I-Sulfur Hexafluoride (SF6)

Amapharamitha obuchwepheshe

I-hexafluoride ye-sulfur, ifomula yayo yamakhemikhali eyi-SF6, iyigesi ezinzile engenambala, engenaphunga, engenabuthi, futhi engashi. I-hexafluoride ye-sulfur iyigesi ngaphansi kokushisa okuvamile kanye nengcindezi, inezakhiwo zamakhemikhali ezizinzile, incibilika kancane emanzini, utshwala kanye ne-ether, incibilika ku-potassium hydroxide, futhi ayisebenzi ngamakhemikhali ne-sodium hydroxide, i-ammonia ewuketshezi kanye ne-hydrochloric acid. Ayisebenzi ngethusi, isiliva, insimbi, kanye ne-aluminium endaweni eyomile engaphansi kwama-300°C. Ngaphansi kwama-500℃, ayinawo umthelela ku-quartz. Isebenza nge-sodium yensimbi ku-250°C, futhi isebenza nge-ammonia ewuketshezi ku--64°C. Izobola uma ixutshwe ne-hydrogen sulfide futhi ishiswa. Ku-200℃, lapho kukhona izinsimbi ezithile njengensimbi nensimbi ye-silicon, ingakhuthaza ukubola kwayo kancane. I-hexafluoride ye-sulfur iyisizukulwane esisha sezinto zokuvikela ugesi ezinamandla aphezulu, ezisetshenziswa kabanzi ekuvikeleni igesi kwe-elekthronikhi, imishini kagesi kanye nama-radar waveguides, kanye nezinto zokuvikela ugesi zokucisha i-arc kanye nama-transformer amakhulu kuma-switch ane-voltage ephezulu. Izinzuzo zemigqa yokudlulisela ipayipi elivikela ugesi le-SF6 ukulahleka okuphansi kwe-dielectric, amandla amakhulu okudlulisa, futhi zingasetshenziswa ngezikhathi zokwehla okukhulu. I-transformer evikela ugesi ye-SF6 inezinzuzo zokuvikela umlilo nokuqhuma. I-hexafluoride ye-sulfur inezici zokuqina okuhle kwamakhemikhali kanye nokungagqwali emishinini. Ingasetshenziswa njengesiqandisi embonini yeziqandisi (izinga lokushisa lokusebenza liphakathi kuka--45~0℃). I-hexafluoride ye-sulfur yezinga eliphezulu le-elekthronikhi iyindlela efanelekile yokuvikela ugesi, esetshenziswa kabanzi emkhakheni wobuchwepheshe be-microelectronics njenge-ejenti yokuhlanza i-plasma ekwenziweni kwamasekethe amakhulu ahlanganisiwe njengama-computer chips kanye nezikrini ze-liquid crystal. Izinyathelo zokugcina: Gcina endaweni yokugcina epholile, enomoya. Gcina kude nomlilo kanye nemithombo yokushisa. Izinga lokushisa lokugcina akufanele lidlule ku-30°C. Kufanele ligcinwe ngokwehlukana nezinto ezivuthayo kalula (ezivuthayo) kanye nezinto ezi-oxidants, futhi kugwenywe ukugcinwa okuxubile. Indawo yokugcina kufanele ifakwe imishini yokwelapha ephuthumayo evuzayo.

Isicelo:

①Indawo yokushintshashintsha kwe-dielectric:

I-SF6 isetshenziswa embonini kagesi njengendlela yokusabalalisa igesi yama-circuit breaker ane-voltage ephezulu, ama-switchgear, neminye imishini kagesi, ivame ukuthatha indawo yama-circuit breaker agcwele uwoyela (ama-OCB) angaqukatha ama-PCB ayingozi.

②Ukusetshenziswa kwezokwelapha:

I-SF6 isetshenziselwa ukuhlinzeka nge-tamponade noma i-plug yembobo ye-retinal emisebenzini yokulungisa i-retinal detachment ngendlela yebhamuza legesi.

③Inhlanganisela ye-Tracer:

I-SF6 isetshenziselwa ukuhlinzeka nge-tamponade noma i-plug yembobo ye-retinal emisebenzini yokulungisa i-retinal detachment ngendlela yebhamuza legesi.
