Octafluorocyclobutane (C4F8)

Magadzirirwo ehunyanzvi

Octafluorocyclobutane chinhu chemakemikari, chinobva mu cyclobutane ine perfluorine, uye fomura yayo yemakemikari iC4F8. Gasi risina ruvara, harinhuwi, haribati. Rakagadzikana uye harina chepfu. Kana paine kupisa kwakanyanya, kumanikidzwa kwemukati memudziyo kuchawedzera, uye pachava nenjodzi yekutsemuka nekuputika. Chigadzirwa chekutsva (kuora) ihydrogen fluoride. Octafluorocyclobutane yakasimba uye haibati nezvimwe zvinhu mumamiriro ezvinhu akajairwa. Mudziyo wekuchengetera uye wekuita unogona kugadzirwa nesimbi yakakandwa nesimbi isingatsvi pa120°C, uye simbi inogona kushandiswa pa175°C. Kana ikapfuura 400°C, Zvinhu zveInconel zvakaita se, nickel neplatinum zvinogonawo kukuvara zvishoma. Pa500°C, zvinhu izvi zvine simba rekukonzera kuora. Pakupisa kwakanyanya (600°C), octafluorocyclobutane inogona kuora kuita kabhoni, kabhoni tetrafluoride uye mishonga ine chepfu. Octafluorocyclobutane ine mashandisirwo akasiyana-siyana. Mumakore achangopfuura, yave ichishandiswa zvakanyanya semuchina wekuchengetera mvura kuti itsive ma chlorofluorocarbon compounds akarambidzwa. Pamusoro pezvo, inowanzoshandiswawo mu gas insulating media, solvents, sprays, furo agents, uye large-scale circuit etchants. , Heat pomp working fluid uye raw materials ekugadzira C2F4 neC3F6 monomers. High-purity octafluorocyclobutane (pamusoro pe5N) inoshandiswa se etching agent uye cleansing agent yeVLSI circuits. Nekuda kwehunhu hwayo hwakagadzikana, non-toxicity, zero ozone depletion potential (ODP), uye insulation yakanaka, octafluorocyclobutane yave ichishandiswa zvakanyanya muminda yehunyanzvi senge high-voltage insulation, kuchenesa ne etching, uye plasma treatment mumakore achangopfuura. Emergency response kana leak: pfeka self-contained breath apparatus uye work clothes. Cheka gasi rinobuda. Ventilation ne convection, dilution uye diffusion. Fambisa mudziyo unobuda mvura kunzvimbo yakashama uye teerera kufefetera. Magaba anobuda mvura haachagoni kushandiswa, uye anofanira kurapwa nehunyanzvi kubvisa gasi rasara.

Kushandiswa:

① Indasitiri yezvekudya:

inonyanya kushandiswa semushonga wekupfapfaidza muindasitiri yechikafu, uye semuchina wekuisa mufiriji.

② Indasitiri yeMagetsi:

Inobatsira pakubatanidza ma "integrated circuit", yaishandiswawo semusanganiswa we dielectric ne sf6, uye serubatsiro rwe polymerization kune fluorinated compound.

Pakeji yakajairika:

Zvakanakira:

①Makore anopfuura gumi ari pamusika;

②Mugadziri wezvitupa zveISO;

③Kutumira nekukurumidza;

④Manyuko ezvinhu zvakabikwa akagadzikana;

⑤Sisitimu yekuongorora yepamhepo yekudzora mhando padanho rega rega;

⑥Kushandiswa kwakawanda uye kwakanyatsorongwa kwekubata silinda usati wazadza;
