He tino parakore te karāhe motuhake, he tino matotoru, he kaha hokikarāpetiHe rauemi tēnei, ā, he tino ātete ki te waikura, he pumau ki te pāmahana teitei, ā, he pai hoki te kawe hiko. He mea hanga ki te karāti maori, ki te karāti hangai rānei i muri i te maimoatanga wera pāmahana teitei me te tukatuka pēhanga teitei, ā, he mea whakamahi noa i roto i ngā mahi ahumahi i roto i ngā taiao pāmahana teitei, pēhanga teitei me te waikura.
Ka taea te wehewehe ki ngā momo rerekē tae atu ki te isostaticporaka karāhe, poraka karāhe kua whakaputahia, kua whakarewahiaporaka karāheā, i wiriporaka karāhe.
Ngā Hangarau Hanga:
KarāpitiHe huānga ahurei kore-whakarewa te mea nei, he mea hanga mai i ngā ngota waro kua whakaritea ki roto i te hanganga whatu hexagonal. He rauemi ngohengohe, pakarukaru hoki e whakamahia whānuitia ana i roto i ngā tono ahumahi maha nā ōna āhuatanga ahurei. Ka taea e te karāpiti te pupuri i tōna kaha me tōna pumau ahakoa ngā pāmahana neke atu i te 3600 °C. Nā, me whakaatu e au te tukanga whakaputa o te karāpiti motuhake.
Karāhe isostatic, he mea hanga ki te karāpiti parakore teitei mā te pēhi, he rauemi kore e taea te whakakapi e whakamahia ana i roto i te hanga oumu karaihe kotahi, ngā tioata karāpiti whakarewa tonu, me ngā irahiko karāpiti mō te miihini tuku hiko. Haunga ēnei tono matua, he whānuitia te whakamahinga i roto i ngā mara o ngā koranu mārō (ngā whakamahana oumu korehau, ngā pereti sintering, me ētahi atu), te keri (te hanga pokepokea ai), te ahumahi matū (ngā whakawhiti wera, ngā wāhanga ātete-waikura), te whakarewa (ngā oko para), me te mīhini (ngā hiri mīhini).
Hangarau Whakairo
Ko te mātāpono o te hangarau pēhi isostatic e ahu mai ana i te ture a Pascal. Ka hurihia te pēhi kotahi-ahunga (rua-ahunga rānei) o te rauemi ki te pēhi maha-ahunga (ahunga-katoa). I roto i te tukanga, kei roto tonu ngā matūriki waro i te āhua koretake, ā, he ōrite te matotoru o te rōrahi me ngā āhuatanga isotropic. Haunga tēnā, kāore e pāngia e te teitei o te hua, nō reira kāore he rerekētanga mahi, he iti rānei te rerekētanga mahi o te karāhe isostatic.
E ai ki te pāmahana e puta ai te hanganga me te whakapakeketanga, ka taea te wehewehe i te hangarau pēhi isostatic ki te pēhi isostatic matao, te pēhi isostatic mahana, me te pēhi isostatic wera. He nui te mātotoru o ngā hua pēhi isostatic, ko te tikanga he 5% ki te 15% teitei ake i ērā o ngā hua pēhi pokepokea kotahi-aronga, e rua-aronga rānei. Ka taea e te mātotoru whanaunga o ngā hua pēhi isostatic te eke ki te 99.8% ki te 99.09%.
He tino pai ngā mahi a te karāpeti whakarewa i roto i te kaha ā-pūkaha, te ātete ki te pakū, te mātotoru, te pakeke me te kawe hiko, ā, ka taea te whakapai ake i ēnei mahi mā te whakakī i te kapia, i te konganuku rānei.
He pai te kawe hiko o te karāpeti whakarewa, he ātete ki te pāmahana teitei, he ātete ki te waikura, he parakore teitei, he whakahinuhinu-ā-ia anō, he ātete ki ngā ru wera me te ngāwari ki te miihini tika, ā, he whānuitia te whakamahinga i roto i ngā mara o te whakarewanga tonu, te whakarewa koranu mārō me te mate hiko, te mura hiko, te hiri miihini, me ētahi atu.
Hangarau Whakairo
Ko te tikanga whakapūkara e whakamahia whānuitia ana hei whakaputa i ngā hua iti kua pēhia matao, i ngā hua rānei kua āta hangaia. Ko te kaupapa matua he whakakī i tētahi nui o te whakapiri ki roto i tētahi pokepoke o te āhua me te rahi e hiahiatia ana, kātahi ka pēhia mai i runga, i raro rānei. I ētahi wā, ka pēhia mai i ngā taha e rua hei pēhi i te whakapiri kia āhua i roto i te pokepoke. Kātahi ka wetekina te hua kua pēhia, ka whakamatao, ka tirotirohia, ka whakatakotoria.
