一(yi)、塑板的變(bian)色、脫色

鋁(lv)塑板(ban)(ban)產生變(bian)色、脫(tuo)色，主要是由于板(ban)(ban)材(cai)(cai)(cai)選用(yong)(yong)(yong)不當造(zao)成(cheng)的(de)(de)(de)。鋁(lv)塑板(ban)(ban)分為室(shi)內用(yong)(yong)(yong)板(ban)(ban)和室(shi)外(wai)用(yong)(yong)(yong)板(ban)(ban)，兩種板(ban)(ban)材(cai)(cai)(cai)的(de)(de)(de)表面涂(tu)層不同，決定了其(qi)適用(yong)(yong)(yong)的(de)(de)(de)不同場合。室(shi)內所(suo)用(yong)(yong)(yong)的(de)(de)(de)板(ban)(ban)材(cai)(cai)(cai)，其(qi)表面一(yi)般噴涂(tu)樹(shu)脂涂(tu)層，這(zhe)種涂(tu)層適應不了室(shi)外(wai)惡劣的(de)(de)(de)自然環境，如果用(yong)(yong)(yong)在了室(shi)外(wai)，自然會(hui)加速其(qi)老化(hua)過(guo)程，引起了變(bian)色脫(tuo)色現(xian)象。室(shi)外(wai)鋁(lv)塑板(ban)(ban)的(de)(de)(de)表面涂(tu)層一(yi)般選用(yong)(yong)(yong)抗老化(hua)、抗紫(zi)外(wai)線(xian)能力較強的(de)(de)(de)聚氟彈脂涂(tu)層，這(zhe)種板(ban)(ban)材(cai)(cai)(cai)的(de)(de)(de)價格昂貴。有些(xie)施工(gong)(gong)單位欺騙業(ye)主，以室(shi)內用(yong)(yong)(yong)的(de)(de)(de)板(ban)(ban)材(cai)(cai)(cai)冒充抗老化(hua)、抗腐蝕的(de)(de)(de)優質氟碳(tan)板(ban)(ban)材(cai)(cai)(cai)，榨取不合理的(de)(de)(de)利潤，因而造(zao)成(cheng)工(gong)(gong)程上所(suo)用(yong)(yong)(yong)的(de)(de)(de)鋁(lv)板(ban)(ban)出現(xian)嚴重的(de)(de)(de)變(bian)色、脫(tuo)色現(xian)象。

二(er)、塑板(ban)的(de)開(kai)膠、脫落

鋁(lv)(lv)塑板(ban)(ban)開(kai)膠(jiao)、脫落，主要(yao)是(shi)由于粘結(jie)劑選用(yong)不當的(de)(de)(de)(de)。作(zuo)為(wei)室(shi)外鋁(lv)(lv)塑板(ban)(ban)工程(cheng)的(de)(de)(de)(de)理(li)想粘結(jie)劑，硅(gui)酮(tong)(tong)膠(jiao)有著(zhu)得天獨厚的(de)(de)(de)(de)優(you)越條(tiao)件(jian)。以前，我(wo)國的(de)(de)(de)(de)硅(gui)酮(tong)(tong)膠(jiao)主要(yao)依賴進口，其(qi)身價(jia)(jia)令很多(duo)人望(wang)而卻(que)步，只有那(nei)些高層(ceng)建筑上身價(jia)(jia)不菲的(de)(de)(de)(de)幕墻工程(cheng)才敢(gan)于問(wen)津。現在(zai)，我(wo)國的(de)(de)(de)(de)鄭(zheng)州(zhou)、廣東、杭州(zhou)等(deng)地都先(xian)后投產了不同品牌的(de)(de)(de)(de)硅(gui)酮(tong)(tong)膠(jiao)，致(zhi)使(shi)價(jia)(jia)格大跌。現在(zai)，在(zai)購買鋁(lv)(lv)塑板(ban)(ban)的(de)(de)(de)(de)時候(hou)，銷售商會推薦那(nei)種(zhong)(zhong)專用(yong)的(de)(de)(de)(de)快干膠(jiao)。這(zhe)種(zhong)(zhong)膠(jiao)在(zai)室(shi)內使(shi)用(yong)尚可，用(yong)在(zai)氣候(hou)變化無常(chang)的(de)(de)(de)(de)室(shi)外，便出現板(ban)(ban)材開(kai)膠(jiao)、脫落的(de)(de)(de)(de)現象(xiang)。

