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(zhuān)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(zhuān)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)。</p><p> 1）3TiF62-+6H2O=Ti(OH)3F32-+Ti(OH)2F42-+Ti(OH)F52-+6H++6F(氟鈦酸水解)（2）按（2）式，氟鈦酸的水溶液不穩(wěn)定，易水解成一羥基、二羥基和三羥基氟鈦酸根，同時(shí)釋放出H+和F-，使槽液pH值下降，F(xiàn)-濃度增加；若提高pH值，按（2）式，反應(yīng)向右邊移動(dòng)，當(dāng)pH值大于，三羥基氟鈦酸進(jìn)一步水解,出現(xiàn)渾濁沉淀：Ti(OH)3F32-+H2O=Ti(OH)4↓+H++3F-（氟鈦酸分解，析出氫氧化鈦）（3）當(dāng)槽液中放入含氧化膜的鋁合金時(shí)，F(xiàn)-與氧化膜反應(yīng)：Al2O3+12F-+3H2O=2AlF63-+6OH-（氧化膜被溶解，pH值升高）（4）2AlF63-+Al2O3+3H2O=2Al2(OH)3F3↓+6F-（鋁材上粉）（5）為了保證鋁陽(yáng)極氧化后長(zhǎng)期使用，必須進(jìn)行封孔處理。封孔的目的是為了提高鋁材的耐蝕性、其表面抗污染能力及其著色膜的色澤度和耐光、耐候性，因此封孔是十分重要的技術(shù)環(huán)節(jié)。目前國(guó)內(nèi)外普遍使用的工藝是以氟化鎳為主體的常溫封孔，其封孔工藝條件為：封孔溫度25-35℃封孔速度1um/min槽液PH所用水的潔凈度去離子水F-濃度Ni2+濃度（6）這些因素對(duì)其封孔質(zhì)量的影響非常大，且不好控制，稍加不慎，無(wú)法保證鋁材的封孔質(zhì)量，影響生產(chǎn)。除含鎳封孔液造成水污染外，手機(jī)、空調(diào)、電視、冰箱、電腦、相機(jī)等等。封孔劑，就選仙桃市百事德化工有限責(zé)任公司，用戶(hù)的信賴(lài)之選，有需要可以聯(lián)系我司哦！</p><div
