style="font-size:16px;">1:”鍍鉻主要是提高表面硬度，美觀，防銹。鉻鍍層具有良好的化學(xué)穩(wěn)定性，在堿、硫化物、硝酸和大多數(shù)有機(jī)酸中均不發(fā)生作用，但能溶于氫鹵酸(如鹽酸)和熱的硫酸中。因鉻不變色，使用時能長久保持其反射能力而優(yōu)于銀和鎳。工藝一般都是電鍍。 </span> </p> <p> <span style="font-size:16px;">2:鍍鎳主要是耐磨，防腐蝕，防銹，一般厚度較薄，工藝的話分電鍍和化學(xué)兩類。 </span> </p> <p> <span style="font-size:16px;">3:鍍鋅主要是美觀防銹。zn是活潑金屬，能與酸反應(yīng)，所以耐腐蝕性較差,是三種中的。</span> </p> <p> <span style="font-size:16px;">成本方面的區(qū)別鍍鉻貴,鎳其次,鋅,其中還要區(qū)分掛鍍、滾鍍等.掛鍍貴,滾鍍便宜</span> </p> <p> <span style="font-size:16px;">逼逼了那么多</span> </p> <p> <span style="font-size:16px;">還有小伙伴說</span> </p> <p> <span

style="font-size:16px;">擴(kuò)展知識：</span> </p> <p> <span style="font-size:16px;">1-電鍍生產(chǎn)主要以污水和污水中重金屬污染為主，國家已嚴(yán)厲控制電鍍行業(yè)的擴(kuò)張，并且逐年削減。</span> </p> <p> <span style="font-size:16px;">2-我國電鍍加工主要是鍍鋅、鍍銅、鍍鎳、鍍鉻，其中鍍鋅占50%，鍍銅、鉻、鎳占30%。</span> </p> <p> <span style="font-size:16px;">3-如果用途是防止生銹，則可采用鍍鋅或鍍鎘；如果重點(diǎn)是為了防止磨損，鍍鎳或鍍鉻則是選擇。</span> </p> <p> <br />

style="font-size:16px;">1 引言熱鍍鋅加工廠熱鍍鋅也稱熱浸鍍鋅，是鋼鐵構(gòu)件浸入熔融的鋅液中獲得金屬覆蓋層的一種方法。近年來隨高壓輸電、交通、通訊事業(yè)迅速發(fā)展，對鋼鐵件防護(hù)要求越來越高，熱鍍鋅需求量也不斷增加。</span> </p> <p> <span style="font-size:16px;">2 熱鍍鋅層防護(hù)性能</span> </p> <p> <span style="font-size:16px;">通常電鍍鋅層厚度5～15μm，而熱鍍鋅層一般在35μm以上，甚至高達(dá)200μm。熱鍍鋅覆蓋能力好，鍍層致密，無有機(jī)物夾雜。眾所周知，鋅的抗大氣腐蝕的機(jī)理有機(jī)械保護(hù)及電化學(xué)保護(hù)，在大氣腐蝕條件下鋅層表面有ZnO、Zn(OH)2及堿式碳酸鋅保護(hù)膜，一定程度上減緩鋅的腐蝕，這層保護(hù)膜(也稱白銹)受到破壞又會形成新的膜層。當(dāng)鋅層破壞嚴(yán)重，危及到鐵基體時，鋅對基體產(chǎn)生電化學(xué)保護(hù)，鋅的標(biāo)準(zhǔn)電位-0.76V，鐵的標(biāo)準(zhǔn)電位-0.44V，鋅與鐵形成微電池時鋅作為陽極被溶解，鐵作為陰極受到保護(hù)。顯然熱鍍鋅對基體金屬鐵的抗大氣腐蝕能力優(yōu)于電鍍鋅。</span>

<p> <span style="font-size:16px;">即是熱軋或冷軋鋼板進(jìn)入熱鍍鋅工作線之前，首要在抽底式退火爐或罩式退火爐中進(jìn)行再結(jié)晶退火，這么，鍍鋅線就不存在退火工序了。鋼板在熱鍍鋅之前必須堅(jiān)持一個無氧化物和其他臟物存在的潔凈的純鐵活性外表。這種辦法是先由酸洗的辦法把經(jīng)退火的外表氧化鐵皮鏟除，然后涂上一層由氯化鋅或由氯化銨和氯化鋅混合構(gòu)成的溶劑進(jìn)行維護(hù)，然后防止鋼板再被氧化。歸于這個類別的熱鍍鋅辦法包含：濕法熱鍍鋅法、單張鋼板法和惠林熱法。</span>

style="font-size:16px;">1彩虹色鈍化膜工藝配方及性能特點(diǎn)目前彩虹色鈍化膜常用的工藝有高鉻酸鈍化、低鉻酸鈍化、三價鉻鈍化、無鉻鈍化。1.高鉻酸鈍化高鉻酸鈍化液有重鉻酸鹽型、三酸一次鈍化型及三酸兩次鈍化型等。但重鉻酸鹽型鈍化膜光亮性差,三酸兩次鈍化型操作麻煩,周期長。因此目前使用的工藝是三酸一次鈍化型。其工藝配方口為:該配方工藝簡單,成本低,槽液穩(wěn)定,所得鈍化膜顏色均勻,結(jié)合力好,耐蝕性高,且鈍化膜具有良好的機(jī)械性能和自我修復(fù)能力。缺點(diǎn)是在生產(chǎn)過程中反應(yīng)激烈,產(chǎn)生大量飛沫,危害操作工人的身體健康.零件帶出廢液含有大量的六價鉻,從工廠排出，流入地下水源、農(nóng)田魚塘等,而六價鉻是劇毒和致物質(zhì),嚴(yán)重危害人和環(huán)境。2. 低鉻酸鈍化由于高鉻酸鈍化存在著以上不足,為了尋求一種既能降低鍍鉻廢水中鉻的含量,又能保證鈍化膜的高耐蝕性,電鍍工作者研制出了低鉻酸鈍化液。目前低鉻酸鈍化已進(jìn)人實(shí)用階段,成熟的工藝配方很多,在此列舉兩種常用的工藝配方如下:該類鈍化液所形成的膜層主要在溶液中形成，不需要在空氣中停留擱置,工藝簡單，成本低,所得鈍化膜顏色鮮艷美觀均勻,質(zhì)量好,結(jié)合力牢固,膜層致密，耐蝕性接近高鉻酸鈍化膜,槽液鉻酐含量低,零件帶出廢液含有的六價鉻少。</span>武漢熱鍍鋅</p><p
