ʻO ka nānāʻana i nā kumukūʻai hana PVC
ʻO ka nānā ʻana i nā kumukūʻai hana PVC,
kaʻina calcium carbide PVC, kumu kūʻai ethylene PVC, ʻO ke kumukūʻai PVC, Nā mea hana PVC, Vinyl kaʻina PVC kumu kūʻai,
I nā makahiki i hala iho nei, ua loli nui ke kumukūʻai o PVC, a ʻokoʻa loa ka loaʻa kālā o nā ʻoihana me nā kaʻina like ʻole.Loaʻa nā ʻoihana me ke kākoʻo ʻana i nā mea waiwai, aʻo nā ʻoihana e pono e hōʻiliʻili i nā kumu waiwai ke kū nei i nā poho.
E like me ke kaʻina hana o PVC e hoopau ana i 1.4 tons o ka calcium carbide no ton, ka loli oʻO ke kumukūʻai PVCʻO ke ʻano o ka calcium carbide e pili nui ʻia e ka calcium carbide.Mai ʻOkakopa 2020, ʻo ka piʻi ʻana o ke kumukūʻai o ka calcium carbide i alakaʻi i ka piʻi ʻana oʻO ke kumukūʻai PVC.Ma hope o 2021, ma lalo o ke kumu o ka loiloi o ka hoʻohana ʻana i ka uila, ka carbide calcium, ma ke ʻano he ʻoihana hoʻohana kiʻekiʻe, ua kaupalena ʻia.Ke piʻi nei ke kumukūʻai o nā ʻoihana PVC me ka piʻi.I ʻOkakopa 2021, ʻoi aku ke kumukūʻai o kekahi mau ʻoihana ma Kina Hikina ma mua o 15000 yuan/ton.Ma ka hopena o 2022, ua mālama ʻia ke kumukūʻai calcium carbide ma 3900-4550 yuan / ton, me ke kumukūʻai kiʻekiʻe e ʻike ʻia i ka waena o Malaki a me ke kumu kūʻai haʻahaʻa i ka hopena o Pepeluali a me ʻApelila.No laila, like pū ke kumukūʻai o nā ʻoihana PVC.
Vinyl kaʻina PVC kumu kūʻaiHoʻololi ʻia nā loli e ke kumukūʻai o ka ethylene a me ka vinyl chloride.Ke piʻi mālie nei ke kumukūʻai o nā ʻoihana PVC e hoʻohana ana i ke ʻano ethylene mai ka hopena o ʻApelila 2020, e hoʻomaka ana mai ka hoʻololi ʻana o VCM, ʻike ʻia ke kūlana kiʻekiʻe i ka hopena o ʻOkakopa 2021, ʻoi aku ma mua o 14,600 yuan/ton.I Ianuali 2022, ua hoʻonui ʻia ka hāʻawi ʻana i ka vinyl chloride, a ua emi ke kumukūʻai o nā ʻoihana hana PVC i ka hana ethylene;I Feberuari vinyl chloride downstream noi i hoʻomaikaʻi, ua piʻi ke kumukūʻai;I Malaki, ua paʻa ka lako o ka VCM ma Asia, a ʻo ke kumu kūʻai kiʻekiʻe loa he 9750 yuan/ton i ka hopena o Malaki.
I ka hapaha mua o 2022, ua kūpono ke kiʻekiʻe o ka calcium carbide PVC, ʻoi aku ka maikaʻi o ke kumukūʻai haʻahaʻa o ka calcium carbide raw.I Ianuali, ʻo ka waiwai nui o PVC i hana ʻia e ka ʻeli ʻana o nā ʻāina ʻē ma Shandong he 33.6 yuan/ton, he piʻi o 1182.6 yuan/ton, a he piʻi o 6.6 yuan/ton i kēlā me kēia makahiki;I ka hopena o Feberuari, ua hoʻonui ʻia ka loaʻa kālā o PVC i hana ʻia ma waho o ka hana electrolytes e 165.5 yuan/ton i 199.1 yuan/ton.I ka hopena o Malaki, ʻo 774 yuan/ton ka loaʻa kālā o PVC i hana ʻia e nā pōhaku electrolytic.
