He pūmua te nairona, arā, he kirihou kei roto i te hanganga ngota he maha ngā wae rite e honoa tahi ana. He rite tonu ki te mekameka whakarewa, he mea hanga mai i ngā hononga tāruarua. He whānau katoa te nairona o ngā momo rauemi tino rite e kiia nei ko ngā polyamides.
Ko tētahi take i puta ai he whānau nairona nā DuPont i pateni te āhua taketake, nō reira me rapu huarahi kē atu ngā kaiwhakataetae. Ko tētahi atu take he rerekē ngā āhuatanga me ngā whakamahinga o ngā momo muka rerekē. Hei tauira, ko Kevlar® (te rauemi koti ātete matā) me Nomex® (he papanga ātete ahi mō ngā hūtu waka reihi me ngā karapu oumu) he hononga matū ki te nairona.
Kei te taiao ngā rauemi tuku iho pēnei i te rakau me te miro, engari kāore te nairona. Ka hangaia he pūmua nairona mā te tauhohenga tahi i ngā ngota ngota nui e rua mā te whakamahi i te wera tata ki te 545°F me te pēhanga mai i tētahi ipu wai kaha-ahumahi. Ina honoa ngā waeine, ka hanumi hei hanga i tētahi ngota ngota nui ake. Ko tēnei pūmua nui te momo nairona tino noa—e mōhiotia ana ko te nairona-6,6, e ono ngā ngota waro kei roto. Mā te tukanga ōrite, ka hangaia ētahi atu momo nairona mā te tauhohenga ki ngā matū tīmatanga rerekē.
Mā tēnei tukanga ka hangaia he rau, he rīpene nairona rānei, ka haehaea kia rite ki ngā maramara. Ko ēnei maramara te rauemi mata mō ngā momo hua o ia rā. Heoi, ehara i te mea he maramara ngā papanga nairona, engari he muka nairona, arā, he miro kirihou. Ka hangaia tēnei miro mā te whakarewa i ngā maramara nairona, ka kumea mā roto i tētahi wira hurihuri, he pū kōhao iti nei. Ka hangaia ngā muka rerekē te roa me te matotoru mā te whakamahi i ngā pū kōhao rerekē te rahi, ka kumea ki waho i ngā tere rerekē. Ko te maha o ngā miro kua takaihia, ko te tikanga he matotoru ake, he kaha ake te miro.
