Ka pania te miro muka karāhe ki te rauemi waro hei whakapai ake i tōna ngāwari, ā, ka whakamahia hei hanga kakahu takai, ārai matapihi, uhi pakitara, kakahu hipoki, me ngā kākahu tiaki. Me ngā rauemi whakamahana me te whakamahana oro.
Me pēhea te wehewehe i te kounga o te Fiberglass Roving?
He mea hanga te muka karāhe i te karāhe hei rauemi mata, ā, ka tukatukahia mā roto i ngā tikanga whakakoi i roto i te āhua rewa. I te nuinga o te wā ka wehea ki te muka karāhe tonu me te muka karāhe motumotu. I te mākete, he maha atu ngā muka karāhe tonu e whakamahia ana. E rua ngā hua matua o te muka karāhe tonu.

Ko te rerekētanga matua i waenganui i a rāua ko te nui o ngā waikura konganuku kawakore. Ko te muka karāhe kawakore-waenga ko te (12±0.5)%, ā, ko te muka karāhe kore-kawakore ko te <0.5%. Kei te mākete anō hoki tētahi hua muka karāhe kore-paerewa. E mōhiotia whānuitia ana ko te muka karāhe kawakore-teitei. Neke atu i te 14% te nui o ngā waikura konganuku kawakore. Ko ngā rauemi mata mō te hanga he karāhe papatahi pakaru, he pounamu karāhe rānei. He iti te ātete wai o tēnei momo muka karāhe, he iti te kaha miihini, ā, he iti te ārai hiko, kāore e whakaaetia kia hangaia e ngā ture ā-motu.
Me takai pūmau ngā hua miro muka karāhe reo-kawai me te kore-kawai ki runga i te miro, ā, me tohu ia miro ki te tau, te tau o te whenu me te tohu, ā, me whakahaere te manatoko tirotiro hua i roto i te pouaka tākai. Ko ngā ihirangi o te tirotiro me te manatoko hua ko:
1. Te ingoa o te kaihanga;
2. Te waehere me te tohu o te hua;
3. Tau o tēnei paerewa;
4. Tāia he hiri motuhake hei tirotiro i te kounga;
5. Taumaha kupenga;
6. Me whakauru te ingoa o te wheketere, te waehere me te tohu hua, te tau paerewa, te taumaha kupenga, te rā whakaputa me te tau puranga, me ētahi atu mea ki roto i te pouaka takai.
