鋁單板的比較
時間:2021-10-09?? 瀏覽:1758次

  金(jin)屬板(ban)(ban)幕墻應用(yong)(yong)已(yi)經有(you)了幾十(shi)年(nian)的(de)(de)歷(li)史,還在(zai)使用(yong)(yong)的(de)(de)包括有(you)鋁(lv)(lv)(lv)單(dan)(dan)板(ban)(ban)、鋁(lv)(lv)(lv)塑復(fu)合板(ban)(ban)和(he)鋁(lv)(lv)(lv)蜂窩板(ban)(ban)三(san)種。在(zai)這(zhe)三(san)種材(cai)料中,常用(yong)(yong)的(de)(de)是(shi)鋁(lv)(lv)(lv)單(dan)(dan)板(ban)(ban)和(he)鋁(lv)(lv)(lv)塑板(ban)(ban)。鋁(lv)(lv)(lv)單(dan)(dan)板(ban)(ban)出(chu)現的(de)(de)早,后來在(zai)60年(nian)代末70年(nian)代初,鋁(lv)(lv)(lv)塑復(fu)合板(ban)(ban)在(zai)德國發明(ming),并迅速風行全球。鋁(lv)(lv)(lv)塑板(ban)(ban)和(he)鋁(lv)(lv)(lv)單(dan)(dan)板(ban)(ban)到底有(you)什么區(qu)別呢?在(zai)此我將這(zhe)兩種材(cai)料做一個簡單(dan)(dan)的(de)(de)比較:

  材料和造價

  鋁(lv)單板(ban)一(yi)般采用(yong)2-4mm厚(hou)的(de)(de)(de)AA1100純(chun)鋁(lv)板(ban)或AA3003等優質鋁(lv)合(he)金(jin)板(ban),國內一(yi)般使用(yong)2.5mm厚(hou)AA3003鋁(lv)合(he)金(jin)板(ban);鋁(lv)塑復(fu)合(he)板(ban)一(yi)般采用(yong)3-4mm三層結構,包括上下兩個0.5mm夾著PVC或PE。我(wo)們(men)從材料可(ke)以看出(chu),鋁(lv)塑復(fu)合(he)板(ban)的(de)(de)(de)造價肯定要(yao)比(bi)(bi)(bi)鋁(lv)單板(ban)要(yao)低(di)(di)的(de)(de)(de)多。市場大概(gai)是4mm厚(hou)的(de)(de)(de)復(fu)合(he)板(ban)要(yao)比(bi)(bi)(bi)2.5mm厚(hou)的(de)(de)(de)鋁(lv)單板(ban)價格要(yao)低(di)(di)120元(yuan)/平(ping)方(fang)以上,一(yi)個一(yi)萬方(fang)的(de)(de)(de)工(gong)程,使用(yong)鋁(lv)塑板(ban)就要(yao)比(bi)(bi)(bi)使用(yong)鋁(lv)單板(ban)降(jiang)低(di)(di)120萬元(yuan)的(de)(de)(de)造價。

