Chiyambi cha Mphamvu ya PVC ku China ndi Padziko Lonse

Malinga ndi ziwerengero za mu 2020, mphamvu yonse yopanga PVC padziko lonse lapansi idafika matani 62 miliyoni ndipo mphamvu yonse yotulutsa idafika matani 54 miliyoni. Kuchepa konse kwa mphamvu yonse yotulutsa kumatanthauza kuti mphamvu yopangira sinayende bwino 100%. Chifukwa cha masoka achilengedwe, mfundo zakomweko ndi zina, mphamvu yotulutsa iyenera kukhala yocheperako poyerekeza ndi mphamvu yopangira. Chifukwa cha mtengo wokwera wa PVC ku Europe ndi Japan, mphamvu yonse yopangira PVC padziko lonse lapansi imapezeka makamaka kumpoto chakum'mawa kwa Asia, komwe China ili ndi theka la mphamvu yonse yopangira PVC padziko lonse lapansi.

Malinga ndi deta ya mphepo, mu 2020, China, United States ndi Japan ndi madera ofunikira kwambiri opanga PVC padziko lonse lapansi, ndipo mphamvu zopangira zinali 42%, 12% ndi 4% motsatana. Mu 2020, mabizinesi atatu apamwamba kwambiri padziko lonse lapansi omwe amapanga PVC pachaka anali Westlake, shintech ndi FPC. Mu 2020, mphamvu zopangira PVC pachaka zinali matani 3.44 miliyoni, matani 3.24 miliyoni ndi matani 3.299 miliyoni motsatana. Kachiwiri, mabizinesi omwe amapanga matani opitilira 2 miliyoni akuphatikizaponso inovyn. Mphamvu yonse yopanga ku China ndi matani ena 25 miliyoni, omwe amapanga matani 21 miliyoni mu 2020. Pali opanga PVC opitilira 70 ku China, 80% mwa iwo ndi njira ya calcium carbide ndipo 20% ndi njira ya ethylene.

Njira zambiri za calcium carbide zimapezeka m'malo okhala ndi malasha ambiri monga Inner Mongolia ndi Xinjiang. Malo opangira ethylene amapezeka m'mphepete mwa nyanja chifukwa VCM kapena ethylene imafunika kutumizidwa kunja. Mphamvu yopangira ku China ndi pafupifupi theka la dziko lapansi, ndipo chifukwa cha kukula kosalekeza kwa unyolo wa mafakitale aku China, mphamvu yopangira PVC ya njira ya ethylene ipitilira kuwonjezeka, ndipo China ipitiliza kuwononga gawo la PVC lapadziko lonse lapansi.
