雙曲鋁單板作為鋁單板大軍中的獨特一員，有著其獨特的作用。雙曲鋁單板由(you)于(yu)其外觀具有(you)弧度(du)的(de)特(te)殊性，有(you)別于(yu)一(yi)般(ban)的(de)平板(ban)型鋁(lv)單(dan)(dan)板(ban)，而更多(duo)地被(bei)應(ying)用(yong)在(zai)建筑特(te)殊外觀設(she)計，室內(nei)裝飾燈(deng)用(yong)途。那雙曲鋁(lv)單(dan)(dan)板(ban)的(de)加工過(guo)程是怎樣的(de)呢？對比一(yi)般(ban)平板(ban)鋁(lv)單(dan)(dan)板(ban)的(de)加工有(you)什(shen)么(me)特(te)殊的(de)要求(qiu)？

　　雙曲鋁(lv)(lv)(lv)單板(ban)(ban)加(jia)(jia)(jia)工步驟(zou)主(zhu)要分(fen)兩部分(fen)，第一(yi)部分(fen)是(shi)鈑(ban)金(jin)加(jia)(jia)(jia)工。鈑(ban)金(jin)加(jia)(jia)(jia)工主(zhu)要針對雙曲鋁(lv)(lv)(lv)單板(ban)(ban)的外觀(guan)，尺寸(cun)等(deng)“大方向”的加(jia)(jia)(jia)工，加(jia)(jia)(jia)工過程是(shi)用裁(cai)剪、折邊、彎弧、焊接、打磨(mo)等(deng)工序，把鋁(lv)(lv)(lv)單板(ban)(ban)加(jia)(jia)(jia)工成施工所需的形狀和尺寸(cun)，該部分(fen)工序決定了鋁(lv)(lv)(lv)單板(ban)(ban)弧度，外觀(guan)等(deng)重(zhong)要參數。

　　第二部分的(de)(de)工(gong)藝就是噴(pen)(pen)(pen)涂。噴(pen)(pen)(pen)涂就是在(zai)加工(gong)好(hao)的(de)(de)鋁(lv)(lv)板上噴(pen)(pen)(pen)涂油漆。噴(pen)(pen)(pen)涂分為(wei)兩(liang)種(zhong)(zhong)，一(yi)種(zhong)(zhong)是人工(gong)噴(pen)(pen)(pen)涂，一(yi)種(zhong)(zhong)是機器噴(pen)(pen)(pen)涂。機器噴(pen)(pen)(pen)涂一(yi)般只適合規則的(de)(de)平板，但這種(zhong)(zhong)鋁(lv)(lv)單板在(zai)實(shi)際的(de)(de)使用(yong)中用(yong)的(de)(de)比較少，國內(nei)大部分廠(chang)家采(cai)用(yong)的(de)(de)人工(gong)噴(pen)(pen)(pen)涂。人工(gong)噴(pen)(pen)(pen)涂的(de)(de)一(yi)大優(you)點就是不管量的(de)(de)大小，顏色都可以任選。噴(pen)(pen)(pen)涂前(qian)需要對雙(shuang)曲(qu)鋁(lv)(lv)單板進行噴(pen)(pen)(pen)涂前(qian)處理，到達(da)最(zui)好(hao)的(de)(de)結果。

　　雙(shuang)曲(qu)鋁(lv)單(dan)(dan)板在噴(pen)涂錢必須要(yao)進行一些必要(yao)的處理才能保證雙(shuang)曲(qu)鋁(lv)單(dan)(dan)板噴(pen)涂的質量。雙(shuang)曲(qu)鋁(lv)單(dan)(dan)板噴(pen)涂前(qian)處理的目的是(shi)清洗掉鋁(lv)合(he)金基(ji)材(cai)上(shang)面的油污，使(shi)噴(pen)涂材(cai)料更好地粘附(fu)在鋁(lv)合(he)金表面上(shang)。

