熱鍍鋅價格鍍鋅是一種經常采用的經濟而有效的防腐方法。鋅產量的一半左右均用于此種工藝。鍍鋅卷是為防止鋼板表面遭受腐蝕延長其使用壽命，在鋼板表面涂以一層金屬鋅，這種涂鋅的鋼板稱為鍍鋅卷。昭通熱鍍鋅鍍鋅(xin)卷(juan)(juan)主要用(yong)于建筑、家(jia)(jia)電、汽(qi)車、容器、交通及家(jia)(jia)業(ye)(ye)等領域(yu)。特別是鋼(gang)結(jie)構建筑、汽(qi)車制造、鋼(gang)板(ban)倉制造等行業(ye)(ye)。耐腐(fu)蝕強、表面質(zhi)量好、得利(li)于深加工、經濟實(shi)用(yong)等。有關產(chan)品標準(zhun)都列明鍍鋅(xin)卷(juan)(juan)推薦的標準(zhun)厚度(du)(du)、長(chang)度(du)(du)和寬(kuan)度(du)(du)及其允許(xu)偏差(cha)。鍍鋅(xin)卷(juan)(juan)厚度(du)(du)偏差(cha)一般在(zai)0.05mm，長(chang)寬(kuan)偏差(cha)一般在(zai)5mm ，板(ban)材的厚度(du)(du)一般在(zai)0.2-3.2之間(jian) 。

堆(dui)積樓(lou)承(cheng)(cheng)(cheng)板(ban)(ban)(ban)的(de)地坪應(ying)(ying)基(ji)本(ben)平(ping)坦(tan)，鋼(gang)筋桁(heng)架樓(lou)承(cheng)(cheng)(cheng)板(ban)(ban)(ban)堆(dui)積不(bu)(bu)宜過高，每(mei)堆(dui)不(bu)(bu)超(chao)越60張。樓(lou)承(cheng)(cheng)(cheng)板(ban)(ban)(ban)運至現場，需妥(tuo)善保(bao)護，不(bu)(bu)得(de)有(you)任何損壞和(he)污(wu)染，特別(bie)不(bu)(bu)得(de)感染油污(wu)。樓(lou)承(cheng)(cheng)(cheng)板(ban)(ban)(ban)應(ying)(ying)根據排版圖預先切開(kai)、編號。起(qi)吊(diao)前，每(mei)捆要(yao)有(you)兩條鋼(gang)絲繩，分別(bie)捆于兩頭四分之一(yi)鋼(gang)板(ban)(ban)(ban)長度處，采用專用吊(diao)具吊(diao)起(qi)。應(ying)(ying)先行試(shi)吊(diao)，檢查重心是否(fou)(fou)穩定，鋼(gang)索是否(fou)(fou)會(hui)滑動，待牢靠(kao)，無慮時(shi)方可吊(diao)起(qi)。起(qi)吊(diao)時(shi)，應(ying)(ying)從下往上樓(lou)層(ceng)次序(xu)吊(diao)料(liao)為(wei)原則(ze)，避(bi)免(mian)因(yin)(yin)先行吊(diao)放上層(ceng)資料(liao)后，阻止下面樓(lou)層(ceng)的(de)吊(diao)放作業。整疊樓(lou)承(cheng)(cheng)(cheng)板(ban)(ban)(ban)放梁面時(shi)，應(ying)(ying)考(kao)慮梁的(de)承(cheng)(cheng)(cheng)載能力(li)，避(bi)免(mian)因(yin)(yin)集中載荷過大(da)，造成梁的(de)變(bian)形。樓(lou)承(cheng)(cheng)(cheng)板(ban)(ban)(ban)吊(diao)至樓(lou)層(ceng)，暫時(shi)不(bu)(bu)鋪設時(shi)，應(ying)(ying)作牢靠(kao)固(gu)定，避(bi)免(mian)飛落和(he)滑落傷人。

熱(re)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)板和電鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)板在鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)量(liang)上有很大的(de)(de)差別，就像山(shan)東彩(cai)涂卷）。熱(re)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)的(de)(de)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)量(liang)不(bu)可能太小，一般(ban)較小為(wei)雙面(mian)50～60g／m2，較大可達(da)600g／m2。電鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)板的(de)(de)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)層可以很薄，較小達(da)15g／m2，但要求鍍(du)(du)(du)(du)層較厚(hou)的(de)(de)話則(ze)生產線速度很慢(man)，不(bu)適應現代化(hua)機組(zu)的(de)(de)工藝特點，一般(ban)較大為(wei)lO0g／m2左右(you)。正因為(wei)如此，電鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)板的(de)(de)生產受到很大的(de)(de)限(xian)制(zhi)。工一般(ban)電鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)比較多，適用(yong)于小部件(jian)(jian)；熱(re)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)一般(ban)用(yong)于電力設備(bei)和構件(jian)(jian)，適用(yong)于大的(de)(de)部件(jian)(jian)和設備(bei)。當(dang)然他們的(de)(de)價(jia)格也相對便(bian)宜一些。建設部已(yi)正式下文，淘汰(tai)技術落后的(de)(de)冷鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)管(guan)，不(bu)準用(yong)冷鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)管(guan)作水(shui)、煤氣管(guan)。

