金屬板幕墻應用已經有了幾十年的歷史，現在還在使用的包括有鋁單板、鋁塑復合板和鋁蜂窩板(ban)(ban)三種。在這(zhe)三種材(cai)料(liao)中(zhong)，最常用的是鋁(lv)(lv)單板(ban)(ban)和(he)鋁(lv)(lv)塑(su)板(ban)(ban)。鋁(lv)(lv)單板(ban)(ban)出(chu)現的最早，后來在６０年代末７０年代初，鋁(lv)(lv)塑(su)復合板(ban)(ban)在德國發明，并迅(xun)速(su)風行全球。鋁(lv)(lv)塑(su)板(ban)(ban)和(he)鋁(lv)(lv)單板(ban)(ban)到底有什么區別(bie)呢？在此我將這(zhe)兩種材(cai)料(liao)做一(yi)個簡單的比較：

　　一、料和造價

　　鋁(lv)(lv)單(dan)板(ban)一般(ban)(ban)采用２－４ｍｍ厚(hou)的(de)(de)(de)ＡＡ１１００純鋁(lv)(lv)板(ban)或ＡＡ３００３的(de)(de)(de)鋁(lv)(lv)合(he)(he)(he)金(jin)板(ban)，國內(nei)一般(ban)(ban)使用２．５ｍｍ厚(hou)ＡＡ３００３鋁(lv)(lv)合(he)(he)(he)金(jin)板(ban)；鋁(lv)(lv)塑(su)復合(he)(he)(he)板(ban)一般(ban)(ban)采用３－４ｍｍ三層結構，包括上(shang)下兩(liang)個０．５ｍｍ夾著ＰＶＣ或ＰＥ。我們(men)從材料可以看出(chu)，鋁(lv)(lv)塑(su)復合(he)(he)(he)板(ban)的(de)(de)(de)造(zao)價肯定要(yao)(yao)(yao)比(bi)鋁(lv)(lv)單(dan)板(ban)要(yao)(yao)(yao)低(di)的(de)(de)(de)多(duo)。目前的(de)(de)(de)市場大概是４ｍｍ厚(hou)的(de)(de)(de)復合(he)(he)(he)板(ban)要(yao)(yao)(yao)比(bi)２．５ｍｍ厚(hou)的(de)(de)(de)價格要(yao)(yao)(yao)低(di)１２０元／平方以上(shang)，一個一萬方的(de)(de)(de)工程，使用鋁(lv)(lv)塑(su)板(ban)就要(yao)(yao)(yao)比(bi)使用鋁(lv)(lv)單(dan)板(ban)降(jiang)低(di)１２０萬元的(de)(de)(de)造(zao)價。

