Pilikia e nā koho hoʻopili plastik āpau? ʻO ke koho ʻana i ka mea hewa hiki ke alakaʻi i ka lohi o ka papahana, nā leak, a me ka hoʻoponopono ʻana i ke kumu kūʻai. ʻO ka hoʻomaopopo ʻana i nā pono PP he kī nui i ke koho ʻana i ka ʻāpana kūpono.
ʻO nā mea hoʻopili PP nā mea hoʻohui i hana ʻia mai ka polypropylene, kahi thermoplastic paʻakikī a versatile. Hoʻohana mua ʻia lākou e hoʻohui i nā paipu i nā ʻōnaehana e koi ana i ka hoʻomanawanui wela kiʻekiʻe a me ke kūpaʻa maikaʻi ʻana i nā kemika, e hoʻolilo iā lākou i mea kūpono no ka ʻoihana, keʻena hana, a me nā noi wai wela.
Ua kelepona mai nei au me Budi, he luna kuai ma Indonesia. He loea ʻo ia i ka PVC akā he mea kūʻai hou aku e noi ana no “ʻO nā mea hoʻopili hoʻopili PP"no ka hoʻoponopono hou ʻana. ʻAʻole maopopo ʻo Budi i nā ʻokoʻa koʻikoʻi a i ka manawa e ʻōlelo ai iā PP ma luna o ka PVC ua ʻike maikaʻi ʻo ia. Ua hopohopo ʻo ia i ka hāʻawi ʻana i ka ʻōlelo aʻo hewa ʻole. He mea maʻamau kona kūlana. Ua kamaʻāina nui nā poʻe loea i hoʻokahi a ʻelua ʻano mea paipu akā ʻike i ka nui o nā plastics nui loa. he mea koʻikoʻi i ka paipu wai hou.
He aha ke ʻano o ka PP?
Pono ʻoe e hoʻohui i nā paipu no kahi hana koʻikoʻi, akā ʻaʻole ʻoe maopopo inā hiki iā PVC ke mālama. ʻO ka hoʻohana ʻana i ka mea hewa e alakaʻi i ka hemahema o ka ʻōnaehana a me ka hana hou ʻana.
ʻO kahi hoʻopili PP he ʻāpana pili i hana ʻia mai ka plastic polypropylene. ʻO kāna mau hiʻohiʻona nui ke kūpaʻa wela kiʻekiʻe (a hiki i 180 ° F a i ʻole 82 ° C) a me ke kūpaʻa kiʻekiʻe i nā waikawa, alkalis, a me nā kemika corrosive ʻē aʻe, ʻo ia ke kumu i koho ʻia ai ma luna o PVC maʻamau i nā wahi kikoʻī.
Ke nānā pono mākou i kahi kūpono PP, ke nānā pono nei mākou i nā waiwai o ka polypropylene ponoʻī. ʻAʻole likePVC, hiki ke lilo i palupalu me kekahi mau kemika a i ʻole deform i nā mahana kiʻekiʻe, mālama ʻo PP i kona kūpaʻa. ʻO ia ka mea e hele ai i nā mea e like me nā laina ʻōpala kemika ma ke keʻena o ke kulanui a i ʻole nā loulou kahe wai wela ma kahi hale kūʻai. Ua wehewehe au iā Budi ʻoiai ʻo PVC a meʻO nā lako PPhoʻohui i nā paipu, ʻokoʻa loa kā lākou hana. Hoʻohana ʻoe i ka PVC no ka paipu wai anuanu maʻamau. Hoʻohana ʻoe i ka PP ke komo ka wela a i ʻole kemika. Hoʻomaopopo koke ʻo ia. ʻAʻole ia e pili ana i ka "ʻoi aku ka maikaʻi," akā ʻo ia kamea hana ponono ka hana kiko'ī e pono ai i kāna mea kūʻai ke hana.

He aha ka manaʻo o ka PP i ka paipu?
ʻIke ʻoe i nā leka "PP" i loko o kahi waihona huahana, akā he aha ke ʻano o ia mau mea no kāu ʻōnaehana? ʻO ka nānā ʻole ʻana i nā code waiwai hiki ke alakaʻi iā ʻoe e kūʻai i kahi huahana kūpono ʻole.
