Ko te pīrere rere he momo pōro pungarehu rere ka taea te mānu i runga i te mata o te wai. He hina mā te tae, he angiangi, he takoto kau ngā pakitara, ā, he tino māmā. Ko te taumaha kotahi ko 720kg/m3 (taumaha), 418.8kg/m3 (māmā), ā, ko te rahi o te matūriki he tata ki te 0.1mm. He kati, he maeneene te mata, he iti te kawe wera me te ātete ahi o ≥ 1610 ℃. He rauemi 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 pīrere rere ko te hauhā silicon me te waikura konumohe. He āhuatanga o ngā matūriki angiangi, takoto kau, māmā, kaha teitei, ātete kakahu, ātete pāmahana teitei, whakamarumaru wera, whakamarumaru me te ātete mura. Ko tētahi o ngā rauemi mata e whakamahia whānuitia ana i roto i te umanga ātete ahi.

He tino pai te mahi me te whakamahinga o ngā pīrere mānu

He ātete ahi nui. Ko ngā matū matua o ngā pirepire e mānu ana ko ngā waikura o te silicon me te konumohe, ko te hauhā silicon te 50-65%, ā, ko te hauhā konumohe te 25-35%. Nā te mea he teitei te pāmahana rewa o te hauhā silicon ki te 1725 nekehanga Celsius, ā, ko te pāmahana rewa o te waikura konumohe he 2050 nekehanga Celsius, he matū ātete ahi nui ēnei e rua. Nō reira, he tino teitei te ātete ahi o ngā pirepire e mānu ana, e tae ana ki te 1600-1700 nekehanga Celsius, ā, he rauemi ātete ahi tino pai. He māmā, he ārai, he ārai hoki. He angiangi, he takoto kau te pakitara pirepire e mānu ana, he haurua-korehau kei roto i te kōhao, ā, he iti noa te hau (N2, H2, CO2, me ētahi atu), ka puta he tino puhoi, he iti hoki te kawe wera. Nō reira, ehara i te mea he mama noa iho ngā pirepire mānu (me te taumaha kotahi o te 250-450 kirokaramu/m3), engari he pai hoki te whakamarumaru me te whakamarumaru wera (me te kawe wera o te 0.08-0.1 i te pāmahana rūma), e whakatakoto ana i te turanga mō tō rātou pūmanawa nui i roto i te mara o ngā rauemi whakamarumaru māmā. He pakeke me te kaha teitei. I te mea he karāhe mārō te pirepire mānu i hangaia e te wāhanga kohuke konukōnumo konukōre (quartz me te mullite), ka taea e tōna pakeke te tae ki te Mohs 6-7, ka taea e te kaha pēhanga pumau te tae ki te 70-140MPa, ā, ko tōna mātotoru tūturu ko te 2.10-2.20g/cm3, he rite ki te toka. Nō reira, he kaha teitei ngā pirepire mānu. I te nuinga o te wā, ko ngā rauemi pore māmā, pore rānei pērā i te Perlite, te toka kohua, te diatomite, te pumice, te vermiculite whānui, me ētahi atu he iti te pakeke me te kaha. Ko te ngoikoretanga o ngā hua whakamarumaru wera, ngā hua ātete māmā rānei i hangaia mai i aua mea, ko te ngoikore o te kaha. Ko tō rātou ngoikore ko te kaha o ngā pirepire mānu, e hoatu ana ki a rātou he painga whakataetae me te whānuitanga o ngā whakamahinga. He rahi matūriki angiangi, he whānui te horahanga mata motuhake. Ko te rahi matūriki tūturu o ngā pirepire e rere ana i waenga i te 1 ki te 250 maikorona. Ko te horahanga mata motuhake he 300-360cm2/g, he rite ki te sima. Nō reira, kāore e hiahiatia he huri i ngā pirepire e rere ana, ā, ka taea te whakamahi tika. Ka taea e te angiangi te whakatutuki i ngā hiahia o ngā momo hua. Ko ētahi atu rauemi whakamahana wera māmā he nui te rahi matūriki (pērā i te Perlite). Mena ka hurihia, ka nui ake te kaha, ā, ka tino whakaitihia te whakamahana. I tēnei whakaaro, he painga ngā pirepire e rere ana. He pai te whakamahana hiko. Ko te pirepire e rere ana i muri i te whiriwhiri i te pirepire aukume he rauemi whakamahana pai e kore e kawe hiko. Ka heke te ātete o ngā whakamahana whānui i te pikinga o te pāmahana, ko te ātete o ngā pirepire e rere ana ka piki ake i te pikinga o te pāmahana. Kāore tēnei painga i a ētahi atu rauemi whakamahana. Nō reira, ka taea te whakamahi hei hanga hua whakamahana i raro i ngā āhuatanga pāmahana teitei.
