Kei te pōhēhē koe i ngā kupu whakarāpopoto kirihou katoa i roto i ngā putumōhio paipa? Mā te whiriwhiri i te rauemi hē pērā i te PP ina hiahiatia ana te PE ka raru pea te pūnaha me te utu nui mō ngā whakakapinga.

Ko te tikanga o te PP ko te Polypropylene. He polymer thermoplastic pakari, pakari, ā, he tino pakari. I roto i te ao o ngā paipa, he rongonui mō tōna ātete tino pai ki te wera me te whānuitanga o ngā matū, ā, he mea whakaoti rapanga mō ngā tono ahumahi uaua.

I Pntek, e whakapono ana mātou ki te whakamahi i ngā rauemi tika mō te mahi tika.Polypropyleneehara i te mea he kirihou noa iho; he otinga motuhake. Mō te tohunga mekameka tuku taonga pērā i a Carlos, he mea nui te mārama ki tēnei rerekētanga. Ina taea e ia te whakamārama ki tētahi kiritaki ahumahi he aha te PP anake te kōwhiringa mō ā rātouraina para matū, ehara i te mea ko te hoko hua anake tāna; kei te whakarato hoki ia i tētahi otinga haumaru, mō te wā roa, hei tiaki i ā rātou mahi.

He aha te paipa PP?

Ki tō whakaaro he rite tonu ngā paipa kirihou pakari katoa? He mōrearea tēnei whakaaro ina pāngia e te pāmahana teitei, e ngā wai waikura rānei, ina tere te pirau me te pakaru o te paipa paerewa.

He paipa tika, mārō te paipa PP, he mea hanga ki te Polypropylene. Ko ōna āhuatanga motuhake ko te pāmahana mahi tino teitei ki te whakataurite ki te PVC me te PE, me te ātete pai ki ngā waikawa, ki te kawakore, me ētahi atu matū waikura. Koinei te whiringa pai mō ngā mahi taumaha.

Kua hikoi au i roto i ngā whare hanga matū, ā, he waikura te hau. I roto i aua taiao, me hiahia koe ki ngā rauemi ka taea e koe te whakawhirinaki katoa.Paipa PPkoia taua rauemi. Mō ngā kiritaki a Carlos i roto i te hanga, i te tukatuka rānei, ko te pono o ngā paipa PP te tikanga o te haumaru mahi me te karo i ngā turuturu kino. He hua kounga teitei mō ngā tono kāore e taea te rahunga. Koia mātou e tohe ana kia whakamahia ngā kapia kounga teitei mō ā mātou pūnaha PP.

Kāore i te rite katoa ngā PP

Hei whiriwhiri i te paipa PP tika, me mōhio koe ki ōna momo rerekē. Ko ngā momo matua e toru ka tūtaki koe he mea hanga mō ngā mahi rerekē.

• PP-H (Homopolymer):
  Koinei te momo PP tino pakari. He kaha teitei tōna, ā, he tino ātete ki ngā matū. Ka kitea nuitia i roto i ngā wheketere tukatuka ahumahi me ngā wheketere matū.
• PP-B (Poraka Whakakotahi):
  He tāpiringa kei tēnei momo hei whakakaha ake i a ia, hei ātete hoki ki te pānga, inā koa i ngā pāmahana iti. He tino pai mō ngā paipa para ahumahi ka pakaru pea.
• PP-R (Kopaira Matapōkere):
  Koinei te mea tino ngāwari o ngā mea e toru, ā, koinei te paerewa mō ngā paipa wai wera me te wai matao i roto i ngā whare. He tino pai mō te whakahaere i te pēhanga mō te wā roa i ngā pāmahana tiketike.

He mea nui ki te kaiwhakahaere hoko te mōhio ki te momo hei pupuri. Tērā pea ka pupuri a Carlos i te PP-R mō āna kiritaki kaimahi paipa, me te PP-H mō āna kiritaki ahumahi.

He aha te whakamahinga o te PP?

Kei te whakamahi koe i tētahi paipa whānui mō tētahi mahi tino motuhake, uaua hoki? Nā tēnei kore taurite ka puta he turuturu, he poke te wai, ā, he nui te utu mō te pūnaha kia kore e mahi. Me whai taputapu motuhake koe.

