Ke hoʻāʻo nei ʻoe e kauoha i nā kiwikā, akā kapa kekahi mea hoʻolako iā lākou he PVC a kapa kekahi iā lākou he UPVC. Hopohopo kēia huikau iā ʻoe e hoʻohālikelike ana ʻoe i nā huahana like ʻole a kūʻai paha i ka mea hewa.

No nā kiwikā poepoe paʻa, ʻaʻohe ʻokoʻa kūpono ma waena o PVC a me UPVC. Pili nā huaʻōlelo ʻelua i ka mea likemea polyvinyl chloride i hoʻopili ʻole ʻia, he ikaika, kūpaʻa i ka pala, a kūpono hoʻi no nā ʻōnaehana wai.

ʻO kēia kekahi o nā nīnau maʻamau aʻu e loaʻa ai, a hoʻokumu ia i ka huikau pono ʻole i loko o ke kaulahao lako. Ua kamaʻilio wau me Budi i hala koke aku nei, he luna kūʻai mai kahi mea hoʻolaha nui ma Indonesia. Ua paʻa kāna mau mea kūʻai hou, me ka manaʻo e pono lākou e kiʻi i ʻelua ʻano valves like ʻole. Ua wehewehe au iā ia no nā valves paʻa a mākou e hana ai ma Pntek, a no ka hapa nui o ka ʻoihana, hoʻohana like ʻia nā inoa. ʻO ka hoʻomaopopo ʻana i ke kumu e hāʻawi iā ʻoe i ka hilinaʻi i kāu mau hoʻoholo kūʻai.

Aia kekahi ʻokoʻa ma waena o ka PVC a me ka UPVC?

ʻIke ʻoe i ʻelua mau pōkole like ʻole a manaʻo maoli lākou e hōʻike ana i ʻelua mau mea like ʻole. Hiki i kēia kānalua ke hoʻolohi i kāu mau papahana i kou hoʻāʻo ʻana e hōʻoia i nā kikoʻī pololei.

ʻAʻole maoli. Ma ke ʻano o nā paipu paʻakikī a me nā kiwikā, ua like ʻo PVC a me UPVC. ʻO ke ʻano o ka "U" ma UPVC no "unplasticized," ʻo ia hoʻi no nā kiwikā PVC paʻa a pau.

ʻO ka huikau mai ka mōʻaukala o nā plastics. ʻO Polyvinyl chloride (PVC) ke kumu. I mea e maʻalahi ai no nā huahana e like me nā hoses māla a i ʻole ka insulation uea uila, hoʻohui nā mea hana i nā mea i kapa ʻia ʻo plasticizers. No ka hoʻokaʻawale ʻana i ke ʻano kumu, paʻa mai ka mana maʻalahi, ua puka mai ka huaʻōlelo "unplasticized" a i ʻole "UPVC". Eia nō naʻe, no nā noi e like me nā ʻōnaehana wai pressurized, ʻaʻole ʻoe e hoʻohana i ka mana maʻalahi. ʻO nā paipu PVC paʻa a pau, nā mea hoʻopili, a me nā valves pōpō, ma ko lākou ʻano, ʻaʻole i plasticized. No laila, ʻoiai kekahi mau hui e kapa ana i kā lākou huahana "UPVC" e ʻoi aku ka kikoʻī, a ʻo kekahi e hoʻohana wale i ka "PVC" maʻamau, ke kuhikuhi nei lākou i ka mea ikaika like a paʻa. Ma Pntek, kapa wale mākou iā lākouNā kiwikā poepoe PVCno ka mea ʻo ia ka huaʻōlelo maʻamau loa, akā ua hana ʻia lākou a pau me UPVC.

He maikaʻi anei nā kiwikā poepoe PVC?

ʻIke ʻoe he palaki ka PVC a ʻoi aku ke kumukūʻai ma mua o ka metala. ʻO kēia ke kumu e nīnau ai ʻoe i kona ʻano a noʻonoʻo inā lawa kona paʻa no kāu mau noi koʻikoʻi a lōʻihi.

ʻAe, maikaʻi loa nā kiwikā poepoe PVC kiʻekiʻe no kā lākou kumu i manaʻo ʻia. Pale lākou i ka popo a me ka pala, māmā, a hāʻawi i kahi ola lawelawe lōʻihi i nā noi wai anuanu, e ʻoi aku ka maikaʻi ma mua o nā kiwikā metala.

ʻAʻole wale ko lākou waiwai i ko lākou kumukūʻai haʻahaʻa; aia i kā lākou hana ma nā wahi kikoʻī. ʻO nā kiwikā hao, e like me ke keleawe a i ʻole ka hao, e popo a pala paha i ka hala ʻana o ka manawa, ʻoiai i nā ʻōnaehana me ka wai i mālama ʻia, ka wai paʻakai, a i ʻole kekahi mau kemika. Hiki i kēia pala ke hoʻopaʻa i ka kiwikā, e hiki ʻole ai ke huli i kahi pilikia. ʻAʻole hiki i ka PVC ke popo. He inert kemika ia i ka hapa nui o nā mea hoʻohui wai, nā paʻakai, a me nā waikawa palupalu. ʻO ia ke kumu e hoʻohana wale ai nā mea kūʻai aku a Budi ma ka ʻoihana mahiʻai kai ma Indonesia i nā kiwikā PVC. E luku ka wai paʻakai i nā kiwikā metala i loko o kekahi mau makahiki wale nō, akā hoʻomau ka hana maikaʻi o kā mākou mau kiwikā PVC no hoʻokahi ʻumi makahiki a ʻoi aku paha. No kekahi noi ma lalo o 60°C (140°F), akiwikā poepoe PVCʻaʻole wale ia he koho "ʻoi aku ka makepono"; ʻo ia pinepine ke koho hilinaʻi a lōʻihi hoʻi no ka mea, ʻaʻole ia e pale ʻia e ka pala.

