Octafluorocyclobutane (C4F8)

Magawo aukadaulo

Octafluorocyclobutane ndi mankhwala, omwe amachokera ku cyclobutane, ndipo njira yake ya mankhwala ndi C4F8. Mpweya wopanda utoto, wopanda fungo, wosayaka. Wokhazikika mwachilengedwe komanso wopanda poizoni. Pakakhala kutentha kwambiri, kuthamanga kwamkati kwa chidebecho kudzawonjezeka, ndipo padzakhala chiopsezo cha kusweka ndi kuphulika. Chopangidwa ndi kuyaka (kuwola) ndi hydrogen fluoride. Octafluorocyclobutane ndi yokhazikika kwambiri ndipo sichitapo kanthu ndi zinthu zina pansi pa mikhalidwe yabwinobwino. Chotengera chosungiramo ndi chochitapo kanthu chingapangidwe ndi chitsulo chopangidwa ndi chitsulo chosapanga dzimbiri pa 120°C, ndipo chitsulo chingagwiritsidwe ntchito pa 175°C. Chikapitirira 400°C, Zinthu za Inconel monga, nickel ndi platinamu zitha kuwonongeka pang'ono. Pa 500°C, zinthuzi zimakhala ndi mphamvu yothandiza pakuwola. Pa kutentha kwambiri (600°C), octafluorocyclobutane imatha kuwola kukhala kaboni, kaboni tetrafluoride ndi mankhwala oopsa. Octafluorocyclobutane ili ndi ntchito zambiri. M'zaka zaposachedwa, yagwiritsidwa ntchito kwambiri ngati refrigerant kuti ilowe m'malo mwa mankhwala oletsedwa a chlorofluorocarbon. Kuphatikiza apo, imagwiritsidwanso ntchito kwambiri mu zotetezera mpweya, zosungunulira, zopopera, zotulutsa thovu, ndi zotchingira zazikulu. , Madzi ogwirira ntchito pampu yotenthetsera ndi zinthu zopangira popanga ma monomers a C2F4 ndi C3F6. Octafluorocyclobutane yoyera kwambiri (yoposa 5N) imagwiritsidwa ntchito ngati chotsukira ndi chotsukira ma circuits a VLSI. Chifukwa cha makhalidwe ake okhazikika, osakhala poizoni, zero ozone depletion potential (ODP), komanso choteteza bwino, octafluorocyclobutane yagwiritsidwa ntchito kwambiri m'magawo aukadaulo monga kutchinjiriza kwamphamvu, kuyeretsa ndi kutchinjiriza, komanso chithandizo cha plasma m'zaka zaposachedwa. Kuyankha mwadzidzidzi kutayikira: valani zida zopumira zokha komanso zovala zogwirira ntchito. Dulani gwero la mpweya. Mpweya wopuma ndi convection, dilution ndi diffusion. Sungani chidebe chotayikira pamalo otseguka ndikuyang'anira mpweya wopuma. Zidebe zotayikira sizingagwiritsidwenso ntchito, ndipo muyenera kuchitidwa chithandizo chaukadaulo kuti muchotse mpweya wotsala.

Ntchito:

Makampani Ogulitsa Chakudya:

imagwiritsidwa ntchito makamaka ngati mankhwala opopera mumakampani azakudya, komanso ngati choziziritsira.

② Makampani a Zamagetsi:

Chosangalatsa kwambiri pa ma circuit ophatikizidwa, chimagwiritsidwanso ntchito ngati kusakaniza kwa dielectric ndi sf6, komanso chothandizira polymerization pakupanga fluorinated compound.

Phukusi lachizolowezi:

Ubwino:

①Zaka zoposa khumi pamsika;

②Wopanga satifiketi ya ISO;

③Kutumiza mwachangu;

④Magwero okhazikika a zinthu zopangira;

⑤Njira yowunikira pa intaneti yowongolera khalidwe pa sitepe iliyonse;

⑥Kufunika kwakukulu komanso njira yosamala yogwiritsira ntchito silinda musanadzaze;
