熱(re)鍍鋅卷板(ban)價格行業(ye)統(tong)(tong)計數據顯示(shi)，十一月國(guo)內粗鋼(gang)日(ri)均產量為兩百零九(jiu)萬噸，環比下(xia)降3.3%，創出今年(nian)以(yi)來水平，但(dan)是當前減產受到(dao)季(ji)節性(xing)因(yin)素支撐，市(shi)場(chang)對數據有效性(xing)提出質疑。鍍鋅卷工(gong)業(ye)品而(er)言，近(jin)期陸續(xu)公布的重要數據中性(xing)偏(pian)多。但(dan)值得注(zhu)意的是，同年(nian)十一月熱(re)鍍鋅卷板(ban)價格工(gong)業(ye)增(zeng)(zeng)加(jia)值和投資(zi)增(zeng)(zeng)速放緩，進(jin)一步印證了(le)國(guo)內總需求(qiu)乏力，工(gong)業(ye)復蘇形勢不容(rong)樂觀(guan)。加(jia)上未來經濟結構調整等因(yin)素，工(gong)業(ye)品價格反彈高度(du)將有限(xian)。傳(chuan)統(tong)(tong)需求(qiu)淡季(ji)效應還(huan)在持續(xu)不斷地發酵(jiao)，冬儲效果不佳。雖然數據顯示(shi)供應壓力開始減輕，但(dan)是目前處于鋼(gang)鐵需求(qiu)淡季(ji)，市(shi)場(chang)成交萎縮，下(xia)游采購(gou)遲遲未能有效跟(gen)進(jin)，市(shi)場(chang)信(xin)心不足(zu)，鍍鋅鋼(gang)板(ban)貿易商(shang)囤貨(huo)現象(xiang)也不明顯。

鍍(du)(du)(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)板的表面鍍(du)(du)(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)主要采(cai)用(yong)(yong)的方法是(shi)熱(re)(re)鍍(du)(du)(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)。熱(re)(re)鍍(du)(du)(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)是(shi)由(you)較古老的熱(re)(re)鍍(du)(du)(du)(du)(du)(du)(du)(du)方法發展而(er)(er)來(lai)的，自從1836年法國把熱(re)(re)鍍(du)(du)(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)應用(yong)(yong)于(yu)工業以來(lai)，已(yi)經有一百七十年的歷(li)史了。然而(er)(er)，熱(re)(re)鍍(du)(du)(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)工業是(shi)近三十年來(lai)伴隨冷(leng)軋帶鋼(gang)的飛速(su)發展而(er)(er)得到(dao)了大(da)規模發展。鍍(du)(du)(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)溶液(ye)(ye)(ye)有氰(qing)(qing)化(hua)(hua)物(wu)(wu)鍍(du)(du)(du)(du)(du)(du)(du)(du)液(ye)(ye)(ye)和無氰(qing)(qing)鍍(du)(du)(du)(du)(du)(du)(du)(du)液(ye)(ye)(ye)兩類。氰(qing)(qing)化(hua)(hua)物(wu)(wu)鍍(du)(du)(du)(du)(du)(du)(du)(du)液(ye)(ye)(ye)中(zhong)分(fen)微(wei)氰(qing)(qing)、低(di)氰(qing)(qing)、中(zhong)氰(qing)(qing)、和高氰(qing)(qing)幾類。無氰(qing)(qing)鍍(du)(du)(du)(du)(du)(du)(du)(du)液(ye)(ye)(ye)有堿性鋅(xin)(xin)(xin)酸鹽(yan)鍍(du)(du)(du)(du)(du)(du)(du)(du)液(ye)(ye)(ye)、銨鹽(yan)鍍(du)(du)(du)(du)(du)(du)(du)(du)液(ye)(ye)(ye)、硫酸鹽(yan)鍍(du)(du)(du)(du)(du)(du)(du)(du)液(ye)(ye)(ye)及無氨氯化(hua)(hua)物(wu)(wu)鍍(du)(du)(du)(du)(du)(du)(du)(du)液(ye)(ye)(ye)等。氰(qing)(qing)化(hua)(hua)鍍(du)(du)(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)溶液(ye)(ye)(ye)均鍍(du)(du)(du)(du)(du)(du)(du)(du)能力好，得到(dao)的鍍(du)(du)(du)(du)(du)(du)(du)(du)層光(guang)滑(hua)細致，在生產(chan)中(zhong)被長期采(cai)用(yong)(yong)。但由(you)于(yu)氰(qing)(qing)化(hua)(hua)物(wu)(wu)劇(ju)毒，對環境污染嚴重，近年來(lai)已(yi)趨(qu)向于(yu)采(cai)用(yong)(yong)低(di)氰(qing)(qing)、微(wei)氰(qing)(qing)、無氰(qing)(qing)鍍(du)(du)(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)溶液(ye)(ye)(ye)。

