鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)卷分熱鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)和電鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)兩(liang)種，熱鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)層(ceng)厚，具(ju)有(you)鍍(du)(du)(du)(du)層(ceng)均勻，附著(zhu)力(li)強，使用壽命長等優(you)點。電鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)成本(ben)低(di)，表(biao)面不是很(hen)光滑，其本(ben)身的(de)耐(nai)腐蝕(shi)(shi)性(xing)比熱鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)管相差很(hen)多。提起鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)管，可能沒接觸(chu)過建材的(de)朋(peng)友并不了(le)解。從1935年建立一條連續涂(tu)(tu)(tu)層(ceng)鋼板(ban)線開始，彩(cai)涂(tu)(tu)(tu)板(ban)得到(dao)了(le)廣泛應用，目前彩(cai)涂(tu)(tu)(tu)板(ban)的(de)品種繁多，大(da)約(yue)超過600種，彩(cai)涂(tu)(tu)(tu)板(ban)兼有(you)機聚合(he)(he)物(wu)與鋼板(ban)兩(liang)者的(de)優(you)點，既有(you)有(you)機聚合(he)(he)物(wu)的(de)良好(hao)著(zhu)色性(xing)、成型性(xing)、耐(nai)蝕(shi)(shi)性(xing)、裝(zhuang)飾(shi)性(xing)、又有(you)鋼板(ban)的(de)高強度和易(yi)加(jia)工(gong)性(xing)，能很(hen)容易(yi)地進行沖壓裁(cai)剪、彎曲、深沖等加(jia)工(gong)。

鍍(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)(gang)(gang)(gang)(gang)板按用(yong)(yong)(yong)(yong)途又可分為一(yi)般(ban)(ban)用(yong)(yong)(yong)(yong)、屋頂用(yong)(yong)(yong)(yong)、建筑外側板用(yong)(yong)(yong)(yong)、結構用(yong)(yong)(yong)(yong)、瓦壟板用(yong)(yong)(yong)(yong)、拉(la)伸用(yong)(yong)(yong)(yong)和深(shen)沖用(yong)(yong)(yong)(yong)等(deng)鍍(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)(gang)(gang)(gang)(gang)板。對于一(yi)般(ban)(ban)防(fang)(fang)保護用(yong)(yong)(yong)(yong)鍍(du)(du)(du)層，可以采用(yong)(yong)(yong)(yong)堿性(xing)鋅(xin)(xin)(xin)酸鹽(yan)鍍(du)(du)(du)鋅(xin)(xin)(xin)彩色(se)鈍化(hua)(hua)工(gong)藝(yi)。有時為了產品的配色(se)需要，也可以采用(yong)(yong)(yong)(yong)藍白(bai)色(se)鈍化(hua)(hua)工(gong)藝(yi)，比(bi)如軍綠色(se)鈍化(hua)(hua)、黑色(se)鈍化(hua)(hua)等(deng)。為提高(gao)鋼(gang)(gang)(gang)(gang)(gang)管的耐腐(fu)蝕性(xing)能，對一(yi)般(ban)(ban)鋼(gang)(gang)(gang)(gang)(gang)管進行鍍(du)(du)(du)鋅(xin)(xin)(xin)。鍍(du)(du)(du)鋅(xin)(xin)(xin)卷分熱鍍(du)(du)(du)鋅(xin)(xin)(xin)和電鍍(du)(du)(du)鋅(xin)(xin)(xin)兩種(zhong)，熱鍍(du)(du)(du)鋅(xin)(xin)(xin)鍍(du)(du)(du)鋅(xin)(xin)(xin)層厚(hou)，電鍍(du)(du)(du)鋅(xin)(xin)(xin)成(cheng)本(ben)低(di)，表面(mian)不是很(hen)光滑(hua)。吹(chui)氧焊(han)管：用(yong)(yong)(yong)(yong)作煉鋼(gang)(gang)(gang)(gang)(gang)吹(chui)氧用(yong)(yong)(yong)(yong)管，一(yi)般(ban)(ban)用(yong)(yong)(yong)(yong)小口徑的焊(han)接(jie)鋼(gang)(gang)(gang)(gang)(gang)管，規格由3/8-2寸(cun)八種(zhong)。用(yong)(yong)(yong)(yong)08、10、15、20或者(zhe)195-Q235的鋼(gang)(gang)(gang)(gang)(gang)帶(dai)制作成(cheng)的，為了防(fang)(fang)腐(fu)蝕，有得進行滲鋁處理。鍍(du)(du)(du)鋅(xin)(xin)(xin)其(qi)防(fang)(fang)護作用(yong)(yong)(yong)(yong)更強，抗腐(fu)蝕能力強。整個結構由鋅(xin)(xin)(xin)，形(xing)(xing)成(cheng)致(zhi)密的四元結晶體(ti)，此結晶體(ti)在鋼(gang)(gang)(gang)(gang)(gang)板上形(xing)(xing)成(cheng)一(yi)層屏(ping)障(zhang)， 因(yin)而有效的防(fang)(fang)止腐(fu)蝕因(yin)子穿(chuan)透。 耐腐(fu)蝕性(xing)來自鋅(xin)(xin)(xin)的障(zhang)礙(ai)層保護功能強。

