Ma ke ʻano o ka hoʻolako ʻana, ʻo ka calcium carbide, i ka pule i hala, ua hoʻemi ʻia ke kumukūʻai mākeke nui o ka calcium carbide ma 50-100 yuan / ton. Ua paʻa ka ukana hana holoʻokoʻa o nā ʻoihana calcium carbide, a ua lawa ka lako o nā waiwai. Ma muli o ka maʻi ahulau, ʻaʻole maʻalahi ka lawe ʻana o ka calcium carbide, ua hoʻohaʻahaʻa ʻia ke kumukūʻai hale hana o nā ʻoihana e ʻae i ka lawe ʻana i ka loaʻa kālā, nui ke kaomi kumukūʻai o ka calcium carbide, a manaʻo ʻia e kaupalena ʻia ka emi ʻana o ka wā pōkole. Ua hoʻonui ʻia ka ukana hoʻomaka o nā ʻoihana PVC ma uka. Hoʻopili ʻia ka mālama ʻana o ka hapa nui o nā ʻoihana i ka waena a me ka hopena o ʻApelila, a e mau ana ke kaumaha hoʻomaka kiʻekiʻe i ka wā pōkole. Ma muli o ka maʻi ahulau, ua haʻahaʻa ka ukana hana o nā ʻoihana kūloko ma lalo, ua nāwaliwali ke koi, a ua hoʻonui ʻia ka waihona o kekahi mau ʻoihana hana PVC ma kahi o ka hale hana ma muli o ka halihali maikaʻi ʻole.
Ma ʻApelila 6, ʻaʻole i loli nui ke kumukūʻai o ka PVC ma ʻĀsia i kēia pule. Ke noho nei ʻo CFR Kina ma US $1390 / ton, ke noho nei ʻo ʻĀsia Hikina Hema ma US $1470 / ton, a hāʻule ʻo CFR India ma US $10 i US $1630 / ton. Ua kūpaʻa ke kumukūʻai kiko o ka mākeke waho, akā ua nāwaliwali ka hoʻokuʻu aku ma mua o kēlā i ka wā mua ma muli o ka nāwaliwali mau o ka ʻaila maka honua. Ma ʻApelila 7, ua hōʻike ka ʻikepili hebedoma he 82.42% ka ukana hana holoʻokoʻa o PVC, me ka piʻi ʻana o 0.22 pakeneka i kēlā me kēia mahina; I waena o lākou, ʻo 83.66% ka ukana hana o ka calcium carbide PVC, i lalo he 1.27 pakeneka i kēlā me kēia mahina.
Ua loaʻa iā Chemdo nā nīnau mai Asia Hikina Hema, ka Hikina Waena a me ʻApelika i hala koke aku nei, a ua kūpaʻa nō ka hoʻokuʻu aku ʻana.
