3 Te hanganga o te muka karāhe
He rerekē te karāhe e whakamahia ana i roto i te hanga muka karāhe i te karāhe e whakamahia ana i roto i ētahi atu hua karāhe. Kei roto i te karāhe e whakamahia ana i roto i te hanga muka karāhe ngā wāhanga e whai ake nei:
(1)Karāhe-e,e mōhiotia ana ko te karāhe kore-waikawa, nō te karāhe borosilicate. I roto i ngā rauemi e whakamahia ana i tēnei wā mō te hanga muka karāhe, ko te karāhe kore-waikawa te mea e whakamahia whānuitia ana. He pai te whakamarumaru me ngā āhuatanga miihini o te karāhe kore-waikawa, ā, e whakamahia ana i te nuinga o te wā hei hanga muka karāhe whakamarumaru me ngā muka karāhe kaha-teitei, engari kāore te karāhe kore-waikawa e ātete ki te waikura waikawa inorganic, nō reira kāore e pai mō te whakamahi i roto i ngā taiao waikawa. Kei a mātou te karāhe-ete haereere i runga i te muka karāhe, karāhe-ete haereere whatu muka karāhe，me te karāhe-ewhāriki muka whakarewa.
(2)karāhe-C, e mōhiotia ana ko te karāhe kawakore waenga. Ki te whakatauritea ki te karāhe kore-kawakore, he pai ake te ātete matū me te ngoikore o ngā āhuatanga hiko me te miihini. Mā te tāpiri i te diboron trichloride ki te karāhe kawakore waenga ka putawhāriki mata muka karāhe,he ātete ki te waikura. Ko ngā muka karāhe kawakore-waenga kore-boron e whakamahia nuitia ana i roto i te hanga papanga tātari me ngā papanga takai.
Whāriki miro tapatapahi muka karāhe
(3)muka karāhe kaha-teitei,E ai ki te ingoa, ko ngā āhuatanga o te muka karāhe kaha-teitei ko te kaha teitei me te modulus teitei. Ko te kaha kume o tōna muka he 2800MPa, he 25% teitei ake i te muka karāhe kore-waikawa, ā, ko tōna modulus pīngore he 86000MPa, he teitei ake i te muka karāhe-E. Kāore i te teitei te putanga o te muka karāhe kaha-teitei, me tōna kaha teitei me te modulus teitei, nō reira e whakamahia whānuitia ana i roto i ngā taputapu hōia, ā-rangi me ngā taputapu hākinakina me ētahi atu mara, ā, kāore i te whānui te whakamahinga i roto i ētahi atu mara.
(4)muka karāhe AR, e mōhiotia ana ko te muka karāhe ātete-kawakore, he muka kore-waro. He pai te ātete kawakore o te muka karāhe ātete-kawakore, ā, ka taea te ātete ki te waikura o ngā matū kawakore teitei. He tino teitei tōna ātete ki te ngāwari me te pānga, te kaha kume me te kaha piko. Kei a ia anō hoki ngā āhuatanga o te kore e mura, te ātete ki te huka, te ātete ki te pāmahana me te haumākū, te ātete ki te pakaru, te kore e uru, te kaha kirihou me te ngāwari ki te hanga. He rauemi rara mō te raima whakakaha muka karāhe.
4 Te whakarite i ngā muka karāhe
