熱鍍鋅鋼管批發熱鍍鋅卷板現貨消息：熱鍍鋅產品廣泛用于建筑、家電、車船、容器制造業、機電業等，幾乎涉及到衣食住行各個領域。近年來，世界鍍鋅鋼板需求量不斷增加，產量增長也很快，在美、日等鋼材生產大國，熱鍍鋅鋼板在鋼材中所占比例已高達13%-15%。攀鋼熱鍍鋅鋼管批發 熱鍍鋅卷板(ban)現貨消(xiao)息：近(jin)來，汽車行(xing)業越來越重視材(cai)料的使(shi)用壽命，用涂漆冷(leng)軋鋼板(ban)已不(bu)能滿足耐腐蝕(shi)方面的要求。在這(zhe)種情況(kuang)下，耐腐蝕(shi)性優(you)良且成本低(di)廉(lian)的熱鍍鋅板(ban)開始普遍受到了汽車廠家(jia)的青睞。

重慶(qing)樓(lou)(lou)承板(ban)(ban)的(de)(de)鍍(du)(du)鋅量沒有(you)一個具(ju)體的(de)(de)標準(zhun)，制作壓型鋼(gang)(gang)(gang)板(ban)(ban)的(de)(de)冷軋鋼(gang)(gang)(gang)卷須連續(xu)熱浸鍍(du)(du)鋅（或鍍(du)(du)鋁(lv)(lv)鋅），鍍(du)(du)（鋁(lv)(lv)）鋅量視設計要求而(er)定。樓(lou)(lou)承板(ban)(ban)用(yong)壓型鋼(gang)(gang)(gang)板(ban)(ban)宜選(xuan)擇(ze)熱浸鍍(du)(du)鋅鋼(gang)(gang)(gang)板(ban)(ban)。不允(yun)許使(shi)用(yong)電鍍(du)(du)鋅鋼(gang)(gang)(gang)板(ban)(ban)，電鍍(du)(du)鋅鋼(gang)(gang)(gang)板(ban)(ban)僅在基材表面(mian)形成保護層(ceng)，防(fang)(fang)腐能(neng)力有(you)限。目前市場上有(you)鍍(du)(du)鋅鋼(gang)(gang)(gang)板(ban)(ban)（鍍(du)(du)層(ceng)含鋁(lv)(lv)5%或55%），在酸性(xing)環境(jing)下的(de)(de)防(fang)(fang)腐效果由(you)于熱浸鍍(du)(du)鋅鋼(gang)(gang)(gang)板(ban)(ban)，但在混凝土的(de)(de)堿性(xing)條(tiao)件(jian)下，鍍(du)(du)鋁(lv)(lv)鋅的(de)(de)防(fang)(fang)腐蝕(shi)性(xing)能(neng)低于熱浸鍍(du)(du)鋅鋼(gang)(gang)(gang)板(ban)(ban)，且鋁(lv)(lv)會(hui)和混凝土發生(sheng)反應，并降低混凝土與鋼(gang)(gang)(gang)板(ban)(ban)的(de)(de)粘(zhan)結(jie)性(xing)能(neng)。因此參考國(guo)外規(gui)范，及國(guo)內外工程，行家壓型鋼(gang)(gang)(gang)板(ban)(ban)不建(jian)議使(shi)用(yong)鍍(du)(du)鋁(lv)(lv)鋅鋼(gang)(gang)(gang)板(ban)(ban)。