熱鍍鋅(xin)生產(chan)發(fa)展一(yi)直(zhi)處于(yu)滯(zhi)后(hou)狀態。20世紀(ji)50年(nian)代到60年(nian)代陸(lu)續建(jian)成了13條單張鋼(gang)板熔劑法熱鍍鋅(xin)機(ji)組(zu)，能力(li)為10萬t/a，但因產(chan)量低(di)、成本高、質(zhi)量差(cha)、污染環(huan)境、經濟(ji)效(xiao)益差(cha)等缺(que)陷已先后(hou)停、轉產(chan)。從20世紀(ji)70年(nian)代末，我國才(cai)開始建(jian)造大型寬帶(dai)熱鍍鋅(xin)機(ji)組(zu)。熱鍍鋅(xin)帶(dai)鋼(gang)在我國市場一(yi)直(zhi)是緊缺(que)品種(zhong)。從20世紀(ji)90年(nian)代中期以來，每年(nian)都(dou)要從國外進口(kou)80-100萬t左右。隨著國內(nei)經濟(ji)的(de)發(fa)展，尤(you)其是汽車、家電及(ji)建(jian)筑(zhu)業(ye)的(de)發(fa)展，對鍍鋅(xin)帶(dai)鋼(gang)的(de)需求量也(ye)大大增加。

彭州攀華冷軋板從整體生產方面來看，人們能夠意識到鍍鋅板在生產過程中應用范圍是很大的，而各位朋友也應該認識該種產品未來發展的情況，只有這樣才能夠對產品有更為掌握。所以希望生活中每一位朋友都能夠認知這部分的內容，這樣在每個部分才能夠獲取好的答案。冷軋板廠家鍍鋅板生(sheng)(sheng)產(chan)(chan)方(fang)面國內(nei)存在著(zhu)供應(ying)不(bu)足的(de)問(wen)題(ti)，所以市場方(fang)面應(ying)該加(jia)強生(sheng)(sheng)產(chan)(chan)，而在生(sheng)(sheng)產(chan)(chan)技術方(fang)面的(de)提升也是很重要(yao)(yao)(yao)的(de)。只(zhi)有能夠以更加(jia)認真的(de)態度(du)掌握這(zhe)部分(fen)的(de)內(nei)容(rong)，這(zhe)樣(yang)整體生(sheng)(sheng)產(chan)(chan)才能夠更加(jia)順利。自然進口也是很重要(yao)(yao)(yao)的(de)一部分(fen)，不(bu)過(guo)進口產(chan)(chan)品在價格方(fang)面也存在著(zhu)更高方(fang)面的(de)問(wen)題(ti)，所以國內(nei)生(sheng)(sheng)產(chan)(chan)加(jia)強是很重要(yao)(yao)(yao)的(de)。
