鋁(lv)單(dan)板(ban)是采用優質鋁(lv)合金(jin)板(ban)作為基(ji)板(ban),然后經過數控彎曲(qu)等技術成型,裝飾涂(tu)層外表噴涂(tu)新型幕墻資料。
鋁(lv)(lv)塑復(fu)合(he)板(ban)是經過(guo)化學處置的(de)鋁(lv)(lv)涂層外表資(zi)料(liao)(liao),以聚乙烯塑料(liao)(liao)為中(zhong)心資(zi)料(liao)(liao),在特種鋁(lv)(lv)塑板(ban)加工(gong)設(she)備和復(fu)合(he)資(zi)料(liao)(liao)加工(gong)中(zhong)。APCP自(zi)身的(de)共同性質決議了(le)它的(de)普遍用處:它可用于(yu)建(jian)筑(zhu)物外墻,幕墻板(ban),舊建(jian)筑(zhu)物創新(xin),內墻和天(tian)花板(ban)裝飾,廣告(gao)標志,展現(xian)架,粉塵凈化工(gong)程。鋁(lv)(lv)塑復(fu)合(he)板(ban)已(yi)在中(zhong)國(guo)得到普遍應用,屬于(yu)一種新(xin)型的(de)建(jian)筑(zhu)裝飾資(zi)料(liao)(liao)。
一(yi)、開展(zhan)歷史(shi)
幕(mu)墻的應(ying)用(yong)(yong)曾經有(you)幾十年(nian)了,至(zhi)今仍在(zai)使(shi)用(yong)(yong),包(bao)(bao)括鋁(lv)(lv)(lv)單(dan)板(ban)(ban)(ban)(ban),鋁(lv)(lv)(lv)塑(su)(su)復(fu)合(he)板(ban)(ban)(ban)(ban)和(he)(he)鋁(lv)(lv)(lv)蜂窩板(ban)(ban)(ban)(ban)三(san)種。在(zai)這(zhe)三(san)種資料(liao)中,最常(chang)用(yong)(yong)的是鋁(lv)(lv)(lv)單(dan)板(ban)(ban)(ban)(ban)和(he)(he)鋁(lv)(lv)(lv)塑(su)(su)板(ban)(ban)(ban)(ban)。鋁(lv)(lv)(lv)飾面(mian)首先(xian)呈現,后來(lai)在(zai)20世(shi)紀60年(nian)代(dai)末和(he)(he)70年(nian)代(dai)初(chu),APCP在(zai)德國(guo)創造(zao),并疾速在(zai)全世(shi)界流行。鋁(lv)(lv)(lv)和(he)(he)鋁(lv)(lv)(lv)單(dan)板(ban)(ban)(ban)(ban)到底有(you)什(shen)么區別(bie)?在(zai)這(zhe)里我將對這(zhe)兩種資料(liao)做一個簡單(dan)的比較:一,資料(liao)和(he)(he)本(ben)錢(qian)鋁(lv)(lv)(lv)單(dan)板(ban)(ban)(ban)(ban)普通采(cai)用(yong)(yong)2-4mm厚(hou)(hou)的AA1100純(chun)鋁(lv)(lv)(lv)或AA3003鋁(lv)(lv)(lv)合(he)金板(ban)(ban)(ban)(ban),國(guo)內(nei)普通采(cai)用(yong)(yong)2.5mm厚(hou)(hou)的AA3003鋁(lv)(lv)(lv)合(he)金板(ban)(ban)(ban)(ban); APCP普通采(cai)用(yong)(yong)3-4mm三(san)層(ceng)構造(zao),包(bao)(bao)括上下(xia)兩個0.5mm夾層(ceng)PVC或PE。從(cong)資料(liao)上我們能夠看出,APCP的本(ben)錢(qian)必需遠(yuan)低于(yu)鋁(lv)(lv)(lv)單(dan)板(ban)(ban)(ban)(ban)。目前市(shi)場上約(yue)4mm厚(hou)(hou)的復(fu)合(he)板(ban)(ban)(ban)(ban)以(yi)2.5mm厚(hou)(hou)的價錢(qian)低于(yu)120元(yuan)/平方(fang),一萬(wan)平方(fang)的工程,使(shi)用(yong)(yong)鋁(lv)(lv)(lv)塑(su)(su)板(ban)(ban)(ban)(ban)比使(shi)用(yong)(yong)鋁(lv)(lv)(lv)單(dan)板(ban)(ban)(ban)(ban)降低本(ben)錢(qian)120萬(wan)元(yuan)。
二、生產過程
