Chiyambi cha PVC Capacity ku China ndi Padziko Lonse

Malinga ndi ziwerengero za mu 2020, mphamvu yopanga PVC padziko lonse lapansi idafika matani 62 miliyoni ndipo zotulutsa zonse zidafika matani 54 miliyoni.Kuchepetsa konse kwa zotulutsa kumatanthauza kuti mphamvu yopangira sinayendetse 100%.Chifukwa cha masoka achilengedwe, ndondomeko zam'deralo ndi zinthu zina, zotulukapo ziyenera kukhala zochepa kuposa mphamvu zopangira.Chifukwa cha kukwera mtengo kwa PVC ku Europe ndi Japan, mphamvu yopanga PVC yapadziko lonse lapansi imakhazikika kumpoto chakum'mawa kwa Asia, komwe China ili ndi theka la mphamvu zopanga PVC padziko lonse lapansi.

Malinga ndi mphepo deta, mu 2020, China, United States ndi Japan ndi zofunika PVC kupanga madera padziko lonse, ndi mphamvu kupanga mlandu 42%, 12% ndi 4% motero.Mu 2020, mabizinesi atatu apamwamba kwambiri padziko lonse lapansi opanga PVC pachaka anali Westlake, shintech ndi FPC.Mu 2020, mphamvu yopanga PVC pachaka inali matani 3.44 miliyoni, matani 3.24 miliyoni ndi matani 3.299 miliyoni motsatana.Kachiwiri, mabizinesi omwe amatha kupanga matani opitilira 2 miliyoni amaphatikizanso inovyn.Kuthekera kokwanira kwa China ndi matani ena 25 miliyoni, ndi matani 21 miliyoni mu 2020. Pali opanga oposa 70 a PVC ku China, 80% omwe ndi njira ya calcium carbide ndipo 20% ndi njira ya ethylene.

Njira zambiri za calcium carbide zimakhazikika m'malo olemera ndi malasha monga Inner Mongolia ndi Xinjiang.Malo opangira ma ethylene ali m'mphepete mwa nyanja chifukwa VCM kapena ethylene yaiwisi iyenera kutumizidwa kunja.China mphamvu kupanga nkhani pafupifupi theka la dziko, ndi kukula mosalekeza kwa unyolo China kumtunda mafakitale, ndi PVC mphamvu yopanga ethylene njira adzapitiriza kuwonjezeka, ndipo China adzapitiriza kuwononga mayiko PVC gawo.