Wahi a ka moʻohelu kālā mai VCM, i ka hapaha mua o 2022, ʻoi aku ka haʻahaʻa o ka pae waiwai o PVC i hana ʻia e ke ʻano ethylene ma mua o nā ʻoihana calcium carbide method.I Ianuali, ke kumukūʻai oNā mea hana PVCi lalo, ua piʻi iki ke kumukūʻai ma ka mākeke, a ua hoʻonui ka waiwai o nā ʻoihana.I loko o Feberuari, pili i ke kumu kūʻai kiʻekiʻe o ka maka vinyl chloride, ethylene ala mahuahua kumu kūʻai, i ka manawa like i ka waena a me ka hopena o Feberuari hoʻomaka e hoʻonāwaliwali i ka market au, ethylene kumu kuai loosening, vinyl ala o waho hana o oi poho.I Malaki, i ka piʻi ʻana o ke kumukūʻai o PVC a hāʻule ke kumu kūʻai o VCM, ua hoʻomaikaʻi ka waiwai o nā ʻoihana PVC e hoʻohana ana i ka ethylene method (PVC).Akā ʻo nā ʻoihana vinyl PVC i loko o nā ʻoihana i hoʻohui ʻia, a ʻoi aku ka nui o ka loaʻa kālā ma mua o nā ʻoihana PVC.
ʻO PVC kahi acronym no ka polyvinyl chloride.ʻO ka resin kahi mea i hoʻohana pinepine ʻia i ka hana ʻana i nā plastics a me nā rubbers.ʻO ka resin PVC kahi pauka keʻokeʻo i hoʻohana mau ʻia e hana i nā thermoplastics.He mea synthetic ia i hoʻohana nui ʻia i ka honua i kēia lā.ʻO ka polyvinyl chloride resin he mau hiʻohiʻona koʻikoʻi e like me ka nui o nā mea maka, ka ʻenehana hana makua, ke kumu kūʻai haʻahaʻa, a me ka nui o nā hoʻohana.He mea maʻalahi ka hana a hiki ke hana ʻia e ka hoʻoheheʻe ʻana, laminating, injection molding, extrusion, calendering, blow molding a me nā ʻano hana ʻē aʻe.Me nā waiwai kino a me nā kemika maikaʻi, hoʻohana nui ʻia ia i ka ʻoihana, ke kūkulu ʻana, ka mahiʻai, ke ola o kēlā me kēia lā, ka pahu, ka uila, nā pono lehulehu, a me nā ʻano ʻē aʻe.ʻO nā resins PVC maʻamau he kūʻē kemika kiʻekiʻe.He ikaika loa a kū i ka wai a me ka abrasion.Hiki ke hana ʻia ka polyvinyl chloride resin (PVC) i nā huahana plastik like ʻole.ʻO ka PVC he mea maʻalahi, kūʻaiʻole, a pili i ke kaiapuni.Hiki ke hoʻohana ʻia ʻo Pvc Resin i nā paipu, nā puka makani, nā ʻili, nā ʻili, nā uea, nā kāmaʻa a me nā huahana palupalu maʻamau ʻē aʻe, profiles, fittings, panels, injection, moulding, kāmaʻa, paipu paʻa a me nā mea hoʻonaninani, nā ʻōmole, nā pepa, kalena, ʻo ka hoʻoheheʻe ʻana a me nā mea hoʻoheheʻe, a me nā mea ʻē aʻe.
Nā hiʻohiʻona
ʻO PVC kekahi o nā resins thermoplastic i hoʻohana nui ʻia.Hiki ke hoʻohana ʻia e hana i nā huahana me ka paʻakikī kiʻekiʻe a me ka ikaika, e like me nā paipu a me nā mea pono, nā puka profiled, nā puka makani a me nā pepa paʻi.Hiki iā ia ke hana i nā huahana palupalu, e like me nā kiʻiʻoniʻoni, nā pepa, nā uwea uila a me nā kaula, nā papa papahele a me nā ʻili synthetic, me ka hoʻohui ʻana i nā plasticizers.
