I roto i ngā mara matatau pēnei i te hanga haurua-ira, te tirotiro whatu tika, me te tukatuka nanomaterial, ko te pumau me te tika o ngā taputapu e whakatau tika ana i te kounga o te hua me te whai huatanga o te whakaputa. Ko ngā papa tika o te karāhe, me te mahi whakaiti e ono ngā wā i te rino maka, kei te noho hei tino pai hou i roto i te umanga. He aha ngā uara kore e taea te whakakapi kei muri i tēnei painga mahi? Me tūhura ngātahi tātou i ngā painga matua o te whiriwhiri i ngā papa tika o te karāhe.
1. He taurangi tino tika, kāore he raruraru o ngā hapa iti
I tēnei wā o te hangahanga nano, ka taea e te wiri iti te arahi ki te pakaru o te hua. Ina tūtaki te turanga rino maka ki te wiri i puta mai i te mahi a te taputapu, i te pokanoa rānei o te taiao o waho, nā te kore e ranea te mahi whakaiti, ka uaua te tere memeha o te kaha wiri, ka hua ake te nekehanga, te ru rānei o ngā wāhanga matua o te taputapu. Ka taea e te papa tino tika o te karāhe te huri i te kaha wiri hei kaha wera hei whakamarara i roto i te wā poto, ka pehi pai i te tuku me te whakanui i te wiri.
Hei tauira, tangohia te mīhini whakaahua haurua-irahiko. Whai muri i te whakamahi i te tūāpapa tika o te karāhe, kua heke te kaha wiri o te arotahi mai i te ±8μm ki te ±1.3μm, ka whakaitihia te hapa whānui rārangi o te tauira maramara mā te 75%, ā, ka whakapai ake i te tika o te hanga o te maramara. I roto i te tirotiro whatu tika, ka taea te whakarite kia mau tonu te arotahi whatu o te taputapu tirotiro, ka karo i te pōuriuri o te ahua me te pekapeka o ngā raraunga i puta mai i te wiri, ā, ka kore e huna ngā hapa iti i te taumata 0.1μm.
Tuarua, he roa rawa tōna ora ratonga, ā, ka whakaiti i te utu katoa.
I raro i te wiri me te pānga roa, ā, he maha tonu, ka ngawari te pakaru o te turanga rino maka ki roto, ka heke te kaha o te hanganga. Me whakakapi i muri i te 3 ki te 5 tau, ka nui ake te wā e kore ai e whakamahia ngā taputapu, engari ka nui hoki ngā utu tiaki me te whakakapinga. He mea hanga te karāhe i ngā tioata kohuke pērā i te kuata me te feldspar, e honoa tata ana mā roto i ngā hononga ioni me te hononga honohono. He matotoru, he ōrite te hanganga, ā, he kaha te ātete ki te ngenge.
Ahakoa ngā tekau mano o ngā huringa wiri, ka taea tonu e te papaaho tika o te karāhe te pupuri i ngā āhuatanga ā-tinana me ngā āhuatanga ā-mīhini pumau, ā, ka taea e tōna roanga mahi te neke atu i te toru ngā wā i tērā o te turanga rino maka. E whakaatu ana ngā tatauranga mai i tētahi umanga hanga taputapu tika, i muri i te whakamahinga o ngā papaaho tika o te karāhe, kua heke te auau o te tiaki taputapu mā te 60%, ā, neke atu i te kotahi miriona yuan te penapena utu ā-tau.
Tuatoru. He tino pai te urutau ki te taiao, he ngāwari te whakahaere i ngā āhuatanga mahi uaua
I roto i te taiao whakaputa tūturu, ka pāngia te mahi a ngā taputapu e ngā āhuatanga pēnei i te huringa pāmahana, te pokanoa hikohiko, me te waikura matū. He teitei te tauwehenga whānui wera o te turanga rino maka, ā, he ngāwari ki te whakarerekē i ngā āhuatanga i raro i ngā piki me ngā heke o te pāmahana, ka pā ki te tika o ngā taputapu. I taua wā, he ngoikore te ātete ki te waikura, ā, he ngāwari ki te waikura me te whakarerekē i raro i te mimiti o ngā matū.
He tino iti te tauwehenga o te whakawhanuitanga wera o ngā papaaho tika o te karāhe (1/20 noa iho o te rino maka), ā, ka taea e ia te ātete i ngā awe o ngā huringa pāmahana. He pumau ōna āhuatanga matū, ā, kāore e tauhohe ki ngā matū waikawa, kawakore rānei, ā, ka taea te mahi pumau i roto i ngā taiao uaua pēnei i ngā awheawhe haurua-ira me ngā taiwhanga matū. Hei tāpiri, kāore te karāhe e kawe hiko, kāore hoki e aukume, ā, kāore e pāngia e te pokanoa hikohiko, e whakarite ana i te pumau o te mahi taputapu.
Tuawhā, kua whakamanahia e ngā mahi ahumahi he āwhina i te whakataetae a ngā umanga kia anga whakamua.
Kua tino whakaatuhia e ngā mahi a ngā umanga matua maha i roto i ngā momo ahumahi te uara o ngā papaaho tika o te karāhe. Whai muri i te whakakapinga o te papaaho tika o te karāhe i tētahi wheketere haurua-ā-ao nui, ka piki ake te tere hua maramara mai i te 78% ki te 92%, ā, ka piki ake te kaha whakaputa mā te 30%. Whai muri i te tango a tētahi kaihanga taputapu whatu kounga teitei i tēnei papaaho, ka eke te tika o te kitenga o āna hua ki te taumata ārahi o te umanga, ā, ka nui ake ngā ota o te ao i riro mai i a ia.
I tēnei wā, e kaha haere ana te whakataetae i roto i te hanga tino tika, ko te whiriwhiri i ngā papaaho tino tika o te karāhe he whakapai ake i te mahi a ngā taputapu whakaputa, engari he whakatau matua hoki mā ngā umanga ki te whakapai ake i te kounga o ngā hua, ki te whakaiti i ngā utu me te whakarei ake i te whakataetae mākete. I te haere tonu o te hangarau, ka whai wāhi nui ngā papaaho tino tika o te karāhe ki ngā mara maha atu, hei whakatairanga i te ahumahi kia whanake ki te tika me te whai huatanga teitei ake.
