。影響鋁合金無鎳封孔質(zhì)量的因素很多，主要有氟鈦酸濃度、緩蝕劑濃度和螯合劑濃度，這三個因素是決定鋁合金封孔質(zhì)量的關(guān)鍵；槽液的pH值、溫度和封孔時間是影響鋁合金封孔質(zhì)量的重要因素；而提高槽液的潔凈度、減小雜質(zhì)的含量是鋁合金封孔質(zhì)量的重要保證。試驗表明，鋁合金無鎳封孔劑的生產(chǎn)工藝條件應(yīng)為：氟鈦酸（50wt.%）濃度區(qū)間為，緩蝕劑的濃度區(qū)間為1-3g/L，螯合劑濃度區(qū)間為1-3g/L；封孔速度1-3um/min，溫度15-35℃，時間5-15min，PH值。氟鈦酸體系無鎳封孔新技術(shù)有以下創(chuàng)新點：1、采用氟鈦酸作為封孔劑的主要成分，建立了無鎳封孔新藥劑配方及工藝，從源頭徹底消除了鎳鹽對水質(zhì)的污染；2、采用螯合技術(shù)，解決了封孔液分解沉淀問題；3、采用緩蝕技術(shù)，降低溶鋁量，減少表面上粉，延長槽液壽命；4、采用氟鈦酸作為封孔劑的主要成分，封孔速度是鎳鹽的兩倍以上，提高了生產(chǎn)效率。</p><div

本發(fā)明屬于金屬或合金材料制備工藝技術(shù)領(lǐng)域，具體涉及一種可長期儲存陽極氧化未封孔金屬印刷材料及其制備方法和應(yīng)用。背景技術(shù)：金屬或合金經(jīng)過常規(guī)的陽極氧化處理后形成的陽極氧化層中存在大多數(shù)的微孔，這些微孔的存在是用于將印刷時的噴出的墨水吸入孔中，進(jìn)而完成對陽極氧化金屬或合金的印刷。常規(guī)金屬或者合金在經(jīng)過陽極氧化處理后，陽極氧化層暴露在含有水分子和氧氣的環(huán)境中，此種環(huán)境會使經(jīng)陽極氧化處理后的金屬或者合金的陽極氧化層表面與水分子和氧氣產(chǎn)生化學(xué)反應(yīng)，在陽極氧化層上會形成氫氧化物。當(dāng)氫氧化物侵入到微孔中后，會直接引起微孔孔徑變小，或者是引起微孔堵塞。之后隨著反應(yīng)時間的延續(xù)，多數(shù)陽極氧化層中的微孔均會處于被堵塞的狀態(tài)。微孔出現(xiàn)孔徑變小或是引發(fā)堵塞，會直接對陽極氧化金屬或者合金對墨水的吸入效率及吸入量產(chǎn)生很大的影響，進(jìn)而影響陽極氧化金屬或者合金的成像質(zhì)量問題，這也是目前常用的陽極氧化金屬或者合金中經(jīng)常出現(xiàn)染料擴(kuò)散不均勻和顏色混亂的原因所在。對于上述問題的出現(xiàn)，是由于現(xiàn)有的技術(shù)中通過對金屬或者合金進(jìn)行陽極氧化處理后，此時微孔保持開啟狀態(tài)，因此必須要在當(dāng)時的環(huán)境下馬上進(jìn)行著色印刷，之后將微孔封閉后方可出廠。</p></p><br