Ka whakamahia ngā paipa PP i roto i ngā mahi e wera rawa ana, e waikura rawa ana rānei mō ngā kirihou noa pēnei i te PVC. Ko ōna whakamahinga matua ko te kawe matū ahumahi, te rerenga wai taiwhanga, ngā tipu maimoatanga wai para, me ngā raina wai wera me te matao i roto i ngā whare (ina koa ko te PP-R).

Mā ngā tono mō te PP ka kitea e koe te wāhi e kaha ai. I mua, i tukuna e mātou tētahi kaupapa mō tētahi wheketere tukatuka kai nui. I hiahiatia kia kawe i ngā wai horoi wera, paku waikawa. Kua ngohengohe te PVC, ā, kua waikura te konganuku. Ko te PP te otinga tino pai, he otinga roa. Ina taea e Carlos te tohu i ēnei whakamahinga motuhake, ka āwhina ia i ana kiritaki kia kite i te uara me te karo i te hē utu nui.

Ngā Wāhanga Matua o te Whakamahinga

He pai te PP mō ngā rauemi e uaua ana ki te whakamahi. Nā te huinga ahurei o ngā āhuatanga, he mea tino pai mō ngā momo rāngai matua.

Ahumahi/Taupānga	He aha i whakamahia ai te PP
Ngā Raina Matū Ahumahi	Ka taea e ia te kawe haumaru i te whānuitanga o ngā waikawa, ngā kawakore me ngā para ahumahi, me te kore e waikura, e pakaru rānei.
Ngā Paipa Wai Wera (PP-R)	Ka taea e ia te whakahaere i ngā pāmahana wai tae atu ki te 90°C (194°F) tonu, ā, kāore e hoatu he reka, he kakara rānei ki te wai inu.
Te Maimoatanga Wai Para	Ka ātete ki te ranunga matatini o ngā matū e kitea ana i roto i ngā wai para o ngā ahumahi me ngā wai para o ngā tāone, kia roa ai te ora ratonga, kia pono ai hoki.
Ngā Taiwhanga me te Hauora	E whakamahia ana mō ngā pūnaha waikeri e hiahia ana ki te whakahaere i ngā momo para matū me te kore e turuturu, e pirau rānei i roto i te wā.

Mā te mārama ki ēnei tono ka āwhina a Carlos me tana tīma hokohoko ki te tautuhi wawe i ngā kiritaki he raruraru ā rātou e kore nei e taea e ngā paipa PP anake te whakaoti.

He kaha ake te PP i te PVC?

Kei te whiriwhiri koe i te PVC mā te taunoa nā te mea he mea noa? He hapa nui tēnei ina whakamahia he wera, he matū motuhake rānei ki roto i tō pūnaha, ka pā te pakaru o ngā paipa me ngā turuturu morearea.

Kei te whakamāramatanga o te kupu "kaha ake" te tikanga. I te pāmahana rūma, he pakari ake te PVC. Heoi, he pai rawa atu te PP i ngā wāhanga matua e rua: ka taea e ia te tu atu ki ngā pāmahana teitei ake, ā, he kaha ake tōna pānga, arā, he iti ake te tūponotanga ka pakaru mēnā ka pāngia.

He pātai tēnei e rangona tonutia ana e au. Ehara te whakautu i te mea ko tēhea te mea pai ake i te katoa, engari ko tēhea te mea tika mō te āhuatanga motuhake. Ko tāku mahi he whakarite kia mōhio ō mātou hoa mahi, pērā i a Carlos. Ina pātai mai tētahi kaihoko ki a ia i tēnei pātai, kāore e taea e ia te whakautu mā te "āe" me te "kāo" noa iho, engari mā te tohutohu a te tohunga hei āwhina i a rātou ki te whiriwhiri i te paipa tino tika, hei hanga i tōna ingoa hei kaiwhakarato pono.

