電鍍鋅價格鍍鋅鋼板的表面鍍鋅主要采用的方法是熱鍍鋅。德陽電鍍鋅熱(re)(re)鍍(du)(du)(du)(du)(du)鋅(xin)是(shi)由較(jiao)古老的(de)熱(re)(re)鍍(du)(du)(du)(du)(du)方法發展(zhan)而(er)來(lai)的(de)，自從1836年(nian)法國把熱(re)(re)鍍(du)(du)(du)(du)(du)鋅(xin)應用(yong)于(yu)工業以來(lai)，已經(jing)有(you)一百七十(shi)年(nian)的(de)歷(li)史了。然而(er)，熱(re)(re)鍍(du)(du)(du)(du)(du)鋅(xin)工業是(shi)近三十(shi)年(nian)來(lai)伴隨(sui)冷軋帶鋼的(de)飛速發展(zhan)而(er)得到(dao)了大規模(mo)發展(zhan)。鍍(du)(du)(du)(du)(du)鋅(xin)溶(rong)(rong)液(ye)(ye)(ye)有(you)氰(qing)(qing)化物鍍(du)(du)(du)(du)(du)液(ye)(ye)(ye)和無氰(qing)(qing)鍍(du)(du)(du)(du)(du)液(ye)(ye)(ye)兩類。氰(qing)(qing)化物鍍(du)(du)(du)(du)(du)液(ye)(ye)(ye)中分微氰(qing)(qing)、低氰(qing)(qing)、中氰(qing)(qing)、和高氰(qing)(qing)幾(ji)類。無氰(qing)(qing)鍍(du)(du)(du)(du)(du)液(ye)(ye)(ye)有(you)堿性鋅(xin)酸鹽鍍(du)(du)(du)(du)(du)液(ye)(ye)(ye)、銨鹽鍍(du)(du)(du)(du)(du)液(ye)(ye)(ye)、硫酸鹽鍍(du)(du)(du)(du)(du)液(ye)(ye)(ye)及(ji)無氨(an)氯化物鍍(du)(du)(du)(du)(du)液(ye)(ye)(ye)等。氰(qing)(qing)化鍍(du)(du)(du)(du)(du)鋅(xin)溶(rong)(rong)液(ye)(ye)(ye)均(jun)鍍(du)(du)(du)(du)(du)能力(li)好，得到(dao)的(de)鍍(du)(du)(du)(du)(du)層光滑細致(zhi)，在生產中被長期采用(yong)。但(dan)由于(yu)氰(qing)(qing)化物劇(ju)毒(du)，對環(huan)境(jing)污染嚴(yan)重，近年(nian)來(lai)已趨向(xiang)于(yu)采用(yong)低氰(qing)(qing)、微氰(qing)(qing)、無氰(qing)(qing)鍍(du)(du)(du)(du)(du)鋅(xin)溶(rong)(rong)液(ye)(ye)(ye)。

鍍鋅(xin)(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)是為防(fang)止鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)表(biao)面(mian)遭受腐蝕，延長其(qi)(qi)使(shi)(shi)用(yong)壽命，在(zai)(zai)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)表(biao)面(mian)涂(tu)以一(yi)層金(jin)(jin)(jin)屬鋅(xin)(xin)(xin)，這種涂(tu)鋅(xin)(xin)(xin)的(de)薄鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)稱為鍍鋅(xin)(xin)(xin)板(ban)(ban)(ban)(ban)(ban)。鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)也(ye)是用(yong)熱(re)浸(jin)(jin)(jin)法制造，但(dan)在(zai)(zai)出槽(cao)后，立即(ji)把它加(jia)熱(re)到(dao)500℃左右，使(shi)(shi)其(qi)(qi)生成(cheng)鋅(xin)(xin)(xin)和(he)鐵(tie)的(de)合(he)金(jin)(jin)(jin)被膜。這種鍍鋅(xin)(xin)(xin)卷具有良(liang)好的(de)涂(tu)料的(de)密著(zhu)性(xing)和(he)焊接性(xing)。合(he)金(jin)(jin)(jin)化鍍鋅(xin)(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)。