PVC SG-5 no ka paipu
PVC SG-5 no ka paipu,
PVC no ka hana paipu, PVC SG-5 resin,
Pono e koho ʻia ka resin Sg-5 me ka pae haʻahaʻa o ka polymerization i ka hana ʻana o ka paipu paʻakikī.ʻO ke kūlana kiʻekiʻe o ka polymerization, nā waiwai kino a me nā mechanical a me ka pale wela
ʻOi aku ka maikaʻi o nā waiwai, akā ʻo ka maikaʻi ʻole o ka resin e lawe mai i kekahi mau pilikia i ka hana ʻana, no laila ʻo ka viscosity maʻamau (1).7 ~ 1. 8) x 10-3 pa
• He kūpono ka SG-5 resin o S.Hoʻohana maʻamau ka paipu paʻa i ke alakaʻi stabilizer, kona kūpaʻa wela maikaʻi, hoʻohana mau ʻia ʻekolu alakaʻi kumu, akā
Hoʻohana mau ʻia me nā kopa kepau a me ka barium me ka lubricity maikaʻi.He mea koʻikoʻi ke koho ʻana a me ka hoʻohana ʻana i nā lubricants no ka hana paipu paʻakikī.
Pono e noʻonoʻo ʻia ka lubrication kūloko a me ka lubrication waho e hōʻemi i ka ikaika intermolecular, i hiki ke hoʻemi ʻia ka viscosity heheʻe no ka hana ʻana, a e pale aku i ka heheʻe.
E hoʻopili i ka metala wela e hāʻawi i kahi ʻālohilohi.Hoʻohana mau ʻia ka kopa metala no ka lubrication kūloko, a hoʻohana ʻia ka wax me ka helu heheʻe haʻahaʻa no ka lubrication waho.Kahu hoʻopiha
No ka hoʻohana ʻana i ka calcium carbonate a me ka barium (ka pauka barite), hana maikaʻi ka calcium carbonate i ka hana ʻana o ka paipu, hiki i ka barium ke hoʻomaikaʻi i ka hoʻoheheʻe ʻana, i maʻalahi ke ʻano o ka paipu, ʻelua.
Hiki ke ho'emi 'ia ke kumukū'ai, akā nui ka hopena i ka hana o ka paipu, 'oi aku ka maika'i o ka paipu pa'i a me ka paipu pale corrosion 'a'ole e ho'ohui a ho'ohui i ka mea ho'opiha li'ili'i.
He aha nā paipu PVC a me CPVC?
Paipu PVC
Hoʻokumu ʻia i nā makahiki 1930, ua lilo nā paipu PVC (polyvinyl chloride) i mea maʻamau no nā paipu kūloko a me nā ʻoihana a puni ka honua.Ma US, ʻekolu hapahā o nā hale a pau e hoʻohana i ka PVC.Mai ka 1950s, ua lilo ia i mea pani maʻamau no nā paipu metala
Hana ʻia ka PVC me ka hoʻohana ʻana i hoʻokahi o nā kaʻina polymerization ʻekolu: polymerization suspension, polymerization emulsion, a i ʻole polymerization bulk.Hana ʻia ka hapa nui o ka PVC me ka hoʻohana ʻana i ka polymerization suspension.
He mea nui e hoʻomaopopo i ka hele ʻana o nā paipu PVC i ʻelua ʻano: ʻoʻoleʻa a me ka ʻole.ʻO ke ʻano ʻoʻoleʻa paha ka mea mua i hiki i ka noʻonoʻo-e noʻonoʻo i ka wai inu, ka paipu, ka ʻōpala, a me ka mahiʻai.Hiki ke maʻalahi ke ʻano unplasticized, maikaʻi ia no ka hoʻohana ʻana i nā noi e like me ka paipu lapaʻau a me ka insulation no nā uea uila.
ʻO kekahi mau mea maikaʻi o ka paipu PVC me kona ikaika, ka lōʻihi kiʻekiʻe, ke kumu kūʻai haʻahaʻa, ka maʻalahi o ka hoʻokomo ʻana, a me ke kūpaʻa ʻana i ka ʻōpala a me ka corrosion.
Paipu CPVC
ʻO CPVC ka PVC i hoʻopili ʻia.ʻO ke kaʻina hana chlorination e hiki ai iā CPVC ke kū i nā mahana kiʻekiʻe a hiki i 200 ° F-a hoʻomaikaʻi i kona pale ahi a me ka corrosion.Ma muli o kona pale wela kiʻekiʻe, makemake ka hapa nui o nā code hale i nā paipu CPVC no nā noi wai wela, ʻoiai hiki ke hoʻohana ʻia no ka wai wela a me ke anuanu.Hoʻohui ʻia, hoʻohui nui ʻia ka CPVC i ka hoʻohana ʻana i nā ʻōnaehana sprinkler ahi.
Hoʻohui ka papa inoa o nā pono CPVC.ʻO ka mea hoʻokahi, ʻo kona kūpaʻa kemika a me ka wela e paʻa loa ia a hōʻoia i ka lōʻihi o ke ola.
