1. 電解拋光工藝流程

不銹鋼管化學除油→熱(re)(re)水(shui)(shui)沖(chong)洗(xi)(xi)→清水(shui)(shui)漂(piao)洗(xi)(xi)→烘干(gan)→電解拋光(guang)→清水(shui)(shui)沖(chong)洗(xi)(xi)→熱(re)(re)水(shui)(shui)沖(chong)洗(xi)(xi)→清水(shui)(shui)漂(piao)洗(xi)(xi)→(鈍化處理→熱(re)(re)水(shui)(shui)沖(chong)洗(xi)(xi)→清水(shui)(shui)漂(piao)洗(xi)(xi)→中和(he)→熱(re)(re)水(shui)(shui)沖(chong)洗(xi)(xi)→)→烘干(gan)→檢驗→包裝(zhuang)→出廠。

2. 化(hua)學除油(you)

化學(xue)除油配方：

NaOH: 50g/L~80g/L;  Na₂CO₃: 20g/L~30g/L;  Na₃PO₃: 20g/L~30g/L;

洗衣(yi)粉：7g/L~10g/L;溫度(du)：80℃~90℃;時(shi)間：15min.

3. 電解拋光工(gong)藝(yi)

電(dian)(dian)(dian)解拋光(guang)工(gong)藝主(zhu)要(yao)包括電(dian)(dian)(dian)解液(ye)的配制，電(dian)(dian)(dian)解液(ye)的溫(wen)度(du)，電(dian)(dian)(dian)解拋光(guang)的時(shi)間、電(dian)(dian)(dian)流(liu)和電(dian)(dian)(dian)壓等(deng)。下面介(jie)紹幾(ji)種常用的不(bu)銹(xiu)鋼(gang)電(dian)(dian)(dian)解拋光(guang)液(ye)配方及其工(gong)藝參數(shu)。這些(xie)配方所用的化學藥品(pin)都是最普通的容易購(gou)買到的，而且工(gong)藝要(yao)求的溫(wen)度(du)都比較(jiao)低，拋光(guang)所需時(shi)間也較(jiao)短，非(fei)常適合于大生產(chan)的要(yao)求 而日地光(guang)效果理想可靠，見(jian)表11-1。

4. 鈍(dun)化
