Ma hope o ke komo ʻana i ka mahina ʻo Kepakemapa, ʻo ka mākeke kūloko o PVC mai ka piʻi haʻahaʻa haʻahaʻa haʻahaʻa, ma hope o ke kakahiaka a hiki i ka waena i hāʻule i loko o ka haunaele, e like me ka nehinei a me ke ʻano ethylene o PVC ma ke ʻano calcium carbide ka mākeke aupuni no ka awelika o 6375 yuan/ton a me 6681 yuan/ton, a me ka mākeke o kēia lā e mau ana ma lalo o ke kaomi iho, akā ʻo ka lalo o ke kahawai e lawe i nā kūlana i ka haʻahaʻa o ka noʻonoʻo ʻoi aku ka maopopo.Manaʻo ka loiloi he ʻoi aku ka paʻakikī o ka mākeke PVC e loaʻa ai ka hoʻomaikaʻi ʻana, ʻoi loa ma muli o ka nāwaliwali o ka noi o lalo, ʻaʻole i hoʻokaʻawale maikaʻi ʻia ka waihona waiwai, me ka haʻahaʻa o ke kumukūʻai mākeke honua, ʻaʻole kūpono i ka lawe ʻana aku i kā mākou huahana a pēlā aku. .

1. ʻAʻole lawa ke kākoʻo koi a me ka waihona kiʻekiʻe.Ma hope o ke komo ʻana i loko o Kepakemapa, ʻo ka hale i lalo o ke kūkulu ʻana o PVC e hoʻomaikaʻi i ka piʻi ʻana i manaʻo ʻia, akā ʻo ke kūlana o kēia manawa o ka manaʻo, ma waho aʻe o ka hana ʻoi aku ka maikaʻi o nā kiʻiʻoniʻoni a me nā huahana palupalu ʻē aʻe, a me nā mea kūkulu hale pili pili, hoʻomaka ka hoʻomaka ʻana o ka paipu, no laila. ʻO ka mea kūʻai liʻiliʻi koho e "kūʻai" piʻi me ka hoʻohana nui ʻana i ka hoʻohana ʻana i ke koʻikoʻi ma luna, ʻoihana nui ma ka hoʻohui ʻana i ke kūʻai maʻamau, i kekahi manawa i ka dips a me ka hoʻokahi, Akā, ua lohi ka nui o ka waihona kiʻekiʻe ma ka mākeke digestion.

2. Mea maka.ʻO ke kumukūʻai kūʻai o ka calcium carbide i kēia manawa ma ke komohana ʻākau o Kina, ka wahi hana nui, ʻo 3650-3850 yuan / ton, a ʻo ke kumukūʻai o ka calcium carbide ma North China he 3980-4140 yuan / ton.Ma ke ʻano holoʻokoʻa, ʻaʻohe kumu kūʻai liʻiliʻi no nā ʻoihana hana PVC e kūʻai ana i ka calcium carbide.Ma ke ʻano o ka ethylene maka, ʻo ke kumu kūʻai awelika o ka ethylene CFR ma Asia Hikina Hikina he 970 kālā/ton, a ʻo ke kumu kūʻai maʻamau o CFR ma Asia Hema he 960 kālā/ton.Ua hoemiia ke kumukuai o Asia Hikina Hema i ka hoohalikeia me ke kumu kuai mua.

3. ʻAʻole ikaika ka mākeke kūʻai aku, a ua hāʻule ke kumukūʻai o ke kālepa ʻana i nā ʻāina ʻē.I Iulai i kēia makahiki, ua lawe aku ʻo Kina i 177,000 tons o ka pauka maʻemaʻe PVC, ʻo 20.8% ka liʻiliʻi ma mua o ka mahina i hala.I kēia manawa, ʻoiai ke hoʻomau nei ka nui o ka hoʻokuʻu ʻana aku i hoʻokahi mahina o PVC ma Kina i kahi pae kiʻekiʻe, aia kahi hiʻohiʻona i lalo no 3 mau mahina, a ua hoʻemi mau ʻia ke kumukūʻai mākeke PVC honua hou, kahi i nāwaliwali ke kākoʻo o makeke kalepa kūloko.

4. Hoʻopili ʻia e ka mākeke o ka wā e hiki mai ana.I kēia mau lā, ua hāʻule nui nā kumukūʻai o PVC i ka wā e hiki mai ana, i hoʻopilikia ʻia e kēia, ʻike ʻia ka mākeke wahi e hahai i ka hanana.ʻO ka wā e hiki mai ana i kēia lā he concussion haʻahaʻa haʻahaʻa, ʻoi aku ka nui o ke kali ʻana a me ka ʻike.