He aha ke ʻano o ka valve pōpō maikaʻi loa?

Makemake ʻoe e kūʻai i ka valve "maikaʻi loa" e hōʻoia i ka hilinaʻi o kāu ʻōnaehana. Akā me ka nui o nā mea i loaʻa, ʻo ke koho ʻana i ka mea maikaʻi loa he mea paʻakikī a pilikia hoʻi.

ʻAʻohe kiwikā pōpō "maikaʻi loa" hoʻokahi no kēlā me kēia hana. ʻO ka kiwikā maikaʻi loa ka mea nona nā mea a me ka hoʻolālā i kūpono loa i ka mahana, ke kaomi, a me ke kaiapuni kemika o kāu ʻōnaehana.

ʻO ka "ʻOi loa" e pili mau ana i ka noi. ʻO ke koho ʻana i ka mea hewa e like me ka hoʻohana ʻana i kahi kaʻa haʻuki e huki i ka ʻiliʻili—ʻo ia ka mea hana hewa no ka hana. He mea maikaʻi loa ka valve kila kila no nā mahana kiʻekiʻe a me nā kaomi, akā he pipiʻi nui ia no kahi ʻōnaehana hoʻolaha loko wai, kahi i ʻoi aku ka maikaʻi o ka valve PVC ma muli o kānake kū'ē ʻana i ka chlorineKe alakaʻi mau nei au i kaʻu mau hoa hana e noʻonoʻo e pili ana i nā kūlana kikoʻī o kā lākou papahana. ʻO ka valve PVC ke poʻokela no nā ʻōnaehana wai anuanu ma muli o kona kūpaʻa i ka pala a me ke kumukūʻai. No ka wai wela, pono ʻoe e piʻi i luna eCPVCNo ke kinoea a i ʻole ka ʻaila me ke kaomi kiʻekiʻe, he koho kuʻuna a hilinaʻi hoʻi ke keleawe. No nā noi papa meaʻai a i ʻole nā ​​​​kemika ʻino loa, pono pinepine ke kila kila. ʻO ke koho "maikaʻi loa" ʻo ia ka mea e hāʻawi i ka palekana a me ke ola lōʻihi e pono ai no ke kumukūʻai haʻahaʻa loa.

He aha ka ʻokoʻa ma waena o ka PVC U a me ka UPVC?

I kou manawa i manaʻo ai ua maopopo iā ʻoe ʻo PVC vs. UPVC, ʻike ʻoe iā "PVC-U" ma kahi palapala loea. Hoʻohui kēia huaʻōlelo hou i kahi papa o ka huikau, e hoʻolilo ana iā ʻoe e kānalua i kāu ʻike.

ʻAʻohe ʻokoʻa iki. ʻO PVC-U kekahi ʻano kākau ʻana i ka uPVC. ʻO ka "-U" hoʻi ke kū nei no ka unplasticized. He ʻano inoa ia i ʻike pinepine ʻia ma nā kūlana ʻEulopa a i ʻole ka honua (e like me DIN a i ʻole ISO).

E noʻonoʻo e like me ka ʻōlelo ʻana he "100 kālā" me "100 kālā." He mau huaʻōlelo like ʻole kēia no ka mea like. I loko o ke ao o nā plastics, ua hoʻomohala nā wahi like ʻole i nā ʻano like ʻole e lepili ai i kēia mea. Ma ʻAmelika ʻĀkau, ʻo "PVC" ka huaʻōlelo maʻamau no ka paipu paʻa, a hoʻohana ʻia ʻo "UPVC" i kekahi manawa no ka maopopo. Ma ʻEulopa a ma lalo o nā kūlana honua, ʻo "PVC-U" ka huaʻōlelo ʻenekinia maʻamau e kuhikuhi i ka "unplasticized." No kahi mea kūʻai e like me Budi, he ʻāpana ʻike koʻikoʻi kēia no kāna hui. Ke ʻike lākou i kahi ʻelele ʻEulopa e kuhikuhi ana i nā valves PVC-U, ʻike lākou me ka hilinaʻi e hoʻokō pono ana kā mākou mau valves PVC maʻamau i ke koi. Hiki mai nā mea a pau i ka mea like: he polymer vinyl paʻa, ikaika, unplasticized i kūpono no nā valves pōpō. Mai hopu ʻia i nā leka; e kālele ana i nā waiwai o ka mea a me nā kūlana hana.

Hopena

ʻO PVC, UPVC, a me PVC-U nā mea a pau e pili ana i ka mea paʻa like, ʻaʻole i hoʻopili ʻia i kūpono no nā kiwikā pōpō wai anuanu. ʻO nā ʻokoʻa inoa he mau kuʻuna kūloko a mōʻaukala paha.
