Mu rwego rwo gutanga ibintu, kariside ya calcium, icyumweru gishize, igiciro rusange cyisoko rya calcium karbide yagabanutseho 50-100 yuan / toni.Umutwaro rusange wibikorwa bya calcium karbide yinganda byari bihagaze neza, kandi gutanga ibicuruzwa byari bihagije.Ingaruka z’icyorezo, ubwikorezi bwa kariside ya calcium ntabwo bworoshye, igiciro cyuruganda rwibigo cyaragabanutse kugirango yemererwe gutwara inyungu, umuvuduko wibiciro bya kariside ya calcium nini, kandi biteganijwe ko igabanuka ryigihe gito rizaba rito.Umutwaro wo gutangiza imishinga ya PVC yo hejuru wiyongereye.Kubungabunga ibigo byinshi byibanze hagati na nyuma ya Mata, kandi imitwaro yo gutangira izakomeza kuba ndende mugihe gito.Bitewe n’iki cyorezo, umutwaro w’ibikorwa by’imishinga yo mu gihugu uri hasi ni muto, ibisabwa ni bike, kandi ibarura ry’inganda zimwe na zimwe zitanga umusaruro wa PVC mu karere k’uruganda ryiyongereye kubera ubwikorezi buke.
Kuva ku ya 6 Mata, igiciro cya PVC muri Aziya nticyahindutse cyane muri iki cyumweru.CFR Ubushinwa buguma kuri US $ 1390 / toni, Aziya yepfo yepfo yepfo ikomeza kuba US $ 1470 / toni, naho CFR Ubuhinde bugabanuka US $ 10 kugeza US $ 1630 / toni.Igiciro cy’isoko ryo hanze cyagumye gihamye, ariko ibyoherezwa mu mahanga byari bifite intege nke ugereranije n’icyiciro cya mbere kubera intege nke za peteroli mpuzamahanga ikomeje.Kugeza ku ya 7 Mata, amakuru ya buri cyumweru yerekanaga ko umutwaro rusange wa PVC wari 82.42%, ukwezi ku kwezi kwiyongeraho 0.22 ku ijana;Muri byo, umutwaro wa calcium karbide PVC wari 83,66%, wagabanutseho amanota 1.27 ku kwezi.
Chemdo yakiriye ibibazo byaturutse mu majyepfo y'uburasirazuba bwa Aziya, Uburasirazuba bwo hagati na Afurika, kandi ibyoherezwa mu mahanga biracyahagaze neza.