I ka paipu, ʻo PP ka Polypropylene. ʻO ia ka inoa o ka polymer thermoplastic i hoʻohana ʻia e hana i ka paipu a kūpono paha. Hōʻike kēia lepili iā ʻoe ua kūkulu ʻia ka huahana no ka lōʻihi, ke kūpaʻa kemika, a me ka hana ʻana i nā mahana kiʻekiʻe, e hoʻokaʻawale iā ia mai nā plastics ʻē aʻe e like me PVC a i ʻole PE.
ʻO ka polypropylene kahi ʻāpana o ka ʻohana mea i kapa ʻianā mea wela. Ma nā huaʻōlelo maʻalahi, ʻo ia ke ʻano hiki iā ʻoe ke hoʻomehana iā ia a hiki i kahi helu heheʻe, hoʻomaʻalili, a laila hoʻomaʻamaʻa hou iā ia me ka ʻole o ka pōʻino nui. He mea maʻalahi kēia waiwai i ka hana ʻana i nā ʻano paʻakikī e like me nā tee-fittings, elbows, a me nā mea hoʻololi ma o ka hoʻoheheʻe ʻana. No ka luna kūʻai e like me Budi, ʻo ka ʻike "PP" ʻo ia ka polypropylene ka hana mua. ʻO ka mea aʻe ka hoʻomaopopo ʻana aia nā ʻano like ʻole o ka PP. ʻO nā mea maʻamau ʻeluaPP-H(Homopolymer) a me PP-R (Random Copolymer). ʻOi aku ka paʻakikī o PP-H a hoʻohana pinepine ʻia no nā noi ʻoihana. ʻOi aku ka maʻalahi o ka PP-R a ʻo ia ka maʻamau no nā ʻōnaehana paipu wai wela a me ke anuanu i nā hale. Kōkua kēia ʻike iā ia e nīnau i kāna mau mea kūʻai aku i nā nīnau maikaʻi aʻe e hōʻoia i ka loaʻa ʻana o ka huahana pololei a lākou e pono ai.
Nā ʻano o ka Polypropylene ma ka Paipu
| ʻAno | Inoa piha | ʻAno kī | Hoʻohana maʻamau |
|---|---|---|---|
| PP-H | Polypropylene Homopolymer | ʻOoleʻa kiʻekiʻe, ikaika | ʻO ka paipu kaʻina hana ʻoihana, nā pahu kemika |
| PP-R | Polypropylene Random Copolymer | Hiki ke hoʻopaʻa i ka wela no ka wā lōʻihi | Pūnaehana wai wela a me anu, paipu |
He aha ka paipu PP?
Pono ʻoe i kahi paipu no kahi wai wela a i ʻole laina kemika a makemake ʻoe e pale i ka ʻino o ka metala. ʻO ke koho ʻana i ka mea paipu hewa hiki ke alakaʻi i ka haumia, nā leaks, a me ke ola pōkole.
ʻO ka paipu PP he paipu i hana ʻia mai ka plastic polypropylene, i hoʻolālā ʻia no ka lawe ʻana i nā wai wela, ka wai inu, a me nā kinikona like ʻole. He māmā, ʻaʻole ʻino, a hāʻawi i kahi ʻili i loko e pale i ke kūkulu ʻana i ka unahi, e hōʻoia i ka kahe mau ʻana i ka manawa.
Hoʻohana ʻia nā paipu PP me nā mea pono PP e hana i kahi ʻōnaehana holoʻokoʻa. ʻO kekahi o nā pōmaikaʻi nui loa ke ʻano o ka hui ʻana. Ke hoʻohana nei i kahi ʻano i kapa ʻiahoʻoheheʻe wela, ua wela ka paipu a me ka paipu a hui mau. Hoʻokumu kēia i kahi paʻa,ami leak-proofʻo ia ka ikaika e like me ka paipu ponoʻī, e hoʻopau ana i nā wahi nāwaliwali i loaʻa i loko o nā ʻōnaehana glued (PVC) a i ʻole threaded (metal). Ua hana au me kekahi mea kūʻai ma kahi hale hana meaʻai hou. Ua koho lākou i kahi pihaʻōnaehana PP-Rno kā lākou wai wela a me nā laina hoʻomaʻemaʻe. No ke aha mai? No ka mea, ʻaʻole hiki ke hoʻokuʻu ʻia ke kino i loko o ka wai, a ʻo ka hui pū ʻana, ʻaʻohe māwae no ka ulu ʻana o ka maʻi bacteria. Ua hōʻoia kēia i ka maʻemaʻe o kā lākou huahana a me ka palekana o kā lākou hana. No lākou, ʻoi aku ka maikaʻi o ka paipu PP ma mua o ka paipu maʻalahi; he mea ia o ka hoomalu maikai.
