style="text-indent:25px">化學(xué)鍍鎳的分類：按鍍液的PH值分類有酸性、中性和堿性三類。按沉積溫度分類有低溫、中溫、高溫三類。按合金成分分類有低磷、中磷和高磷三類。按所用還原劑分類有Ni-P、Ni-B等。化學(xué)鍍鎳廢液中，若不存在絡(luò)合劑或絡(luò)合劑的量較少時(shí)，可直接采用氫氧化鈉（濃度為6mol/L）調(diào)節(jié)pH值，根據(jù)廢液中鎳離子的濃度，加入適量的NaOH，使鎳離子沉淀為Ni(OH)2除去。為提高鍍層的質(zhì)量、鍍液的穩(wěn)定性及金屬鎳的沉積速度，化學(xué)鍍鎳液中都添加各種絡(luò)合劑。若廢液中含有蘋果酸、酒石酸和檸檬酸等絡(luò)合劑時(shí)，可使用CaO調(diào)節(jié)廢液的pH值，使這些有機(jī)酸生成相應(yīng)的鈣鹽沉淀除去，由于蘋果酸鈣的溶解度比較大。</p><p style="text-indent:25px">用次磷酸鹽作還原劑的化學(xué)鍍鎳溶液中鍍得的鍍層含有4%～15%的磷，是一種鎳磷合金，以硼氫化物或胺基硼烷作還原劑得到的鍍層才是純鎳層，含鎳量可達(dá)99.5%以上。剛沉積出來的化學(xué)鍍鎳層是無定型的，呈非晶型薄片狀結(jié)構(gòu)物質(zhì)。鍍層中磷含量主要決定于溶液的pH值，隨著pH值降低，磷含量增大。常規(guī)的酸性化學(xué)鍍鎳溶液中沉積出的鍍層含磷量為7%～12%，而堿性溶液中沉積的鎳層含磷量為4%～7%。此外，溶液的組成及各組分的含量和它們的相對(duì)比率，以及溶液的工作溫度等都對(duì)含磷量有一定的影響?；瘜W(xué)鍍鎳經(jīng)過多年的不斷探索與研究，近幾年已發(fā)展極成熟。</p><div

style="text-indent:25px">化學(xué)鍍鎳與電鍍相比有如下優(yōu)點(diǎn)：不需要外加直流電源設(shè)備。鍍層致密，孔隙少。不存在電力線分布不均勻的影響，對(duì)幾何形狀復(fù)雜的鍍件，也能獲得厚度均勻的鍍層;可在金屬、非金屬、半導(dǎo)體等各種不同基材上鍍覆?；瘜W(xué)鍍鎳工藝在電子工業(yè)中有重要的地位。由于采用的還原劑種類不同，使化學(xué)鍍所得的鍍層性能有明顯的差異，因此，在選定鍍液配方時(shí)，要慎重考慮鍍液的經(jīng)濟(jì)性及所得鍍層的特性。目前，化學(xué)鍍鎳、銅、銀、金、鈷、鈀、鉑、錫以及化學(xué)鍍合金和化學(xué)復(fù)合鍍層，在工業(yè)生產(chǎn)中已被采用?；瘜W(xué)鍍鎳廢液的pH值在7左右時(shí)，亞磷酸鈣的溶解度將急劇下降。慈溪化學(xué)鍍鎳液檢測(cè)</p><p
