氟是促進封孔的元素。（1）封孔時間對封孔質(zhì)量的影響封孔時間直接決定封孔質(zhì)量。封孔時間是封孔劑封孔能力的體現(xiàn)，受溫度、pH值、封孔劑成分和濃度、添加劑成分和濃度的影響較大。在同等條件下，與氟化鎳相比，氟鈦酸的封孔能力在三倍左右。即氟鈦酸的封孔時間是氟化鎳的1/3。若氧化膜的厚度為15μm，氟化鎳需要封孔15分鐘，氟鈦酸需5分鐘左右。（2）封孔溫度對封孔質(zhì)量的影響根據(jù)不同溫度下的封孔試驗，可得到氟鈦酸封孔質(zhì)量與溫度的變化規(guī)律。當溫度處于15-20℃時，封孔質(zhì)量較好；當溫度升高時，離子擴散速度加快，水解速度加快，F(xiàn)-濃度提高，與氧化膜反應加快，生成的Ti(OH)4多，封孔速度提高；溫度太低時，F(xiàn)-濃度低，與氧化膜反應弱，生成的Ti(OH)4少，封孔效果則較差。實驗表明，當其他控制指標在工作范圍時，氟鈦酸的封孔溫度與封孔速度的關系為：溫度在15-20℃時，封孔速度約1μm/min；溫度在20-25℃時，封孔速度約2μm/min；溫度在25-30℃時，封孔速度約3μm/min。此時，可根據(jù)氧化膜性質(zhì)、厚度、封孔溫度等確定封孔時間。（3）pH值對封孔質(zhì)量的影響根據(jù)pH值對封孔質(zhì)量的影響試驗，可得pH值對封孔質(zhì)量的影響規(guī)律。隨槽液pH值的上升，按（2）式，氟鈦酸水解增加。浙江低溫封孔劑封孔劑哪家性價比高，詳情可以訪問百事德，有需求的不要錯過哦！</p><div

1技術(shù)領域本發(fā)明涉及鋁合金陽極氧化封孔工藝，屬于鋁加工領域。2技術(shù)背景目前，我國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)過程每年產(chǎn)生含鎳廢水達600萬噸。排出廢水中的鎳常以鹵化物、硝酸鹽、鹽以及某些有機和無機絡合物的形式溶解于水。鋁合金陽極氧化膜的封孔，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、有機聚合物涂層封孔（有機酸或電泳漆封孔）和其他無鎳封孔等工藝。我國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，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。</p><p>
