Taketake: Te Mārama o ngā Pūrere
E mōhio ana tātou ko te mahi a te kāpia pou taha me te kāpia angaanga he whakapiri, nō reira e whakamahia ana e rāua te kāpia mārō, ko te nuinga he kāpia epoxy. Ko te kāpia epoxy e whakamahia whānuitia ana he wāhanga kotahi me te wāhanga-rua. Ko te wāhanga kotahi e pā ana ki te kaiwhakarato e whakarite ana i te tinana piri me te matū whakamaroke, me te nuinga o te wā me whakamatao kia kore ai e whakamaroke i te pāmahana rūma me te whakaiti i tōna mahi. Ko te piri wāhanga-rua he mea hanga mai i te tinana matua o te piri me te matū whakamaroke, ka taea te penapena i te pāmahana rūma. Heoi, me whakaranu kia ōrite kia rite ki te ōwehenga kua tohua, ki te kore, kāore pea e maroke tika.
He maha ngā tau kua pahure ake nei, he teitei ake te utu o ngā piripiri wāhanga kotahi, engari he iti iho te utu o ngā piripiri wāhanga-rua. He maha ngā kaihanga e whakatairanga ana i te whakamahinga o ngā piripiri wāhanga-rua nā te whakaaro ki te utu, engari he ngāwari ki te pakaru i te tunu nā te koretake o ngā ōwehenga, te whakaranu koretake rānei. I ngā tau tata nei, kua heke haere te utu o ngā piripiri wāhanga-tahi, ā, kua tata ngaro te painga utu o ngā piripiri wāhanga-rua. Ko te nuinga o ngā kaihanga e whakamahi ana i ngā piripiri wāhanga-tahi. Heoi, ka wehea te tohatoha pou taha ki te tohatoha mata pito me te tohatoha hononga, ā, he rerekē ngā piripiri e whakamahia ana i roto i ēnei tukanga e rua. Ko te piripiri e whakamahia ana mō te tohatoha mata pito ka pania ki te mata here o te huihuinga matua aukume, me te nui o ngā whakaritenga mō te rahi matūriki o te piripiri. Mena he matotoru rawa te rahi matūriki o te piripiri, he rite ki te whakanui ā-kore i te āputa hau o te whakawhiti, ka pā tika ki te ine hiko o te whakawhiti.
Tuarua, i te wā e pania ana te piri ki te mata o te pito, me aro hoki ki te pakeke o te piri. He nui te wāhi matua aukume kua pania ki te piri i te mata o te pito. Mena ka totoka te piri, ā, he nui te pakeke me te ahotea, ka pakaru tika te matua aukume. Nō reira, me whakamahi he piri he pakeke taurite. Mō te tuku piri ki te hononga o ngā pou taha, kāore i te tino teitei ngā whakaritenga mō te piri tonu. Heoi, me aro ki te kī tonu o te piri pou taha, ki te kore, kāore e taea te hanga i te kaha whai hua ki te matua aukume, ā, ka heke te kaha o te whakawhiti hiko i te wā e pakeke ana i te pāmahana teitei. Ko te tuku piri ki te pou waenganui hei whakaiti i te haruru, ā, ka whakamahia he piri ngohengohe. Me whakahaere tika te nui o te tuku. Mena he nui rawa te piri e tukuna ana, ka taea te whakawhānui i te piri i muri i te tunu me te pā ki te kaha; ki te iti rawa te nui o te tuku, kāore e taea te whakatutuki i te pānga tuku. Mō te whakamahinga tuturu, he mea tika kia whakamahia te 2/3 ki te 3/4 o te rōrahi o te āputa hau hei tohatoha i te pou pokapū.
I te nuinga o te wā, ko ngā wheketere whakawhiti hiko te mea e hiahiatia ana te nui rawa o te piripiri pou taha me te piripiri pou waenganui, engari he rerekē ngā piripiri e whakamahia ana mō ēnei e rua, ā, he ngāwari te whakapoauau. Nō reira, he pai ake te whakamahi i ngā tae e rua hei wehewehe i waenganui i a rāua kia kore ai e whakamahia ngā mea hē. Ko te tohatoha taha te mea e whakamahia ana mō ngā kiritaki whakamutunga ki te wero i te piripiri ki roto i te whakawhiti hiko, ā, he iti noa ngā whakaritenga. Ko te piripiri ngohengohe te mea e whakamahia ana hei piripiri, ka taea te whakaiti i te kaha kukume i runga i te matua aukume i muri i te whakapakeketanga o te piripiri. Ka taea te whakamahi i te momo whakamaroke hau taiao hei whakaiti i te tukanga whakaputa me te utu o ngā whakawhiti hiko. Me mōhio ko ngā piripiri katoa he matū, ā, he whakaritenga mō te roa o te wā e mau ana. Ka heke ngā āhuatanga piripiri e neke atu ana i te roa o te wā e mau ana, ā, kāore e tūtohutia kia whakamahia anō.
Mō te tukanga tohatoha katoa o te whakawhiti, ki te hiahiatia he tunu, he mea nui kia aro nui ki te pāmahana me te wā tunu kia tino maroke te kāpia, kia tutuki ai te hua tino pai. Ko te pāmahana tunu kāpia tuku iho ko te 100-120 ℃, ā, me whakahaere te wā i roto i te 0.5-1 hāora.
