不(bu)(bu)銹(xiu)鋼(gang)管(guan)使我(wo)們在(zai)(zai)工業(ye)上常見的(de)(de)使用材(cai)質(zhi),一般不(bu)(bu)銹(xiu)鋼(gang)是(shi)不(bu)(bu)容易生銹(xiu)的(de)(de),但(dan)是(shi)可能因(yin)為環境等會因(yin)素還(huan)可能會導致不(bu)(bu)銹(xiu)鋼(gang)管(guan)有(you)銹(xiu)跡的(de)(de),我(wo)們在(zai)(zai)發現不(bu)(bu)銹(xiu)鋼(gang)發生銹(xiu)跡時,需要如何進行 的(de)(de)處(chu)理,下(xia)面我(wo)們大家提供的(de)(de)兩種 方法進行處(chu)理。

:是(shi)化(hua)(hua)(hua)學(xue)腐(fu)(fu)蝕:表(biao)面(mian)污(wu)染:附著(zhu)在(zai)工件表(biao)面(mian)的(de)油污(wu)、灰塵及酸、堿、鹽等在(zai)一定條件轉化(hua)(hua)(hua)為腐(fu)(fu)蝕介質,與不銹(xiu)(xiu)(xiu)鋼(gang)件中的(de)某些成(cheng)分發生(sheng)(sheng)(sheng)化(hua)(hua)(hua)學(xue)反(fan)應,產生(sheng)(sheng)(sheng)化(hua)(hua)(hua)學(xue)腐(fu)(fu)蝕而生(sheng)(sheng)(sheng)銹(xiu)(xiu)(xiu)。表(biao)面(mian)劃傷:各種(zhong)劃傷對鈍化(hua)(hua)(hua)膜(mo)的(de)破壞(huai),使不銹(xiu)(xiu)(xiu)鋼(gang)保護能力(li)降低,易與化(hua)(hua)(hua)學(xue)介質發生(sheng)(sheng)(sheng)反(fan)應,產生(sheng)(sheng)(sheng)化(hua)(hua)(hua)學(xue)腐(fu)(fu)蝕而生(sheng)(sheng)(sheng)銹(xiu)(xiu)(xiu)。清洗(xi):酸洗(xi)鈍化(hua)(hua)(hua)后清洗(xi)不干凈(jing)造成(cheng)殘液存留,直(zhi)接腐(fu)(fu)蝕不銹(xiu)(xiu)(xiu)鋼(gang)件。

第二:是電(dian)(dian)(dian)化(hua)(hua)(hua)學腐(fu)(fu)(fu)(fu)(fu)(fu)蝕(shi)(shi)(shi)(shi):碳鋼(gang)污(wu)染:與(yu)(yu)(yu)碳鋼(gang)件接(jie)觸造(zao)(zao)成(cheng)(cheng)的(de)(de)劃傷與(yu)(yu)(yu)腐(fu)(fu)(fu)(fu)(fu)(fu)蝕(shi)(shi)(shi)(shi)介(jie)質(zhi)形成(cheng)(cheng)原(yuan)電(dian)(dian)(dian)池(chi)而(er)(er)產(chan)生(sheng)電(dian)(dian)(dian)化(hua)(hua)(hua)學腐(fu)(fu)(fu)(fu)(fu)(fu)蝕(shi)(shi)(shi)(shi)。切割:割渣、飛濺等易生(sheng)銹物(wu)(wu)質(zhi)的(de)(de)附著(zhu)與(yu)(yu)(yu)腐(fu)(fu)(fu)(fu)(fu)(fu)蝕(shi)(shi)(shi)(shi)介(jie)質(zhi)形成(cheng)(cheng)原(yuan)電(dian)(dian)(dian)池(chi)而(er)(er)產(chan)生(sheng)電(dian)(dian)(dian)化(hua)(hua)(hua)學腐(fu)(fu)(fu)(fu)(fu)(fu)。烤(kao)校:火焰(yan)加熱(re)區域(yu)的(de)(de)成(cheng)(cheng)份(fen)與(yu)(yu)(yu)金(jin)相組織發生(sheng)變化(hua)(hua)(hua)而(er)(er)不(bu)(bu)均(jun)勻,與(yu)(yu)(yu)腐(fu)(fu)(fu)(fu)(fu)(fu)蝕(shi)(shi)(shi)(shi)介(jie)質(zhi)形成(cheng)(cheng)原(yuan)電(dian)(dian)(dian)池(chi)而(er)(er)產(chan)生(sheng)電(dian)(dian)(dian)化(hua)(hua)(hua)學腐(fu)(fu)(fu)(fu)(fu)(fu)蝕(shi)(shi)(shi)(shi)。焊(han)接(jie):焊(han)接(jie)區域(yu)的(de)(de)物(wu)(wu)理缺(que)陷(xian)和化(hua)(hua)(hua)學缺(que)陷(xian)與(yu)(yu)(yu)腐(fu)(fu)(fu)(fu)(fu)(fu)蝕(shi)(shi)(shi)(shi)介(jie)質(zhi)形成(cheng)(cheng)原(yuan)電(dian)(dian)(dian)池(chi)而(er)(er)產(chan)生(sheng)電(dian)(dian)(dian)化(hua)(hua)(hua)學腐(fu)(fu)(fu)(fu)(fu)(fu)蝕(shi)(shi)(shi)(shi)。材(cai)質(zhi):不(bu)(bu)銹鋼(gang)材(cai)質(zhi)的(de)(de)化(hua)(hua)(hua)學缺(que)陷(xian)和表(biao)面物(wu)(wu)理缺(que)陷(xian)有利于與(yu)(yu)(yu)腐(fu)(fu)(fu)(fu)(fu)(fu)蝕(shi)(shi)(shi)(shi)介(jie)質(zhi)形成(cheng)(cheng)原(yuan)電(dian)(dian)(dian)池(chi)而(er)(er)產(chan)生(sheng)電(dian)(dian)(dian)化(hua)(hua)(hua)學腐(fu)(fu)(fu)(fu)(fu)(fu)蝕(shi)(shi)(shi)(shi)。鈍(dun)(dun)化(hua)(hua)(hua):酸洗(xi)(xi)(xi)鈍(dun)(dun)化(hua)(hua)(hua)效(xiao)果不(bu)(bu)好(hao)造(zao)(zao)成(cheng)(cheng)不(bu)(bu)銹鋼(gang)表(biao)面鈍(dun)(dun)化(hua)(hua)(hua)膜不(bu)(bu)均(jun)勻或較薄,易于形成(cheng)(cheng)電(dian)(dian)(dian)化(hua)(hua)(hua)學腐(fu)(fu)(fu)(fu)(fu)(fu)蝕(shi)(shi)(shi)(shi)。清(qing)洗(xi)(xi)(xi):存留的(de)(de)酸洗(xi)(xi)(xi)鈍(dun)(dun)化(hua)(hua)(hua)殘液與(yu)(yu)(yu)不(bu)(bu)銹鋼(gang)發生(sheng)化(hua)(hua)(hua)學腐(fu)(fu)(fu)(fu)(fu)(fu)蝕(shi)(shi)(shi)(shi)的(de)(de)生(sheng)成(cheng)(cheng)物(wu)(wu)與(yu)(yu)(yu)不(bu)(bu)銹鋼(gang)件形成(cheng)(cheng)電(dian)(dian)(dian)化(hua)(hua)(hua)學腐(fu)(fu)(fu)(fu)(fu)(fu)蝕(shi)(shi)(shi)(shi)。
