Ine, kuwunika kwa msika
PVC(6402, 10.00, 0.16%) mgwirizano waukulu mu December 30 unatsekedwa pa 6263 yuan/tani, mwezi umodzi kukwera 312 yuan/tani (5.24%).
Kuyang'ana mmbuyo pa December lonse, mu theka loyamba la mweziwo, makontrakitala akuluakulu adawonetsa kukwera kwapamwamba chifukwa cha kuchotsedwa kwa ndondomeko ya mliri ndi kumasulidwa kwa ndondomeko ya nyumba.Mu theka lachiwiri la mweziwo, ndi kukhudzidwanso kwa mliriwu komanso kufunikira kwaulesi kumapeto kwa chaka, kuchuluka kwa zoperekera ndi zofunikila sikunapereke mayankho abwino, ndipo msika pang'onopang'ono udalowa pakuphatikizana kodabwitsa.Chakumapeto kwa chaka, zotsatira za tchuthi zinawonekeranso, kusonyeza kukwera kwakukulu.
II, kusanthula malo
PVC kupanga ndondomeko ali mitundu iwiri: kashiamu carbide njira ndi ethylene njira, ethylene njira ya PVC khalidwe koyera ndi yunifolomu, mtengo ndi apamwamba pang'ono kuposa kashiamu carbide PVC njira.Mitundu yobweretsera yamtsogolo ya PVC m'dziko lathu ndi SG5 grade 1 ikugwirizana ndi dziko lonse lapansi.Palibe zoletsa zomveka bwino ngati choperekacho chimapangidwa ndi njira ya calcium carbide kapena njira ya vinyl.
Pofika pa Disembala 30, 2022, mtengo wamalo ndi kufalikira kwa PVC zikuwonetsedwa pansipa:
Patsiku limenelo, mtengo wapakati wa vinyl PVC ku China unali 6,313 yuan/tani, kukwera 165 yuan/tani poyerekeza ndi kumapeto kwa mwezi watha.
Pa tsiku lomwelo, mtengo wapakati wa PVC wa calcium carbide wapakhomo ndi 6,138 yuan/ton, poyerekeza ndi kumapeto kwa mwezi watha, wakwera 198 yuan/ton.
Kusiyana kwamtengo pakati pa njira ya ethylene ndi njira ya calcium carbide patsikulo kunali 175 yuan/tani, poyerekeza ndi kumapeto kwa mwezi watha, kufika pa yuan 33/tani, kusiyana kwamitengo kukadali pamlingo wotsika kwambiri.
Pofika pa Disembala 30, 2022, kufalikira kwamitengo yamtsogolo ya PVC ndi -66 yuan/tani, 3 yuan/tani kutsika kuposa tsiku lapitalo, lomwe ndi lotsika kwambiri m'mbiri.
III.Kusanthula kwazinthu
Kwa nthawi yaitali, Chinese PVC msika wakhala chitsanzo chitukuko coexisting ndi mitundu iwiri ya mizere luso, njira kashiamu carbide ndi njira ethylene, koma chifukwa cha makhalidwe a "malasha olemera, mafuta osauka ndi mpweya wochepa" chuma m'dziko lathu, calcium carbide njira PVC yakhala ukadaulo wotsogola m'dziko lathu, koma pamsika wapadziko lonse lapansi, zinthu zazikuluzikulu za PVC zimapangidwa ndi njira ya ethylene, ndipo ethylene imapangidwa ndi kusweka kwamphamvu monga mafuta ndi gasi.Chifukwa chake mtengo wa PVC ndi mitengo yamafuta yapadziko lonse lapansi ikuwonetsa kulumikizana kolimba.
Njira yopangira vinyl PVC ili motere: mafuta akuda - naphtha - ethylene - dichloroethane (EDC) - vinyl chloride (VCM) - polyvinyl chloride (PVC)
Njira ya calcium carbide imagwiritsidwa ntchito kwambiri m'mabizinesi aku China opanga klori-alkali kupanga PVC, ndipo kutulutsa kwa PVC ndi njira ya calcium carbide kumatenga pafupifupi 80% yazinthu zonse ku China.