Ma muli o kona hiki ke kū'ē i ka wela kiʻekiʻe a me kona ākea o nāʻoihana kālepa a me nāʻoihanaʻoihana, hiki mai ka CPVC ma kahi kumu kūʻai kiʻekiʻe ma mua o PVC.
He aha nā ʻokoʻa ma waena o nā paipu PVC a me CPVC?
ʻO ka ʻokoʻa nui ma waena o PVC a me CPVC ʻo ko lākou hiki ke pale i ka mahana.E like me ka mea i ʻōlelo ʻia ma mua, hiki i ka paipu CPVC ke kū a hiki i 200 ° F, akā hiki i ka paipu PVC ke ʻae a hiki i 140 ° F.Inā ʻoe e piʻi ma luna o kēlā mau wela, e hoʻomaka ana nā mea ʻelua e palupalu, hiki ke hoʻonāwaliwali nā ami a pau nā paipu.ʻO ka hopena, nui nā mea paipu e ʻōlelo aku e hoʻohana ʻoe i ka CPVC no nā laina wai wela a me ka PVC no nā laina wai anuanu.
ʻOiai he nui nā pōmaikaʻi o PVC, ʻoi aku ka maʻalahi o ka CPVC, a loaʻa i ka nui o ka paipu nominal (NPS) a me ka nui o ka pahu keleawe (CTS).ʻO ka hoʻohālikelike, loaʻa wale ka PVC i ka ʻōnaehana NPS.Loaʻa nā paipu ʻelua ma 10 ft a me 20 ft ka lōʻihi.
Ma ke ʻano o ka hiʻohiʻona, he keʻokeʻo a ʻeleʻele paha nā paipu PVC, a ʻo nā paipu CPVC he keʻokeʻo keʻokeʻo, hina hina, a melemele paha.Inā loaʻa kekahi nīnau, e paʻi ʻia nā kikoʻī ʻenehana ma ka ʻaoʻao.No ka mea, ʻokoʻa ka hui kemika ma waena o nā mea ʻelua, ʻaʻole pono e hoʻohana ʻia nā mea hoʻoheheʻe a me nā mea hoʻopaʻa.
He aha nā mea like ma waena o nā paipu PVC a me CPVC?
I ka pili ʻana i nā ʻenehana a me nā ʻano like kino, ʻo PVC a me CPVC ka papa inoa o nā pono.ʻO ka mea hoʻokahi, ʻo nā waiwai o nā paipu ʻelua e ʻae iā lākou e pale i ka corrosion a me ka hoʻohaʻahaʻa ʻana mai nā kemika.ʻO ka lua, palekana nā mea ʻelua e hoʻohana me ka wai inu ke hōʻoia ʻia ʻo ANSI / NSF 61.Hele mai lāua ʻelua ma ka Hōʻike 40 a me ka Hōʻike 80 mānoanoa, a loaʻa i ka hopena a me ka hopena bele.Hoʻohui ʻia, hele mai ka Hōʻike 40 PVS i nā lako papa 125.
Ma ke ʻano he bonus i hoʻohui ʻia i kā lākou kaʻina hoʻonohonoho maʻalahi, ʻoi loa ka hopena a me ka lōʻihi, e ʻae ana i ke ola o kanalima a kanahiku mau makahiki.A ʻaʻole like me ke keleawe, ʻaʻole hilinaʻi ke kumukūʻai o nā paipu PVC a me CPVC i ka waiwai kūʻai.
Hiki ke hana ʻia ka resin PVC i nā huahana plastik like ʻole.Hiki ke hoʻokaʻawale ʻia i nā huahana palupalu a paʻakikī e like me kāna noi.Hoʻohana nui ia no ka hana ʻana i nā pepa ʻālohilohi, nā paipu paipu, nā kāleka gula, nā mea hoʻokahe koko, nā paipu palupalu a paʻakikī, nā papa, nā puka a me nā puka makani.Nā kiʻi, nā kiʻiʻoniʻoni, nā mea hoʻoheheʻe uila, nā ʻaʻahu kaula, nā hoʻololi koko, etc.
Hoʻokumu ʻia ka koi PVC e nā huahana Construction, Agriculture, Packaging and Consumer Sectors.I ka mākeke kūloko, hoʻohana ʻia ka resin PVC e hana i nā huahana paʻa a palupalu PVC.Ma kahi o 55% o ka māhele mākeke e paʻa ʻia e ka PVC Pipes & Fittings segment wale nō, ʻo nā ʻāpana ʻē aʻe e pili ana i ka Film & Sheet, Cable Compound, Flexible hose, Shoes, Profile, Flooring and Foam Board.I ka mākeke kūloko o PVC, hoʻohana nui ʻia ka resin e hana i nā paipu PVC.Ma kahi o 55% o ka hoʻohana resin ma kēia ʻāpana wale nō.ʻO nā ʻāpana ʻē aʻe e pili ana i ka ʻili hana, nā kāmaʻa, nā lau ʻoi a me ka palupalu, nā kīhāpai kīhāpai, nā puka makani a me nā puka a me nā mea ʻē aʻe.