鍍鋅板開(kai)平的整個(ge)(ge)生產來說它(ta)(ta)首(shou)先就是(shi)(shi)(shi)要(yao)達到(dao)很(hen)高(gao)的工(gong)藝，但是(shi)(shi)(shi)如果(guo)(guo)要(yao)讓(rang)(rang)它(ta)(ta)在(zai)自(zi)(zi)(zi)己(ji)(ji)(ji)的工(gong)藝性上(shang)面(mian)(mian)達到(dao)很(hen)高(gao)的表現(xian)，也(ye)是(shi)(shi)(shi)要(yao)讓(rang)(rang)它(ta)(ta)達到(dao)很(hen)高(gao)的要(yao)求(qiu)的，那(nei)么(me)它(ta)(ta)在(zai)自(zi)(zi)(zi)己(ji)(ji)(ji)工(gong)藝性上(shang)面(mian)(mian)都(dou)是(shi)(shi)(shi)要(yao)達到(dao)什么(me)樣(yang)的要(yao)求(qiu)呢？首(shou)先一(yi)個(ge)(ge)方(fang)面(mian)(mian)，就是(shi)(shi)(shi)它(ta)(ta)在(zai)自(zi)(zi)(zi)己(ji)(ji)(ji)的生產上(shang)面(mian)(mian)要(yao)讓(rang)(rang)自(zi)(zi)(zi)己(ji)(ji)(ji)有(you)很(hen)高(gao)的技術，如果(guo)(guo)是(shi)(shi)(shi)一(yi)個(ge)(ge)廠家(jia)，他(ta)(ta)們沒(mei)有(you)很(hen)高(gao)的技術，那(nei)么(me)他(ta)(ta)們是(shi)(shi)(shi)不能讓(rang)(rang)自(zi)(zi)(zi)己(ji)(ji)(ji)的工(gong)藝性有(you)很(hen)好的表現(xian)的。鍍鋅板開(kai)平的整個(ge)(ge)設備上(shang)面(mian)(mian)也(ye)是(shi)(shi)(shi)很(hen)重要(yao)的，現(xian)在(zai)也(ye)有(you)一(yi)些(xie)廠家(jia)，他(ta)(ta)們因為自(zi)(zi)(zi)己(ji)(ji)(ji)沒(mei)有(you)很(hen)好的實力，所以自(zi)(zi)(zi)然就會讓(rang)(rang)它(ta)(ta)在(zai)自(zi)(zi)(zi)己(ji)(ji)(ji)的設備上(shang)面(mian)(mian)的下(xia)降，如果(guo)(guo)是(shi)(shi)(shi)一(yi)些(xie)大廠家(jia)來說，他(ta)(ta)們在(zai)自(zi)(zi)(zi)己(ji)(ji)(ji)的整個(ge)(ge)工(gong)作中，都(dou)是(shi)(shi)(shi)能使用到(dao)電腦上(shang)面(mian)(mian)的控(kong)制，但是(shi)(shi)(shi)對于有(you)些(xie)廠家(jia)來說，他(ta)(ta)們還在(zai)使用一(yi)些(xie)落后的設備，這樣(yang)自(zi)(zi)(zi)然就會讓(rang)(rang)它(ta)(ta)在(zai)工(gong)藝性上(shang)面(mian)(mian)下(xia)降，所以這一(yi)點也(ye)是(shi)(shi)(shi)它(ta)(ta)在(zai)自(zi)(zi)(zi)己(ji)(ji)(ji)工(gong)藝性上(shang)面(mian)(mian)的一(yi)些(xie)條件。

首先，在(zai)鋼結構樓層板(ban)(ban)(ban)(ban)(ban)(ban)中(zhong)要(yao)(yao)達到耐火1.5小時(shi)，總的(de)(de)來說(shuo)可(ke)以(yi)選擇(ze)開口(kou)(kou)(kou)板(ban)(ban)(ban)(ban)(ban)(ban)、縮口(kou)(kou)(kou)板(ban)(ban)(ban)(ban)(ban)(ban)、閉(bi)口(kou)(kou)(kou)板(ban)(ban)(ban)(ban)(ban)(ban)三大類(lei)。規范上(shang)混凝(ning)土要(yao)(yao)高于(yu)(yu)開口(kou)(kou)(kou)板(ban)(ban)(ban)(ban)(ban)(ban)肋(lei)頂(ding)之上(shang)80mm，并且板(ban)(ban)(ban)(ban)(ban)(ban)底(di)(di)需(xu)(xu)配置板(ban)(ban)(ban)(ban)(ban)(ban)底(di)(di)受(shou)力(li)筋(jin)。還有(you)一種就是再開口(kou)(kou)(kou)板(ban)(ban)(ban)(ban)(ban)(ban)底(di)(di)部(bu)刷防火涂料，涂料厚度大于(yu)(yu)等(deng)于(yu)(yu)15,這(zhe)樣的(de)(de)話，只要(yao)(yao)達到構造要(yao)(yao)求高于(yu)(yu)肋(lei)頂(ding)5公分就可(ke)以(yi)了。而(er)縮口(kou)(kou)(kou)板(ban)(ban)(ban)(ban)(ban)(ban)和閉(bi)口(kou)(kou)(kou)板(ban)(ban)(ban)(ban)(ban)(ban)，只需(xu)(xu)要(yao)(yao)總的(de)(de)樓板(ban)(ban)(ban)(ban)(ban)(ban)厚度大于(yu)(yu)等(deng)于(yu)(yu)110即可(ke)，但是縮口(kou)(kou)(kou)板(ban)(ban)(ban)(ban)(ban)(ban)雖然(ran)在(zai)防火方面比開口(kou)(kou)(kou)板(ban)(ban)(ban)(ban)(ban)(ban)要(yao)(yao)好。但是底(di)(di)部(bu)還是需(xu)(xu)要(yao)(yao)加板(ban)(ban)(ban)(ban)(ban)(ban)底(di)(di)受(shou)力(li)筋(jin)，而(er)閉(bi)口(kou)(kou)(kou)板(ban)(ban)(ban)(ban)(ban)(ban)則不需(xu)(xu)要(yao)(yao)。
