Kei te hoahoa koe i tētahi pūnaha paipa wai wera, engari nā te āwangawanga mō ngā turuturu ka ara ake koe i te pō. Mā te whakamahi i ngā rauemi hē ka pakaru pea ngā paipa, ka nui te utu mō te kino o te wai, ka pakaru hoki tō ingoa pai.
Ko ngā hononga PPR he hononga e whakamahia ana i roto i ngā pūnaha paipa, he mea hanga mai i te Polypropylene Random Copolymer. He mea hanga ēnei mō te kawe wai wera me te wai matao, ā, ka honoa mā te hanumi wera, ka hanga he hononga pumau, he hononga maeneene, ā, kāore e turuturu i waenganui i te paipa me te hononga.
Ina kōrero ahau ki ngā hoa mahi pērā i a Budi i Initonīhia, ka huri te kōrero ki te pono mō te wā roa. Ko ana kiritaki, ahakoa kei te hanga hōtēra hou, kei te hanga whare whānau rānei, e hiahia ana ki tētahi pūnaha paipa ka taea e rātou te tāuta me te wareware. Kāore e taea e rātou te utu i ngā turuturu. Koinei te wāhi eNgā pūnaha PPRkanapa. Ko te tikanga honohono, arā, ko te hanumitanga wera, kāore e whakamahi i te kāpia, i ngā gasket rānei. Ka hurihia te paipa me te hononga hei wahi kirihou kotahi, tonu. Nā tēnei āhuatanga ahurei i noho ai te PPR hei paerewa koura mō ngā pūnaha wai wera me te wai matao huri noa i te ao.
He aha te whakaurunga PPR?
Ka kite koe i te "PPR" i roto i te rārangi hua, engari kāore koe i te tino mōhio he aha te mea e rerekē ai. Ki te kore koe e mōhio ki ngā kaupapa matua, kāore e taea e koe te whakamārama maia i tōna uara ki tō rōpū, ki ō kiritaki rānei.
He hononga paipa te hononga PPR i hangaia ki te kirihou motuhake e kiia nei ko te Polypropylene Random Copolymer. Ka whakamahia hei hono i ngā paipa PPR, ā, ko tōna āhuatanga matua ko te tikanga whakarewa wera e hanga ana i tētahi hononga pumau, kāore he turuturu.
Me wehewehe tātou.Polypropylene"ko te kirihou turanga, engari ko te "Copolymer Matapōkere"Ko tētahi wāhanga te mea ngaro. Ko te tikanga ka whakaranua e mātou tētahi atu monomer i te wā e hangaia ana, ka pakari ake te kirihou, ā, ka pai ake te whakahaere i te wera ki te polypropylene paerewa. Heoi, ko te mea nui ko te āhua o tā rātou hononga. Ka whakamahia e koe he taputapu whakamahana motuhake hei whakarewa i te roto o te hononga me te waho o te paipa i te wā kotahi. Kātahi ka pana noa i a rātou. Ina mātao, kua honoa ngā ngota kirihou hei wahi totoka kotahi. Mā tēnei ka hangaia te wāhanga tino kaha o te paipa katoa, ka whakakorea te mōrearea o ngā turuturu hononga mō ake tonu atu.
Ngā Momo Pūrere PPR Noa
| Momo Whakauru | Mahi |
|---|---|
| Hononga/Pūhono | Ka honoa ngā paipa e rua ki te rārangi tika. |
| Tuke (90° me te 45°) | Ka whakarerekē i te ahunga o te rere o te paipa. |
| Tī | Ka wehea te rere kia rua ngā taha (āhua-T). |
| Kaiwhakaiti | Ka hono i tētahi paipa nui ki tētahi paipa iti iho. |
| Taupoki Mutunga | Ka hiritia te pito o te paipa. |
| Uniana | Ka taea te momotu ngāwari i ngā paipa mō te mahi tiaki. |
He pai ake ngā hononga PPR i te PVC?
Kei ngā wāhi katoa te PVC, ā, he iti te utu, nō reira ka whakaaro koe he aha koe ka utu nui ake ai mō te PPR. Mēnā ka hē te whiriwhiri i tētahi mō te paipa wai wera, ka raru pea te paipa ina pakaru.
