style="text-indent:25px">鍍鋅圓管的鋅鍍層經(jīng)鉻酸鹽鈍化之后，耐蝕性可提高6--8倍。故鍍鋅鈍化處理是必不可少的的步驟。在鈍化膜上進(jìn)行有機(jī)染色，可作低文件產(chǎn)品的防護(hù)---裝飾鍍層。為降低鋅鍍層厚又能提高耐蝕能力，國(guó)內(nèi)外采用如下兩種措施﹕一是提高鈍化膜的質(zhì)量，如用藍(lán)色，綠色，軍綠色，黑色鈍化代替常規(guī)的彩虹色鈍化膜，尤以軍綠化鈍化膜耐蝕性較好好﹔二是以較薄的含鐵0.3%--0.6%的Zn-Fe合金，或含鎳6%-10%的Zn-Ni合金代替純鋅鍍層，耐蝕性能提高三倍以上，普遍用于汽車(chē)鋼板上代替鍍鋅。昆明盤(pán)龍區(qū)6米鍍鋅圓管價(jià)格表昆明鍍鋅圓管廠(chǎng)家報(bào)價(jià)，云南贛僑貿(mào)易供應(yīng)。</p><div
