Te Whakamāramatanga me ngā Paerewa Parakore o te Parakore-TeiteiMetana

Teitei-parakoremetanae pā ana ki te hau methane he tino parakore. I te nuinga o te wā, ko te methane he 99.99% te parakore, neke atu rānei, ka taea te kī he tino parakore.metanaI roto i ētahi tono tino pakari, pērā i te umanga hikohiko, ka eke pea ngā whakaritenga parakore ki te 99.999%, ki runga ake rānei. Ka tutukihia tēnei parakore teitei mā roto i ngā hangarau whakamaemae me te wehewehe hau matatini hei tango i ngā poke pērā i te makuku, te hauhā waro, te hauhā monoki, te hauwai, me ētahi atu wāhanga hau.

Ngā wāhi tono o te methane parakore teitei

I roto i te umanga hikohiko,methane parakore teiteie whakamahia ana hei hau whakairo me te rauemi mata mō te whakatakoto kohu matū (CVD) i roto i te hanga haurua-ā-ira. Hei tauira, i roto i te whakairo plasma, ka konatunatua te methane ki ētahi atu hau hei whakairo tika i ngā rauemi haurua-ā-ira, ka hanga he tauira porowhita iti. I roto i te CVD,metanae whakarato ana i te puna waro mō te whakatipu i ngā kiriata angiangi kei runga i te waro, pērā i ngā kiriata silicon carbide, e whai wāhi nui ana ki te whakapai ake i te mahi me te pumau o ngā taputapu haurua-ira.

Ngā Rauemi Matū Mata:Methane tino parakoreHe rauemi mata nui te chloromethane mō te hanga i ngā matū maha he nui te uara tāpiri. Hei tauira, ka taea e ia te tauhohe ki te chlorine hei whakaputa i ngā matū chloromethane pērā i te chloroform, te dichloromethane, te trichloromethane, me te carbon tetrachloride. He rauemi mata te chloromethane mō te hanga i ngā matū organosilicon, he mea whakamahi noa te dichloromethane me te trichloromethane hei whakarewa, ā, i whakamahia te carbon tetrachloride i mua hei tinei ahi, engari kua tino herea tōna whakamahinga inaianei nā ōna pānga whakangaro ozone. Hei tāpiri,metanaka taea te huri hei syngas (he ranunga o te hauota waro me te hauwai) mā te whakahounga, ā, he rauemi mata nui te syngas mō te hanga methanol, te haukini hangai, me te maha atu o ngā hua matū.

I roto i te rāngai pūngao: Ahakoa ko te methane noa (hau māori) te rauemi pūngao matua,methane parakore teiteiHe mahi anō hoki tāna i roto i ētahi tono pūngao motuhake. Hei tauira, i roto i ngā pūtau wahie, ka taea te whakamahi i te methane tino parakore hei wahie, ka whakahoutia hei whakaputa hauwai, e whakakaha ana i te pūtau wahie. Ki te whakatauritea ki ngā wahie pūmua tuku iho, ka nui ake te whai huatanga o te pūngao o ngā pūtau wahie e whakamahi ana i te methane tino parakore, ā, ka iti ake hoki ngā tukunga parahanga.

Te whakarite i ngā hau paerewa:Methane tino parakoreka taea te whakamahi hei hau paerewa mō te whakatikatika i ngā taputapu tātari hau. Hei tauira, i roto i te chromatograph hau, mā te whakamahimethane parakore teiteiKa taea e te hau paerewa e mōhiotia ana te kukū te whakatikatika i te aro me te tika o te taputapu ki te kimi, kia tika ai, kia pono ai hoki ngā hua tātari mō ētahi atu hau.
