IArgon ayinayo ityhefu kwaye ayinabungozi ebantwini?

Ubunyulu obuphezuluiargonkunye ne-ultra-pureiargonziigesi ezinqabileyo ezisetyenziswa kakhulu kushishino. Ubume bayo abusebenzi kakhulu, ayitshisi okanye ixhase ukutsha. Kwimveliso yeenqwelomoya, ukwakhiwa kweenqanawa, kushishino lwamandla e-athomu kunye namacandelo eshishini loomatshini, xa udiza izimbiwa ezikhethekileyo, ezifana ne-aluminium, i-magnesium, ubhedu kunye ne-alloys yayo, kunye nentsimbi engatyiwayo, i-argon isoloko isetyenziswa njengegesi yokugcinwa kwe-welding ukuthintela iinxalenye ze-welding ukuba zibe oxidized. okanye i-nitridated emoyeni.

Ngokumalunga nokunyibilika kwesinyithi, ioksijini kunyeiargonukuvuthela ngamanyathelo abalulekileyo okuveliswa kwentsimbi ephezulu. Ukusetyenziswa kwe-argon ngetoni yentsimbi yi-1-3m3. Ukongeza, ukunyibilikiswa kweentsimbi ezikhethekileyo ezifana ne-titanium, i-zirconium, i-germanium, kunye neshishini le-elektroniki likwafuna i-argon njengegesi yokugcina.

I-argon ye-0.932% equlethwe emoyeni inendawo yokubilisa phakathi kwe-oksijeni kunye ne-nitrogen, kwaye umxholo ophezulu phakathi kwenqaba kwisityalo sokuhlukanisa umoya ubizwa ngokuba yi-argon fraction. Yahlula ioksijini kunye nenitrogen kunye, ukhuphe iqhezu le-argon, kwaye uhlukane ngakumbi kwaye uhlambulule, unako ukufumana i-argon ngemveliso. Kuzo zonke izixhobo zokwahlula umoya ophantsi koxinzelelo, ngokuqhelekileyo i-30% ukuya kwi-35% ye-argon emoyeni wokucubungula inokufumaneka njengemveliso (inkqubo yamva nje inokunyusa izinga lokutsalwa kwe-argon ukuya ngaphezu kwe-80%); kuxinzelelo oluphakathi lwezixhobo zokwahlula umoya, ngenxa yokwandiswa komoya Ukungena kwinqaba esezantsi akuchaphazeli inkqubo yokulungiswa kwenqaba ephezulu, kwaye isantya sokutsalwa kwe-argon sinokufikelela malunga ne-60%. Nangona kunjalo, umthamo womoya wokucubungula uwonke wezixhobo ezincinci zokwahlula umoya zincinci, kwaye inani le-argon elinokuveliswa lilinganiselwe. Ingaba kuyimfuneko ukuqwalasela izixhobo zokutsalwa kwe-argon kuxhomekeke kwiimeko ezithile.

Argonyigesi engasebenziyo kwaye ayinawo umonakalo ngqo kumzimba womntu. Nangona kunjalo, emva kokusetyenziswa kwemizi-mveliso, igesi yokukhupha eveliswayo iya kubangela umonakalo omkhulu kumzimba womntu, kubangele i-silicosis kunye nomonakalo wamehlo.

Nangona iyirhasi engasebenziyo, ikwayigesi efuthaniselayo. Ukuphefumla umthamo omkhulu kunokubangela ukuphefumla. Indawo yokuvelisa kufuneka ifakwe umoya, kwaye amagcisa abandakanyeka kwigesi ye-argon kufuneka abe neemviwo rhoqo zezifo zomsebenzi rhoqo ngonyaka ukuqinisekisa impilo yabo.

Argonyona ngokwayo ayinayo ityhefu, kodwa inefuthe lokufunxa kwiindawo eziphezulu. Xa ukuxinwa kwe-argon emoyeni kuphezulu kune-33%, kukho ingozi yokuphefumula. Xa i-argon concentration idlula i-50%, iimpawu ezinzima ziya kubonakala, kwaye xa ugxininiso lufikelela kwi-75% okanye ngaphezulu, lunokufa phakathi kwemizuzu embalwa. I-argon yolwelo inokulimaza ulusu, kwaye ukudibana kwamehlo kunokubangela ukuvuvukala.
