Ko te poroporo mānu he momo pōro pungarehu rere ka taea te mānu i runga i te mata o te wai. He hina mā, he angiangi, he tuwhera te pakitara, he tino māmā te taumaha, ko te taumaha kotahi he 720kg/m3 (taumaha) me te 418.8kg/m3 (māmā), ko te rahi o te matūriki he 0.1mm te rahi, he kati, he maeneene te mata, he iti te kawe wera, ā, he ātete ahi ≥ 1610 ℃. He mea ātete wera pai rawa atu, e whakamahia whānuitia ana i roto i te hanga i ngā mea whakarewa māmā me te keri hinu. Ko te hanganga matū o te poroporo mānu ko te hauhā silicon me te waikura konumohe te nuinga. He maha ngā āhuatanga, pērā i ngā matūriki angiangi, he tuwhera, he māmā, he kaha teitei, he ātete kakahu, he ātete pāmahana teitei, he whakamarumaru wera, he whakamarumaru me te ātete mura. Ko tētahi o ngā rauemi mata e whakamahia whānuitia ana i roto i te umanga ātete ahi.

Kupu Whakataki

He tino pai te mahi me te tono o ngā piripiri mānu

He ātete ahi teitei. Ko ngā matū matua o te pirepire mānu ko te silicon me ngā waikura konumohe, ko te hauhā silicon he tata ki te 48-66%, ā, ko te waikura konumohe he tata ki te 26-36%. Nā te mea ko te ira rewa o te hauhā silicon he 1720 ℃, ā, ko te waikura konumohe he 2060 ℃, he ātete wera teitei ēnei e rua. Nō reira, he tino ātete ahi te pirepire mānu, e tae ana ki te 1620-1800 ℃, ā, he ātete wera tino pai. He mama, he ārai wera. He angiangi, he takoto kau te pakitara o te pirepire mānu, ā, he haurua-kore te kōhao. He iti noa te hau (N2, H2, CO2, me ētahi atu), ā, he tino puhoi te kawe wera. Nō reira, ehara i te mea he mama noa ngā pirepire mānu (250-450 kg/m3). Ko te rahi matūriki tūturu o ngā pirepire mānu he 1-250 maikorona. Ka taea te whakamahi tika i ngā pirepire mānu me te kore e huri. Ka taea e te pai te whakatutuki i ngā hiahia o ngā momo hua. Ko ētahi atu rauemi whakamahana mama he nui te rahi o te matūriki (pērā i te perlite). Mēnā ka hurihia, ka nui ake te kaha, ā, ka tino whakaitihia te whakamahana. Mō tēnei, he painga ngā pīrere rere. He pai te whakamahana hiko. Ko te pīrere rere i muri i te whiriwhiringa o te pīrere aukume he rauemi whakamahana he tino pai te mahi, ā, kāore e kawe hiko. I te nuinga o te wā, ka heke te ātete o ngā mea whakamahana i te pikinga o te pāmahana, engari ka piki ake te ātete o ngā pīrere rere i te pikinga o te pāmahana. Kāore tēnei painga i ngā rauemi whakamahana kē atu. Nō reira, ka taea te whakamahi hei hanga hua whakamahana i raro i ngā āhuatanga pāmahana teitei.
