簡介怎樣使35號無縫管的(de)磷(lin)化(hua)處理(li)達(da)到理(li)想(xiang)的(de)效果
35號無縫管磷化處(chu)理(li)后的工件為正黑色(se)。正確使用藥液處(chu)理(li)的工件油黑發亮,藥膜堅固,摩(mo)擦不掉,長期(qi)不銹。達到令人滿(man)意的效果。
但是,在實(shi)際使(shi)用中,由(you)于用戶(hu)對此(ci)產品了解(jie)不(bu)足,使(shi)用不(bu)當,有(you)時卻(que)難(nan)以達到(dao)(dao)令人滿意的(de)(de)(de)(de)(de)程度。任何工作(zuo)都有(you)技巧,它(ta)來(lai)自(zi)對此(ci)事物的(de)(de)(de)(de)(de)較深刻的(de)(de)(de)(de)(de)認(ren)識和了解(jie)。鋼鐵磷化(hua)液的(de)(de)(de)(de)(de)使(shi)用也是如此(ci),如使(shi)用不(bu)當就(jiu)會(hui)使(shi)它(ta)的(de)(de)(de)(de)(de)功效降低,甚至達不(bu)到(dao)(dao)工藝要(yao)求。因此(ci),深入了解(jie)其(qi)性能,正確使(shi)用鋼鐵磷化(hua)液就(jiu)成(cheng)了普及新技術的(de)(de)(de)(de)(de)重要(yao)問題。
35號無縫管磷(lin)化(hua)(hua)液(ye)使用(yong)(yong)中最關鍵的(de)環節是工(gong)(gong)(gong)件(jian)(jian)的(de)預先清(qing)洗(xi)(xi),工(gong)(gong)(gong)件(jian)(jian)在磷(lin)化(hua)(hua)前必須用(yong)(yong)除(chu)油(you)清(qing)洗(xi)(xi)劑進行(xing)除(chu)油(you)清(qing)洗(xi)(xi)(批量生(sheng)產時(shi)可采用(yong)(yong)堿性煮沸除(chu)油(you)),注意清(qing)洗(xi)(xi)液(ye)表面(mian)漂(piao)浮的(de)油(you)膜不(bu)(bu)要在工(gong)(gong)(gong)件(jian)(jian)取出時(shi)再(zai)次污染工(gong)(gong)(gong)件(jian)(jian)。然后(hou)用(yong)(yong)濃度(du)不(bu)(bu)低于15%的(de)鹽酸除(chu)銹(xiu),(看似無銹(xiu)的(de)工(gong)(gong)(gong)件(jian)(jian)也應在鹽酸中進行(xing)表面(mian)‘活(huo)化(hua)(hua)’)不(bu)(bu)能草率(lv)了事。否則會影響磷(lin)化(hua)(hua)工(gong)(gong)(gong)部(bu)效果。