鍍鋅價格鍍鋅鋼板是為防止鋼板表面遭受腐蝕，延長其使用壽命，在鋼板表面涂以一層金屬鋅，這種涂鋅的薄鋼板稱為鍍鋅板。酒鋼鍍鋅價格按生產(chan)及加(jia)工(gong)方法(fa)可分(fen)為以下幾(ji)類：熱浸鍍鋅鋼(gang)(gang)板(ban)(ban)(ban)。將薄鋼(gang)(gang)板(ban)(ban)(ban)浸入熔 微(wei)商貨源(yuan)解的(de)鋅槽中(zhong)，使其表面粘附一層鋅的(de)薄鋼(gang)(gang)板(ban)(ban)(ban)。目前主要采用連(lian)續(xu)鍍鋅工(gong)藝(yi)生產(chan)，即把成卷(juan)的(de)鋼(gang)(gang)板(ban)(ban)(ban)連(lian)續(xu)浸在熔解有鋅的(de)鍍槽中(zhong)制成鍍鋅鋼(gang)(gang)板(ban)(ban)(ban)；合(he)金化鍍鋅鋼(gang)(gang)板(ban)(ban)(ban)。這種鋼(gang)(gang)板(ban)(ban)(ban)也是用熱浸法(fa)制造，但(dan)在出(chu)槽后，立即把它加(jia)熱到５００℃左(zuo)右，使其生成鋅和鐵的(de)合(he)金被膜。這種鍍鋅板(ban)(ban)(ban)具(ju)有良好的(de)涂(tu)料的(de)密著性和焊接性。

鍍(du)(du)(du)(du)鋅(xin)(xin)鋼(gang)板按用(yong)(yong)(yong)途又可分(fen)為一(yi)(yi)般(ban)用(yong)(yong)(yong)、屋頂(ding)用(yong)(yong)(yong)、建(jian)筑外側板用(yong)(yong)(yong)、結構(gou)(gou)用(yong)(yong)(yong)、瓦(wa)壟板用(yong)(yong)(yong)、拉伸用(yong)(yong)(yong)和深沖(chong)用(yong)(yong)(yong)等鍍(du)(du)(du)(du)鋅(xin)(xin)鋼(gang)板。對(dui)于一(yi)(yi)般(ban)防保護用(yong)(yong)(yong)鍍(du)(du)(du)(du)層(ceng)，可以(yi)采用(yong)(yong)(yong)堿性(xing)鋅(xin)(xin)酸鹽鍍(du)(du)(du)(du)鋅(xin)(xin)彩色(se)鈍化(hua)(hua)工藝(yi)(yi)。有時為了(le)產品的(de)配色(se)需要，也可以(yi)采用(yong)(yong)(yong)藍白色(se)鈍化(hua)(hua)工藝(yi)(yi)，比(bi)如軍綠色(se)鈍化(hua)(hua)、黑色(se)鈍化(hua)(hua)等。為提高鋼(gang)管(guan)(guan)的(de)耐腐蝕(shi)(shi)性(xing)能，對(dui)一(yi)(yi)般(ban)鋼(gang)管(guan)(guan)進行鍍(du)(du)(du)(du)鋅(xin)(xin)。鍍(du)(du)(du)(du)鋅(xin)(xin)卷分(fen)熱鍍(du)(du)(du)(du)鋅(xin)(xin)和電(dian)鍍(du)(du)(du)(du)鋅(xin)(xin)兩(liang)種(zhong)，熱鍍(du)(du)(du)(du)鋅(xin)(xin)鍍(du)(du)(du)(du)鋅(xin)(xin)層(ceng)厚，電(dian)鍍(du)(du)(du)(du)鋅(xin)(xin)成本低(di)，表面不是很光滑(hua)。吹(chui)氧焊(han)管(guan)(guan)：用(yong)(yong)(yong)作煉(lian)鋼(gang)吹(chui)氧用(yong)(yong)(yong)管(guan)(guan)，一(yi)(yi)般(ban)用(yong)(yong)(yong)小口(kou)徑(jing)的(de)焊(han)接鋼(gang)管(guan)(guan)，規格(ge)由3/8-2寸八種(zhong)。用(yong)(yong)(yong)08、10、15、20或者(zhe)195-Q235的(de)鋼(gang)帶制(zhi)作成的(de)，為了(le)防腐蝕(shi)(shi)，有得進行滲鋁處理。鍍(du)(du)(du)(du)鋅(xin)(xin)其防護作用(yong)(yong)(yong)更強(qiang)，抗腐蝕(shi)(shi)能力強(qiang)。整個(ge)結構(gou)(gou)由鋅(xin)(xin)，形成致密的(de)四元結晶(jing)體，此結晶(jing)體在鋼(gang)板上形成一(yi)(yi)層(ceng)屏(ping)障， 因而有效的(de)防止(zhi)腐蝕(shi)(shi)因子穿透(tou)。 耐腐蝕(shi)(shi)性(xing)來自鋅(xin)(xin)的(de)障礙層(ceng)保護功能強(qiang)。
