style="text-indent:25px">達(dá)克羅涂液種類繁多，但涂液的基本組成可歸納如下:1.金屬物:由鋅、鋁等物質(zhì)組成，主要為超細(xì)鱗片狀鋅、超細(xì)鱗片狀鋁。2.溶劑:為惰性有機(jī)溶劑，如乙二醇等。3.無機(jī)酸組分:如鉻酸等。4.特殊有機(jī)物:為涂液的增粘分散組份，主要成份為纖維素類白色粉末。達(dá)克羅膜層對(duì)于鋼鐵基體的保護(hù)作用可歸納為以下幾點(diǎn):1.壁壘效應(yīng):由于片狀鋅、鋁層狀重疊，阻礙了水、氧等腐達(dá)克羅產(chǎn)品蝕介質(zhì)到達(dá)基體的進(jìn)程，能起一種隔離的屏蔽作用。2.鈍化作用:在達(dá)克羅的處理過程中，鉻酸與鋅、鋁粉和基體金屬發(fā)生化學(xué)反應(yīng)，生成致密的鈍化膜，這種鈍化膜具有很好的耐腐蝕性能。3.陰極保護(hù)作用:鋅鋁鉻涂層比較主要的保護(hù)作用與鍍鋅層一樣，是對(duì)基體進(jìn)行陰極保護(hù)。宿遷材料達(dá)克羅達(dá)克羅涂層的固化溫度為300℃左右。</p><div
