;Ngā porowhita karāhe tuwhera He maha ngā whakamahinga, engari ko tētahi o ngā mea tino rongonui ko te hanga hua pēnei i ngā hiri rapa silicone. Ko te painga nui o ngā porowhita iti karāhe tuwhera ko te whakaiti i te taumaha e ngāwari ai te tono mō te kawe maeneene. Ka whakaratohia e tā mātou porowhita iti karāhe he whakamarumaru, he pakari, he pumau hoki e āwhina ana i te kawe me ētahi atu whakamahinga anō hoki.
Me pēhea te whakamahi i te rapa?
Mō ngā rangahau, me mārama ko te rahi o te matūriki, tōna kaha ki te hono, me te kawenga ki te whakatau i te kaha, te ātete, me te pakari o ētahi rauemi whakakotahi. He maha ngā rangahau i whakatau ko ngā āhuatanga o te rapa i tino piki ake i te wā i whakauruhia ai te karāhe moroiti tuwhera ki roto. E whakaatu ana hoki ngā rangahau mēnā he iti te matotoru o te rewa o tētahi mea, ka taea te hanga mā te whakamahi i ngā karāhe moroiti tuwhera i roto i te polyester me ngā kapia epoxy.
I tētahi atu rangahau, ko te whanonga o ngā porowhita karāhe tuwhera i rangahauhia te pakaru me te kaha i te wā i whakauruhia ai ki roto i ngā mea honohono pērā i te rapa. He nui ake te kaha o ngā porowhita karāhe tuwhera i te hanga motuhake o te mea honohono. I tua atu, i te wā i hangaia ai ngā momo mea honohono mai i ngā porowhita karāhe tuwhera, i kitea ko te roa o te mau o te rauemi ka nui ake te mātotoru o te porowhita karāhe tuwhera i roto i te rauemi i te wā e whakauruhia ana. I tua atu, i piki ake te kaha mō te mimiti i te kaha o te rauemi ki te 40% mā te whakamahi i te porowhita karāhe tuwhera. Ko tētahi o ngā rangahau tino nui ko te āhua dielectric o ngā porowhita karāhe tuwhera i whakakīia ki ngā mea honohono whakakapi, ā, i kitea i piki ake te ōritetanga me te heke o ngā ngaronga i runga i te dielectric i te wā i tāpirihia ai ngā porowhita karāhe tuwhera ki te nui haere. I tua atu i te horopaki o te pakaru i runga i te porowhita karāhe tuwhera, i kitea ko te whakaurunga o ngā porowhita iti i whakanui ake i te modulus piko me te whakaiti i te pakari me te kaha i runga i te pakaru.
He rauemi tino motuhake te moroiti tuwhera, he mea kore-waro hoki te āhua, ā, he maha ngā whakamahinga. Ko te painga nui o tō rātou moroiti tuwhera ko te whakanui ake i te wehenga mai i te wera, ā, he tino mātotoru te hau. Nō reira, i roto i te whakamahinga mahi i roto i te umanga rapa, ko tētahi āhuatanga tino nui ko tōna whakaurunga ki te rapa silicone e kapi ana i ngā porowhita kore-mate me ngā porowhita pakaru i roto i ngā ōwehenga motuhake. Ko te whakamahinga i roto i te umanga rapa e kī ana ahakoa ka pakaru ngā moroiti karāhe tuwhera, ka whakanui ake i ēnei āhuatanga kua kōrerohia i runga ake nei.
