Katundu wa Nayitrogeni: Kuyang'ana mwatsatanetsatane pa Gasi Wofunika Pamakampani a Chemical
Monga gasi wamba wamba mumakampani opanga mankhwala, nayitrogeni amagwiritsidwa ntchito kwambiri popanga ndi kuyesa njira zosiyanasiyana chifukwa cha mawonekedwe ake apadera akuthupi ndi mankhwala. M'nkhaniyi, tikambirana za nayitrogeni mwatsatanetsatane kukuthandizani kumvetsetsa kufunikira kwa mpweyawu m'makampani.
I. Katundu Wakuthupi Wa Nayitrogeni
Nayitrojeni (N₂) ndi mpweya wopanda mtundu, wopanda fungo komanso wopanda poizoni pa kutentha ndi kupanikizika. Kulemera kwake ndi 28.0134 g/mol ndipo kachulukidwe ndi 1.2506 kg/m³, yomwe ndi yopepuka pang'ono kuposa mpweya. Popanga mankhwala, nayitrogeni amagwiritsidwa ntchito popanga malo otsika chifukwa cha kuwira kwake kochepa (-195.8 ° C), ndipo nayitrogeni wamadzimadzi amagwiritsidwa ntchito ngati chozizirira. Kusungunuka kochepa komanso kutsika kwamagetsi kwa nayitrogeni kumapangitsa kuti ikhale yothandiza kwambiri m'malo ena apadera.
Chachiwiri, mankhwala inertness wa asafe
Chimodzi mwazinthu zofunika kwambiri za nayitrogeni ndi kusakwanira kwake kwamankhwala. Pa kutentha ndi kupanikizika, molekyulu ya nayitrogeni (N₂) imakhala yokhazikika chifukwa imakhala ndi maatomu awiri a nayitrogeni omwe amalumikizidwa ndi chomangira chapatatu, chomwe chimapangitsa kuti chisagwire ntchito pamakina ambiri. Kusakhazikika kwamankhwala kumeneku kumapindulitsa m'mafakitale ambiri, mwachitsanzo, akagwiritsidwa ntchito powotcherera, kusunga chakudya komanso ngati mpweya woteteza pamachitidwe amankhwala, nayitrogeni imalepheretsa bwino makutidwe ndi okosijeni, kuyaka ndi zinthu zina zosafunikira zamankhwala.
III. Chitetezo ndi chilengedwe cha nayitrogeni
Ngakhale kuti nayitrogeni imagwiritsidwa ntchito kwambiri m'makampani opanga mankhwala, chitetezo chake ndi nkhani yofunika. Ngakhale kuti nayitrogeni weniweniyo siwowopsa, kutayikira kwa nayitrogeni wambiri m'malo otsekeredwa kungayambitse kuchepa kwa mpweya wa okosijeni, zomwe zingayambitse vuto la asphyxiation. Chifukwa chake ndikofunikira kuonetsetsa kuti mpweya wabwino umakhala wabwino komanso njira zotetezeka zotetezedwa mukamagwiritsa ntchito nayitrogeni. Popeza kuti nayitrogeni sichingagwirizane ndi zigawo zina za mumlengalenga, ilibe vuto kwa chilengedwe ndipo sichidzatsogolera ku greenhouse effect kapena kuwononga ozone layer.
IV. Kugwiritsidwa Ntchito kwa Nayitrogeni ku Industrial
Nayitrojeni imagwiritsidwa ntchito mosiyanasiyana pamakampani opanga mankhwala chifukwa cha mawonekedwe ake apadera. Mwachitsanzo, muzochita zamakina, nayitrogeni nthawi zambiri amagwiritsidwa ntchito ngati mpweya wopanda mpweya kuti ateteze oxidation kapena hydrolysis ya reactants; m'makampani azakudya, nayitrogeni amagwiritsidwa ntchito pakuyika ndikusunga kuti awonjezere moyo wa alumali wa chakudya; pakupanga zamagetsi, nayitrogeni amagwiritsidwa ntchito kuteteza zida zamagetsi ku chinyezi kapena okosijeni.
Chidule
Pofufuza mwatsatanetsatane za nayitrogeni mwatsatanetsatane, titha kuwona kuti nayitrogeni ndi mpweya wofunikira komanso wofunikira pamakampani opanga mankhwala chifukwa cha kukhazikika kwake kwakuthupi komanso kusakhazikika kwamankhwala. Kumvetsetsa komanso kudziwa bwino za nayitrogeni sikuti kumangothandiza kugwira ntchito motetezeka, komanso kumathandizira kupanga bwino kwa mafakitale. Pachitukuko chamtsogolo chaukadaulo, mphamvu yogwiritsira ntchito nayitrogeni ipitilira kukula, ndikupereka njira zambiri zamafakitale osiyanasiyana.
