鍍鋅圓好的白鐵風管法蘭工藝流程:成品酸洗-水洗-加助鍍液-烘干-掛鍍-冷卻-藥化-清洗-打磨-熱鍍鋅完工 鍍鋅圓法蘭工白鐵風管安裝藝(yi)原理:將鐵件清洗干凈,然后(hou)溶劑處理,烘干后(hou)浸入鋅(xin)液中,鐵與熔融鋅(xin)反應生成一合金化的(de)鋅(xin)層,其流(liu)程為:脫脂--水洗--酸洗--助鍍--烘干--熱浸鍍鋅(xin)--分離--冷(leng)卻(que)鈍化。
熱鍍鋅的合金層好的白鐵風管的厚度主要取決了鋼材的硅含量等化學成份,鋼材的橫截面積大小,鋼材表面的白鐵風管安裝粗糙程(cheng)度(du),鋅(xin)(xin)(xin)(xin)鍋溫(wen)度(du),浸鋅(xin)(xin)(xin)(xin)時(shi)間,冷(leng)卻(que)快慢(man),冷(leng)軋變形(xing)等(deng)。 鍍(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)圓法(fa)蘭優點: 1、 處理費(fei)用低:熱(re)浸鍍(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)防(fang)銹(xiu)的(de)(de)(de)費(fei)用要(yao)比其他(ta)漆料涂層(ceng)(ceng)的(de)(de)(de)費(fei)用低; 2、 持久耐(nai)用:在(zai)(zai)郊區環(huan)境(jing)下,標準(zhun)的(de)(de)(de)熱(re)鍍(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)防(fang)銹(xiu)的(de)(de)(de)厚度(du),可(ke)(ke)(ke)保(bao)持50年以上而(er)不必修(xiu)補(bu);在(zai)(zai)市區或近(jin)海區域,標準(zhun)的(de)(de)(de)熱(re)鍍(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)防(fang)銹(xiu)層(ceng)(ceng)則(ze)可(ke)(ke)(ke)保(bao)持20年而(er)不必修(xiu)補(bu); 3、 可(ke)(ke)(ke)靠性(xing)好:鍍(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)層(ceng)(ceng)與鋼材(cai)間是(shi)冶(ye)金結合,成為鋼表(biao)面的(de)(de)(de)一部(bu)(bu)份(fen),因此鍍(du)(du)(du)(du)(du)(du)層(ceng)(ceng)的(de)(de)(de)持久性(xing)較(jiao)為可(ke)(ke)(ke)靠; 4、 鍍(du)(du)(du)(du)(du)(du)層(ceng)(ceng)的(de)(de)(de)韌性(xing)強:鍍(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)層(ceng)(ceng)形(xing)成一種特別的(de)(de)(de)冶(ye)金結構(gou),這(zhe)種結構(gou)能(neng)承受在(zai)(zai)運送(song)及使用時(shi)受到機械損傷; 5、 全(quan)面性(xing)保(bao)護:鍍(du)(du)(du)(du)(du)(du)件的(de)(de)(de)每一部(bu)(bu)分都能(neng)鍍(du)(du)(du)(du)(du)(du)上鋅(xin)(xin)(xin)(xin),即使在(zai)(zai)凹陷(xian)處、尖角及隱(yin)藏處都能(neng)全(quan)面地(di)受到保(bao)護; 6、 省(sheng)時(shi)省(sheng)力:鍍(du)(du)(du)(du)(du)(du)鋅(xin)(xin)(xin)(xin)過程(cheng)要(yao)比其他(ta)涂層(ceng)(ceng)的(de)(de)(de)施工法(fa)更快捷,并且可(ke)(ke)(ke)避免安裝后在(zai)(zai)工地(di)上涂刷所(suo)需(xu)的(de)(de)(de)時(shi)間。