  加工過程

  世界上(shang)的(de)(de)(de)(de)鋁(lv)(lv)(lv)單板(ban)有(you)氟(fu)碳噴(pen)(pen)涂(tu)(tu)(tu)(tu)(tu)(tu)鋁(lv)(lv)(lv)單板(ban)和(he)輥涂(tu)(tu)(tu)(tu)(tu)(tu)兩(liang)種(zhong),國內暫時還沒有(you)棍(gun)涂(tu)(tu)(tu)(tu)(tu)(tu)生產(chan)(chan)線,所以(yi)這(zhe)里單板(ban)的(de)(de)(de)(de)加(jia)(jia)工(gong)(gong)(gong)(gong)過(guo)程主要是(shi)(shi)(shi)(shi)(shi)(shi)講的(de)(de)(de)(de)氟(fu)碳噴(pen)(pen)涂(tu)(tu)(tu)(tu)(tu)(tu)生產(chan)(chan)。噴(pen)(pen)涂(tu)(tu)(tu)(tu)(tu)(tu)生產(chan)(chan)鋁(lv)(lv)(lv)單板(ban)分(fen)為(wei)兩(liang)大(da)(da)步驟:第 一(yi)步是(shi)(shi)(shi)(shi)(shi)(shi)鈑金(jin)加(jia)(jia)工(gong)(gong)(gong)(gong)。這(zhe)個(ge)過(guo)程主要是(shi)(shi)(shi)(shi)(shi)(shi)通過(guo)對(dui)平板(ban)經過(guo)裁剪、折邊(bian)、彎弧、焊接、打磨等工(gong)(gong)(gong)(gong)序,把(ba)鋁(lv)(lv)(lv)單板(ban)加(jia)(jia)工(gong)(gong)(gong)(gong)成施工(gong)(gong)(gong)(gong)所需的(de)(de)(de)(de)形(xing)狀(zhuang)和(he)尺寸。第二(er)步就(jiu)(jiu)是(shi)(shi)(shi)(shi)(shi)(shi)噴(pen)(pen)涂(tu)(tu)(tu)(tu)(tu)(tu)。噴(pen)(pen)涂(tu)(tu)(tu)(tu)(tu)(tu)就(jiu)(jiu)是(shi)(shi)(shi)(shi)(shi)(shi)在加(jia)(jia)工(gong)(gong)(gong)(gong)好的(de)(de)(de)(de)鈑金(jin)上(shang)噴(pen)(pen)涂(tu)(tu)(tu)(tu)(tu)(tu)油漆。噴(pen)(pen)涂(tu)(tu)(tu)(tu)(tu)(tu)分(fen)為(wei)兩(liang)種(zhong),一(yi)種(zhong)是(shi)(shi)(shi)(shi)(shi)(shi)人(ren)工(gong)(gong)(gong)(gong)噴(pen)(pen)涂(tu)(tu)(tu)(tu)(tu)(tu),一(yi)種(zhong)是(shi)(shi)(shi)(shi)(shi)(shi)機(ji)器噴(pen)(pen)涂(tu)(tu)(tu)(tu)(tu)(tu)。機(ji)器噴(pen)(pen)涂(tu)(tu)(tu)(tu)(tu)(tu)一(yi)般只(zhi)適(shi)合(he)規(gui)則的(de)(de)(de)(de)平板(ban),但這(zhe)種(zhong)鋁(lv)(lv)(lv)單板(ban)在實際的(de)(de)(de)(de)使用中用的(de)(de)(de)(de)比較(jiao)少,國內大(da)(da)部分(fen)廠家采用的(de)(de)(de)(de)人(ren)工(gong)(gong)(gong)(gong)噴(pen)(pen)涂(tu)(tu)(tu)(tu)(tu)(tu)。人(ren)工(gong)(gong)(gong)(gong)噴(pen)(pen)涂(tu)(tu)(tu)(tu)(tu)(tu)是(shi)(shi)(shi)(shi)(shi)(shi)一(yi)個(ge)危險的(de)(de)(de)(de)工(gong)(gong)(gong)(gong)作,因為(wei)油漆的(de)(de)(de)(de)揮發性(xing)和(he)毒(du)性(xing)都比較(jiao)強,很容易造成慢性(xing)苯系列中毒(du),嚴重影響(xiang)人(ren)的(de)(de)(de)(de)健(jian)康。人(ren)工(gong)(gong)(gong)(gong)噴(pen)(pen)涂(tu)(tu)(tu)(tu)(tu)(tu)的(de)(de)(de)(de)一(yi)大(da)(da)優(you)點(dian)就(jiu)(jiu)是(shi)(shi)(shi)(shi)(shi)(shi)不(bu)管量(liang)的(de)(de)(de)(de)大(da)(da)小(xiao),顏色都可(ke)以(yi)任選,而鋁(lv)(lv)(lv)塑板(ban)的(de)(de)(de)(de)輥涂(tu)(tu)(tu)(tu)(tu)(tu)必須(xu)達(da)到一(yi)定(ding)量(liang)才(cai)可(ke)以(yi)加(jia)(jia)工(gong)(gong)(gong)(gong)。鋁(lv)(lv)(lv)塑板(ban)的(de)(de)(de)(de)加(jia)(jia)工(gong)(gong)(gong)(gong)過(guo)程較(jiao)之(zhi)鋁(lv)(lv)(lv)單板(ban)復雜一(yi)些,主要是(shi)(shi)(shi)(shi)(shi)(shi)有(you)化(hua)成、涂(tu)(tu)(tu)(tu)(tu)(tu)裝、復合(he)和(he)修(xiu)邊(bian)四大(da)(da)工(gong)(gong)(gong)(gong)序,這(zhe)四個(ge)過(guo)程除(chu)了(le)修(xiu)邊(bian)以(yi)外(wai)其它(ta)都是(shi)(shi)(shi)(shi)(shi)(shi)自動(dong)化(hua)生產(chan)(chan)。從其加(jia)(jia)工(gong)(gong)(gong)(gong)過(guo)程可(ke)以(yi)看出,鋁(lv)(lv)(lv)塑板(ban)在環保和(he)安全性(xing)方面占有(you)一(yi)定(ding)的(de)(de)(de)(de)優(you)越(yue)性(xing)。再加(jia)(jia)上(shang)鋁(lv)(lv)(lv)單板(ban)的(de)(de)(de)(de)鈑金(jin)加(jia)(jia)工(gong)(gong)(gong)(gong)過(guo)程的(de)(de)(de)(de)簡易,有(you)些私(si)人(ren)作坊也開始(shi)涉(she)足,嚴重影響(xiang)了(le)鋁(lv)(lv)(lv)單板(ban)的(de)(de)(de)(de)市場質量(liang)的(de)(de)(de)(de)穩定(ding)。

