Octafluorocyclobutane (C4F8)

Technical Parameters

Octafluorocyclobutanendi mankhwala, perfluorinated yochokera ku cyclobutane, ndipo mankhwala ake ndi C4F8. Gasi wopanda mtundu, wopanda fungo, wosapsa. Wokhazikika mwachilengedwe komanso wopanda poizoni. Pakatentha kwambiri, kupanikizika kwa mkati mwa chidebecho kudzawonjezeka, ndipo padzakhala chiopsezo chosweka ndi kuphulika. Chowotcha (kuwola) ndi hydrogen fluoride. Octafluorocyclobutane ndi yokhazikika kwambiri ndipo samachita ndi zinthu zina pansi pazikhalidwe zabwino. Chotengera chosungirako ndi chotengera chikhoza kupangidwa ndi chitsulo chosapanga dzimbiri ndi chitsulo chosapanga dzimbiri pa 120 ° C, ndipo chitsulo chingagwiritsidwe ntchito pa 175 ° C. Ikadutsa 400 ° C, Zida za Inconel monga, nickel ndi platinamu zimathanso kuwonongeka pang'ono. Pa 500 ° C, zipangizozi zimakhala ndi mphamvu zowonongeka. Pa kutentha kwambiri (600 ° C), octafluorocyclobutane ikhoza kuwola kukhala carbon, carbon tetrafluoride ndi mankhwala oopsa. Octafluorocyclobutane ali ndi ntchito zosiyanasiyana. M'zaka zaposachedwa, wakhala akugwiritsidwa ntchito kwambiri ngati firiji m'malo mwa mankhwala oletsedwa a chlorofluorocarbon. Kuphatikiza apo, amagwiritsidwanso ntchito kwambiri pamagetsi otchingira mpweya, zosungunulira, zopopera, zotulutsa thovu, ndi ma etchants akulu akulu. , Kutentha mpope ntchito madzimadzi ndi zopangira kupanga C2F4 ndi C3F6 monomers. High-purity octafluorocyclobutane (pamwamba pa 5N) imagwiritsidwa ntchito ngati etching agent ndi kuyeretsa mabwalo a VLSI. Chifukwa cha kukhazikika kwake, kusakhala ndi poizoni, kutha kwa zero ozoni (ODP), komanso kutsekemera kwabwino, octafluorocyclobutane yakhala ikugwiritsidwa ntchito kwambiri m'magawo aukadaulo monga kusungunula kwamphamvu kwambiri, kuyeretsa ndi kuyika, komanso chithandizo cha plasma m'zaka zaposachedwa. Kuyankha mwadzidzidzi pakutayikira: valani zida zopumira zokha komanso zovala zogwirira ntchito. Dulani gwero la gasi. Mpweya wabwino ndi convection, dilution ndi kufalikira. Sunthani chidebe chomwe chikuchucha pa malo otseguka ndipo samalani ndi mpweya wabwino. Zotengera zotayikira sizingagwiritsidwenso ntchito, ndipo ziyenera kuchitidwa mwaukadaulo kuti muchotse mpweya wotsalawo.

Ntchito:

① Makampani a Chakudya:

amagwiritsidwa ntchito ngati kupopera mbewu mankhwalawa m'makampani azakudya, refrigerant.

② Makampani Amagetsi:

enchant for Integrated circuit, idagwiritsidwanso ntchito ngati dielectric blend ndi sf6, ndi polymerization aid pa fluorinated compound.

Phukusi labwinobwino:

Ubwino:

①Kupitilira zaka khumi pamsika;

② ISO wopanga satifiketi;

③Kutumiza mwachangu;

④Stable zopangira gwero;

⑤Dongosolo lowunikira pa intaneti pakuwongolera kwamtundu uliwonse;

⑥Kufunika kwakukulu komanso kusamala pogwira silinda musanadzaze;
