鋼(gang)(gang)(gang)格(ge)柵(zha)(zha)板用(yong)(yong)(yong)(yong)(yong)幾(ji)種方法(fa)鍍(du)(du)(du)鋅(xin)(xin)(xin)。鍍(du)(du)(du)鋅(xin)(xin)(xin)有(you)兩種方法(fa)，冷(leng)鍍(du)(du)(du)鋅(xin)(xin)(xin)和熱鍍(du)(du)(du)鋅(xin)(xin)(xin)。鍍(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)(gang)(gang)格(ge)柵(zha)(zha)板可(ke)起到防(fang)氧(yang)化作用(yong)(yong)(yong)(yong)(yong)，延長(chang)(chang)其使(shi)用(yong)(yong)(yong)(yong)(yong)壽(shou)命(ming)。熱鍍(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)(gang)(gang)網架(jia)在 ph6-ph12之間的(de)(de)(de)(de)耐蝕性，其使(shi)用(yong)(yong)(yong)(yong)(yong)壽(shou)命(ming)與外(wai)(wai)界環(huan)境有(you)很大關系，環(huan)境干(gan)燥，其使(shi)用(yong)(yong)(yong)(yong)(yong)壽(shou)命(ming)可(ke)達(da)70-80年(nian)(nian)，行業一(yi)般在20-30年(nian)(nian)左右(you)。冷(leng)鍍(du)(du)(du)鋅(xin)(xin)(xin)的(de)(de)(de)(de)使(shi)用(yong)(yong)(yong)(yong)(yong)年(nian)(nian)限相(xiang)對較短，2、3年(nian)(nian)開始(shi)出現銹蝕現象(xiang)。不(bu)鍍(du)(du)(du)鋅(xin)(xin)(xin)，不(bu)僅外(wai)(wai)觀(guan)(guan)粗糙(cao)難(nan)看，而且(qie)可(ke)以在產品表面(mian)上涂漆，不(bu)做加(jia)工(gong)等(deng)集(ji)中(zhong)方式。踏(ta)板使(shi)用(yong)(yong)(yong)(yong)(yong)壽(shou)命(ming)的(de)(de)(de)(de)熱浸鍍(du)(du)(du)鋅(xin)(xin)(xin)，最長(chang)(chang)可(ke)達(da)40-70年(nian)(nian)。冷(leng)鍍(du)(du)(du)鋅(xin)(xin)(xin)排水溝蓋的(de)(de)(de)(de)長(chang)(chang)度(du)是(shi)(shi)3年(nian)(nian)。彩繪鋼(gang)(gang)(gang)格(ge)柵(zha)(zha)板，5-7年(nian)(nian)。非(fei)(fei)鍍(du)(du)(du)鋅(xin)(xin)(xin)產品表面(mian)容易(yi)發黑、生(sheng)銹，而鍍(du)(du)(du)鋅(xin)(xin)(xin)表面(mian)非(fei)(fei)常光亮，使(shi)用(yong)(yong)(yong)(yong)(yong)壽(shou)命(ming)長(chang)(chang)，美觀(guan)(guan)耐用(yong)(yong)(yong)(yong)(yong)。生(sheng)產廠家在熱浸鍍(du)(du)(du)鋅(xin)(xin)(xin)前要做好(hao)準備工(gong)作: 鋼(gang)(gang)(gang)板柵(zha)(zha)進(jin)入熱浸鍍(du)(du)(du)鋅(xin)(xin)(xin)池前應(ying)保證(zheng)表面(mian)清潔無污(wu)(wu)垢(gou)，這里強烈推薦酸(suan)洗(xi)(xi)清潔表面(mian)的(de)(de)(de)(de)簡單方法(fa)，但應(ying)避(bi)免過(guo)度(du)酸(suan)洗(xi)(xi)。不(bu)能用(yong)(yong)(yong)(yong)(yong)于去除外(wai)(wai)觀(guan)(guan)上的(de)(de)(de)(de)污(wu)(wu)垢(gou)，如油污(wu)(wu)、油漆、爐(lu)渣等(deng)污(wu)(wu)垢(gou)應(ying)在酸(suan)洗(xi)(xi)前去除，如果(guo)不(bu)直接去除，會直接影(ying)響鋼(gang)(gang)(gang)板的(de)(de)(de)(de)外(wai)(wai)觀(guan)(guan)，后續(xu)工(gong)藝是(shi)(shi)無意義的(de)(de)(de)(de)。有(you)一(yi)點(dian)，在鋼(gang)(gang)(gang)格(ge)板的(de)(de)(de)(de)加(jia)工(gong)過(guo)程中(zhong)，外(wai)(wai)觀(guan)(guan)應(ying)該不(bu)要有(you)太大的(de)(de)(de)(de)氣孔和縮孔，如果(guo)氣孔或(huo)焊(han)接面(mian)過(guo)于突出應(ying)該選擇噴(pen)砂、拋(pao)丸、電解酸(suan)洗(xi)(xi)等(deng)方法(fa)來處(chu)理，這也(ye)是(shi)(shi)產品質量(liang)好(hao)壞的(de)(de)(de)(de)決定性因素！