這種鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)也(ye)是用(yong)熱(re)浸(jin)(jin)(jin)法制造，但(dan)在(zai)(zai)出槽(cao)后，立即(ji)把它加(jia)熱(re)到(dao)500℃左右，使(shi)(shi)其(qi)(qi)生成(cheng)鋅(xin)(xin)(xin)和(he)鐵(tie)的(de)合(he)金(jin)(jin)(jin)被膜。這種鍍鋅(xin)(xin)(xin)板(ban)(ban)(ban)(ban)(ban)具有良(liang)好的(de)涂(tu)料的(de)密著(zhu)性(xing)和(he)焊接性(xing)。熱(re)浸(jin)(jin)(jin)鍍鋅(xin)(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)。將薄鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)浸(jin)(jin)(jin)入熔解(jie)的(de)鋅(xin)(xin)(xin)槽(cao)中，使(shi)(shi)其(qi)(qi)表(biao)面(mian)粘附一(yi)層鋅(xin)(xin)(xin)的(de)薄鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)。目前主(zhu)要采用(yong)連續鍍鋅(xin)(xin)(xin)工藝生產，即(ji)把成(cheng)卷的(de)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)連續浸(jin)(jin)(jin)在(zai)(zai)熔解(jie)有鋅(xin)(xin)(xin)的(de)鍍槽(cao)中制成(cheng)鍍鋅(xin)(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)。合(he)金(jin)(jin)(jin)、復(fu)合(he)鍍鋅(xin)(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)。它是用(yong)鋅(xin)(xin)(xin)和(he)其(qi)(qi)他金(jin)(jin)(jin)屬如(ru)鉛、鋅(xin)(xin)(xin)制成(cheng)合(he)金(jin)(jin)(jin)乃(nai)至復(fu)合(he)鍍成(cheng)的(de)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)。這種鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)既(ji)具有防(fang)銹性(xing)能，又有良(liang)好的(de)涂(tu)裝性(xing)能。

樓承(cheng)(cheng)(cheng)板(ban)(ban)(ban)(ban)適應主體(ti)(ti)鋼(gang)(gang)(gang)結(jie)構快速施工的(de)(de)(de)要求，能(neng)夠在短時(shi)間內提供(gong)堅定的(de)(de)(de)作業平臺，并可(ke)(ke)采用(yong)多個樓層(ceng)鋪設壓型(xing)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)，分層(ceng)澆(jiao)筑(zhu)混凝土板(ban)(ban)(ban)(ban)的(de)(de)(de)流(liu)水施工。在使用(yong)階(jie)段樓承(cheng)(cheng)(cheng)板(ban)(ban)(ban)(ban)作為(wei)混凝土樓板(ban)(ban)(ban)(ban)的(de)(de)(de)受(shou)拉(la)鋼(gang)(gang)(gang)筋(jin)，也提高了樓板(ban)(ban)(ban)(ban)的(de)(de)(de)剛度(du)(du)，節省了鋼(gang)(gang)(gang)筋(jin)和混凝土的(de)(de)(de)用(yong)量。樓承(cheng)(cheng)(cheng)板(ban)(ban)(ban)(ban)上面(mian)(mian)可(ke)(ke)以鋪設保溫，隔音，隔熱(re)，隔振(zhen)等材(cai)料(liao)。樓面(mian)(mian)性能(neng)充分發揮鋼(gang)(gang)(gang)的(de)(de)(de)良(liang)好的(de)(de)(de)抗拉(la)強(qiang)(qiang)度(du)(du)和延性及混凝土優良(liang)的(de)(de)(de)抗壓強(qiang)(qiang)度(du)(du)和較(jiao)大(da)的(de)(de)(de)剛度(du)(du)。