鍍(du)鋅(xin)(xin)(xin)卷分熱鍍(du)鋅(xin)(xin)(xin)和電鍍(du)鋅(xin)(xin)(xin)兩種(zhong)，熱鍍(du)鋅(xin)(xin)(xin)鍍(du)鋅(xin)(xin)(xin)層(ceng)厚，具有(you)鍍(du)層(ceng)均勻(yun)，附著力強，使用壽命長等優點。電鍍(du)鋅(xin)(xin)(xin)成本低(di)，表(biao)面不(bu)是很光滑，其(qi)本身的(de)耐(nai)腐蝕(shi)性(xing)(xing)比熱鍍(du)鋅(xin)(xin)(xin)管(guan)相差很多。提起鍍(du)鋅(xin)(xin)(xin)管(guan)，可能沒接(jie)觸(chu)過(guo)建(jian)材的(de)朋友并不(bu)了(le)解。從1935年建(jian)立一條連續涂(tu)層(ceng)鋼板(ban)線開始，彩涂(tu)板(ban)得到了(le)廣泛應用，目前彩涂(tu)板(ban)的(de)品種(zhong)繁(fan)多，大約超過(guo)600種(zhong)，彩涂(tu)板(ban)兼(jian)有(you)機(ji)聚合物與(yu)鋼板(ban)兩者(zhe)的(de)優點，既有(you)有(you)機(ji)聚合物的(de)良好著色性(xing)(xing)、成型性(xing)(xing)、耐(nai)蝕(shi)性(xing)(xing)、裝飾性(xing)(xing)、又有(you)鋼板(ban)的(de)高(gao)強度和易加(jia)工性(xing)(xing)，能很容易地進(jin)行沖(chong)壓(ya)裁(cai)剪、彎曲、深沖(chong)等加(jia)工。

鍍鋅板價格鍍鋅鋼板按用途又可分為一般用、屋頂用、建筑外側板用、結構用、瓦壟板用、拉伸用和深沖用等鍍鋅鋼板。西安鍍鋅板對于一(yi)般(ban)防保護用(yong)(yong)鍍(du)(du)層，可以采用(yong)(yong)堿性鋅(xin)(xin)酸(suan)鹽鍍(du)(du)鋅(xin)(xin)彩色鈍(dun)(dun)化(hua)(hua)工(gong)藝。有(you)時(shi)為(wei)了產品的(de)(de)(de)(de)配色需要，也可以采用(yong)(yong)藍白色鈍(dun)(dun)化(hua)(hua)工(gong)藝，比如軍(jun)綠色鈍(dun)(dun)化(hua)(hua)、黑色鈍(dun)(dun)化(hua)(hua)等。為(wei)提高鋼(gang)管的(de)(de)(de)(de)耐腐(fu)蝕(shi)性能，對一(yi)般(ban)鋼(gang)管進行鍍(du)(du)鋅(xin)(xin)。鍍(du)(du)鋅(xin)(xin)卷(juan)分(fen)熱(re)鍍(du)(du)鋅(xin)(xin)和電(dian)鍍(du)(du)鋅(xin)(xin)兩種(zhong)，熱(re)鍍(du)(du)鋅(xin)(xin)鍍(du)(du)鋅(xin)(xin)層厚，電(dian)鍍(du)(du)鋅(xin)(xin)成(cheng)(cheng)本(ben)低(di)，表面(mian)不是很光滑(hua)。吹氧(yang)焊管：用(yong)(yong)作煉鋼(gang)吹氧(yang)用(yong)(yong)管，一(yi)般(ban)用(yong)(yong)小口(kou)徑的(de)(de)(de)(de)焊接鋼(gang)管，規格(ge)由(you)3/8-2寸八(ba)種(zhong)。用(yong)(yong)08、10、15、20或者195-Q235的(de)(de)(de)(de)鋼(gang)帶制作成(cheng)(cheng)的(de)(de)(de)(de)，為(wei)了防腐(fu)蝕(shi)，有(you)得進行滲鋁處理(li)。鍍(du)(du)鋅(xin)(xin)其防護作用(yong)(yong)更(geng)強(qiang)，抗(kang)腐(fu)蝕(shi)能力強(qiang)。整個結(jie)構(gou)由(you)鋅(xin)(xin)，形成(cheng)(cheng)致(zhi)密的(de)(de)(de)(de)四元(yuan)結(jie)晶體，此結(jie)晶體在(zai)鋼(gang)板(ban)上形成(cheng)(cheng)一(yi)層屏障(zhang)， 因(yin)而有(you)效的(de)(de)(de)(de)防止腐(fu)蝕(shi)因(yin)子穿透。 耐腐(fu)蝕(shi)性來自鋅(xin)(xin)的(de)(de)(de)(de)障(zhang)礙(ai)層保護功能強(qiang)。

首先，在鋼結構樓層板(ban)(ban)(ban)(ban)(ban)(ban)中要(yao)(yao)(yao)達到(dao)耐(nai)火1.5小(xiao)時，總的(de)來說(shuo)可以選擇開(kai)口(kou)板(ban)(ban)(ban)(ban)(ban)(ban)、縮口(kou)板(ban)(ban)(ban)(ban)(ban)(ban)、閉(bi)(bi)口(kou)板(ban)(ban)(ban)(ban)(ban)(ban)三大類。規范(fan)上(shang)混凝(ning)土(tu)要(yao)(yao)(yao)高于(yu)(yu)開(kai)口(kou)板(ban)(ban)(ban)(ban)(ban)(ban)肋頂之上(shang)80mm，并且板(ban)(ban)(ban)(ban)(ban)(ban)底需(xu)(xu)配置板(ban)(ban)(ban)(ban)(ban)(ban)底受(shou)力筋(jin)。還有(you)一種就(jiu)是(shi)再開(kai)口(kou)板(ban)(ban)(ban)(ban)(ban)(ban)底部刷(shua)防火涂料(liao)，涂料(liao)厚度(du)大于(yu)(yu)等于(yu)(yu)15,這樣的(de)話，只(zhi)要(yao)(yao)(yao)達到(dao)構造要(yao)(yao)(yao)求高于(yu)(yu)肋頂5公分就(jiu)可以了。而縮口(kou)板(ban)(ban)(ban)(ban)(ban)(ban)和閉(bi)(bi)口(kou)板(ban)(ban)(ban)(ban)(ban)(ban)，只(zhi)需(xu)(xu)要(yao)(yao)(yao)總的(de)樓板(ban)(ban)(ban)(ban)(ban)(ban)厚度(du)大于(yu)(yu)等于(yu)(yu)110即可，但(dan)是(shi)縮口(kou)板(ban)(ban)(ban)(ban)(ban)(ban)雖然(ran)在防火方面(mian)比(bi)開(kai)口(kou)板(ban)(ban)(ban)(ban)(ban)(ban)要(yao)(yao)(yao)好。但(dan)是(shi)底部還是(shi)需(xu)(xu)要(yao)(yao)(yao)加板(ban)(ban)(ban)(ban)(ban)(ban)底受(shou)力筋(jin)，而閉(bi)(bi)口(kou)板(ban)(ban)(ban)(ban)(ban)(ban)則(ze)不需(xu)(xu)要(yao)(yao)(yao)。
