蘇州攀華鍍鋁鋅板隨著鋼結構在建筑材料中的興起,越來越多的人選擇使用鋼結構樓承板了,鋼結構構件工廠產業化生產大大縮短了工程工期,而樓板的施工方法卻成為影響工期的重要因素。采用那一代樓承板對于樓板的耐火性能也有區別。鍍鋁鋅板廠家樓(lou)承(cheng)(cheng)板的(de)(de)厚度(du)(du)(du)一般都是(shi)按保險起(qi)見(jian)設計的(de)(de)比(bi)較厚,正(zheng)常情況下鋼(gang)梁之間的(de)(de)跨度(du)(du)(du)在2m以(yi)(yi)內樓(lou)承(cheng)(cheng)板厚度(du)(du)(du)在0.75-0.8mm就(jiu)可以(yi)(yi)了,2-2.5m樓(lou)承(cheng)(cheng)板厚度(du)(du)(du)用(yong)0.8-1.0就(jiu)可以(yi)(yi)了,跨度(du)(du)(du)在3-4米(mi)樓(lou)承(cheng)(cheng)板厚度(du)(du)(du)用(yong)1.5mm,超過5m的(de)(de)跨度(du)(du)(du)是(shi)用(yong)臨時支撐,因素就(jiu)是(shi)混泥(ni)土澆筑(zhu)的(de)(de)高度(du)(du)(du),混泥(ni)土澆筑(zhu)的(de)(de)越(yue)(yue)(yue)高,樓(lou)承(cheng)(cheng)板所需(xu)要的(de)(de)厚度(du)(du)(du)也(ye)(ye)就(jiu)越(yue)(yue)(yue)厚,還有一個(ge)大家容易忽略(lve)的(de)(de)因素就(jiu)是(shi)螺釘的(de)(de)好(hao)壞也(ye)(ye)是(shi)決定樓(lou)承(cheng)(cheng)板厚度(du)(du)(du)的(de)(de),螺釘越(yue)(yue)(yue)好(hao)樓(lou)承(cheng)(cheng)板的(de)(de)承(cheng)(cheng)載(zai)力就(jiu)越(yue)(yue)(yue)強。
熱(re)浸(jin)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)將薄鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)浸(jin)入熔(rong)解(jie)的(de)鋅(xin)(xin)(xin)(xin)槽中,使其表(biao)面(mian)粘附一層鋅(xin)(xin)(xin)(xin)的(de)薄鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)。目前主要采用(yong)連續(xu)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)工藝(yi)生產(chan),即(ji)把成卷的(de)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)連續(xu)浸(jin)在(zai)熔(rong)解(jie)有(you)鋅(xin)(xin)(xin)(xin)的(de)鍍(du)(du)(du)(du)(du)槽中制成鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban);合金(jin)化(hua)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)。這(zhe)種(zhong)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)也是用(yong)熱(re)浸(jin)法(fa)制造(zao)(zao),但(dan)在(zai)出槽后(hou),立即(ji)把它(ta)加熱(re)到500 ℃左(zuo)右(you),使其生成鋅(xin)(xin)(xin)(xin)和鐵的(de)合金(jin)被膜。這(zhe)種(zhong)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)具有(you)良好的(de)涂料的(de)密著(zhu)性(xing)和焊(han)接(jie)性(xing);電鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)。用(yong)電鍍(du)(du)(du)(du)(du)法(fa)制造(zao)(zao)這(zhe)種(zhong)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)具有(you)良好的(de)加工性(xing)。但(dan)鍍(du)(du)(du)(du)(du)層較(jiao)薄,耐腐蝕性(xing)不如熱(re)浸(jin)法(fa)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban);單(dan)面(mian)鍍(du)(du)(du)(du)(du)和雙面(mian)差鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)。單(dan)面(mian)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban),即(ji)只在(zai)一面(mian)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)的(de)產(chan)品。在(zai)焊(han)接(jie)、涂裝(zhuang)、防(fang)銹(xiu)處(chu)理、加工等方面(mian),具有(you)比雙面(mian)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)好的(de)適應性(xing)。
