鋼(gang)(gang)(gang)格柵板(ban)用(yong)(yong)幾種方(fang)法(fa)鍍(du)(du)(du)(du)鋅(xin)(xin)。鍍(du)(du)(du)(du)鋅(xin)(xin)有(you)兩種方(fang)法(fa)，冷(leng)鍍(du)(du)(du)(du)鋅(xin)(xin)和熱鍍(du)(du)(du)(du)鋅(xin)(xin)。鍍(du)(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)格柵板(ban)可起(qi)到防氧化作用(yong)(yong)，延長(chang)其使(shi)(shi)(shi)用(yong)(yong)壽命(ming)(ming)。熱鍍(du)(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)網架在(zai) ph6-ph12之間的(de)(de)(de)耐蝕性，其使(shi)(shi)(shi)用(yong)(yong)壽命(ming)(ming)與(yu)外(wai)界(jie)環(huan)(huan)境有(you)很大關系，環(huan)(huan)境干燥，其使(shi)(shi)(shi)用(yong)(yong)壽命(ming)(ming)可達(da)70-80年(nian)(nian)(nian)，行業一般在(zai)20-30年(nian)(nian)(nian)左右(you)。冷(leng)鍍(du)(du)(du)(du)鋅(xin)(xin)的(de)(de)(de)使(shi)(shi)(shi)用(yong)(yong)年(nian)(nian)(nian)限相對(dui)較短，2、3年(nian)(nian)(nian)開(kai)始出現(xian)(xian)銹蝕現(xian)(xian)象(xiang)。不(bu)鍍(du)(du)(du)(du)鋅(xin)(xin)，不(bu)僅外(wai)觀(guan)(guan)粗(cu)糙難(nan)看，而且(qie)可以在(zai)產品表(biao)面上(shang)涂漆，不(bu)做加(jia)工(gong)等集中(zhong)方(fang)式。踏板(ban)使(shi)(shi)(shi)用(yong)(yong)壽命(ming)(ming)的(de)(de)(de)熱浸鍍(du)(du)(du)(du)鋅(xin)(xin)，最長(chang)可達(da)40-70年(nian)(nian)(nian)。冷(leng)鍍(du)(du)(du)(du)鋅(xin)(xin)排水溝蓋的(de)(de)(de)長(chang)度是3年(nian)(nian)(nian)。彩繪鋼(gang)(gang)(gang)格柵板(ban)，5-7年(nian)(nian)(nian)。非(fei)鍍(du)(du)(du)(du)鋅(xin)(xin)產品表(biao)面容易發黑、生銹，而鍍(du)(du)(du)(du)鋅(xin)(xin)表(biao)面非(fei)常(chang)光亮(liang)，使(shi)(shi)(shi)用(yong)(yong)壽命(ming)(ming)長(chang)，美觀(guan)(guan)耐用(yong)(yong)。生產廠家在(zai)熱浸鍍(du)(du)(du)(du)鋅(xin)(xin)前(qian)要做好準備工(gong)作: 鋼(gang)(gang)(gang)板(ban)柵進入熱浸鍍(du)(du)(du)(du)鋅(xin)(xin)池(chi)前(qian)應(ying)保證(zheng)表(biao)面清(qing)潔無污(wu)垢(gou)，這里強烈推薦酸洗(xi)清(qing)潔表(biao)面的(de)(de)(de)簡單方(fang)法(fa)，但應(ying)避免(mian)過(guo)度酸洗(xi)。不(bu)能用(yong)(yong)于(yu)去除外(wai)觀(guan)(guan)上(shang)的(de)(de)(de)污(wu)垢(gou)，如(ru)油污(wu)、油漆、爐渣等污(wu)垢(gou)應(ying)在(zai)酸洗(xi)前(qian)去除，如(ru)果(guo)不(bu)直接(jie)去除，會直接(jie)影響鋼(gang)(gang)(gang)板(ban)的(de)(de)(de)外(wai)觀(guan)(guan)，后續工(gong)藝(yi)是無意義的(de)(de)(de)。有(you)一點(dian)，在(zai)鋼(gang)(gang)(gang)格板(ban)的(de)(de)(de)加(jia)工(gong)過(guo)程(cheng)中(zhong)，外(wai)觀(guan)(guan)應(ying)該不(bu)要有(you)太大的(de)(de)(de)氣(qi)孔和縮孔，如(ru)果(guo)氣(qi)孔或(huo)焊接(jie)面過(guo)于(yu)突出應(ying)該選(xuan)擇(ze)噴砂、拋丸、電解酸洗(xi)等方(fang)法(fa)來(lai)處理，這也是產品質(zhi)量好壞的(de)(de)(de)決定性因素！
