Ko te karāpeti whānui, e mōhiotia ana ko te karāpeti vermicular, he matū tioata e whakamahi ana i ngā tikanga ā-tinana, ā-matū rānei hei whakauru i ngā matū kore-waro ki roto i ngā rauemi nanowaro kua whakauruhia ki te karāpeti taiao, ā, ka honoa ki ngā papa whatunga hexagonal waro, me te pupuri tonu i te hanganga o te paparanga karāpeti. Ehara i te mea ka pupuri noa i ngā āhuatanga ā-tinana me te matū pai o te karāpeti, pērā i te ātete pāmahana teitei, te ātete waikura, te rere o te neutron, te hihi-X me te hihi-kama mō te wā roa. He āhuatanga ā-tinana me te matū pai anō hoki, pērā i te tauwehenga waku iti, te pai o te whakahinuhinu-ā-roto, te kawe hiko me te wera, me te anisotropy. Heoi anō, nā te taunekeneke i waenga i te rauemi kua whakauruhia me te paparanga karāpeti, ka whakaatuhia e te karāpeti whānui ngā āhuatanga hou kāore i te karāpeti taketake me te rauemi kua whakauruhia, ā, ka wikitoria i te pakarukaru me te ātete pānga o te karāpeti taiao. Ko ngā ētita karāpeti Furuite e whai ake nei e whakapuaki ana i te whakaurunga o ngā tikanga hanga ahumahi me ngā whakamahinga o te karāpeti whānui:
1. Ngā tikanga hangai e whakamahia whānuitia ana i roto i te ahumahi
①Te whakahāora matū
Ngā Painga: He tikanga whānuitia te whakamahi i te waikura matū, ā, kua roa nei e whakamahia ana i roto i te ahumahi. Nō reira, he mārama ngā painga, he hangarau pakari, ā, he iti te utu.
Huakore: Ko te waikawa whanariki kukū te nuinga o te wā e pau ai te waikawa. He parahanga hau kino a Sox i roto i te tukanga whakaputa, ā, ka waikura hoki ngā taputapu hanga i ngā toenga i roto i te hua.
②Te whakahāora hikohiko
Pērā i te waikura matū, ko tētahi o ngā tikanga hanga ahumahi noa mō te karāwhata whakawhanui.
Ngā Painga: Kāore e hiahiatia he tāpiri i ngā waikura kaha, pērā i ngā waikawa kaha, ā, ka taea te whakahaere i te tauhohenga mā te whakarerekē i ngā tawhā pērā i te iahiko me te ngaohiko. He māmā noa iho ngā taputapu hanga, he nui te nui o te hanga, kāore te irahiko i poke, ā, ka taea te whakamahi anō.
Ngā Huakore: He ngoikore ake te pumau o te hua kua hangaia i ērā atu tikanga, e hiahia ana ki ngā taputapu teitei ake, ā, he maha ngā āhuatanga e pā ana ki te kounga o te hua. I ētahi wā, ka tino heke te rōrahi whānui o te hua nā te pikinga o te pāmahana taiao. Hei tāpiri, tera anō ngā tauhohenga taha i ngā iahiko teitei i roto i ngā otinga wai, nō reira he uaua ki te whiwhi i ngā matū ota tuatahi.
2. Ngā umanga whakaputa matua me te kaha whakaputa
Kua tipu te hanga o ngā hua karāpeti whānui i tōku whenua mai i te tīmatanga ki te neke atu i te 100 ngā kaihanga, me te putanga ā-tau tata ki te 30,000 tana, ā, he iti te kukū o te mākete. Waihoki, ko te nuinga o ngā kaihanga he whakakī hiri iti te mutunga, he onge te whakamahinga i roto i ngā hiri motuka me ngā rama rererangi karihi. Heoi, me te whanaketanga o te hangarau ā-rohe, ka piki haere te ōwehenga o ngā hua teitei.
3. Te hiahia o te mākete me te matapae mō ngā rauemi hiri
I tēnei wā, ko te karāpiti whakawhanui te mea e whakamahia nuitia ana hei rauemi hiri waka, pērā i ngā hiri rango, ngā hiri putanga whakauru me te putanga hau, me ētahi atu. Ko ngā rauemi hiri karāpiti whakawhanui i tōku whenua e whakamahia nuitia ana hei whakakī hiri. I tēnei wā, kua whakawhanakehia te karāpiti whakawhanui me te iti o te ihirangi waro, ka taea te whakaiti i te utu whakaputa o te karāpiti whakawhanui, ā, ka whakakapia te asbestos i runga i te tauine nui me te pikinga o te tono. I tētahi atu taha, ki te taea te whakakapi wāhanga i ngā rauemi hiri kirihou, rapa me te whakarewa, ka nui ake te tono ā-tau mō ngā rauemi hiri karāpiti whakawhanui.
I roto i te umanga motuka, e 2~10kg te nui o te karāpeti whānui e hiahiatia ana mō ia pēke pane rango, mō ia pēke urunga hau me te pēke putanga hau, ā, e 20~100 tāne te nui o te karāpeti whānui e hiahiatia ana mō ia 10,000 motuka. Kua uru te umanga motuka o Haina ki tētahi wā whanaketanga tere. Nō reira, he tino whāiti tonu te hiahia ā-tau o tōku whenua mō ngā rauemi hiri karāpeti whānui.
