YaHei";">電鍍廢氣對環境和人體健康造成巨大威脅，須妥善處理處置，從末端控制和治理角度考慮，各類廢氣污染物的控制一般從控制廢氣污染物逸出量和采取凈化治理設施兩方面采取措施。</span></p><p><span style="font-family: 微軟雅黑, "Microsoft YaHei";">在一些工藝槽溶液中投加一些表面活性劑，利用表面活性劑的發泡性，達到抑制酸霧等污染物的逸出量，也可在溶液表面加入一層塑料空心球起到阻擋酸霧逸出的作用。</span></p><p><span style="font-family: 微軟雅黑, "Microsoft YaHei";">1.酸洗霧的抑制</span></p><p><span style="font-family: 微軟雅黑, "Microsoft YaHei";">鋼鐵件的酸洗通常采用鹽酸和硫酸，銅件的酸洗多采用硝酸與硫酸的混合酸，對于酸洗產生的酸霧，在不影響操作時，可以在槽液表面加入一層塑料空心球起到阻擋酸霧逸出的作用。</span></p><p><span style="font-family: 微軟雅黑, "Microsoft YaHei";">對于加溫的硫酸槽液，由于溶液的粘度較大且溫度較高，加入少量十二烷基硫酸鈉，利用酸洗時產生的氫氣及其攪拌作用，能在溶液表面產生較厚的泡沫，從而起到較好的抑制酸霧作用。</span></p><p><span style="font-family: 微軟雅黑, "Microsoft YaHei";">室溫環境下用鹽酸退鋅、退鎘鍍層時，由于會產生較多氣泡，攪拌作用較強，因此加入少量十二烷基硫酸鈉也可起到較好的抑制酸霧作用。</span></p><p><span style="font-family: 微軟雅黑, "Microsoft YaHei";">在用混酸對銅件進行酸洗或進行工件退銅、退鎳處理時，會產生大量氮氧化合物，此時在溶液中投加少量尿素，可起到化學抑制作用。</span></p><p><span style="font-family: 微軟雅黑, "Microsoft YaHei";">2.鉻酸霧的抑制</span></p><p><span style="font-family: 微軟雅黑, "Microsoft YaHei";">鍍鉻的電流效率低，在生產過程中產生大量氫氣和氧氣。由于鍍液的表面張力大，氫氣氣泡和氧氣氣泡逸出時帶有大量能量，液面破裂時，把液膜劇烈地撕裂分散成極細的霧飛濺到大氣環境中。</span></p><p><span style="font-family: 微軟雅黑, "Microsoft YaHei";">在鍍鉻槽液加溫過程中，會有溶液蒸發，此時帶出大量鉻酸，形成鉻酸霧。鉻酸霧的抑制通常在槽液表面加一層耐鉻酸的聚乙烯或聚氯乙烯空心塑料球，起到抑制鉻霧的作用。</span></p><p><span style="font-family: 微軟雅黑, "Microsoft YaHei";">此法用于鍍硬鉻時較有效，對于頻繁進出槽的裝飾性鍍鉻效果不好。</span></p><p><br/></p></div> <div class="clear"></div> </div> </div>  <div class="clear"></div> </div>  <div class="footer clearfix"> <div class="foot_nav
