Octafluorocyclobutane (C4F8)

Ngā Tawhā Hangarau

He matū te Octafluorocyclobutane, he matū irahiko o te cyclobutane, ā, ko tōna tauira matū ko C4F8. Kore tae, kore kakara, kore mura. He pumau te āhua, ā, kāore he paitini. Mēnā he wera nui, ka piki ake te pēhanga o roto o te ipu, ā, ka tūpono te pakaru me te pahū. Ko te hua tahunga (pirau) ko te hauwai fluoride. He tino pumau te Octafluorocyclobutane, ā, kāore e tauhohe ki ētahi atu matū i raro i ngā āhuatanga noa. Ka taea te hanga i te ipu rokiroki me te tauhohe ki te rino maka me te maitai kore waikura i te 120°C, ā, ka taea te whakamahi i te maitai i te 175°C. Ina neke atu i te 400°C, ka taea hoki te pakaru paku i ngā Rauemi Inconel pēnei i te nickel me te platinum. I te 500°C, he pānga whakaterenga tō ēnei rauemi ki te pirau. I ngā pāmahana teitei (600°C), ka taea e te octafluorocyclobutane te pirau ki te waro, te waro tetrafluoride me ngā matū paitini. He whānui rawa ngā whakamahinga o te Octafluorocyclobutane. I ngā tau tata nei, kua whānuitia te whakamahinga hei whakamatao hei whakakapi i ngā matū chlorofluorocarbon kua āraia. Hei tāpiri, he mea noa hoki te whakamahinga i roto i ngā pāpāho ārai hau, ngā whakarewa, ngā rehu, ngā kaihoko pahuka, me ngā mea whakairo ara iahiko nui. , Te wai mahi papu wera me ngā rauemi mata mō te hanga i ngā monomer C2F4 me C3F6. Ko te octafluorocyclobutane tino parakore (neke atu i te 5N) e whakamahia ana hei kaihoko whakairo me te kaihoko horoi mō ngā ara iahiko VLSI. Nā ōna āhuatanga pumau, kore-paitini, kore-pūmanawa whakaiti ozone (ODP), me te pai o te whakamarumaru, kua whānuitia te whakamahinga o te octafluorocyclobutane i roto i ngā mara hangarau pēnei i te whakamarumaru ngaohiko teitei, te horoi me te whakairo, me te maimoatanga plasma i ngā tau tata nei. Te urupare ohorere ki te turuturu: mauria he taputapu manawa motuhake me ngā kākahu mahi. Tapahia te pūtake hau. Te hauhautanga me te convection, te waimeha me te horapa. Nekehia te ipu turuturu ki tētahi wāhi tuwhera, ā, kia aro ki te hauhautanga. Kāore e taea te whakamahi i ngā ipu turuturu, me whai maimoatanga hangarau hei tango i te hau e toe ana.

Taupānga:

① Ahumahi Kai:

e whakamahia ana te nuinga hei kaihoko rehu i roto i te umanga kai, te refrigerant.

② Ahumahi Hiko:

He mea whakapaipai mō te ara iahiko whakauru, ā, i whakamahia anō hoki hei ranunga dielectric me te sf6, me te āwhina polymerization mō te matū fluorinated.
