鍍(du)(du)(du)鋅(xin)(xin)板(ban)(ban)選擇(ze)(ze)要(yao)注(zhu)(zhu)(zhu)重(zhong)(zhong)的(de)(de)(de)(de)幾個要(yao)點，工業(ye)企業(ye)的(de)(de)(de)(de)客戶選擇(ze)(ze)專用工業(ye)原料，要(yao)注(zhu)(zhu)(zhu)重(zhong)(zhong)從(cong)四個標準(zhun)。一是(shi)(shi)(shi)要(yao)注(zhu)(zhu)(zhu)重(zhong)(zhong)品(pin)(pin)牌來(lai)進(jin)行選擇(ze)(ze)，因為鍍(du)(du)(du)鋅(xin)(xin)技(ji)術的(de)(de)(de)(de)要(yao)求嚴格(ge)，所(suo)以有(you)的(de)(de)(de)(de)基礎，當然產品(pin)(pin)質(zhi)量(liang)與(yu)技(ji)術標準(zhun)都會更可靠，都會有(you)好(hao)的(de)(de)(de)(de)專業(ye)標準(zhun)。二(er)(er)是(shi)(shi)(shi)要(yao)注(zhu)(zhu)(zhu)重(zhong)(zhong)產品(pin)(pin)本(ben)身的(de)(de)(de)(de)鍍(du)(du)(du)層質(zhi)量(liang)，鍍(du)(du)(du)層一要(yao)靠技(ji)術，二(er)(er)要(yao)靠純度，所(suo)以從(cong)產品(pin)(pin)表(biao)面來(lai)看質(zhi)量(liang)，這(zhe)是(shi)(shi)(shi)基本(ben)也是(shi)(shi)(shi)重(zhong)(zhong)要(yao)的(de)(de)(de)(de)一個標準(zhun)。三是(shi)(shi)(shi)要(yao)看基礎材(cai)料。鍍(du)(du)(du)鋅(xin)(xin)板(ban)(ban)基礎金(jin)屬材(cai)料的(de)(de)(de)(de)質(zhi)量(liang)，與(yu)成品(pin)(pin)鍍(du)(du)(du)鋅(xin)(xin)板(ban)(ban)的(de)(de)(de)(de)質(zhi)量(liang)與(yu)耐(nai)用性密切相關，所(suo)以在進(jin)行產品(pin)(pin)選擇(ze)(ze)的(de)(de)(de)(de)時候，需要(yao)注(zhu)(zhu)(zhu)重(zhong)(zhong)這(zhe)個細節，而材(cai)料的(de)(de)(de)(de)提供，就是(shi)(shi)(shi)對于工業(ye)生產來(lai)說，有(you)基礎條件(jian)。四是(shi)(shi)(shi)要(yao)注(zhu)(zhu)(zhu)重(zhong)(zhong)價(jia)格(ge)對比，不是(shi)(shi)(shi)好(hao)的(de)(de)(de)(de)就是(shi)(shi)(shi)貴的(de)(de)(de)(de)，但是(shi)(shi)(shi)如果廉價(jia)的(de)(de)(de)(de)把產品(pin)(pin)，那是(shi)(shi)(shi)不可信的(de)(de)(de)(de)。

熱(re)鍍(du)鋅生(sheng)產發展(zhan)一直處于滯后(hou)狀(zhuang)態(tai)。20世紀50年代(dai)到60年代(dai)陸續(xu)建成了13條單張鋼板熔劑法熱(re)鍍(du)鋅機(ji)(ji)組(zu)(zu)，能力為10萬(wan)t/a，但因產量(liang)(liang)低(di)、成本高(gao)、質(zhi)量(liang)(liang)差、污染環境、經(jing)(jing)濟效益差等(deng)缺陷已先后(hou)停(ting)、轉產。從(cong)(cong)20世紀70年代(dai)末，我國才開(kai)始建造大型(xing)寬帶(dai)熱(re)鍍(du)鋅機(ji)(ji)組(zu)(zu)。熱(re)鍍(du)鋅帶(dai)鋼在(zai)我國市場(chang)一直是緊(jin)缺品種。從(cong)(cong)20世紀90年代(dai)中期以(yi)來(lai)，每年都要從(cong)(cong)國外進口80-100萬(wan)t左右(you)。隨著國內經(jing)(jing)濟的(de)(de)發展(zhan)，尤其是汽車、家電(dian)及建筑(zhu)業的(de)(de)發展(zhan)，對鍍(du)鋅帶(dai)鋼的(de)(de)需求量(liang)(liang)也大大增加。

