Ingabe kuphephile ukuhogela i-sulphur hexafluoride?
1. Ingabe i-hexafluoride inobuthi?
I-sulphur hexafluoridei-inert ye-physiologically futhi ithathwa njengegesi engasebenzi ku-pharmacology. Kodwa uma iqukethe ukungcola okufana ne-SF4, iba into enobuthi. Lapho uhogela ukugxila okuphezulu kwe-SF6, izimpawu ze-asphyxia ezifana ne-dyspnea, ukukhwehlela, isikhumba esiluhlaza okwesibhakabhaka nolwelwesi lwamafinyila, kanye nokudlikizeka okuvamile.
2. Ingabe i-sulphur hexafluoride yenza izwi lakho libe phansi?
Ukushintsha komsindo wesulphur hexafluoridekumane nje kuphambene nokushintsha komsindo we-helium, futhi umsindo unzima futhi uphansi. Uma i-sulphur hexafluoride ihogelwa, i-sulphur hexafluoride izogcwalisa izintambo zezwi ezizungezile. Lapho senza umsindo nezintambo zezwi zidlidliza, okuqhutshwa ukudlidliza akuwona umoya esivame ukuwukhuluma kodwa i-sulphur hexafluoride. Ngenxa yokuthi isisindo samangqamuzana e-sulphur hexafluoride sikhulu kunesilinganiso sesisindo somoya, imvamisa yokudlidliza iphansi kuneyomoya, ngakho kuzoba nomsindo ojulile futhi omkhulu kunokuvamile.
3. Side kangakanani isikhathi sokufaneleka kwe-sulphur hexafluoride?
Impilo yeshelufu evamile yamabhamuza e-sulphur hexafluoride angaphansi kukaziro unyaka ongu-1.
4. Ingabe i-sulphur hexafluoride yimbi kune-carbon dioxide?
SF6sulphur hexafluoridefuthi igesi elibamba ukushisa elinamandla kakhulu elaziwayo. Uma kuqhathaniswa ne-CO2 carbon dioxide ejwayelekile, amandla e-SF6 sulfur hexafluoride aphindwe izikhathi ezingu-23,500 kune-CO2 carbon dioxide. Ukwengeza, i-SF6 sulfur hexafluoride ayikwazi ukubola ngokwemvelo. Ithonya lingahlala iminyaka engaphezu kwenkulungwane; izici zokushibhile nokusebenziseka kalula, okuhambisana nezici zokukwazi ukuba khona izinkulungwane zeminyaka ngaphandle kokubola kwemvelo, kwenza le gesi ibe ukungcoliswa okunganakiwe nokubi kakhulu "ekuphehleni kwamandla aluhlaza".
5. Ingakanani i-sulphur hexafluoride esindayo kunomoya esiwuphefumulayo?
Igesi ye-SF6 ayinambala, ayinalwazi, ayinabo ubuthi, ayishi, futhi igesi ezinzile. I-SF6 iyigesi enzima uma kuqhathaniswa, enzima izikhathi ezi-5 kunomoya ngaphansi kwezimo ezijwayelekile.
6. Ingabe i-sulphur hexafluoride iyisidakamizwa?
Imiphumela engemihle ye-sulphur hexafluoride emzimbeni womuntu imvamisa ithambile futhi iyisikhathi esifushane, futhi ingalulama ngokuzenzakalelayo ngaphandle kwe-sequelae. I-Sulfur hexafluoride iyisidakamizwa sokuxilonga esisetshenziswa ekuhlolweni kwe-ultrasound imaging, i-echocardiography, nokuhlolwa kwe-vascular Doppler ukuthuthukisa ukuhlonzwa kwesifo. I-Sulfur hexafluoride isetshenziselwa ukuxilongwa kwe-ultrasonic futhi idinga ukusetshenziswa ezikhungweni zezokwelapha ezinezimo eziphuthumayo futhi ifakwe abasebenzi bokuhlenga, futhi idinga ukujovwa udokotela. Uma ukungezwani komzimba kwenzeka ngesikhathi noma ngemva kokusetshenziswa kwe-sulphur hexafluoride, kuzobonakala njenge-erythema yesikhumba, i-bradycardia, i-hypotension ngisho nokushaqeka kwe-anaphylactic. Uma unezimpawu zesistimu nezendawo zokungakhululeki, kufanele wazise udokotela ngokushesha noma uye esibhedlela ukuze uyohlolwa. Ngemuva kokuthatha umuthi, kuyadingeka ukubheka esikhungweni sezokwelapha esifanele isigamu sehora ukuvimbela ukungezwani komzimba. Ukusetshenziswa kwe-sulphur hexafluoride ezigulini ezinesifo senhliziyo kungase kubhebhethekise isifo senhliziyo.
ungakwazi ukuphuza i-liquid carbon dioxide?
