Ukuhlaziywa kwentengo yaseChina PVC
Ukuhlaziywa kwamanani e-PVC yaseChina,
Intengo yaseChina ye-PVC FOB, I-Formosa pvc, Imakethe ye-PVC, Intengo ye-PVC,
Ngo-2022, ukuhlinzekwa komhlaba wonkeImakethe ye-PVCizokwanela;Kusukela ngo-2020, njengezwe elithumela ngaphandle elikhulu kunawo wonke emhlabeni - i-United States, ngaphansi kwethonya lezikhukhula namagagasi abandayo, ukulahleka kwayo kokukhiqizwa kwe-PVC kwasekhaya kwaba ku-40%.Ngekota yesine ka-2021, inani le-force majeure kanye nomthelela wedivayisi kususiwe, ukutholwa kwamandla okuhlinzeka.
Phakathi nenkathi ka-2020-2021, ngenxa yethuba elilethwe igebe le-EXPORT e-United States, inani elikhulu le-PVC e-China langenisa isikhala esihle se-arbitrage, futhi umthamo wokuthekelisa waqhubeka nokukhula.Ngo-2021, ifinyelele irekhodi eliphakeme lamathani angaphezu kwe-175.Ngo-2022, ngokutholwa kabusha kokuhlinzekwa komhlaba wonke, ingcindezi yokuthumela ngaphandle kwe-PVC e-China yanda.
Ngokombono wentengo yokuthekelisa yase-Taiwan, isifunda esikhulu sokuthekelisa e-Asia, intengo yokuthekelisa ye-PVC yase-Taiwan yaqala ukukhuphuka kusukela ngekota yesine ka-2020, futhi yaqhubeka nokufinyelela inani eliphakeme kakhulu emlandweni ngoNovemba 2021. Nokho, ngo-2022, nakuba amanani ehlala ephakeme, amanani enkathi yendabuko ephakeme kakhulu ayehla, kodwa akhuphuka ngo-April.Izintengo zamandla omhlaba ziphezulu, okuletha ukwesekwa okuqondile kakhulu emananini aphezulu ngoMashi no-Ephreli.
Emakethe yase-Asia, yendabukoIntengo ye-PVCikakhulukazi ibhekisela ekhotheshini yeFormosa Plastics, eChina.Nokho, ngomthelela wevolumu yokuthunyelwa kwe-PVC yaseChina eminyakeni emibili edlule, amandla entengo entengo yokuthekelisa yaseShayina nawo ayakhula.Ngokuvamile, ikhotheshini yanyanga zonke ye-Formosa Plastics yangaphambi kokudayiswa, ngaphezu kokunaka isidingo semakethe yaseNdiya, eminyakeni yamuva nje, intengo yokuthekelisa yezwe elikhulu njengereferensi ebalulekile, futhi njengomehluko wamanani, izikhathi eziningi iqinisekise ukulungiswa. isikhala sekhotheshini yeFormosa Plastics yaseChina;Ngokusekelwe kumamodeli edatha amaningi, sikholwa ukuthi kuleli sonto, ikhotheshini ethengiswa ngaphambili yase-China Taiwan Formosa Plastics June PVC kulindeleke ukuthi iqhubeke yehle ngo-$100-150/ton FOB uma kuqhathaniswa noMeyi.
I-S-1000 polyvinyl chloride resin ikhiqizwa inqubo ye-polymerization yokumiswa kusetshenziswa i-vinyl chloride monomer njengento eluhlaza.Iwuhlobo lwenhlanganisela ye-polymer enobuningi obuhlobene obungu-1.35 ~ 1.40.Iphuzu layo lokuncibilika licishe libe ngu-70 ~ 85℃.Ukungaqini kahle kokushisa nokumelana nokukhanya, ngaphezu kuka-100 ℃ noma isikhathi eside ngaphansi kwelanga i-hydrogen chloride iqala ukubola, ukukhiqizwa kwepulasitiki kudinga ukwengeza izinza.Umkhiqizo kufanele ugcinwe endaweni eyomile futhi engenawo umoya.Ngokwenani le-plasticizer, ukuthamba kwepulasitiki kungalungiswa, futhi i-resin yokunamathisela ingatholakala nge-emulsion polymerization.
IBanga S-1000 lingasetshenziswa ukukhiqiza ifilimu ethambile, ishidi, isikhumba esenziwe ngumuntu, amapayipi, ibha enomumo, ibhongo, amapayipi okuvikela ikhebula, ifilimu yokupakisha, isoli nezinye izimpahla ezithambile.
