Ko te kaupapa matua o te tango i te puehu o te pūwero ko te wehe i ngā matūriki puehu mai i te hau, i te paowa rānei.
Tuatahi, ka whakamakukuhia ngā matūriki puehu ki te wai hei whakanui ake i te rahi me te taumaha motuhake o te matūriki. Kātahi ka wehea ngā matūriki puehu mai i te hau, i te hau paru rānei. Ina pakaru te pūwero whakakore pūhā, me tango te pūwero ki raro. Ko te mahi motuhake koia tēnei:
1) Me pupuri tika ngā wāhanga e toe ana, ngā wāhanga tāpiri rānei: He takai me ngā tapanga motuhake ā ngā kaiwhakarato whānui, arā, me waiho kia kore e whakamahia. Me rumakina ngā pūwero tango whanariki kua tangohia ki te hinu (penehīni, hinu tīhiera, me ētahi atu) hei ārai i te waikura.
2) Mēnā he hapa kei te whakamahia mō te pūwero whakakore hauwai, me tirotirohia te pūwero. Me whakamahi ngā kaiwhakamahi i ngā taputapu motuhake, i ngā taputapu tika rānei hei wetewete me te whakawehe i te hononga huihuinga i ia taahiraa.
3) Me tāuta tonu ngā pūwero kua tangohia ki runga i te papa whakamātautau pūwero, kaua ki te whakamahi i tētahi maimoatanga. E ai ki te pēhanga mahi kua whakaritea, ka mahia ngā āhuatanga rere, te kimi koki rehu me te tirotiro i te kounga rehu. Ka taea tēnei te whakatau i te wā e rapu raruraru ana.
Kua puta te pūwero whakakore-whanariki i raro i ngā whakaritenga tiaki taiao. Ko te kaupapa matua o te hua he tango i te hau me ērā atu mea. Mā tēnei ka pai ake te taiao mō te hanga ahumahi. Kei raro nei ngā āhuatanga matū o te pūwero whakakore-whanariki, ā, e tino hiahia ana mātou ki te āwhina i a koe.
Te ātete waikura o ngā pūwero whakakore pūhā
Ina werahia te rauemi silicon carbide ki te 1300 nekehanga i te hau, ka hangaia he paparanga tiaki silicon dioxide ki runga i te mata o te tioata silicon carbide. Mā te matotoru o te paparanga tiaki ka ārai i te haere tonu o te waikura o roto o te silicon carbide. Mā tēnei ka pai te ātete o te silicon carbide ki te waikura. Ina neke ake te pāmahana i te 1900K (1627 C), ka pakaru te kiriata tiaki silica. I tēnei wā, ka nui ake te waikura o te silicon carbide. Nō reira, ko te 1900K te pāmahana mahi teitei rawa atu o te silicon carbide i roto i te hau waikura.
Te ātete waikawa me te kawakore o ngā pūwero whakakore pūngāwerewere:
I roto i te āhuatanga o te ātete waikawa, te ātete kawakore me te waikura, ka taea e te mahi a te kiriata tiaki silicon dioxide te whakarei ake i te ātete waikawa me te ātete kawakore o te silicon carbide.
