I roto i te tukanga tiaki taiao o te whakaputanga ahumahi, he taahiraa nui te tango-pūngao hei tiaki i te rangi kikorangi, ā, ko te pūngao, hei "wāhanga matua" o te pūnaha tango-pūngao, ka whakatau tika i te whai huatanga o te tango-pūngao me te roa o te ora o ngā taputapu. I ngā tau tata nei,ngā pūwero whakakore pūhā i hangaia ki te silicon carbidekua noho haere ngā rauemi hei whiringa matua i roto i te umanga. He aha te mea e tū motuhake ai tēnei rauemi "ngaio"?
Ina hoki, ehara te silicon carbide i te "rauemi hou". He rauemi kore-whakarewa kore-waro i hangaia i roto i te hanga, ā, ko tōna āhuatanga nui ko tōna "mana mārō" - he nui ake te ātete ki te pāmahana teitei, te ātete ki te waikura, me te ātete ki te kakahu i ngā pūwero whakarewa tuku iho, kirihou rānei. I te wā o te tukanga whakakorenga whanariki, he maha ngā wā ka kaha te waikura o te paru i rehuhia, ā, kāore i te iti te pāmahana. Ka pāngia wawetia ngā pūwero noa e ngā raruraru pēnei i te kakahu, te waikura, me te aukati, e kore e pā noa ki te pānga whakakorenga whanariki engari me whakakapi pinepine, ka piki ake te utu o te umanga. Ka taea e ngā pūwero silicon carbide te aro atu ki ēnei taiao uaua, ahakoa ka roa te wā e pāngia ana e ngā paru waikura, ka taea e rātou te pupuri i te pumau o te hanganga, kāore e ngāwari te whakapē, te aukati rānei, ā, ka tino whakaiti i te auau tiaki.
Haunga te pakari, he tino pai te kaha mahi a te pūwero silicon carbide. He rite tonu tōna hoahoa hanganga ki ngā whakaritenga o te rehu tango-pūngoi, e āhei ai te paru ki te hanga i ngā pata rite, kia rite, kia pai hoki te pa atu ki te hau paru, kia tino mārama ake ai te tauhohenga tango-pūngoi. Heoi anō, he māmā te silicon carbide, he kaha, he ngāwari ake te tāuta, me te kore e tāpiri atu ki te pūnaha tango-pūngoi.
Tērā pea ētahi e whakaaro ana "he tino utu nui ngā rauemi motuhake", engari i te wā roa, he nui ake te whai huatanga o ngā pūwero silicon carbide. He maha ngā wā e roa ake ai tōna ora mahi i ērā o ngā pūwero tuku iho, ka whakaiti i ngā utu whakakapinga me te wā tiaki mō te wā kore mahi, ka penapena ā-kore i ngā whakapaunga mō ngā umanga, me te whakarite hoki i te pai o te tango-pūwero me te āwhina i ngā umanga ki te aro atu ki ngā aromatawai taiao.
I ēnei rā, kei te kaha haere ngā whakaritenga tiaki taiao, ā, ka nui ake te aro o ngā kamupene ki te "whai hua, te roa, me te rangimarie o te hinengaro" i te wā e whiriwhiri ana i ngā taputapu tiaki taiao. Ko ngā pūwero whakakorenga haukini kapia te mea e pai ake ana ki te taiao mō ngā umanga ahumahi nā ō rātou painga rauemi. Ko tēnei 'wāhanga hangarau mārō' e huna ana i roto i te pūnaha whakakorenga haukini e tiaki ana i te taurite i waenga i te hanga ahumahi me te rangi kikorangi me ngā kapua mā me tōna kaha, ā, e whakarato ana i te tautoko pono mō te whanaketanga matomato o ngā umanga.
