style="text-indent:25px">鉻酸是金屬表面處理劑的主要原料。常見(jiàn)金屬表面處理劑的特點(diǎn)：比較常見(jiàn)的處理劑有兩種：一種主要以除油去污為目的，其主要成分是碳酸鈉、偏硅酸納等,同時(shí)加入陰離子等活性劑或者分散劑，制作成工業(yè)用的清洗劑，使用超聲波機(jī)等機(jī)器進(jìn)行雜質(zhì)清理。而去銹使用的主要是鹽酸，同時(shí)加入一些緩蝕劑等物質(zhì)，把需要除銹的物體放置到除銹劑中，工業(yè)氧化鎳催化劑預(yù)定,實(shí)現(xiàn)去銹的目的。這種處理劑的不足主要體現(xiàn)在處理過(guò)程比較繁雜，工業(yè)氧化鎳催化劑預(yù)定，工業(yè)氧化鎳催化劑預(yù)定,需要對(duì)處理劑進(jìn)行加熱,需要耗費(fèi)大量水資源；同時(shí),清洗需要的時(shí)間也比較長(zhǎng)。金屬表面處理包括了除油、除銹、磷化、防銹等基體前處理，是為金屬涂層技術(shù)、金屬防護(hù)技術(shù)做準(zhǔn)備的。工業(yè)氧化鎳催化劑預(yù)定</p><div

style="text-indent:25px">鋁脫脂劑使用方法：1、根據(jù)待洗鋁工件油污多少將該產(chǎn)品原液與干凈水（自來(lái)水或井水）配成2%-6%的清洗溶液。2、將待洗鋁工件浸沒(méi)在已配制的清洗液中，浸漬3-5分鐘。3、將浸漬后的鋁工件從清洗溶液中撈出，用清水充分地清洗鋁工件。4、清洗溶液可以多次反復(fù)使用，由于多次使用過(guò)程中有效成分逐漸減少，應(yīng)及時(shí)補(bǔ)充適量的鋁脫脂劑原液，補(bǔ)充量為清洗溶液總量的0.1%-0.3%。產(chǎn)品特點(diǎn)：1、無(wú)毒無(wú)害，屬水基型環(huán)保清洗劑。2、除油、脫脂、脫氧化膜迅速?gòu)氐住?、清洗后的鋁工件光亮平滑，不損傷工件。4、清洗時(shí)間短，3-5分鐘即可去除油污，常溫操作，安全環(huán)保，可以節(jié)省大量的清洗時(shí)間。5、清洗成本低廉，節(jié)省人力。常用硝酸鎳溶液化學(xué)鍍鎳藥劑工藝流程：用熱的去離子水沖洗工件，使工件升溫。</p><div

style="text-indent:25px">鋁合金脫脂劑；氟離子在酸蝕脫脂液中作脫除氧化膜的加速劑，能加速溶解鋁表面的氧化膜，消除或減少擠壓模痕和其他缺陷，使鋁型材表面平整光潔、均勻一致。氟是一種體積小、電負(fù)性較強(qiáng)的鹵族元素，對(duì)鋁能起強(qiáng)烈的氧化作用，與雜質(zhì)有一定的絡(luò)合能力，能溶解鋁合金表面的錳、銅、硅等合金元素和雜質(zhì)，阻止和除去鋁材上的黑色掛灰，獲得較光亮的金屬表面。氟化氫銨的化學(xué)穩(wěn)定性強(qiáng)于氫氟酸的，對(duì)人體皮膚的傷害作用小于氫氟酸的，因此，采用氟化氫銨取代氫氟酸為溶液提供氟離子，在生產(chǎn)中使用比較安全，還可以減輕氟離子對(duì)不銹鋼設(shè)備的腐蝕。脫除氧化膜的腐蝕速度隨氟化氫銨濃度的增加而增長(zhǎng)，氟化氫銨含量不宜過(guò)高，否則反應(yīng)劇烈易造成過(guò)腐蝕，降低鋁表面光澤，不利于后續(xù)的鉻酸鹽轉(zhuǎn)化處理。</p><p