　　二、加工過程

　　目前世界上的(de)(de)(de)鋁單板(ban)(ban)(ban)(ban)有氟碳噴(pen)(pen)涂(tu)(tu)鋁單板(ban)(ban)(ban)(ban)和輥(gun)涂(tu)(tu)兩種(zhong)(zhong)，國(guo)內(nei)暫時(shi)還沒有棍涂(tu)(tu)生產(chan)(chan)線，所(suo)以這里(li)單板(ban)(ban)(ban)(ban)的(de)(de)(de)加(jia)工(gong)(gong)(gong)過(guo)程主(zhu)(zhu)要(yao)是(shi)(shi)講的(de)(de)(de)氟碳噴(pen)(pen)涂(tu)(tu)生產(chan)(chan)。噴(pen)(pen)涂(tu)(tu)生產(chan)(chan)鋁單板(ban)(ban)(ban)(ban)分(fen)為兩大(da)步(bu)驟(zou)：第一(yi)步(bu)是(shi)(shi)鈑(ban)金(jin)(jin)加(jia)工(gong)(gong)(gong)。這個過(guo)程主(zhu)(zhu)要(yao)是(shi)(shi)通過(guo)對平(ping)板(ban)(ban)(ban)(ban)經過(guo)裁剪(jian)、折邊(bian)、彎弧、焊接(jie)、打(da)磨等(deng)工(gong)(gong)(gong)序(xu)，把鋁單板(ban)(ban)(ban)(ban)加(jia)工(gong)(gong)(gong)成施工(gong)(gong)(gong)所(suo)需的(de)(de)(de)形狀和尺寸。第二步(bu)就是(shi)(shi)噴(pen)(pen)涂(tu)(tu)。噴(pen)(pen)涂(tu)(tu)就是(shi)(shi)在加(jia)工(gong)(gong)(gong)好的(de)(de)(de)鈑(ban)金(jin)(jin)上噴(pen)(pen)涂(tu)(tu)油漆(qi)(qi)。噴(pen)(pen)涂(tu)(tu)分(fen)為兩種(zhong)(zhong)，一(yi)種(zhong)(zhong)是(shi)(shi)人(ren)工(gong)(gong)(gong)噴(pen)(pen)涂(tu)(tu)，一(yi)種(zhong)(zhong)是(shi)(shi)機器(qi)噴(pen)(pen)涂(tu)(tu)。機器(qi)噴(pen)(pen)涂(tu)(tu)一(yi)般只適合規則的(de)(de)(de)平(ping)板(ban)(ban)(ban)(ban)，但這種(zhong)(zhong)鋁單板(ban)(ban)(ban)(ban)在實(shi)際的(de)(de)(de)使用中(zhong)用的(de)(de)(de)比較(jiao)少，國(guo)內(nei)大(da)部分(fen)廠(chang)家(jia)采用的(de)(de)(de)人(ren)工(gong)(gong)(gong)噴(pen)(pen)涂(tu)(tu)。人(ren)工(gong)(gong)(gong)噴(pen)(pen)涂(tu)(tu)是(shi)(shi)一(yi)個危險的(de)(de)(de)工(gong)(gong)(gong)作，因為油漆(qi)(qi)的(de)(de)(de)揮發性和毒性都(dou)(dou)比較(jiao)強，很容(rong)易造成慢性苯系列中(zhong)毒，嚴重影響人(ren)的(de)(de)(de)健康。人(ren)工(gong)(gong)(gong)噴(pen)(pen)涂(tu)(tu)的(de)(de)(de)一(yi)大(da)優點就是(shi)(shi)不(bu)管量(liang)的(de)(de)(de)大(da)小，顏色都(dou)(dou)可以任選，而鋁塑板(ban)(ban)(ban)(ban)的(de)(de)(de)輥(gun)涂(tu)(tu)必須(xu)達到一(yi)定量(liang)才(cai)可以加(jia)工(gong)(gong)(gong)。鋁塑板(ban)(ban)(ban)(ban)的(de)(de)(de)加(jia)工(gong)(gong)(gong)過(guo)程較(jiao)之鋁單板(ban)(ban)(ban)(ban)復(fu)雜(za)一(yi)些，主(zhu)(zhu)要(yao)是(shi)(shi)有化成、涂(tu)(tu)裝(zhuang)、復(fu)合和修(xiu)邊(bian)四(si)(si)大(da)工(gong)(gong)(gong)序(xu)，這四(si)(si)個過(guo)程除了修(xiu)邊(bian)以外其它都(dou)(dou)是(shi)(shi)自動化生產(chan)(chan)。

　　三、產品的外(wai)觀質量和(he)物理性能

　　從上表可(ke)以看出，鋁(lv)(lv)單板(ban)(ban)(ban)的外觀比鋁(lv)(lv)塑板(ban)(ban)(ban)差(cha)一些，但是其機械(xie)性能明顯優(you)于鋁(lv)(lv)塑板(ban)(ban)(ban)，其抗風壓性能也優(you)于鋁(lv)(lv)塑板(ban)(ban)(ban)。但是在我國大部地區，其風壓值鋁(lv)(lv)塑板(ban)(ban)(ban)是完全可(ke)以承受，所以，工程使用(yong)鋁(lv)(lv)單板(ban)(ban)(ban)有點大材小用(yong)。

　　四、施工過程

　　鋁(lv)塑(su)板和鋁(lv)單(dan)板的施工過(guo)程大體(ti)是(shi)相同(tong)的。最大的不是(shi)鋁(lv)塑(su)板是(shi)在工地加工成所需形(xing)狀和規(gui)格，有著較大的施工自(zi)由(you)(you)度(du)。而鋁(lv)單(dan)板是(shi)中(zhong)廠(chang)家(jia)加工成形(xing)，由(you)(you)于國內設備(bei)精度(du)的關(guan)系，往往在施工過(guo)程中(zhong)會遇到(dao)一些小小的挑(tiao)戰。所以(yi)鋁(lv)單(dan)板和鋁(lv)塑(su)板各有千(qian)秋(qiu)。
