鋼(gang)格(ge)柵板(ban)(ban)(ban)用(yong)(yong)(yong)幾種方(fang)(fang)法(fa)鍍(du)(du)鋅(xin)(xin)。鍍(du)(du)鋅(xin)(xin)有(you)兩種方(fang)(fang)法(fa)，冷鍍(du)(du)鋅(xin)(xin)和(he)熱鍍(du)(du)鋅(xin)(xin)。鍍(du)(du)鋅(xin)(xin)鋼(gang)格(ge)柵板(ban)(ban)(ban)可(ke)起到防氧化作用(yong)(yong)(yong)，延長(chang)其使(shi)用(yong)(yong)(yong)壽命。熱鍍(du)(du)鋅(xin)(xin)鋼(gang)網架在(zai)(zai) ph6-ph12之間的(de)(de)(de)(de)耐蝕性(xing)，其使(shi)用(yong)(yong)(yong)壽命與外(wai)(wai)(wai)界環境有(you)很大關系，環境干燥(zao)，其使(shi)用(yong)(yong)(yong)壽命可(ke)達70-80年(nian)，行(xing)業一(yi)般在(zai)(zai)20-30年(nian)左(zuo)右(you)。冷鍍(du)(du)鋅(xin)(xin)的(de)(de)(de)(de)使(shi)用(yong)(yong)(yong)年(nian)限相對較短，2、3年(nian)開始(shi)出現銹(xiu)蝕現象。不(bu)鍍(du)(du)鋅(xin)(xin)，不(bu)僅外(wai)(wai)(wai)觀(guan)粗糙難(nan)看(kan)，而且可(ke)以在(zai)(zai)產品表(biao)(biao)(biao)(biao)面(mian)上涂(tu)漆(qi)，不(bu)做加工等集中方(fang)(fang)式。踏板(ban)(ban)(ban)使(shi)用(yong)(yong)(yong)壽命的(de)(de)(de)(de)熱浸鍍(du)(du)鋅(xin)(xin)，最長(chang)可(ke)達40-70年(nian)。冷鍍(du)(du)鋅(xin)(xin)排水溝蓋的(de)(de)(de)(de)長(chang)度(du)是3年(nian)。彩繪鋼(gang)格(ge)柵板(ban)(ban)(ban)，5-7年(nian)。非鍍(du)(du)鋅(xin)(xin)產品表(biao)(biao)(biao)(biao)面(mian)容易發黑、生(sheng)銹(xiu)，而鍍(du)(du)鋅(xin)(xin)表(biao)(biao)(biao)(biao)面(mian)非常光亮，使(shi)用(yong)(yong)(yong)壽命長(chang)，美觀(guan)耐用(yong)(yong)(yong)。生(sheng)產廠家在(zai)(zai)熱浸鍍(du)(du)鋅(xin)(xin)前(qian)要做好(hao)準(zhun)備工作: 鋼(gang)板(ban)(ban)(ban)柵進入熱浸鍍(du)(du)鋅(xin)(xin)池前(qian)應保證(zheng)表(biao)(biao)(biao)(biao)面(mian)清潔(jie)無(wu)污(wu)(wu)垢(gou)，這里強烈推薦酸洗(xi)清潔(jie)表(biao)(biao)(biao)(biao)面(mian)的(de)(de)(de)(de)簡(jian)單方(fang)(fang)法(fa)，但應避免過度(du)酸洗(xi)。不(bu)能(neng)用(yong)(yong)(yong)于(yu)去除(chu)(chu)外(wai)(wai)(wai)觀(guan)上的(de)(de)(de)(de)污(wu)(wu)垢(gou)，如(ru)油(you)污(wu)(wu)、油(you)漆(qi)、爐渣等污(wu)(wu)垢(gou)應在(zai)(zai)酸洗(xi)前(qian)去除(chu)(chu)，如(ru)果不(bu)直接去除(chu)(chu)，會直接影響鋼(gang)板(ban)(ban)(ban)的(de)(de)(de)(de)外(wai)(wai)(wai)觀(guan)，后續工藝是無(wu)意義的(de)(de)(de)(de)。有(you)一(yi)點，在(zai)(zai)鋼(gang)格(ge)板(ban)(ban)(ban)的(de)(de)(de)(de)加工過程中，外(wai)(wai)(wai)觀(guan)應該(gai)不(bu)要有(you)太大的(de)(de)(de)(de)氣孔(kong)和(he)縮孔(kong)，如(ru)果氣孔(kong)或(huo)焊接面(mian)過于(yu)突出應該(gai)選擇(ze)噴砂、拋(pao)丸、電解酸洗(xi)等方(fang)(fang)法(fa)來處理，這也是產品質(zhi)量好(hao)壞的(de)(de)(de)(de)決(jue)定性(xing)因素！
