3、電鍍鎳無法對一些形狀復(fù)雜的工件進(jìn)行全表面施鍍，但化學(xué)鍍鎳過以對任何形狀工件施鍍。高磷的化學(xué)鍍鎳層為非晶態(tài)，鍍層表面沒有任何晶體間隙，而電鍍鎳層為典型的晶態(tài)鍍層。 </p> <p> 4、電鍍鎳因為有外加的電流，所以鍍速要比化學(xué)鍍鎳快得多，同等厚度的鍍層電鍍鎳要比化學(xué)鍍鎳提前完成。 </p> <p> 5、化學(xué)鍍鎳層的結(jié)合力要普遍高于電鍍鎳層。 </p> <p> 6、化學(xué)鍍鎳由于大部分使用食品級的添加劑，不使用諸如**物等有害物質(zhì)，所以化學(xué)鍍鎳比電鍍鎳要環(huán)保一些。 </p> <p> 7、化學(xué)鍍鎳目前市場上只有純鎳磷合金的一種顏色，而電鍍鎳可以實現(xiàn)很多色彩。 </p> <p> 8、化學(xué)鍍鎳技術(shù)是采用金屬鹽和還原劑，在材料表面上發(fā)生自催化反應(yīng)獲得鍍層的方法。到目前為止，化學(xué)鍍鎳是國外發(fā)展快的表面處理工藝之一，且應(yīng)用范圍也廣?；瘜W(xué)鍍鎳之所以迅速發(fā)展，是由于其優(yōu)越的工藝特點所決定。 </p> <p> <br /> </p> <p> <br /> </p><p style="text-indent:25px">中國的化學(xué)鍍鎳工業(yè)化生產(chǎn)起步較晚，但近幾年的發(fā)展十分迅速，不*有大量的論文發(fā)表，還舉行了全國性的化學(xué)鍍會議，據(jù)第五屆化學(xué)鍍年會發(fā)表文章的統(tǒng)計就已經(jīng)有300多家廠家，但這一數(shù)字在當(dāng)時應(yīng)是極為保守的。據(jù)推測國內(nèi)每年的化學(xué)鍍鎳市場總規(guī)模應(yīng)在300億元左右，并且以每年10%～15%的速度發(fā)展。⒊真正的化學(xué)鍍：從含有還原劑的溶液中沉積金屬。下面我們所提的化學(xué)

style="text-indent:25px">在食品加工過程中，會涉及鹽水、亞硝酸鹽、檸檬酸、醋酸、天然木材的煙薰，揮發(fā)性有機(jī)酸等腐蝕介質(zhì)等問題；食品加工溫度范圍為60～200，生產(chǎn)環(huán)境中相對濕度很高；在這樣的條件下，食品加工設(shè)備存在著金屬腐蝕、疲勞和磨損等問題。對于接觸食品的金屬表面，傳統(tǒng)的保護(hù)方式是電鍍硬鉻；可是，在含氯離子酸性介質(zhì)中，鍍鉻層的耐蝕年并不好；然而，化學(xué)鍍鎳在均鍍能力、高耐蝕性、防粘、脫模性等方面具有明顯的優(yōu)勢。揉面機(jī)上與食品接觸的零件采用的化學(xué)鍍鎳就是應(yīng)用成功的實例之一；其他在食品充氣裝罐機(jī)、螺桿送料機(jī)、拌料鍋、食品模具、烤盤、干燥箱，面包保溫爐等食品機(jī)械上越多地采用了化學(xué)鍍鎳?；瘜W(xué)鍍鎳合金層的耐蝕、耐磨性能。如形的散熱器、齒輪、噴油嘴、制動瓦片、減振器等等。江西紫銅化學(xué)鍍鎳加工處理</p><p

style="text-indent:25px">化學(xué)鍍中發(fā)展**快的一種。鍍液一般以硫酸鎳、乙酸鎳等為主鹽，次亞磷酸鹽、硼氫化鈉、硼烷、肼等為還原劑，再添加各種助劑。在90℃的酸性溶液或接近常溫的中性溶液、堿性溶液中進(jìn)行作業(yè)。以使用還原劑的不同分為化學(xué)鍍鎳-磷、化學(xué)鍍鎳-硼兩大類。鍍層在均勻性、耐蝕性、硬度、可焊性、磁性、裝飾性上都顯示出優(yōu)越性。化學(xué)鍍又稱為無電解鍍（Electroless plating），也可以稱為自催化電鍍（Autocatalytic plating）[1]。具體過程是指：在一定條件下，水溶液中的金屬離子被還原劑還原，并且沉淀到固態(tài)基體表面上的過程。ASTM B374（ASTM，美國材料與試驗協(xié)會）中定義為Autocatalytic plating is “deposition of a metallic coating by a controlled chemical reduction that is catalyzed by the metal or alloy being deposited”。這一過程與置換鍍不同，其鍍層是可以不斷增厚的[2]，且施鍍金屬本身也具有催化能力。安徽醫(yī)療器械化學(xué)鍍鎳</p><p
