He rauemi rongonui te karāneti mō te hanga wāhanga mīhini nā tōna pakeke, tōna roa, me tōna ātete ki te pakaru me te pakaru. Heoi anō, tera tonu ētahi hapa i roto i ngā wāhanga mīhini karāneti ka pā ki tōna kounga me tōna mahi.
Ko tētahi o ngā hapa e kitea whānuitia ana i roto i ngā wāhanga mīhini karāhe ko ngā pakaru. He pakaru, he rārangi rānei ēnei e puta ana i runga i te mata, i roto rānei i te wāhanga nā te ahotea, te pānga, te huringa pāmahana rānei. Ka taea e ngā pakaru te ngoikore o te wāhanga, ā, ka pakaru wawe.
Ko tētahi atu hapa ko te porosity. Ko ngā wāhanga mīhini karāhe porosity ko ērā he iti ngā pute hau, he āputa rānei i roto. Ka taea e tēnei te hanga i a rātou kia pakarukaru, kia ngawari hoki te ngatata, te pakaru rānei i raro i te taumahatanga. Ka pā hoki te porosity ki te tika o ngā āhuatanga o te wāhanga, ka hua ake he hapa i roto i te mīhini.
Ko te tuatoru o ngā hapa ko te whakaotinga o te mata. Tērā pea he koretake, he taratara rānei ngā whakaotinga mata o ngā wāhanga mīhini karāhe, ā, ka pā ki tā rātou mahi. Ka taea e te taratara te whakararuraru, ka nui ake te pakaru me te pakaru o te wāhanga. Ka taea hoki e ia te uaua ki te whakairi, ki te huihui rānei i te wāhanga kia tika.
Hei whakamutunga, ka pā pea te kounga o te karāhe i whakamahia ki te hua. Tērā pea he poke, he rerekētanga rānei kei roto i te karāhe kounga iti, ka pā ki tōna pakeke, tōna roa me tōna ātete ki te kakahu. Ka taea e tēnei te arahi ki te whakakapinga me te whakatikatika pinepine i ngā wāhanga o te mīhini.
Heoi, he mea nui kia mōhiotia ka taea te whakaiti, te whakakore rānei i ēnei hapa mā te whakamahi i ngā tukanga hanga tika me ngā tikanga whakahaere kounga. Hei tauira, ka taea te ārai i ngā kapiti mā te whakamahi i te karāhe kounga pai me te whakahaere i te pāmahana me te ahotea i te wā miihini. Ka taea te whakakore i te porosity mā te whakamahi i te tukanga whakakī korehau hei whakakī i ngā āputa ki te kapia, ki te polymer rānei. Ka taea te whakapai ake i te mutunga o te mata mā te whakakanapa me te whakamahi i ngā taputapu tapahi tika.
Hei whakamutunga, he kōwhiringa pono, he kōwhiringa pakari hoki ngā wāhanga mīhini karāhe mō ngā mīhini. Mā te whakarite i ngā mahi hanga me te whakahaere kounga tika, ka taea te whakaiti i ngā hapa, ā, ka taea te whakanui ake i te roa o te mahi me te mahi a ngā wāhanga.
