鍍(du)(du)鋅(xin)鋼板的(de)表面鍍(du)(du)鋅(xin)主要采(cai)(cai)(cai)用的(de)方法(fa)是熱(re)(re)鍍(du)(du)鋅(xin)。熱(re)(re)鍍(du)(du)鋅(xin)是由(you)較古老的(de)熱(re)(re)鍍(du)(du)方法(fa)發展而(er)(er)來(lai)的(de)，自從(cong)1836年(nian)法(fa)國把(ba)熱(re)(re)鍍(du)(du)鋅(xin)應用于工業以來(lai)，已經(jing)有(you)(you)一百七(qi)十年(nian)的(de)歷史了。然(ran)而(er)(er)，熱(re)(re)鍍(du)(du)鋅(xin)工業是近三十年(nian)來(lai)伴隨(sui)冷(leng)軋帶鋼的(de)飛速(su)發展而(er)(er)得(de)到(dao)了大規模發展。鍍(du)(du)鋅(xin)溶(rong)液有(you)(you)氰(qing)(qing)化(hua)物鍍(du)(du)液和(he)無氰(qing)(qing)鍍(du)(du)液兩類(lei)。氰(qing)(qing)化(hua)物鍍(du)(du)液中(zhong)分(fen)微氰(qing)(qing)、低氰(qing)(qing)、中(zhong)氰(qing)(qing)、和(he)高氰(qing)(qing)幾類(lei)。無氰(qing)(qing)鍍(du)(du)液有(you)(you)堿性鋅(xin)酸(suan)鹽鍍(du)(du)液、銨鹽鍍(du)(du)液、硫酸(suan)鹽鍍(du)(du)液及無氨(an)氯(lv)化(hua)物鍍(du)(du)液等。氰(qing)(qing)化(hua)鍍(du)(du)鋅(xin)溶(rong)液均鍍(du)(du)能力好，得(de)到(dao)的(de)鍍(du)(du)層光(guang)滑細致，在生產中(zhong)被長期采(cai)(cai)(cai)用。但由(you)于氰(qing)(qing)化(hua)物劇(ju)毒(du)，對環境污(wu)染嚴重，近年(nian)來(lai)已趨向于采(cai)(cai)(cai)用低氰(qing)(qing)、微氰(qing)(qing)、無氰(qing)(qing)鍍(du)(du)鋅(xin)溶(rong)液。

重慶鍍(du)鋅(xin)(xin)(xin)板(ban)(ban)按生產(chan)及加工方法可分為(wei)以(yi)下幾類： 熱浸(jin)鍍(du)鋅(xin)(xin)(xin)鋼(gang)板(ban)(ban)。將薄(bo)(bo)(bo)鋼(gang)板(ban)(ban)浸(jin)入熔解(jie)的(de)(de)(de)鋅(xin)(xin)(xin)槽中(zhong)，使(shi)其表(biao)面(mian)粘附一層(ceng)鋅(xin)(xin)(xin)的(de)(de)(de)薄(bo)(bo)(bo)鋼(gang)板(ban)(ban)。目前(qian)主要采用(yong)連續鍍(du)鋅(xin)(xin)(xin)工藝生產(chan)，即把成卷的(de)(de)(de)鋼(gang)板(ban)(ban)連續浸(jin)在(zai)(zai)熔解(jie)有(you)(you)鋅(xin)(xin)(xin)的(de)(de)(de)鍍(du)槽中(zhong)制成鍍(du)鋅(xin)(xin)(xin)鋼(gang)板(ban)(ban)； 合(he)(he)金(jin)化鍍(du)鋅(xin)(xin)(xin)鋼(gang)板(ban)(ban)。為(wei)克服單面(mian)未涂鋅(xin)(xin)(xin)的(de)(de)(de)缺點，又(you)有(you)(you)一種在(zai)(zai)另面(mian)涂以(yi)薄(bo)(bo)(bo)層(ceng)鋅(xin)(xin)(xin)的(de)(de)(de)鍍(du)鋅(xin)(xin)(xin)板(ban)(ban)，即雙面(mian)差鍍(du)鋅(xin)(xin)(xin)板(ban)(ban)；合(he)(he)金(jin)、復(fu)合(he)(he)鍍(du)鋅(xin)(xin)(xin)鋼(gang)板(ban)(ban)。它是用(yong)鋅(xin)(xin)(xin)和其他金(jin)屬(shu)如(ru)鉛、鋅(xin)(xin)(xin)制成合(he)(he)金(jin)乃至(zhi)復(fu)合(he)(he)鍍(du)成的(de)(de)(de)鋼(gang)板(ban)(ban)。這(zhe)種鋼(gang)板(ban)(ban)既具(ju)有(you)(you)防銹性能，又(you)有(you)(you)良好(hao)的(de)(de)(de)涂裝性能。

