chifukwa chiyani argon ndi gasi wa inert?
1. Chifukwa chiyani argon ndi chinthu cha inert?
Zomwe zimatchedwa "inert inert gas" zimatanthawuza kuti mipweyayi imakhala yokhazikika kwambiri, imakhala ndi reactivity yochepa, ndipo sizovuta kupanga mankhwala ndi mpweya. Ndipotu, "inertia" ya argon zitha kuwoneka patebulo la periodic. Argon ali mu gulu ziro mu periodic tebulo la zinthu. Chigoba chakunja cha atomu chili ndi ma elekitironi asanu ndi atatu, omwe amapanga chokhazikika. Mankhwala ake sagwira ntchito kwambiri. Argon, haidrojeni, neon, krypton, xenon, ndi radon nawonso ndi mpweya wabwino.
2. Chifukwa chiyani argon ndi helium amatchedwa mpweya wabwino?
Dongosolo la mpweya wa inert limatanthawuza argon (Ar), helium (He), neon (Ne), krypton (kr), xenon, (xe) ndi radon (Rn), chifukwa cha mankhwala osagwira ntchito, zimakhala zovuta kuchitapo kanthu ndi zinthu zina zomwe zimachitika, choncho amatchedwa mpweya wa inert. Popeza zomwe zili m'mipweya isanu ndi umodziyi mumlengalenga ndi zosakwana 1%, zimatchedwanso mpweya wosowa.
Mu Chigriki, argon amatanthauza "ulesi", kotero anthu amagwiritsa ntchito inertness ya gasi ngati mpweya wotetezera muzitsulo zowotcherera ndi kudula kuti zisawonongeke. The chemical inertness ya argon imagwiritsidwanso ntchito posungunula zitsulo zapadera. Kuwombera ndi kuteteza argon ndi njira yofunikira yopititsira patsogolo chitsulo. Chifukwa mpweya wa argon uli ndi kachulukidwe kakang'ono kwambiri komanso kutsika kwamafuta otsika, kudzaza mu babu kumatha kukhazikitsanso moyo wa babu ndikuwonjezera kuwala, motero mpweya wa argon umagwiritsidwa ntchito pamakampani owunikira ndikudzaza ma discharger osiyanasiyana, komanso amagwiritsidwa ntchito mu lasers ndi mfuti yopopera ya hemostasis. Argon angagwiritsidwe ntchito ngati mpweya chonyamulira mu chromatographs lalikulu.
Helium amatanthauza "dzuwa" mu Chigriki, kotero. Helium poyamba ankatchedwa "solar matter". Ndi gasi wofunikira kwambiri wamakampani. Ndi chitukuko chaukadaulo wa inki yotsika kwambiri, helium yakhala chinthu chofunikira kwambiri, ndipo ikukhala yofunika kwambiri. Helium imagwiritsidwa ntchito poyerekezera chilengedwe chamlengalenga ndikuyambitsa miyala: helium imagwiritsidwa ntchito popanga zida za nyukiliya ndi bomba la atomiki; Ukadaulo wozindikira ma infrared ndi zida zamagetsi zotsika kutentha Kugwiritsa ntchito mwaukadaulo kwa helium kumathandizira kuti ikwaniritse chidwi chachikulu komanso kulondola kwambiri.
3. Kodi pali kusiyana kotani pakati pa mpweya wabwino ndi mpweya wochepa?
Mipweya yosowa (helium, neon, argon, krypton, xenon, nitrogen,) ndi mpweya wa inert, kusiyana kwake: chiwerengero cha ma elekitironi mu chipolopolo chakunja cha mpweya wosowa ndi onse (neon 2 ndi kunja), ndipo samachita ndi zinthu zina.
4. Kodi pali kusiyana kotani pakati pa mpweya wa inert ndi mpweya wotuluka?
Mipweya ya inert ndi helium ndi argon, zomwe sizimakhudzidwa konse ndi chitsulo chosungunula chowotcherera ndipo zimagwiritsidwa ntchito powotcherera MIG (zitsulo-inert gas arc welding). Mipweya yowonongeka nthawi zambiri imakhala carbon dioxide, oxygen, nitrogen ndi hydrogen. Mipweya iyi imagwira nawo ntchito yowotcherera pokhazikitsa arc ndikuwonetsetsa kuti zinthu zikuyenda bwino pakuwotcherera. Zikakhala zochulukirapo, zimatha kuwononga weld, koma pang'ono zimatha kusintha mawonekedwe awotcherera. Amagwiritsidwa ntchito powotcherera MAG (Metal-Activated Gas Arc Welding).
Mpweya wa inert nthawi zambiri umakhala mpweya womwe sukumana ndi mankhwala, monga nayitrogeni.
Mipweya yotulutsa mpweya ndi mipweya yomwe imagwira ntchito mosavuta, monga mpweya. haidrojeni.
