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，江西無(wú)鎳封孔劑研究。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)，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)、厚度，江西無(wú)鎳封孔劑研究、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。封孔劑哪家質(zhì)量好，詳情可以訪問(wèn)百事德，江西無(wú)鎳封孔劑研究，相信您的選擇，值得信賴。江西無(wú)鎳封孔劑研究</p><div

本發(fā)明涉及鋁合金技術(shù)領(lǐng)域：，具體涉及一種鋁合金陽(yáng)極氧化膜封孔劑、制備方法及封閉方法。背景技術(shù)：：鋁合金具有質(zhì)量輕、耐蝕性強(qiáng)、導(dǎo)熱導(dǎo)電良好等優(yōu)點(diǎn)，在航空、航天、汽車、機(jī)械制造、民用工業(yè)中廣泛應(yīng)用。鋁合金的表面處理以陽(yáng)極氧化為主，但陽(yáng)極氧化膜層具有多孔結(jié)構(gòu)且具有較強(qiáng)的化學(xué)活性，如果不封孔或封孔質(zhì)量差，環(huán)境中的污染物會(huì)被微孔吸附并進(jìn)行深度腐蝕，**終導(dǎo)致鋁材器件使用壽命降低，也就是說(shuō)，鋁合金陽(yáng)極氧化膜的封孔質(zhì)量直接決定了鋁合金的耐蝕性，而且鋁合金陽(yáng)極氧化后一般需要染色處理以得到具有良好外觀效果的外觀件，若不能保證封孔質(zhì)量，也會(huì)嚴(yán)重影響鋁合金的外觀形效果。目前，國(guó)內(nèi)外通常使用以ni2+及f-為基本成分的ni-f封孔劑，但ni-f封孔體系消耗的鎳及氟太多且又傷害人體的健康；現(xiàn)有的無(wú)鎳封孔劑又較難滿足生產(chǎn)上的品質(zhì)要求，無(wú)法大規(guī)模應(yīng)用。技術(shù)實(shí)現(xiàn)要素：本發(fā)明主要針對(duì)上述現(xiàn)有技術(shù)存在的問(wèn)題，提供一種鋁合金陽(yáng)極氧化膜封孔劑，該封孔劑不含鎳，且能夠得到封孔質(zhì)量以及耐蝕性均較好的產(chǎn)品。本發(fā)明方面，提供一種鋁合金陽(yáng)極氧化膜封孔劑，該封孔劑包括：鉬酸鹽、磷酸鹽、碘的化合物、鑭的化合物、硅烷偶聯(lián)劑和水。本發(fā)明第二方面。</p><p> 本發(fā)明還提供一種上述方法制備得到的載硒的介孔二氧化硅納米材料。本發(fā)明還提供一種上述方法制備得到的載硒的介孔二氧化硅納米材料的應(yīng)用。本發(fā)明采用溶膠-凝膠方法制備得到介孔二氧化硅(msns)，并進(jìn)一步利用化學(xué)刻蝕法處理獲得一種較大孔徑的介孔二氧化硅，然后通過(guò)超聲輔助-熔融滲透方法(ultrasonicationassisted-meltinfiltration，ua-mi)負(fù)載高量納米硒(se)，超聲條件下將抗壞血酸溶液迅速滴加入硒源和擴(kuò)孔的介孔二氧化硅溶液中反應(yīng)，得到混合溶液，然后將混合溶液冷凍干燥，煅燒，這樣可以使納米se充分填充在孔道內(nèi)，從而負(fù)載高量納米硒，由于納米se充分填充在孔道內(nèi)，可達(dá)到緩慢持久的釋放效果。本發(fā)明制備的擴(kuò)孔的msns平均孔徑和孔容分別為，將其作為載體負(fù)載納米硒se得到的se-msns，其中含硒量比較高可達(dá)45wt.％，且負(fù)載量在5wt.％-45wt.％可精確調(diào)控，粒徑為119±4nm。本發(fā)明中se-msns功能單元結(jié)構(gòu)穩(wěn)定、尺寸可控、具有良好的分散性，更重要的是可以利用更少量的msns負(fù)載更多量的se，提高了納米se的負(fù)載率和msns的利用率。有益效果本發(fā)明獲得的se-msns具有載硒量高、可調(diào)控性強(qiáng)，分散性好，顆粒均一，se可以充分填充在msns的孔道中。相較于純se。封孔劑有足夠的滲透性因?yàn)榭紫稄澢旨?xì)小，沒有足夠高的滲透性，難以充填到必需程度。</p><div

日常生活中接觸到的各種鋁合金外殼，表面含鎳，對(duì)人體造成的持續(xù)傷害，已日益引起社會(huì)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(yīng)鋁合金日益深入人類日常生活各方面的大趨勢(shì)。但如何用好氟鈦酸，技術(shù)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(yīng)，釋放出OH-，使槽液pH升高。F-是促進(jìn)封孔物質(zhì)氫氧化鈦和氟鋁絡(luò)合物Al2(OH)3F3形成的關(guān)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(gè)致命難題：（1）從分子式看，氟鈦酸與氟化鎳相比，氟太高，易結(jié)粉霜;（2）氟鈦酸pH工作點(diǎn)太低，當(dāng)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(shí)現(xiàn)無(wú)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。江西無(wú)鎳封孔劑研究</p><p
