Ngā mea whakaū konupūmā konutea wai, hei momo rauemi mahi e taea ai te tukatuka i ngā hua ngohengohe PVC, kua whakamahia whānuitia i roto i ngā whitiki kawe PVC, ngā taonga takaro PVC, te kiriata PVC, ngā kōtaha kua whakaputahia, ngā hu me ētahi atu hua. He pai ki te taiao, kāore hoki he paitini ngā whakaū konupūmā konutea wai, he pai te pumau o te wera, te marara, te ātete ki te huarere me ngā āhuatanga ārai-pakeke.
Ko ngā wāhanga matua o ngā whakaū konupūmā konutea wai ko: ngā tote waikawa waro o te konupūmā me te konutea, ngā whakarewa mengā whakaū wera āwhina rauropi.
Whai muri i te whakamahinga matū o ngā tote konupūmā me te konutea, ko te tikanga matua o te pumau ko te pānga tahi o ngā tote konupūmā me te konutea. Ka taea e ēnei tote konutea te whakaputa i ngā konupūmā waikawa Lewis ZnCl2 ina mimitihia te HCl. He kaha te pānga whakaterenga a te ZnCl2 ki te pakaru o te PVC, nō reira ka whakatairanga i te tango i te waikura o te PVC, ka tere te pakaru o te PVC. Whai muri i te whakakotahitanga, ka aukatihia te pānga whakaterenga a te ZnCl2 ki te pakaru o te PVC mā te tauhohenga whakakapinga i waenga i te tote konupūmā me te ZnCl2, ka taea te aukati i te wera o te konutea, te whakarite i te mahi tae wawe pai me te whakarei ake i te pumau o te PVC.
Haunga te pānga mahi tahi whānui kua whakahuatia i runga ake nei, me whai whakaaro anō hoki ki te pānga mahi tahi o ngā whakaū wera āwhina waro me ngā whakaū tuatahi i te wā e whakawhanake ana i ngā whakaū konupūmā konutea wai, koinei anō hoki te arotahi o te rangahau me te whakawhanaketanga o ngā whakaū konupūmā konutea wai.
