I roto i te mara o te ine tika, ko te whiriwhiri i ngā taputapu ine kounga teitei ka pā tika ki te tika o te whakaputanga ahumahi me te whakamātautau taiwhanga. Hei taputapu matua mō te kimi poutū, kua noho te rūri tapawhā karāhe hei wāhanga nui o te hanga tika me tōna pumau me te tino tika. Ka whakamāramahia e tēnei tuhinga tōna whakamāramatanga, āna whakamahinga, ōna āhuatanga rauemi me ngā horopaki tono, hei āwhina i ngā kaihanga ine tika kia mārama katoa ki tēnei taputapu nui.
1. He aha te Rūri Tapawhā Granite?
Ko te rūri tapawhā karāhe, e mōhiotia ana ko te rūri koki-matau karāhe, ko te aratohu koki-matau tika rānei i ētahi horopaki ahumahi, he taputapu ine tika ngaio i hangaia mō te kimi i te poutū o ngā wahi mahi me te tūranga poutū whanaunga i waenga i ngā wāhanga. Haunga tōna mahi matua o te kimi poutū, he taputapu tohutoro pono hoki mō te tohu me te whakanoho i te wā e mahi ana te mīhini.
Ko te hanganga matua o te rūri tapawhā karāneti ko te pyroxene, te plagioclase, te iti o te olivine, te biotite me te micro-magnetite, e homai ana he āhua pango matotoru me te hanganga ā-roto pakari. Ko te mea e motuhake ai tēnei rauemi ko te mea kua pāngia e te koroheketanga me te whakatiotanga taiao mō ngā rau miriona tau. Mā tēnei tukanga taiao roa ka whakarite kia tino ōrite te kakano o te karāneti, kia tino pumau te āhua, kia kaha te kaha miihini me te pakari o te mata. Ahakoa i raro i ngā āhuatanga mahi taumaha i roto i ngā taiao ahumahi, ka taea tonu e ia te pupuri i tōna tino tika taketake me te kore e kitea he rerekētanga, kia whānuitia ai te whakamahi i roto i ngā wāhi whakaputa ahumahi me ngā horopaki ine taiwhanga tino tika.
2. He aha ngā Whakamahinga o ngā Rūri Tapawhā Granite?
He taputapu tino tika ngā rūri tapawhā karāhe, he mea nui hoki ki ngā hononga maha o te umanga hanga tino tika, ā, e whai ake nei ngā whakamahinga matua:
- Te Kimi me te Ine: Hei tohutoro paerewa mō te kimi i te poutū, ka whakamahia hei manatoko i te tika o te poutū o ngā wāhanga matua o ngā taputapu mīhini, ngā taputapu mīhini me ngā wāhanga mahi tino tika. Ka taea e ia te tautuhi whai hua i ngā pekapeka i te ahunga poutū, kia mōhio ai kei te tutuki ngā wāhanga tukatuka i ngā whakaritenga tika hoahoa.
- Te Tohu me te Tūnga: I roto i te tukanga mīhini me te huihuinga, ka whakaratohia he tohutoro koki-matau tika mō te tohu i ngā rārangi me te tūnga o ngā wahi mahi. Mā tēnei ka āwhina i te whakarite i te ōritetanga o te tūnga mīhini o ia wāhanga, ka whakaiti i ngā hapa i puta mai i te tūnga hē.
- Te Tāutanga Taputapu me te Hanganga Hangarau Ahumahi: I te wā e tāuta ana i ngā taputapu mīhini tino tika, ngā raina whakaputa aunoa me ētahi atu taputapu, ka whakamahia hei whakatika i te poutū o te turanga taputapu me ngā wāhanga, kia mau ai te mahi a ngā taputapu me te whakapai ake i te tika o te whakaputanga whānui. I roto i ngā kaupapa hangarau ahumahi e hiahia ana ki te poutū teitei, pērā i te tāutanga o ngā anga mīhini me ngā paipa tino tika, he taputapu nui hoki hei kimi me te whakatika.
I roto i te umanga mīhini, e mōhiotia ana he taputapu ine nui mō te kimi poutū, te tāutanga, te whakanoho mīhini me te tohu i ngā taputapu mīhini, ngā taputapu mīhini me ō rātou wāhanga. Ki te whakatauritea ki ngā rūri koki matau whakarewa tuku iho, he nui ngā painga o ngā rūri tapawhā karāhe pērā i te tika ake, te pumau mō te wā roa, me te tiaki ngāwari. Kāore he take mō te maimoatanga ārai-waikura auau, ā, he uaua te pakaru o te mata, ka tino whakaiti i te utu tiaki i muri mai.
3. He aha te rauemi o ngā rūri tapawhā karāhe?
Ko te nuinga o ngā rauemi mō ngā rūri tapawhā karāhe kounga teitei he mea whiriwhiri mai i te karāhe tūturu kounga teitei, ā, ko te karāhe rongonui "Jinan Green" (he momo karāhe kounga teitei nō Jinan, Haina, e mōhiotia ana mō ōna āhuatanga ā-tinana pai rawa atu) te rauemi mata e pai ana. Whai muri i te whiriwhiringa rauemi tino pakari, ka pāngia te karāhe e ngā tukanga tukatuka matatau, tae atu ki te tapahi miihini, te huri me te whakakanapa ā-ringa, hei hanga i te hua rūri tapawhā karāhe whakamutunga.
