He aha te karāhe whakakikoruatia?
Karāhe whakakikoruatiahe mea tito mai i ngā wahi karāhe e rua, neke atu rānei, me tētahi, neke atu rānei ngā paparanga o ngā paparanga pūmua waro e piri ana ki waenganui i a rāua. Whai muri i ngā tukanga pēhi-mua pāmahana teitei motuhake (te whakakore rānei i te puehu) me ngā tukanga pāmahana teitei me te pēhanga teitei, ka herea pumau te karāhe me te paparanga hei hua karāhe hiato.
Ko ngā kiriata paparanga karāhe whakakikoruatia e whakamahia whānuitia ana ko: PVB, SGP, EVA, me ētahi atu. Ā, he maha ngā tae me te kaha whakawhiti o te paparanga hei whiriwhiri mā rātou.
Ngā Pūāhua o te Karāhe Whakakirikiri:
Ko te tikanga o te karāhe whakakikoruatia ko te karāhe kua whakamaroketia, ā, kua tukatukahia kia haumaru hei hono i ngā wāhanga karāhe e rua. I muri i te pakaru o te karāhe, kāore e tauhiuhi, e whara rānei i te tangata, ā, he mahi haumaru anō hoki. He tino haumaru te karāhe whakakikoruatia. Nā te mea he pakari te kiriata o te paparanga waenga, ā, he kaha te piri, kāore e ngāwari te uru atu i muri i te pakaru, ā, kāore ngā kongakonga e taka, ā, he piri pūmau ki te kiriata. Ki te whakatauritea ki ētahi atu karāhe, he ātete ki te ru, he ārai tahae, he ātete matā, he ātete pahū hoki.
I Ūropi me te Hononga o Amerika, ko te nuinga o ngā karaihe hoahoanga e whakamahi ana i te karaihe whakakikoruatia, ehara i te mea hei karo i ngā whara anake, engari nā te mea he tino pai te ātete o te karaihe whakakikoruatia ki te ru. Ka taea e te paparanga waenga te ātete i ngā whakaekenga tonu a ngā hama, ngā toki me ētahi atu patu. I roto i ēnei, ka taea hoki e te karaihe whakakikoruatia ātete matā te ātete i te urunga o te matā mō te wā roa, ā, ka taea te kī he tino teitei tōna taumata haumarutanga. He maha ngā āhuatanga pēnei i te ātete ru, te ārai tahae, te ātete matā me te ātete pahūtanga.
Rahi karāhe whakakikoruatia: rahi mōrahi 2440*5500(mm) rahi iti rawa 250*250(mm) Ko te matotoru o te kiriata PVB e whakamahia whānuitia ana: 0.38mm, 0.76mm, 1.14mm, 1.52mm. Ko te matotoru o te matotoru o te kiriata, ko te pai ake o te ātete-pahūtanga o te karāhe.
