億佰淺談電泳涂裝

電(dian)(dian)泳(yong)涂(tu)裝(zhuang)是(shi)將具有導電(dian)(dian)性的(de)(de)(de)被(bei)涂(tu)物浸漬在(zai)裝(zhuang)滿水(shui)的(de)(de)(de)、濃度(du)比較低的(de)(de)(de)電(dian)(dian)泳(yong)涂(tu)料槽中(zhong)作(zuo)為陽(yang)極(ji)（或陰極(ji)），在(zai)槽中(zhong)另外設置與其(qi)相對應的(de)(de)(de)陰極(ji)（或陽(yang)極(ji)），在(zai)兩極(ji)間通一(yi)定時間的(de)(de)(de)直流電(dian)(dian)，在(zai)被(bei)涂(tu)物上析出不(bu)溶于水(shui)的(de)(de)(de)、均一(yi)的(de)(de)(de)涂(tu)膜的(de)(de)(de)一(yi)種涂(tu)裝(zhuang)方法。

陽離子水性(xing)涂(tu)(tu)(tu)料在(zai)外加電場的作用下，涂(tu)(tu)(tu)裝(zhuang)電泳線價(jia)位，通過電氣泳動(dong)，產生(sheng)電泳、電解、電沉積和電滲反應，從而將涂(tu)(tu)(tu)料顆粒涂(tu)(tu)(tu)覆在(zai)陰極工件表面，形成防腐(fu)、裝(zhuang)飾(shi)和功能性(xing)的涂(tu)(tu)(tu)層，這一涂(tu)(tu)(tu)裝(zhuang)工藝過程(cheng)稱之為陰極電泳。
