Ngā painga o ngā paipa PVC
1. Te Āhua o te Kawe: Ko te taumaha motuhake o te rauemi UPVC he kotahi whakatekau noa iho i te taumaha o te rino maka, ā, he iti ake te utu tuku me te tāuta.
2. He nui te ātete o te UPVC ki te waikawa me te kawakore, engari ko ngā waikawa kaha me ngā kawakore e tata ana ki te pūwāhi mātotoru, ngā matū whakapūkara kaha rānei i te kukū mōrahi.
3. Kāore e kawe hiko: Nā te mea kāore e kawe hiko te rauemi UPVC, ā, kāore e waikura ina pāngia e te iahiko, e te hiko rānei, kāore he hiahia mō tētahi atu tukatuka.
4. Kāore he āwangawanga mō te ārai ahi nā te mea kāore e taea te tahu, te whakatairanga rānei i te mura.
5. He māmā noa iho te tāutanga, ā, he iti hoki te utu nā te whakamahinga o te piripiri PVC, kua whakamātauhia tōna pono, tōna haumaru hoki, he ngāwari ki te whakamahi, ā, he iti hoki te utu. He tino māmā hoki te tapahi me te hono.
6. He tino ātete ki te huarere me te waikura huakita me te harore ka roa ai te mau o ngā mea katoa.
7. He iti te ātete me te tere rere tere: ka whakaitihia e te pakitara o roto maeneene te ngaronga o te wai, ka ārai i te piri o ngā paru ki te pakitara paipa maeneene, ā, ka māmā ake, ka iti ake hoki te utu o te tiaki.

Ehara te kirihou i te PVC.
He kirihou maha ngā mahi a te PVC, ka taea te whakamahi mō ngā momo mea maha, tae atu ki ngā taonga whare noa me ngā papa hanga.
I ngā wā o mua, ko te PVC te kirihou i whakamahia whānuitia i te ao, ā, he maha ngā whakamahinga. He whānuitia te whakamahinga i roto i ngā rauemi hanga, ngā taonga ahumahi, ngā mea e hiahiatia ana i ia rā, te hiako papa, ngā taera papa, te hiako hangai, ngā paipa, ngā waea me ngā taura, ngā kiriata takai, ngā pounamu, ngā muka, ngā rauemi pahuka, me ngā rauemi hiri, me ētahi atu mea.

I te 27 o Oketopa, 2017, i kohikohi tuatahitia e te Tari Rangahau Mate Pukupuku o te Whakahaere Hauora o te Ao tētahi rārangi o ngā matū whakaputa mate pukupuku, ā, ko te polyvinyl chloride tētahi o ngā momo matū whakaputa mate pukupuku e toru i runga i taua rārangi.
He pūmua kore-āhua me ngā tohu o te hanganga tioata, he pūmua te pūmua polyvinyl chloride e whakakapi ana i tētahi ngota chlorine mō tētahi ngota hauwai i roto i te polyethylene. Kua whakaritea tēnei tuhinga penei: n [-CH2-CHCl] Ko te nuinga o ngā monomer VCM ka honoa i roto i te whirihoranga pane-ki-te-hiku hei hanga i te pūmua rārangi e mōhiotia ana ko te PVC. Ka honoa ngā ngota waro katoa e ngā hononga, ā, kua whakaritea i roto i te tauira zigzag. He ranu sp3 tō ia ngota waro.

He poto te hanganga pūmau o te mekameka ngota PVC, he rite tonu te hononga-a-ira. Ka piki ake te hononga-a-ira i te hekenga o te pāmahana whakapūhui. He hanganga pūmau kei roto, tae atu ki te hanganga pane-ki-pane, mekameka peka, hononga takirua, allyl chloride, me te tuatoru o te chlorine i roto i te hanganga macromolecular polyvinyl chloride, ka hua ake he ngoikoretanga pēnei i te iti o te ātete ki te whakarerekētanga wera me te ātete ki te koroheketanga. Ka taea te whakatika i aua ngoikoretanga i muri i te āhua kua honoa.

Tikanga hononga PVC:
1. Ka whakamahia he kāpia motuhake hei hono i ngā hononga paipa PVC; me rūrū te kāpia i mua i te whakamahinga.
2. Me horoi te wāhanga o te pūwero me te paipa PVC. Mēnā he iti ake te mokowā i waenganui i ngā pūwero, he maeneene ake te mata o ngā hononga. Kātahi ka paraitia te kāpia ki roto i ia pūwero, ka paraitia kia rua ngā wā ki waho o ia pūwero. 40 hēkona i muri i te maroke, tangohia te kāpia, ā, kia aro ki te whakanui ake, ki te whakaiti rānei i te wā maroke i runga i te āhua o te rangi.
3. Me whakakī anō te paipa i muri i ngā hāora 24 i te hononga maroke, me tāuta te paipa ki roto i te awaawa, ā, kāore e whakaaetia kia mākū. I te wā e whakakī ana, tiakina ngā hononga, whakakīia te rohe e karapoti ana i te paipa ki te onepu, ā, whakakīia kia nui.
4. Hei hono i te paipa PVC ki te paipa maitai, horoia te hononga o te paipa maitai kua honoa, whakamahanahia kia ngawari ai te paipa PVC (me te kore e tahuna), kātahi ka whakaurua te paipa PVC ki roto i te paipa maitai kia whakamatao. Ka pai ake te hua mēnā ka whakauruhia he mowhiti i hangaia ki te paipa maitai.
Ngā paipa PVCka taea te hono i roto i tētahi o ngā huarahi e whā:
1. Mena kua pakaru nui te paipa, ko te katoapaipame whakakapi. Ka taea te whakamahi i tētahi hononga tauranga-rua hei mahi i tēnei.
2. Ka taea te whakamahi i te huarahi whakarewa hei aukati i ngā turuturu o te kāpia whakarewa. I tēnei wā, ka ringihia te wai o te paipa matua, ka puta he pēhanga kino i mua i te werohanga o te kāpia ki roto i te kōhao i te wāhi turuturu. Ka kumea te kāpia ki roto i ngā pūwero hei hua o te pēhanga kino o te paipa, ka aukati i te turuturu.
3. Ko te whāinga matua o te tukanga here o te ringaringa ko te turuturu o te anga i roto i ngā kapiti me ngā kōhao iti. Kua whiriwhiria te paipa rite tonu mō te tapahi roa, ā, ko te roa kei waenga i te 15 ki te 500 px. Ka honoa te mata o roto o te anga me te mata o waho o te paipa kua whakatikatikaina ki ngā hononga e ai ki te tukanga i whakamahia. Whai muri i te paninga o te kāpia, ka whakakorikoria te mata, kātahi ka piri pūmau ki te pūtake o te turuturu.
4. Hei hanga i tētahi otinga kapia mā te whakamahi i tētahi matū whakamaroke kapia epoxy, whakamahia te tikanga muka karāhe. Ka whatua kia ōrite ki runga i te mata o te paipa, i te hononga turuturu rānei i muri i te rumakina ki roto i te otinga kapia me te kakahu muka karāhe, ā, i muri i te whakamaroke, ka huri hei FRP.
