Ko te rerekētanga i waenga i te whakaū konupūmā konutea me te whakaū tote mata

Ko te whakapūmau konupūmā konutea me te whakapūmau tote mata hiato e pā ana ki ngā whakapūmau wera PVC e whai wāhi ana ki te pumau wera i roto i te hanga hua PVC. Ko te rerekētanga i waenga i ngā mea e rua koia tēnei:

E tutuki ana i ngā whakaū wera konupūmā konutea ngā whakaritenga taiao, ā, e whakamahia whānuitia ana i tēnei wā. Ko ōna āhuatanga ko ēnei āhuatanga e whai ake nei:

1. Ko te āhuatanga tino nui o ngā whakapūmau konupūmā konutea ko tōna whakamahinga i roto i ngā whakatakotoranga hua mārama, me ngā whakatakotoranga hua mātotoru hoki i roto i ngā rauemi hanga matū, ā, he kaha te whakamahinga.

2. He iti iho te utu i te tine waro.

3. He pai te hototahi me te mahi tahi me ngā mea whakaū mata, tine, cadmium, me te antimony, ā, kāore he parahanga whanariki. He pai mō ngā kaihanga kua whakamahi kē i ngā mea whakaū tote mata hei whakakapi i ngā hua kore-paitini, ā, he pai hoki mō te taiao.

4. Ko tētahi atu painga nui o ngā whakapūmau konupūmā konutea ko tōna ātete pai ki te huarere, ā, ko ngā hua e hangaia ana me ngā whakapūmau hiato konupūmā konutea whai tohu e kore e puta he tae ke.

E rua ngā momo matua o ngā whakaū tote mata, arā, ko ngā monomer me ngā hiato, ā, ko ngā whakaū tote mata te nuinga o te wā e whakamahia ana hei whakaū matua i Haina. Ka whakamahia e te whakaū wera tote mata hiato te hangarau tauhohenga tahi hei whakaranu i ngā tote e toru, ngā tote e rua me te hopi whakarewa i roto i te pūnaha tauhohenga me te rahi o te witi taiao tuatahi me ngā momo hinu whakahinuhinu hei whakarite i te marara katoa o te whakaū wera i roto i te pūnaha PVC, ā, i te wa ano, nā te whakakotahitanga me te hinu whakahinuhinu hei hanga i te āhua kirikiri, ka karohia hoki te paitini i puta mai i te puehu mata. Kei roto i ngā whakaū tote mata hiato ngā wāhanga whakaū wera me te hinu whakahinuhinu e hiahiatia ana mō te tukatuka, ā, e kiia ana ko ngā whakaū wera katoa. Ko ōna āhuatanga penei:

1. Paitini.

2. Kāore e taea te whakamahi mō ngā hua mārama.

3. He pai te ārai hiko me te ātete ki te huarere;

4. Utu iti;

5. He pai te mahi tukatuka e tika ana mō ngā momo tukanga;
