I-nitrogen (N2)

Imingcele yezobuchwepheshe

I-nitrogen (N2) yakha ingxenye enkulu yomkhathi womhlaba, ibalwa ku-78.08% wengqikithi. Ayinambala, ayinaphunga, ayinambitheki, ayinabuthi futhi icishe ibe yigesi engasebenzi ngokuphelele. I-nitrogen ayishi futhi ithathwa njengegesi encisha umoya (okungukuthi, ukuphefumula i-nitrogen ehlanzekile kuzophuca umzimba womuntu umoya-mpilo). I-nitrogen ayisebenzi ngamakhemikhali. Ingasabela nge-hydrogen ukuze yenze i-ammonia ngaphansi kwezinga lokushisa eliphezulu, ukucindezela okuphezulu nezimo ezikhuthazayo; ingahlangana ne-oxygen ukuze yakhe i-nitric oxide ngaphansi kwezimo zokukhishwa. I-nitrogen ivame ukubizwa ngokuthi igesi ye-inert. Isetshenziswa emimoyeni ethile engasebenzi kahle ukuze kusetshenziswe insimbi kanye nama-bulb ukuze kuvinjwe i-arcing, kodwa ayisebenzi ngamakhemikhali. Iyingxenye ebalulekile empilweni yezitshalo nezilwane, futhi iyingxenye yezinhlanganisela eziningi eziwusizo. I-nitrogen ihlangana nezinsimbi eziningi ukwenza ama-nitride aqinile, angasetshenziswa njengezinsimbi ezingagugi. Inani elincane le-nitrogen ensimbi lizovimbela ukukhula okusanhlamvu emazingeni okushisa aphezulu futhi lizokwandisa amandla ezinsimbi ezithile. Ingasetshenziswa futhi ukukhiqiza izindawo eziqinile ensimbi. I-nitrogen ingasetshenziswa ukwenza i-ammonia, i-nitric acid, i-nitrate, i-cyanide, njll; ekwakhiweni kweziqhumane; ukugcwalisa ama-thermometers aphezulu, ama-incandescent bulb; ukwakha izinto ze-inert zokulondoloza izinto, ezisetshenziswa emabhokisini okomisa noma izikhwama zamagilavu. I-nitrogen ewuketshezi ngesikhathi sokuqandisa ukudla; esetshenziswa njengesipholisa elabhorethri. I-nitrogen kufanele igcinwe iqondile endaweni engenawo umoya, ephephile futhi engenaso isimo sezulu, futhi izinga lokushisa lokulondoloza akufanele libe ngaphezu kuka-52°C. Akufanele kube khona izinto ezivutha umlilo endaweni yokugcina futhi uqhelelane nezindawo zokungena nokuphuma njalo nezindawo zokuphuma eziphuthumayo, futhi kungabikho usawoti noma ezinye izinto ezigqwalayo. Kumasilinda egesi angasetshenzisiwe, i-valve cap kanye ne-valve yokuphuma kufanele ivalwe kahle, futhi amasilinda angenalutho kufanele agcinwe ngokuhlukana namasilinda agcwele. Gwema isitoreji esiningi kanye nesikhathi eside sokulondoloza, futhi ugcine amarekhodi amahle okulondoloza.

Isicelo:

①Ezisetshenziswa ezihlukahlukene zokuhlaziya:

Igesi yenkampani yenethiwekhi ye-chromatography yegesi, igesi yokusekela ye-Electron Capture Detectors, i-Liquid Chromatography Mass Spectrometry, igesi yokuhlanza ye-Inductive Couple Plasma.

②Okubalulekile:

1. Ukugcwalisa izibani.
2. Emkhathini we-antibacterial kanye nezingxube zezinsimbi zokusetshenziswa kwezinto eziphilayo .
3. Njengengxenye ye-Controlled Atmosphere Packaging and Modified Atmosphere Packaging applications, 4. Izingxube zegesi yokulinganisa yezinhlelo zokuqapha imvelo, izingxube zegesi ye-laser.
5. Ukufaka ukusabela kwamakhemikhali okuningi komisa imikhiqizo ehlukahlukene noma izinto zokwakha.

③I-nitrogen ewuketshezi:

Njengeqhwa elomile, ukusetshenziswa okuyinhloko kwe-nitrogen ewuketshezi kufana nesiqandisi.

Iphakheji evamile:

Inzuzo:

① Ngaphezu kweminyaka eyishumi emakethe;

②ISO umenzi wesitifiketi;

③Ukulethwa okusheshayo;

④Umthombo wezinto ezingavuthiwe ozinzile;

⑤Isistimu yokuhlaziya eku-inthanethi yokulawula ikhwalithi kuso sonke isinyathelo;

⑥Isidingo esiphezulu kanye nenqubo yokucophelela yokuphatha isilinda ngaphambi kokugcwalisa;
