Te Tūranga o te Coke Hinu Whakapūkara i roto i ngā Ahumahi Whakarewa o te Silicon Ahumahi me te Silicon Carbide
I. Te Tūranga i roto i te Whakarewa Hiraka Ahumahi
1. Mahi Whakaiti Matua
Ko te kōka hinu kua whakakāwhatia tētahi o ngā matū whakaiti waro matua i roto i te hanga silicon ahumahi. Nā te nui o te waro (90%-97%) me ōna āhuatanga pungarehu iti, he rauemi mata nui tēnei hei whakarato i te waro e hiahiatia ana mō ngā tauhohenga. I te wā e whakarewahia ana te oumu pewa hiko, ka āwhina te kōka hinu ki te huri i te silica (SiO₂) ki te silicon ahumahi mā roto i ngā tauhohenga whakaiti waro. Hei tāpiri, ka āwhina tōna kawe hiko ki te whakahaere i te ātete o te utu oumu, te whakahaere i te hohonutanga o te whakaurunga hiko me te arotau i te mahi o te oumu pewa hiko.
2. Te Arotau i te Mahi o te Utu o te Oumu
- Te Whakatikatika Ātete: Ka pā te kawe hiko o te kōka hinu ki te ātete o te utu oumu. Mā te whakarerekē i tōna horopeta me te rahi o te matūriki, ka taea te whakapai ake i te whai huatanga wera o te oumu pewa hiko, ka whakaiti i te whakapaunga hiko.
- Whakapai Ake i te Āheinga: Ka memeha haere te kōka hinu parakore i ngā pāmahana tiketike, ka puta he kirinuku ki runga i te mata o te oumu. Hei whakaiti i tēnei, ka whakaranua ngā maramara rakau, ngā wahie rānei hei whakanui ake i te ātete motuhake, hei whakarei ake i te āheinga o te oumu, hei whakau hoki i ngā āhuatanga mahi.
- Tāpiritanga Mahi Matū: He ngoikore ngā āhuatanga whakaiti o te kōka hinu, ā, he maha ngā wā ka whakamahia ngātahitia me te waro silicon iti-pungarehu, te waro rānei hei whakarite i te haere maeneene o ngā tauhohenga whakaiti.
3. Taurite i waenganui i te Kounga me te Utu
- Te Hanganga Silikoni Kounga Teitei: Nā te iti o te pungarehu o te petroleum coke, he pai mō te hanga siliconi ahumahi parakore teitei. Heoi, me whakahaere te whanariki, te vanadium, te nickel, me ētahi atu poke, inā koa i roto i te hanga organosilicon, ina whakawhāitihia ngā ōwehenga o te petroleum coke hei ārai i te paitini whakakorikori.
- Ngā Painga Ōhanga: Ki te whakaritea ki te waro, he whānuitia te wātea o te kōka hinu, he pumau te utu, ā, he iti ake te pānga o ngā kaupapa here taiao, nā reira koia te matū whakaiti pai mō te whakaputanga nui.
II. Te Tūranga i roto i te Whakarewatanga o te Silicon Carbide
1. Te Whakarato Pūtake Waro
Ko te hanga waro silicon carbide (SiC) me whakamahi i tētahi pūtake waro parakore teitei. Whai muri i te whakapūkara, ka whakaatuhia e te kōka hinu kua whakapūkaratia he iti ake te ihirangi pūngāwerewere me te whakanui ake i te whakapūkara, ka whakarato i tētahi pūtake waro pumau e whakatairanga ana i te tauhohenga ā-wāhanga totoka i waenga i te silicon me te waro hei whakaputa i te waro silicon carbide parakore teitei.
2. Ngā Whakamahinga i roto i ngā Rauemi Whakakoi
Ka taea te whakamahi tika i te kōka hinu hei hanga i ngā mea whakakoi karāhe silicon (hei tauira, ngā wira huri, te pepa kirikiri). Nā te pakeke me te ātete ki te pakaru, he mea nui tēnei hei rauemi mata mō te tukatuka whakarewa, te whakakanapa uku, me ētahi atu mahi.
3. Te Arotautanga o te Tukanga
- Maimoatanga Whakapūngā: Mā te whakapūngā i te kōka hinu mata i te 1300°C ka whakaitihia te nui o te hauwai, ka whakarei ake hoki i te whakapūngā, ka whakapai ake i te kawe hiko me te ātete wera o ngā hua silicon carbide.
- Te Whakahaere Rahi o te Matūriki: Mā te whakarerekē i te rahi o te matūriki o te petroleum coke ka arotau i te tukanga whakatioata o te silicon carbide, ka whakarei ake i te ōritetanga o te hua.
III. Te Tūranga Whānui me te Uara o te Ahumahi
1. Te Whakapai Ake i te Pai o te Whakarewa
Mā te kawe hiko me te pumau matū o te kōka hinu kua whakakāwhatia ka whakaiti i te whakapaunga pūngao i roto i ngā oumu pewa hiko, ka whakapoto i ngā huringa whakarewa, ā, ka whakapai ake i te whai huatanga o te whakaputanga. Hei tauira, i roto i te whakaputanga silicon ahumahi, ka taea e te whakaranu kōka hinu tika te whakaiti i te whakapaunga hiko mā te 5%-10%.
2. Te Whakapūmau Kounga
Mā te whakahaere i ngā taumata whanariki, pungarehu, me ngā poke i roto i te petroleum coke ka whakaitihia ngā whakaurunga kore-whakarewa i roto i te silicon ahumahi, ka whakarei ake hoki i te parakore o te silicon carbide, ka tutuki ai ngā hiahia o te hangahanga teitei (hei tauira, te silicon carbide kounga-haurua).
3. Te Whakatairanga i te Whakapai Ahumahi
I te ahu whakamua o te umanga whakarewa ki ngā mahi tauine nui me te atamai, ka tautokona e te parakore teitei me te tioata o te kōka hinu kua whakakākahuria te hanga i ngā whakapiri hiko mahi-teitei me ngā hiko waro nui, e whakatairanga ana i ngā whakahoutanga hangarau puta noa i te rāngai.
