I te hononga o te hanga ahumahi me te whakahaere taiao, kei reira tonu ētahi wāhanga te āhua nei kāore i te tino whai hua, e whakahaere puku ana i ngā kaupapa matua.Ngā pūwero whakakorenga whanariki silicon carbideko rātou ngā "kaitiaki ngaro" e tiaki ana i te taiao āhuarangi i roto i ngā āhuatanga ahumahi pēnei i ngā tipu hiko me ngā mira maitai. Ahakoa tōna rahi iti, kua noho hei wāhanga matua e kore e taea te whakakapi i ngā pūnaha whakakorenga whanariki nā ōna rauemi me tōna hoahoa ahurei.
Ko te tango whanariki, i roto i ngā kupu māmā noa iho, e pā ana ki te tango i ngā whanariki mai i te hau para ahumahi me te whakaiti i te parahanga taiao pēnei i te ua waikawa. Hei "kaiwhakahaere" o te pūnaha tango whanariki, ko te pūwero te kawenga mō te whakakorikori ōrite i te paru tango whanariki me te rehu ki roto i te hau putanga, kia taea ai e te paru te pa atu me te tauhohe ki ngā whanariki, kia tutuki ai te whāinga o te purenga o te hau putanga. Me tūpato te pūwero i ngā pāmahana teitei me ngā taiao mahi tino waikura, engari me whakarite hoki i ngā pānga whakakorikori pumau kia pai ake ai te pai o te tango whanariki.
Ko te putanga mai o te rauemi silicon carbide e tino tutuki ana i ēnei whakaritenga uaua. Ko te silicon carbide he rauemi kore-whakarewa kore-waro i hangaia i roto i te hangai e whakakotahi ana i ngā āhuatanga ā-tinana o te kaha me te pakeke teitei, me te ātete pai ki te pāmahana teitei me te waikura. Ahakoa te mimiti matū o te paru me te tunu pāmahana teitei o te hau putanga i te wā o te tukanga whakakorenga whanariki, ka taea e te pūwero silicon carbide te pupuri i te pumau hanganga mo te wa roa, ā, kāore e ngawari te pakaru, te whakapē, te pakaru rānei, ka tino whakaiti i te auau o te whakakapinga taputapu me ngā utu tiaki.
Ki te whakatauritea ki ngā pūwero whakarewa, uku rānei tuku iho, he tino kitea ngā painga o ngā pūwero whakakorenga whanariki silicon carbide. He maeneene tōna pakitara o roto, kāore e ngāwari ki te tauine me te aukati, ā, ka taea tonu te whakarite kia maeneene te rehu me te atomization ōrite o te paru, kia tino oti ai te tauhohenga whakakorenga whanariki. I taua wā anō, he pai te kawe wera o te rauemi silicon carbide, ā, ka taea te urutau tere ki ngā huringa pāmahana i roto i te taiao mahi, ka karo i te kino i puta mai i te whakawhānui me te whakaheke wera, me te whakaroa i tōna roanga mahi. Mā ēnei āhuatanga ka taea e ngā pūwero silicon carbide te whakaatu i te pono me te whai huatanga kaha ake i roto i ngā āhuatanga ahumahi uaua.
I ēnei rā, me te whakapai tonu i ngā whakaritenga tiaki taiao, kei te piki haere te kaha o ngā whakaritenga mahi a ngā umanga ahumahi mō ngā taputapu whakakorenga whanariki. Kua waiho ngā pūwero whakakorenga whanariki silicon carbide hei whiringa nui mā te maha o ngā umanga ki te whakapai ake i ā rātou pūnaha whakakorenga whanariki nā te mea he tino pai te mahi whānui. Ka whakamahia e ia ngā rauemi "mārō" hei hanga i tētahi raina parenga taiao kaha, ā, ka āwhina i ngā umanga ki te whakatutuki i te whakaputa matomato me te mahi pumau. He mahi nui tāna ki te whakatairanga i te whanaketanga ahumahi pumau.
He nui te kawenga taiao o te pūwero iti. Ko te whakamahinga whānui o ngā pūwero whakakore hauwai silicon carbide ehara i te mea he ahunga whakamua noa iho i roto i te hangarau hanga ahumahi, engari he whakaaturanga ora hoki o te whakapau kaha o ngā umanga ki te tiaki taiao. I te heke mai, me te auahatanga tonu o te hangarau rauemi, e whakapono ana mātou ka tiaho ake ngā pūwero silicon carbide i roto i te mara o te tiaki taiao, ā, ka kaha ake te tautoko i te tiaki i ngā rangi kikorangi me ngā kapua mā.