  產品

  項目 2.5mm鋁單板 4mm厚的鋁塑復合板

  外觀質量 平板平整(zheng)度不(bu)高(gao),看上去有(you)局部凹凸, 平板平整(zheng)度比較高(gao),但加(jia)工型狀(zhuang)受限(xian);

  但可以加(jia)工成各種(zhong)不規則形狀(zhuang); 噴涂(tu) 輥涂(tu)質量(liang)眼觀質量(liang)好,色差和膜厚偏差

  由(you)于人工技(ji)術的不(bu)(bu)(bu)穩定,有局部色差(cha) 不(bu)(bu)(bu)明顯,但(dan)損(sun)壞不(bu)(bu)(bu)可局部修補。

  和(he)膜厚(hou)偏差;局部損壞可以修補。

  機(ji)抗拉強(qiang)度 130/mm 38-61N/mm2X

  機械伸(shen)長度 5%-10% 12%-17%

  折彎強(qiang)度 84.2N/mm 34N/mm2

  能(neng)彈性模量 70.00N/mm2 26.136-49.050N/mm2

  從上表可以(yi)看出(chu),鋁(lv)(lv)單(dan)板的(de)外觀比鋁(lv)(lv)塑板差一些,但是(shi)其(qi)機械性能明(ming)顯優于鋁(lv)(lv)塑板,其(qi)抗(kang)風(feng)壓(ya)性能也優于鋁(lv)(lv)塑板。但是(shi)在我國(guo)大(da)(da)部(bu)地區,其(qi)風(feng)壓(ya)值鋁(lv)(lv)塑板是(shi)完全可以(yi)承受,所以(yi),工程使(shi)用(yong)鋁(lv)(lv)單(dan)板有點(dian)大(da)(da)材小用(yong)。

  施工過程

  鋁(lv)(lv)塑板(ban)(ban)和鋁(lv)(lv)單板(ban)(ban)的(de)(de)施(shi)工過程大體是(shi)相同(tong)的(de)(de)。大的(de)(de)不(bu)是(shi)鋁(lv)(lv)塑板(ban)(ban)是(shi)在(zai)工地加工成(cheng)所需形(xing)狀和規(gui)格,有著較大的(de)(de)施(shi)工自由度。而(er)鋁(lv)(lv)單板(ban)(ban)是(shi)中廠家加工成(cheng)形(xing),由于國內設(she)備精度的(de)(de)關系,往往在(zai)施(shi)工過程中會遇到一些小(xiao)(xiao)小(xiao)(xiao)的(de)(de)麻煩。另(ling)外施(shi)工過程交貨(huo)期的(de)(de)保證方面,鋁(lv)(lv)塑復合(he)板(ban)(ban)的(de)(de)批量生產要比鋁(lv)(lv)單板(ban)(ban)生產快(kuai)得多,工期進(jin)度保證系統也(ye)高一些。
