1. 電解拋(pao)光工藝(yi)流程(cheng)

不(bu)銹鋼(gang)管(guan)化學(xue)除油→熱(re)水(shui)(shui)沖(chong)(chong)洗(xi)(xi)→清(qing)水(shui)(shui)漂洗(xi)(xi)→烘干→電(dian)解拋(pao)光→清(qing)水(shui)(shui)沖(chong)(chong)洗(xi)(xi)→熱(re)水(shui)(shui)沖(chong)(chong)洗(xi)(xi)→清(qing)水(shui)(shui)漂洗(xi)(xi)→(鈍化處理(li)→熱(re)水(shui)(shui)沖(chong)(chong)洗(xi)(xi)→清(qing)水(shui)(shui)漂洗(xi)(xi)→中和→熱(re)水(shui)(shui)沖(chong)(chong)洗(xi)(xi)→)→烘干→檢驗→包裝→出廠。

2. 化學除油

化學除(chu)油配(pei)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：80℃~90℃;時間：15min.

3. 電(dian)解(jie)拋光工(gong)藝

電(dian)(dian)解拋(pao)(pao)光(guang)(guang)工(gong)藝(yi)主要包(bao)括電(dian)(dian)解液的配(pei)(pei)制，電(dian)(dian)解液的溫度，電(dian)(dian)解拋(pao)(pao)光(guang)(guang)的時間、電(dian)(dian)流(liu)和(he)電(dian)(dian)壓等。下面介(jie)紹幾種常(chang)用的不銹鋼電(dian)(dian)解拋(pao)(pao)光(guang)(guang)液配(pei)(pei)方及(ji)其工(gong)藝(yi)參數。這(zhe)些配(pei)(pei)方所用的化學藥品都是最普(pu)通的容易購買到的，而(er)且(qie)工(gong)藝(yi)要求的溫度都比(bi)較(jiao)低(di)，拋(pao)(pao)光(guang)(guang)所需時間也較(jiao)短(duan)，非(fei)常(chang)適(shi)合于大生產(chan)的要求 而(er)日(ri)地光(guang)(guang)效果理想可靠，見表11-1。

4. 鈍化
