Ngā Kaiwhakarato Miro Karāhe Hainamana rarawe - Te Ārai Wera, Te Iti te Ngongo Wai, Ngā Poro Karāhe Kohao – Kehui

He mama, he nui te rahinga, he iti te kawe wera, he kaha pēhi teitei, ā, he pai te rere o ngā porowhita iti o te karāhe tuwhera. E whakamahia ana ēnei hei whakakī hua me ngā kaihoko whakamārama i roto i ngā paninga peita, rapa, kirihou whakarerekētia, kirihou whakakaha muka karāhe, kohatu horihori, putty me ētahi atu ahumahi; i roto i ngā ahumahi keri hinu me te hau, nā te kaha o te ātete pēhi me te iti o te mātotoru ka taea te whakaputa i te paru sima iti-mātotoru kaha teitei me te wai keri iti-mātotoru.
Ko ngā porowhita karāhe tuwhera he porowhita karāhe tuwhera he iti noa te rahi, he rauemi kore-whakarewa kore-waro. Ko te whānuitanga rahi matūriki noa ko te 28-120 maikorona, ā, ko te matotoru papatipu ko te 0.2-0.6 karamu/cm3. He painga tōna: he māmā, he iti te kawe wera, he ārai oro, he nui te horapa, he pai te ārai hiko me te pumau wera. He rauemi mama hou tēnei kua whakawhanakehia, he whānui ngā whakamahinga me te mahi tino pai.
1: He mā parakore te tae o te āhua. Ka taea te whakamahi whānuitia i roto i ngā hua katoa e hiahiatia ana te āhua me te tae.
2: He māmā te taumaha motuhake, he nui te rōrahi. Ko te mātotoru o ngā porowhita karāhe tuwhera he tata ki te kotahi tekau o te mātotoru o ngā matūriki whakakī tuku iho. I muri i te whakakī, ka taea te whakaiti i te taumaha pūtake o te hua, te whakakapi me te penapena i ngā kapia whakaputa, me te whakaiti i ngā utu hua.
3: He mata kua whakarerekētia ā-pūtaiao (lipophilic). He ngāwari te whakamakuku me te horapa o ngā porowhita karāhe tuwhera, ā, ka taea te whakakī ki te nuinga o ngā kapia kirihou whakamahana, pērā i te polyester, pp, pvc, epoxy, polyurethane, me ētahi atu.

Kei te tukuna hoki ngā porowhita iti karāhe tuwhera me ngā paninga kawe hiko. Mā te paninga kawe hiko me te matotoru kua arotauhia ka whakaratohia he āhuatanga kawe hiko me te tiaki pai mō ngā matūriki porowhita, me te pupuri tonu i te painga penapena taumaha e pā ana ki ngā rauemi iti-kiato-matua tuwhera. He pai ēnei mirumiru kawe hiko mō te whakamahi i roto i ngā mahi hōia, te hangarau koiora, ngā taputapu hauora, ngā hikohiko, me ētahi atu ahumahi motuhake.

Ngā whakamahinga matua o ngā porowhita karāhe tuwhera:
1. Mā te whakarerekētanga o te nairona, PP, PBT, PC, POM, PVC, ABS, PS me ētahi atu kirihou ka taea te whakapai ake i te rere o te wai, te whakakore i te pānga o te muka karāhe, te whakakore i te piko, te whakapai ake i ngā āhuatanga ārai mura, te whakaiti i te kai muka karāhe, me te whakaiti i ngā utu whakaputa.
2. Mā te whakakī i te PVC pakari, PP, PE, te whakaputa i ngā kōtaha, ngā paipa me ngā pepa, ka taea te whakapai ake i te pumau o ngā hua, te whakapai ake i te pakari me te ātete wera i te pāmahana, te whakapai ake i te mahi utu hua, te whakapai ake i te pai o te whakaputa me te whakaiti i ngā utu.
3. Mēnā ka whakakīia ki te PVC, PE me ētahi atu taura me ngā rauemi hipoki ārai, ka taea te whakapai ake i te ātete pāmahana teitei o te hua, te ārai wera, te ātete waikawa me te kawakore me ētahi atu āhuatanga me te mahi tukatuka hua, te whakanui ake i te putanga me te whakaiti i ngā utu.
