E toru ngā tukanga e taea ai te wehewehe i te pahuka kirihou: te hanganga o ngā karihi mirumiru, te whakawhānui o ngā karihi mirumiru, me te whakapakeketanga o ngā tinana pahuka. Mō ngā pepa pahuka PVC, he pānga nui te whakawhānui o te matua mirumiru ki te kounga o te pepa pahuka. Nō ngā ngota mekameka tika te PVC, he poto ngā mekameka ngota, he iti hoki te kaha rewa. I te tukanga o te whakawhānui o te mirumiru ki roto i ngā mirumiru, kāore e ranea te rewa hei taupoki i ngā mirumiru, ā, ka ngāwari te hau ki te puea ake, ka hanumi ki roto i ngā mirumiru nui, ka whakaiti i te kounga o te hua o ngā pepa pahuka.
Ko te mea matua hei whakapai ake i te kounga o ngā pepa pahuka PVC ko te whakanui ake i te kaha rewa o te PVC. Mai i te tātari i ngā āhuatanga tukatuka o ngā rauemi polymer, he maha ngā tikanga hei whakapai ake i te kaha rewa o te PVC, ko te huarahi tino whai hua ko te tāpiri i ngā tāpiri hei whakapai ake i te kaha rewa me te whakaiti i te pāmahana tukatuka. No ngā rauemi kore-āhua te PVC, ā, ka heke te kaha rewa i te pikinga o te pāmahana rewa. I tetahi atu taha, ka piki ake te kaha rewa i te hekenga o te pāmahana rewa, engari he iti noa te pānga whakamatao, ā, he mahi āwhina anake. Ko te pānga o ngā kaihoko tukatuka ACR he whakapai ake i te kaha rewa, ko ngā kaiwhakahaere pahuka te mea tino whai hua. Ka piki ake te kaha rewa i te pikinga o te ihirangi kaiwhakahaere pahuka. I te nuinga o te wā, mena he nui te kaha marara me te whakaranu o te tīwiri, he nui ake te pānga o te tāpiri i ngā kaiwhakahaere pahuka matotoru ki te whakapai ake i te kaha o te rewa. Ko te tūranga o ngā āwhina tukatuka i roto i ngā pepa pahuka PVC: Ka whakatairanga ngā āwhina tukatuka ACR i te rewa o te PVC, ka whakapai ake i te maeneene o te mata, ka whakapai ake i te ngāwari o te rewa, ka whakarei ake i te roa me te kaha o te rewa. He pai mō te takai i ngā mirumiru me te ārai i te hinga o ngā mirumiru. He pānga nui tō te taumaha ngota me te horopeta o ngā kaiwhakahaere pahuka ki te mātotoru o ngā pepa pahuka: i te pikinga o te taumaha ngota, ka piki ake te kaha o te rewa PVC, ā, ka taea te whakaiti i te mātotoru o ngā pepa pahuka, he rite tonu te pānga ki te whakanui ake i te horopeta o ngā kaiwhakahaere. Engari kāore he hononga rārangi o tēnei pānga. Ki te whakanui tonu i te taumaha ngota, i te horopeta rānei, kāore he pānga nui ki te whakaiti i te mātotoru, ā, ka noho pūmau te mātotoru.
He hononga nui kei waenganui i ngā kaiwhakahaere pahuka me ngā kaihoko pahuka. He pūwāhi taurite kei waenganui i te mātotoru o ngā pepa pahuka me ngā kaiwhakahaere pahuka. I tua atu i tēnei pūwāhi taurite, kāore te mātotoru o ngā pepa pahuka e pāngia e te nui o ngā kaihoko pahuka, ā, ka noho tonu. Arā, mā te whakanui ake i te nui o te kaihoko pahuka e kore e taea te whakaiti i te mātotoru. Ko te take o tēnei āhuatanga, i raro i tētahi nui o ngā kaiwhakahaere pahuka, ka iti te kaha rewa o te PVC, ā, ka taea e te hau nui te hinga, te hanumi rānei o ngā pūtau pahuka.
