Ke ho'āʻo nei ʻoe e kauoha i nā kiwi, akā kapa ʻia kekahi mea kūʻai iā PVC a kapa ʻia kekahi iā UPVC. Ke hopohopo nei kēia huikau iā ʻoe ke hoʻohālikelike nei i nā huahana like ʻole a kūʻai ʻole paha i ka mea hewa.
No nā kiwi pōpō paʻa, ʻaʻohe ʻokoʻa ma waena o PVC a me UPVC. Pili nā huaʻōlelo ʻelua i ka mea likemea polyvinyl chloride unplasticized, ka mea ikaika, pale ʻino, a kūpono no nā ʻōnaehana wai.
ʻO kēia kekahi o nā nīnau maʻamau i loaʻa iaʻu, a ke hana nei ia i ka huikau pono ʻole i ke kaulahao lako. Ua kamaʻilio wau me Budi, he luna kūʻai mai kahi mea hoʻolaha nui ma Indonesia. Ke hoʻopaʻa nei kāna mau mea kūʻai liʻiliʻi hou, me ka manaʻo e pono lākou e hoʻopuka i ʻelua ʻano ʻano valve. Ua wehewehe au iā ia no nā kiwi ʻoʻoleʻa a mākou e hana nei ma Pntek, a no ka hapa nui o ka ʻoihana, hoʻohana ʻia nā inoa. ʻO ka hoʻomaopopo ʻana i ke kumu e hāʻawi ai ʻoe i ka hilinaʻi i kāu mau hoʻoholo kūʻai.
Aia kekahi ʻokoʻa ma waena o PVC a me UPVC?
ʻIke ʻoe i ʻelua acronyms ʻokoʻa a manaʻo maoli ʻoe he 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.
ʻO ka mea nui, ʻaʻole. I loko o ka pōʻaiapili o nā paipu paʻakikī a me nā valve, ua like ka PVC a me ka UPVC. ʻO ka "U" ma UPVC ke kū nei no "unplasticized," he ʻoiaʻiʻo ia no nā kiwi PVC paʻa a pau.
Mai ka moʻolelo o nā plastics ka huikau. ʻO Polyvinyl chloride (PVC) ka mea kumu. No ka hoʻololi ʻana i nā huahana e like me nā hose kīhāpai a i ʻole ka uila uila, hoʻohui nā mea hana i nā mea i kapa ʻia he plasticizers. No ka hoʻokaʻawale ʻana i ke ʻano kumu, ʻoʻoleʻa 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 kaomi, ʻaʻole ʻoe e hoʻohana i ka mana maʻalahi. ʻO nā paipu PVC koʻikoʻi a pau, nā mea pono, a me nā kiwi pōpō, ma ko lākou ʻano, ʻaʻole i hoʻopili ʻia. No laila, ʻoiai ke kapa inoa nei kekahi mau hui i kā lākou huahana "UPVC" i ʻoi aku ka kikoʻī, a ʻo nā mea ʻē aʻe ke hoʻohana wale nei i ka "PVC" maʻamau, ke kuhikuhi nei lākou i ka mea ikaika like ʻole. Ma Pntek, kāhea mākou iā lākouʻO nā kiwi pōpō PVCno ka mea, ʻo ia ka huaʻōlelo maʻamau, akā he UPVC maʻamau.
He mea maikaʻi paha nā kiwi pōpō PVC?
ʻIke ʻoe he plastik ka PVC a ʻoi aku ke kumukūʻai ma mua o ka metala. ʻO kēia ka mea e nīnau ai iā ʻoe i kona maikaʻi a noʻonoʻo inā paʻa ia no kāu mau noi koʻikoʻi a lōʻihi.
ʻAe, ʻoi aku ka maikaʻi o nā kiwi pōpō PVC kiʻekiʻe no kā lākou kumu i manaʻo ʻia. ʻAʻole lākou i ka ʻōpala a me ka corrosion, māmā, a hāʻawi i kahi ola lawelawe lōʻihi i nā noi wai anuanu, ʻoi aku ka nui o nā kiwi metala.
