金屬氧化處理的方法

金(jin)屬(shu)的(de)氧(yang)(yang)化(hua)(hua)處理(li)是金(jin)屬(shu)表面與(yu)氧(yang)(yang)或氧(yang)(yang)化(hua)(hua)劑作用(yong)而形成保護性的(de)氧(yang)(yang)化(hua)(hua)膜(mo)，防止金(jin)屬(shu)腐蝕。氧(yang)(yang)化(hua)(hua)方(fang)法(fa)(fa)有(you)熱(re)氧(yang)(yang)化(hua)(hua)法(fa)(fa)、堿(jian)性氧(yang)(yang)化(hua)(hua)法(fa)(fa)、酸性氧(yang)(yang)化(hua)(hua)法(fa)(fa)(黑色(se)(se)金(jin)屬(shu))以(yi)及化(hua)(hua)學氧(yang)(yang)化(hua)(hua)法(fa)(fa)、陽極氧(yang)(yang)化(hua)(hua)法(fa)(fa)(有(you)色(se)(se)金(jin)屬(shu))等。

一：酸(suan)性(xing)(xing)(xing)(xing)氧化法即(ji)將(jiang)零件置于酸(suan)性(xing)(xing)(xing)(xing)溶液中(zhong)進行處(chu)理。與堿(jian)性(xing)(xing)(xing)(xing)氧化法比較，酸(suan)性(xing)(xing)(xing)(xing)氧化法較為經濟，處(chu)理后金屬表面所生成的(de)保護膜，不銹鋼表面處(chu)理方法，耐(nai)腐蝕性(xing)(xing)(xing)(xing)和機(ji)械強度均(jun)超過堿(jian)性(xing)(xing)(xing)(xing)氧化處(chu)理后所生成薄膜的(de)性(xing)(xing)(xing)(xing)能，故(gu)應用廣泛。

表面處理簡介

工(gong)(gong)(gong)(gong)件(jian)在(zai)加(jia)工(gong)(gong)(gong)(gong)、運(yun)輸、存(cun)放等過程中，表(biao)(biao)面(mian)往往帶有氧化(hua)皮(pi)、鐵(tie)銹制模(mo)殘留的(de)型砂、焊渣、塵土以及油(you)和(he)其他污物。要(yao)涂(tu)(tu)層能(neng)牢固(gu)地附著在(zai)工(gong)(gong)(gong)(gong)件(jian)表(biao)(biao)面(mian)上，在(zai)涂(tu)(tu)裝前就必(bi)須(xu)對工(gong)(gong)(gong)(gong)件(jian)表(biao)(biao)面(mian)進(jin)行(xing)清理，不(bu)(bu)銹鋼表(biao)(biao)面(mian)處(chu)理工(gong)(gong)(gong)(gong)藝(yi)，否則，不(bu)(bu)僅影(ying)(ying)響涂(tu)(tu)層與金屬的(de)結(jie)合力和(he)抗腐蝕(shi)性(xing)能(neng)，而且還會(hui)使基體金屬在(zai)即使有涂(tu)(tu)層防護(hu)(hu)下(xia)也能(neng)繼續腐蝕(shi)，使涂(tu)(tu)層剝落，影(ying)(ying)響工(gong)(gong)(gong)(gong)件(jian)的(de)機械性(xing)能(neng)和(he)使用(yong)壽(shou)命(ming)。因此工(gong)(gong)(gong)(gong)件(jian)涂(tu)(tu)漆前的(de)表(biao)(biao)面(mian)處(chu)理是(shi)獲得質量優良的(de)防護(hu)(hu)層，不(bu)(bu)銹鋼表(biao)(biao)面(mian)處(chu)理技術，延長產品使用(yong)壽(shou)命(ming)的(de)重(zhong)要(yao)保證和(he)措施(shi)。

鋁及鋁合金表面成膜處理

1.有機物涂裝處理

  有(you)(you)機(ji)(ji)(ji)(ji)物(wu)涂(tu)(tu)裝處(chu)理(li)(li)技(ji)術包(bao)括刷(shua)涂(tu)(tu)、浸涂(tu)(tu)、噴涂(tu)(tu)和(he)電(dian)(dian)(dian)泳(yong)(yong)等，蕪(wu)湖不銹鋼(gang)表(biao)面處(chu)理(li)(li)，在建筑鋁(lv)型材的(de)有(you)(you)機(ji)(ji)(ji)(ji)聚合物(wu)涂(tu)(tu)裝中，電(dian)(dian)(dian)泳(yong)(yong)涂(tu)(tu)裝和(he)靜電(dian)(dian)(dian)噴涂(tu)(tu)為普遍(bian)(bian)和(he)可靠。有(you)(you)機(ji)(ji)(ji)(ji)物(wu)聚合物(wu)涂(tu)(tu)裝通常用化(hua)(hua)(hua)學轉(zhuan)化(hua)(hua)(hua)膜作為底層(ceng)，有(you)(you)時也有(you)(you)采用陽極氧(yang)化(hua)(hua)(hua)膜作為底層(ceng)。陽極氧(yang)化(hua)(hua)(hua)電(dian)(dian)(dian)泳(yong)(yong)復合膜起源于日本(ben)，是在鋁(lv)的(de)陽極氧(yang)化(hua)(hua)(hua)膜上，陽極電(dian)(dian)(dian)泳(yong)(yong)有(you)(you)機(ji)(ji)(ji)(ji)聚合物(wu)形成的(de)。有(you)(you)機(ji)(ji)(ji)(ji)聚合物(wu)噴涂(tu)(tu)膜處(chu)理(li)(li)在歐洲(zhou)的(de)應(ying)用比較普遍(bian)(bian)，近年來(lai)這種處(chu)理(li)(li)在我國建筑鋁(lv)型材表(biao)面處(chu)理(li)(li)方面迅速發展，幾(ji)乎已于陽極氧(yang)化(hua)(hua)(hua)處(chu)理(li)(li)平分秋色。
