Kua pōhēhē koe i ngā kōwhiringa whakauru kirihou katoa? Mā te whiriwhiri i tētahi mea hē ka roa pea te mahi, ka turuturu, ka nui hoki ngā utu whakatikatika. Ko te mārama ki ngā whakauru PP te mea nui ki te whiriwhiri i te wāhanga tika.

Ngā taputapu PPHe hononga i hangaia mai i te polypropylene, he kirihou wera pakari, he maha hoki ngā whakamahinga. Ko te nuinga o ēnei e whakamahia ana hei hono i ngā paipa i roto i ngā pūnaha e hiahia ana kia nui te ātete ki te wera me te ātete pai ki ngā matū, ā, he mea tino pai mō ngā tono ahumahi, taiwhanga, me te wai wera.

Nō nā tata nei ka waea atu ahau ki a Budi, he kaiwhakahaere hoko i Initonīhia. He tohunga ia ki te PVC engari he kiritaki hou tāna e tono ana mō "Ngā hononga kōpeketanga PP"mō te whakahoutanga taiwhanga. Kāore a Budi i tino mōhio ki ngā rerekētanga matua me te wā e taunaki ai i te PP hei utu mō te PVC e mōhio pai ana ia. I āwangawanga ia kei hoatu he tohutohu hē. He mea noa tēnei āhuatanga. He maha ngā tohunga e mōhio ana ki tētahi, ki ētahi momo rauemi paipa engari he nui rawa atu te whānuitanga o ngā kirihou. Ko te mōhio ki ngā kaha motuhake o ngā rauemi pēnei i te polypropylene te mea e wehewehe ana i te kaihoko noa mai i te kaiwhakarato otinga. Me wehewehe tātou he aha te mea e tino nui ai ngā taputapu PP i roto i ngā paipa hou.

He aha te hononga PP?

Me hono e koe ngā paipa mō tētahi mahi uaua, engari kāore koe i te tino mōhio mēnā ka taea e te PVC te whakahaere. Mā te whakamahi i te rauemi hē ka kore e taea te pakaru o te pūnaha, ka nui hoki te utu mō te mahi anō.

He hononga te hononga PP i hangaia mai i te kirihou polypropylene. Ko ōna āhuatanga matua ko te pumau i te pāmahana teitei (tae atu ki te 180°F, 82°C rānei) me te ātete pai ki ngā waikawa, ki ngā kawakore, me ētahi atu matū waikura, koia te take i whiriwhiria ai i runga ake i te PVC paerewa i roto i ngā taiao motuhake.

Ina tirohia tata atu he hononga PP, ko ngā āhuatanga o te polypropylene tonu te mea e tirohia ana e tātou. He rerekē kiPVC, ka pakarukaru pea i ētahi matū, ka rerekē rānei i ngā pāmahana teitei ake, ka mau tonu te hanganga o te PP. Nā tēnei ka waiho hei rauemi matua mō ngā mea pēnei i ngā raina para matū i roto i te taiwhanga whare wānanga, i ngā porowhita tohanga wai wera rānei i roto i te whare arumoni. I whakamārama ahau ki a Budi ahakoa ko te PVC meNgā taputapu PPHei hono i ngā paipa, he rerekē rawa ā rātou mahi. Ka whakamahia e koe te PVC mō ngā paipa wai matao whānui. Ka whakamahia e koe te PP ina uru te wera, ngā matū rānei. I mārama tonu ia. Ehara i te mea ko tēhea te "pai ake," engari ko tēhea tetaputapu tikamō te mahi motuhake e hiahiatia ana e tana kiritaki.

Ngā Hononga PP me ngā Hononga PVC: He Whakataurite Tere

Hei whakamārama ake i te kōwhiringa, anei tētahi whakamārama māmā mō te hiranga o ia rauemi.

He aha te tikanga o te kupu PP i roto i ngā paipa?

Ka kite koe i ngā reta "PP" i roto i te rārangi hua, engari he aha te tikanga mō tō pūnaha? Mā te kore aro ki ngā waehere rauemi ka taea e koe te hoko i tētahi hua kāore e tika ana.

I roto i ngā paipa, ko te PP te tohu mō te Polypropylene. Koinei te ingoa o te polymer thermoplastic e whakamahia ana hei hanga i te paipa, i te hononga rānei. Mā tēnei tapanga ka kitea he pakari, he ātete ki ngā matū, he pai hoki te mahi i ngā pāmahana teitei, e wehewehe ana i a ia mai i ētahi atu kirihou pērā i te PVC, te PE rānei.