Mu oceanography, mipweya isanu ya inert monga helium, neon, argon, krypton, ndi xenon, ndi nayitrogeni amatchedwa mpweya wa inert. Amatchedwanso mpweya wodziletsa. Chifukwa kagawidwe ndi kusiyanasiyana kwa mipweya imeneyi m'nyanja zambiri zimatsimikiziridwa makamaka ndi zochitika zosiyanasiyana zakuthupi ndi chikoka cha kutentha ndi mchere pa kusungunuka kwake. Kuphatikiza pa mipweya yomwe ili pamwambayi, yomwe imatchedwanso kuti ma reactive gases (onani mpweya wotuluka), imakhudzidwanso ndi zinthu monga biogeochemistry.
Nayitrogeni wosungunuka m'nyanja sikugwirizana kwathunthu ndi njira zamoyo. Njira zina zachilengedwe zimatha kusintha nayitrogeni kukhala nayitrogeni wa organic, kenako kukhala nitrate. Pansi pazikhalidwe za anaerobic, nayitrogeni imatha kutulutsidwanso pamene zinthu za organic zapangidwa ndi okosijeni ndikuwola chifukwa cha mabakiteriya.
5. Kodi kuopsa kwa mpweya wabwino ndi kotani?
Mipweya ya inert ndi yopanda mtundu komanso yopanda fungo. Mipweya ya inert monga nayitrogeni, argon, ndi helium nthawi zambiri imawonedwa ngati yopanda vuto, kotero palibe kusamala pang'ono kapena kulibe chitetezo. Zosiyana ndi zowona. Popeza mipweya ya inert sadziwika ndi mphamvu za munthu, imatha kukhala yowopsa kuposa mpweya wapoizoni wokhala ndi fungo lamphamvu (monga ammonia, hydrogen sulfide, ndi sulfure dioxide), zomwe zimazindikirika mwachangu ndi thupi la munthu ngakhale m'malo ochepa.
Palibe zizindikiro zoyamba za kupuma kwa gasi, kotero palibe chidziwitso chomwe chingaperekedwe kwa wozunzidwayo kapena omwe ali pafupi. Kuperewera kwa okosijeni kungayambitse chizungulire, kupweteka kwa mutu kapena kulankhula koma ozunzidwa nthawi zambiri samagwirizanitsa chizindikirochi ndi kutsamwitsidwa. Ngati mpweya wa okosijeni uli wochepa kwambiri, anthu ovutika akhoza kukomoka akapuma pang'ono.
Ngozi iliyonse ya cerebral hypoxia imafuna chithandizo chamankhwala mwamsanga. Komabe, ozunzidwa amatha kuvulala kwambiri muubongo mpaka kufa kumene. Choncho, cholakwika chofala ndi chakuti ogwira nawo ntchito amayesa kupulumutsa munthu amene wagwa ndi dzanja popanda kuyang'ana momwe zinthu zilili komanso / kapena kugwiritsa ntchito zipangizo zotetezera (ie zipangizo zopumira zokha). Si zachilendo kuti njira zosakonzekera bwino m'makampaniwa zibweretse kupha anthu. Kupuma mpweya umodzi kapena kuŵiri zotsatizana za gasi wosaziziritsa, monga ngati nayitrogeni, ndi mchitidwe wowopsa kwambiri ndipo nthaŵi zambiri kumapangitsa kuti wovulalayo akomoke. Ngati mpweya wa mpweya mu mpweya wozungulira watsika kwambiri, wovulalayo akhoza kufa patangopita mphindi zochepa atakomoka.
6. Kodi mawonekedwe a gasi wa argon ndi ati?
1. Kuwotcherera ndi kudula: Argon imagwiritsidwa ntchito kwambiri muzinthu monga TIG argon arc kuwotcherera, kudula kwa plasma ndi kuwotcherera kwa mpweya wa MIG. Argon angagwiritsidwe ntchito kuteteza maelekitirodi mpweya pa kuwotcherera kuteteza makutidwe ndi okosijeni. 2. Kuunikira: Mu nyali za neon zodzaza ndi argon zodzaza ndi argon ndi magetsi a neon, mphamvu yamagetsi ikadutsa mu nyalizi, imatulutsa kuwala kowoneka ndi maso a munthu, kumapangitsa malo ena kukhala okongola komanso okongola.
3. Kudzaza gasi: Gasi ya Argon ingagwiritsidwe ntchito kudzaza zida zamagetsi ndi zamagetsi kuti zitetezedwe ku mpweya ndi chinyezi, zomwe zimalepheretsa bwino kuwonongeka kwa zigawozo.
4. Pukuta: Argon ingagwiritsidwe ntchito kuyeretsa zida zamagetsi ndi zida zochotsera fumbi ndi dothi.
5. Zachipatala: Gasi wa Argon amagwiritsidwa ntchito pochita opaleshoni, kuthandizira kupuma ndi kufufuza m'magulu azachipatala kuti asunge minofu yaumunthu ikakhazikika.
6. Magalimoto a Hover: Argon ingagwiritsidwenso ntchito ngati madzi ogwira ntchito m'galimoto ya hover, yomwe imalola kuti galimoto yoyendetsa ndege iwonongeke pakati pa mpweya ndi pansi. Pomaliza, argon ili ndi ntchito zofunikira komanso ntchito m'magawo ambiri azamakampani ndi sayansi.