三、鋁塑板(ban)表面的變形、起鼓

隨(sui)便在哪個城市中逛上(shang)(shang)一圈，都不難發現(xian)一些鋁塑板表面(mian)(mian)變形、起鼓(gu)的(de)(de)(de)那(nei)些大(da)煞風景的(de)(de)(de)工(gong)(gong)(gong)程。小(xiao)(xiao)小(xiao)(xiao)的(de)(de)(de)門面(mian)(mian)裝修(xiu)工(gong)(gong)(gong)程上(shang)(shang)這(zhe)種現(xian)象，大(da)型高層(ceng)建筑上(shang)(shang)也有這(zhe)種現(xian)象。以前在施(shi)工(gong)(gong)(gong)中，出現(xian)過(guo)這(zhe)種質量問(wen)題，我們曾認為(wei)是(shi)(shi)板材(cai)(cai)本身的(de)(de)(de)質量原(yuan)因;后(hou)來，經(jing)過(guo)大(da)家(jia)的(de)(de)(de)集中分(fen)析才(cai)發現(xian)，主(zhu)要問(wen)題出在粘貼鋁塑板的(de)(de)(de)基層(ceng)板材(cai)(cai)上(shang)(shang)，其次才(cai)是(shi)(shi)鋁塑板本身的(de)(de)(de)質量問(wen)題。經(jing)銷商經(jing)常給(gei)我們提供鋁塑板的(de)(de)(de)施(shi)工(gong)(gong)(gong)工(gong)(gong)(gong)藝，其推(tui)薦使用(yong)(yong)的(de)(de)(de)基層(ceng)材(cai)(cai)料主(zhu)要是(shi)(shi)高密度(du)板、木工(gong)(gong)(gong)板之(zhi)類。其實，這(zhe)類材(cai)(cai)料在室(shi)(shi)外使用(yong)(yong)時，其使用(yong)(yong)壽命是(shi)(shi)很(hen)脆弱的(de)(de)(de)，經(jing)過(guo)風吹、日曬、雨(yu)淋后(hou)，必然會(hui)產(chan)生變形。既(ji)然基層(ceng)材(cai)(cai)料都變形了，那(nei)么作為(wei)面(mian)(mian)層(ceng)的(de)(de)(de)鋁塑板那(nei)有不變形之(zhi)理(li)?可見(jian)，理(li)想的(de)(de)(de)室(shi)(shi)外基層(ceng)材(cai)(cai)料應(ying)經(jing)過(guo)防銹處理(li)后(hou)角鋼、方鋼管結成(cheng)骨(gu)架(jia)為(wei)佳(jia)。如果條件允許的(de)(de)(de)話，采用(yong)(yong)鋁型材(cai)(cai)作為(wei)骨(gu)架(jia)就更為(wei)理(li)想了。這(zhe)類金(jin)屬材(cai)(cai)料制作的(de)(de)(de)骨(gu)架(jia)，其成(cheng)本并(bing)不比(bi)木龍骨(gu)、高密板高出許多，可確實保(bao)證了工(gong)(gong)(gong)程質量。

四、鋁塑板(ban)膠縫(feng)整齊

鋁塑板在裝修建筑物表面(mian)時(shi)(shi)，板塊之(zhi)間(jian)一般都有一定(ding)寬度(du)的(de)(de)(de)縫隙。為(wei)了美觀的(de)(de)(de)需要，一般都要在縫隙中充(chong)填(tian)黑色的(de)(de)(de)密封膠。在打膠時(shi)(shi)有些(xie)施工人員為(wei)了省時(shi)(shi)的(de)(de)(de)需要，不用(yong)紙膠帶(dai)來(lai)保證打膠的(de)(de)(de)整齊、規矩，而(er)是(shi)利用(yong)鋁塑板表面(mian)的(de)(de)(de)保護(hu)膜(mo)作為(wei)替代(dai)品(pin)。由于(yu)鋁塑板在切割時(shi)(shi)，保護(hu)膜(mo)會產生不同程度(du)的(de)(de)(de)撕裂情況，所(suo)以用(yong)它(ta)來(lai)做保護(hu)膠帶(dai)的(de)(de)(de)替代(dai)品(pin)，不可能(neng)把膠縫收拾(shi)得(de)整整齊齊。
