Ma lalo o ka mana o ka Federal Reserve a i ʻole ka piʻi ʻana o ka uku pānaʻi radical, ua ʻike ke kumukūʻai aila honua i nā piʻi nui a i lalo ma mua o ka ʻahaʻaina.Ua hāʻule ke kumu kūʻai haʻahaʻa ma kahi o $81/barela, a laila hoʻihoʻi hou aʻe.ʻO ka loli ʻana o ke kumukūʻai aila maʻemaʻe e pili pū ana i ke ʻano o nā mākeke glycerol a me phenol ketone.

ʻO BisphenolA:
Kumukūʻai: Ua hoʻomau ka piʻi ʻana o ka mākeke bisphenol A: mai ka lā 12 o Kepakemapa, ʻo ke kumukūʻai kuhikuhi o bisphenol A ma Kina Hikina he 13500 yuan/ton, ʻoi aku ka 400 yuan mai ka pule i hala.
Ma muli o ka piʻi ʻana o ke kumukūʻai o ka benzene maʻemaʻe, ka pani ʻana o nā mea kanu phenol a me ketone o Zhejiang Petrochemical, a me ka piʻi ʻana o ke kumukūʻai papa inoa o nā ʻoihana petrochemical mainstream, ua piʻi nui ka mākeke phenol a me ketone ma mua o ka ʻahaʻaina.Ua piʻi ke kumu kūʻai o phenol i kahi kiʻekiʻe o 10200 yuan/ton, a laila emi iki.
Ma mua o ka ʻahaʻaina, ua nāwaliwali nā mākeke PC a me ka epoxy resin ma lalo o ka bisphenol A, a ʻaʻole i loli nui nā kumu.Ua piʻi iki ka mākeke bisphenol A, i alakaʻi ʻia e ke kākoʻo hoʻonui ʻia o ka phenol ketone maka a me ka piʻi ikaika o Zhejiang Petrochemical Bisphenol A kūʻai.
Ma hope o ka ʻahaʻaina, piʻi mau ka mākeke bisphenol A, a ua hoʻololi ʻia nā ʻōlelo a nā mea hana nui ma East China, Changchun Chemical a me Nantong Xingchen, i 13500 yuan / ton.
Ma ke ʻano o nā mea maka, ua piʻi mua ka mākeke phenol ketone a hāʻule i ka pule i hala: ʻo ke kumu kūʻai hou o ka acetone he 5150 yuan/ton, 250 yuan ke kiʻekiʻe ma mua o ka pule i hala;ʻO ke kumu kūʻai hou o ka phenol he 9850 yuan/ton, 200 yuan ke kiʻekiʻe ma mua o ka pule i hala.
Nā kūlana ʻāpana: Ua pani ʻia ka ʻāpana polycarbonate 180000 o Yanhua no ka mālama ʻana no hoʻokahi mahina mai ka lā 15, ua pani ʻia ka pūnāwai ʻekolu o Sinopec 120000 tons no ka mālama ʻana i hoʻokahi mahina mai ka lā 20, a ua hoʻomaka hou ka hui ʻana o Huizhou Zhongxin 40000 tons;ʻO ka helu holoʻokoʻa holoʻokoʻa o nā mea hana ʻenehana ma kahi o 70%.

epoxy resin
Kumukūʻai: ma mua o ka ʻahaʻaina, hāʻule mua ka mākeke epoxy resin a laila ala aʻe: mai ka lā 12 o Kepakemapa, ʻo ke kumu kūʻai o ka resin epoxy wai ma Kina Hikina he 18800 yuan/ton, a ʻo ke kumu kūʻai o ka resin epoxy paʻa he 17500 yuan/ ton, ʻo ia ka mea like me ka pule i hala.
Hoʻoikaikaʻia e ka pilina ma waena o ka lako a me ka noi, ua piʻi nui ka mākeke phenol a me ketone ma mua o kaʻahaʻaina, a ua hoʻi ke kumu kūʻai o ka phenol i kahi kiʻekiʻe ma mua o 10000 yuan, aʻo ia hoʻi i alakaʻi i ke kumukūʻai o bisphenol A e hoʻomau i ka piʻi;Ma hope o ke kumu kūʻai o ka epichlorohydrin, kekahi mea maka, ua hāʻule i kahi haʻahaʻa haʻahaʻa, ua hoʻonui ʻia ka nui o ka heluhelu ʻana a me ka hoʻopiha hou ʻana o ka hale hana resin, a hoʻomaka ke kumukūʻai.Ma hope o ka hoʻohaʻahaʻa ʻia ʻana o ke kumukūʻai o ka resin epoxy me ke kumukūʻai, ua piʻi iki ke kumukūʻai o ka resin paʻa a me ka wai i nā lā ʻelua i hala ma mua o ka ʻahaʻaina me ka piʻi mau ʻana o ka bisphenol A a me ka rebound o ka epoxy chloride.
I ka hoʻi ʻana i ka mākeke ma hope o ka ʻahaʻaina, e like me ke kakahiaka o Kepakemapa 13, ua paʻa ke kumukūʻai o ka wai a me ka resin epoxy paʻa no kekahi manawa, akā me ke kumukūʻai o ka bisphenol A e piʻi mau ana a me ka hoʻoponopono ʻana i nā hale hana nui ma Kina Hikina, ʻo ka wai. Ua hōʻike pū ka mākeke resin epoxy i kahi ʻano piʻi mua.
Ma ke ʻano o nā mea hana: ʻo ka nui o ka hana o ka resin wai ma kahi o 70%;ʻO ka helu hana holoʻokoʻa o ka resin paʻa he 4-50%.
