IiPropati zeNitrojeni: Ujongo oluneenkcukacha kwiGesi eBalulekileyo kuShishino lweMichiza
Njengegesi ye-inert eqhelekileyo kwishishini lemichiza, i-nitrogen isetyenziswa ngokubanzi kwiinkqubo ezahlukeneyo zemveliso kunye novavanyo ngenxa yeempawu zayo ezizodwa kunye neekhemikhali. Kweli nqaku, siza kuxubusha iipropati nitrogen ngokweenkcukacha ukukunceda ukuba uqonde ngcono ukubaluleka le gesi kushishino.
I. IiPropati zoMzimba eziSisiseko zeNitrojeni
I-Nitrojeni (N₂) yigesi engenambala, engenavumba kwaye engeyotyhefu kubushushu begumbi kunye noxinzelelo. Ubunzima bayo bemolekyuli yi-28.0134 g/mol kwaye ingxinano yi-1.2506 kg/m³, ekhaphukhaphu kancinane kunomoya. Kwimveliso yemichiza, initrogen idla ngokusetyenziswa ukuvelisa ubume bendawo ezinobushushu obuphantsi ngenxa yeqondo eliphantsi lokubila kwayo (-195.8°C), kwaye initrogen engamanzi isoloko isetyenziswa njengesipholisi. I-solubility ephantsi kunye ne-conductivity ephantsi yombane ye-nitrogen yenza ukuba ibe luncedo kakhulu kwiindawo ezikhethekileyo.
Okwesibini, ukunganyaniseki kweekhemikhali zenitrogen
Enye yezona mpawu zibalulekileyo zenitrogen kukungangeni kwekhemikhali. Kwiqondo lokushisa eliqhelekileyo kunye noxinzelelo, i-molecule ye-nitrogen (N₂) izinzile kakhulu kuba iqulethe ii-athomu ezimbini ze-nitrogen ezidityaniswe yi-triple bond, eyenza ingasebenzi kwiimpendulo ezininzi zeekhemikhali. Le inertness yeekhemikhali inenzuzo kwizicelo ezininzi zemizi-mveliso, umzekelo, xa isetyenziselwa i-welding, ukugcinwa kokutya kunye negesi ekhuselayo ekuphenduleni kweekhemikhali, i-nitrogen ikhusela ngokufanelekileyo i-oxidation, ukutsha kunye nezinye iikhemikhali ezingafunekiyo.
III. Ukhuseleko kunye neempembelelo zokusingqongileyo zenitrogen
Nangona i-nitrogen isetyenziswa kakhulu kwishishini lemichiza, ukhuseleko lwayo isengumbandela obalulekileyo. Nangona initrogen ngokwayo ingeyotyhefu, ukuvuza kwezixa ezikhulu zenitrogen kwindawo evalelweyo kunokukhokelela ekucuthekeni koxinzelelo lweoksijini, nto leyo enokukhokelela kwingozi yokuphefumla. Ngoko ke kubalulekile ukuqinisekisa umoya omhle kunye neenkqubo ezingqongqo zokhuseleko xa usebenzisa i-nitrogen. Njengoko i-nitrogen ayiyi kusabela kunye namanye amacandelo emoyeni, ayinabungozi kwindalo kwaye ayiyi kukhokelela kwi-greenhouse effect okanye itshabalalise i-ozone layer.
IV. Ukusetyenziswa koShishino lweNitrojeni
I-Nitrogen inoluhlu olubanzi lwezicelo kwishishini lemichiza ngenxa yeempawu zayo ezizodwa. Ngokomzekelo, ekuphenduleni kweekhemikhali, i-nitrogen isoloko isetyenziswa njengegesi ye-inert ukukhusela i-oxidation okanye i-hydrolysis ye-reactants; kwishishini lokutya, initrogen isetyenziselwa ukupakishwa kunye nokugcinwa ukwandisa ubomi beshelufu yokutya; kwimveliso ye-elektroniki, initrogen isetyenziselwa ukukhusela amacandelo e-elektroniki abuthathaka ukusuka kumanzi okanye kwi-oxidation.
Isishwankathelo
Ngokuhlalutya iipropati nitrogen ngokweenkcukacha, sinokubona ukuba initrogen yigesi ebalulekileyo kwaye ibalulekileyo kushishino imichiza ngenxa uzinzo emzimbeni kunye inertness imichiza. Ukuqonda kunye nokuqonda iipropathi ze-nitrogen akuncedi kuphela ukusebenza ngokukhuselekileyo, kodwa kuphucula ukusebenza kakuhle kwemveliso yeshishini. Kuphuhliso lwetekhnoloji yexesha elizayo, amandla okusetyenziswa kwenitrogen aya kuqhubeka nokwandisa, ebonelela ngezisombululo ezininzi kumashishini ahlukeneyo.