E rua ngā mīhini whakahāngai poutū me ngā mīhini whakahāngai whakapae. Ko te tikanga whakahāngai ka taea anake te pēhi i te hua kotahi i te wā kotahi, nō reira he iti noa te pai o te whakaputa. Heoi, ka taea e ia te whakaputa hua tino tika e kore e taea te hanga e ētahi atu hangarau. Heoi anō, ka taea te whakapai ake i te pai o te whakaputa mā te pēhi i ngā whakahāngai maha i te wā kotahi me ngā raina whakaputa aunoa.
Ka hangaia te karāpiti i whakapūtāhia mā te whakaranu i ngā matūriki karāpiti tino parakore me te mea here, kātahi ka whakapūtāhia ki roto i te mea whakapūtā. Ki te whakatauritea ki te karāpiti isostatic, he rahi ake te rahi o te kōpura o te karāpiti i whakapūtāhia, ā, he iti ake te kaha, engari he nui ake te kawe wera me te hiko.
I tēnei wā, ko te nuinga o ngā hua waro me te karāpeti e hangaia ana mā te tikanga whakaputa. Ko te nuinga o ēnei e whakamahia ana hei wāhanga whakamahana me ngā wāhanga kawe wera i roto i ngā tukanga maimoatanga wera pāmahana teitei. Hei tāpiri, ka taea hoki te whakamahi i ngā poraka karāpeti hei irahiko hei kawe i te whakawhiti iahiko i roto i ngā tukanga hiko. Nō reira, e whakamahia whānuitia ana hei hiri miihini, hei rauemi kawe wera me ngā rauemi irahiko i roto i ngā taiao tino kino pēnei i te pāmahana teitei, te pēhanga teitei, me te tere teitei.
Hangarau Whakairo
Ko te tikanga whakaputa ko te utaina o te whakapiri ki roto i te rango whakapiri o te mīhini perehi ka whakaputa. Kei mua i te mīhini perehi he mowhiti whakaputa ka taea te whakakapi (ka taea te whakakapi hei whakarerekē i te āhua me te rahi o te hua), ā, kei mua i te mowhiti whakaputa he ārai neke. Kei muri i te rango whakapiri te pūwero matua o te mīhini perehi.
I mua i te pēhanga, whakatakotoria he ārai i mua i te mowhiti whakaputa, ka pēhia mai i te taha ke hei pēhi i te whakapiri. Ina tangohia te ārai, ā, ka pēhia tonutia, ka puta te whakapiri mai i te mowhiti whakaputa. Tapahia te rīpene whakaputa ki te roa e hiahiatia ana, whakamataohia, ka tirotirohia i mua i te whakarārangi. Ko te tikanga whakaputa he tukanga whakaputa haurua-tonu, ko te tikanga i muri i te tāpiri i tētahi nui o te whakapiri, ka taea te whakaputa tonu i ētahi hua (ngā poraka karāpiti, ngā rauemi karāpiti).
I tēnei wā, ko te nuinga o ngā hua waro me te karāpeti e whakaputaina ana mā te tikanga extrusion.
He hanganga ōrite te karāpeti wiri, he rahi waenga te rahi o te kōpura. Haunga tēnā, ka tino rongonui nā te iti o te pungarehu, te kaha miihini kua whakarei ake, me te pumau hiko me te wera pai, ā, he whānuitia te whakamahinga mō te tukatuka i ngā wāhanga mahi nui. Ka taea hoki te whakapakari ake i muri i te whakakī i te kapia, i te maimoatanga ārai-waikura rānei.
He whānuitia te whakamahinga hei huānga whakamahana me te whakamarumaru i roto i te hanga oumu polysilicon me te monocrystalline silicon i roto i te umanga photovoltaic. He whānuitia hoki te whakamahinga i roto i te hanga potae whakamahana, ngā wāhanga whakawhiti wera, te whakarewa me te whakarewa i ngā ipu whakarewa, te hanga i ngā pūnga n e whakamahia ana i roto i ngā tukanga hiko, me te hanga ipu whakarewa mō te whakarewa me te whakakotahi.
Hangarau Whakairo
Ko te kaupapa o te hanga i te karāpeti wiri ko te whakakī i te pokepokea ai ki te ranunga rite ki te whakapiri, kātahi ka whakatakotoria he pereti whakarewa taumaha ki runga. I te taahiraa e whai ake nei, ka whakakīia te rauemi mā te wiri i te pokepokea ai. Ki te whakatauritea ki te karāpeti whakaputa, he nui ake te isotropy o te karāpeti i hangaia e te wiri. Ka hangaia ngā hua karāpeti mā te tikanga whakaputa.
