1. Mai i te tekau tau atu i 1960---1963, i hangaia e te kaipūtaiao Amerikana a Schwartzwalder te tikanga whakakī pahuka waro. I whiwhihia ngā uku pore mā te whakakī i te paru uku ki te anga pahuka waro me te tango i ngā mea waro i te pāmahana teitei, kia whakatakotoria ai te kaupapa matua o te whakarite uku pahuka (kei roto ko te turanga alumina), koinei te pūtake hangarau o ngā maramara uku pahuka alumina.
2. Mai i te tekau tau atu i 1970---1978, i whakawhanakehia e Mollard FR me Davidson N o te Hononga o Amerikatātari pahuka uku aluminaka taea te whakamahi mō te tātari whakarewa koranu konumohe mā te whakamahi i te tikanga whakakī pahuka waro me te alumina me te kaolin hei rauemi mata matua, ka tino whakapai ake i te kounga o ngā whakarewanga me te whakaiti i te tere para, e tohu ana kua uru mana ngā maramara uku pahuka konumohe waikura ki te wāhanga tono ahumahi me te whakatairanga i tō rātou whanaketanga nui.
3. I ngā tau 1980---I whakataetae a Ūropi, te Hononga o Amerika, a Hapani me ētahi atu whenua ki te rangahau me te whakawhanake hei hanga i ngā tātari uku pahuka o ngā momo rauemi me ngā whakaritenga. I whakatairangahia te whakaputanga ki te miihini me te aunoatanga, ā, i whakarārangihia ngā hua me te paerewa.
I tīmata a Haina i te rangahau i ngā uku pahuka alumina i te tīmatanga o te tekau tau atu i 1980. Ko te Whare Wānanga Hangarau o Harbin, ko te Whare Wānanga Hangarau Hanga Mīhini o Shanghai me ētahi atu whare wānanga i ārahi i te mahi e tika ana, me te āta whakatinana i te mana motuhake hangarau me te ahumahi, me te whakawhāiti i te āputa ki te mākete o te ao.
Ko te tukanga matua ko te whakakī i te pahuka waro, ā, ko ngā mahi e whai ake nei:
1. Te whakarite i te paru:Whakaranua te paura alumina, te here, te kaiwhakamarara, te āwhina sintering me te wai, ka whakaohokia kia puta he parai ōrite, he nui te ihirangi totoka, he iti te matotoru.
2. Te whakakī me te whakairi paru:Rukuhia te anga pahuka waro kua oti te hanga (pērā i te hautai polyurethane) ki roto i te paru, ka meinga te paru kia piri ki te pakitara kōhao o te anga pahuka kia ōrite mā te whakaputa me te hurihuri hei tango i te paru taikaha.
3. Te whakamaroke me te whakamaroke:Whakatakotoria te tinana pahuka i muri i te paninga ki roto i te oumu whakamaroke, ka whakamaroke ki te 80 – 120 ℃ hei whakapakeke i te piripiri, hei whakapai ake i te kaha o te tinana, hei ārai hoki i te hurihanga o te āhua i te maimoatanga e whai ake nei.
4. Te tango hinu me te tukunga o te kāpia:Tāpirihia te tinana matomato maroke ki roto i te oumu whakawera, ka whakamahana ki te 400 – 600 ℃ kia pirau rawa te anga pahuka waro me te mea here, kia memeha hoki, kia hanga he tinana matomato alumina porous. I tēnei wā, me whakahaere te tere whakamahana kia kore ai e pakaru te tinana matomato.
5. Te whakawera pāmahana teitei:Ka whakamahanahia te tinana matomato kua tangohia te hinu ki te 1400 – 1600 ℃ hei whakahinuhinu, kia pāngia ai ngā matūriki konumohe waikura e te tauhohenga totoka, kia tupu ake ai ngā kakano, kia piri tahi ai, kia hanga he anga uku kaha-teitei, ā, hei whakamutunga ka puta he maramara uku pahuka konumohe waikura.