樓(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)(ban)(ban)適應主體(ti)鋼(gang)(gang)結構快速(su)施工(gong)的(de)(de)要(yao)求(qiu)，能夠(gou)在短時(shi)間內提供堅定(ding)的(de)(de)作業平臺，并(bing)可(ke)(ke)采用多個樓(lou)層(ceng)鋪(pu)設壓(ya)型鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)(ban)，分層(ceng)澆筑(zhu)混(hun)(hun)凝(ning)土(tu)(tu)板(ban)(ban)(ban)(ban)(ban)(ban)的(de)(de)流水施工(gong)。在使(shi)(shi)用階段樓(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)(ban)(ban)作為混(hun)(hun)凝(ning)土(tu)(tu)樓(lou)板(ban)(ban)(ban)(ban)(ban)(ban)的(de)(de)受拉(la)鋼(gang)(gang)筋，也(ye)提高了樓(lou)板(ban)(ban)(ban)(ban)(ban)(ban)的(de)(de)剛(gang)度，節省了鋼(gang)(gang)筋和混(hun)(hun)凝(ning)土(tu)(tu)的(de)(de)用量。樓(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)(ban)(ban)上面可(ke)(ke)以(yi)鋪(pu)設保溫，隔(ge)音(yin)，隔(ge)熱，隔(ge)振等材料。樓(lou)面性(xing)(xing)能充分發揮鋼(gang)(gang)的(de)(de)良(liang)好的(de)(de)抗(kang)拉(la)強度和延性(xing)(xing)及(ji)混(hun)(hun)凝(ning)土(tu)(tu)優良(liang)的(de)(de)抗(kang)壓(ya)強度和較大的(de)(de)剛(gang)度。壓(ya)型板(ban)(ban)(ban)(ban)(ban)(ban)表面壓(ya)紋(wen)使(shi)(shi)樓(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)(ban)(ban)與混(hun)(hun)凝(ning)土(tu)(tu)之間產生大的(de)(de)結合力，使(shi)(shi)二者形成整體(ti)，配以(yi)加(jia)勁肋，使(shi)(shi)樓(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)(ban)(ban)系統具有高強承(cheng)(cheng)載(zai)力。在懸(xuan)臂條件下，樓(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)(ban)(ban)僅作為性(xing)(xing)模板(ban)(ban)(ban)(ban)(ban)(ban)。懸(xuan)挑(tiao)的(de)(de)長度可(ke)(ke)根據樓(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)(ban)(ban)的(de)(de)截(jie)面特性(xing)(xing)來定(ding)。為了防止懸(xuan)挑(tiao)板(ban)(ban)(ban)(ban)(ban)(ban)的(de)(de)開(kai)裂(lie)，需在支(zhi)座處依結構工(gong)程師的(de)(de)設計(ji)配上負筋。

昆山酒鋼電鍍鋅要看整個樓板的厚度來考慮挑選是用75波高系列的仍是51波高系列的，沉默有40系列，46系列，60系列，65波高系列。電鍍鋅批發一(yi)般(ban)來說波高(gao)(gao)越低，承(cheng)(cheng)載力就越低，然(ran)后就是波峰距離越大，承(cheng)(cheng)載力就越小，假如整個樓(lou)(lou)板(ban)厚(hou)(hou)度(du)在10公分(fen)以內，好選(xuan)用(yong)選(xuan)用(yong)波高(gao)(gao)40系列(lie)，整個樓(lou)(lou)板(ban)厚(hou)(hou)度(du)在10-13公分(fen)以內，好選(xuan)用(yong)50波高(gao)(gao)系列(lie)，在13公分(fen)以上，好選(xuan)用(yong)75系列(lie)。有些人會問，為什么呀(ya)?其(qi)實《我國(guo)鋼筋(jin)混(hun)凝土修(xiu)建規范》里有個要求，鋼筋(jin)上面的(de)混(hun)泥(ni)土保護(hu)層不能低于2.5cm，就是說樓(lou)(lou)承(cheng)(cheng)板(ban)自身的(de)波高(gao)(gao)+鋼筋(jin)網的(de)厚(hou)(hou)度(du)(一(yi)般(ban)2cm)+2.5cm的(de)保護(hu)層≤樓(lou)(lou)板(ban)的(de)厚(hou)(hou)度(du)。

熱(re)浸鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)將薄鋼(gang)板(ban)(ban)(ban)(ban)(ban)浸入熔解的鋅(xin)(xin)槽(cao)(cao)中，使(shi)其表面(mian)(mian)粘附一層鋅(xin)(xin)的薄鋼(gang)板(ban)(ban)(ban)(ban)(ban)。目前主要采用連續鍍(du)(du)(du)鋅(xin)(xin)工藝生產，即把成卷的鋼(gang)板(ban)(ban)(ban)(ban)(ban)連續浸在(zai)熔解有鋅(xin)(xin)的鍍(du)(du)(du)槽(cao)(cao)中制成鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban);合(he)金(jin)(jin)化鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)。這種鋼(gang)板(ban)(ban)(ban)(ban)(ban)也是用熱(re)浸法制造，但在(zai)出(chu)槽(cao)(cao)后(hou)，立即把它加(jia)熱(re)到500 ℃左右，使(shi)其生成鋅(xin)(xin)和(he)鐵的合(he)金(jin)(jin)被膜。這種鍍(du)(du)(du)鋅(xin)(xin)板(ban)(ban)(ban)(ban)(ban)具(ju)有良好(hao)的涂(tu)料的密著(zhu)性(xing)和(he)焊接性(xing);電鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)。用電鍍(du)(du)(du)法制造這種鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)具(ju)有良好(hao)的加(jia)工性(xing)。但鍍(du)(du)(du)層較(jiao)薄，耐腐蝕性(xing)不如熱(re)浸法鍍(du)(du)(du)鋅(xin)(xin)板(ban)(ban)(ban)(ban)(ban);單面(mian)(mian)鍍(du)(du)(du)和(he)雙(shuang)面(mian)(mian)差鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)。單面(mian)(mian)鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)，即只在(zai)一面(mian)(mian)鍍(du)(du)(du)鋅(xin)(xin)的產品。在(zai)焊接、涂(tu)裝、防銹處理、加(jia)工等方面(mian)(mian)，具(ju)有比雙(shuang)面(mian)(mian)鍍(du)(du)(du)鋅(xin)(xin)板(ban)(ban)(ban)(ban)(ban)好(hao)的適(shi)應性(xing)。
