I ka hapaha ʻekolu, ʻo ka hapa nui o nā huahana i loko o ke kaulahao ʻoihana acetone o Kina i hōʻike i kahi ʻano piʻi piʻi. ʻO ka mea hoʻoikaika nui o kēia ʻano ka hana ikaika o ka mākeke aila ʻaila honua, a ʻo ia hoʻi ka mea i alakaʻi i ke ʻano ikaika o ka mākeke o ka upstream raw material, ʻoi aku ka nui o ka piʻi nui ʻana o ka mākeke benzene maʻemaʻe. Ma kēia kūlana, ʻo ka ʻaoʻao kumu kūʻai o ke kaulahao ʻoihana acetone ka mea e hoʻonui ai i ke kumukūʻai, ʻoiai ʻaʻole liʻiliʻi nā kumu hoʻopuka acetone, ʻoi aku ka haʻahaʻa o ka ʻoihana phenol ketone, a paʻa ka lako wahi. Ke kākoʻo pū nei kēia mau mea i ka hana ikaika o ka mākeke. I loko o kēia hapaha, ʻo ke kumukūʻai kiʻekiʻe o ka acetone ma ka mākeke ʻo Kina Hikina ma kahi o 7600 yuan no ke tona, aʻo ke kumu kūʻai haʻahaʻa he 5250 yuan no ke tona, me ka ʻokoʻa o ke kumu kūʻai o 2350 yuan ma waena o ka hopena kiʻekiʻe a me ka haʻahaʻa.

E noʻonoʻo kākou i nā kumu e piʻi mau ai ka mākeke acetone kūloko i ke kolu o ka hapaha. I ka hoʻomaka ʻana o Iulai, ʻo ke kulekele o ka ʻauhau ʻana i ka ʻauhau ma luna o kekahi mau mea ʻaila maka i mālama ʻia nā kumukūʻai o nā kumu waiwai paʻa, a ua ikaika loa ka hana o ka benzene maʻemaʻe a me ka propylene. Ua ʻike pū nā mākeke o lalo no ka bisphenol A a me ka isopropanol i nā pae like ʻole o ka hoʻonui. Ma lalo o ke kaiapuni mahana holoʻokoʻa, ʻike pinepine ka mākeke kemika kūloko i ka piʻi. Ma muli o ka haʻahaʻa haʻahaʻa o ka 650000 ton phenol ketone plant ma Jiangsu Ruiheng a me ka paʻa o ka acetone, ua hoʻonui nui nā mea hoʻolako i nā waiwai i kā lākou kumukūʻai. Ua alakaʻi pū kēia mau mea i ka piʻi ikaika o ka mākeke. Eia naʻe, e hoʻomaka ana mai ʻAukake, ua hoʻomaka e nāwaliwali ka noi o lalo, a ua hōʻike nā ʻoihana i nā hōʻailona o ka nāwaliwali i ka hoʻoulu ʻana i nā kumukūʻai, a aia ke ʻano o ka hāʻawi ʻana i nā loaʻa. Eia nō naʻe, ma muli o ka mākeke ikaika no ka benzene maʻemaʻe, ke mālama nei ʻo Ningbo Taihua, Huizhou Zhongxin, a me Bluestar Harbin phenol ketone mea kanu. ʻO Jiangsu Ruiheng's 650000 tons phenol ketone plant i manaʻo ʻole ʻia i kū i ka lā 18, kahi i loaʻa ka hopena maikaʻi i ka manaʻo mākeke a ʻaʻole ikaika ka makemake o nā ʻoihana e haʻalele i ka loaʻa kālā. Ma lalo o ka interweaving o nā kumu like ʻole, ʻike nui ʻia ka mākeke e ka fluctuations interval.

Ma hope o ke komo ʻana o Kepakemapa, hoʻomau ka mākeke i ka ikaika. ʻO ka piʻi mau ʻana o ka mākeke aila ʻaila honua, ke ʻano ikaika o ke kaiapuni holoʻokoʻa, a me ka ulu ʻana o ka mākeke benzene maʻemaʻe maka i alakaʻi i ka piʻi nui o nā huahana o ke kaulahao ʻoihana phenolic ketone. ʻO ka ikaika mau o ka bisphenol lalo A ua hoʻoikaika ka mākeke i ka noi maikaʻi no ka acetone, a ua lawe nā mea hoʻolako i nā waiwai i kēia manawa e hoʻonui i nā kumukūʻai a hoʻoulu i ka ulu ʻana o ka mākeke. Eia kekahi, ʻaʻole kiʻekiʻe ka waihona o ke awa, a ke mālama nei nā mea kanu Wanhua Chemical a me Bluestar Phenol Ketone. Ke hoʻomau nei ka hāʻawi ʻana i kahi kikoʻī, me ka nui o ke kahawai i ka hahai ʻana i ke koi. ʻO kēia mau mea i hoʻoikaika pū i ka piʻi mau ʻana o nā kumukūʻai mākeke. Ma ka hopena o ke kolu o ka hapaha, ʻo ke kumukūʻai pani o ka mākeke acetone East China he 7500 yuan no ton, he piʻi o 2275 yuan a i ʻole 43.54% i hoʻohālikelike ʻia i ka hopena o ka hapaha mua.

Eia nō naʻe, manaʻo ʻia e hiki ke hoʻopaʻa ʻia ka loaʻa hou ʻana o ka mākeke acetone ma Kina Hikina i ka hapahā ʻehā. I kēia manawa, haʻahaʻa ka waihona o nā awa acetone, a paʻa iki ka lako holoʻokoʻa, me nā kumu kūʻai. Eia nō naʻe, paʻakikī paha i ka ʻaoʻao kumukūʻai e loaʻa hou i kahi pahu ikaika. Ma hope o ke komo ʻana i ka hapahā ʻehā, e hoʻopili ʻia ka hana ʻana o nā ketone phenolic hou, a e hoʻonui nui ʻia ka lako. ʻOiai ʻoi aku ka maikaʻi o ka loaʻa kālā o ka phenolic ketones, koe wale nō nā ʻoihana e mālama mau ana, e mālama nā ʻoihana ʻē aʻe i ka hana kiʻekiʻe. Eia nō naʻe, ʻo ka hapa nui o nā ʻāpana ketone phenolic hou i lako me nā ʻāpana bisphenol A i lalo, no laila he liʻiliʻi ke kūʻai ʻana o waho o ka acetone e nā ʻoihana o lalo e hoʻohana ana ia mea. Ma ke ʻano holoʻokoʻa, manaʻo ʻia i ka hapaha mua o ka hapahā, hiki ke loli a hoʻohui ʻia ka mākeke acetone kūloko; Akā i ka piʻi ʻana o ka lako, hiki ke nāwaliwali ka mākeke i nā pae hope.
