Ngā Porowhita Karāhe Pokapū
Ko ngā porowhita karāhe tuwhera he porowhita karāhe tuwhera he rite te rahi ki te maikorona, he maeneene te mata, ko te nuinga he mea hanga ki te karāhe borosilicate houra-raima. I raro i te karuārai, ka puta mai he porowhita tuwhera, mārama. He maha ngā āhuatanga o ngā porowhita karāhe tuwhera, tae atu ki te iti o te kiato, te kaha teitei, te iti o te kawe wera, te nui o te tuku ngaru, te ārai hiko, te ātete pāmahana teitei, me te ātete waikawa me te kawakore. He pai hoki te rere o te wai me te pumau matū, e hanga ana i a rātou hei rauemi hou maha-mahi, hou hoki e whakamahia ana puta noa i ngā mara maha. He mea nui te whakamahinga o ngā porowhita karāhe tuwhera mō te whakapai ake me te arotau i te mahi a ngā rauemi rerekē, ā, he mea nui hoki mō te whakamama i ngā rauemi me ngā rautaki tiaki pūngao me te whakaiti i ngā tukunga.

Ngā Painga o ngā Maikoroporo Karāhe Pokapū
1. Māmā, nui te rōrahi: Ko te mātotoru tūturu o ngā porowhita karāhe tuwhera he tata ki te 1/10 o ngā whakakī tuku iho, ā, ka tino whakaiti i te taumaha motuhake o te hua i muri i te whakakī.
2. He tino pai te horapa me te rere o te wai: Ko tōna āhua porowhita ka whakarite kia maeneene te rere o ngā kapia, he pai ake te mahi whakakoi i ngā whakakī koretake. Nā te mea he isotropic, ka ārai i ngā raruraru whakatakotoranga, ka whakaiti i te whakahekenga koretake, ka whakapai ake i te pumau o ngā āhuatanga, ka whakaiti hoki i te piko.
3. Ārai wera, oro me te hiko, he iti te mimiti wai: He kaha te ārai wera me te ātete ki ngā ru wera o roto e whakaratohia ana e te hau whakangāwari o roto. He whānuitia te whakamahinga i roto i ngā rauemi wera me te ārai taura nā te mea he nui te ātete me te iti o te mimiti makuku.
4. He iti te mimiti hinu: He iti te horahanga o te mata o ngā matūriki porowhita, ka whakaiti i te hiahia mō te kapia. Ahakoa te nui o te uta, ka paku piki ake te matotoru, ka whakapai ake i te tukatuka me te whakanui ake i te whai huatanga mā te 10%-20%.
Ngā Whakamahinga o ngā Maikoroporo Karāhe Poka
He mama, he porowhita tuwhera ngā moroiti karāhe tuwhera, he mea whakamahi whānuitia i roto i te maha o ngā ahumahi nā te iti o te kiato, te whakamarumaru wera, me ngā āhuatanga kaha pēhi teitei.
E whakamahia whānuitia ana ēnei hei whakakī māmā i roto i ngā peita, i ngā paninga, i ngā kirihou, i ngā rapa, i ngā kapia epoxy, i ngā piripiri, me ngā rauemi hiato. Mā te tāpiri i ngā porowhita karāhe tuwhera, ka taea e ngā kaihanga te whakaiti i te taumaha o te hua, te whakapai ake i te whakamarumaru wera, te whakarei ake i te pumau o ngā āhuatanga, me te whakaiti i te whakamahinga o ngā rauemi.
I roto i te umanga hinu me te hau, ka whakamahia ngā porowhita karāhe tuwhera ki te whakapiringa i ngā puna hinu hei whakaiti i te kiato o te paru me te whakapai ake i te mahi. I roto i ngā mahi rererangi me te moana, ka whakamahia ēnei ki ngā pahuka honohono me ngā rauemi pōrewarewa nā te mea he pai rawa te ōwehenga kaha-ki-taumaha.
He whānuitia hoki te whakamahinga o ngā porowhita karāhe tuwhera i roto i ngā rauemi hanga, ngā paninga motuka, te paura putty, me ngā hua whakamahana. Mā te āhua porowhita maeneene ka pai ake te rere o te wai, ka whakaiti i te mimiti, ka whakarei ake hoki i te kounga o te mata.
