鋼(gang)格(ge)柵板(ban)(ban)用(yong)(yong)幾種(zhong)方(fang)法鍍(du)鋅(xin)(xin)(xin)。鍍(du)鋅(xin)(xin)(xin)有兩種(zhong)方(fang)法，冷(leng)鍍(du)鋅(xin)(xin)(xin)和熱(re)鍍(du)鋅(xin)(xin)(xin)。鍍(du)鋅(xin)(xin)(xin)鋼(gang)格(ge)柵板(ban)(ban)可(ke)起到防氧化(hua)作(zuo)用(yong)(yong)，延長其使(shi)(shi)用(yong)(yong)壽命(ming)。熱(re)鍍(du)鋅(xin)(xin)(xin)鋼(gang)網架在(zai) ph6-ph12之間的(de)(de)(de)耐(nai)蝕性，其使(shi)(shi)用(yong)(yong)壽命(ming)與外(wai)界環境有很大(da)關系(xi)，環境干燥(zao)，其使(shi)(shi)用(yong)(yong)壽命(ming)可(ke)達(da)(da)70-80年(nian)(nian)，行(xing)業一般(ban)在(zai)20-30年(nian)(nian)左右。冷(leng)鍍(du)鋅(xin)(xin)(xin)的(de)(de)(de)使(shi)(shi)用(yong)(yong)年(nian)(nian)限(xian)相對較短(duan)，2、3年(nian)(nian)開始出(chu)(chu)現銹蝕現象。不(bu)(bu)鍍(du)鋅(xin)(xin)(xin)，不(bu)(bu)僅外(wai)觀粗(cu)糙難(nan)看，而(er)且可(ke)以在(zai)產品表(biao)(biao)(biao)面(mian)(mian)上涂漆，不(bu)(bu)做(zuo)加工(gong)(gong)等(deng)集中方(fang)式(shi)。踏板(ban)(ban)使(shi)(shi)用(yong)(yong)壽命(ming)的(de)(de)(de)熱(re)浸(jin)鍍(du)鋅(xin)(xin)(xin)，最長可(ke)達(da)(da)40-70年(nian)(nian)。冷(leng)鍍(du)鋅(xin)(xin)(xin)排(pai)水溝蓋(gai)的(de)(de)(de)長度是(shi)3年(nian)(nian)。彩(cai)繪鋼(gang)格(ge)柵板(ban)(ban)，5-7年(nian)(nian)。非鍍(du)鋅(xin)(xin)(xin)產品表(biao)(biao)(biao)面(mian)(mian)容(rong)易發黑、生銹，而(er)鍍(du)鋅(xin)(xin)(xin)表(biao)(biao)(biao)面(mian)(mian)非常光(guang)亮(liang)，使(shi)(shi)用(yong)(yong)壽命(ming)長，美觀耐(nai)用(yong)(yong)。生產廠家在(zai)熱(re)浸(jin)鍍(du)鋅(xin)(xin)(xin)前要做(zuo)好準備(bei)工(gong)(gong)作(zuo): 鋼(gang)板(ban)(ban)柵進入熱(re)浸(jin)鍍(du)鋅(xin)(xin)(xin)池前應(ying)(ying)保證表(biao)(biao)(biao)面(mian)(mian)清(qing)潔無污(wu)垢，這里強烈推薦酸洗(xi)清(qing)潔表(biao)(biao)(biao)面(mian)(mian)的(de)(de)(de)簡(jian)單方(fang)法，但應(ying)(ying)避免過度酸洗(xi)。不(bu)(bu)能(neng)用(yong)(yong)于去(qu)除(chu)外(wai)觀上的(de)(de)(de)污(wu)垢，如油(you)污(wu)、油(you)漆、爐(lu)渣等(deng)污(wu)垢應(ying)(ying)在(zai)酸洗(xi)前去(qu)除(chu)，如果(guo)不(bu)(bu)直接(jie)去(qu)除(chu)，會直接(jie)影響鋼(gang)板(ban)(ban)的(de)(de)(de)外(wai)觀，后續工(gong)(gong)藝是(shi)無意義的(de)(de)(de)。有一點(dian)，在(zai)鋼(gang)格(ge)板(ban)(ban)的(de)(de)(de)加工(gong)(gong)過程中，外(wai)觀應(ying)(ying)該不(bu)(bu)要有太大(da)的(de)(de)(de)氣(qi)(qi)孔(kong)和縮孔(kong)，如果(guo)氣(qi)(qi)孔(kong)或焊接(jie)面(mian)(mian)過于突出(chu)(chu)應(ying)(ying)該選擇噴砂、拋丸、電(dian)解酸洗(xi)等(deng)方(fang)法來處理，這也是(shi)產品質量好壞的(de)(de)(de)決(jue)定性因素！
