Ko te PVC Polyvinyl Chloride he kapia kirihou wera i whakapūhuitia mai i te Polyethylene Chlorinated i raro i te mahi a te kaiwhakaoho. He homopolymer o te Vinyl Chloride. He whānuitia te whakamahinga o te PVC i roto i ngā rauemi hanga, ngā hua ahumahi, ngā mea e hiahiatia ana i ia rā, te hiako papa, ngā taera papa, te hiako horihori, ngā paipa, ngā waea me ngā taura, ngā kiriata takai, ngā pounamu, ngā rauemi pahuka, ngā rauemi hiri, ngā muka, me ētahi atu.
Ko ngā painga nui o ngā hua kirihou PVC whānui ko te ātete mura, te ātete kakahu, te ātete waikura matū, me te iti o te turuturu hau me te kohu wai. Hei tāpiri, he pai hoki te pūngao miihini whānui, ngā hua mārama, te whakamarumaru hiko, te whakamarumaru wera, te whakaiti haruru, me te mimiti ru, ā, koinei te rauemi whānui tino whai hua. Heoi, ko ōna ngoikoretanga ko te kore pumau wera me te ātete pānga, ka ngāwari te pakarukaru i te wā e whakamahia ana te PVC mārō me te PVC ngohengohe. Nā te mea he kirihou mārō te PVC, kia ngohengohe ai, kia pai ake ai te ātete pānga, me tāpiri he nui o te plasticizer.
He tino pai te polyethylene CPE kua whakakōkōhia ki te hauota mō te PVC. He tino pai te ātete pānga pāmahana iti o te Polyethylene CPE kua whakakōkōhia ki te hauota, nō reira e whakamahia ana hei whakarerekē pānga mō ngā hua PVC mārō. Ko te horopeta o te CPE momo 135a e whakamahia ana hei whakarerekē pānga mō ngā kōtaha PVC he 9-12 ngā wāhanga, ā, ko te horopeta o te 4-6 ngā wāhanga e whakamahia ana hei whakarerekē pānga mō ngā paipa wai PVC, ētahi atu paipa kawe wai pēhanga rānei, e whakapai ake ana i te ātete pānga pāmahana iti o ngā hua PVC. I te nuinga o te wā, ko te tāpiri i te Polyethylene kua whakakōkōhia ki ngā hua PVC he maha ngā pānga e whai ake nei: te whakanui ake i te pakari o te hua, te whakapai ake i te ātete pānga, me te whakarerekē i te kaha o te hua.
Hei tāpiritanga, ka tāpirihia whānuitia te CPE 135A Chlorinated Polyethylene ki ngā rau PVC, ki ngā rau, ki ngā pouaka kirihou konupūmā, ki ngā anga taputapu kāinga, me ngā taputapu hiko hei whakapai ake i ngā āhuatanga ā-tinana, ā-pūkaha, me te hiko o ngā hua PVC.
