I ngā wāhi whakaputa ahumahi, ko ngā paipa te "ora" mō te kawe rauemi. Heoi, i te aroaro o te pirau me te pakaru o ngā mea pakari pērā i te onepu, te paru, me ngā toenga para, he maha ngā wā ka pāngia ngā paipa noa e te turuturu me te pakaru i roto i te wā poto. Ehara i te mea me kati me te whakakapi noa i ngā wā katoa, engari ka tūpono pea he tūponotanga haumaru. I roto i ngā paipa maha e ātete ana ki te pakaru, kua noho ngā paipa ātete ki te pakaru o te silicon carbide hei taonga rongonui i roto i te ao ahumahi nā te mea he pai ake te ātete ki te pakaru. I tēnei rā, ka kōrero tātou mō tēnei "kaitākaro pakari" i roto i te umanga paipa.
He tokomaha te hunga kāore pea i te mōhio ki te rauemi silicon carbide. He mea ngāwari noa iho, he rauemi kore-whakarewa kore-waro, he rite tonu tōna pakeke ki te taimana, ā, he āhuatanga "ātete-hanga" tōna. He rite te paipa ātete-kakahu ki te whakatakoto i tētahi paparanga "pūeru taimana" ki runga i te paipa, ka taea te ātete ngāwari ki ngā pānga o ngā momo rauemi kakahu-kaha.
Ki te whakatauritea ki ngā paipa rino tuku iho me ngā paipa uku, ko ngā painga ongā paipa ātete-kākahu silicon carbidehe tino kitea. Tuatahi, he ātete tino pai ki te kakahu. Ahakoa te kawe i te paru kei roto te onepu quartz, te toenga para rānei me ngā matūriki mārō, ka taea e ia te pupuri i tōna āhua mata, ā, he roa ake te ora ratonga i ngā paipa maitai noa, ka whakaiti nui i te auau me te utu o te whakakapinga paipa. Tuarua, he kaha te ātete ki te waikura. He maha ngā wā kei roto i ngā rauemi ahumahi ngā wāhanga waikura pēnei i te waikawa me te kawakore, ā, he ngāwari ki te waikura me te koroheketanga ngā paipa noa. Heoi, he pumau ngā āhuatanga matū o te silicon carbide, ā, ka taea e ia te ātete ki te mimiti o ngā momo waikawa me te kawakore, kia pai ai mō ngā taiao mahi uaua ake.
Hei tāpiritanga, he āhuatanga ātaahua anō hoki ngā paipa ātete-kakahu silicon carbide – he pai te kawe wera, ka taea te tere te whakamarara i te wera i te wa e kawe ana i ngā rauemi pāmahana teitei, ka karo i te whakarerekētanga o te paipa i puta mai i ngā pāmahana teitei o te rohe, me te whakaiti i te ngaronga wera, ka whakaiti ā-kore i te whakapaunga pūngao whakaputa. Heoi anō, nā tōna hanganga kiato, kāore i te tino rerekē i ngā paipa noa ina tāutahia, me te kore e hiahiatia he whakarerekētanga taputapu tāpiri. He iti te uaua ki te tīmata, ā, ka taea te urutau ki ngā kaupapa hanga hou me ngā whakahoutanga paipa tawhito.
I ēnei rā, kua whānuitia te whakamahinga o ngā paipa ātete-kakahu silicon carbide i roto i ngā ahumahi maha pērā i te keri maina, te whakarewa, te hiko, me te miihini matū, pērā i te kawe paru i roto i ngā maina, ngā pūnaha desulfurization me te denitrification i roto i ngā tipu hiko, me te kawe para i roto i te ahumahi whakarewa, ka kitea ai ō rātou aroaro. Ehara i te mea ka whakaoti noa i ngā mamae o ngā paipa tuku iho e ngāwari ana ki te kakahu me te waikura, engari ka āwhina hoki i ngā umanga ki te whakaiti i te wā kore mahi, te whakaiti i ngā utu tiaki, me te whakapai ake i te pai o te whakaputa, ka noho hei "taputapu ātete-kakahu" nui i roto i te mara ahumahi.
I te whanaketanga tonu o te hangarau ahumahi, kei te whānui haere tonu te whakamahinga o ngā rauemi silicon carbide. E whakapono ana mātou ā muri ake nei, ka tukuna e ngā paipa ātete-mau silicon carbide te māramatanga me te wera ki ngā mara kua wehea, ka whakarato i te tiaki mō te mahi pumau o te whakaputa ahumahi.
