style="text-indent:25px">電鍍鋅鎳合金的技術(shù)指標:1.鍍層鎳含量：鍍層耐蝕性與其鎳含量有著密切的關(guān)系。實驗及有關(guān)資料均證明，鎳含量為13%左右的鋅鎳合金鍍層耐蝕性很好。因此，通常鋅鎳合金鎳含量控制在8～16%范圍內(nèi)，可滿足耐蝕性的要求。2.鍍層厚度：通常鍍層厚度在5～15μm即可滿足耐蝕性要求。對無公差要求的構(gòu)件，如護欄等，厚度可達20μm以上。3.鈍化膜質(zhì)量：鋅鎳合金經(jīng)鈍化處理后耐蝕性得到了提高。鈍化膜分為白色、黑色和五彩色三種，其耐蝕性順序為：白色鈍化<黑色鈍化<五彩鈍化。4.鍍層結(jié)合力：根據(jù)GB5270多種方法檢測合格。5.耐蝕性：鎳含量為13%左右的鍍層經(jīng)五彩鈍化后，耐中性鹽霧實驗2500小時以上不出現(xiàn)紅銹，預計耐大氣腐蝕15年以上。南京合金鍍鎳有哪些電鍍鋅鎳合金的技術(shù)指標:通常鋅鎳合金鎳含量控制在8～16%范圍內(nèi)，可滿足耐蝕性的要求。</p><div

style="text-indent:25px">電鍍鋅鎳合金是取代鍍鋅工藝的較佳選擇,其獨到之處,不僅鍍層防護性能遠遠超過普通鍍鋅,而且氯化物鍍鋅溶液可以直接轉(zhuǎn)化為氯化物鋅鐵合金溶液。上這種新工藝很容易,只需將原溶液進行大處理,基本去除原有光亮劑,加入鐵鹽和新的光亮劑就成為新工藝了,這種調(diào)整改變基本不增加投資。通過氯化鉀鍍鋅與鋅鐵合金的生產(chǎn)比較,我們有如下體會:鋅鐵合金鍍層比鉀鹽鍍鋅層結(jié)晶更細小致密,防護性能更優(yōu)異。鉀鹽鍍鋅溶液分散能力不如鋅鐵合金溶液好,80ｄｍ2的工件,鉀鹽鍍鋅時,平面件中間部位呈蛋形發(fā)霧不亮。轉(zhuǎn)化為鋅鐵合金鍍液后這種現(xiàn)象消除,整個色澤光亮一致。鉀鹽鍍鋅低鉻彩鈍易脫膜,白鈍易變色,轉(zhuǎn)化為鋅鐵合金鍍液后,這種現(xiàn)象未出現(xiàn)過。鉀鹽鍍鋅特別是滾鍍液每月需大處理一次,否則不能正常生產(chǎn),轉(zhuǎn)化為鋅鐵合金鍍液后一年不處理照常生產(chǎn)。鍍鋅鐵合金的綜合成本低于鉀鹽鍍鋅,有較好的經(jīng)濟效益。</p><p style="text-indent:25px">電鍍鎳中小孔的故障是一個相當復雜的問題，因獨特條件或溶液成分分歧標準而產(chǎn)生小孔，則解救尚易，只需改改獨霸條件或調(diào)劑溶液成分使之合適請求便可能解決。如因溶液有雜質(zhì)(金屬雜質(zhì)或有機雜質(zhì))的傳染而產(chǎn)生小孔，則必須找出其根源，隔靴搔癢，才干獲得解決。在沒有雜質(zhì)的景象下，一個簡略而有用的編制為插手防小孔劑，在光澤性鍍鎳中可插手潤濕劑如十二烷基硫酸鈉，用量為0.01～0.05克/升。在通俗鍍鎳中，可在天天工作終了往后插手雙氧水0.1毫升/升。插手后將溶液予以完整攪拌。在雙氧水(或其它氧化劑)的存不才，藍本H+在陰極還原成H2的反響由氧化劑在陰極上的還原而庖代之，使氫氣泡無以產(chǎn)生，小孔亦可防止。但鍍液內(nèi)如含有過量的雜質(zhì)，則這些編制的下場亦遭到影響，甚至無效，這時辰就應對鍍液進行凈化措置。)鍍件的向下面鍍層有小孔，這常常是有機雜質(zhì)吸附、同化在鍍層概況，使此部位憎水，氣體易勾留此部位而產(chǎn)生。鍍件向上面鍍層小孔，這凡是是密度較大的非導體懸浮物沉降在該處，使鍍層粗糙而釀成的。電鍍鋅鎳合金具有優(yōu)異的耐腐蝕性。</p><div

style="text-indent:25px">鍍層性能指標是電鍍工藝所保證的鍍層性能與質(zhì)量的指標，是直觀地評價電鍍工藝水平的重要指標，比如鍍層的光亮程度、裝飾性能、鍍層脆性、抗腐蝕性能、鍍層孔隙率等。功能性鍍層便要加上功能性能指標，比如反射光系數(shù)、電導率、可焊性、耐磨性等。電鍍鋅鎳合金的這兩類指標都屬于水平比較高的先進工藝，有的時候鍍液性能指標好的工藝，不一定會有好的鍍層指標；而有些鍍層指標好的工藝，鍍液指標卻不好。人們通常以鍍層指標為主用來判斷與選擇電鍍工藝，也就是說為獲得好的鍍層有時候不得不采用鍍液性能比較差一些的鍍種。電鍍鋅鎳合金應用范圍：可經(jīng)常應用于汽車工業(yè)、緊固件工業(yè)、電纜橋架等。南通鎳鋅表面處理找哪家</p><p style="text-indent:25px">采用酸性鋅鎳合金電鍍工藝其生產(chǎn)成本可降低50%左右。南通鎳鋅表面處理找哪家</p><p style="text-indent:25px">電鍍鋅鎳合金工藝目前存在的問題是弱酸性氯化鉀鍍鋅鎳合金，光亮劑中應用了大量的表面活性劑，這給廢水處理帶來了很大的問題和困難，對環(huán)境污染影響比較大，同時對設(shè)備的腐蝕性也很大。電鍍鋅鎳合金的弱酸性硫酸鹽鍍鋅鎳合金，整平性能差、分散和覆蓋的能力差，防腐蝕性也比較差，比較適合簡單的要求不高的一般工件。電鍍鋅鎳合金的堿性鋅酸鹽鍍鋅鎳合金，電流效率很低，隨著鍍液使用時間的不斷增加，碳酸鈉的持續(xù)積累，雖然有冷凍設(shè)備去除碳酸鈉的作用，但是電流效率仍會不斷的下降，電流效率會低于一半以下，但無法處理，很多電鍍鋅鎳合金廠家不得不更換鍍液，無形中增加了生產(chǎn)的成本，這就需要廣大的電鍍工作人員不斷尋找更有效的配位劑與添加劑，改進電鍍的工藝，解決這個難題。南通鎳鋅表面處理找哪家</p><p
