style="text-indent:25px">達(dá)克羅膜層的保護(hù)作用：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(guò)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能。3.陰極保護(hù)作用：鋅鋁鉻涂層主要的保護(hù)作用與鍍鋅層一樣，是對(duì)基體進(jìn)行陰極保護(hù)。使用達(dá)克羅的必然性：由于電鍍不*對(duì)大氣、土地、水源造成嚴(yán)重污染，對(duì)操作工人也危害很大。國(guó)家已三令五申盡快，需要出臺(tái)新的綠色產(chǎn)業(yè)來(lái)取而代之。所以電鍍行業(yè)的下滑是必然結(jié)果，而電鍍件轉(zhuǎn)用達(dá)克羅也是必然的，達(dá)克羅生產(chǎn)過(guò)程中，沒(méi)有任何污染，是國(guó)家鼓勵(lì)發(fā)展的真正的綠色工業(yè)。</p><p style="text-indent:25px">達(dá)克羅工藝的加工很環(huán)保，不會(huì)污染環(huán)境，降低了防治污染的費(fèi)用，所以它的使用能夠幫助企業(yè)節(jié)約很多的成本。效果好。達(dá)克羅不管是在什么領(lǐng)域，是在什么零件上進(jìn)行涂覆，都能夠?qū)崿F(xiàn)良好的抗腐蝕效果，實(shí)現(xiàn)對(duì)零件的保護(hù)，非常的耐用，可以說(shuō)是一勞永逸。達(dá)克羅是DACROMET譯音和縮寫，簡(jiǎn)稱達(dá)克羅、達(dá)克銹、迪克龍.國(guó)內(nèi)命名為鋅鉻涂層，是一種新型的耐腐涂層，與傳統(tǒng)的電鍍鋅相比：鋅鉻涂層耐腐蝕性能極強(qiáng)，是鍍鋅的7—10倍，無(wú)氫脆性，特別適用于**度受力件，高耐熱性、耐熱溫度300℃，尤其適用于汽車、摩托車發(fā)動(dòng)機(jī)部件的**度構(gòu)件，高滲透性、高附著性、高減磨性、高耐氣候性、高耐化學(xué)品穩(wěn)定性、無(wú)污染性。達(dá)克羅耐熱溫度可達(dá)300℃以上。</p><div
