I roto i te mara o te whakahaere nekehanga tino tika, kua waiho te waeine nekehanga tino tika o te hau mānu hei whiringa pai mō te maha o ngā mahi hanga me ngā rangahau pūtaiao teitei nā te mea he kore-waku me te tino tika ōna āhuatanga nekehanga. Ko te whakaurunga o te turanga tino tika o te karāhe hei wero i te kaha kaha hei whakapai ake i tana mahi, engari kāore te whakakotahitanga o ngā mea e rua i te tino tika.
Tuatahi, ngā painga nui
Pūmautanga Tino Pai: Whai muri i ngā miriona tau o ngā huringa whenua, he matotoru, he ōrite hoki te hanganga o roto o te karāhe, ko te nuinga he quartz, he feldspar me ētahi atu kohuke e hono tata ana. Mā tēnei hanganga ahurei ka tino pumau te turanga karāhe. Ahakoa ngā pokanoa o waho, pērā i te wiri i puta mai i te whakahaere o ngā taputapu nui e karapoti ana me te piki me te heke o te pāmahana taiao, ka taea e te turanga karāhe te aukati me te whakaiti. I roto i te awheawhe hanga maramara hiko, he maha ngā mahi a ngā taputapu mīhini me ētahi atu taputapu, ā, ka taea e te turanga karāhe te whakaiti i te kaha wiri o te waeine nekehanga tino tika e tukuna ana ki te hau mānu mā te neke atu i te 80%, ka whakarite i te nekehanga maeneene o te waeine, ka whakarato i te turanga pumau mō ngā tukanga tino tika pērā i te tuhi me te whakairo i roto i te tukanga hanga maramara, ā, ka tino whakapai ake i te hua o te hanga maramara.
Te pupuri i te tino tika: Ko te waeine nekehanga tino tika o te pōtaka hau e hiahia ana kia tino tika, ā, ko te painga o te iti o te tauwehenga whānui o te turanga karāhe he mea nui ki tēnei. Ko te tauwehenga whānui wera o te karāhe whānui ko te 5-7 ×10⁻⁶/℃, he iti iho i ngā rauemi whakarewa noa. Ina huri te pāmahana, he iti noa te rerekētanga o te rahi o te turanga. I roto i te mara o te whetū, ka taea e te waeine nekehanga tino tika o te pōtaka hau mō te whakatikatika pai o te arotahi karāhe, me te turanga karāhe, te whakarite kia mau tonu te tika o te tūnga o te arotahi i te taumata iti-micron ahakoa he nui te rerekētanga pāmahana i waenga i te awatea me te pō, ka āwhina i ngā kaimātai whetū ki te mātakitaki mārama i ngā tinana rangi tawhiti.
He ātete pai ki te kakahu me te roa o te ora: Ahakoa ka whakaitihia e te waeine nekehanga tino tika o te hau e rere ana te waku tika i te wā e whakamahia ana, kei te mau tonu te mōrearea o te kakahu i te whakamahinga roa. He teitei te pakeke o te karāhe, ka taea e te pakeke Mohs te eke ki te 6-7, he kaha te ātete kakahu. I roto i te taiwhanga pūtaiao rauemi, ko te waeine nekehanga tino tika o te hau e whakamahia pinepine ana, ka taea e te turanga karāhe te ātete pai i te waku o te reti hau e rere ana, ki te whakaritea ki te turanga whakarewa noa, ka taea te whakaroa i te huringa tiaki o te waeine neke atu i te 50%, te whakaiti i ngā utu tiaki taputapu, me te whakarite i te haere tonu o te mahi rangahau pūtaiao.
Tuarua, kei reira ngā ngoikoretanga
Te utu nui: He nui te utu mō te hoko rauemi mata karāhe kounga teitei, ā, he uaua ake te keri, te kawe me te tukatuka, me ngā taputapu ngaio me ngā hangarau. Mai i te keri i te konganuku karāhe tika ki te tukatuka hei turanga waeine nekehanga hau tino tika e tutuki ana i ngā whakaritenga o te tino tika, he maha ngā tukanga pai e uru ana, pērā i te tapahi tino tika, te huri, te whakakanapa, me ētahi atu, ka nui ake te utu hanga o te turanga tino tika o te karāhe. Ki te whakatauritea ki ētahi atu rauemi pērā i te konganuku, ka taea te piki ake te utu, ka whakawhāiti i tōna whakamahinga nui ki tētahi whānuitanga, inā koa mō ngā umanga iti, ngā whare rangahau pūtaiao rānei he iti te tahua.
Taumaha taumaha: He nui te matotoru o te karāhe, tata ki te 2.6-3.1g /cm³, ka hua ake he turanga karāhe taumaha ake. I roto i te tukanga tāutanga me te whakahaere taputapu, me whakamahi ngā taputapu hiki ngaio me te kaha tangata, ka nui ake te uaua o te tāutanga me te utu kawe. I ētahi wā e hiahia ana kia nui te ngāwari o te tahora ā-wāhi o ngā taputapu, ka aukati hoki te turanga taumaha i te nekehanga watea me te tāuta anō o te waeine nekehanga tino tika o te hau mānu, ka pā ki te whai huatanga me te urutau o ngā taputapu.
He uaua ki te tukatuka: he tino pakeke, he pakarukaru hoki te karāneti, ā, he tino tino pakari ngā whakaritenga mō ngā taputapu tukatuka me ngā tukanga. I roto i te tukanga miihini, he ngāwari te pakaru, te pakaru me ētahi atu hapa, ā, he uaua ki te whakarite i te tika o te miihini me te kounga o te mata. Hei whakatutuki i te papatahi me te tika teitei e hiahiatia ana e te waeine nekehanga tino tika o te hau mānu, he maha ngā whakamātautau me ngā whakatikatika e hiahiatia ana i te wā tukatuka, ā, he roa te huringa tukatuka, ā, he teitei te tere whakakorenga, e piki ake ai te utu whakaputa me te utu wā.
He tino pai ngā painga o te waeine nekehanga tino tika me te turanga tino tika o te karāhe, arā, te pumau me te tika, he mea e tika ana mō ngā mara tino pai me ngā whakaritenga tino tika, engari ko te papa poto pēnei i te utu, te taumaha me te uauatanga tukatuka me whai whakaaro whānui hoki i roto i ngā tono mahi, ā, ka whakatauhia he kōwhiringa whaitake i muri i te paunatia o ngā painga me ngā ngoikoretanga.