Mō te wai wera, he pai ake te PPR i te PVC. He mea hanga motuhake te PPR kia tu ki ngā pāmahana tae atu ki te 95°C. Kaua te PVC paerewa e whakamahia mō ngā pāmahana neke atu i te 60°C, nā reira kāore e pai, e kore hoki e haumaru mō ngā paipa wai wera.
Koinei te pātai e tino pā ana ki ahau, ā, ko te whakautu he mea e pā ana ki te whakamahi i te taputapu tika mō te mahi. Kāore koe e whakamahi i te hama hei huri i te tīwiri. Waihoki, kaua e whakamahi i te PVC mō te wai wera. Ka ngawari te PVC, ā, ka taea te huri i raro i te pēhanga i ngā pāmahana teitei. He mea hanga te PPR mō tēnei. Ka taea e tōna hanganga ngota te whakahaere i te wera me te pēhanga me te kore he raruraru. Mō ngā raina tuku wai matao,PVCHe kōwhiringa pai, he kōwhiringa utu-pai hoki. Engari mō ngā tono katoa e pā ana ki te wai wera, mai i te kaukau kāinga māmā ki te tukanga ahumahi uaua, ko te PPR anake te kōwhiringa haumaru me te pono. Koia ahau ka tohutohu tonu i a Budi kia tukuna ngā mea e rua engari kia tino mārama ki ana kiritaki te wāhi hei whakamahi i ia mea.
PPR me te PVC: Ngā Rerekētanga Matua
| Āhuatanga | PPR (Polypropylene Matapōkere Copolymer) | PVC (Polyvinyl Chloride) |
|---|---|---|
| Te Whakamahinga Wai Wera | Tino pai.Kua whakatauria te pāmahana tae atu ki te 95°C. | Kāore.Kāore i te haumaru mō te wai wera (tae atu ki te 60°C te pāmahana). |
| Tikanga Hononga | Te Whakakotahitanga Wera (Te Whakarewa) | Sima Whakarewa (Pīpiri) |
| Te Kaha o te Hononga | Ka huri hei wahi kotahi, he tino kaha. | He here piri, ka ngoikore haere i roto i te wā. |
| Ngāwari | He ngāwari ake, he iti ake te tūponotanga kia pakaru. | He pakari, he pakarukaru, ka pakarukaru ina pā. |
| Pai rawa atu mō | Ngā pūnaha wai inu wera me te matao. | Wai matao, rerenga wai, whakamakuku. |
Ko tēhea te mea pai ake, PPR, HDPE rānei?
He kaupapa nui tāu, ā, e kite ana koe i ngā kōwhiringa PPR me HDPE. He kirihou whakarewa ēnei e rua, nō reira kāore koe i te tino mōhio ko tēhea te kōwhiringa tika mō tō tono.
Kāore tetahi o ēnei i te pai ake i te nuinga; he rerekē ngā mahi i hangaia ai. He pakari ake te PPR, ā, koinei te toa mō ngā paipa wai wera me te wai matao o roto. He ngāwari ake te HDPE, ā, he ātete ki te UV, he mea tino pai mō ngā paipa wai nui o waho.
Whakaarohia pēnei: Ko te PPR mō ngā uaua me ngā uaua toto i roto i te whare, ko te HDPE ia mō ngā raina matua e rere ana ki te whare. He painga te pakari o te PPR i roto i te whare nā te mea ka taea te rere paipa tika, ātaahua hoki, he āhua ngaio, he ngāwari hoki te tautoko.HDPEHe tino ngāwari ake te whakamahi i te Polyethylene Matotoru-Teitei. Mā tēnei ka taea te tuku i roto i ngā koiri roa me te neke haere i ngā arai i raro i te whenua, ka whakaiti i te maha o ngā hononga e hiahiatia ana. He mangu hoki nā te mea kei roto he pango waro, e tiaki ana i a ia mai i te pirau o te rā (UV). Kāore koe e whakamahi i te PPR mō te pūtake i raro i te whenua, ā, kāore koe e whakamahi i te HDPE mō te raina wai wera ki te kaukau. He tohunga rātou e tino matatau ana i roto i ō rātou ake taiao.