熱鍍(du)鋅(xin)生(sheng)產(chan)發(fa)展一直(zhi)處于滯后狀態。20世(shi)(shi)紀(ji)(ji)50年(nian)代到(dao)60年(nian)代陸(lu)續建(jian)成了13條單張鋼(gang)板(ban)熔劑(ji)法(fa)熱鍍(du)鋅(xin)機組,能力為10萬t/a,但(dan)因產(chan)量(liang)(liang)低(di)、成本高(gao)、質量(liang)(liang)差、污(wu)染(ran)環(huan)境、經(jing)濟效(xiao)益差等缺陷已先后停、轉產(chan)。從20世(shi)(shi)紀(ji)(ji)70年(nian)代末,我國才開始建(jian)造大型寬(kuan)帶(dai)熱鍍(du)鋅(xin)機組。熱鍍(du)鋅(xin)帶(dai)鋼(gang)在我國市場(chang)一直(zhi)是緊(jin)缺品(pin)種(zhong)。從20世(shi)(shi)紀(ji)(ji)90年(nian)代中(zhong)期(qi)以(yi)來,每年(nian)都要從國外進口80-100萬t左(zuo)右。隨著國內(nei)經(jing)濟的發(fa)展,尤其是汽車、家電及建(jian)筑業的發(fa)展,對鍍(du)鋅(xin)帶(dai)鋼(gang)的需(xu)求量(liang)(liang)也大大增加(jia)。
要看整個(ge)(ge)樓板(ban)的(de)厚(hou)(hou)度來考慮挑選(xuan)是(shi)(shi)用75波(bo)高系列的(de)仍是(shi)(shi)51波(bo)高系列的(de),沉默有(you)40系列,46系列,60系列,65波(bo)高系列。一般(ban)(ban)來說波(bo)高越(yue)(yue)低(di),承載力(li)就越(yue)(yue)低(di),然后就是(shi)(shi)波(bo)峰距(ju)離(li)越(yue)(yue)大,承載力(li)就越(yue)(yue)小,假如(ru)整個(ge)(ge)樓板(ban)厚(hou)(hou)度在(zai)10公(gong)分(fen)以內,好(hao)選(xuan)用選(xuan)用波(bo)高40系列,整個(ge)(ge)樓板(ban)厚(hou)(hou)度在(zai)10-13公(gong)分(fen)以內,好(hao)選(xuan)用50波(bo)高系列,在(zai)13公(gong)分(fen)以上(shang),好(hao)選(xuan)用75系列。有(you)些人會(hui)問,為什么呀(ya)?其實(shi)《我國鋼(gang)筋混凝土修(xiu)建規范》里有(you)個(ge)(ge)要求,鋼(gang)筋上(shang)面的(de)混泥土保護層不能(neng)低(di)于(yu)2.5cm,就是(shi)(shi)說樓承板(ban)自身的(de)波(bo)高+鋼(gang)筋網(wang)的(de)厚(hou)(hou)度(一般(ban)(ban)2cm)+2.5cm的(de)保護層≤樓板(ban)的(de)厚(hou)(hou)度。
用電鍍(du)(du)法制(zhi)造這種(zhong)鍍(du)(du)鋅(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)具有(you)(you)(you)良好(hao)的(de)加工(gong)性。但(dan)鍍(du)(du)層較(jiao)薄,耐腐蝕性不如熱浸法鍍(du)(du)鋅(xin)板(ban)(ban)(ban)(ban)(ban);單面鍍(du)(du)和(he)雙面差(cha)鍍(du)(du)鋅(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)。單面鍍(du)(du)鋅(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban),即只(zhi)在一(yi)面鍍(du)(du)鋅(xin)的(de)產品。在焊接(jie)、涂(tu)裝(zhuang)、防銹處理、加工(gong)等方面,具有(you)(you)(you)比(bi)雙面鍍(du)(du)鋅(xin)板(ban)(ban)(ban)(ban)(ban)好(hao)的(de)適應(ying)性。為(wei)克(ke)服單面未涂(tu)鋅(xin)的(de)缺點,又有(you)(you)(you)一(yi)種(zhong)在另面涂(tu)以(yi)薄層鋅(xin)的(de)鍍(du)(du)鋅(xin)板(ban)(ban)(ban)(ban)(ban),即雙面差(cha)鍍(du)(du)鋅(xin)板(ban)(ban)(ban)(ban)(ban);合(he)金(jin)、復合(he)鍍(du)(du)鋅(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)。它是用鋅(xin)和(he)其他金(jin)屬如鉛、鋅(xin)制(zhi)成合(he)金(jin)乃至(zhi)復合(he)鍍(du)(du)成的(de)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)。這種(zhong)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)既(ji)具有(you)(you)(you)防銹性能(neng),又有(you)(you)(you)良好(hao)的(de)涂(tu)裝(zhuang)性能(neng)。 除上述五種(zhong)外,還有(you)(you)(you)彩色(se)鍍(du)(du)鋅(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)、印花涂(tu)裝(zhuang)鍍(du)(du)鋅(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)、聚氯乙烯疊層鍍(du)(du)鋅(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)等。但(dan)目前常用的(de)仍(reng)為(wei)熱浸鍍(du)(du)鋅(xin)板(ban)(ban)(ban)(ban)(ban)。 鍍(du)(du)鋅(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)按(an)用途(tu)又可分為(wei)一(yi)般用、屋(wu)頂用、建筑外側板(ban)(ban)(ban)(ban)(ban)用、結構用、瓦壟板(ban)(ban)(ban)(ban)(ban)用、拉伸用和(he)深沖用等鍍(du)(du)鋅(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)。