ʻAʻole ko lākou waiwai i ko lākou kumu kūʻai haʻahaʻa; aia ia i kā lākou hana ma nā wahi kikoʻī. ʻO nā pahu metala, e like me ke keleawe a i ʻole ka hao, e ʻele a ʻino paha i ka wā lōʻihi, ʻoi aku hoʻi i nā ʻōnaehana me ka wai i mālama ʻia, ka wai paʻakai, a i ʻole kekahi mau kemika. Hiki i kēia ʻino ke hoʻopaʻa i ka valve, ʻaʻole hiki ke huli i kahi pilikia. ʻAʻole hiki i ka PVC ke pala. ʻAʻole inert kemika i ka nui o nā mea hoʻohui wai, nā paʻakai, a me nā ʻakika māmā. ʻO ia ke kumu e hoʻohana wale ai nā mea kūʻai aku a Budi i ka ʻoihana kai iʻa kai ma Indonesia i nā valve PVC. E hoʻopau ka wai paʻakai i nā kiwi metala i loko o ʻelua mau makahiki, akā ke hoʻomau nei kā mākou mau kiwi PVC i ka holo mālie no nā makahiki he ʻumi a ʻoi aku paha. No kekahi noi ma lalo o 60°C (140°F), aPuka kinipopo PVCʻaʻole ia he koho "ʻoi aku ka maikaʻi"; ʻo ia ka mea ʻoi aku ka hilinaʻi a ʻoi aku ka lōʻihi o ka koho no ka mea ʻaʻole ia e hopu i ka corrosion.
He aha ke ʻano maikaʻi o ka pōlele pōlele?
Makemakeʻoe e kūʻai i ka valve "maikaʻi" e hōʻoia i ka hilinaʻi o kāu pūnaewele. Akā me ka nui o nā mea i loaʻa, ʻo ke koho ʻana i ka mea maikaʻi loa e manaʻo nui a paʻakikī.
ʻAʻohe pahu pōlele "maikaʻi" hoʻokahi no kēlā me kēia hana. ʻO ka valve maikaʻi loa ka mea nona nā mea a me ka hoʻolālā i hoʻohālikelike pono ʻia i ka mahana o kāu ʻōnaehana, kaomi, a me ka ʻenekini kemika.
ʻO ka "Best" pili mau i ka noi. ʻO ke koho hewa ʻana ua like ia me ka hoʻohana ʻana i kahi kaʻa haʻuki e huki ʻiliʻili—ʻo ia ka mea hana hewa no ka hana. He mea maikaʻi ke kiwi kila kuhili no nā wela kiʻekiʻe a me nā puʻe, akā he mea kūʻai nui no ka ʻōnaehana holo wai, kahi i ʻoi aku ka maikaʻi o ka valve PVC ma muli o kāna.pale ʻana i ka chlorine. Ke alakaʻi mau nei au i kaʻu mau hoa e noʻonoʻo e pili ana i nā kūlana kūikawā o kā lākou papahana. ʻO ka valve PVC ka mea lanakila no nā ʻōnaehana wai anuanu ma muli o kona kūpaʻa ʻana a me ke kumukūʻai. No ka wai wela, pono ʻoe e piʻi i lunaCPVC. No ke kinoea kiʻekiʻe a i ʻole ka aila, he koho kuʻuna a hilinaʻi ke keleawe. No ka hoʻohana ʻana i ka meaʻai a i ʻole nā kemika corrosive loa, koi pinepine ʻia ke kila kuhili. ʻO ka koho "maikaʻi" maoli ka mea e hāʻawi ai i ka palekana i koi ʻia a me ka lōʻihi no ka uku haʻahaʻa haʻahaʻa.

He aha ka ʻokoʻa ma waena o PVC U a me UPVC?
I ka manawa wale nō i manaʻo ai ʻoe ua maopopo iā PVC vs. UPVC, ʻike ʻoe i ka "PVC-U" ma kahi palapala ʻenehana. Hoʻohui kēia huaʻōlelo hou i kahi ʻāpana o ka huikau, e noʻonoʻo ʻoe i kou ʻike.
ʻAʻohe ʻokoʻa iki. ʻO PVC-U kahi ala ʻē aʻe e kākau ai i ka uPVC. ʻO ka "-U" ke kū nei no ka unplasticized. He hui 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 "100 dollars" me "100 mau kālā." He mau hua'ōlelo likeʻole lākou no ka mea like. I ka honua o nā plastics, ua hoʻomohala nā ʻāpana like ʻole i nā ʻano like ʻole e hōʻailona 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 o ka honua, ʻo "PVC-U" ka huaʻōlelo ʻenehana maʻamau e wehewehe i ka "unplasticized." No ka mea kūʻai e like me Budi, he ʻāpana koʻikoʻi kēia o kāna hui. Ke ʻike lākou i kahi palupalu ʻEulopa e hōʻike ana i nā kīwaha PVC-U, ʻike lākou me ka hilinaʻi e hoʻokō pono kā mākou mau pahu PVC maʻamau i ke koi. Hele mai nā mea a pau i ka mea like: he polymer vinyl paʻa, ikaika, unplasticized i kūpono no nā kiwi pōpō. Mai komo i ka palapala; e nānā i nā waiwai a me nā kūlana hana.
Ka hopena
ʻO PVC, UPVC, a me PVC-U e pili ana i ka mea ʻoʻoleʻa like ʻole, pono ʻole no nā kiwi pōlele wai anuanu. ʻO nā ʻokoʻa inoa he mau kuʻina kūloko a i ʻole mōʻaukala.