目前(qian)(qian),世界上(shang)鋁(lv)(lv)(lv)(lv)單(dan)板(ban)上(shang)有(you)(you)(you)兩(liang)種氟碳噴(pen)(pen)(pen)涂(tu)(tu)鋁(lv)(lv)(lv)(lv)單(dan)板(ban)和(he)(he)輥(gun)涂(tu)(tu)。目前(qian)(qian)我國還(huan)沒有(you)(you)(you)棒涂(tu)(tu)生(sheng)產線,因而這(zhe)里的(de)(de)(de)膠合板(ban)加(jia)(jia)(jia)工主(zhu)要(yao)是(shi)指氟碳噴(pen)(pen)(pen)涂(tu)(tu)消費。噴(pen)(pen)(pen)涂(tu)(tu)鋁(lv)(lv)(lv)(lv)單(dan)板(ban)的(de)(de)(de)生(sheng)產分為兩(liang)步(bu):第(di)一步(bu)是(shi)鈑金加(jia)(jia)(jia)工。這(zhe)個過程(cheng)(cheng)主(zhu)要(yao)是(shi)經(jing)過板(ban)材(cai)經(jing)過切割,折疊,彎曲,焊接,研磨等工藝(yi),將鋁(lv)(lv)(lv)(lv)單(dan)板(ban)加(jia)(jia)(jia)工成所要(yao)的(de)(de)(de)外形和(he)(he)尺(chi)寸的(de)(de)(de)構(gou)造。第(di)二步(bu)是(shi)噴(pen)(pen)(pen)涂(tu)(tu)。噴(pen)(pen)(pen)涂(tu)(tu)是(shi)在(zai)金屬板(ban)噴(pen)(pen)(pen)涂(tu)(tu)漆的(de)(de)(de)加(jia)(jia)(jia)工過程(cheng)(cheng)中。噴(pen)(pen)(pen)涂(tu)(tu)分為兩(liang)種,一種是(shi)人(ren)工噴(pen)(pen)(pen)涂(tu)(tu),一種是(shi)機噴(pen)(pen)(pen)涂(tu)(tu)。機器涂(tu)(tu)層(ceng)普(pu)通(tong)只(zhi)合適(shi)平板(ban)的(de)(de)(de)規則,但這(zhe)種鋁(lv)(lv)(lv)(lv)單(dan)板(ban)在(zai)實踐使用(yong)中較少,國內大(da)多(duo)數廠家采用(yong)人(ren)工噴(pen)(pen)(pen)涂(tu)(tu)。人(ren)工噴(pen)(pen)(pen)灑是(shi)一項(xiang)風險的(de)(de)(de)工作,由于涂(tu)(tu)料揮(hui)發(fa)性(xing)和(he)(he)毒(du)性(xing)相對(dui)較強,很可能惹(re)起(qi)慢性(xing)苯中毒(du),嚴重影(ying)響人(ren)體(ti)健康。人(ren)工噴(pen)(pen)(pen)涂(tu)(tu)的(de)(de)(de)一大(da)優點是(shi)無論尺(chi)寸大(da)小,顏色都(dou)是(shi)可選的(de)(de)(de),并(bing)且鋁(lv)(lv)(lv)(lv)塑涂(tu)(tu)層(ceng)輥(gun)必需到達一定量才干加(jia)(jia)(jia)工。鋁(lv)(lv)(lv)(lv)板(ban)的(de)(de)(de)加(jia)(jia)(jia)工比(bi)鋁(lv)(lv)(lv)(lv)單(dan)板(ban)更(geng)復雜,化(hua)學成型,涂(tu)(tu)裝,復合和(he)(he)修(xiu)邊有(you)(you)(you)四個主(zhu)要(yao)過程(cheng)(cheng)。除了修(xiu)剪之外,這(zhe)四個過程(cheng)(cheng)都(dou)是(shi)自動化(hua)消費。從它(ta)的(de)(de)(de)處置能夠看出,鋁(lv)(lv)(lv)(lv)塑板(ban)在(zai)環境和(he)(he)安全(quan)方面具(ju)有(you)(you)(you)一定的(de)(de)(de)優越性(xing)。再加(jia)(jia)(jia)上(shang)鈑金加(jia)(jia)(jia)鋁(lv)(lv)(lv)(lv)單(dan)板(ban)的(de)(de)(de)簡單(dan)工藝(yi),一些私(si)人(ren)車間(jian)曾經(jing)開端涉足(zu),嚴重影(ying)響鋁(lv)(lv)(lv)(lv)單(dan)板(ban)市場穩定的(de)(de)(de)質量。
三、產品外觀質量和物理性(xing)能(neng)
