style="text-indent:25px">鋁是一種比較活躍的金屬，因此，在空氣中會自發(fā)形成非常薄的氧化膜，在大氣中，耐蝕性高。由于，該層氧化膜的厚度比較薄，厚度只有約4納米，而且，氧化膜結構松散、多孔、硬度低、耐磨性差、機械強度低。因此，為了達到保護目的，必須鋁件鈍化處理，在其表面生成一層鈍化膜，來提高鋁合金的耐腐蝕性。鋁具有密度小、強度大、耐蝕性好、導電性和導熱性高、可焊接、塑性好、易加工、優(yōu)異的表面裝飾性能等優(yōu)點。在工業(yè)生產(chǎn)中，純鋁一般會加入一些合金元素，北京數(shù)碼配件鋁鈍化表面處理，制成各種鋁合金，如硬鋁、超硬鋁，北京數(shù)碼配件鋁鈍化表面處理、防銹鋁、鑄鋁等。鋁合金的物理力學性能優(yōu)于純鋁，因此，普遍應用于飛機，北京數(shù)碼配件鋁鈍化表面處理、汽車、火車、船舶等制造工業(yè)。在通常情況下，鈍化處理就是用鈍化劑的化學作用在金屬表面形成一層致密氧化膜。北京數(shù)碼配件鋁鈍化表面處理</p><div

style="text-indent:25px">由于鋁和鋁合金底材表面的附著力較差，因此必須要經(jīng)過表面預處理：如鋁鈍化處理，電鍍處理，陽極氧化處理等等，使其表面形成一層鈍化轉化膜。清洗后的鈍化處理不僅能增強涂膜的結合力，而且能使耐腐蝕性能也提高。鋁及鋁合金鈍化處理工藝一般為：除油脫脂清洗→清水洗→鋁化學拋光去氧化皮→清水洗→鋁鈍化處理→清水洗→浸泡純凈水→干燥。鋁及鋁合金鈍化處理工藝操作流程說明如下：除油脫脂清洗：目的主要是去除鋁合金表面沾附的油污和臟污等雜質。用鋁材清洗劑，環(huán)保配方，不腐蝕鋁件，清洗鋁件表面不變色，可采用浸泡洗、噴洗和超聲波清洗。除油去污快，通常只需要浸泡1-3分鐘即可徹底清洗干凈。河北鋁合金皮膜代加工廠家鋁合金處理后產(chǎn)生的鈍化膜，具有很好的穩(wěn)定性和耐蝕性。</p><div

style="text-indent:25px">鋁合金鈍化，當中有道十分重要的工序，那就是活化，大多數(shù)人不明白，鋁合金放入鈍化液之前，為什么要進行活化？活化的作用是什么？活化有很多的作用，工業(yè)生產(chǎn)中，經(jīng)常使用稀硝酸，或者使用稀硝酸加適量的氟化氫銨對鋁合金進行活化，活化的優(yōu)點和作用有下面這幾條：先，活化劑會對鋁合金的表面進行輕微的酸蝕，去除鋁合金表面的輕微氧化膜，使鋁合金露出良好的鋁合金的本體，有利于鋁合金鈍化層的形成；再是，能夠消除鋁合金表面殘留的物質和表面的一些雜質，消除雜質對成膜質量帶來的不利因素，能讓鋁合金鈍化液與金屬更好的接觸，提高鈍化形成的速度和質量；然后，能更快速、更均勻的的形成成膜結晶，防止大晶體的成長，使鈍化膜的細而致密，形成好的鈍化膜層；然后，縮短鈍化成膜時間，縮短了鈍化化處理的時間。之后，有利于鋁合金提高鈍化后的耐腐蝕性能提高。因此，可以看到，活化在鋁合金鈍化過程中的作用相當重要。鋁合金鈍化處理工藝，操作也非常簡單，人人都可以掌握。</p><div
