7）雜質(zhì)離子對(duì)封孔質(zhì)量的影響在生產(chǎn)過(guò)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(yáng)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(guò)低時(shí)，可用氨水調(diào)節(jié)pH值至，不要用氫氧化鈉來(lái)調(diào)節(jié)，這樣可有效阻止Na+消耗螯合劑。影響鋁合金無(wú)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(gè)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(shí)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(yàn)表明，鋁合金無(wú)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(shí)間5-15min，PH值。氟鈦酸體系無(wú)鎳封孔新技術(shù)有以下創(chuàng)新點(diǎn)：1、采用氟鈦酸作為封孔劑的主要成分，建立了無(wú)鎳封孔新藥劑配方及工藝，從源頭徹底消除了鎳鹽對(duì)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(wèn)題；3、采用緩蝕技術(shù)，降低溶鋁量，減少表面上粉，延長(zhǎng)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><p>

1技術(shù)領(lǐng)域本發(fā)明涉及鋁合金陽(yáng)極氧化封孔工藝，屬于鋁加工領(lǐng)域。2技術(shù)背景目前，我國(guó)建筑鋁合金封孔主要采用冷封孔工藝（常溫封孔）和中溫封孔工藝（50-60℃封孔），鎳鹽是封孔藥劑的主要成分（氟化鎳或醋酸鎳）。鋁合金封孔后，需要經(jīng)過(guò)兩道以上的水洗槽水洗，清洗表面殘留的含鎳封孔藥液，方可下線包裝。這種封孔處理方式，產(chǎn)生如下兩方面的金屬鎳化合物污染：一是清洗水中的鎳污染，二是鋁合金表面的鎳污染。目前的陽(yáng)極氧化封孔工藝，首先產(chǎn)生的是清洗廢水的鎳污染。以常溫氟化鎳封孔為例，每處理1噸鋁合金，需要消耗4噸工藝用水，消耗，產(chǎn)生4噸含鎳廢水，*廣東省，鋁表面封孔生產(chǎn)過(guò)程每年產(chǎn)生含鎳廢水達(dá)600萬(wàn)噸。排出廢水中的鎳常以鹵化物、硝酸鹽、鹽以及某些有機(jī)和無(wú)機(jī)絡(luò)合物的形式溶解于水。鋁合金陽(yáng)極氧化膜的封孔，涵蓋熱封孔工藝（熱-水合封孔工藝）、冷封孔工藝、中溫封孔工藝、有機(jī)聚合物涂層封孔（有機(jī)酸或電泳漆封孔）和其他無(wú)鎳封孔等工藝。我國(guó)的建筑鋁合金主要采用冷封孔工藝、中溫封孔工藝和電泳漆封孔工藝。近年來(lái)，為了滿足較厚氧化膜性能需求，中溫封孔工藝得到了較快發(fā)展。（1）熱-水合封孔工藝熱-水合封孔工藝包括沸水封孔和高溫水蒸氣封孔。封孔劑哪家好，詳情可以訪問(wèn)百事德，有需求的不要錯(cuò)過(guò)哦！四川陽(yáng)極封孔劑價(jià)格</p><p

在以氟鈦酸為封孔主要成分的無(wú)鎳封孔液新配方條件下，工藝參數(shù)有很大的變化：封孔溫度15-35℃封孔速度1-3um/min槽液PHF-濃度氟鈦酸自帶，不專門(mén)限制（7）H2TiF6(50%)濃度比較式(6)與(7)，氟鈦酸的封孔能力比氟化鎳強(qiáng)，封孔溫度下限由25℃拓寬至15℃，封孔速度1um/min提高至3um/min，槽液，但范圍拓寬。由于含大量螯合劑，新配方對(duì)水質(zhì)要求不高，開(kāi)槽用自來(lái)水即可，所含Ca2+、Mg2+可被螯合劑完全屏蔽。氟化鎳封孔的F-濃度為，分子結(jié)構(gòu)中F-不夠，需要額外補(bǔ)氟；氟鈦酸分子結(jié)構(gòu)中，氟含量過(guò)高，為此，配方中專門(mén)設(shè)置緩蝕劑，降低氟的腐蝕能力，故F-按式（2），自動(dòng)水解平衡，無(wú)需檢測(cè)和控制。氟化鎳封孔的Ni2+濃度為，氟鈦酸槽液中鈦不是以Ti4+存在，而是以Ti(OH)3F32-+Ti(OH)2F42-+Ti(OH)F52-存在，故選用H2TiF6(50%)濃度。式（1）-（5）顯示封孔動(dòng)力學(xué)的全過(guò)程。式（1）表明氟鈦酸在槽液中電離成2H++TiF62-；式（2）表明氟鈦酸根在槽液中水解成Ti(OH)3F32-+Ti(OH)2F42-+Ti(OH)F52-，并釋放6H++6F-；式（4）表明F-在氧化膜微孔反應(yīng)，釋放出OH-，提高微孔中的pH值；式（3）表面在氧化膜微孔中，pH值的升高，Ti(OH)3F32-進(jìn)一步水解，生成封孔物資Ti(OH)4，完成封孔。由此可見(jiàn)。常州鋁材封孔劑廠家</p><p
