熱(re)(re)鍍(du)(du)(du)鋅(xin)(xin)板(ban)和電(dian)(dian)鍍(du)(du)(du)鋅(xin)(xin)板(ban)在鍍(du)(du)(du)鋅(xin)(xin)量上有很(hen)大的(de)(de)(de)差別，就像山東彩(cai)涂(tu)卷）。熱(re)(re)鍍(du)(du)(du)鋅(xin)(xin)的(de)(de)(de)鍍(du)(du)(du)鋅(xin)(xin)量不(bu)可能太小(xiao)(xiao)，一(yi)般較(jiao)(jiao)(jiao)(jiao)小(xiao)(xiao)為(wei)雙面50～60g／m2，較(jiao)(jiao)(jiao)(jiao)大可達(da)600g／m2。電(dian)(dian)鍍(du)(du)(du)鋅(xin)(xin)板(ban)的(de)(de)(de)鍍(du)(du)(du)鋅(xin)(xin)層可以很(hen)薄，較(jiao)(jiao)(jiao)(jiao)小(xiao)(xiao)達(da)15g／m2，但要求鍍(du)(du)(du)層較(jiao)(jiao)(jiao)(jiao)厚的(de)(de)(de)話(hua)則(ze)生產(chan)線速(su)度很(hen)慢，不(bu)適(shi)應現代(dai)化機組的(de)(de)(de)工(gong)(gong)藝特點，一(yi)般較(jiao)(jiao)(jiao)(jiao)大為(wei)lO0g／m2左右。正因為(wei)如(ru)此，電(dian)(dian)鍍(du)(du)(du)鋅(xin)(xin)板(ban)的(de)(de)(de)生產(chan)受(shou)到很(hen)大的(de)(de)(de)限制。工(gong)(gong)一(yi)般電(dian)(dian)鍍(du)(du)(du)鋅(xin)(xin)比較(jiao)(jiao)(jiao)(jiao)多(duo)，適(shi)用(yong)于小(xiao)(xiao)部(bu)(bu)件；熱(re)(re)鍍(du)(du)(du)鋅(xin)(xin)一(yi)般用(yong)于電(dian)(dian)力設備(bei)和構件，適(shi)用(yong)于大的(de)(de)(de)部(bu)(bu)件和設備(bei)。當然他們的(de)(de)(de)價格也相對(dui)便(bian)宜一(yi)些。建設部(bu)(bu)已正式下(xia)文(wen)，淘汰(tai)技術落后的(de)(de)(de)冷鍍(du)(du)(du)鋅(xin)(xin)管(guan)，不(bu)準(zhun)用(yong)冷鍍(du)(du)(du)鋅(xin)(xin)管(guan)作水、煤氣管(guan)。

鍍(du)鋅(xin)板(ban)(ban)選(xuan)擇(ze)(ze)要(yao)注(zhu)(zhu)重(zhong)的幾個要(yao)點，工業企(qi)業的客(ke)戶選(xuan)擇(ze)(ze)專(zhuan)用(yong)工業原(yuan)料(liao)(liao)，要(yao)注(zhu)(zhu)重(zhong)從四個標準(zhun)。一是(shi)(shi)(shi)要(yao)注(zhu)(zhu)重(zhong)品(pin)(pin)牌來進(jin)行選(xuan)擇(ze)(ze)，因為鍍(du)鋅(xin)技術的要(yao)求嚴格(ge)，所(suo)以有(you)(you)的基(ji)(ji)礎(chu)(chu)，當然產品(pin)(pin)質(zhi)量(liang)與技術標準(zhun)都會(hui)更可(ke)靠，都會(hui)有(you)(you)好的專(zhuan)業標準(zhun)。二(er)是(shi)(shi)(shi)要(yao)注(zhu)(zhu)重(zhong)產品(pin)(pin)本身的鍍(du)層質(zhi)量(liang)，鍍(du)層一要(yao)靠技術，二(er)要(yao)靠純(chun)度，所(suo)以從產品(pin)(pin)表面來看(kan)(kan)質(zhi)量(liang)，這是(shi)(shi)(shi)基(ji)(ji)本也是(shi)(shi)(shi)重(zhong)要(yao)的一個標準(zhun)。三是(shi)(shi)(shi)要(yao)看(kan)(kan)基(ji)(ji)礎(chu)(chu)材料(liao)(liao)。鍍(du)鋅(xin)板(ban)(ban)基(ji)(ji)礎(chu)(chu)金屬(shu)材料(liao)(liao)的質(zhi)量(liang)，與成品(pin)(pin)鍍(du)鋅(xin)板(ban)(ban)的質(zhi)量(liang)與耐用(yong)性密切相(xiang)關，所(suo)以在進(jin)行產品(pin)(pin)選(xuan)擇(ze)(ze)的時候(hou)，需要(yao)注(zhu)(zhu)重(zhong)這個細節，而(er)材料(liao)(liao)的提供，就是(shi)(shi)(shi)對于工業生產來說(shuo)，有(you)(you)基(ji)(ji)礎(chu)(chu)條(tiao)件。四是(shi)(shi)(shi)要(yao)注(zhu)(zhu)重(zhong)價格(ge)對比，不是(shi)(shi)(shi)好的就是(shi)(shi)(shi)貴的，但是(shi)(shi)(shi)如果廉價的把產品(pin)(pin)，那是(shi)(shi)(shi)不可(ke)信的。

首先，在鋼結構樓層板中要達到耐火1.5小時，總的來說可以選擇開口板、縮口板、閉口板三大類。遼寧鍍鋅管規范上混凝土要高于開口板肋頂之上80mm，并且板底需配置板底受力筋。還有一種就是再開口板底部刷防火涂料，涂料厚度大于等于15,這樣的話，只要達到構造要求高于肋頂5公分就可以了。鍍鋅管價格而縮口板和閉口板，只需(xu)要(yao)總的樓板厚度大于等于110即(ji)可，但是(shi)縮口板雖(sui)然(ran)在防(fang)火(huo)方面比(bi)開(kai)口板要(yao)好。但是(shi)底(di)部還是(shi)需(xu)要(yao)加板底(di)受力(li)筋，而閉口板則(ze)不需(xu)要(yao)。
