He tātaritanga hōhonu o te wā maimoatanga wera i muri i te mekameka roera
Kupu Whakataki
I roto i te tukanga whakaputa mekameka roera, he hononga nui te maimoatanga i muri i te wera. Ka pā tika ki te mahi, te roa me te pono o ngā mekameka roera. Mō ngā kaihoko rarawe o te ao, mā te mārama ki te wā me ngā tawhā tukanga e pā ana ki te maimoatanga i muri i te wera o te mekameka roera ka āwhina i a rātou ki te arotake pai ake i te kounga o te hua me te whiriwhiri i ngā kaiwhakarato tika. Ka tūhuratia e tēnei tuhinga ngā hononga me te wā e hiahiatia ana mō te maimoatanga i muri i te wera o te mekameka roera, ā, ka tātarihia ngātahitia me ngā take tūturu.
He tirohanga whānui mō te maimoatanga wera i muri i te mekameka roera
Ko te maimoatanga wera i muri i te mekameka roera e rua ngā mahi matua: te tinei me te whakamahana. Ko tōna kaupapa he whakapai ake i ngā āhuatanga miihini o te mekameka roera, pērā i te pakeke, te pakari me te ātete ki te kakahu, mā te whakamahana pāmahana teitei me te whakamatao tere (tinei) me te whakamahana pāmahana iti (whakamahana). Ka rerekē ngā tawhā wā me te pāmahana o te maimoatanga wera i runga i te rauemi, te rahi me ngā whakaritenga whakamahinga whakamutunga o te mekameka roera.
Ngā taahiraa matua me te wā o te maimoatanga wera i muri i te mekameka roera
1. Te tinei
Ko te tinei te taahiraa tuatahi o te whakamahana i muri i te whakamahana o te mekameka roera. Ko tōna kaupapa he whakarerekē i te hanganga o roto o te mekameka roera mā te whakamatao tere, kia pai ake ai te pakeke me te kaha. He poto noa te wā tinei, engari me tino whakahaere te pāmahana me te tere whakamatao.
Te wā whakamahana: I runga i ngā rauemi rerekē me ngā whakaritenga tukanga, ko te wā whakamahana kei waenganui i te 2 me te 3 meneti. Hei tauira, ina whakamahia te maitai waro-iti iti hei hanga mekameka roera, ko te pāmahana whakamahana he 870-890℃, ā, ko te wā whakamahana he 2-3 meneti.
Wā whakamatao: He poto noa te wā whakamatao o te tine, ā, ka oti i roto i ētahi meneti torutoru. He mea nui te whakahaere i te tere whakamatao nā te mea ka pā tika ki te pakeketanga me te ahotea o roto o te mekameka roera.
2. Te whakamahana
Ko te whakamahana te taahiraa tuarua o te maimoatanga i muri i te whakamahana i ngā mekameka roera. Ko tōna kaupapa he whakaiti i te ahotea o roto i muri i te whakamahana i te pāmahana iti, me te pupuri tonu i te pakeketanga me te pakari. He roa ake te wā whakamahana i te wā whakamahana.
Te whakamahana-mua: Ko te pāmahana o te whakamahana-mua he tata ki te 130℃, ā, ko te wā pupuri he tata ki te 2.5 ki te 3.5 hāora. Mā tēnei taahiraa ka āwhina i te tīmatanga ki te whakau i te hanganga o roto o te mekameka roera.
Te whakamahana tuarua: Ko te pāmahana o te whakamahana tuarua he tata ki te 250℃, ā, ko te wā pupuri he 4 ki te 5 hāora. Ka taea e te whakamahana tuarua te whakapai ake i ngā āhuatanga ā-pūkaha o te mekameka roera me te pupuri i tōna pumau i roto i te whakamahinga roa.
Ngā āhuatanga e pā ana ki te wā maimoatanga wera i muri i te whakamahana o ngā mekameka roera
1. Te hanganga o ngā rauemi
He pānga nui tō te hanganga rauemi o te mekameka roera ki te wā tukatuka me ngā tawhā tukanga i muri i te whakamahana. Hei tauira, he rerekē te pāmahana me te wā tinei o te maitai waro-iti me te koranu iti i ērā o te maitai waro noa. Me whakarerekē te pāmahana whakamahana, te wā pupuri me te tere whakamatao mō ngā hanganga rauemi rerekē kia pai ai ngā āhuatanga miihini.