He aha nā lako PB?
Lohe ʻoe e pili ana i nā pono PB a noʻonoʻo inā he koho lākou i ka PP. ʻO ka huikau ʻana i kēia mau mea ʻelua hiki ke hana hewa nui, no ka mea he moʻolelo o ka hāʻule ākea.
ʻO nā mea hoʻopili PB nā mea hoʻohui no nā paipu Polybutylene (PB), kahi mea maʻalahi o ka paipu maʻamau i maʻa mau no ka paipu hale. Ma muli o ke kiʻekiʻe o ka hāʻule ʻana mai ka haʻihaʻi kemika, ʻaʻole ʻae ʻia ka paipu PB a me kāna mau mea pono e ka hapa nui o nā code plumbing a manaʻo ʻia he kahiko ʻole a hilinaʻi ʻole.
He wahi koʻikoʻi kēia o ka hoʻonaʻauao no kēlā me kēia ma ka ʻoihana. ʻOiai ʻo PP (Polypropylene) he mea hou a hilinaʻi, PB (Polybutylene) kona pilikia ma mua. Mai ka makahiki 1970 a hiki i ka makahiki 1990, ua hoʻokomo nui ʻia ʻo PB no nā laina wai wela a me ke anuanu. Eia nō naʻe, ua ʻike ʻia ʻo nā kemika maʻamau i loko o ka wai kaona, e like me ka chlorine, ua hoʻouka i ka polybutylene a me kāna mau mea palaki, a ua palupalu lākou. Ua alakaʻi ʻia kēia i nā māwae hikiwawe a me nā leaks pōʻino, e hoʻoulu ai i nā piliona kālā i ka pōʻino wai ma nā hale lehulehu. Ke loaʻa ʻo Budi i kekahi manawa no nā pono PB, ʻo ia ka mea maʻamau no ka hoʻoponopono. Ua aʻo au iā ia e aʻo koke i ka mea kūʻai aku e pili ana i nā pilikia o ka ʻōnaehana PB holoʻokoʻa a paipai i kahi pani piha me kahi mea paʻa, mea hou e like mePP-R or PEX. ʻAʻole ia e pili ana i ke kūʻai nui ʻana; e pili ana i ka pale ʻana i ka mea kūʻai mai ka hāʻule ʻole e hiki mai ana.
Polypropylene (PP) vs. Polybutylene (PB)
| Hiʻona | PP (Polypropylene) | PB (Polybutylene) |
|---|---|---|
| Kūlana | ʻO kēia manawa, hilinaʻi, hoʻohana nui ʻia | ʻAi ʻole, ʻike ʻia no ka nui o ka hemahema |
| Palekana Kemika | Maikaʻi, kūpaʻa i ka wai i mālama ʻia | ʻAʻohe, hoʻohaʻahaʻa me ka ʻike ʻana i ka chlorine |
| ʻO ka hui ʻana | Hoʻohui wela hilinaʻi | Mechanical crimp fittings (pinepine i ka helu hemahema) |
| Manaʻo | Paipai ʻia no ka paipu hou a pani hou | Manaʻo ʻia e hoʻololi piha ʻia, ʻaʻole hoʻoponopono |
Ka hopena
ʻO nā pono PP, i hana ʻia mai ka polypropylene lōʻihi, ʻo ia ka mea e koho ai no ka wai wela a me nā ʻōnaehana kemika. ʻO lākou kahi hopena hou a hilinaʻi, ʻaʻole like me nā mea kahiko, hāʻule ʻole e like me polybutylene.
