用(yong)(yong)電鍍(du)(du)(du)(du)(du)(du)法制造這(zhe)種鍍(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)板(ban)(ban)具有(you)良好的加工性(xing)。但(dan)鍍(du)(du)(du)(du)(du)(du)層(ceng)較薄，耐腐蝕性(xing)不如熱浸法鍍(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)板(ban)(ban)；單面(mian)鍍(du)(du)(du)(du)(du)(du)和雙面(mian)差(cha)鍍(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)板(ban)(ban)。單面(mian)鍍(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)板(ban)(ban)，即只在一面(mian)鍍(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)的產品。在焊接(jie)、涂(tu)(tu)裝(zhuang)、防(fang)銹處(chu)理(li)、加工等方面(mian)，具有(you)比雙面(mian)鍍(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)板(ban)(ban)好的適應性(xing)。為克服單面(mian)未(wei)涂(tu)(tu)鋅(xin)(xin)(xin)的缺點，又(you)(you)有(you)一種在另面(mian)涂(tu)(tu)以薄層(ceng)鋅(xin)(xin)(xin)的鍍(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)板(ban)(ban)，即雙面(mian)差(cha)鍍(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)板(ban)(ban)；合金(jin)、復合鍍(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)板(ban)(ban)。它是(shi)用(yong)(yong)鋅(xin)(xin)(xin)和其他金(jin)屬如鉛(qian)、鋅(xin)(xin)(xin)制成(cheng)合金(jin)乃(nai)至復合鍍(du)(du)(du)(du)(du)(du)成(cheng)的鋼(gang)板(ban)(ban)。這(zhe)種鋼(gang)板(ban)(ban)既具有(you)防(fang)銹性(xing)能(neng)，又(you)(you)有(you)良好的涂(tu)(tu)裝(zhuang)性(xing)能(neng)。 除上述五種外(wai)，還有(you)彩色鍍(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)板(ban)(ban)、印花(hua)涂(tu)(tu)裝(zhuang)鍍(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)板(ban)(ban)、聚氯乙(yi)烯(xi)疊層(ceng)鍍(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)板(ban)(ban)等。但(dan)目(mu)前常用(yong)(yong)的仍為熱浸鍍(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)板(ban)(ban)。 鍍(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)板(ban)(ban)按用(yong)(yong)途又(you)(you)可分為一般用(yong)(yong)、屋頂用(yong)(yong)、建筑外(wai)側(ce)板(ban)(ban)用(yong)(yong)、結構用(yong)(yong)、瓦(wa)壟板(ban)(ban)用(yong)(yong)、拉伸用(yong)(yong)和深沖用(yong)(yong)等鍍(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)板(ban)(ban)。

近期鋼價延續低(di)迷，隨(sui)著通國(guo)規模的(de)酷暑和(he)旱季到來(lai)，熱鍍鋅(xin)(xin)卷(juan)板價格商(shang)場逐(zhu)漸(jian)進入需要旺季，海內鋼鐵商(shang)場或將窄幅調(diao)整。在決策層兩手抓制度(du)(du)措(cuo)施(shi)落(luo)實狀況(kuang)、貨(huo)銀本(ben)位度(du)(du)定向寬松力(li)度(du)(du)加大的(de)直觀層面利好(hao)牽動下，商(shang)場信念逐(zhu)漸(jian)趨穩，短期海內鋼價無望止跌企穩;另一上(shang)面，以后鋼價殺跌電(dian)能有(you)余，而上(shang)漲也(ye)仍然屏障重重。熱鍍鋅(xin)(xin)卷(juan)板價格價錢或將長(chang)期在于低(di)位運(yun)行(xing)場面。

熱(re)(re)鍍(du)(du)鋅(xin)(xin)卷板(ban)現貨消息(xi)：熱(re)(re)鍍(du)(du)鋅(xin)(xin)產(chan)品廣(guang)泛用于建筑、家(jia)電(dian)、車船(chuan)、容器制造業(ye)、機電(dian)業(ye)等，幾乎(hu)涉及到衣食(shi)住行(xing)(xing)各個領域。近(jin)年來，世界鍍(du)(du)鋅(xin)(xin)鋼(gang)板(ban)需(xu)求(qiu)量不(bu)斷(duan)增加，產(chan)量增長也很(hen)快，在美、日等鋼(gang)材生產(chan)大國，熱(re)(re)鍍(du)(du)鋅(xin)(xin)鋼(gang)板(ban)在鋼(gang)材中所占比例(li)已高達(da)13%-15%。 熱(re)(re)鍍(du)(du)鋅(xin)(xin)卷板(ban)現貨消息(xi)：近(jin)來，汽(qi)(qi)車行(xing)(xing)業(ye)越來越重(zhong)視材料的使用壽(shou)命，用涂漆冷軋鋼(gang)板(ban)已不(bu)能滿足耐腐(fu)蝕(shi)方(fang)面(mian)的要求(qiu)。在這種情況下(xia)，耐腐(fu)蝕(shi)性優(you)良且(qie)成本(ben)低廉的熱(re)(re)鍍(du)(du)鋅(xin)(xin)板(ban)開(kai)始(shi)普遍受到了汽(qi)(qi)車廠家(jia)的青睞。

