He aha ngā peita mō ngā waka?
Ko te peita waka he peita e whakamahia ana i runga i ngā waka mō ngā kaupapa tiaki me ngā kaupapa whakapaipai.[1][2] Ko te peita enamel polyurethane kiriaku wai te peita e whakamahia whānuitia ana i tēnei wā, tae atu ki te whakaiti i te pānga o te peita ki te taiao.
He maha ngā paparanga o te peita waka o ēnei rā, ā, ko te matotoru katoa he tata ki te 100 µm (0.1mm). Me whakarite te paninga peita me ngā mahi paninga tuatahi kia tika ai te paninga. Ka pania he paninga turanga i muri i te paninga o te peita paninga tuatahi. Whai muri i tēnei, ka taea te pania he paninga mārama hei hanga i tētahi paninga kanapa, mārama hoki. Me kaha te paparanga paninga mārama ki te tu atu i te mārama UV.

E whakamahia ana ngā cenospheres me ngā microspheres karāhe i roto i ngā momo ahumahi, tae atu ki te peita motuka, hei whakarei ake i ngā āhuatanga o ngā paninga. Heoi, i roto i te horopaki o te peita motuka, ngā porowhita iti o te karāhe he nui ake te whakamahinga i ngā cenospheres.
Ngā porowhita iti o te karāhe He porowhita karāhe iti, he tuwhera, e tāpirihia ana ki ngā peita motuka hei whakapai ake i ō rātou āhuatanga. He mama, he iti te mātotoru, e āwhina ana ki te whakaiti i te taumaha katoa o te peita me te kore e whakaiti i tōna rahinga. Ka hua ake tēnei i te pai ake o te whakamahinga wahie me te pai ake o te mahi a te waka. Ka whai wāhi hoki ngā porowhita karāhe ki te roa o te peita, nā te mea ka taea e rātou te hanga i tētahi ārai hei āwhina i te aukati i te urunga o te makuku me te waikura.
Ngā Aorangi, i tētahi atu ringa, he hua taha o te tahunga waro, ā, e whakamahia nuitia ana i roto i ngā ahumahi pēnei i te hanga whare, te keri hinu, me te whakamahana. Ahakoa he āhuatanga ahurei ō rātou, pēnei i te ātete ki te pāmahana teitei, kāore i te whakamahia whānuitia i roto i ngā peita motuka pērā i ngā porowhita iti o te karāhe.
Hei whakarāpopototanga, he nui ake te whakamahinga o ngā porowhita iti o te karāhe i roto i te peita motuka nā runga i ō rātou painga motuhake me te hototahi ki ngā hanganga paninga.