2.5mm鋁(lv)(lv)(lv)單板(ban)4mm厚鋁(lv)(lv)(lv)塑復合板(ban)外(wai)觀質(zhi)量(liang)平整(zheng)(zheng)度(du)(du)不平整(zheng)(zheng),看起來(lai)局(ju)部(bu)凹凸,平整(zheng)(zheng)度(du)(du)較(jiao)高(gao),但(dan)加工(gong)(gong)外(wai)形有限; 但(dan)可加工(gong)(gong)成各種不規則外(wai)形; 噴涂(tu)(tu)輥(gun)涂(tu)(tu)層的(de)(de)眼睛質(zhi)量(liang),顏(yan)色和(he)薄膜厚度(du)(du)偏(pian)向(xiang)由于(yu)人工(gong)(gong)技術的(de)(de)不穩定性(xing),沒(mei)有明(ming)顯的(de)(de)部(bu)分色差,但(dan)損(sun)壞無(wu)法修(xiu)復。和(he)薄膜厚度(du)(du)偏(pian)向(xiang); 部(bu)分損(sun)壞能(neng)夠(gou)修(xiu)復。抗拉強度(du)(du)130 / mm 38-61N / mm2X伸長率5%-10%12%-17%彎(wan)曲強度(du)(du)84.2N / mm 34N / mm2彈性(xing)模量(liang)70.00N / mm2 26.136-49.050N / mm2從上表能(neng)夠(gou)看出鋁(lv)(lv)(lv)單板(ban)的(de)(de)外(wai)觀比鋁(lv)(lv)(lv)更差,但(dan)其機械性(xing)能(neng)明(ming)顯優于(yu)鋁(lv)(lv)(lv)塑板(ban),其風壓性(xing)能(neng)也優于(yu)鋁(lv)(lv)(lv)塑板(ban)。但(dan)是,在(zai)我國(guo)大局(ju)部(bu)地域,鋁(lv)(lv)(lv)板(ban)的(de)(de)風壓值是能(neng)夠(gou)接(jie)受(shou)的(de)(de),所以鋁(lv)(lv)(lv)單板(ban)項目的(de)(de)使用有點矯枉(wang)過(guo)正。
四(si)、安裝過程
鋁(lv)和鋁(lv)單(dan)板(ban)的(de)(de)(de)裝(zhuang)置(zhi)工藝大致相同。最(zui)大的(de)(de)(de)不(bu)是鋁(lv)塑板(ban)在(zai)(zai)現場加工成(cheng)所(suo)要的(de)(de)(de)外形(xing)和尺寸,具有更(geng)大的(de)(de)(de)構(gou)造自(zi)在(zai)(zai)度(du)。鋁(lv)單(dan)板(ban)加工是在(zai)(zai)工廠構(gou)成(cheng)的(de)(de)(de),由于國產設(she)備的(de)(de)(de)精確性,常常在(zai)(zai)裝(zhuang)置(zhi)過(guo)程(cheng)中(zhong)會遇到一些小問題(ti)。此(ci)外,在(zai)(zai)裝(zhuang)置(zhi)過(guo)程(cheng)中(zhong),APCP的(de)(de)(de)批量生產比鋁(lv)單(dan)板(ban)的(de)(de)(de)生產快得多,并且(qie)進(jin)度(du)保證系(xi)統也高。
五、比較(jiao)的(de)其他方(fang)面
1,防雷(lei)功(gong)用
這個問(wen)題曾經爭論了很長時(shi)間(jian),人們真的以為鋁(lv)(lv)單(dan)板是(shi)純鋁(lv)(lv),導電性(xing)能更好(hao)。針對(dui)這一問(wen)題,德(de)國ALUSUISSESINGEN GMBH公司在德(de)國慕(mu)尼黑的一個軍(jun)事實驗室做了兩(liang)種資料的防(fang)雷實驗。結果標明,當(dang)(dang)雷擊(ji)(ji)霎時(shi),目前(qian)的幕墻銜(xian)接方式(shi),無論是(shi)鋁(lv)(lv)或鋁(lv)(lv)單(dan)板,都能完整避免(mian)雷擊(ji)(ji); 當(dang)(dang)雷擊(ji)(ji)到(dao)連續(xu)電流時(shi),金屬板或金屬外表(biao)層閃電部容(rong)易(yi)凝結。鋁(lv)(lv)塑復合(he)板由于中間(jian)的聚乙(yi)烯中心具有良好(hao)的絕緣性(xing),閃電損(sun)壞僅(jin)限于表(biao)皮,從(cong)這個角(jiao)度來看,
2,防火(huo)特性
鋁(lv)單板不(bu)(bu)熄(xi)滅,我們(men)都知道。早期的鋁(lv)塑板不(bu)(bu)防火,但隨(sui)著鋁(lv)塑板技術的發(fa)展(zhan),如今能夠使用防火鋁(lv)塑復合板,由于它的無毒阻燃PE材(cai)料,提(ti)高了防火性(xing)能,有可能滿(man)足工程火災的需(xu)求。
3,殘留價值
鋁(lv)(lv)單板(ban)具有(you)一定(ding)的殘留價值(zhi),但由于其成(cheng)本高,其造成(cheng)的浪(lang)費仍(reng)遠大于鋁(lv)(lv)塑復合單板(ban),簡直(zhi)沒有(you)殘留值(zhi)。綜上所述(shu),鋁(lv)(lv)單板(ban)和鋁(lv)(lv)塑復合板(ban)各有(you)優勢,但從大的角度來(lai)看,鋁(lv)(lv)塑板(ban)的應(ying)用應(ying)該(gai)更(geng)加實惠和環保(bao)。