Kapangidwe ka calcium carbide polyvinyl chloride ndi: Malasha - calcium carbide - acetylene - vinyl chloride (VCM) - polyvinyl chloride (PVC) njira yochepetsera magetsi ndiyo njira yodziwika bwino yopangira calcium carbide pakali pano, njira iyi imatenga coke (2798). , 29,50, 1.07%) ndi laimu monga zopangira, malinga ndi chiŵerengero chokhazikika cha osakaniza mu ng'anjo yotsekedwa ya calcium carbide, Calcium carbide imapangidwa ndi kutentha kwa magetsi kwa madigiri 2000-2200.Popeza njira iyi ikufunika kuwononga mphamvu yamagetsi yochuluka, mtengo wamagetsi umakhala wokwera mtengo wamakampani opanga polyvinyl chloride pogwiritsa ntchito njira ya calcium carbide.
Kufotokozera mwachidule, mtengo wamtsogolo wa PVC umakhudzidwa ndi malasha otentha (0, -921.00, -100.00%) (mtengo wamagetsi), mitengo ya coke ndi calcium carbide panthawi imodzimodziyo, kusonyeza kugwirizana kwakukulu.
Pofika pa Januware 03, 2023, mtengo wam'tsogolo wa malasha aku China ndi 921 yuan/tani, poyerekeza ndi tsiku lapitalo, palibe kusintha;Mtengo wobweretsera coke ndi 2,610 yuan/tani, poyerekeza ndi tsiku lapitalo, kutsika 95 yuan/tani.
Pofika pa Disembala 30, 2022, mtengo wapakati wa calcium carbide m'mafakitole odziwika bwino a calcium carbide ku Northwest China ndi 3,910 yuan/ton, zomwe sizinasinthe poyerekeza ndi tsiku lapitalo.Mtengo wa calcium carbide mdziko muno ndi 4,101 yuan/ton, poyerekeza ndi tsiku lapitalo, palibe kusintha.
Mabizinesi a chlor-alkali akatulutsa chlorine yamadzimadzi, amapezanso koloko, chinthu chogwirizana nacho.M'zaka zaposachedwapa, mtengo wa caustic koloko ndi madzi klorini kupanga seesaw zotsatira, ndiko kuti, pamene mtengo wa caustic koloko ndi mkulu, mtengo wa madzi klorini ndi otsika, ndi mosemphanitsa, amene amapanga phindu la chlor-alkali. mabizinesi amakhalabe pamlingo woyenera.Madzi a klorini ndi ovuta kusunga ndi kunyamulidwa mtunda wautali, kotero opanga amakonda kupanga PVC ndikugwiritsa ntchito madzi ochulukirapo a klorini.
Mtsinje wa caustic soda makamaka umaphatikizapo alumina, kupanga mapepala, kusindikiza ndi utoto ndi mafakitale a mankhwala.Kutentha kwa mtsinje wa caustic koloko kudzayendetsa kuwonjezeka kwa mabizinesi a chlor-alkali, ndipo mankhwala amadzimadzi amadzimadzi amtundu wa PVC adzapangidwa kukhala PVC, motero akuwonjezera kuchuluka kwa msika wa PVC, komwe kukakamiza mtengo wamsika. PVC kumlingo wina.Kawirikawiri, mitengo ya PVC imakhalabe yokwera pamene mitengo ya caustic soda ili yotsika.
Pofika pa Disembala 30, 2022, mtengo wa ionic membrane caustic soda ndi 1,344 yuan/ton, poyerekeza ndi tsiku lapitalo, palibe kusintha, ndipo mtengo wapano uli pamalo apamwamba kwambiri akale.
Pakalipano, chofunika kwambiri cha soda caustic ku China chimachokera ku ulalo wopangira alumina, kotero mtengo wa caustic soda ndi mtengo wa alumina umasonyeza kugwirizanitsa kwakukulu.
Domestic electrolytic aluminium imagwiritsidwa ntchito kwambiri m'mafakitale ogulitsa nyumba, magalimoto ndi magetsi.Kubwezeretsanso kwa mafakitale akumunsiwa kudzakulitsa kufunika kwa zinthu za aluminiyamu, zomwe zidzatumizidwa kumtunda, kukankhira mtengo wa caustic soda ndikukhudza mwachindunji mtengo wamtsogolo wa PVC.
Pofika pa Disembala 30, 2022, mtengo wa alumina wam'nyumba ndi 2,965 yuan/tani, palibe kusintha poyerekeza ndi tsiku lapitalo, ndipo mtengo wapano uli pamalo apakatikati.
