不銹鋼瓦楞形(xing)板(ban)是不銹鋼寬幅(fu)型鋼的一種，由于(yu)其形(xing)狀(zhuang)如同頂上用瓦片鋪(pu)成的行列隆(long)起部(bu)分，故稱為(wei)香蕉視頻app下載蘋果版:不銹鋼瓦楞形板，如圖5-37所(suo)示。
人們過去常見(jian)的“瓦楞（形(xing)(xing)）板(ban)(ban)”大都(dou)是(shi)用普通低碳鋼，也就是(shi)非合(he)金鋼材(cai)(cai)(cai)料(liao)制(zhi)成的（見(jian)圖5-38),還有用非金屬材(cai)(cai)(cai)料(liao)如石(shi)棉(mian)、塑料(liao)、紙板(ban)(ban)等制(zhi)成的瓦楞形(xing)(xing)板(ban)(ban)。這些瓦楞形(xing)(xing)板(ban)(ban)主(zhu)要(yao)用于建筑領(ling)域的屋頂材(cai)(cai)(cai)料(liao)、外墻材(cai)(cai)(cai)料(liao)和(he)各(ge)種(zhong)包(bao)裝箱(xiang)體的外形(xing)(xing)材(cai)(cai)(cai)料(liao)和(he)產品包(bao)裝箱(xiang)、盒(he)等，之所以做成瓦楞形(xing)(xing)狀，主(zhu)要(yao)目的是(shi)增加結(jie)構剛度和(he)穩(wen)定性。因此，其(qi)尺寸精(jing)度和(he)表面(mian)質量要(yao)求(qiu)及材(cai)(cai)(cai)質要(yao)求(qiu)都(dou)不是(shi)很高。
此處介紹的(de)(de)(de)(de)不(bu)(bu)銹(xiu)鋼(gang)(gang)(gang)瓦(wa)(wa)(wa)楞(leng)(leng)(leng)形(xing)(xing)(xing)板(ban)(ban)與普(pu)通(tong)(tong)的(de)(de)(de)(de)“瓦(wa)(wa)(wa)楞(leng)(leng)(leng)（形(xing)(xing)(xing)）板(ban)(ban)”有著(zhu)本質的(de)(de)(de)(de)不(bu)(bu)同，首(shou)先材料是不(bu)(bu)銹(xiu)鋼(gang)(gang)(gang)，無疑(yi)要(yao)比普(pu)通(tong)(tong)的(de)(de)(de)(de)“瓦(wa)(wa)(wa)楞(leng)(leng)(leng)（形(xing)(xing)(xing)）板(ban)(ban)”具(ju)(ju)有更高(gao)的(de)(de)(de)(de)強度、良好的(de)(de)(de)(de)耐(nai)(nai)腐(fu)蝕性(xing)(xing)(xing)能(neng)(neng)(neng)和極(ji)好的(de)(de)(de)(de)裝飾效果，另外(wai)在結構(gou)上(shang)也大(da)不(bu)(bu)相同。這些都賦予了不(bu)(bu)銹(xiu)鋼(gang)(gang)(gang)瓦(wa)(wa)(wa)楞(leng)(leng)(leng)形(xing)(xing)(xing)板(ban)(ban)不(bu)(bu)僅(jin)具(ju)(ju)有普(pu)通(tong)(tong)“瓦(wa)(wa)(wa)楞(leng)(leng)(leng)形(xing)(xing)(xing)板(ban)(ban)”的(de)(de)(de)(de)各種功能(neng)(neng)(neng)與作用(yong)，而且具(ju)(ju)有普(pu)通(tong)(tong)“瓦(wa)(wa)(wa)楞(leng)(leng)(leng)（形(xing)(xing)(xing)）板(ban)(ban)”沒有的(de)(de)(de)(de)功能(neng)(neng)(neng)，即不(bu)(bu)銹(xiu)鋼(gang)(gang)(gang)瓦(wa)(wa)(wa)楞(leng)(leng)(leng)形(xing)(xing)(xing)板(ban)(ban)可以(yi)作為傳熱元(yuan)件使(shi)用(yong)。作為傳熱元(yuan)件，對其(qi)各方(fang)面(mian)(mian)的(de)(de)(de)(de)要(yao)求(qiu)就(jiu)比普(pu)通(tong)(tong)“瓦(wa)(wa)(wa)楞(leng)(leng)(leng)（形(xing)(xing)(xing)）板(ban)(ban)”高(gao)得多，特(te)別是對瓦(wa)(wa)(wa)楞(leng)(leng)(leng)形(xing)(xing)(xing)板(ban)(ban)表觀的(de)(de)(de)(de)要(yao)求(qiu)。