I-Octafluorocyclobutane (C4F8)

Iiparamitha zobuGcisa

Octafluorocyclobutanei-chemical substance, i-perfluorinated derivative ye-cyclobutane, kunye ne-chemical formula yayo yi-C4F8. Irhasi engenambala, engenavumba, engatshiyo. Izinzile kwindalo kwaye ayinayo ityhefu. Kwimeko yokushisa okuphezulu, uxinzelelo lwangaphakathi lwesitya luya kwanda, kwaye kuya kubakho umngcipheko wokuqhaqha kunye nokuqhuma. Imveliso yokutsha (ukubola) yihydrogen fluoride. I-Octafluorocyclobutane izinzile kwaye ayifuni kunye nezinye izinto phantsi kweemeko eziqhelekileyo. Ukugcinwa kunye nesitya sokuphendula singenziwa ngentsimbi etyhidiweyo kunye nensimbi engenasici kwi-120 ° C, kunye nentsimbi ingasetyenziselwa kwi-175 ° C. Xa ingaphezulu kwe-400 ° C, i-Inconel Materials ezifana ne-nickel kunye neplatinam nazo zinokonakala kancinci. Kwi-500 ° C, ezi zixhobo zinefuthe elibangela ukubola. Kwiqondo lokushisa eliphezulu (600 ° C), i-octafluorocyclobutane inokubola kwikhabhoni, i-carbon tetrafluoride kunye ne-toxic compounds. I-Octafluorocyclobutane inoluhlu olubanzi kakhulu lwezicelo. Kwiminyaka yakutshanje, ibisetyenziswa ngokubanzi njengefriji yokutshintsha iikhompawundi zeklorofluorocarbon ezalelweyo. Ukongeza, ikwasetyenziswa ngokuqhelekileyo kwimithombo yeendaba yokugquma igesi, izinyibilikisi, izitshizi, iiarhente ezikhupha amagwebu, kunye neetchants zesekethe ezinkulu. , Ukufudumeza impompo yokusebenza kwamanzi kunye nezixhobo zokuvelisa i-C2F4 kunye ne-C3F6 monomers. Ucoceko oluphezulu lwe-octafluorocyclobutane (ngaphezu kwe-5N) lusetyenziswa njenge-etching agent kunye ne-arhente yokucoca kwiisekethe ze-VLSI. Ngenxa yezakhiwo zayo ezizinzile, i-non-toxicity, i-zero ye-ozone yokunciphisa amandla (i-ODP), kunye ne-insulation enhle, i-octafluorocyclobutane isetyenziswe ngokubanzi kwiinkalo zobugcisa ezifana ne-high-voltage insulation, ukucocwa kunye ne-etching, kunye nonyango lwe-plasma kwiminyaka yamuva. Impendulo engxamisekileyo ekuvuzeni kwamanzi: nxiba izixhobo zokuphefumla ezizimeleyo kunye nempahla yokusebenza. Sika umthombo werhasi. Ukungenisa umoya kunye ne-convection, i-dilution kunye nokusabalalisa. Hambisa isikhongozeli esivuzayo kwindawo evulekileyo kwaye ubeke ingqalelo ekungeneni komoya. Izikhongozeli ezivuzayo azinakuphinda zisetyenziswe, kwaye kufuneka zinyangwe ngobuchule ukuze kususwe irhasi eseleyo.

Isicelo:

① Ishishini lokutya:

isetyenziswa ikakhulu njengearhente yokutshiza kushishino lokutya, ifriji.

② Umzi mveliso woMbane:

I-enchant yesekethe edibeneyo, ikwasetyenziswa njengomxube we-dielectric kunye ne-sf6, kunye noncedo lwe-polymerization kwikhompawundi ene-fluorinated.

Iphakheji eqhelekileyo:

I-advanteji:

① Ngaphezu kweminyaka elishumi kwimarike;

②ISO umenzi wesatifikethi;

③Ukuhanjiswa okukhawulezayo;
