I ngā kokonga o ngā awheawhe wheketere me te kawe maina, he "tūranga" nui engari e warewarehia ana - ko te paipa kawe. Ka kawe rātou i ngā kohuke, i te moata, me ngā rauemi mata matū i ia rā, i ia rā, ā, ka pāngia tonutia ō rātou pakitara o roto e te waku me te pānga mai i ngā rauemi. I roto i te wā, ka ngāwari ki te pakaru me te haehae, te turuturu, e kore e pā noa ki te whakaputa engari me utu nui hoki te tiaki me te whakakapinga. Ko te arai paipa ātete-kakahu silicon carbide ka kōrerohia e tātou i tēnei rā he rite ki te whakatakoto i tētahi paparanga o te "pūeru maitai kore e kitea" ki runga i ngā paipa noa, e whakaoti marie ana i tēnei raruraru nui.
Tērā pea ka pātai tetahi, he aha te meakarāhe silicon? Ina hoki, ehara i te mea ngaro. Ko te tikanga, he rauemi hangai i hangaia mai i te waro me te silicon, he rite te pakeke ki te taimana.
Ki te whakaritea ki te pakitara o roto o ngā paipa noa, he maha ngā wā ka nui ake te pakeke o te arai silicon carbide. Ina pāngia te pakitara o roto e ngā matūriki koi me te moata tere-rere, ka taea e te silicon carbide te mahi hei whakangungu rakau hei ārai i te waku me te ārai i ngā karawarawa, i ngā pakaru rānei. Ahakoa mō te kawe roa i ngā rauemi e kaha ana te pakaru, ka taea e tōna pakitara o roto te noho papatahi me te maeneene, me te kore e matotoru, e pakarukaru rānei nā te pakaru, ka roa ake te ora o te paipa.
Haunga te ātete ki te kakahu, he pūkenga huna anō hoki tōna – 'ka taea te tu atu ki te hanganga'. I roto i te whakaputanga ahumahi, ko ngā rauemi e haria ana ehara i te mea he "hurihuri" noa iho, engari ka taea hoki te kawe i ngā pāmahana teitei me te waikura waikawa-pūtake. Hei tauira, i roto i te mara o te miihini matū, he kaha te waikura o ētahi rauemi, ā, he ngawari te waikura me te tihore i te arai o ngā paipa noa; I roto i te umanga whakarewa, ka taea e ngā rauemi pāmahana teitei te whakapōturi me te pakaru o te arai. Ka taea e te arai silicon carbide te tu atu i ngā pāmahana o te rau nekehanga Celsius me te ātete ki te mimiti o te nuinga o ngā rauemi waikawa me te kawakore, me te pupuri i te mahi pumau i roto i tētahi "taiao uaua".
Mō ngā umanga, he tino kitea ngā painga o tēnei arai iti: kāore e hiahiatia kia kati pinepine, kia whakakapia hoki ngā paipa, kia whakaitihia ai ngā mate i puta mai i ngā aukati whakaputa; Kāore e hiahiatia kia haumi tonu ki ngā utu tiaki, ka taea te penapena moni nui i te wā roa; Ko te mea nui ake, ka taea te whakarite kia maeneene te kawe rauemi me te karo i ngā tūponotanga haumaru me ngā raruraru taiao i puta mai i te turuturu o ngā paipa.
Mai i ngā hononga paipa ngaro ki te "taputapu ātete-kakahu" e tiaki ana i te hanga ahumahi, ko te uara o te arai paipa ātete-kakahu silicon carbide kei roto i tōna kaha ki te "whakaoti rapanga nui i roto i ngā taipitopito iti". Mō ngā umanga e whai ana i te hanga pai me te pumau, ko te whiriwhiri i tēnei mea ehara i te mea he whakapai ake i ngā taputapu anake, engari he whakaaro roa hoki mō te pai o te hanga me te whakahaere utu.
