I roto i ngā ahumahi hou, kei te piki haere te uara o ngā rauemi whai hua, pai mō te taiao, me te pakari. Ko ngā uku moroiti silicon carbide, hei rauemi moroiti mahi-teitei, kei te whai wāhi nui ki ngā mara pēnei i te tātari pāmahana-tiketike, te tiaki taiao, me te miihini matū tika nā ō rātou painga mahi ahurei.
1, He aha te uku moroiti silicon carbide?
Karāhe hiraka (SiC)he matū i hangaia mai i te silicon me te waro, he tino pakeke, he ātete ki te pāmahana teitei, he ātete ki te waikura, ā, e mōhiotia ana ko te "taimana ahumahi". Ko ngā uku moroiti he rauemi kua whakakiia ki ngā pore iti i roto, e hoatu ana ki a rātou he āhuatanga tātari, mimiti, me te manawa pai.
Ka whakakotahi ngā uku moroiti-porous o te silicon carbide i ngā āhuatanga pai o te silicon carbide me ngā āhuatanga o te hanganga moroiti-porous, ka taea te pupuri i te pumau i roto i ngā taiao tino kino, me te whakatutuki i te tātari me te wehenga pai o ngā hau, o ngā wai rānei, ka waiho hei taputapu maha-whakamahinga i roto i te mara ahumahi.
2, He aha te take e pai ai ngā uku moroiti kua whakakikoruatia ki te silicon carbide?
1. Ātete ki te pāmahana teitei, pumau pērā i te toka
He maha ngā rauemi ka ngāwari ki te whakarerekē, ki te pakaru rānei i ngā pāmahana teitei, engari ka taea e ngā uku silicon carbide microporous te mahi pumau i roto i ngā taiao neke atu i te 1200 ℃ mō te wā roa, me te kore e pā ki tā rātou mahi nā te pāmahana teitei. Nā tēnei he kōwhiringa pai mō te maimoatanga hau para pāmahana teitei i roto i ngā ahumahi pēnei i te whakarewa me te hiko.
2. Te tātari tika me te wehenga whai hua
Mā te whakahaere tika i te rahi o ngā pūwero iti, ka taea e ngā uku pūwero iti o te silicon carbide te aukati i ngā matūriki iti, tae atu ki ngā matū taumata ngota. I roto i te hanga matū, ka taea e ia te wehewehe i ngā whakakorikori; i roto i te mara o te tiaki taiao, ka taea e ia te hopu i te puehu kino i roto i te hau para ahumahi, ā, ka āwhina i te hanga matomato.
3. He pakari, he whakaiti hoki i ngā utu tiaki
He tino kaha te ātete o te rauemi silicon carbide ki te kakahu me te ātete ki te ru wera. Ahakoa i roto i ngā taiao hurihuri makariri me te wera nui, ka taea e ngā uku silicon carbide microporous te pupuri i te pumau, ka whakaiti i te auau o te whakakapinga taputapu me te whakaiti i ngā utu whakahaere a te umanga.
3, Ngā āhuatanga tono o ngā uku moroiti silicon carbide
Te purenga hau pāmahana teitei: pērā i te whakarewa whakarewa, te tahunga para, me ētahi atu, ka taea te hopu pai i ngā matūriki i roto i te hau paipa pāmahana teitei me te whakaora i te pūngao wera.
Te matū tino tika me te whakaterenga: Hei kawe whakaterenga, ka whakapai ake i te whai huatanga o te tauhohenga, ā, ka taea te tu atu ki ngā taiao uaua pēnei i ngā waikawa me ngā kawakore kaha.
I te mara o te pūngao hou, ka tautokona te tohatoha hau pumau i roto i ngā tukanga pēnei i te whakarite pūngao hauwai me te sintering rauemi pākahiko.
Te maimoatanga wai taiao: Mā te whakarerekētanga o te mata, ka taea te whakamahi mō te maimoatanga wai para hinuhinu, te mimiti konganuku taumaha, me ētahi atu, hei āwhina i te whakaputanga ma.
4, Te ahunga whanaketanga ā muri ake nei
I te whanaketanga o te hangarau ahumahi me te pikinga o te hiahia mō te tiaki taiao, kei te whanake haere ngā uku moroiti silicon carbide ki te taumata tika me te mohio. Hei tauira, mā te whakarei ake i tana mahi mā te hangarau paninga hiato, mā te whakakotahi rānei me ngā pūnaha aroturuki mohio hei whakatutuki i te mana whakahaere wā-tūturu. I te heke mai, e tika ana kia tiaho i roto i ngā mara teitei pēnei i ngā semiconductors me te biomedicine.
whakatau
Ahakoa te āhua noa o ngā uku silicon carbide microporous, he mea nui tonu tā rātou mahi i roto i te hanga ahumahi me te tiaki taiao. Ka tiakina pukutia te ma me te whai huatanga o te hanga ahumahi me te mahi pumau, te kaha tātari pai, me te roa o te mau. I te heke mai, me te auahatanga tonu o te hangarau, ka whai wāhi tonu ki te whakapai ake i te ahumahi me te whanaketanga matomato.
