style="text-indent:25px">食品加工業(yè)為應(yīng)用化學(xué)鍍鎳提供了一個(gè)巨大的潛在市場(chǎng)；之所以稱之為潛在的市場(chǎng)，是因?yàn)榛瘜W(xué)鍍鎳在食品工業(yè)的廣泛應(yīng)用中存在著障礙。比如在美國(guó)，F(xiàn)DA（美國(guó)食品和藥物管理署）對(duì)于化學(xué)鍍鎳在食品工業(yè)中的應(yīng)用尚末制訂出法規(guī)標(biāo)準(zhǔn)；通常，對(duì)于化學(xué)鍍鎳層在應(yīng)用于直接與食品接觸的情況，F(xiàn)DA采取個(gè)案處理的方式予以批準(zhǔn)。究其原因，主要是因?yàn)榻?jīng)典的化學(xué)鍍液配方中含有毒的鉛、鎘等重金屬離子作為穩(wěn)定劑的緣故。然而，許多現(xiàn)代的化學(xué)鍍鎳溶液中已經(jīng)不使用重金屬離子作穩(wěn)定劑了；顯然，這個(gè)障礙遲早將會(huì)被拆除。食品包裝機(jī)械中不與食品直接接觸的零件，如：軸承、輥筒、傳送帶、液壓系統(tǒng)和齒輪等為化學(xué)鍍鎳在食品工業(yè)中的典型應(yīng)用。湖北化學(xué)鍍鎳加工廠家學(xué)鍍鎳是一種化學(xué)溶液，在鋼部件的表面形成一層化學(xué)鍍鎳膜，有效的隔斷鋼部件與腐蝕性介質(zhì)的接觸99.</p><div

①以次磷酸鈉為還原劑時(shí)，由于有磷析出，發(fā)生磷與鎳的共沉積，所以化學(xué)鍍鎳層是磷呈彌散態(tài)的鎳磷合金鍍層，鍍層中磷的質(zhì)量分?jǐn)?shù)為1%～l5%，控制磷含量得到的鎳磷鍍層致密、無(wú)孔，耐蝕性遠(yuǎn)優(yōu)于電鍍鎳。以硼氫化物或氨基硼烷為還原劑時(shí)，化學(xué)鍍鎳層是鎳硼合金鍍層，硼的含量為1%～7%。只有以肼作還原劑得到的鍍層才是純鎳層，含鎳量可達(dá)到99．5%以上。 </p> <p> ②硬度高、耐磨性良好。電鍍鎳層的硬度*為l60～180HV，而化學(xué)鍍鎳層的硬度一般為400～700HV，經(jīng)適當(dāng)熱處理后還可進(jìn)一步提高到接近甚至超過(guò)鉻鍍層的硬度，故耐磨性良好，更難得的是化學(xué)鍍鎳層兼?zhèn)淞肆己玫哪臀g與耐磨性能。 </p> <p> ③化學(xué)穩(wěn)定性高、鍍層結(jié)合力好。在大氣中以及在其他介質(zhì)中，化學(xué)鍍鎳層的化學(xué)穩(wěn)定性高于電鍍鎳層的化學(xué)穩(wěn)定性。與通常的鋼鐵、銅等基體的結(jié)合良好，結(jié)合力不低于電鍍鎳層和基體的結(jié)合力。 </p> <p> ④由于化學(xué)鍍鎳層含磷（硼）量的不同及鍍后熱處理工藝的不同，鍍鎳層的物理化學(xué)特性，如硬度、抗蝕性能、耐磨性能、電磁性能等具有豐富多彩的變化，是其他鍍種少有的。所以，化學(xué)鍍鎳的工業(yè)應(yīng)用及工藝設(shè)計(jì)具有多樣性和**性的特點(diǎn)。 </p><p> 化學(xué)鍍鎳技術(shù)能廣為應(yīng)用的原因之一是鍍層具有優(yōu)越的耐蝕性能，它是陰極性鍍層，所以鍍層厚度及完整性是保護(hù)基材效果好壞的關(guān)鍵，否則反而加快基材的腐蝕，這點(diǎn)需充分予以重視。那么該如何提高化學(xué)鍍鎳的耐腐蝕性能呢？下面小編就為大家具體介紹一下： </p> <p> 基體質(zhì)量這是鍍層持量的基本保證，但往往被人們忽視。鍍前需了解工件材料的成分、狀態(tài)、冶金質(zhì)量及加工成型的過(guò)程，不適當(dāng)?shù)募庸?huì)造成應(yīng)力、微裂紋。工件上不應(yīng)有折疊、焊屑、毛刺、孔洞及砂眼等缺陷。鋼中的夾雜物，尤其是硫化物，不*影響鍍層的耐蝕性，還會(huì)毒化鍍液。 </p> <p> 鍍前處理基材上原有的潤(rùn)滑油或緩蝕劑是很難清洗凈的，處理不好不*會(huì)降低鍍層結(jié)合力，還會(huì)產(chǎn)生***而降低耐蝕性。除化學(xué)清洗法外，碳鋼基材常推薦使用電解清洗法，但這種清洗方法明顯地影響鍍層的耐蝕性。例如在堿性介質(zhì)中陽(yáng)極清洗會(huì)嗇鍍層孔隙率；陰極清洗雖然孔隙率低，但又可能引起氫脆。用堿性除銹劑，若換向周期性地反復(fù)清洗，即在85℃浸泡10分鐘、再陽(yáng)極清洗2分鐘，效果不如浸泡后改用陰極清洗更耐蝕。活化時(shí)鐵基體如用鹽酸活化會(huì)使腐蝕率上升，如果以稀硫酸活化效果就好一些，且時(shí)間越短越好。學(xué)鍍鎳是一種化學(xué)溶液，在鋼部件的表面形成一層化學(xué)鍍鎳膜，有效的隔斷鋼部件與腐蝕性介質(zhì)的接觸7.</p><div
