E mōhiotia whānuitia ana ngā wāhanga miihini karāneti hei wāhanga nui i roto i ngā mīhini tino tika, nā te mea he tino pumau, he ātete ki te kakahu, me te ātete ki te waikura. Mō ngā kaihoko me ngā miihini o te ao e rapu ana i ngā otinga miihini karāneti pono, he mea nui te mārama ki ngā whakaritenga hangarau matua hei whakarite i te mahi hua me te angitu o te kaupapa. Kei raro nei, ka whakamāramahia e ZHHIMG—tō hoa pono i roto i ngā wāhanga karāneti tino tika—ngā paerewa hangarau me whai mō ēnei wāhanga tino nui.
1. Kōwhiringa Rauemi: Te Pūtake o te Kounga
Ka tīmata ngā wāhanga miihini karāhe mahi-teitei ki ngā rauemi mata kounga teitei. Ka whakamahia e mātou ngā toka matotoru, angiangi pērā i te kapara, te diabase, me te karāhe, me ngā whakaritenga e whai ake nei:
- Te nui o te biotite ≤ 5%: Ka whakarite kia iti te horapa o te wera me te pumau o ngā āhuatanga.
- Tauwehenga pīngore ≥ 0.6×10⁴ kg/cm²: Ka whakamanahia te kaha ki te kawe kawenga me te ātete ki te whakarerekētanga.
- Te mimiti wai ≤ 0.25%: Ārai i te kino i puta mai i te makuku, ā, ka mau tonu te mahi i roto i ngā taiao makuku.
- Te pakeke o te mata o te mea mahi ≥ 70 HS: He ātete pai ki te kakahu mō te whakamahinga roa i roto i ngā āhuatanga mahi auau teitei.
2. Te Pakari o te Mata: Te Tika mō ngā Mata Mahi
Ka pā tika te āhua o te mata ki te taunga me te mahi a te wāhanga ki ngā mīhini. E hangai ana ā mātou paerewa ki ngā whakaritenga o te ao mō te tika:
- Ngā mata mahi: Ko te taratara o te mata kei waenganui i te 0.32 μm me te 0.63 μm, e whakarite ana i te pai o te pa atu ki ngā wāhanga e hono ana, me te whakaiti i te waku.
- Ngā mata taha: Te taratara o te mata Ra ≤ 10 μm, te whakataurite i te tika me te whai huatanga o te hanga mō ngā wāhi kāore i te tino hira.
3. Papatahi me te Tūnga Poutū: He mea nui mō te Tika o te Huihuinga
Hei whakarite kia pai te whakaurunga ki roto i tō mīhini, ka tutuki i ā mātou wāhanga karāhe ngā whakaritenga āhuahanga tino pakari:
- Tirotiro papatahi: Mō ngā taumata katoa, ka whakamahia e mātou te tikanga whakarara, te tikanga whatunga rānei hei whakamātautau i te papatahi o te mata. Ko te rerekētanga o te mata e whakaaetia ana e whai ana i ngā whakaritenga i roto i te Ripanga 2 (e wātea ana mēnā ka tonoa), kia kore ai he rerekētanga e pā ki te huihuinga, ki te mahi rānei.
- Te manawanui poutū:
- Te tūnga poutū i waenga i ngā mata taha me ngā mata mahi.
- Te tūnga poutū i waenganui i ngā mata taha e rua e tata ana.
E tutuki ana i ngā paerewa o te taumata 12 e ai ki te GB/T 1184 (he rite ki ngā paerewa o te ao), e whakapūmau ana i te tika o te whakaritenga i te wā tāutanga.
4. Whakahaere Hapa: Kore Whakahekenga ki te Mahi
Mā te hapa i runga i ngā mata tino kino ka raru pea ngā mīhini. Ka whakatinanahia e mātou ngā paerewa hapa tino pakari mō ngā wāhanga karāhe katoa:
- Ngā mata mahi: Kāore e tino āraia ngā hapa e pā kino ana ki te āhua, ki te mahi rānei, tae atu ki ngā kōhao onepu, ngā mirumiru hau, ngā kapiti, ngā whakaurunga, te pūngao whakaheke, ngā karawarawa, ngā pakaru, ngā paru waikura rānei.
- Ngā mata kāore e mahi ana: Ka whakaaetia ngā poka iti, ngā maramara kokonga rānei mēnā he mea whakatika ā-ngaio, ā, kāore e pā ki te hanganga, ki te huihuinga rānei.
5. Ngā Taipitopito Hoahoa: I Whakaritea mō te Whakamahinga Whaihua
Ka arotauhia e mātou te hoahoa o ngā wāhanga kia taurite ai te tika me te whakamahinga, me ngā whakaritenga motuhake mō ia taumata:
- Ngā kakau whakahaere: Mō ngā wāhanga o te Tau 000 me te Tau 00 (tino tika), kāore i te tūtohutia ngā kakau. Mā tēnei ka ārai i te ngoikore o te hanganga, i te rerekētanga rānei ka pā kino ki ō rātou manawanui tino piri.
- Ngā kōhao/ngā awaawa miro: Mō ngā wāhanga Taumata 0 me Taumata 1, mēnā e hiahiatia ana ngā kōhao, ngā awaawa rānei miro ki te mata mahi, me noho ō rātou tūranga ki raro i te taumata o te mata mahi. Mā tēnei ka ārai i te pokanoa ki te wāhi pa mahi o te wāhanga.
