熱鍍鋅鋼格柵板和冷鍍鋅鋼格柵板的區別

1.熱(re)鍍(du)(du)鋅(xin)(xin)(xin)鋼格(ge)(ge)板(ban)又為(wei)熱(re)浸鋅(xin)(xin)(xin)鋼格(ge)(ge)板(ban),是在(zai)高溫(wen)下把鋅(xin)(xin)(xin)錠融化,在(zai)放入(ru)一(yi)些輔助材料,然后把鋼格(ge)(ge)板(ban)浸入(ru)鍍(du)(du)鋅(xin)(xin)(xin)槽中,使鋼格(ge)(ge)板(ban)附著一(yi)層鋅(xin)(xin)(xin)層,熱(re)鍍(du)(du)鋅(xin)(xin)(xin)鋼格(ge)(ge)板(ban)有點(dian)在(zai)于他的防腐能(neng)力強,鍍(du)(du)鋅(xin)(xin)(xin)層的附著力和(he)硬度較好。 冷鍍(du)鋅鋼格板(ban)(ban)即電(dian)鍍(du)鋅鋼格板(ban)(ban),是把鋅鹽溶液通過(guo)電(dian)解,給(gei)鍍(du)件上(shang)鍍(du)層,一般來說不用加熱(re),上(shang)鋅量很(hen)少(shao),遇到潮濕環(huan)境(jing)容易脫落。 

2.針對(dui)鋼格板(ban)而言,廠家強烈建(jian)議用(yong)熱鍍(du)鋅,熱鍍(du)鋅(xin)是化學處(chu)理(li),屬于電化學反(fan)應,冷鍍(du)鋅(xin)是物理(li)處(chu)理(li),只是在(zai)表面刷(shua)一層鋅(xin),所以鋅(xin)層容(rong)易脫落,建筑(zhu)施(shi)工中多采用熱鍍(du)鋅(xin)。 

3.從工藝上區分(fen):首先(xian)熱鍍鋅(xin)是將鋼(gang)格板除油(you),酸洗,浸藥(yao),烘干后浸入熔(rong)化的鋅(xin)液里一定時間,提出來即可(ke)。冷(leng)鍍(du)(du)(du)鋅(xin)(xin)(xin)鋼格板(ban)是(shi)利(li)用電(dian)解設備(bei)(bei)將工(gong)件(jian)經過除油,酸洗(xi)后(hou)放入成分為鋅(xin)(xin)(xin)鹽的(de)溶液中,并連接電(dian)解設備(bei)(bei)的(de)負極;在(zai)工(gong)件(jian)的(de)對面放置鋅(xin)(xin)(xin)板(ban)連接在(zai)點解設備(bei)(bei)的(de)正(zheng)(zheng)極,接通電(dian)源,利(li)用電(dian)流從正(zheng)(zheng)極向負極的(de)定向移動,就會在(zai)工(gong)件(jian)上沉積(ji)一層鋅(xin)(xin)(xin)。熱鍍(du)(du)(du)鋅(xin)(xin)(xin)鋼格板(ban)外表沒有冷(leng)鍍(du)(du)(du)鋅(xin)(xin)(xin)鋼格板(ban)細膩光亮(liang),但(dan)鋅(xin)(xin)(xin)層厚度(du)方面熱鍍(du)(du)(du)鋅(xin)(xin)(xin)要比(bi)冷(leng)鍍(du)(du)(du)鋅(xin)(xin)(xin)高出(chu)幾十倍,防腐(fu)蝕性(xing)能(neng)也是(shi)電(dian)鍍(du)(du)(du)鋅(xin)(xin)(xin)的(de)幾十倍。 

4.從環保問題(ti)上看熱(re)鍍(du)(du)鋅污(wu)染物(wu)(wu)排(pai)放(fang)更少(shao)一些(xie),熱(re)鍍(du)(du)鋅的(de)(de)(de)污(wu)染物(wu)(wu)主要(yao)是(shi)酸(suan)洗工(gong)件的(de)(de)(de)廢(fei)酸(suan),冷鍍(du)(du)鋅的(de)(de)(de)污(wu)染物(wu)(wu)主要(yao)包(bao)括酸(suan)洗工(gong)件的(de)(de)(de)廢(fei)酸(suan),電鍍(du)(du)廢(fei)液(ye)(ye),飛(fei)鈍化(hua)液(ye)(ye)等,冷鍍(du)(du)鋅的(de)(de)(de)污(wu)染物(wu)(wu)排(pai)放(fang)種類和(he)數量都大(da)大(da)超(chao)過熱(re)鍍(du)(du)鋅。
