Ko HC, he kaihanga matua o ngā wāhanga kākahu kuru taumaha, kua whakarewahia e ia he taputapu mahi-teitei kua whakapai ake.pereti niho kurumengā raina kuru kōne, e aro ana ki ngā āhuatanga mamae o te poto o te ora mahi, te whakakapinga pinepine me te iti o te whai huatanga o te kuru i roto i ngā ahumahi keri, keri rua, hanga kohatu me te tukatuka konganuku. Ko te whakatupuranga hou o ngā wāhanga matua ātete-kakahu ka whakapai ake i te pumau me te hua o ngā taputapu kuru, ka hua mai he painga whakaheke utu nui ki ngā umanga mahi kuru o te ao.
Hei wāhanga matua o ngā taputapu kuru, ko ngā pereti niho me ngā arai kōne te kawenga mō te kuru i ngā rauemi pakeke pērā i te karāneti, te papara, te rino me te quartzite. Ko ngā pereti niho kuru kauae, tae atu ki ngā pereti niho neke me ngā pereti niho pūmau, ka mau i te kaha pānga, te kaha whakaputa me te kakahu waku i te wā e kuru ana i ngā rauemi. Ko ngā pereti niho tuku iho he ngāwari ki te whakarerekē, ki te karawarawa me te ngatata i raro i te mahi taumaha roa, ka hua ake he maha ngā wā ka kati te tiaki taputapu me te pikinga o ngā utu whakahaere.
Ko ngā pereti niho kuru hou kua arotauhia ka whakamahi i te maitai koranu konupora-teitei (Mn13Cr2 me te Mn18Cr2 kua whakapaitia) kua whakauruhia ki te hangarau whakarewa me te maimoatanga wera tika. Ka whakakorea e te hanganga hanga whakauru ngā hapa whakarewa, ā, ka tino whakapaitia te pakeketanga o te mata me te pakari whānui. Ka arotau te hoahoa kōtaha niho ahurei i te ara kuru rauemi, e kore e whakarei ake i te pānga pakaru rauemi anake, ka whakaiti i te tere kuru nui rawa, engari ka roa ake te roa o te ratonga neke atu i te 35% ki te whakataurite ki ngā hua tuku iho. I taua wā, ka whakarite te hoahoa manawanui ā-ahu paerewa i te hototahitanga tino pai ki ngā tauira kuru kauae matua katoa kei te mākete, ka tere te wetewete me te huihuinga me te whakapoto i te wā kore mahi taputapu.
Mō ngā taputapu kuru kōne, kua whakahoutiangā mānumanumengā arai peihana kōpiko(ngā wāhanga mau o te kōne matua) kua tutuki i ngā whanaketanga nui i roto i te hoahoa hanganga me te tauira rauemi. Ka whakawhirinaki ngā mīhini kuru kōne ki te pēhanga me te whakaputa i waenga i te koroka neke me te arai piko pumau hei whakaoti i te kuru pai tuarua me te tuatoru o ngā rauemi. Ka whakamahia e ngā arai kōne hou he hanganga wāhanga-whakawhiti, e whakaoti ana i te raruraru o te mau hapa me te whakakapinga whānui o ngā arai whakauru tuku iho. Me whakakapi noa e ngā kaiwhakamahi ngā wāhanga kua tino tawhito, ka whakaiti nui i ngā utu hoko me te tiaki o ngā wāhanga tāpui.
Mō te mahi a ngā rauemi, ka tāpirihia e ngā wāhanga kuru kōne hou he huānga motuhake ātete-kakahu me te ātete-pānga i runga i te turanga o te maitai konupora parakore-teitei, e whakatutuki ana i te mahi ātete-whakakore me te ātete-ngoi pai rawa atu i raro i te mahi tonu kaha-teitei. E whakaatu ana ngā raraunga tono mara ka taea e ngā wāhanga raina kōne kua whakapai ake te whakatutuki40% te roa o te ora ratongai ngā raina noa i te wā e kuru ana i ngā konganuku pakeke-tiketike, ā, ka piki ake te putanga kuru taputapu ia haora mā te 15% pea nā te hoahoa pihi rūma kuru kua arotauhia.
I kī ngā kaitātari ahumahi ko te roa o te mahi me te tika o te taurite o ngā pereti niho me ngā wāhanga kakahu kōne ngā mea matua e whakatau ana i te whai huatanga o te mahi whānui o ngā raina whakaputa kuru. Ko ngā wāhanga kakahu kāore i te tika ka ngawari ki te whakaputa i te rahi matūriki kuru kāore i te ōrite, te ngoikore o te wiri taputapu, tae atu ki ngā ngaronga kati poto. E whakaatu ana ngā tatauranga ka taea e ngā wāhanga matua kuru ritenga kounga teitei te āwhina i ngā umanga keri me te whakakotahi ki te whakaiti i ngā utu whakahaere whānui mā te 20%-30% ia tau.
I tēnei wā, kua oti katoa te hanga papatipu i ngā pereti niho hou me ngā wāhanga pakaru kōne hou, e kapi ana i ngā whakaritenga katoa e tika ana mō ngā pakaru kauae iti, waenga me te nui me ngā pakaru kōne. Kua paahitia e ngā hua katoa ngā whakamātautau kounga tino pakari me te manatoko mahi mara, ā, he whānui te whakamahi mō te pakaru maina, te tukatuka rauemi hanga rori, te hangarua para hanga me ētahi atu āhuatanga. Ka whakaratohia e te kaihanga ngā ratonga tukatuka ritenga kia rite ki ngā rauemi pakaru a te kiritaki, ngā tauira taputapu me ngā tono whakaputa, ka tutuki ai ngā otinga taurite kotahi-mutu mō ngā wāhanga pakaru ka taea te mau.
Mā te whakapai tonu i ngā taputapu keri me te hanga o te ao kia eke ki te taumata teitei, te penapena pūngao me te iti o te whakamahinga, ka noho ko ngā taputapu matua kuru mahi teitei me te pakari hei whiringa matua o te umanga. Mā te whakapai tonu i ngā pereti niho me ngā raina kōne ka whakatairanga ake i te whanaketanga atamai me te whai hua o te umanga tautoko taputapu kuru o te ao.
