是銀(Ⅰ)化合物的溶液被還原為金屬銀的化學(xué)反應(yīng)，由于生成的金屬銀附著在容器內(nèi)壁上，光亮如鏡，故稱為銀鏡反應(yīng)。2.原理：反應(yīng)方程式： CH3CHO+2Ag(NH3)2OH→（水浴△）CH3COONH4+2Ag↓+3NH3+H2O 化合態(tài)銀被還原，乙醛被氧化。備注：原理是銀氨溶液的弱氧化性。本試驗(yàn)可以使用其他有還原性的物質(zhì)代替乙醛，例如葡萄糖（與乙醛相似，也有醛基）等。甲醛（可看作有兩個(gè)醛基）的話被氧化成碳酸銨（NH4）2CO3。 C6H12O6+2Ag(NH3)2OH----→（水浴加熱）C5H11O5COONH4+3NH3↑+2Ag↓+H2O 葡萄糖的反應(yīng)方程式若要體現(xiàn)出葡萄糖內(nèi)部的結(jié)構(gòu)以及斷鍵情況： CH2OH-CHOH-CHOH-CHOH-CHOH-CHO+2Ag(NH3)2OH→(水浴加熱） CH2OH-CHOH-CHOH-CHOH-CHOH-COONH4+2Ag↓+3NH3↑+H2O

style="text-indent:25px">對(duì)當(dāng)前我國(guó)電鍍鋅鎳合金現(xiàn)狀的一些看法，我國(guó)對(duì)于鋅鎳合金的研究始于上世紀(jì)八十年代，其所研究的皆是酸性氯化物電鍍工藝。在此項(xiàng)研究中成功地解決酸性氯化物電鍍鋅鎳合金的技術(shù)關(guān)鍵－找到并確定有效的制止低陰極電流密度區(qū)鎳沉積的較佳組合添加劑。由于這一突破，該項(xiàng)工藝可以用于形狀較為復(fù)雜鋼鐵件的掛鍍，也可用于滾鍍。自一九九三年起先后多家單位用此工藝投入工業(yè)批量生產(chǎn)，其中一項(xiàng)主要加工產(chǎn)品就是電纜橋架，在近十年里其加工量達(dá)到1–2萬(wàn)噸。</p><p

style="text-indent:25px">汽車零件鋅鎳合金電鍍工藝添加劑：1.氫氧化鈉。氫氧化鈉主要起絡(luò)合作用,過(guò)量的氫氧化鈉是穩(wěn)定電鍍液的必要條件。氫氧化鈉為強(qiáng)電解質(zhì),有利于降低鍍液內(nèi)阻,減少電能的消耗和防止鍍液溫升過(guò)快,同時(shí)有利于陽(yáng)極溶解。若氫氧化鈉含量過(guò)高,則會(huì)引起陽(yáng)極溶解過(guò)快,使鍍液中鋅含量自然升高,溶液比例失調(diào),造成故障。2.絡(luò)合劑。眾所周知,鎳離子在一般的堿性溶液中形成氫氧化鎳沉淀,無(wú)法參與電鍍反應(yīng),絡(luò)合劑的加入使溶液穩(wěn)定。絡(luò)合劑BASE是多元胺化合物,也是環(huán)氧氯丙烷系列的多聚型表面活性物。其分子中含有—OH、—N、—CH等多個(gè)極性基團(tuán),致使能定向地在陰極表面上產(chǎn)生特殊的吸附。它又是一種季胺鹽,帶正電荷,使吸附變得容易進(jìn)行,絡(luò)合劑BASE不僅可以使兩種金屬的電極電位接近,而且還可以使電流密度范圍加寬,對(duì)雜質(zhì)敏感性降低,鍍層塑性增加、鍍層結(jié)晶細(xì)致,分散能力和深鍍能力提高。添加劑過(guò)量,將會(huì)造成鍍層脆性增大;添加劑含量過(guò)低,則會(huì)降低鍍液的電流效率。浙江鎳鋅哪個(gè)電鍍廠家質(zhì)量好</p><p
