鋁單板質量直接影響整個幕墻的質量，所以板材的收買質量控制是要害。

　　鋁(lv)(lv)單板(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)一(yi)(yi)般用純鋁(lv)(lv)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)。常用于外墻(qiang)的(de)鋁(lv)(lv)單板(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)厚度一(yi)(yi)般為2.5～3mm，為了(le)加(jia)(jia)(jia)強(qiang)(qiang)鋁(lv)(lv)單板(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)面(mian)強(qiang)(qiang)度，在鋁(lv)(lv)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)的(de)反(fan)面(mian)，有(you)必(bi)要裝置(zhi)加(jia)(jia)(jia)強(qiang)(qiang)筋(jin)，加(jia)(jia)(jia)強(qiang)(qiang)筋(jin)用厚的(de)鋁(lv)(lv)帶做成（板(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)的(de)加(jia)(jia)(jia)強(qiang)(qiang)筋(jin)由板(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)塊(kuai)的(de)位(wei)于不(bu)(bu)同的(de)高度計算(suan)其巨細(xi)），先用亮光焊(han)機把一(yi)(yi)顆(ke)顆(ke)螺(luo)絲帽焊(han)在鋁(lv)(lv)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)反(fan)面(mian)然(ran)后(hou)把作加(jia)(jia)(jia)強(qiang)(qiang)筋(jin)的(de)鋁(lv)(lv)條鉆孔套進螺(luo)絲內，用螺(luo)絲固(gu)定。鋁(lv)(lv)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)幕墻(qiang)的(de)鋁(lv)(lv)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)反(fan)面(mian)要安(an)加(jia)(jia)(jia)強(qiang)(qiang)筋(jin)，原因是在外界(jie)正負壓力的(de)情況下，鋁(lv)(lv)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)一(yi)(yi)不(bu)(bu)會(hui)洼陷，二不(bu)(bu)會(hui)鼓出(chu)(chu)，這樣就避免了(le)鋁(lv)(lv)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)幕墻(qiang)重(zhong)復里外振(zhen)動(dong)而發出(chu)(chu)的(de)振(zhen)動(dong)動(dong)靜。假設(she)需求隔音保溫，可在鋁(lv)(lv)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)內側(ce)安(an)放巖棉(mian)、礦渣棉(mian)或發泡(pao)處理。國內出(chu)(chu)產(chan)鋁(lv)(lv)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)廠家可按(an)用戶(hu)要求，制(zhi)造各(ge)(ge)種寬長、各(ge)(ge)種弧(hu)形(xing)異型幕墻(qiang)鋁(lv)(lv)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)，并焊(han)好加(jia)(jia)(jia)強(qiang)(qiang)筋(jin)。加(jia)(jia)(jia)強(qiang)(qiang)筋(jin)的(de)裝置(zhi)也很(hen)重(zhong)要，有(you)的(de)廠家的(de)加(jia)(jia)(jia)強(qiang)(qiang)筋(jin)沒有(you)用連接到鋁(lv)(lv)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)折(zhe)邊上，破壞了(le)加(jia)(jia)(jia)強(qiang)(qiang)筯的(de)傳力效果，使(shi)板(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)塊(kuai)使(shi)用后(hou)出(chu)(chu)現變(bian)形(xing)情況，影響(xiang)立(li)面(mian)效果。

　　幕墻鋁板外表處理可分為二種方法，一種是陽極氧化，另一種是靜電噴涂。陽極氧化的氧化膜一般在12μ以上，色彩只要古銅色和白色兩種，色彩單調，缺點是每塊鋁板板面的色彩深淺紛歧，許多塊幕墻板組合在一起形成的幕墻的全體效果非常丑陋。這個缺點可以說無法消除，并非出產技術形成的，而是由于鋁板并非是同一批號，化學成份有小的差別，再加上氧化時電解槽液電流密度等要素均無法完全相同，所以氧化后的色彩多少有差異。單張看或許不明顯，若都排在一起即非常明顯。所以鋁板幕墻的鋁板外表處理，決不能用陽極氧化。

　　幕(mu)墻(qiang)鋁(lv)(lv)板(ban)(ban)外(wai)表處理的(de)(de)另(ling)一(yi)(yi)種(zhong)方法是(shi)(shi)靜電噴(pen)(pen)涂(tu)(tu)。噴(pen)(pen)涂(tu)(tu)又分(fen)為粉(fen)(fen)(fen)(fen)沫(mo)噴(pen)(pen)涂(tu)(tu)和(he)液體(ti)噴(pen)(pen)涂(tu)(tu)。粉(fen)(fen)(fen)(fen)沫(mo)噴(pen)(pen)涂(tu)(tu)材(cai)料(liao)主要(yao)(yao)為：聚氨酯、聚脹樹(shu)脂(zhi)、環氧樹(shu)脂(zhi)等(deng)質(zhi)料(liao)配以高保色性顏料(liao)，可(ke)得(de)到(dao)幾(ji)(ji)十(shi)種(zhong)不(bu)同(tong)色彩(cai)(cai)的(de)(de)噴(pen)(pen)涂(tu)(tu)粉(fen)(fen)(fen)(fen)沫(mo)。該噴(pen)(pen)涂(tu)(tu)粉(fen)(fen)(fen)(fen)沫(mo)耐撞(zhuang)碰耐磨(mo)擦，在50公斤撞(zhuang)擊下，鋁(lv)(lv)板(ban)(ban)變(bian)形，噴(pen)(pen)涂(tu)(tu)層(ceng)無裂紋、無掉層(ceng)，完整無損，抗稀酸及砂漿。缺點只是(shi)(shi)怕紫外(wai)線長期(qi)照射，幾(ji)(ji)年后易發(fa)生陰陽面(mian)色彩(cai)(cai)的(de)(de)差(cha)(cha)異。國內不(bu)少廠家出產的(de)(de)噴(pen)(pen)涂(tu)(tu)粉(fen)(fen)(fen)(fen)沫(mo)，分(fen)量(liang)差(cha)(cha)異甚(shen)大，有(you)的(de)(de)粉(fen)(fen)(fen)(fen)沫(mo)含(han)金屑，這種(zhong)粉(fen)(fen)(fen)(fen)沫(mo)在掛到(dao)墻(qiang)面(mian)今后，隨陽光視點變(bian)化，白(bai)天和(he)黃昏有(you)變(bian)化，墻(qiang)面(mian)色彩(cai)(cai)深淺有(you)差(cha)(cha)異，選用粉(fen)(fen)(fen)(fen)沫(mo)噴(pen)(pen)涂(tu)(tu)料(liao)應引(yin)(yin)起留心。好點的(de)(de)涂(tu)(tu)料(liao)有(you)PPG、阿克蘇等(deng)。實際中(zhong)見(jian)到(dao)有(you)些幕(mu)墻(qiang)工程(cheng)完工后一(yi)(yi)、二年，外(wai)表顯得(de)舊、臟，便(bian)是(shi)(shi)氟(fu)碳涂(tu)(tu)層(ceng)的(de)(de)厚度或涂(tu)(tu)料(liao)引(yin)(yin)起的(de)(de)問題了。為避免問題的(de)(de)發(fa)生，要(yao)(yao)求控(kong)制好鋁(lv)(lv)板(ban)(ban)的(de)(de)質(zhi)量(liang)。在材(cai)料(liao)進場后，對鋁(lv)(lv)單板(ban)(ban)要(yao)(yao)送檢測機構進行(xing)板(ban)(ban)材(cai)成份(fen)、硬度、膜厚等(deng)檢測，確保所購材(cai)料(liao)的(de)(de)質(zhi)量(liang)。
