Ngā Mahi me ngā Whakamahinga o te Paura Iti o te Kōrunuma Parauri i roto i te Ahumahi Paninga
I te kōrero mō ngā "tāngata uaua" i roto i te umanga paninga,paura moroiti kōrunuma parauri Koia tonu te mea tino pai. Kaua e tinihangatia e tōna āhua pouri; he rauemi maha-whakamahinga, ā, he kaha hoki i roto i te ao paninga! E mōhio ana ngā kaihanga peita mātau ko te tāpiri i te paura moroiti parauri ko te mea nui ki te whakatutuki i te ātete ki te kakahu me te roa.
He rite noa te rahi o te paura iti o te korundum parauri ki te maikoronawaikura konumohe tata ki te 95% te ihirangi. Ka whakamahia i roto i te oumu hiko mai i ngā rauemi mata pēnei i te bauxite me te coke i ngā pāmahana neke atu i te 2,000 nekehanga Celsius. He rite te tukanga ki te tunu kai: ko te wera tika me te taurite tika o ngā kai ka taea te whakaputa i tētahi hua pai. Me te pakeke Mohs o te 9, tuarua ki te taimana anake, e kiia ana ko te rauemi tino uaua i roto i te umanga paninga.
E maumahara ana ahau i tērā tau i tā mātou haerenga ki tētahi wheketere paninga papa ahumahi, ka tohu te kaiwhakahaere o te awheawhe ki te papa hou kua oti, ā, ka whakamanamana mai ki a mātou, "Tirohia? He mea hanga tēnei papa ki tētahi paninga kua whakakikoruatia kipaura kōrunuma parauri"... E rere ana ngā forklifts i runga i ia rā, ā, kāore anō kia rakurakuhia mō ngā tau e toru neke atu!" I muri mai, ka mōhio mātou kei roto i tā rātou paninga he 20% te paura korundum parauri 325-mata, ā, kua piki ake tōna ātete ki te kakahu neke atu i te toru ngā wā i tērā o ngā paninga noa.
I roto i te ao o ngā paninga ārai-waikura, he mahi nui tā te paura korundum parauri. Ko ōna taha koi ka hanga he hanganga tautoko pumau i roto i te paninga, pērā i te "anga" mō te paninga. I te tau kua hipa, i hiahiatia he paninga e ātete ana ki te waikura o te wai me te kaha ki te tu atu i te waku o ngā taputapu i roto i tētahi kaupapa papaaho moana. Ko te tauira toa i whakamahi i te paura korundum parauri kua rongoatia motuhake, ā, i rongo ahau he roa te roa o te noho i roto i te wai moana me te kore e pakaru te peita.
Ko te wāhanga tino uaua o te hangarau ko te ōwehenga o te paura korundum parauri i tāpirihia ki te paninga. Mēnā he nui rawa, ka matotoru rawa te peita, ā, ka uaua ki te pani; mēnā he iti rawa, ka kore e whai hua. E whakamahi ana tētahi tohunga toi i tētahi kupu whakarite oraora: "He rite ki te pokepoke paraoa. Mēnā he nui rawa te wai, tāpirihia he paraoa; mēnā he nui rawa te paraoa, tāpirihia he wai. Me kimi e koe te taurite tino tika." I te nuinga o te wā, ko te horopeta kei waenga i te 15% ki te 30% i runga i te whakamahinga o te peita. Hei tauira, ka nui ake te whakamahinga o ngā peita papa, engari he iti ake te whakamahinga o ngā peita moana.
Paura moroiti kōrunuma parauriKei te wātea mai i ngā rahi rerekē, mai i te 800 ki te 2000 mata. Ka rerekē ngā pānga o te mata, ka rerekē hoki. Ka whakamahia ngā matūriki matotoru mō ngā tono ārai-paheke, engari he pai ake ngā matūriki matotoru mō ngā paninga o runga. I whakapuaki mai tētahi kaihanga paninga papa hākinakina i ō rātou wheako: ka whakamahia e rātou te 240 mata mō te paninga turanga hei whakapai ake i te piri me te 800 mata mō te paninga o runga hei whakapai ake i te ātete ki te kakahu. He tino pai ngā hua o tēnei huinga.
Heoi, me āta tupato i te wā e pania ana. He tino teitei te taumaha motuhake o te paura iti korundum parauri, ā, he ngāwari ki te tau, nō reira me tāpiri he matū ārai tau tika i te wā e hanga ana i te peita. He mea nui anō hoki te whakaoho, nā te mea ka pā te tohatoha kore taurite ki te hua whakamutunga. I pāngia tētahi wheketere e tēnei ngaronga. Nā te korenga o te wā whakaranu, he koretake te kukū o te peita i waenga i ngā paparanga o runga me raro, ā, ka rerekē te tae i muri i te paninga, ā, me mahi anō.
I te mea kua tino kaha haere ngā whakaritenga tiaki taiao, kua piki haere te kaha o te tukanga whakaputa opaura kōrunuma paraurikei te whakapai tonu. He maha ngā kaihanga e whakatairanga ana i ngā hua iti-pūngao hei whakaiti i te parahanga pūngao i te wā o te tukanga whakaputa. Kei te rangahau hoki ētahi kamupene i ngā hangarau whakarerekētanga mata hei whakahohe i te paura kōrundum parauri kia pai ake te piri ki ngā kapia me te whakarei ake i te mahi whānui o ngā paninga.
I te nuinga o te wā, he whānui ngā tūmanakohanga mō te whakamahinga o te paura kōrunuma parauri i roto i te umanga paninga. Mai i ngā papa ki ngā kaipuke, mai i ngā paipa ki ngā tāke rokiroki, ka kitea i ngā wāhi katoa. I te putanga tonu mai o ngā rauemi hou me ngā tukanga hou, kei te whiwhi kaha hou anō hoki tēnei "rauemi tawhito".
Nō reira, ā tērā wā ka tūtaki koe ki tētahi paninga e hiahia ana ki tētahi paninga tino ātete ki te kakahu, ā, he roa hoki, ngana ki te tāpiri i ētahi paura kōrunuma parauri. Tērā pea ka taea e tēnei panonitanga iti te whakanui ake i te mahi a tō hua! Heoi anō, i roto i te mahi, he maha ngā tauira whai hua ka kitea mā te whakamātautau me te hapa.