壓型(xing)板(ban)(ban)(ban)(ban)表面(mian)(mian)壓紋使樓承(cheng)(cheng)(cheng)板(ban)(ban)(ban)(ban)與混凝土之間產生大(da)的(de)(de)(de)結(jie)合力，使二者形(xing)成整體(ti)(ti)，配(pei)以加勁(jing)肋，使樓承(cheng)(cheng)(cheng)板(ban)(ban)(ban)(ban)系統具有高強(qiang)(qiang)承(cheng)(cheng)(cheng)載力。在懸(xuan)臂(bei)條件下，樓承(cheng)(cheng)(cheng)板(ban)(ban)(ban)(ban)僅作為(wei)性模板(ban)(ban)(ban)(ban)。懸(xuan)挑的(de)(de)(de)長度(du)(du)可(ke)(ke)根(gen)據樓承(cheng)(cheng)(cheng)板(ban)(ban)(ban)(ban)的(de)(de)(de)截面(mian)(mian)特性來(lai)定。為(wei)了防止懸(xuan)挑板(ban)(ban)(ban)(ban)的(de)(de)(de)開(kai)裂，需(xu)在支座處(chu)依結(jie)構工程師的(de)(de)(de)設計配(pei)上負(fu)筋(jin)。

鍍鋅(xin)(xin)(xin)帶(dai)鋼(gang)的鋅(xin)(xin)(xin)層特性(xing) 電鍍鋅(xin)(xin)(xin)層是(shi)不能形成鋅(xin)(xin)(xin)花(hua)(hua)的，熱鍍鋅(xin)(xin)(xin)層則有鋅(xin)(xin)(xin)花(hua)(hua)，其(qi)形成過程(cheng)如下：當鍍鋅(xin)(xin)(xin)帶(dai)從(cong)(cong)鋅(xin)(xin)(xin)鍋出來(lai)后，經氣(qi)刀(dao)的噴吹(chui)，大(da)(da)量(liang)鋅(xin)(xin)(xin)液被吹(chui)回鋅(xin)(xin)(xin)鍋，這時帶(dai)鋼(gang)表面還有純鋅(xin)(xin)(xin)層，呈液 態附在(zai)鋼(gang)板(ban)表面，在(zai)鋼(gang)板(ban)表面形成大(da)(da)量(liang)結晶核，隨(sui)(sui)著鋼(gang)板(ban)上升冷(leng)卻，使結晶核慢(man)(man)慢(man)(man)長成鋅(xin)(xin)(xin)花(hua)(hua)。冷(leng)卻速度越快鋅(xin)(xin)(xin)花(hua)(hua)越小，冷(leng)卻速度越慢(man)(man)鋅(xin)(xin)(xin)花(hua)(hua)越大(da)(da)。熱鍍鋅(xin)(xin)(xin)帶(dai)鋼(gang)在(zai)我(wo)國市場一直是(shi)緊缺(que)品種。從(cong)(cong)20世紀90年代(dai)中期以來(lai)，每年都要從(cong)(cong)國外(wai)進口80-100萬t左右。隨(sui)(sui)著國內經濟(ji)的發展，尤其(qi)是(shi)汽車、家電及建筑業的發展，對(dui)鍍鋅(xin)(xin)(xin)帶(dai)鋼(gang)的需求量(liang)也大(da)(da)大(da)(da)增加。

熱(re)(re)鍍(du)鋅(xin)卷(juan)板(ban)(ban)現貨消息：熱(re)(re)鍍(du)鋅(xin)產(chan)(chan)品廣泛用(yong)于建筑(zhu)、家(jia)電(dian)、車船、容器制造業、機電(dian)業等，幾乎涉及到衣食(shi)住行各個領域。近年來，世界鍍(du)鋅(xin)鋼板(ban)(ban)需求量不斷增加，產(chan)(chan)量增長也很快，在(zai)美、日等鋼材(cai)生產(chan)(chan)大國，熱(re)(re)鍍(du)鋅(xin)鋼板(ban)(ban)在(zai)鋼材(cai)中所占比例已(yi)(yi)高達13%-15%。 熱(re)(re)鍍(du)鋅(xin)卷(juan)板(ban)(ban)現貨消息：近來，汽車行業越來越重(zhong)視材(cai)料的(de)使用(yong)壽(shou)命，用(yong)涂漆冷軋鋼板(ban)(ban)已(yi)(yi)不能滿足耐腐蝕(shi)方面的(de)要求。在(zai)這(zhe)種情況(kuang)下，耐腐蝕(shi)性(xing)優良且(qie)成本低廉的(de)熱(re)(re)鍍(du)鋅(xin)板(ban)(ban)開(kai)始(shi)普遍受到了汽車廠家(jia)的(de)青睞。
