I ngā wāhi wehewehe totoka-wai i roto i ngā ahumahi pēnei i te keri maina, te matū, me te tiaki taiao, ka kitea tonutia te aroaro o ngā porowhita silicon carbide. He rite ki te "mīhini tātari" whai hua ka taea te wehewehe tere i ngā matūriki totoka mai i ngā wai i roto i te ranunga, ā, ko te uho o te whakatutuki i tēnei wehenga tika kāore e taea te wehewehe me te kore he wāhanga e ngaro wawetia ana - te paipa waipuke.
He tokomaha te iwi, i te kitenga tuatahi i tētahite porowini karawiti silicon,ka aro nui ki te rango matua pakari, engari ka wareware ki te "ngongo angiangi" e toro atu ana mai i runga. Engari i roto i te meka, ko te paipa waipuke te "kaiārahi" o te pūnaha wehenga katoa, ā, ko tōna hoahoa me tōna āhua te mea e whakatau tika ana i te kounga o te pānga wehenga.
Mai i te tirohanga o te kaupapa mahi, ka whakawhirinaki te porowhita silicon carbide ki te kaha porotītaha i hangaia e te hurihanga tere-teitei hei whakatutuki i te wehenga: i muri i te urunga mai o te wai whakaranu mai i te putanga whāngai, ka huri tere ki roto i te rango, ā, ka whiua ngā matūriki totoka he nui te kiato ki te pakitara rango ka tukuna i te putanga rere o raro; Ka huihui ngā wai iti te kiato (ngā matūriki iti rānei) ki waenganui o te hurihanga, ka hanga he "pou hau" ka rere i roto i te paipa waipuke i te tihi. I tēnei wā, ka kitea te tūranga o te paipa waipuke - ehara i te mea he putanga noa iho mō ngā "matū wāhanga māmā", engari ka whakau hoki i te mara rere i roto i te porowhita katoa mā te whakahaere i te tere rere me te pēhanga.
He aha te take e tika ai te whakamahi i te rauemi silicon carbide hei hanga paipa waipuke? He hononga tata tēnei ki tōna taiao mahi. I te wā o te tukanga wehenga, he maha ngā matūriki iti kei roto i te wai e rere ana i roto i te paipa waipuke, ā, mā te horoi roa ka pakaru te paipa; I taua wā anō, he āhuatanga waikawa, he āhuatanga kawakore rānei ō ētahi rauemi ahumahi, ā, he ngāwari te waikura o ngā paipa whakarewa noa. Ka whakaoti tika te rauemi silicon carbide i ēnei raruraru nui e rua: ko tōna pakeke te tuarua o te taimana, ko tōna ātete kakahu he maha ngā wā i te maitai noa, ā, ka taea e ia te tū atu ki te horo o ngā matūriki mō te wā roa; I taua wā anō, he tino kaha tōna ātete ki te waikura waikawa me te kawakore, ā, ka taea te pupuri i te mahi pumau ahakoa i raro i te pāmahana teitei me ngā āhuatanga waikura kaha, ka roa ake te roa o te ora o te taputapu.
Tērā pea ka pātai tetahi: Mēnā kāore te paipa waipuke i pakaru, kāore he take kia tiakina? Kāore rawa. Ka pāngia hoki te tika o te tāutanga o te paipa waipuke ki te pānga wehenga. Hei tauira, ki te papaku rawa te hohonutanga o te paipa waipuke e whakaurua ana ki te tinana matua o te awhiowhio, ka taea e ia te kawe hē i ētahi matūriki taratara ki roto i te wai waipuke, ka hua ake he "rere taratara"; ki te whakaurua ki te hohonu rawa, ka piki ake te ātete o te rere o te wai, ka whakaiti i te pai o te wehenga. Hei tāpiri, ki te nui rawa ngā poke e piri ana ki te pakitara o roto o te paipa waipuke i te wā e whakamahia ana i ia rā, ka whakawhāitihia te awa rere, ā, ka pāngia hoki te tere rere me te tika o te wehenga. Nō reira, he mea nui te horoi me te tirotiro auau.
I ēnei rā, me te pikinga ake o te hiahia mō te whai huatanga o te wehenga me te tiaki taiao i roto i te umanga, kei te arotau tonuhia te hoahoa o ngā paipa waipuke silicon carbide. Hei tauira, mā te whakarerekē i te āhua o te waha o te paipa me te arotau i te rahi o te diameter o roto, ka whakaitihia te ātete wai; ka mahi hoki ētahi kaihanga i te maimoatanga whakakanapa motuhake ki te waha o te paipa hei whakaiti i te piri o te poke me te whakapai ake i te pumau me te whai hua o te tukanga wehenga.
He paipa pupū silicon carbide ngāwari noa iho e huna ana i te whakakotahitanga mohio o te pūtaiao rauemi me te miihini wai i muri i a ia. Ka mau ki a ia te "kawenga nui" me tōna "tinana iti", ka noho hei hononga matua ki te whakarite i te mahi pumau o ngā awhiowhio silicon carbide me te whakapai ake i te kounga wehenga. I te heke mai, me te haere tonu o te whanaketanga o te hangarau rauemi silicon carbide, ka whai wāhi nui tēnei 'rangatira matua' ki ngā mara maha atu, ka whai wāhi ki te whanaketanga whai hua me te matomato o te whakaputanga ahumahi.
