Mchitidwe Wa PVC, Mchitidwe Wa Carbide PVC Ndi Ethylene PVC

PVC ndi mtundu wa pulasitiki ntchito kwambiri mu zomangira. Chifukwa chake, sichidzasinthidwa kwa nthawi yayitali m'tsogolomu, ndipo idzakhala ndi chiyembekezo chogwiritsa ntchito m'malo osatukuka kwambiri mtsogolo.

Monga tonse tikudziwa, pali njira ziwiri zopangira PVC, imodzi ndi njira yapadziko lonse ya ethylene, ndipo ina ndiyo njira yapadera ya calcium carbide ku China. Magwero a njira ya ethylene makamaka mafuta a petroleum, pamene magwero a njira ya calcium carbide ali makamaka malasha, miyala yamchere ndi mchere. Zida izi zimakhazikika ku China. Kwa nthawi yayitali, njira yaku China ya PVC ya calcium carbide yakhala ikutsogola kwambiri. Makamaka kuyambira 2008 mpaka 2014, njira yaku China yopanga PVC ya calcium carbide yakhala ikuwonjezeka, koma yabweretsanso zovuta zambiri zoteteza chilengedwe.

Kugwiritsa ntchito mphamvu kwa calcium carbide ndikwambiri, chifukwa chake izi zidzabweretsa zovuta kumagetsi aku China. Chifukwa magetsi amapangidwa ndi malasha, amafunika kuwononga malasha ambiri, motero kuyaka kwa malasha kumawononga mlengalenga. Komabe, China yasinthanso ndondomeko pazaka zambiri. China ikupitilizabe kupititsa patsogolo bizinesi yake yamakampani. Tsopano titha kuwona kuti China idatumiza mafuta ochulukirapo, ndipo mabizinesi am'deralo akulimbikitsidwa kuitanitsa mafuta kuti ayese mafuta otsika. Chifukwa chake, m'zaka zaposachedwa, opanga njira zingapo za ethylene awonjezedwa ku China, ndipo mphamvu zonse zatsopano zopangira PVC ku China m'zaka zaposachedwa ndi mphamvu yopanga ethylene. Kupanga kwa njira yaku China ya calcium carbide kwayimitsa kuvomerezedwa kwatsopano. Choncho, posachedwapa, chiwerengero cha zomera za ethylene ku China chidzapitirira kuwonjezeka ndipo njira ya calcium carbide idzapitirira kuchepa. M'tsogolomu, China kuchuluka kwa katundu wa ethylene ndondomeko adzapitiriza kuwonjezeka, ndipo pang'onopang'ono kukhala kutsogolera padziko lonse wa ethylene ndondomeko PVC.
