3. 電解拋光(guang)工藝

電(dian)(dian)解(jie)拋光(guang)(guang)工藝(yi)(yi)主要包括電(dian)(dian)解(jie)液的(de)(de)配(pei)制，電(dian)(dian)解(jie)液的(de)(de)溫度，電(dian)(dian)解(jie)拋光(guang)(guang)的(de)(de)時(shi)間(jian)、電(dian)(dian)流和電(dian)(dian)壓等。下(xia)面介紹(shao)幾種常用(yong)的(de)(de)不銹鋼電(dian)(dian)解(jie)拋光(guang)(guang)液配(pei)方及其(qi)工藝(yi)(yi)參(can)數。這些配(pei)方所用(yong)的(de)(de)化學藥品都是最普(pu)通(tong)的(de)(de)容易(yi)購(gou)買到的(de)(de)，而且(qie)工藝(yi)(yi)要求的(de)(de)溫度都比較(jiao)(jiao)低，拋光(guang)(guang)所需時(shi)間(jian)也較(jiao)(jiao)短，非常適合于大(da)生產(chan)的(de)(de)要求 而日地光(guang)(guang)效果理(li)想可(ke)靠，見表(biao)11-1。
