鍍(du)鋅(xin)(xin)(xin)帶(dai)鋼的鋅(xin)(xin)(xin)層(ceng)特性 電鍍(du)鋅(xin)(xin)(xin)層(ceng)是不(bu)能形(xing)成鋅(xin)(xin)(xin)花(hua)(hua)的，熱(re)鍍(du)鋅(xin)(xin)(xin)層(ceng)則有鋅(xin)(xin)(xin)花(hua)(hua)，其(qi)形(xing)成過程(cheng)如下：當鍍(du)鋅(xin)(xin)(xin)帶(dai)從鋅(xin)(xin)(xin)鍋(guo)出(chu)來后，經氣刀的噴吹(chui)，大(da)量(liang)鋅(xin)(xin)(xin)液被(bei)吹(chui)回鋅(xin)(xin)(xin)鍋(guo)，這(zhe)時帶(dai)鋼表(biao)(biao)面還有純鋅(xin)(xin)(xin)層(ceng)，呈液 態(tai)附在(zai)鋼板表(biao)(biao)面，在(zai)鋼板表(biao)(biao)面形(xing)成大(da)量(liang)結晶核，隨著鋼板上升冷卻，使結晶核慢(man)慢(man)長成鋅(xin)(xin)(xin)花(hua)(hua)。冷卻速(su)(su)度越快鋅(xin)(xin)(xin)花(hua)(hua)越小(xiao)，冷卻速(su)(su)度越慢(man)鋅(xin)(xin)(xin)花(hua)(hua)越大(da)。熱(re)鍍(du)鋅(xin)(xin)(xin)帶(dai)鋼在(zai)我國(guo)市場一直是緊缺(que)品種。從20世紀(ji)90年代(dai)中期以來，每年都要從國(guo)外進口80-100萬(wan)t左(zuo)右。隨著國(guo)內經濟的發展(zhan)，尤其(qi)是汽車(che)、家電及建筑業的發展(zhan)，對鍍(du)鋅(xin)(xin)(xin)帶(dai)鋼的需求量(liang)也大(da)大(da)增加。

熱鍍鋅價格鍍鋅鋼板的表面鍍鋅主要采用的方法是熱鍍鋅。巫溪熱鍍鋅熱(re)鍍(du)(du)(du)鋅(xin)(xin)是由較古老的(de)熱(re)鍍(du)(du)(du)方法發展(zhan)而來的(de)，自從1836年(nian)法國把(ba)熱(re)鍍(du)(du)(du)鋅(xin)(xin)應用(yong)于工業以(yi)來，已經有一百七十年(nian)的(de)歷史了。然而，熱(re)鍍(du)(du)(du)鋅(xin)(xin)工業是近(jin)(jin)三十年(nian)來伴隨(sui)冷軋帶鋼的(de)飛速發展(zhan)而得(de)到(dao)了大規模發展(zhan)。鍍(du)(du)(du)鋅(xin)(xin)溶液(ye)(ye)(ye)(ye)有氰(qing)(qing)(qing)(qing)化(hua)物(wu)(wu)鍍(du)(du)(du)液(ye)(ye)(ye)(ye)和(he)(he)無氰(qing)(qing)(qing)(qing)鍍(du)(du)(du)液(ye)(ye)(ye)(ye)兩類(lei)。氰(qing)(qing)(qing)(qing)化(hua)物(wu)(wu)鍍(du)(du)(du)液(ye)(ye)(ye)(ye)中分微(wei)(wei)氰(qing)(qing)(qing)(qing)、低(di)氰(qing)(qing)(qing)(qing)、中氰(qing)(qing)(qing)(qing)、和(he)(he)高氰(qing)(qing)(qing)(qing)幾類(lei)。無氰(qing)(qing)(qing)(qing)鍍(du)(du)(du)液(ye)(ye)(ye)(ye)有堿性(xing)鋅(xin)(xin)酸鹽鍍(du)(du)(du)液(ye)(ye)(ye)(ye)、銨鹽鍍(du)(du)(du)液(ye)(ye)(ye)(ye)、硫酸鹽鍍(du)(du)(du)液(ye)(ye)(ye)(ye)及(ji)無氨氯化(hua)物(wu)(wu)鍍(du)(du)(du)液(ye)(ye)(ye)(ye)等。氰(qing)(qing)(qing)(qing)化(hua)鍍(du)(du)(du)鋅(xin)(xin)溶液(ye)(ye)(ye)(ye)均鍍(du)(du)(du)能力(li)好，得(de)到(dao)的(de)鍍(du)(du)(du)層光滑細(xi)致，在生產中被長期采用(yong)。但由于氰(qing)(qing)(qing)(qing)化(hua)物(wu)(wu)劇毒(du)，對環境污(wu)染嚴(yan)重，近(jin)(jin)年(nian)來已趨(qu)向于采用(yong)低(di)氰(qing)(qing)(qing)(qing)、微(wei)(wei)氰(qing)(qing)(qing)(qing)、無氰(qing)(qing)(qing)(qing)鍍(du)(du)(du)鋅(xin)(xin)溶液(ye)(ye)(ye)(ye)。

鍍(du)鋅(xin)方管是(shi)一(yi)種(zhong)(zhong)具以熱(re)軋或冷軋鍍(du)鋅(xin)帶鋼(gang)(gang)(gang)或鍍(du)鋅(xin)卷板為坯(pi)料(liao)經冷彎曲加工成型后再經高(gao)頻焊接制(zhi)成的(de)方形截面(mian)形狀尺寸的(de)空心方形的(de)截面(mian)型鋼(gang)(gang)(gang)鋼(gang)(gang)(gang)管；鍍(du)鋅(xin)卷或將事先做(zuo)好的(de)冷彎空心型鋼(gang)(gang)(gang)管再經熱(re)浸鍍(du)鋅(xin)加工而(er)成的(de)鍍(du)鋅(xin)方矩管。鍍(du)鋅(xin)量是(shi)表(biao)示鍍(du)鋅(xin)板鋅(xin)層厚度的(de)一(yi)個普(pu)遍采用的(de)有效方法。鍍(du)鋅(xin)量的(de)單位為g/m2。鍍(du)鋅(xin)層通過鈍化處理，可減少潮溫貯運條(tiao)件下產生折銹蝕(白銹) 。但這(zhe)種(zhong)(zhong)化學處理的(de)防腐(fu)蝕性能(neng)是(shi)有限的(de)，而(er)且，妨(fang)礙(ai)大多數(shu)涂料(liao)的(de)附著性。這(zhe)種(zhong)(zhong)處理一(yi)般(ban)不用在鋅(xin)鐵合(he)金鍍(du)層，除光整表(biao)面(mian)外，作為常規，生產廠對其他類型的(de)鍍(du)鋅(xin)層均進行鈍化處理。