對瓦(wa)(wa)(wa)楞(leng)(leng)(leng)形(xing)(xing)(xing)板(ban)(ban)表觀的(de)(de)(de)(de)要(yao)求(qiu)主(zhu)要(yao)體現在對外(wai)形(xing)(xing)(xing)尺(chi)寸和表面(mian)(mian)質量(liang)的(de)(de)(de)(de)要(yao)求(qiu)上(shang)。因此，采(cai)用(yong)何種方(fang)式、何種工藝加(jia)工生產不(bu)(bu)銹(xiu)鋼(gang)(gang)(gang)瓦(wa)(wa)(wa)楞(leng)(leng)(leng)形(xing)(xing)(xing)板(ban)(ban)就(jiu)成為保證其(qi)外(wai)形(xing)(xing)(xing)尺(chi)寸和質量(liang)的(de)(de)(de)(de)關鍵。其(qi)他性(xing)(xing)(xing)能(neng)(neng)(neng)（機械性(xing)(xing)(xing)能(neng)(neng)(neng)、耐(nai)(nai)腐(fu)蝕性(xing)(xing)(xing)能(neng)(neng)(neng)和焊接(jie)性(xing)(xing)(xing)能(neng)(neng)(neng)）主(zhu)要(yao)取決(jue)于(yu)所選用(yong)的(de)(de)(de)(de)材料。
1. 不(bu)銹鋼(gang)瓦楞形板外形尺(chi)寸
從圖5-37和(he)圖5-39可(ke)以(yi)看(kan)出不銹(xiu)鋼瓦楞(leng)形板的(de)外表形狀(zhuang)是(shi)有規(gui)律、周(zhou)期性變(bian)化的(de)，而且彎曲深度(du)較小、形狀(zhuang)單一，不僅(jin)有橫(heng)向波(bo)(bo)紋(wen)，而且還(huan)有縱(zong)向波(bo)(bo)紋(wen)。所以(yi)說，其形狀(zhuang)既簡(jian)單又復雜(za)，簡(jian)單是(shi)指(zhi)形狀(zhuang)單一，有規(gui)律；復雜(za)是(shi)指(zhi)不僅(jin)有橫(heng)向波(bo)(bo)紋(wen)，而且還(huan)有縱(zong)向波(bo)(bo)紋(wen)。這(zhe)就(jiu)給(gei)不銹(xiu)鋼瓦楞(leng)形板的(de)成型(xing)(xing)帶來(lai)不小的(de)難度(du)，在(zai)成型(xing)(xing)工藝(yi)上必須采取相應的(de)工藝(yi)措施和(he)手段(duan)，方能(neng)保證獲得要(yao)求的(de)外形尺(chi)寸和(he)成型(xing)(xing)質量。
圖5-39是不銹鋼瓦楞(leng)(leng)形(xing)板(ban)的實物照(zhao)片，從圖片可(ke)以看出(chu)，不銹鋼瓦楞(leng)(leng)形(xing)板(ban)的外表和(he)形(xing)狀是非常美(mei)觀、漂亮的，具有較高的觀賞性(xing)，如同(tong)工藝(yi)品、裝飾品。

3. 縱向波紋的成型
縱向(xiang)(xiang)波紋(wen)(wen)(wen)的成(cheng)型(xing)(xing)(xing)是在橫向(xiang)(xiang)波紋(wen)(wen)(wen)成(cheng)型(xing)(xing)(xing)之后的橫向(xiang)(xiang)波紋(wen)(wen)(wen)上(shang)成(cheng)型(xing)(xing)(xing)的。所(suo)以在已成(cheng)型(xing)(xing)(xing)的波紋(wen)(wen)(wen)上(shang)再成(cheng)型(xing)(xing)(xing)縱向(xiang)(xiang)波紋(wen)(wen)(wen)是有難度(du)的。其(qi)難度(du)主要(yao)表現為，可能破(po)壞(huai)已成(cheng)型(xing)(xing)(xing)的橫向(xiang)(xiang)波紋(wen)(wen)(wen)，而且縱向(xiang)(xiang)波紋(wen)(wen)(wen)也(ye)成(cheng)型(xing)(xing)(xing)不好。選用何種(zhong)方式成(cheng)型(xing)(xing)(xing)就(jiu)成(cheng)為縱向(xiang)(xiang)波紋(wen)(wen)(wen)成(cheng)型(xing)(xing)(xing)的關鍵。
