Octafluorocyclobutane (C4F8)

Nā ʻāpana ʻenehana

Octafluorocyclobutanehe mea kemika, he mea hoʻoheheʻe perfluorinated o ka cyclobutane, a ʻo C4F8 kona kumu hoʻohālike. ʻAʻohe kala, ʻaʻala ʻole, kinoea hiki ʻole ke hoʻā. Paʻa ma ke ʻano a ʻaʻole ʻona. Inā nui ka wela, e piʻi aʻe ke kaomi o loko o ka pahu, a aia ka pilikia o ka pohā a me ka pahū. ʻO ka huahana hoʻopau (decomposition) he hydrogen fluoride. He kūpaʻa loa ka Octafluorocyclobutane a ʻaʻole e hoʻopili me nā mea ʻē aʻe ma lalo o nā kūlana maʻamau. Hiki ke hana ʻia ka pahu hoʻopaʻa a me ka hoʻokō ʻana i ka hao hao a me ke kila kila ma 120 ° C, a hiki ke hoʻohana ʻia ke kila ma 175 ° C. Ke ʻoi aku ka nui o 400 ° C, hiki ke hōʻino iki ʻia nā mea Inconel e like me, nickel a me platinum. Ma 500 ° C, he hopena catalytic kēia mau mea i ka decomposition. Ma nā wela kiʻekiʻe (600 ° C), hiki i ka octafluorocyclobutane ke hoʻoheheʻe i ke kalapona, carbon tetrafluoride a me nā mea ʻawaʻawa. Loaʻa i ka Octafluorocyclobutane kahi ākea ākea o nā noi. I nā makahiki i hala iho nei, ua hoʻohana nui ʻia ia ma ke ʻano he refrigerant e pani i nā pūhui chlorofluorocarbon i pāpā ʻia. Eia kekahi, hoʻohana maʻamau ia i ka media insulating gas, solvents, sprays, foaming agents, a me nā etchants kaapuni nui. , Heat pump wai hana a me nā mea maka no ka hanaʻana i nā monomers C2F4 a me C3F6. Hoʻohana ʻia ka octafluorocyclobutane maʻemaʻe kiʻekiʻe (ma luna o 5N) ma ke ʻano he etching agent a me ka mea hoʻomaʻemaʻe no nā kaapuni VLSI. Ma muli o kāna mau waiwai paʻa, non-toxicity, zero ozone depletion potential (ODP), a me ka insulation maikaʻi, ua hoʻohana nui ʻia ka octafluorocyclobutane i nā ʻenehana loea e like me ka insulation high-voltage, ka hoʻomaʻemaʻe a me ka etching, a me ka mālama plasma i nā makahiki i hala. Pane ulia pōpilikia i ka leakage: e ʻaʻahu i nā mea hanu a me nā lole hana. E ʻoki i ke kumu kinoea. ʻO ka ventila a me ka convection, ka dilution a me ka diffusion. E hoʻoneʻe i ka pahu hū i kahi ākea a e nānā pono i ka ea. ʻAʻole hiki ke hoʻohana hou ʻia nā ipu ʻōpala, a pono e hoʻomaʻamaʻa ʻenehana e wehe i ke koena kinoea.

Noi:

① ʻOihana Meaʻai:

Hoʻohana nui ʻia ia e like me ka spraying agent i ka ʻoihana meaʻai, refrigerant.

② ʻOihana uila:

enchant no ke kaapuni hoʻohui, ua hoʻohana pū ʻia e like me ka hui dielectric me sf6, a me ke kōkua polymerization no ka hui fluorinated.

Pūʻolo maʻamau:

Pōmaikaʻi:

①Ma mua o ʻumi makahiki ma ka mākeke;

②Ka mea hana palapala ISO;

③Hoʻouna wikiwiki;

④Stable kumu kumu waiwai;

⑤ ʻO ka ʻōnaehana hoʻopaʻa inoa pūnaewele no ka hoʻokele maikaʻi ʻana i kēlā me kēia pae;

⑥Ke koi kiʻekiʻe a me ke kaʻina hana no ka mālama ʻana i ka cylinder ma mua o ka hoʻopiha ʻana;
