熱鍍鋅板的生產(chǎn)工序主要包括：原板準(zhǔn)備→鍍前處理→熱浸鍍→鍍后處理→成品檢驗(yàn)等。按照習(xí)慣往往根據(jù)鍍前處理方法的不同把熱鍍鋅工藝分為線外退火和線內(nèi)退火兩大類。</span> </p> <p> <span style="font-size:16px;">線外退火</span> </p> <p> <span style="font-size:16px;"> 就是熱軋或冷軋鋼板進(jìn)入熱鍍鋅作業(yè)線之前，首先在抽底式退火爐或罩式退火爐中進(jìn)行再結(jié)晶退火，這樣，鍍鋅線就不存在退火工序了。鋼板在熱鍍鋅之前必須保持一個(gè)無氧化物和其他臟物存在的潔凈的純鐵活性表面。這種方法是先由酸洗的方法把經(jīng)退火的表面氧化鐵皮，然后涂上一層由氯化鋅或由氯化銨和氯化鋅混合組成的溶劑進(jìn)行保護(hù)，從而防止鋼板再被氧化。屬于這個(gè)類別的熱鍍鋅方法包括：濕法熱鍍鋅法、單張鋼板法和惠林熱法。</span> </p> <p> <span style="font-size:16px;">濕法工藝</span> </p> <p> <span style="font-size:16px;"> 鋼板表面的溶劑不經(jīng)烘干（即表面還是濕的）就進(jìn)入起表面覆蓋有熔融態(tài)溶劑的鋅液進(jìn)行熱鍍鋅。此方法的缺點(diǎn)是：只能在無鉛狀態(tài)下鍍鋅，鍍層的合金層很厚且粘附性很壞。生成的鋅渣都積存在鋅液和鉛液的界面處而不能沉積鍋底（因?yàn)殇\渣的比重大于鋅液而小于鉛液），這樣鋼板因穿過鋅層污染了表面，武漢熱浸鋅。因此，武漢熱浸鋅，武漢熱浸鋅，該方法已基本被淘汰。

style="font-size:16px;">鋼板在經(jīng)過熱鍍鋅加工之后還具有良好的耐腐蝕性，特別是耐大氣腐蝕性。通過簡單的化學(xué)知識(shí)我們可以了解到，鋅的電位比鐵低，因此在電解液中，鋅層會(huì)發(fā)生溶解從而將鋼基體保護(hù)，使其不被腐蝕，從而起到了保護(hù)作用，同時(shí)，鋅層通過自身的腐蝕物也可以保護(hù)鋅層。</span>

style="font-size:16px;">1、熱鍍鋅又稱為熱浸鍍鋅,它是在高溫下把鋅錠融化,在放入一些材料,然后把金屬結(jié)構(gòu)件浸入鍍鋅槽中,使金屬構(gòu)件上附著一層鋅層。熱鍍鋅的優(yōu)點(diǎn)在于它的耐腐能力強(qiáng),鍍鋅層的附著力和硬度較好。冷鍍”即“電鍍”即把鋅鹽溶液通過電解，給鍍件上鍍層，一般不用加熱，上鋅量很少，遇到潮濕環(huán)境很容易脫落。</span><span style="font-size:16px;"></span> </p> <p> <span style="font-size:16px;">2、熱鍍鋅，針對(duì)鋼格柵板，用熱鍍鋅熱鍍鋅是化學(xué)處理，屬于電化學(xué)反應(yīng)。冷鍍鋅是物理處理，只是在表面刷一層鋅，所以鋅層易脫落。建筑施工中多采用熱鍍鋅。連續(xù)熱鍍鋅工藝，鋼材→加熱→冷卻至鍍鋅溫度→鍍鋅→冷卻冷鍍鋅就是電鍍鋅，只有1050g/m2，其本身的耐腐蝕性比熱浸鍍鋅相差很多。采用電鍍鋅的價(jià)格相對(duì)便宜一些。</span><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(jià)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(jià)鉻,從工廠排出，流入地下水源、農(nóng)田魚塘等,而六價(jià)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(jià)鉻少。</span>武漢熱浸鋅</p><p