Ko ngā āhuatanga tino pai o te rauemi e whai ake nei:
- He Hanganga Kohuke Pai Rawa: Ko ngā kohuke matua ko te pyroxene me te plagioclase, ā, he iti noa te olivine, te biotite me te micro-magnetite hei tāpiri. Ka hangaia e tēnei hanganga he hanganga ā-roto matotoru, ōrite hoki, koinei te pūtake o tōna pakeketanga me tōna pumautanga.
- Ngā Painga o te Pakaritanga Taiao: Whai muri i ngā rau miriona tau o te whanaketanga whenua taiao, kua tukuna katoatia te ahotea o roto o te karāhe, ā, kua tino ōrite te kakano. Mā tēnei ka whakakorea te mōrearea o te whakarerekētanga o roto i puta mai i te ahotea toenga, kia mau ai te pumau o te āhua o te hua mō te wā roa.
- Ngā Āhuatanga Tinana Pai Rawa: He kaha ā-ringa teitei, he pakeke hoki te mata (e eke ana ki te taumata pakeke Mohs 6-7), ā, ka taea te ātete ki te pānga me te kakahu i te wā e whakamahia ana. I taua wā anō, he pai te pumau o te pāmahana, ā, he iti iho te tauwehenga whānui wera i ērā o ngā rauemi whakarewa, nō reira kāore e ngāwari te pāngia o te tika e te huringa o te pāmahana taiao.
- He Ātete Pai ki te Waikura me te Kore-Aukumetanga: He ātete te rauemi ki te waikura, te waikawa me te kawakore, ā, ka taea te whakamahi i roto i ngā taiao ahumahi uaua pēnei i ngā awheawhe me ētahi āhuarangi matū me te kore e waikura. Hei tāpiri, he kore-aukumetanga, e karo ana i te pokanoa o te kaha aukume ki te ine tika, kia pai ake ai mō te kimi i ngā wahi mahi tairongo-aukume me ngā taputapu tika.
4. He aha ngā āhuatanga whakamahi mō ngā rūri tapawhā karāhe?
He whānuitia te whakamahinga o ngā rūri tapawhā karāhe i roto i ngā āhuatanga maha e hiahia ana kia ine tika te ine me te tohutoro i te poutū, ā, he tino rite tonu ō rātou āhuatanga tono ki ngā paerewa me ngā hiahia tuturu o te umanga ine tika:
- Te Whakatutuki i ngā Paerewa Tika: E tino tutuki ana i te paerewa tika papatahi GB/T 6092-2009 me te paerewa tika poutū GB/T 6092-2009 (te putanga whakahou o te GB 6092-85 taketake), me te whakarite kia tutuki tōna tika i ngā paerewa ine matatau o te ao me te motu. Nā tēnei ka waiho hei taputapu pono mō ngā umanga ki te mahi i te kimi tika i runga anō i ngā paerewa ahumahi.
- Te Whakapai Ake i te Hanganga mō te Whakamahinga Whaihua: Hei whakapai ake i te ngāwari o te whakamahi, he maha ngā hua rūri tapawhā karāhe kua hangaia me ngā kōhao whakaiti taumaha. Ehara i te mea ka whakaitihia e ēnei kōhao te taumaha katoa o te rūri, ka māmā ake te kawe me te whakahaere mā ngā kaiwhakahaere, engari kāore hoki e pā ki te pumau o te hanganga me te tika o te ine o te hua. I taua wā anō, ko te ātete taha o te rūri tapawhā karāhe paerewa ka whakahaerehia i roto i te 0.02mm, e whakarite ana i te tino tika o te mata tohutoro taha.
- Te Urutau ki ngā Taiao Mahi Kanorau: Ka taea e ia te pupuri i te tino tika i raro i ngā āhuatanga taumaha (pēnei i te wā e whakamahia ana hei tohutoro mō te whakatakotoranga o ngā mea mahi taumaha) me ngā taiao pāmahana whānui (ko te awhe pāmahana he -20℃ ki te 40℃). Nā tēnei urutau ka pai mō ngā momo wāhi ahumahi, tae atu ki ngā awheawhe taputapu mīhini, ngā whare hanga wāhanga motuka, ngā awheawhe tukatuka wāhanga rererangi, tae atu ki ngā taiwhanga tino tika pēnei i ngā taiwhanga ine me ngā pokapū tirotiro kounga.
- Ngā Āpure Matua mō te Whakamahinga: I roto i te umanga hanga motuka, ka whakamahia hei kimi i te tūnga poutū o ngā poraka rango miihini me ngā wāhanga tuku; i roto i te umanga rererangi, ka whakamahia hei kimi tika i ngā wāhanga hanganga rererangi me ngā wāhanga miihini; i roto i te umanga hanga taputapu hiko, ka āwhina ki te whakarite i te tūnga poutū o ngā papa ara iahiko me te tāutanga wāhanga. Hei tāpiri, ka whakamahia whānuitia hoki i roto i te tiaki me te whakatikatika i ngā taputapu tika, hei tohutoro paerewa mō te whakatikatika i ētahi atu taputapu ine.
