重要的鋅專業白鐵加工的化合物是氧化鋅,俗名叫“鋅白”,是著名的白色顏料,用來制造白色油漆等。在室溫下氧化白鐵加工定制鋅是白色(se)的(de),受(shou)熱(re)后(hou)卻會變成黃色(se),而(er)再(zai)冷卻時,又(you)重新變成白色(se)。現在,人(ren)們利(li)用它(ta)的(de)這個(ge)特點,制成“變色(se)溫度(du)計(ji)”——用它(ta)顏色(se)的(de)變化(hua)來測量溫度(du)。
白鐵是專業白鐵加工做風管加工、煙囪加工的好材料,那么在使用白鐵加工的時候需要涉及到哪些工具呢? 專用的白鐵加工白鐵加工剪(jian)刀、方錘(chui)、銼(cuo)、鉗、鑷子(zi)、角尺,鋼尺,白(bai)(bai)鐵剪(jian)、切管(guan)器,電動的卷圓(yuan)機、白(bai)(bai)鐵壓線機、白(bai)(bai)鐵打扣機,如要焊風管(guan)架子(zi),還要用(yong)到電焊機,角等。 白(bai)(bai)鐵加工(gong)(gong)的工(gong)(gong)具是比較簡單的,一般手工(gong)(gong)就能進行(xing)白(bai)(bai)鐵加工(gong)(gong)。
熱鍍鋅的合金層專業白鐵加工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,鋼材表面的白鐵加工定制粗糙(cao)程度(du),鋅(xin)(xin)鍋溫度(du),浸(jin)鋅(xin)(xin)時(shi)(shi)間,冷卻快慢,冷軋變形等。 鍍(du)(du)(du)鋅(xin)(xin)圓法蘭(lan)優點: 1、 處(chu)理費用(yong)低(di):熱浸(jin)鍍(du)(du)(du)鋅(xin)(xin)防銹的(de)費用(yong)要比(bi)其他漆料(liao)涂層(ceng)(ceng)的(de)費用(yong)低(di); 2、 持(chi)(chi)久(jiu)耐用(yong):在(zai)(zai)郊區(qu)環境下,標準(zhun)的(de)熱鍍(du)(du)(du)鋅(xin)(xin)防銹的(de)厚度(du),可(ke)保(bao)持(chi)(chi)50年以上(shang)而不必修(xiu)補;在(zai)(zai)市區(qu)或近海(hai)區(qu)域(yu),標準(zhun)的(de)熱鍍(du)(du)(du)鋅(xin)(xin)防銹層(ceng)(ceng)則可(ke)保(bao)持(chi)(chi)20年而不必修(xiu)補; 3、 可(ke)靠(kao)性好:鍍(du)(du)(du)鋅(xin)(xin)層(ceng)(ceng)與鋼材間是冶金(jin)結(jie)合,成為(wei)鋼表面(mian)的(de)一部(bu)份,因此鍍(du)(du)(du)層(ceng)(ceng)的(de)持(chi)(chi)久(jiu)性較(jiao)為(wei)可(ke)靠(kao); 4、 鍍(du)(du)(du)層(ceng)(ceng)的(de)韌性強:鍍(du)(du)(du)鋅(xin)(xin)層(ceng)(ceng)形成一種(zhong)特別的(de)冶金(jin)結(jie)構(gou),這種(zhong)結(jie)構(gou)能承受在(zai)(zai)運送及使用(yong)時(shi)(shi)受到(dao)機械損傷; 5、 全(quan)面(mian)性保(bao)護:鍍(du)(du)(du)件的(de)每一部(bu)分都能鍍(du)(du)(du)上(shang)鋅(xin)(xin),即使在(zai)(zai)凹(ao)陷處(chu)、尖(jian)角及隱(yin)藏(zang)處(chu)都能全(quan)面(mian)地受到(dao)保(bao)護; 6、 省(sheng)時(shi)(shi)省(sheng)力:鍍(du)(du)(du)鋅(xin)(xin)過程要比(bi)其他涂層(ceng)(ceng)的(de)施(shi)工法更快捷(jie),并且可(ke)避免安裝(zhuang)后在(zai)(zai)工地上(shang)涂刷所需的(de)時(shi)(shi)間。
