氟是促進(jìn)封孔的元素。（1）封孔時(shí)間對(duì)封孔質(zhì)量的影響封孔時(shí)間直接決定封孔質(zhì)量。封孔時(shí)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(shí)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(duì)封孔質(zhì)量的影響根據(jù)不同溫度下的封孔試驗(yàn)，可得到氟鈦酸封孔質(zhì)量與溫度的變化規(guī)律。當(dāng)溫度處于15-20℃時(shí)，封孔質(zhì)量較好；當(dāng)溫度升高時(shí)，離子擴(kuò)散速度加快，水解速度加快，F(xiàn)-濃度提高，與氧化膜反應(yīng)加快，生成的Ti(OH)4多，封孔速度提高；溫度太低時(shí)，F(xiàn)-濃度低，與氧化膜反應(yīng)弱，生成的Ti(OH)4少，封孔效果則較差，徐州鋁合金封孔劑封閉。實(shí)驗(yàn)表明，當(dāng)其他控制指標(biāo)在工作范圍時(shí)，氟鈦酸的封孔溫度與封孔速度的關(guān)系為：溫度在15-20℃時(shí)，封孔速度約1μm/min；溫度在20-25℃時(shí)，徐州鋁合金封孔劑封閉，封孔速度約2μm/min；溫度在25-30℃時(shí)，封孔速度約3μm/min。此時(shí)，可根據(jù)氧化膜性質(zhì)，徐州鋁合金封孔劑封閉、厚度、封孔溫度等確定封孔時(shí)間。（3）pH值對(duì)封孔質(zhì)量的影響根據(jù)pH值對(duì)封孔質(zhì)量的影響試驗(yàn)，可得pH值對(duì)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。</p><div