He Whakataurite Upoko-ki-Upoko

Āhuatanga	PP (Poroporoperene)	PVC (Polyvinyl Chloride)
Te pāmahana mōrahi	Tino pai, tata ki te 90°C (194°F)	Kāore i te pai, tata ki te 60°C (140°F) anake
Ātete Matū	He tino pai, inā koa mō ngā waikawa me ngā kawakore.	He pai, engari ka taea te pakaru e ētahi matū pēnei i ngā whakarewa.
Te Kaha o te Pānga	Tino pai. He pakari, ā, he iti ake te tūponotanga kia pakaru.	Pai. He tino pakari, ā, ka pakarukaru pea.
Tikanga Hononga	Te Whakarewatanga Wera (whakapiri). Ka waihanga i tētahi hononga tuturu, kore hononga.	Sima whakarewa (piripiri) ngā gasket rānei.
Utu	Te utu tīmatanga teitei ake mō ia paipa/whakaurunga.	Te utu tīmatanga iti iho.

Nō reira, mō te paipa whakamakuku wai matao, he kōwhiringa pai, he kōwhiringa utu-pai te PVC. Engari mō te paipa wai wera i roto i te wheketere, i te waikeri matū rānei i roto i te taiwhanga, ko te PP anake te kōwhiringa haumaru me te pono. Mā te utu tāpiri ka hokona he haumaru me te roa ake o te ora ratonga.

Me pēhea te hono i ngā paipa PP?

Kei te āwangawanga koe kei puta tuatahi mai he turuturu i ngā hononga o tō pūnaha paipa? Mō ngā paipa PP, he tino kino te whakamahi i te kāpia, i ngā rawhi rānei.

Ka honoa ngā paipa PP mā te whakamahi i te whakarewa wera. Ka whakamahia he taputapu motuhake hei whakarewa i te mata o te paipa me te hononga, kātahi ka panaia ngātahi. I a rātou e whakamatao ana, ka honoa hei wahi kirihou kotahi, pumau, ā, kāore e turuturu.

Ko te hononga te wāhanga tino nui o tētahi pūnaha paipa. Ki taku whakaaro, ko te tikanga hanumi wera e whakamahia ana mō te PP te hononga pono rawa atu. Ka whakakorea ngā ngoikoretanga o ngā kāpia ka taea te pirau, ngā hiri miihini rānei ka taea te wetewete. Mō ngā kiritaki kirimana a Carlos, ko te tikanga tēnei he rangimarie o te hinengaro. Ka taea e rātou te tāuta i tētahi pūnaha PP, te whakamātautau, me te mōhio he kaha, he pakari hoki ngā hononga pērā i te paipa tonu.

Ngā Tikanga Whakakotahi Matua e Rua

E rua ngā tikanga matua mō te whakarewa PP, ā, ko te tikanga e whakamahia ana e koe ka whakawhirinaki ki te rahi o te paipa.

• Socket Fusion:
  Koinei te tikanga tino noa mō ngā paipa iti ake te diameter, tae atu ki te 125mm (tata ki te 4 inihi). He taha tāne, he taha wahine hoki tō tētahi taputapu whakamahana motuhake. Ka whakamahanahia te taha o waho o te pito paipa me te taha o roto o te putanga whakauru i te wā kotahi. Kātahi ka tangohia te taputapu ka panaia te paipa ki roto i te whakauru. Ka hangaia he hononga tino kaha, he ma te āhua.
• Whakakotahitanga o te Pūtu:
  Mō ngā paipa nunui ake, koinei te tikanga paerewa. Ka puritia ngā pito tapawhā o ngā paipa e rua (he paipa me te hononga rānei) ki roto i tētahi mīhini nui. Ka whakatakotoria he pereti whakamahana ki waenganui i a rāua, ka whakarewahia ngā pito e rua. Ka tangohia te pereti, ā, ka pēhia e te mīhini ngā pito rewa kia kotahi, ka hangaia he poroporo pakari huri noa i te taha o waho o te paipa. Ka hangaia e tēnei tikanga he roto maeneene tino pai, he mea pai mō te rere.

Ka hangaia e ngā tikanga e rua he hononga pumau e kore e turuturu.

Whakamutunga

He paipa motuhake te PP, te Polypropylene rānei, mō ngā mahi wera nui me ngā mahi matū. He kaha ake i te PVC i roto i ēnei āhuatanga, ā, ka honoa e te hanumi wera tuturu, ka hangaia he pūnaha tino pono.