Ko te Polypropylene he wāhanga o tētahi whānau rauemi e kiia nei kongā kirihou wera. I roto i ngā kupu māmā, ko te tikanga ka taea e koe te whakamahana kia rewa, te whakamatao, kātahi ka whakamahana anō me te kore e tino pakaru. Mā tēnei āhuatanga ka māmā ake te hanga ki ngā āhua uaua pēnei i ngā hononga tī, ngā tuke, me ngā urutau mā te werohanga pokepoke. Mō te kaiwhakahaere hoko pēnei i a Budi, ko te mōhio ki te "PP" ko te tikanga ko te polypropylene te taahiraa tuatahi. Ko te mahi e whai ake nei ko te mārama he rerekē ngā momo PP. Ko ngā mea e rua e tino kitea ana koPP-H(Homopolymer) me te PP-R (Random Copolymer). He pakari ake te PP-H, ā, he maha ngā whakamahinga ahumahi e whakamahia ana. He ngāwari ake te PP-R, ā, koinei te paerewa mō ngā pūnaha paipa wai wera me te wai matao i roto i ngā whare. Mā tēnei mōhiotanga ka āwhina ia ki te pātai pai ake i ana kiritaki kia whiwhi ai rātou i te hua tika e hiahiatia ana e rātou.

Ngā momo Polypropylene i roto i ngā Paipa

He aha te paipa PP?

Me whai paipa koe mō te wai wera, mō te raina matū rānei, ā, me karo hoki i te waikura o te konganuku. Mēnā ka hē te whiriwhiri i te rauemi paipa, ka pāngia pea koe e te paru, ka turuturu, ka poto hoki te ora o te paipa.

He ngongo te paipa PP i hangaia mai i te kirihou polypropylene, i hangaia mō te kawe haumaru i ngā wai wera, te wai inu, me ngā momo matū. He mama, kāore e waikura, ā, he maeneene te mata o roto e ātete ana ki te hanga unahi, kia mau tonu ai te rere o te wai i roto i te wā.

Ka whakamahia ngā paipa PP me ngā hononga PP hei hanga i tētahi pūnaha tino ōrite. Ko tētahi o ngā painga nui ko te āhua o te hononga. Mā te whakamahi i tētahi tikanga e kiia nei kowhakarewa wera, ka whakamahanahia te paipa me te hononga, ā, ka honoa ngātahi kia mau tonu. Ka hangaia he mea totoka,hononga ātete turuturuhe rite te kaha ki te paipa tonu, e whakakore ana i ngā ngoikoretanga e kitea ana i roto i ngā pūnaha whakapiri (PVC) me ngā pūnaha miro (whakarewa). I mahi tahi ahau me tētahi kiritaki i tētahi whare tukatuka kai hou. I whiriwhiria e rātou he whare katoaPūnaha PP-Rmō ā rātou paipa wai wera me te horoi. He aha ai? Nā te mea kāore e taea e te rauemi te tuku i ngā matū ki roto i te wai, ā, nā ngā hononga kua honoa, kāore he kapiti mō te tipu o ngā huakita. Nā tēnei i whakamana te parakore o ā rātou hua me te haumaru o ā rātou tukanga. Mō rātou, ko ngā painga o ngā paipa PP i tua atu i ngā mahi putorino noa iho; he mea whakahaere kounga.

He aha ngā hononga PB?

Ka rongo koe i ngā hononga PB, ka whakaaro koe mēnā he huarahi kē atu ēnei hei whakakapi i te PP. He hapa nui te whakapoauau i ēnei rauemi e rua, nā te mea kua roa te tangata e pakaru whānuitia ana.

Ko ngā hononga PB he hononga mō ngā paipa Polybutylene (PB), he rauemi paipa ngāwari i whakamahia i mua mō ngā paipa whare. Nā te nui o te pakaru mai i te pakaru matū, kāore ngā paipa PB me ōna hononga e whakaaetia ana e te nuinga o ngā ture paipa, ā, e kiia ana he tawhito, he kore pono hoki.

He kaupapa nui tēnei mō te mātauranga mō te hunga katoa o te umanga. Ahakoa he rauemi hou, pono hoki te PP (Polypropylene), ko te PB (Polybutylene) ko tōna mua he raruraru. Mai i te tekau tau atu i 1970 ki te tekau tau atu i 1990, i whānuitia te tāutanga o te PB mō ngā raina wai wera me te matao. Heoi, i kitea ko ngā matū noa i roto i te wai ā-rohe, pērā i te chlorine, i whakaeke i te polybutylene me ōna hononga kirihou, ā, ka pakarukaru. Nā tēnei i hua ake ai ngā pakaru ohorere me ngā turuturu kino, ā, ka pakaru te wai i ngā piriona tāra puta noa i ngā whare maha. Ina whiwhi a Budi i tētahi tono mō ngā hononga PB i ētahi wā, ko te tikanga he whakatikatika. Kua whakangungua ia e au ki te tohutohu tonu i te kiritaki mō ngā mōrearea o te pūnaha PB katoa, me te taunaki i tētahi whakakapinga katoa ki tētahi rauemi pumau, hou pērā iPP-R or PEXEhara i te mea he nui ake ngā hoko; engari he mea hei tiaki i te kiritaki mai i te hinganga a meake nei.

Polypropylene (PP) vs. Polybutylene (PB)

Whakamutunga

Ko ngā hononga PP, he mea hanga mai i te polypropylene pakari, te mea pai mō ngā pūnaha wai wera me ngā pūnaha matū. He otinga hou, pono hoki ēnei, he rerekē ki ngā rauemi tawhito kua pakaru, pērā i te polybutylene.
