氮氣(qi)(qi)(qi)(qi)(qi)在(zai)(zai)社會經(jing)濟各領(ling)域的(de)(de)(de)應(ying)用(yong)(yong)(yong)(yong)日益廣(guang)泛。氮的(de)(de)(de)主要(yao)用(yong)(yong)(yong)(yong)途(tu)是維持(chi)氣(qi)(qi)(qi)(qi)(qi)體，清除氣(qi)(qi)(qi)(qi)(qi)體，載(zai)氣(qi)(qi)(qi)(qi)(qi)，高(gao)純氬(ya)氣(qi)(qi)(qi)(qi)(qi)，干燥氣(qi)(qi)(qi)(qi)(qi)體等(deng)(deng)。氮氣(qi)(qi)(qi)(qi)(qi)作(zuo)為(wei)保持(chi)氣(qi)(qi)(qi)(qi)(qi)體，在(zai)(zai)整個(ge)金(jin)屬(shu)材(cai)料(liao)熱處(chu)理方法(fa)過程中(zhong)(zhong)，對(dui)提(ti)高(gao)金(jin)屬(shu)復合材(cai)料(liao)、零件(jian)的(de)(de)(de)質量、光(guang)滑(hua)度等(deng)(deng)都有直接作(zuo)用(yong)(yong)(yong)(yong)。氬(ya)氣(qi)(qi)(qi)(qi)(qi)主要(yao)是用(yong)(yong)(yong)(yong)于(yu)(yu)燈泡充氣(qi)(qi)(qi)(qi)(qi)和對(dui)不(bu)銹鋼(gang)、鎂、鋁等(deng)(deng)的(de)(de)(de)電(dian)(dian)弧焊接，即'氬(ya)弧焊'。還用(yong)(yong)(yong)(yong)于(yu)(yu)鋼(gang)鐵、鋁、鈦和鋯的(de)(de)(de)冶(ye)煉中(zhong)(zhong)。放電(dian)(dian)時氬(ya)發(fa)出(chu)紫色輝光(guang)，又用(yong)(yong)(yong)(yong)于(yu)(yu)照明技術和填充日光(guang)燈、光(guang)電(dian)(dian)管(guan)、照明管(guan)等(deng)(deng)。煉鋼(gang)---用(yong)(yong)(yong)(yong)于(yu)(yu)置換氣(qi)(qi)(qi)(qi)(qi)體或蒸氣(qi)(qi)(qi)(qi)(qi)并(bing)防止工藝(yi)流程中(zhong)(zhong)的(de)(de)(de)氧化；用(yong)(yong)(yong)(yong)于(yu)(yu)攪拌(ban)鋼(gang)水來保持(chi)恒定的(de)(de)(de)溫度和同一的(de)(de)(de)成份；在(zai)(zai)脫氣(qi)(qi)(qi)(qi)(qi)過程中(zhong)(zhong)幫助(zhu)去除不(bu)需要(yao)的(de)(de)(de)可溶氣(qi)(qi)(qi)(qi)(qi)體。

放(fang)電時氬(ya)(ya)發出紫色輝光(guang)，又用(yong)于照(zhao)明技術和填充日光(guang)燈、光(guang)電管、照(zhao)明管等。熱(re)處理工藝也(ye)用(yong)于代替氮氣(qi)(qi)和氨氣(qi)(qi)，氬(ya)(ya)氣(qi)(qi)哪家好，效(xiao)果(guo)更是超過氮氣(qi)(qi)和氨氣(qi)(qi)，不銹鋼熱(re)處理時采(cai)用(yong)氬(ya)(ya)氣(qi)(qi)保護折(zhe)彎效(xiao)果(guo)更好不易(yi)斷裂。氬(ya)(ya)本身(shen)***，但在高濃度時有窒(zhi)息(xi)作用(yong)。當空氣(qi)(qi)中(zhong)氬(ya)(ya)氣(qi)(qi)濃度高于33%時，即氧(yang)氣(qi)(qi)濃度比平時減少2/3以(yi)下(xia)時，就(jiu)有窒(zhi)息(xi)的(de)危險。氬(ya)(ya)氣(qi)(qi)的(de)用(yong)途(tu)：雙(shuang)層(ceng)玻璃窗(chuang)氬(ya)(ya)氣(qi)(qi)使用(yong)，以(yi)填補(bu)窗(chuang)格之間的(de)空間，豪華車的(de)輪(lun)胎可(ke)以(yi)包含(han)氬(ya)(ya)氣(qi)(qi)保護橡膠，降低路面(mian)噪(zao)音。

 氬(ya)(ya)氣(qi)(qi)(qi)瓶上應貼有工廠合格的(de)(de)(de)標簽，其(qi)純(chun)(chun)度≥99.95％。氣(qi)(qi)(qi)瓶中(zhong)的(de)(de)(de)氬(ya)(ya)氣(qi)(qi)(qi)不(bu)能用(yong)完，純(chun)(chun)氬(ya)(ya)氣(qi)(qi)(qi)，并且氣(qi)(qi)(qi)瓶中(zhong)的(de)(de)(de)殘(can)余壓力不(bu)得(de)小(xiao)于(yu)0.5MPa，以確保(bao)充入氬(ya)(ya)氣(qi)(qi)(qi)的(de)(de)(de)純(chun)(chun)度。 工業氬(ya)(ya)氣(qi)(qi)(qi)電燈(deng)(deng)泡里的(de)(de)(de)填充氣(qi)(qi)(qi)體，由于(yu)氬(ya)(ya)氣(qi)(qi)(qi)不(bu)會(hui)與(yu)燈(deng)(deng)芯(xin)產生化學(xue)反響，而又能堅(jian)持氣(qi)(qi)(qi)壓減緩鎢絲(si)升華，可(ke)延長燈(deng)(deng)絲(si)運用(yong)壽(shou)命，氬(ya)(ya)可(ke)當作(zuo)焊(han)(han)(han)(han)接(jie)時(shi)(shi)所用(yong)的(de)(de)(de)維護(hu)氣(qi)(qi)(qi)體，其(qi)中(zhong)包括MIG焊(han)(han)(han)(han)接(jie)、GTA焊(han)(han)(han)(han)接(jie)與(yu)GMA焊(han)(han)(han)(han)接(jie)等(deng)，淮北氬(ya)(ya)氣(qi)(qi)(qi)，在這時(shi)(shi)氬(ya)(ya)通常會(hui)和二氧化碳混合在一同運用(yong)。氬(ya)(ya)氣(qi)(qi)(qi)的(de)(de)(de)種(zhong)類(lei)(lei)分類(lei)(lei)很多，不(bu)僅僅能進行單獨的(de)(de)(de)全(quan)氬(ya)(ya)焊(han)(han)(han)(han)接(jie)。在氣(qi)(qi)(qi)保(bao)焊(han)(han)(han)(han)，等(deng)離(li)子(zi)焊(han)(han)(han)(han) 和富氬(ya)(ya)焊(han)(han)(han)(han)接(jie)中(zhong)也參(can)與(yu)其(qi)中(zhong)。今天(tian)我們看下這些氬(ya)(ya)氣(qi)(qi)(qi)是如何被應用(yong)在里面中(zhong)參(can)與(yu)焊(han)(han)(han)(han)接(jie)的(de)(de)(de)。