鍍(du)鋅(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)(ban)是為防止鋼(gang)(gang)板(ban)(ban)(ban)(ban)表(biao)面(mian)遭受腐蝕(shi)，延長其使用(yong)(yong)壽命，在鋼(gang)(gang)板(ban)(ban)(ban)(ban)表(biao)面(mian)涂(tu)(tu)以(yi)一層金(jin)屬(shu)鋅(xin)(xin)，這種涂(tu)(tu)鋅(xin)(xin)的(de)(de)(de)薄(bo)鋼(gang)(gang)板(ban)(ban)(ban)(ban)稱為鍍(du)鋅(xin)(xin)板(ban)(ban)(ban)(ban)。按生產(chan)及加工方法可分為以(yi)下幾類：熱浸(jin)鍍(du)鋅(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)(ban)。將薄(bo)鋼(gang)(gang)板(ban)(ban)(ban)(ban)浸(jin)入熔(rong) 微商貨源解(jie)的(de)(de)(de)鋅(xin)(xin)槽(cao)(cao)中，使其表(biao)面(mian)粘附(fu)一層鋅(xin)(xin)的(de)(de)(de)薄(bo)鋼(gang)(gang)板(ban)(ban)(ban)(ban)。目前主(zhu)要采用(yong)(yong)連(lian)續鍍(du)鋅(xin)(xin)工藝(yi)生產(chan)，即把(ba)成卷(juan)的(de)(de)(de)鋼(gang)(gang)板(ban)(ban)(ban)(ban)連(lian)續浸(jin)在熔(rong)解(jie)有(you)鋅(xin)(xin)的(de)(de)(de)鍍(du)槽(cao)(cao)中制成鍍(du)鋅(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)(ban)；合金(jin)化鍍(du)鋅(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)(ban)。這種鋼(gang)(gang)板(ban)(ban)(ban)(ban)也是用(yong)(yong)熱浸(jin)法制造(zao)，但在出槽(cao)(cao)后，立即把(ba)它加熱到５００℃左右，使其生成鋅(xin)(xin)和鐵的(de)(de)(de)合金(jin)被膜。這種鍍(du)鋅(xin)(xin)板(ban)(ban)(ban)(ban)具有(you)良(liang)好的(de)(de)(de)涂(tu)(tu)料的(de)(de)(de)密著性(xing)(xing)和焊接性(xing)(xing)。

鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)按用(yong)(yong)途又可(ke)分為(wei)一(yi)般(ban)用(yong)(yong)、屋頂(ding)用(yong)(yong)、建筑外(wai)側板(ban)用(yong)(yong)、結(jie)(jie)構用(yong)(yong)、瓦壟板(ban)用(yong)(yong)、拉伸用(yong)(yong)和(he)深沖(chong)用(yong)(yong)等鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)。對于一(yi)般(ban)防(fang)保(bao)護(hu)用(yong)(yong)鍍(du)(du)(du)(du)層(ceng)，可(ke)以采用(yong)(yong)堿性(xing)鋅(xin)(xin)(xin)(xin)酸鹽鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)彩色(se)鈍化(hua)工(gong)藝。有時(shi)為(wei)了產品的(de)(de)配色(se)需(xu)要，也可(ke)以采用(yong)(yong)藍白色(se)鈍化(hua)工(gong)藝，比如軍綠色(se)鈍化(hua)、黑(hei)色(se)鈍化(hua)等。為(wei)提高鋼(gang)管(guan)(guan)的(de)(de)耐腐(fu)(fu)(fu)蝕(shi)性(xing)能(neng)，對一(yi)般(ban)鋼(gang)管(guan)(guan)進行鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)。鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)卷分熱鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)和(he)電(dian)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)兩種，熱鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)層(ceng)厚，電(dian)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)成(cheng)本低，表面不是很光(guang)滑。吹氧焊管(guan)(guan)：用(yong)(yong)作(zuo)煉鋼(gang)吹氧用(yong)(yong)管(guan)(guan)，一(yi)般(ban)用(yong)(yong)小口(kou)徑的(de)(de)焊接鋼(gang)管(guan)(guan)，規格(ge)由(you)3/8-2寸(cun)八種。用(yong)(yong)08、10、15、20或者195-Q235的(de)(de)鋼(gang)帶制(zhi)作(zuo)成(cheng)的(de)(de)，為(wei)了防(fang)腐(fu)(fu)(fu)蝕(shi)，有得進行滲鋁處理。鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)其(qi)防(fang)護(hu)作(zuo)用(yong)(yong)更強(qiang)，抗腐(fu)(fu)(fu)蝕(shi)能(neng)力強(qiang)。整個結(jie)(jie)構由(you)鋅(xin)(xin)(xin)(xin)，形(xing)成(cheng)致密的(de)(de)四元結(jie)(jie)晶(jing)體，此結(jie)(jie)晶(jing)體在鋼(gang)板(ban)上形(xing)成(cheng)一(yi)層(ceng)屏(ping)障， 因而有效(xiao)的(de)(de)防(fang)止腐(fu)(fu)(fu)蝕(shi)因子穿透。 耐腐(fu)(fu)(fu)蝕(shi)性(xing)來(lai)自鋅(xin)(xin)(xin)(xin)的(de)(de)障礙層(ceng)保(bao)護(hu)功能(neng)強(qiang)。

閬中鍍鋅鋼板近期鋼價延續低迷，隨著通國規模的酷暑和旱季到來，熱鍍鋅卷板價格商場逐漸進入需要旺季，海內鋼鐵商場或將窄幅調整。在決策層兩手抓制度措施落實狀況、貨銀本位度定向寬松力度加大的直觀層面利好牽動下，商場信念逐漸趨穩，短期海內鋼價無望止跌企穩;另一上面，以后鋼價殺跌電能有余，而上漲也仍然屏障重重。鍍鋅鋼板廠家熱鍍鋅卷(juan)板價格價錢(qian)或將(jiang)長期在于低位運行場面。
