style="text-indent:25px">達(dá)克羅涂層的基本處理方法是浸涂，實(shí)際處理時(shí)根據(jù)處理零件的大小、形狀、質(zhì)量和要求性能不同，可以采用不同的處理方法。目前工廠常用的有浸—旋轉(zhuǎn)方法、噴射方法、浸瀝法。目前，達(dá)克羅已應(yīng)用于電力、建筑、海洋工程、家用電器、小五金及標(biāo)準(zhǔn)件、鐵路、橋梁、隧道、公路護(hù)欄、石油化工、生物工程、醫(yī)療器械粉末冶金等多種行業(yè)。達(dá)克羅國(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)克羅涂層技術(shù)得到推廣，呈燎原之勢(shì)。海門達(dá)克羅生產(chǎn)廠家</p><p style="text-indent:25px">達(dá)克羅技術(shù)的基體材料范圍：鋼鐵制品及有色金屬如鋁、鎂及其合金，銅、鎳、鋅等及其合金。蘇州達(dá)克羅涂覆廠家</p><p style="text-indent:25px">達(dá)克羅則可以進(jìn)入工件的這些部位形成達(dá)克羅涂層。無(wú)污染和公害：達(dá)克羅在生產(chǎn)加工及工件涂覆的整個(gè)過程中，不會(huì)產(chǎn)生對(duì)環(huán)境有污染的廢水廢氣，不用三廢治理，降低了處理成本。工藝流程：有機(jī)溶劑除油——機(jī)械拋光——噴涂——烘烤——二次噴涂——烘烤——干燥。注意事項(xiàng)：達(dá)克羅遇光照會(huì)迅速老化，所以達(dá)克羅的涂覆過程應(yīng)該在室內(nèi)進(jìn)行。達(dá)克羅烘烤溫度過低、過高都會(huì)使達(dá)克羅喪失防腐能力，達(dá)克羅應(yīng)該在合適的溫度范圍內(nèi)烘烤。達(dá)克羅的使用周期很短，所以應(yīng)該盡快用完。蘇州達(dá)克羅涂覆廠家</p></p><br
