Ngā āhuatanga o te kohuke me te hanganga o te kohuke
Ko te kāneti he rōpū kohuke pamekaranete, he rite tonu ngā āhuatanga ā-tinana me ngā āhua tioata. Nō roto i te konumohe silicate (konupūmā), ā, e rua ngā wāhanga o te alumina me te konupūmā waikura i roto i te whakahaerenga kohuke. He nui te rerekētanga o te hanganga matū o te kāneti, ā, ko te tātai matū whānui ko A3B2 (SiO4) 3, ko A te tohu o te konupūmā takirua, te konupūmā, te rino, te manganese me ētahi atu kationa, ko b te tohu o te kationa pērā i te konumohe takirua, te rino, te chromium, te manganese. He rerekē te ingoa kotahi o te kāneti nā te rerekētanga o ngā takenga mai, ā, he rerekē ngā wāhanga matū o roto.
He rerekē te kātene i ngā matūriki tioata, he pakeke taurite, he teitei te ira rewa, he pakari pai, ā, he pumau matū hoki.
Mara tono me ngā tohu hangarau
He pakupaku te karaneti, he pai te pakari, he nui te kaha huri, he ōrite te rahi o te matūriki. He rauemi whakakoi taiao pai rawa atu i roto i te tirohanga, te hikohiko, te mīhini, te tā, te hanga whare, te taputapu, me te matawhenua whakarewa. Hei tāpiritanga, kua whakamahia hoki te karaneti i roto i ngā mara hangarau teitei pēnei i te whakapaipai, te matū hinu, te taiaho me te rorohiko.
He rerekē ngā whakaritenga kounga mō te karāneti i ngā whakamahinga rerekē, ā, ko ngā whakaritenga kounga mō ētahi whakamahinga nui o te karāneti e whai ake nei.
(1) Rauemi huri
Ko ngā mea whakakoi matatau e whakamahi ana i te hanga karāneti rino-konumohe, me iti iho i te 7.5 te pakeke, ā, he nui ake i te 93% te ihirangi karāneti, ka taea te whakaputa koki koi i roto i tētahi pēhanga, ā, e kore e pakaru hei paura, e ngaro ai te pai o te huri. E 75 ki te 80% o te ihirangi karāneti e hiahiatia ana mō te whakakoi pupuhi.
(2) Pāpāho tātari
Ko ngā whakaritenga whānui ko te karāneti rino-konumohe, te parakore o te 98% neke atu rānei, te whānuitanga o te rahi o te matūriki 0.25 ~ 5mm, te hanganga o te karāneti, kāore ngā matūriki e memeha, ka rewa i roto i te waikawa, he iti iho i te 2%, ā, me whai koki porowhita me koki te āhua o te kirikiri.
(3) Ngā Rauemi Kohatu
Me hiahia he tae karaka, he ma, he mārama, he rahi matūriki tioata, he whero, he papura, he kakariki, he rōhi te nuinga.
He teitei ake te māramatanga papura hohonu, ā, he nui ake te pakeke i te 7, neke atu rānei
(4) Ngā whāriki o te karaka me ngā taputapu tika
Me whai parakore o te karāneti, he pai te whakatioatatanga, he pakeke teitei, he pai te ātete wera.
Hangarau Tukatuka
Hei whakatutuki i ngā whakaritenga o te parakore o te karāneti, te rahi o te matūriki me te tohatoha i roto i te tono, me mahi te tukatuka o te purenga kohuke, te mira pai, te mira tino pai, me te whakarōpūtanga pai.
Kua whakamahia ngā tono, te whakapūmau, te kōwhiringa aukume, me ngā tikanga whakakohuke matū i roto i te purenga whakakohuke o te karāneti.
Ko te whiriwhiringa anō te nuinga e whakamahia ana hei tango i te kohuke longtezed, mika, flash, bridal, me te quartz rite, ā, ko ngā taputapu whiriwhiringa anō e whakamahia ana ko te wiri, te jig, te chute, me te mīhini keri re-prime. Ko te mahi matua o te whakapūngā ko te tāpiri i te wehenga rongoā o te quartz, te sericite, te tungsite mā, te siliconline, me ētahi atu.
Ko te kōwhiringa aukume te nuinga e whakamahia ana hei tango i ngā kohuke aukume, pērā i te aukumeiti, te konganuku rino titanium, te waikura rino me te iti o te kōhatu roa, te kuata, te siliconline, me ētahi atu. Ko te mīhini tohatoha aukume rango matua, te mīhini wehenga aukume pereti, te mīhini wehewehe aukume mowhiti teitei.
Ko te whakakoi matū he mea tukatuka waikawa te nuinga, ā, he mea whakaoho hei tango atu i ngā kohuke kei roto te rino mā te rumakina ki roto i te kukū porrontal. Ko te whiriwhiri i ngā tikanga whakakoi motuhake me ngā rere o ngā tukanga e hangai ana ki ngā momo kohuke, te kāneti, te kōhatu pupuhi me ngā kohuke e haere tahi ana. Ko te nuinga o ngā mahi whakaputa ahumahi e whakamahi ana i te tukanga tohatoha tahi.
Hei whakaputa i ngā mea whakakoi witi pai rawa atu me ngā mea whakakoi witi tino pai rawa atu, ka mahi anō te kukū karāneti i te mira pai rawa atu, te mira tino pai rawa atu me te maimoatanga matū.
Ka whakamahia e te mira pai me te mira tino pai te huri wiri, te mira pōro me te kakahu whakaoho. Ka whakamahia e te horoinga matū te horoinga waikawa hauwai ahumahi, te rumaki waikawa me te horoi wai, ka whakatauhia te paura kukū galline ki te wai, ā, ka tohua te whakarōpūtanga kia rite ki te rahi o te matūriki, ā, i te mutunga, 45 ki te 0.5 mm (tau) te whakakoi.
