I roto i te maimoatanga hau para ahumahi, he mahi nui tā te pūnaha whakakorenga whanariki, ā, kotahi te wāhanga iti nei te āhua – ko te pūwero, e pā tika ana ki te whai huatanga me te pumau o te pūnaha katoa. I ngā tau tata nei,ngā pūwero whakakore pūhā i hangaia ki te rauemi silicon carbidekua noho hei tino pai ki te umanga. I tēnei rā, me kōrero tātou mō ō rātou āhuatanga ahurei.
He aha te karawiti silicon?
Ko te karawiti silicon (SiC) he matū i hangaia mai i te silicon me te waro, he tino pakari, he ātete pai ki te pāmahana me te waikura. Ko tōna pakeke Mohs he 9.5 te teitei, ko te tuarua anake ki te taimana, ko te tikanga he tino ātete ki te kakahu. I taua wā anō, ka taea e te karawiti silicon te pupuri i te pumau i roto i ngā taiao pāmahana teitei i runga ake i te 1350 ℃, ka hoatu he painga taiao ki a ia i roto i ngā āhuatanga mahi uaua.
He aha i whiriwhiri ai i te silicon carbide hei pūwero whakakore pūhā?
Ka taea te whakaahua i te taiao mahi o ngā pūwero desulfurization he "pakari":
-Te roa o te pānga ki ngā paru waikura waikawa me te kawakore
-Te horoi wai tere-teitei
-Ngā piki me ngā heke nui o te pāmahana
-Tērā pea kei roto ngā matūriki totoka
He ngāwari te waikura me te pakaru o ngā pūwero whakarewa tuku iho, engari kāore ngā pūwero kirihou e ātete ki te wera. Ka whakatikatika tika te pūwero silicon carbide i ēnei ngoikoretanga, ā, ko ōna painga matua ko:
1. Ātete tino kaha ki te waikura
He tino pai te ātete o te karawiti silicon ki ngā mea waikura pēnei i te waikawa, te kawakore, me te tote, ā, he nui atu tōna roanga mahi i tērā o ngā pūwero whakarewa me te kirihou.
2. He ātete kakahu pai rawa atu
Ahakoa he matūriki totoka kei roto i te para, ka taea e te pūwero silicon carbide te pupuri i te mahi rehu pumau mō te wā roa, ā, e kore e ngāwari te huri i te koki rehu nā te kakahu.
3. Te mahi ātete pāmahana teitei
I ngā taiao hau paipa pāmahana teitei, e kore ngā pūwero silicon carbide e whakapēpē, e whakangawari rānei, kia pumau ai te pānga rehu.
4. He pai te kawe wera
Ka āwhina i te pūwero ki te tere whakamarara i te wera me te whakaiti i te kino o te ahotea wera.
Te kaupapa mahi o te pūwero silicon carbide
Ka hurihia e te pūwero whakakorenga whanariki silicon carbide te paru whakakorenga whanariki (te nuinga o te paru uku) hei pata iti, ka pa katoa ki te hau paru, ka meinga ngā matū kawakore i roto i te paru kia tauhohe matū ki te hauhā whanariki i roto i te hau paru, ā, ka tutuki te kaupapa o te whakakorenga whanariki.
Ka pā tika te hoahoa me te rauemi o te pūwero ki te pānga o te atomization:
-Ko te angiangi ake o ngā matūriki atomized, ko te nui ake o te horahanga whakapā, ā, ko te teitei ake o te whai huatanga o te desulfurization
-Mā te rauemi silicon carbide ka pumau te pūngao o te pūwero mō te wā roa, ka kore ai e heke te pānga atomization nā te kakahu me te haehae
Ngā horopaki tono
E whakamahia whānuitia ana ngā pūwero whakakorenga haukini karawiti i roto i:
-Te tipu hiko wera
-Te wheketere maitai
-Te whare tahu para
-Ētahi atu rāngai ahumahi e hiahia ana kia whakakorea te hau paru
Ngā whakaaro tiaki o ia rā
Ahakoa he pakari te mau o ngā pūwero silicon carbide, he mea nui tonu te tirotiro me te tiaki auau:
-Tirohia i ia wā mēnā kua purua, kua pakaru rānei te pūwero
-Kia mau tonu te mahi pai o te pūnaha tātari paru
-Whakakapia tonutia te pūwero ina kitea te hekenga o te mahi
whakarāpopototanga
Ahakoa he wāhanga iti noa iho te pūwero whakakorenga hauota silicon carbide i roto i te pūnaha whakakorenga hauota, he mea nui tana mahi ki te whakapai ake i te pai o te whakakorenga hauota me te whakaiti i ngā utu whakahaere. Kua noho hei whiringa pai mō te maha atu o ngā umanga nā te mea he pai te ātete ki te waikura, te ātete ki te kakahu, me te ātete ki te pāmahana teitei.
Mā te whiriwhiri i te rauemi me te hoahoa o te pūwero e tika ana, ehara i te mea ka taea anake te whakapai ake i ngā tohu taiao, engari ka puta hoki ngā painga ōhanga mō te wā roa ki te umanga. I roto i ngā whakaritenga taiao e tino kaha haere ana i ēnei rā, kei te tiaki puku ngā pūwero whakakorenga haukini i tō tātou rangi kikorangi.