　　雙(shuang)(shuang)曲(qu)(qu)鋁(lv)(lv)單(dan)(dan)板(ban)噴涂的(de)(de)(de)前處(chu)理過(guo)程第(di)一(yi)步(bu)是(shi)用(yong)(yong)(yong)清(qing)(qing)(qing)(qing)(qing)(qing)(qing)水(shui)沖洗(xi)(xi)，把雙(shuang)(shuang)曲(qu)(qu)鋁(lv)(lv)單(dan)(dan)板(ban)基(ji)(ji)(ji)(ji)(ji)材(cai)上(shang)面的(de)(de)(de)灰塵全部清(qing)(qing)(qing)(qing)(qing)(qing)(qing)除干凈，第(di)二(er)步(bu)用(yong)(yong)(yong)堿水(shui)再(zai)(zai)(zai)次清(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)雙(shuang)(shuang)曲(qu)(qu)鋁(lv)(lv)單(dan)(dan)板(ban)基(ji)(ji)(ji)(ji)(ji)材(cai)，堿性(xing)物(wu)質能有(you)效地(di)溶(rong)解雙(shuang)(shuang)曲(qu)(qu)鋁(lv)(lv)單(dan)(dan)板(ban)基(ji)(ji)(ji)(ji)(ji)材(cai)上(shang)面的(de)(de)(de)各種(zhong)油脂，補充(chong)清(qing)(qing)(qing)(qing)(qing)(qing)(qing)潔(jie)清(qing)(qing)(qing)(qing)(qing)(qing)(qing)水(shui)不能去掉的(de)(de)(de)污跡；第(di)三步(bu)再(zai)(zai)(zai)用(yong)(yong)(yong)清(qing)(qing)(qing)(qing)(qing)(qing)(qing)水(shui)把殘留(liu)的(de)(de)(de)堿性(xing)物(wu)質清(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)掉，為下一(yi)步(bu)工序做好準備(bei)；第(di)四步(bu)使用(yong)(yong)(yong)酸(suan)性(xing)溶(rong)液對雙(shuang)(shuang)曲(qu)(qu)鋁(lv)(lv)單(dan)(dan)板(ban)基(ji)(ji)(ji)(ji)(ji)材(cai)再(zai)(zai)(zai)次清(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)，目(mu)的(de)(de)(de)在于清(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)雙(shuang)(shuang)曲(qu)(qu)鋁(lv)(lv)單(dan)(dan)板(ban)基(ji)(ji)(ji)(ji)(ji)材(cai)表面上(shang)與酸(suan)性(xing)溶(rong)液發生化(hua)(hua)(hua)學反應(ying)的(de)(de)(de)殘留(liu)物(wu)，第(di)五步(bu)用(yong)(yong)(yong)清(qing)(qing)(qing)(qing)(qing)(qing)(qing)水(shui)對雙(shuang)(shuang)曲(qu)(qu)鋁(lv)(lv)單(dan)(dan)板(ban)基(ji)(ji)(ji)(ji)(ji)材(cai)進(jin)行(xing)再(zai)(zai)(zai)次清(qing)(qing)(qing)(qing)(qing)(qing)(qing)潔(jie)，第(di)六(liu)步(bu)對雙(shuang)(shuang)曲(qu)(qu)鋁(lv)(lv)單(dan)(dan)板(ban)基(ji)(ji)(ji)(ji)(ji)材(cai)進(jin)行(xing)鉻化(hua)(hua)(hua)處(chu)理，第(di)七部用(yong)(yong)(yong)清(qing)(qing)(qing)(qing)(qing)(qing)(qing)水(shui)對鉻化(hua)(hua)(hua)后(hou)(hou)的(de)(de)(de)雙(shuang)(shuang)曲(qu)(qu)鋁(lv)(lv)單(dan)(dan)板(ban)基(ji)(ji)(ji)(ji)(ji)材(cai)進(jin)行(xing)最后(hou)(hou)的(de)(de)(de)清(qing)(qing)(qing)(qing)(qing)(qing)(qing)洗(xi)(xi)。

　　雙曲鋁(lv)單(dan)(dan)板(ban)噴涂的(de)前處(chu)理主(zhu)要(yao)是對雙曲鋁(lv)單(dan)(dan)板(ban)基材(cai)進行(xing)(xing)各種物質(zhi)的(de)清(qing)洗，然后(hou)進行(xing)(xing)鉻化處(chu)理。其(qi)中(zhong)要(yao)分別(bie)用酸堿(jian)性(xing)溶液對雙曲鋁(lv)單(dan)(dan)板(ban)基材(cai)進行(xing)(xing)沖洗，徹底清(qing)除其(qi)表(biao)面的(de)各種頑固污跡，期間(jian)使用清(qing)水對每個(ge)清(qing)洗步驟進行(xing)(xing)隔開，保持雙曲鋁(lv)單(dan)(dan)板(ban)基材(cai)清(qing)洗各個(ge)工(gong)序的(de)獨立(li)性(xing)。經(jing)過整整七(qi)個(ge)清(qing)洗步驟后(hou)，經(jing)檢驗清(qing)洗質(zhi)量達到標準后(hou)，才能進行(xing)(xing)下(xia)一步的(de)噴涂工(gong)作。

　　經過鈑金加工和噴漆兩部分的工藝后，雙曲鋁單板產品的生產工藝就已經完成，由于雙曲(qu)(qu)鋁(lv)單(dan)板的制(zhi)作工藝技(ji)術要(yao)求較(jiao)高，因此(ci)必須要(yao)有(you)經驗(yan)豐富的技(ji)術員進(jin)行操作，否則容易造成設計(ji)上的誤差而影響雙曲(qu)(qu)鋁(lv)單(dan)板質量(liang)。
