Ngā Pūrongo

Ko te muka pātarati kei roto ko te tinana o te mātiti hī ika, ā, kotahi te paparanga o te paparanga whiri i roto i te tinana o te mātiti hī ika. Ka whakamahia te muka pātarati ki te whiri mā te ara mā, mā te ara twill rānei, nā te mea he kaha te muka pātarati tonu, engari he pai hoki te ārai hiko, te ātete ki te waikura, te ātete ki te pāmahana teitei, me ētahi atu mahi pai.

Ko te whatanga papara ātete mura mō te maina waro i raro i te whenua, he momo whatanga i hangaia mō ngā mahi tautoko maina waro i raro i te whenua. He āhuatanga ātete mura me te ātete-pūmau tōna, ka taea te whakapai ake i te tauwehenga haumaru o te maina waro i raro i te whenua.

He rauemi hanga whānuitia te raima i roto i te hangarau ā-iwi, ā, he pai ōna āhuatanga miihini, engari nā te hohonu haere o te whakamahinga o te hangarau miihini, ka āta kitea ngā ngoikoretanga o ōna āhuatanga miihini taketake. Nā te iti o ngā āhuatanga kaha kume, kotahi te whakatekau o te kaha kume, ka hua ake he ngāwari te pakaru o ngā mema o te tukanga kume, ka whakaiti tika i te pakari o ngā wāhanga, ka whakawhāiti i te whānuitanga o te whakamahinga o ngā rauemi raima.

I tēnei wā, he maha ngā kamupene e mahi ana i ngā rangahau mō te hanga hua nui o ngā mea kakara. muka pātarati, engari kei te mau tonu ētahi raruraru hangarau i roto i te whakaputanga, pērā i te kaha nui o ngā waeine e pā ana, te iti o te whai huatanga o te whakaputanga, me ētahi atu take. He kaupapa pūnaha te whakaputa oumu puna kaukau muka basalt, me haere tonu te ako me te whakapai ake i ngā taputapu tautoko e pā ana, kia whakatauhia ai ia hononga hei pupuri i te whanaketanga.

I roto i te umanga kirihou hangarau whakarerekētia, ko ngā rauemi honohono kua whakapakarihia ki te muka roa he rauemi honohono i hangaia mai i ngā muka waro roa, ngā muka karāhe roa, ngā muka aramid, ngā muka basalt rānei me te hanganga polymer mā roto i te raupapa o ngā tikanga whakarerekētanga motuhake. Ko te āhuatanga nui o ngā rauemi honohono muka roa ko te pai ake o te mahi kāore i te rauemi taketake.

Ko te muka tonu o te pātara he momo rauemi kore-whakarewa taiao parakore, he rauemi hou o te rautau 21, ā, ko tētahi o ngā wāhanga tino nui o te umanga rauemi hou. He rite te muka pātara ki te muka karāhe, ko tōna mahi kei waenganui i te muka karāhe S kaha teitei me te muka karāhe E kore-waikawa, he muka hangarau-teitei taiao parakore, nā te mea he parauri koura te tae o te muka, e mōhiotia ana ko te "muka koura".

He rauemi auaha te rebare basalt e arohia ana e te umanga hanga nā tōna pakari me tōna kaha. He mea hanga mai i te basalt, he otinga whai hua tēnei hei whakakapi i ngā pae rino tuku iho mō ngā hanganga hanga e hiahia ana ki ngā rauemi roa, pumau hoki. I roto i tēnei tuhinga, ka tūhuratia e mātou te pakari o te rebare basalt, ā, ka whakautua te pātai e whai ake nei: Kia pēhea te roa o te ora o te rebare basalt?

He momo hou te muka pātarati o te muka kakariki mahi-teitei kore-waro, he mea hanga mai i te silica, te alumina, te waikura konupūmā, te waikura konupūmā, te waikura rino me te hauhā titanium me ētahi atu waikura. Ehara i te mea he kaha teitei anake te muka tonu o te muka pātarati, engari he maha hoki ngā āhuatanga pai pērā i te ārai hiko, te ātete ki te waikura, te ātete ki te pāmahana teitei me ētahi atu.

Mā te whatu whatu i hangaia ki te mata whatu, ka taea te pani i te mata ki te muka papa papa. Ko te papa papa papa te mea e whakamahia ana mō te whakakaha i te papa uku, te whakakaha i te papa rori me te turanga oneone ngohengohe.
