一、鍍鋅板材質介紹
鍍(du)(du)(du)(du)鋅(xin)板是一種(zhong)通過鍍(du)(du)(du)(du)鋅(xin)工藝在鋼板表面鍍(du)(du)(du)(du)上(shang)一層鋅(xin)的(de)(de)而制(zhi)成的(de)(de)合金產品,是一種(zhong)用途十分廣泛的(de)(de)建(jian)筑材料。鍍(du)(du)(du)(du)鋅(xin)板按生產以及加工的(de)(de)方法的(de)(de)不同可分為熱浸(jin)鍍(du)(du)(du)(du)鋅(xin)、合金化(hua)鍍(du)(du)(du)(du)鋅(xin)、電鍍(du)(du)(du)(du)鋅(xin)、單(dan)雙面鍍(du)(du)(du)(du)鋅(xin)和合金、復合鍍(du)(du)(du)(du)鋅(xin)五(wu)種(zhong)類(lei)型。
二、鍍鋅板會生銹嗎
鍍鋅板也會生銹,只是鍍鋅層首先被氧化保護了鋼管不生銹,其使用壽命更長,此外,保管不當,刮刮碰碰,水侵汽熏都可能導致生銹。劣質鍍鋅板可能因為鋅包裹的不均勻,露出里面的金屬,產生腐蝕,建議選購優質鍍鋅板品牌的(de)產品,防銹性能更(geng)好(hao),使用壽命更(geng)長。
三、鍍鋅管焊接技巧
鍍(du)鋅管焊接(jie)焊縫(feng)處必須(xu)打(da)磨,將(jiang)鍍(du)鋅層打(da)磨掉;焊接(jie)手法方(fang)面,將(jiang)焊條端部向(xiang)前(qian)(qian)移(yi)出約5~7mm左右,當(dang)使鋅層熔(rong)化后(hou)再回到原(yuan)來位置繼續向(xiang)前(qian)(qian)施焊。在橫焊和立(li)焊時采用(yong)前(qian)(qian)后(hou)往返運條技術,可(ke)以提高焊接(jie)質(zhi)量。
四、鍍鋅板和不銹鋼的區別
外觀方面(mian),鍍(du)(du)鋅(xin)板(ban)和不(bu)銹鋼(gang)很(hen)好區分,鍍(du)(du)鋅(xin)板(ban)上面(mian)有鋅(xin)花,不(bu)銹鋼(gang)要么是黑皮(pi)要么是白皮(pi),白皮(pi)的不(bu)銹鋼(gang)很(hen)亮,有拉絲的效果。用途方面(mian),鍍(du)(du)鋅(xin)板(ban)是防銹的,不(bu)銹鋼(gang)耐空氣、蒸汽、水(shui)等弱腐蝕介質。
五、鍍鋅板和冷軋板的區別
首(shou)先,外觀不(bu)(bu)同,鍍(du)鋅(xin)(xin)板(ban)(ban)(ban)是白色的(de)(de)(de),冷(leng)(leng)壓(ya)板(ban)(ban)(ban)是黑色的(de)(de)(de);其次基材不(bu)(bu)同,普通(tong)冷(leng)(leng)軋板(ban)(ban)(ban)材是由熱(re)(re)軋薄(bo)板(ban)(ban)(ban)通(tong)過冷(leng)(leng)壓(ya)力加工(gong)(gong)而得到的(de)(de)(de)產品,鍍(du)鋅(xin)(xin)板(ban)(ban)(ban)是指表面(mian)鍍(du)有一層(ceng)鋅(xin)(xin)的(de)(de)(de)鋼板(ban)(ban)(ban)。兩者物理特性也不(bu)(bu)同,熱(re)(re)鍍(du)鋅(xin)(xin)鋼板(ban)(ban)(ban)比冷(leng)(leng)軋板(ban)(ban)(ban)抗腐(fu)蝕(shi)。 熱(re)(re)鍍(du)鋅(xin)(xin)鋼板(ban)(ban)(ban)的(de)(de)(de)特點耐腐(fu)蝕(shi)強、表面(mian)質量好、利(li)于深加工(gong)(gong)、經濟實用。熱(re)(re)鍍(du)鋅(xin)(xin)鋼板(ban)(ban)(ban)的(de)(de)(de)拉延性能(neng)不(bu)(bu)如冷(leng)(leng)軋板(ban)(ban)(ban)可靠。 熱(re)(re)鍍(du)鋅(xin)(xin)鋼板(ban)(ban)(ban)不(bu)(bu)如冷(leng)(leng)軋鋼板(ban)(ban)(ban)容(rong)易焊(han),在焊(han)接時(shi)鋅(xin)(xin)層(ceng)受破壞。