首先(xian)，在鋼(gang)結(jie)構樓(lou)層板(ban)(ban)(ban)(ban)(ban)(ban)中要(yao)(yao)達到耐火(huo)1.5小時，總(zong)的來說可(ke)以(yi)選擇開(kai)口(kou)板(ban)(ban)(ban)(ban)(ban)(ban)、縮口(kou)板(ban)(ban)(ban)(ban)(ban)(ban)、閉口(kou)板(ban)(ban)(ban)(ban)(ban)(ban)三大類。規(gui)范上(shang)混凝土要(yao)(yao)高于(yu)(yu)開(kai)口(kou)板(ban)(ban)(ban)(ban)(ban)(ban)肋(lei)頂之上(shang)80mm，并且板(ban)(ban)(ban)(ban)(ban)(ban)底(di)需(xu)配(pei)置(zhi)板(ban)(ban)(ban)(ban)(ban)(ban)底(di)受(shou)(shou)力(li)筋(jin)。還(huan)有(you)一(yi)種就(jiu)是(shi)(shi)再開(kai)口(kou)板(ban)(ban)(ban)(ban)(ban)(ban)底(di)部刷(shua)防火(huo)涂料(liao)，涂料(liao)厚度大于(yu)(yu)等于(yu)(yu)15,這樣的話，只要(yao)(yao)達到構造要(yao)(yao)求高于(yu)(yu)肋(lei)頂5公分(fen)就(jiu)可(ke)以(yi)了。而縮口(kou)板(ban)(ban)(ban)(ban)(ban)(ban)和閉口(kou)板(ban)(ban)(ban)(ban)(ban)(ban)，只需(xu)要(yao)(yao)總(zong)的樓(lou)板(ban)(ban)(ban)(ban)(ban)(ban)厚度大于(yu)(yu)等于(yu)(yu)110即可(ke)，但是(shi)(shi)縮口(kou)板(ban)(ban)(ban)(ban)(ban)(ban)雖(sui)然在防火(huo)方面比開(kai)口(kou)板(ban)(ban)(ban)(ban)(ban)(ban)要(yao)(yao)好(hao)。但是(shi)(shi)底(di)部還(huan)是(shi)(shi)需(xu)要(yao)(yao)加板(ban)(ban)(ban)(ban)(ban)(ban)底(di)受(shou)(shou)力(li)筋(jin)，而閉口(kou)板(ban)(ban)(ban)(ban)(ban)(ban)則不需(xu)要(yao)(yao)。

近(jin)期鋼價延續低(di)迷，隨(sui)著通國規模的酷(ku)暑和旱季到來，熱鍍鋅(xin)卷板價格商(shang)場(chang)(chang)逐漸進(jin)入需要旺季，海內鋼鐵商(shang)場(chang)(chang)或將窄幅調(diao)整。在決(jue)策層兩手抓制度措施落實(shi)狀況、貨銀本位度定向(xiang)寬松(song)力度加大的直觀層面利好牽(qian)動下，商(shang)場(chang)(chang)信念逐漸趨穩，短(duan)期海內鋼價無望(wang)止跌(die)企穩;另一上(shang)面，以(yi)后鋼價殺跌(die)電能(neng)有余，而上(shang)漲(zhang)也仍然屏(ping)障(zhang)重重。熱鍍鋅(xin)卷板價格價錢或將長期在于(yu)低(di)位運行場(chang)(chang)面。

彩鋼(gang)(gang)是(shi)(shi)指彩涂(tu)(tu)鋼(gang)(gang)板(ban)(ban)(ban)，彩涂(tu)(tu)鋼(gang)(gang)板(ban)(ban)(ban)是(shi)(shi)一(yi)種帶有(you)(you)有(you)(you)機涂(tu)(tu)層(ceng)的(de)(de)(de)鋼(gang)(gang)板(ban)(ban)(ban)，傳(chuan)統的(de)(de)(de)涂(tu)(tu)層(ceng)分好幾類，氟碳涂(tu)(tu)層(ceng)的(de)(de)(de)，幾乎可(ke)以(yi)(yi)防腐20年。一(yi)般從鋼(gang)(gang)廠以(yi)(yi)卷(juan)筒(tong)的(de)(de)(de)形式分銷到各地。我們經(jing)常看到的(de)(de)(de)彩鋼(gang)(gang)板(ban)(ban)(ban)是(shi)(shi)指加工好的(de)(de)(de)板(ban)(ban)(ban)材(cai)，厚度在(zai)50~100mm左右，它是(shi)(shi)由(you)中(zhong)間(jian)(jian)的(de)(de)(de)填料和兩面的(de)(de)(de)彩鋼(gang)(gang)板(ban)(ban)(ban)組(zu)成。其中(zhong)，彩板(ban)(ban)(ban)厚度有(you)(you)0.4mm、0.5mm、0.6mm等不同的(de)(de)(de)厚度,中(zhong)間(jian)(jian)層(ceng)可(ke)以(yi)(yi)是(shi)(shi)聚胺(an)脂、巖(yan)綿或泡沫(mo)塑料等。由(you)于(yu)有(you)(you)專用型(xing)材(cai)，所以(yi)(yi)用彩鋼(gang)(gang)板(ban)(ban)(ban)構(gou)筑(zhu)的(de)(de)(de)廠房建造速度很快(kuai)（如非典時的(de)(de)(de)小湯山(shan)醫院），但(dan)強度低。
