如醋酸、氨水、氟離子、乙二胺四乙酸、有機磷酸鹽等。鎳離子一旦與這些絡合劑絡合之后，十分穩(wěn)定，無法通過絮凝沉淀或者離子交換的方法將其去除，因此呈溶解性的絡合態(tài)銀極易引起廢水超標。[0010]中國**CN公開了一種采用酸化法破絡合技術對電鍍鎳廢水進行前處理，在強酸條件下，常用的絡合如檸檬酸，蘇州鋁材表面封孔劑廠家、氨水、草酸等失去或減弱與鎳離子絡合能力，從而可使絡合態(tài)的金屬鎳游離出來，該方法能使部分較弱的絡合劑釋放出鎳離子，但是該方法存在的不足是:其無法釋放有機磷酸鹽類絡合劑如乙二胺四甲叉磷酸鈉所絡合的鎳。此外加酸之后，在后續(xù)的樹脂吸咐鎳離子的工藝環(huán)節(jié)會降低該樹脂對鎳的吸附容量及性能。[0011]中國**CN提出采用芬頓氧化技術使鎳的絡合物破除形成自由鎳的方法。該方法依據(jù)由芬頓氧化產(chǎn)的羥基自由基與二價鐵離子具有一定的氧化還原能力，蘇州鋁材表面封孔劑廠家，對絡合物進行降解，從而破除絡合形態(tài)的鎳形成游離態(tài)鎳。芬頓氧化雖能有效地氧化降解水體中有機污染物，然而對Ni-EDTA絡合的降解釋放效率較低，蘇州鋁材表面封孔劑廠家。因此，該方法只能破除絡合能力較弱的那部分鎳的絡合物，對于絡合能力較強的鎳絡合物破除效果不明顯，無法達到持續(xù)穩(wěn)定的除鎳效果，同樣，該方法也易導致鎳排放超標。封孔劑選哪家，百事德為您服務！相信您的選擇，值得信賴。蘇州鋁材表面封孔劑廠家</p><div

在以氟鈦酸為封孔主要成分的無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，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，新配方對水質要求不高，開槽用自來水即可，所含Ca2+、Mg2+可被螯合劑完全屏蔽。氟化鎳封孔的F-濃度為，分子結構中F-不夠，需要額外補氟；氟鈦酸分子結構中，氟含量過高，為此，配方中專門設置緩蝕劑，降低氟的腐蝕能力，故F-按式（2），自動水解平衡，無需檢測和控制。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）顯示封孔動力學的全過程。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，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-進一步水解，生成封孔物資Ti(OH)4，完成封孔。由此可見。鋁材封孔劑分析封孔劑哪家好，詳情可以訪問百事德！</p><div

7）雜質離子對封孔質量的影響在生產(chǎn)過程中不斷帶進雜質離子，造成雜質的積累，如NH4+、Na+、K+、Ca2+、Mg2+等陽離子增多，螯合劑消耗加快。因此，把好清洗關至關重要。另外，槽液pH過低時，可用氨水調節(jié)pH值至，不要用氫氧化鈉來調節(jié)，這樣可有效阻止Na+消耗螯合劑。影響鋁合金無鎳封孔質量的因素很多，主要有氟鈦酸濃度、緩蝕劑濃度和螯合劑濃度，這三個因素是決定鋁合金封孔質量的關鍵；槽液的pH值、溫度和封孔時間是影響鋁合金封孔質量的重要因素；而提高槽液的潔凈度、減小雜質的含量是鋁合金封孔質量的重要保證。試驗表明，鋁合金無鎳封孔劑的生產(chǎn)工藝條件應為：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℃，時間5-15min，PH值。氟鈦酸體系無鎳封孔新技術有以下創(chuàng)新點：1、采用氟鈦酸作為封孔劑的主要成分，建立了無鎳封孔新藥劑配方及工藝，從源頭徹底消除了鎳鹽對水質的污染；2、采用螯合技術，解決了封孔液分解沉淀問題；3、采用緩蝕技術，降低溶鋁量，減少表面上粉，延長槽液壽命；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>

日常生活中接觸到的各種鋁合金外殼，表面含鎳，對人體造成的持續(xù)傷害，已日益引起社會的高度重視。采用氟鈦酸封孔，其封孔成分為氫氧化鈦，徹底，正好適應鋁合金日益深入人類日常生活各方面的大趨勢。但如何用好氟鈦酸，技術難度非常大。按（3）式，pH升高，氟鈦酸分解出氫氧化鈦，正好是所需要的封孔成分。按（2）式，氟鈦酸水解，電離出F-；按（4）式，F(xiàn)-與氧化膜反應，釋放出OH-，使槽液pH升高。F-是促進封孔物質氫氧化鈦和氟鋁絡合物Al2(OH)3F3形成的關鍵離子。如上所述，氟鈦酸有鈦有氟，完全可作為封孔劑的主要成分，且封孔速度快，封孔溫度低。但研發(fā)中遇到以下幾個致命難題：（1）從分子式看，氟鈦酸與氟化鎳相比，氟太高，易結粉霜;（2）氟鈦酸pH工作點太低，當pH值大于，槽液分解，形成氫氧化鈦沉淀，封孔優(yōu)化區(qū)間只能在3-4之間；（3）氟高，pH值低，鋁合金表面氧化膜易被腐蝕；（4）氟高，pH值低，溶鋁量太大，槽液易渾濁，鋁合金易上粉。只有解決高氟、低pH值下氧化膜被腐蝕、鋁合金上粉、槽液渾濁的難題，才能有效使用氟鈦酸，實現(xiàn)無鎳封孔。為此，選用緩蝕劑和螯合劑，與氟鈦酸配伍，解決高氟、低pH值下鋁合金上粉和槽液渾濁難題。緩蝕劑。蘇州鋁材表面封孔劑廠家</p><p
