I roto i te "wheketere nui" o te hanga maramara, kei ia wafer te rahi o te maikuku he ara iahiko tino tika, ā, ko te kī ki te whakatau mēnā ka taea te hanga tika i ēnei ara iahiko kei roto i tētahi kōhatu koretake - ko te karāneti tēnei. I tēnei rā, me kōrero tātou mō te "patu ngaro" o te karāneti - tōna kaha ki te whakamākū - me pēhea e riro ai hei "anahera kaitiaki" o ngā taputapu matawai wafer.
He aha te whakamākū? Ka taea hoki e ngā kōhatu te "mokomoko i ngā wiri"?
He tino ngaio te ahua o te whakamātao, engari he tino māmā noa iho te kaupapa. Whakaarohia ka mutu ohorere koe i a koe e oma ana. Ki te kore he urunga, ka tere whakamua tō tinana nā te koretake. Ā, he rite te whakamātao ki te ringa e kore e kitea, e āwhina ana i a koe ki te "pēhi" tere. Ko te hanganga o roto o te karāhe he mea hanga mai i ngā tioata kohuke kua rarangahia pērā i te kuata me te feldspar, ā, he maha ngā kapiti iti me ngā pūwāhi waku i waenganui i ēnei tioata. Ina tukuna ngā wiri o waho ki te karāhe, ka tīmata ēnei kapiti me ngā pūwāhi waku ki te "mahi", ka huri i te kaha o ngā wiri hei kaha wera, ā, ka marara haere, ka mutu wawe ngā wiri. He rite tonu tēnei ki te tāuta i tētahi "kaikōmi wiri nui" ki runga i te taputapu, kia kore ai e "ruru ringa".
Matawai Wafer: Mā te hapa iti ka arahi pea ki tētahi hapa nui
He rite ngā taputapu matawai angaanga ki ngā kāmera tino tika e "tango pikitia" ana i ngā angaangaanga, e kite ana, e tuhi ana hoki i ngā tauira ara iahiko i te nanoscale. Heoi, i te wā e whakahaerehia ana te taputapu, ka puta he wiri auau teitei i te hurihanga o te motuka me te nekehanga o ngā wāhanga miihini. Ki te kore e whakahaeretia ēnei wiri, ka "pōuri" te karu matawai pērā i te kāmera kore pumau, ka hua ake he raraunga kitenga hē, ā, ka pakaru tika te angaangaangaanga katoa.
Ina pāngia te turanga whakarewa noa e te wiri, he maha tonu te "pānga kaha ki te kaha", me te whakaata i te wiri ki roto i te whakarewa, ka kaha haere te wiri. Nā tōna kaha whakamātao pai, ka taea e te karāneti te mimiti i te neke atu i te 80% o te kaha wiri. E whakaatu ana tētahi tauira tūturu o tētahi wheketere haurua-ira i mua i te whakakapinga o te turanga karāneti, he pōuriuri ngā taha o ngā whakaahua wafer i tangohia e ngā taputapu matawai, me te rerekētanga tae atu ki te ±3μm. Whai muri i te whakawhiti ki te turanga karāneti, i tino pai ake te māramatanga o te ahua, i whakaitihia te rerekētanga ki te ±0.5μm, ā, i piki ake te tere hua mai i te 82% ki te 96%!
Te raruraru o te haruru: Me pēhea te "whakakore i te tūponotanga" a te karāneti?
Haunga te wiri o ngā taputapu tonu, ko ngā wiri iti mai i te taiao o waho (pērā i te mahi a ngā mīhini i te taha, i ngā takahanga waewae rānei o ngā kaimahi e hikoi ana) ka raru pea. Ina rite te auau wiri o waho ki te auau o te taputapu tonu, ka puta te haruru, pērā i te rūrū i te tiēre, ka nui ake te kaha, ka nui ake te rūrū. Ko ngā āhuatanga whakamākū o te karāhe he rite ki te whakatakoto "puru taringa ārai-oro" ki runga i ngā taputapu, ka whānui ake te whānuitanga auau haruru o ngā taputapu, ā, ka iti ake te tūponotanga kia ōrite ki te ao o waho. E whakaatu ana ngā raraunga i muri i te whakamahinga o te turanga karāhe, kua heke te mōrearea o te haruru o ngā taputapu mā te 95%, ā, kua toru ngā wā kua pai ake te pumau!
Te māramatanga o te "whakaiti" i te ao
Ina hoki, he mea tino noa te kaupapa o te whakamāmā i roto i te oranga o ia rā. Mā ngā ārai ru o te motuka ka taea e tātou te taraiwa maeneene i runga i ngā rori pūkeko, ā, mā te mahi whakakore haruru o ngā paneoro ka taea te aukati i te haruru o waho. Ka tutuki i ēnei katoa te pumau mā te "mimiti i te pūngao". Kua tino kaha te karāti ki tēnei kaha, ā, kua waiho hei rauemi matua e kore e taea te whakakore i roto i te mara o te hanga maramara.
A te wā ka kite koe i te karāneti, kaua e whakaaro noa he kōhatu noa iho! I roto i te ao matatau o te hanga haurua-ira, ko ēnei rauemi āhua noa iho, me ō rātou "mana nui" ahurei, ka akiaki tonu i te hangarau ki mua.
