Ngā Whakaritenga Hangarau mō ngā Wāhanga Ā-ringa o te Māpere me te Karāneti

He whānuitia te whakamahinga o ngā wāhanga miihini o te māpere me te karāneti i roto i ngā mīhini tino tika, ngā taputapu ine, me ngā papa ahumahi nā te mea he tino pumau, he tino pakeke, he ātete hoki ki te pakaru. Hei whakarite i te tika me te roa, me whai i ngā whakaritenga hangarau tino pakari i te wā hoahoa me te hanga.

Ngā Whakatakotoranga Hangarau Matua

1. Hoahoa Whakahaere
   Mō ngā wāhanga mīhini māpere o te Wāhanga 000 me te Wāhanga 000, kāore i te tūtohutia kia tāutahia he kakau hiki hei pupuri i te pono me te tika o te hanganga.

2. Te Whakatika i ngā Papa Kāore e Mahi ana
   Ka taea te whakatika i ngā pona iti, i ngā kokonga pakaru rānei o ngā mata kāore e mahi ana, engari kaua e pāngia te kaha o te hanganga.

3. Ngā Whakaritenga Rauemi
   Me hanga ngā wāhanga mā te whakamahi i ngā rauemi matotoru, matotoru pērā i te gabbro, te diabase, te māpere rānei. Ko ngā tikanga hangarau ko:

   • I raro iho i te 5% te ihirangi o te biotite

   • Te modulus elastic nui atu i te 0.6 × 10⁻⁴ kg/cm²

   • Te tere mimiti wai i raro i te 0.25%

   • Te pakeke o te mata mahi i runga ake i te 70 HS

4. Te Pākari o te Mata

   • Te taratara o te mata mahi (Ra): 0.32–0.63 μm

   • Te taratara o te mata taha: ≤10 μm

5. Te Manawanui Papatahi o te Mata Mahi
   Me tutuki te tika o te papatahi ki ngā uara manawanui kua tohua i roto i ngā paerewa hangarau e rite ana (tirohia te Ripanga 1).

6. Papatahi o ngā Mata Taha

   • Me tutuki te ātete papatahi i waenga i ngā mata taha me ngā mata mahi, tae atu ki waenga i ngā mata taha e rua e tata ana, ki te Wāhanga 12 o GB/T1184.

7. Manatoko Papatahi
   Ina whakamatautauria te papatahi mā te whakamahi i ngā tikanga whakarara, mā te whakamahi rānei i ngā tikanga whatunga, me tutuki i te uara piki me te heke o te papa taumata hau te manawanui kua tohua.

8. Te Mahi Whakapūmau Kawenga

   • Me tutuki i te horahanga kawenga pokapū, te kaha kawenga kua whakatauria, me te piko e whakaaetia ana ngā whakaritenga kua tautuhia i roto i te Ripanga 3.

9. Ngā hapa o te mata
   Me kore he hapa nui o te mata mahi e pā kino ana ki te āhua, ki te mahi rānei, pērā i ngā kōhao onepu, ngā pūwero hau, ngā kapiti, ngā whakaurunga, ngā kōhao mimiti, ngā karawarawa, ngā pona, ngā tohu waikura rānei.

10. Ngā Kōhao me ngā Awaawa Miro
    Mō ngā wāhanga mīhini māpere, karāneti rānei o te Wāhanga 0 me te Wāhanga 1, ka taea te hoahoa i ngā kōhao miro, i ngā mokowā rānei ki te mata, engari kaua tō rātou tūranga e teitei ake i te mata mahi.

Whakamutunga

Me piri ngā wāhanga miihini o te māpere me te karāneti tino tika ki ngā paerewa hangarau tino pakari hei whakarite i te tika o te ine, te kaha ki te kawe kawenga, me te pumau mō te wā roa. Mā te whiriwhiri i ngā rauemi kounga teitei, te whakahaere i te kounga o te mata, me te whakakore i ngā hapa, ka taea e ngā kaihanga te tuku i ngā wāhanga pono e tutuki ai ngā tono tino pakari o ngā ahumahi mīhini tino tika me te tirotiro o te ao.
