I-Octafluorocyclobutane (C4F8)

Imingcele Yezobuchwepheshe

I-Octafluorocyclobutaneiyikhemikhali, i-perfluorinated derivative ye-cyclobutane, futhi ifomula yayo yamakhemikhali ithi C4F8. Igesi engenambala, engenaphunga, engashi. Izinzile ngokwemvelo futhi ayinabo ubuthi. Uma kwenzeka ukushisa okuphezulu, ukucindezelwa kwangaphakathi kwesitsha kuzokwanda, futhi kuzoba nengozi yokuqhekeka nokuqhuma. Umkhiqizo wokushiswa (ukubola) yi-hydrogen fluoride. I-Octafluorocyclobutane izinzile kakhulu futhi ayiphenduli nezinye izinto ngaphansi kwezimo ezijwayelekile. Isitsha sokugcina nokusabela singenziwa ngensimbi eyinsimbi nensimbi engagqwali ku-120 ° C, futhi insimbi ingasetshenziswa ku-175 ° C. Uma idlula ku-400°C, Izinto ze-Inconel ezifana ne-nickel neplatinamu nazo zingalimala kancane. Ku-500°C, lezi zinto ezisetshenziswayo zinomthelela wokubola. Emazingeni okushisa aphezulu (600 ° C), i-octafluorocyclobutane ingabola ibe yikhabhoni, i-carbon tetrafluoride kanye nezinhlanganisela ezinobuthi. I-Octafluorocyclobutane inohlu olubanzi kakhulu lwezinhlelo zokusebenza. Eminyakeni yamuva nje, ibisetshenziswa kabanzi njengesiqandisi esikhundleni sezinhlanganisela ezingavunyelwe ze-chlorofluorocarbon. Ngaphezu kwalokho, ibuye isetshenziswe ngokujwayelekile emithonjeni yokuvikela igesi, izincibilikisi, izifutho, ama-ejenti akhipha amagwebu, nezinsimbi ezinkulu zesekethe. , Uketshezi olusebenzayo lwepompo lokushisa kanye nezinto zokusetshenziswa zokukhiqiza ama-monomers e-C2F4 ne-C3F6. I-high-purity octafluorocyclobutane (ngaphezulu kuka-5N) isetshenziswa njenge-etching agent kanye ne-ejenti yokuhlanza yamasekhethi e-VLSI. Ngenxa yezindawo zayo ezizinzile, ukungabi nobuthi, amandla okunciphisa i-ozone (i-ODP), kanye nokufakwa kahle, i-octafluorocyclobutane iye yasetshenziswa kabanzi emikhakheni yezobuchwepheshe efana nokufakwa kwe-voltage ephezulu, ukuhlanza nokufaka, kanye nokwelashwa kwe-plasma eminyakeni yamuva. Ukusabela okuphuthumayo ekuvuzeni: gqoka amathuluzi okuphefumula azimele kanye nezingubo zokusebenza. Sika umthombo wegesi. I-ventilation kanye ne-convection, i-dilution kanye nokusabalalisa. Hambisa isitsha esivuzayo endaweni evulekile futhi unake umoya omncane. Iziqukathi ezivuzayo ngeke zisasetshenziswa, futhi kufanele ziphathwe ngobuchwepheshe ukuze kukhishwe igesi esele.

Isicelo:

① Imboni Yokudla:

isetshenziswa kakhulu njenge-ejenti yokufafaza embonini yokudla, efrijini.

② Imboni Yezogesi:

i-enchant yesekethe ehlanganisiwe, iphinde yasetshenziswa njengengxube ye-dielectric ne-sf6, kanye nosizo lwe-polymerization lwenhlanganisela e-fluorinated.

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;