6.Tukatuka i muri i te tukatuka:Tapahia, whakakanapahia, me te horoi kia rite ki ngā whakaritenga hei whakaputa hua kua oti me ngā rahi me te tika kua tohua.
1. Te kaha o te waikura:Ko te whānui o te pore kei waenga i te 60% me te 90%, ā, ka taea te whakarite i te rahi o ngā pore (mai i ngā tekau maikiromita ki te torutoru mirimita), me ngā pore e hono tahi ana.
2. Te iti o te mātotoru:Ko te mātotoru papatipu he 0.3-1.2 karamu/cm³ anake, he iti iho i tērā o ngā uku alumina matotoru (tata ki te 3.95 karamu/cm³).
3. Ātete pāmahana teitei:Ka taea e te pāmahana whakamahi roa te eke ki te 1200-1600 ℃, engari i te wā poto ka taea te tu atu i te pāmahana teitei o te 1800 ℃, me te kore e rewa, e ngohengohe rānei.
4. Ātete ki te waikura:ātete waikawa me te kawakore (haunga ngā pāpāho kawakore kaha), ātete whakarewa matū, pai ake i ngā rauemi porous whakarewa.
5. He pai te mahi tātari:Ka taea e te hanganga pūwero hono te aukati i ngā matūriki totoka i roto i te wai me te ātete iti ki te wai.
6. Te whakamarumaru wera:Ka ārai te porosity teitei i te kawe wera me te whakawhiti wera, ka waiho hei rauemi whakamarumaru pāmahana teitei tino pai.
7. Kaha ā-mīhini āhua:Ko te kaha pēhanga me te kaha piko e tutuki ana i ngā whakaritenga o te whakamahinga ahumahi, ā, he uaua anō hoki, kāore e ngawari te pakarukaru.
8. Te kaha ki te whakarite:Ka taea te whakarite i ngā rahi, ngā āhua me ngā PPI rerekē, kia taea ai te whakatutuki i ngā hiahia o ngā tono rerekē.
- Mara tātari pāmahana teitei
1. Tātari whakarewa rewa:Ina maka ana ngā konganuku kore-ferrous pērā i te konumohe, te parahi, te konutea, me ētahi atu, ka tātarihia e ia ngā mea whakauru waikura me ngā matūriki poke i roto i te whakarewa hei whakapai ake i te parakore o te makanga.
2. Tātari hau paipa pāmahana teitei:e whakamahia ana mō te tango puehu hau para i te pāmahana tiketike i roto i ngā ahumahi pēnei i te whakarewa, te miihini matū, me te tahunga para, te hopu i ngā matūriki puehu me te pure i ngā hau.
- Mara whakamahana wera
1. Arai oumu ahumahi:paparanga whakamarumaru mō ngā oumu uku, ngā oumu whakarewa, me ngā oumu karāhe hei whakaiti i te ngaronga wera me te penapena pūngao.
2. Ngā wāhanga o te rererangi:Hei rauemi whakamarumaru mō ngā waka rererangi me ngā miihini, ka taea e rātou te tu atu ki ngā taiao pāmahana tiketike.
- Mara kawe whakaterenga
1. Te maimoatanga hauātanga o te motuka:Ka taea te utaina ki ngā whakakōkī hei whakakapi i ētahi kawe whakarewa, e whakamahia ana mō te hurihanga whakakōkī o ngā matū kino i roto i te hau whakaputa.
2. Te whakaterenga matū:Hei kawe i ngā whakakorikori i roto i ngā tauhohenga matū, ka whakanuia e ia te horahanga pa o te tauhohenga, ā, ka whakapai ake i te pai o te whakakorikori.
- Ngā mara kē atu
1. Te mimiti oro me te whakaiti haruru:Whakamahia hei rauemi mimiti harore i roto i ngā taiao pāmahana teitei me te waikura, pērā i ngā wāhanga miihini me ngā paparanga whakamarumaru harore i roto i ngā tipu ahumahi.
2. Rongoā koiora:Ka taea te whakamahi i ngā uku pahuka alumina tino parakore hei tūāpapa hangarau kiko wheua, me te pai o te hototahitanga koiora.
