大(da)家都知道鍍(du)鋅(xin)水(shui)箱主要(yao)采用優質的Q235鋼板(ban)(ban)沖壓而成，形成1000×1000、1000×500、500×500等標準板(ban)(ban)塊后經熱浸(jin)鍍(du)鋅(xin)處理(li)后形成鍍(du)鋅(xin)水(shui)箱板(ban)(ban)。今天(tian)我們(men)來了(le)解(jie)下鍍(du)鋅(xin)水(shui)箱鍍(du)鋅(xin)層厚度與質量的關系。

鋼(gang)(gang)(gang)鐵(tie)材料的(de)(de)(de)(de)十分(fen)之一消耗(hao)于腐蝕,為此,人(ren)們通過各種(zhong)手段來避免或減少(shao)鋼(gang)(gang)(gang)鐵(tie)由(you)于腐蝕而(er)(er)造成的(de)(de)(de)(de)損(sun)失。鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)(xin)既可以(yi)防止(zhi)鋼(gang)(gang)(gang)鐵(tie)的(de)(de)(de)(de)大氣腐蝕,又能(neng)使自身腐蝕速(su)度(du)(du)減緩。鋼(gang)(gang)(gang)板(ban)、鋼(gang)(gang)(gang)絲(si)、型鋼(gang)(gang)(gang)、器皿、緊固件等都用(yong)鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)(xin)來進行防腐,鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)(xin)水箱的(de)(de)(de)(de)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)(xin)消耗(hao)量(liang)(liang)占鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)(xin)產(chan)量(liang)(liang)的(de)(de)(de)(de)50%左(zuo)右(you)。鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)(xin)層(ceng)(ceng)(ceng)(ceng)既可以(yi)用(yong)電鍍(du)(du)(du),也可以(yi)用(yong)熱(re)鍍(du)(du)(du)進行鍍(du)(du)(du)覆。電鍍(du)(du)(du)能(neng)獲得(de)純鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)(xin)層(ceng)(ceng)(ceng)(ceng),鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)(xin)層(ceng)(ceng)(ceng)(ceng)與(yu)(yu)鋼(gang)(gang)(gang)基體的(de)(de)(de)(de)結合靠(kao)原子間的(de)(de)(de)(de)引力;熱(re)鍍(du)(du)(du)所獲得(de)的(de)(de)(de)(de)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)(xin)層(ceng)(ceng)(ceng)(ceng)則是不純的(de)(de)(de)(de),鋼(gang)(gang)(gang)基體與(yu)(yu)純鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)(xin)層(ceng)(ceng)(ceng)(ceng)之間存在著鐵(tie)-鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)(xin)合金層(ceng)(ceng)(ceng)(ceng),鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)(xin)層(ceng)(ceng)(ceng)(ceng)與(yu)(yu)鋼(gang)(gang)(gang)基的(de)(de)(de)(de)結合是由(you)于高溫下鐵(tie)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)(xin)原子的(de)(de)(de)(de)相互擴散(san)和液(ye)態鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)(xin)對鋼(gang)(gang)(gang)絲(si)表面潤濕作用(yong)的(de)(de)(de)(de)結果。鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)(xin)層(ceng)(ceng)(ceng)(ceng)質(zhi)量(liang)(liang)、厚(hou)(hou)度(du)(du)的(de)(de)(de)(de)測(ce)定(ding)及(ji)控制不僅決(jue)定(ding)生(sheng)產(chan)成本,同(tong)時決(jue)定(ding)產(chan)品(pin)的(de)(de)(de)(de)使用(yong)壽命(ming),從而(er)(er)要求快速(su)、準(zhun)確地測(ce)定(ding)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)(xin)層(ceng)(ceng)(ceng)(ceng)質(zhi)量(liang)(liang)及(ji)厚(hou)(hou)度(du)(du)。1鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)(xin)產(chan)品(pin)中(zhong)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)(xin)層(ceng)(ceng)(ceng)(ceng)質(zhi)量(liang)(liang)、厚(hou)(hou)度(du)(du)的(de)(de)(de)(de)測(ce)定(ding)鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)(xin)產(chan)品(pin)有板(ban)、帶、絲(si)、棒(bang)、管等各種(zhong)形狀,應采用(yong)不同(tong)的(de)(de)(de)(de)標準(zhun)、方法(fa)(fa)計算出樣品(pin)的(de)(de)(de)(de)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)(xin)層(ceng)(ceng)(ceng)(ceng)面質(zhi)量(liang)(liang)。1.1鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)絲(si)及(ji)鋼(gang)(gang)(gang)棒(bang)1.1.1鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)(xin)層(ceng)(ceng)(ceng)(ceng)的(de)(de)(de)(de)性(xing)(xing)能(neng)及(ji)質(zhi)量(liang)(liang)檢驗標準(zhun)(1)鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)(xin)量(liang)(liang)。鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)(xin)量(liang)(liang)反映鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)(xin)層(ceng)(ceng)(ceng)(ceng)的(de)(de)(de)(de)厚(hou)(hou)度(du)(du)和鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)(xin)層(ceng)(ceng)(ceng)(ceng)的(de)(de)(de)(de)耐久性(xing)(xing),其檢驗方法(fa)(fa)參照GB/T 2973—2004《鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)絲(si)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)(xin)層(ceng)(ceng)(ceng)(ceng)質(zhi)量(liang)(liang)試驗方法(fa)(fa)》。(2)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)(xin)層(ceng)(ceng)(ceng)(ceng)均勻性(xing)(xing)。鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)(xin)層(ceng)(ceng)(ceng)(ceng)分(fen)布均勻性(xing)(xing)關系(xi)到鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)(xin)層(ceng)(ceng)(ceng)(ceng)的(de)(de)(de)(de)使用(yong)壽命(ming)。
