I roto i te tirohanga whānui o te hanga ahumahi, kei reira tonu ētahi wāhanga iti e mahi puku ana i ngā mahi nui. Ko te pūwero whakakorenga hauota silicon carbide he "toa kei muri i ngā whakaaturanga" - e huna ana i roto i te pourewa whakakorenga hauota o ngā tipu hiko me ngā tipu maitai, i ia rā i ia rā e "horoi" ana i te hau paru ahumahi, e aukati ana i te hauhā whanariki kino i mua i te tukunga. He aha te āhuatanga motuhake o tēnei taputapu tika i hangaia ki te rauemi silicon carbide?
1, He aha te take i whakamahia ai te silicon carbide? Ko ngā 'wheua mārō' o te rauemi
Kia mārama ai ki ngā painga ongā pūwero whakakorenga whanariki silicon carbide, me tīmata tātou ki tō rātou "hanganga". He rauemi kore-waro hangai te silicon carbide, me ngā ngota e herea ana e ngā hononga covalent tino kaha hei hanga i tētahi hanganga pumau e rite ana ki te taimana. E toru ngā "mana nui" o tēnei hanganga:
Ātete ki te waikura: Ka konatunatua te hau para ahumahi ki ngā matū waikura pēnei i te kohu waikawa me te paru kōhatu, ā, ka waikura wawetia, ka kī tonu hoki ngā pūwero whakarewa noa. He nui ake te ātete o te silicon carbide ki te waikawa me te kawakore i ngā konganuku, ā, ka taea te pupuri i te hanganga pai ahakoa te roa o te rumaki ki roto i ngā taiao waikura nui.
Ka taea te tu atu i ngā pāmahana teitei: Ka eke te pāmahana hau para i roto i te pourewa whakakore whanariki ki ngā rau nekehanga Celsius, ā, i ētahi wā ka nui ngā rerekētanga pāmahana nā te tīmatanga me te whakaweto o ngā taputapu. He tino kaha te pumau o te wera o te silicon carbide, ā, kāore e ngawari ki te pakaru ahakoa te pānga ohorere o te pāmahana teitei. He pono tonu i raro i ngā āhuatanga pāmahana tino teitei.
Ka taea te tu atu i te pakaru me te haehae: Ina haere te paru desulfurization tere-tere i roto i te pūwero, ka pakaru tonu te pakitara o roto. Ko te pakeke o te silicon carbide te tuarua o te taimana, ā, ka taea e ia te ātete ngāwari ki tēnei momo pakaru. Ko tōna roa mahi he maha ngā wā i te roa o te ora o ngā pūwero kirihou, whakarewa rānei noa.
2, Ehara i te mea he 'pakeke' anake, engari he 'whakatairanga' hoki mō te whai huatanga o te whakakorenga whanariki
He nui atu te uara o ngā pūwero whakakore pūwero silicon carbide i te "roa o te ora". He mea ngaro kei roto i tōna hoahoa: mā ngā awa porowhita o roto ka taea e te paru whakakore pūwero te whakaranu tonu me te tukinga i roto i te rere, ā, ka huri hei pata iti, kia ōrite hoki – ko te nui ake o te horahanga pā i waenga i ēnei pata me te hau paru, ko te teitei ake o te whai huatanga o te mimiti hauhā whanariki.
He mea nui ake, kāore e ngāwari te ārai. Ka konatunatua ngā matūriki iti ki roto i ngā paru ahumahi, ā, ka ngāwari te ārai i ngā awa whaiti o ngā pūwero noa, ka hua ake he rehu kore taurite, ā, ka heke te pai o te tango whanariki. He whānui te hoahoa awa rere o te pūwero silicon carbide, e āhei ai ngā matūriki ki te haere mārire, ka whakaiti i te wā kore mahi me te tiaki i puta mai i te ārai.
3、 Te 'kōwhiringa nui' i raro i ngā kaupapa here tiaki taiao
I te mea kua tino kaha haere ngā paerewa taiao, kua piki ake ngā whakaritenga a ngā umanga mō ngā taputapu whakakore pūngao. Hei tauira, kua tino whakawhāitihia te rohe kukū o te hauhā whanariki i roto i te hau paru e tukuna ana e ngā tipu hiko. Ko te tikanga o tēnei me nui ake te whai hua me te pumau o te pūnaha whakakore pūngao – ā, ka pā tika te mahi a te pūwero ki te hua o te purenga whakamutunga.
Ahakoa he nui ake te utu tīmatanga mō ngā pūwero whakakore hauota silicon carbide i ērā o ngā pūwero noa, he nui ake te ōhanga o ēnei i te wā roa. He roa ake tōna ora mahi i ērā o ngā pūwero kirihou, ā, ka taea te whakaiti i te auau o te whakakapinga me te ngaronga o te wā kore mahi. Mō ngā umanga e whai ana i te mahi whakaputa pumau, he mea tino nui te āhuatanga o te "haumi kotahi te wā, kore manukanuka mō te wā roa".
4, Ehara i te mea ko te whakakorenga pūngāwerewere anake, engari e kitea ana ngā tono ā muri ake nei
Haunga te maimoatanga hau para ahumahi, kei te puta ake te pūmanawa o ngā rauemi silicon carbide i roto i ngā mara maha atu. Nā tōna ātete pāmahana teitei me te ātete i te hihi ka tū motuhake i roto i ngā mara teitei pēnei i te pūngao karihi me te rererangi; I roto i te umanga pūngao hou, ka whakamahia hoki i roto i ngā taputapu sintering pāmahana teitei mō ngā rauemi pākahiko lithium. Hei pūwero desulfurization, kei te noho tonu hei wāhanga nui o te whakahaere taiao o nāianei.
Ko tēnei 'wāhanga iti' e huna ana i roto i te pourewa whakakorenga whanariki he piriti i waenganui i te ao ahumahi me te tiaki taiao. Ka whakamahia e ia te mātauranga o te pūtaiao rauemi kia taea ai te hanga ahumahi te noho tahi me te rangi kikorangi me ngā kapua mā – koinei pea te whakamaoritanga pai rawa atu o te hangarau e tiaki ana i te taiao.