PPR vs. HDPE: Arotahi ki te Taupānga
| Āhuatanga | PPR | HDPE |
|---|---|---|
| Whakamahinga Matua | Ngā paipa wai wera me te wai matao o roto. | Ngā paipa wai o waho o raro whenua, ngā raina hau. |
| Ngāwari | Āhua-pakari. | He tino ngāwari, e wātea ana i roto i ngā koiri. |
| Ātete UV | Iti (me tiaki mai i te rā). | Tino pai (he parenga te pango waro). |
| Tae | He kakariki, he mā rānei te nuinga. | Ko te tikanga he pango, he kikorangi rānei. |
| Whakatauranga Pēhanga | Teitei (hei tauira, PN20, PN25). | Ka rerekē i runga i te akomanga (hei tauira, PE100). |
Ko tēhea te mea pai ake, PPR, PEX rānei?
Ka kite koe i te PEX e whakamahia ana i ngā papa mahi maha nā te mea he ngāwari, he tere hoki te tāuta. Mā tēnei ka whakaaro koe mēnā he hangarau tawhito te PPR, mēnā kei te mau tonu he painga.
Kei tō hiahia te kōwhiringa. He ngāwari ake te PEX, ka taea te tere ake te tāutanga me te iti ake o ngā hononga. Ka whakamahia e te PPR ngā hononga totoka, wera-whakamahana e kiia ana he pono ake i ngā hononga kume miihini e whakamahia ana mō te PEX.
PEX (Polyethylene Hono-whiti)He hua tino pai, ā, ko tōna painga matua ko te ngāwari. Ka taea e koe te piko i te paipa PEX ki ngā kokonga, ka whakaiti i te hiahia mō ngā hononga tuke. Heoi, ko tōna ngoikoretanga ko ngā hononga tonu. Ka whakawhirinaki ngā pūnaha PEX ki ngā hononga miihini, pērā i ngā mowhiti whakapiko whakarewa, ngā rawhi rānei, hei whakau i te paipa. I roto i ngā tau maha, ka taea e ēnei wāhanga whakarewa te waikura, te wetewete rānei, ka puta ai he wāhi turuturu pea. Ko teNgā painga o te pūnaha PPRko te whakarewa honohono. Ka whakakorea katoatia te tūponotanga o te pakaru o te hononga. Waihoki, he maha ngā wā ka uru ngā hononga PEX ki roto i te paipa, ka whakaiti i te diameter o roto, ā, ka ārai i te rere o te wai. He hononga honohono ngā hononga PPR, ka mau tonu te ara rere katoa, kāore he arai. Ki a mātou, ko te haumaru tino o te hononga whakarewa ka waiho te PPR hei whiringa pai rawa atu mō ngā kaupapa hanga whare roa.
PPR me PEX: He Whakataurite
| Āhuatanga | PPR | PEX |
|---|---|---|
| Ngāwari | Paipa mārō-haurua. | Paipa tino ngāwari. |
| Pūnaha Hononga | Te Whakakotahitanga Wera (Te Whakarewa) | Mīhini (Ngā Kutikuti, Ngā Āpiti) |
| Te Pono o te Hononga | Hei wāhanga tonu o te paipa. | Ka whakawhirinaki ki te kounga o te taputapu me te whakaurunga. |
| Ngā taputapu | Ngā pūwero (kāore he herenga rere). | Ngā whakaurunga (ka taea te whakawhāiti i te rere). |
| Ngā Utauta e Hiahiatia ana | Mīhini whakarewa wera. | He taputapu whakakī, he taputapu whakapiri rānei. |
Whakamutunga
Ngā taputapu PPRKoinei te otinga tino pai mō ngā paipa wai wera me te wai matao pono. Ka hangaia e ngā hononga wera he pūnaha ātete turuturu, e tuku ana i ngā painga mārama o te roa me te haumaru mō tetahi kaupapa hanga whare.