2. Rahi o te mekameka roera
Ka pā anō hoki te rahi o te mekameka roera ki te wā e tukatukahia ai i muri i te whakamahana. Me roa ake te wā whakamahana me te whakamatao mō ngā mekameka roera nui ake kia rite ai te tohatoha wera me ngā huringa ōrite ki te hanganga o roto.
3. Ngā whakaritenga mō te tika o te tukanga
He rerekē ngā whakaritenga mō te tika me te mahi a ngā mekameka roera i ia whakamahinga. Hei tauira, ko ngā mekameka roera tino tika me te roa o te ora e hiahia ana ki ngā tukanga maimoatanga wera pakari ake me ngā wā tukatuka roa ake. Kei roto i te tukanga maimoatanga wera o tēnei mekameka roera he maha ngā taahiraa pēnei i te whakamahana-mua, te whakakā me te tinei, te whakamatao, te horoi, te whakamahana-mua me te whakamahana tuarua, ā, me tino whakahaere te wā me ngā tawhā o ia taahiraa.
Te tātaritanga tūturu o te maimoatanga wera i muri i te mekameka roera
Take 1: Mekameka rino iti-waro iti-koranu
E ai ki te patent, ina whakamahia te maitai waro-iti iti-koranu hei hanga mekameka roera, ko te tukanga maimoatanga muri-wera penei:
Te tinei: te pāmahana whakamahana 870-890 ℃, te wā whakamahana 2-3 meneti, ā, muri iho ka tinei i te hinu pēhi.
Te whakamātao: te pāmahana whakamātao 200-350 ℃, te wā pupuri ka whakarerekētia kia rite ki ngā whakaritenga motuhake.
Ka taea e tēnei tukanga te whakapai ake i te kaha me te ātete ki te kakahu o te mekameka roera, me te whakaiti anō hoki i te taumaha o te mekameka.
Take 2: Mekameka roera roa-ora tino tika
E ai ki te patent, ko te tukanga maimoatanga wera-muri o te mekameka roera roa-ora tino tika ko ngā mahi e whai ake nei:
Te whakamahana: whakamahanahia te roera ki te 450-500℃, waiho kia mahana mō te 1.5-2.5 hāora.
Te tinei i te waro: whakamahana ki te 900-1000℃, tukuna te acetone me te methanol, whakahaere i te pūmanawa waro i te 1.10±0.05%, waiho kia mahana mō te 3-4 hāora i mua i te tinei.
Whakamatao: Ka whakahaerehia te pāmahana whakamatao i te -10℃ ki te -15℃, ko te wā he 10-20 meneti.
Te whakamahana i mua: te pāmahana 130±5℃, te wā 2.5-3.5 hāora.
Te whakamahana tuarua: pāmahana 250±5℃, te wā 4-5 hāora.
Ka taea e tēnei tukanga te whakapai ake i te ātete ki te kakahu, te ātete ki te waikura me te pakari o te pānga o ngā mekameka roera.
Whakamutunga
Ko ngā tawhā wā me ngā tawhā tukanga o te mekameka roera i muri i te whakamahana he mea nui hei whakarite i te kounga o te hua. Mā te whakahaere tika i te wā whakamahana, te pāmahana me te tere whakamatao, ka taea te whakapai ake i ngā āhuatanga miihini me te roa o te mahi o te mekameka roera. Mō ngā kaihoko rarawe o te ao, mā te mārama ki ēnei tawhā tukanga ka āwhina i a rātou ki te aromatawai pai ake i te taumata hangarau me te kounga o te hua a te kaiwhakarato. I te heke mai, me te whanaketanga tonu o te pūtaiao rauemi me te hangarau maimoatanga wera, ka arotauhia ake te tukanga maimoatanga wera o ngā mekameka roera kia tutuki ai ngā whakaritenga mahi teitei ake.
