style="text-indent:25px">達克羅的涂層經(jīng)過高溫烘烤后，在工件的表面形成了由鋅、鋁片及復(fù)合鹽組成的涂層，它與鋼鐵基體有著良好的結(jié)合力，所以它的附著性相當(dāng)?shù)暮?。同時，這樣形成的涂層表面，有利于各種涂料的再涂裝。達克羅優(yōu)點解析達克羅涂覆生產(chǎn)過程中，工件在前處理時，*生成少量的鐵銹和粘附在工件表面的油污，整個生產(chǎn)是在一個封閉循環(huán)的工序中進行，達克羅涂液在固化時向外排放的主要是涂液中的水份，因此對外界無污染。極強的抗腐蝕性能達克羅涂層在厚度一般情況下，一涂的厚度3～5μm，二涂二烘在6～10μm，根據(jù)統(tǒng)計，在標準鹽霧試驗下，達克羅涂層每100h消耗1μm，而電鍍鋅時涂層每10h即消耗1μm，因此達克羅涂層的抗鹽霧侵蝕能力，在同等涂層厚度下，是電鍍抗腐能力的7～10倍。做的好的達克羅的涂層，耐鹽霧侵蝕能力可達1000h以上。啟東達克羅表面處理報價在裝備上推廣達克羅涂層取代鋅鍍層，比較它們的性能指標是必要的。</p><div

style="text-indent:25px">達克羅涂層的鉻酸聚合物中沒有結(jié)晶水，且鋁\鋅片的熔點較高，所以涂層高溫耐蝕性極好。對于達克羅的生產(chǎn)工藝，我們必須熟悉，現(xiàn)在有專門的涂料清洗設(shè)備對達克羅的加工，這項技術(shù)已經(jīng)在我們的生活中發(fā)揮了重要的作用。在達克羅加工過程中，達克羅涂料使用相關(guān)檢測方法分析。首先，從達克羅涂層的粘合強度試驗來看，工業(yè)上主要使用膠帶試驗方法來完成鋅-鉻涂層與基材的粘合強度。要求在試驗后涂層不應(yīng)剝離或從基材上露出，但要使膠帶變色并粘附在鋅和鋁顆粒上。耐水性試驗是將樣品浸入40℃的去離子水中，連續(xù)浸泡240小時，取出樣品并在室溫下干燥，然后進行粘合強度試驗。試驗結(jié)果應(yīng)符合粘合強度試驗的要求。</p><p style="text-indent:25px">達克羅涂液，就液體而言，A液部分主要有表面活性劑和鋅鋁粉組成，這個部分在生產(chǎn)過種中，主要是混合的過程，鋅粉很輕，如果做不好會很揚塵，不知道你能不能接觸到這個部分。還有就是表面活性劑，主要是烷基酚聚氧乙烯醚類的。這種東西在歐盟的ROHS標準中是禁用的，它主要是可以使雄性魚雌性化，對人類的影響不詳。達克羅含有對環(huán)境有害的鉻離子尤其是六價鉻離子，但是工人如果在使用的過程中注意防護就不會有什么意外。但是達克羅燒結(jié)溫度高需要的固化時間長，當(dāng)然也需要更多的能耗。達克羅涂液溶劑：為惰性有機溶劑，如乙二醇等。</p><div

style="text-indent:25px">達克羅的應(yīng)用范圍很廣，它不但可以處理鋼、鐵、鋁及其合金，還可以處理燒結(jié)金屬，以及特殊的表面處理，但是達克羅也有兩個局限性。達克羅涂層的導(dǎo)電性能不是太好，因此不宜用于導(dǎo)電連接的零件。達克羅涂層的表面硬度和抗劃傷能力略差，特殊場合使用需要進行后處理。達克羅是新型的防腐涂料，國內(nèi)命名為鋅鉻涂層，達克羅早在二十世紀五十年代末就誕生了。在北美、北歐寒冷的冬天，人們用鹽來緩解路面冰凍嚴重的問題，但后果是損壞了鋼鐵的基體，導(dǎo)致交通工具嚴重受損，一下子陷入了難題。研制了以金屬鋅片為主同時加入鋁片、鉻酸、去離子水做溶劑的高分散水溶性涂料，這就是先的達克羅的基本雛形，彌補了傳統(tǒng)工藝防腐壽命短的缺陷。后來，達克羅技術(shù)被美國軍方采納，成為一項防腐技術(shù)。國外已明確建議汽車上≥10.9級的緊固件要使用達克羅涂層防腐。達克羅涂料又稱:鋅基鉻鹽涂料，達克銹、高克銹涂料等名稱。深圳金屬表面達克羅處理</p><p style="text-indent:25px">達克羅不*要考慮結(jié)構(gòu)設(shè)計和制造工藝，還要注意到裝配的工藝性，甚至環(huán)保及經(jīng)濟性的要求。鎮(zhèn)江達克羅表面處理廠家</p><p style="text-indent:25px">達克羅技術(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。而且涂覆全過程中無污染，在金屬表面處理歷史上是一場**，是當(dāng)今世界上金屬表面處理富有表示性的高新技術(shù)。達克羅涂液的組份及包裝：X組份：由鋅片、鋁片及乙二醇等組成，呈銀灰色至銀白色金屬漿體；Y組份：由鉻酸鹽、助劑及去離子水構(gòu)成的橙紅色的液體；C組份：羥乙基纖維素類增粘劑，白色至微黃色粉末；包裝狀況：X劑8.3kg鍍鋅鐵桶包裝，Y劑25kg塑料桶，C劑小鐵桶包裝。配比：X劑：Y劑=1：1.4配液的設(shè)備加熱或冷卻的水浴裝置：目的調(diào)整X、Y劑起始溫度25℃左右，控制反應(yīng)溫度在35℃左右。鎮(zhèn)江達克羅表面處理廠家</p></p><br
