Ko ngā tāpare PVC (polyvinyl chloride) me ngā tāpare PE (polyethylene) he rauemi e whakamahia whānuitia ana, ā, he maha ngā mahi e mahia ana e rātou. I roto i tēnei whakatairite whānui, ka rukuhia e mātou ngā āhuatanga o ō rāua rauemi, ā rātou whakamahinga, ā rātou painga me ā rātou ngoikoretanga hei āwhina i a koe ki te whakatau whai whakaaro i runga i ō hiahia.
Mō te roa o te mau, he pai ake ngā tāpa PVC i ngā tāpa PE. He mea hanga ngā tāpa PVC kia roa mō te 10 tau, ko ngā tāpa PE ia ka roa mō te 1-2 tau, mō te whakamahi kotahi rānei. Ko te roa o te mau o ngā tāpa PVC nā te matotoru me te kaha o te hanganga, me te aroaro o te papanga mata kaha o roto.
I tētahi atu ringa, ko ngā tāpare PE, e mōhiotia ana ko ngā tāpare polyethylene, ko ngā tāpare HDPE rānei, he mea hanga mai i ngā poro polyethylene whatu kua pania ki te paparanga polyethylene iti-kiato (LDPE). Ahakoa kāore i te pakari pērā i ngā tāpare PVC, he painga anō ō ngā tāpare PE. He iti te utu, he māmā, he ngāwari hoki te whakahaere. Hei tāpiri, he ātete wai, he ātete wai, he ātete UV hoki hei tiaki pai i te rā. Heoi, he ngāwari ngā tāpare PE ki te poka me te haehae, ā, he iti ake te pono i roto i ngā āhuatanga uaua. Waihoki, kāore i te pai ki te taiao pērā i ngā tāpare kānawehi.
Nā, me tūhura tātou i ngā whakamahinga o ēnei tāpare. He pai ngā tāpare PVC mō ngā mahi taumaha. He maha ngā wā ka whakamahia i roto i ngā whare ahumahi hei whakarato i te tiaki pai mō ngā taputapu. He maha ngā wā ka whakamahia e ngā kaupapa hanga whare ngā tāpare PVC hei tūāpapa, hei pupuri paru, hei tiaki hoki i te huarere. Hei tāpiri, ka whakamahia hoki i roto i ngā uhi taraka me ngā tauera, ngā uhi whare kati kōtuhi me ngā mahi ahuwhenua. He pai hoki te tāpare PVC mō ngā uhi wāhi rokiroki o waho, kia pai ai te tiaki i te huarere. Hei tāpiri, he rongonui ēnei i waenga i ngā kaikamu me ngā hunga e aroha ana ki waho nā te mea he pakari, he pono hoki i roto i ngā wāhi whakangahau.
He rerekē, he whānuitia ngā whakamahinga o ngā tāpau PE. He mea whakamahi noa i roto i te ahuwhenua, te hanga, te kawe waka me ngā mahi whānui. He pai ake ngā tāpau PE mō te whakamahinga wā poto me te wā poto nā te mea he iti te utu. He pai te tiaki i a rātou mai i te harore, te koriri me te pirau, ā, he pai mō ngā momo taiao. Heoi, he ngāwari ki te poka me te haehae, ā, kāore i te pai mō ngā mahi taumaha.
Hei whakamutunga, ko te whiriwhiri i waenga i te tāpaurin PVC me te tāpaurin PE ka whakawhirinaki ki ō hiahia me tō tahua. He tino pakari, he ātete hoki ngā tāpaurin PVC, he mea pai mō ngā mahi taumaha. I tētahi atu taha, he iti te utu, he māmā hoki ngā tāpaurin PE hei whakatutuki i ngā hiahia wā poto me ngā hiahia wā poto. I mua i te whakatau, whakaarohia ngā āhuatanga pēnei i te whakamahinga e tika ana, te roa o te mau, me te pānga ki te taiao. He painga me ngā ngoikoretanga o ngā tāpaurin PVC me PE, nō reira whiriwhiria ma te whakaaro nui kia pai ai te whakamahi mō ō hiahia.
