Kachitidwe ka PVC, Kachitidwe ka Carbide PVC ndi Ethylene PVC

PVC ndi mtundu wa pulasitiki womwe umagwiritsidwa ntchito kwambiri popanga zipangizo zomangira. Chifukwa chake, sudzasinthidwa kwa nthawi yayitali mtsogolo, ndipo udzakhala ndi mwayi waukulu wogwiritsidwa ntchito m'madera omwe sanakule bwino mtsogolo.

Monga tonse tikudziwira, pali njira ziwiri zopangira PVC, imodzi ndi njira ya ethylene yodziwika padziko lonse lapansi, ndipo ina ndi njira yapadera ya calcium carbide ku China. Magwero a njira ya ethylene makamaka ndi mafuta, pomwe magwero a njira ya calcium carbide makamaka ndi malasha, miyala yamwala ndi mchere. Zinthu zimenezi zimapezeka kwambiri ku China. Kwa nthawi yayitali, njira ya PVC ya calcium carbide ku China yakhala ikutsogolera kwambiri. Makamaka kuyambira 2008 mpaka 2014, mphamvu ya PVC yopanga njira ya calcium carbide ku China yakhala ikukwera, koma yabweretsanso mavuto ambiri oteteza chilengedwe.

Kugwiritsa ntchito mphamvu kwa kupanga calcium carbide ndi kwakukulu kwambiri, kotero izi zibweretsa zovuta zina pamagetsi aku China. Chifukwa magetsi amapangidwa ndi malasha oyaka, amafunika kugwiritsa ntchito malasha ambiri, kotero kuyaka kwa malasha kudzaipitsa mlengalenga mosalekeza. Komabe, China yasintha mfundo zina pazaka zambiri. China ikukonzanso nthawi zonse unyolo wake wamafakitale. Tsopano tikutha kuwona kuti China yatumiza mafuta ambiri, ndipo mabizinesi am'deralo akulimbikitsidwa kuitanitsa mafuta kuti ayeretse zinthu zomwe zili pansi pa madzi. Chifukwa chake, m'zaka zaposachedwa, opanga angapo atsopano a ethylene process awonjezedwa ku China, ndipo mphamvu zonse zatsopano zopangira PVC ku China m'zaka zaposachedwa ndi mphamvu zopangira njira ya ethylene. Mphamvu zopangira njira ya calcium carbide yaku China yasiya kuvomerezedwa kwatsopano. Chifukwa chake, posachedwa, chiwerengero cha zomera za ethylene ku China chidzapitirira kuwonjezeka ndipo njira ya calcium carbide ipitiliza kuchepa. M'tsogolomu, kuchuluka kwa njira ya ethylene yotumizira kunja ku China kudzapitirira kuwonjezeka, ndipo pang'onopang'ono kukhala wogulitsa kunja kwambiri padziko lonse lapansi wa PVC.
