低pH值有利于Al2O3與F-反應(yīng)，生成AlF63-、\、Al(OH)F53-、、Al(OH)2F43-.。其含量達(dá)到一定值時(shí)，離子間發(fā)生締合、水解和濃縮，轉(zhuǎn)化為穩(wěn)定相絡(luò)合氟化鋁Al2(OH)3F3,。在氧化膜微孔中，Al2(OH)3F3是封孔物質(zhì)；在鋁合金表面，Al2(OH)3F3是粉霜；在槽液中，Al2(OH)3F3是渾濁物。所以槽液溶鋁量太大，鋁合金易上粉，槽液易渾濁死槽。緩蝕劑的添加，正是為了保護(hù)氧化膜不上粉，降低溶鋁量，延長(zhǎng)槽液使用壽命。按實(shí)驗(yàn)結(jié)果，有機(jī)醇緩蝕劑的濃度區(qū)間為1-3g/L。（6）螯合劑濃度對(duì)封孔質(zhì)量的影響本發(fā)明螯合劑選用乙酸系(如三乙醇胺、乙二胺四乙酸等),磷酸系(如三聚磷酸鈉、焦磷酸鈉、偏磷酸鈉、氨基三甲叉磷酸（ATMP）等)和磷酸基羧酸系（如膦?；⊥槿人幔≒BTCA）等），用其強(qiáng)大的螯合鍵能，穩(wěn)定Ti4+和Al3+,確保槽液不渾濁，鋁合金不上粉。按（2）（5）式，pH升高時(shí)，容易生成Ti(OH)4和Al2(OH)3F3。這些物質(zhì)，若生成在氧化膜微孔，即為封孔物質(zhì)；若生成在鋁合金表面，即為粉；若生成在槽液中，即為渾濁物。螯合劑的加入，提高了Ti(OH)4和Al2(OH)3F3的生成門檻，徐州生產(chǎn)封孔劑價(jià)格。螯合劑的用量要特別注意，濃度太高，螯合鍵不好打開，封孔能力急劇下降。實(shí)驗(yàn)表明，徐州生產(chǎn)封孔劑價(jià)格，恰當(dāng)?shù)尿蟿舛葹?-3g/L，徐州生產(chǎn)封孔劑價(jià)格。。封孔劑不能與涂層或基體發(fā)生化學(xué)反應(yīng)