彩涂板價格鍍鋅鋼板按用途又可分為一般用、屋頂用、建筑外側板用、結構用、瓦壟板用、拉伸用和深沖用等鍍鋅鋼板。懷化彩涂板對于一(yi)般(ban)防保護(hu)用(yong)(yong)鍍(du)(du)層，可以采用(yong)(yong)堿性鋅(xin)(xin)酸鹽鍍(du)(du)鋅(xin)(xin)彩(cai)色(se)鈍(dun)化工藝。有(you)時為了產品的(de)(de)配色(se)需要，也可以采用(yong)(yong)藍白色(se)鈍(dun)化工藝，比(bi)如軍綠色(se)鈍(dun)化、黑色(se)鈍(dun)化等(deng)。為提高鋼(gang)管(guan)(guan)的(de)(de)耐(nai)腐蝕(shi)性能(neng)，對一(yi)般(ban)鋼(gang)管(guan)(guan)進行鍍(du)(du)鋅(xin)(xin)。鍍(du)(du)鋅(xin)(xin)卷(juan)分熱(re)鍍(du)(du)鋅(xin)(xin)和電鍍(du)(du)鋅(xin)(xin)兩種，熱(re)鍍(du)(du)鋅(xin)(xin)鍍(du)(du)鋅(xin)(xin)層厚，電鍍(du)(du)鋅(xin)(xin)成(cheng)本(ben)低，表面不(bu)是(shi)很光滑。吹(chui)氧(yang)焊管(guan)(guan)：用(yong)(yong)作煉鋼(gang)吹(chui)氧(yang)用(yong)(yong)管(guan)(guan)，一(yi)般(ban)用(yong)(yong)小口徑的(de)(de)焊接鋼(gang)管(guan)(guan)，規格由(you)(you)3/8-2寸八種。用(yong)(yong)08、10、15、20或者195-Q235的(de)(de)鋼(gang)帶制作成(cheng)的(de)(de)，為了防腐蝕(shi)，有(you)得進行滲(shen)鋁處理。鍍(du)(du)鋅(xin)(xin)其防護(hu)作用(yong)(yong)更強(qiang)，抗腐蝕(shi)能(neng)力(li)強(qiang)。整個結(jie)構由(you)(you)鋅(xin)(xin)，形(xing)成(cheng)致密的(de)(de)四(si)元結(jie)晶體，此結(jie)晶體在鋼(gang)板上(shang)形(xing)成(cheng)一(yi)層屏障(zhang)， 因而有(you)效的(de)(de)防止腐蝕(shi)因子(zi)穿(chuan)透(tou)。 耐(nai)腐蝕(shi)性來自鋅(xin)(xin)的(de)(de)障(zhang)礙層保護(hu)功能(neng)強(qiang)。

熱(re)鍍(du)鋅卷板價(jia)格行業(ye)統(tong)(tong)計數(shu)據(ju)顯(xian)示，十(shi)一月國內粗鋼日均產量為兩百(bai)零九萬噸，環比下(xia)降3.3%，創出今(jin)年(nian)以來水平，但是當前減產受到季節性(xing)因素支撐，市場對數(shu)據(ju)有效(xiao)性(xing)提(ti)出質疑。鍍(du)鋅卷工(gong)業(ye)品(pin)而言，近期陸續(xu)公布的重要(yao)數(shu)據(ju)中性(xing)偏(pian)多。但值(zhi)得注意的是，同(tong)年(nian)十(shi)一月熱(re)鍍(du)鋅卷板價(jia)格工(gong)業(ye)增加值(zhi)和(he)投資增速放緩，進一步印證(zheng)了(le)國內總需(xu)求乏力(li)，工(gong)業(ye)復蘇(su)形(xing)勢(shi)不(bu)容(rong)樂觀(guan)。加上(shang)未來經(jing)濟結(jie)構(gou)調整等因素，工(gong)業(ye)品(pin)價(jia)格反(fan)彈高度(du)將有限。傳統(tong)(tong)需(xu)求淡季效(xiao)應(ying)還在持續(xu)不(bu)斷地發酵，冬儲效(xiao)果不(bu)佳。雖(sui)然數(shu)據(ju)顯(xian)示供應(ying)壓(ya)力(li)開始(shi)減輕，但是目(mu)前處(chu)于鋼鐵需(xu)求淡季，市場成交萎縮，下(xia)游采購遲遲未能有效(xiao)跟進，市場信心(xin)不(bu)足，鍍(du)鋅鋼板貿易商囤貨(huo)現象也不(bu)明顯(xian)。
