I kēia mau lā, ua hoʻololi hou ʻia ka nui o ka acetic acid, acetone, bisphenol A, methanol, hydrogen peroxide a me urea, e uhi ana ma kahi o 100 mau hui kemika me ka mana o 15 miliona mau tons, me ka mākeke kaʻa mai hoʻokahi pule a 50 mau lā. , a ʻaʻole hoʻolaha kekahi mau hui i ka manawa e hoʻomaka ai.

Acetic acid: ka mākeke acetic acid, kekahi mau hale hana kaʻa mālama ʻana, ua hoʻemi ʻia ka lako kahua.

Acetone: Blue Star Harbin Petrochemical 150,000 tons / year phenol ketone device i kēia manawa i ka hoʻomaka ʻana o ka mālama kaʻa ʻo ʻAukake, manaʻo ʻia ka mālama kaʻa ma kahi o 50 mau lā, e pili ana nā kikoʻī i ka hoʻokuʻu ʻana i ke kūʻai aku i ka wā kaʻa.

ʻO Bisphenol A: Yanhua polycarbonate 150,000 tons / makahiki bisphenol ʻO kahi mea kanu hoʻomaha no ka mālama ʻana, manaʻo ʻia aia ma kahi o hoʻokahi mahina.
ʻO Sinopec Sanjing 120,000 tons / makahiki bisphenol ʻO kahi mea kanu hoʻomaha no ka mālama ʻana, manaʻo ʻia ʻo ia ma kahi o hoʻokahi mahina.

PE: I ʻAukake, ʻo ka hana hale o nā mea paipu polyethylene i komo i ka hoʻokomo ʻana i kahi ʻoihana hikina hikina hou, Lanhua Yulin mea kanu mālama kaʻa, e pili ana i ka mālama ʻana i ka nui makahiki o 800,000 tons. Hoʻopaʻa ʻia ka hāmeʻa e pili ana i nā pūʻulu polyethylene 16, e like me Shanghai Petrochemical, Maoming Petrochemical, Yulin Chemical, Daqing Petrochemical a pēlā aku.

PVC: i kēia mahina Salt Lake magnesium, Henan Shenma, Hengyang Jiantao, Xinjiang Zhongtai, Ningbo Formosa e hoʻoponopono a hoʻomaka koke e hoʻoponopono, e pili ana i ka hiki ke oi aku ma mua o 4 miliona mau tona.

BDO: Henan Kaixiang August 10 overhaul no hoʻokahi mahina, Sichuan Tianhua ʻAukake 15 mālama kaʻa, Shaanxihua ʻAukake 20 pani pani, Lanshan Tunhe ʻAukake 23 ka nānā ʻana i ka makahiki, Shaanxi Black Cat ʻAukake 31 hoʻoponopono hou no hoʻokahi mahina, hoʻonui ʻia ka aila Sepatemaba 1 overhaul no hoʻokahi mahina, ʻO Yizheng Dalian Sepatemaba 1 overhaul, ʻāpana o ka hāmeʻa e mālama i ka hana ukana 6-7%.

PTA: Ma ka lā 26 o ʻAukake, he 68.2% ka hoʻomaka ʻana o ka PTA, Kina Hema, kahi hoʻolālā mua o 2 miliona tons o ka mea PTA e hoʻemi i ka maikaʻi ʻole i 70% i ka hoʻomaka ʻana o Kepakemapa, Kina Hikina, kahi hoʻonohonoho o 640,000 tons o nā mea PTA. ua hoʻonohonoho ʻia e hoʻomaha no ka mālama ʻana mai ka hoʻomaka ʻana o Sepatemaba, ua manaʻo ʻia e overhaul kokoke i 20 lā, ua manaʻo ʻia e PTA hoʻomaka haʻahaʻa hoʻomau i ka palena nui. ʻO Chuaneng chemical huahana makahiki o 1 miliona tons PTA mea kanu i ke ahiahi o ʻAukake 16 kaʻa, hoʻomaka hou ka manawa e hoʻoholo ai.

PDH: PDH loaʻa i kēia makahiki he poho, PDH hoʻomaka i ka manawa like o ka makahiki haʻahaʻa pae. Augate PDH loaʻa nō ka poho, hoʻomaka hoʻomau i ka malama i ka haʻahaʻa pae, August hou Donghua Energy Ningbo 800,000 tons o ka mea kanu a me Jineng Technology a me ka PDH mea kanu mālama.
ʻO ka Methanol: ʻO ka nui o ka hoʻohana ʻana i ka nui o ka methanol ma ke komohana hema o Kina he 53.43%, -14.02% i hoʻohālikelike ʻia me ka pule i hala. I kēia manawa, ua hoʻopau a mālama ʻia kekahi o kēia mau mea kanu methanol mai ʻAukake 13 a hiki i ʻAukake 16, a ʻo ka lōʻihi o ka mālama ʻia ʻana ma kahi o hoʻokahi pule.

ʻO ka phosphorus melemele: ʻo ka hapa ʻelua o ka mahina, ka palena o ka mana o Sichuan, nā kaʻa ʻoihana phosphorus melemele. ʻO Guizhou urnan wahi ma muli o ka hopena o ka maʻi maʻi hoʻopaʻa hoʻopaʻa 'ia, kekahi mau wahi o ka melemele phosphorus kaʻa kaʻa, hoʻohālikelike me ka mua i kekahi pilikia. ʻO kekahi mau hui ma ka ʻāina ʻo Yunnan i hoʻoponopono a hoʻokuʻu i nā makana.

Caprolactam: Zhejiang Juhua caprolactam ka mana o 100,000 tons, ʻAukake 18 mai ka mālama kaʻa ʻana no kahi hapalua mahina. He 400,000 tons o ka caprolactam ka Hui Kimia Haili; Loaʻa iā Shandong Haili he 200,000 tons caprolactam, a ua paʻa ka mea kanu. ʻO Jiangsu Dafeng 200,000 tons, kahi laina ma muli o ka mālama ʻana i nā mea kanu mana mai ʻApelila 1 hoʻomaha i ka mālama ʻana, hoʻomaka hou i ka lohi, kahi laina kaʻa i loko.

Urea: ma muli o ke kiʻekiʻe o ka mahana e hoʻomau nei, ʻAukake 13, ua hoʻomaka ʻo Sichuan Jiuyuan a me nā mea hana urea ʻē aʻe i ke kaʻa laina piha, ʻo Sichuan Lutianhua a me Tianhua nā mea hana i nā hola mua o ʻAukake 15 ua hoʻomaka ka kaʻa laina piha, e like me kēia manawa, kokoke i nā mea kanu urea a pau i loko. Ke kū nei ʻo Sichuan a me Chongqing, nā helu helu e pili ana i ka kaʻa a me ka hōʻemi ʻana o ka huina o 17 mau ʻoihana, ka pālākiō hana urea i kēlā me kēia lā 139,900 tons, 11,800 tona emi mai ka manawa like o ka makahiki i hala; ka helu hoʻomaka 62.67%, i lalo 7.67% mai 70.34% i ka manawa like i ka makahiki i hala.
No ka wā i hala, ʻo ʻAukake maʻamau ka hopena o ka manawa mālama, a ma hope o ia e hālāwai ai me ka "Golden Nine Silver Ten" koi wā kiʻekiʻe maʻamau. I kekahi olelo, i ka kiʻekiʻe wela a me ka ua i loko o August 'aʻole i kūpono no ka 'oihana huahana no ka nui-unauna overhaul, a me keia makahiki i hele mai ma mua e hele ma hope overhaul, apparently mau lōʻihi manawa, a me March-August kemika overhaul poho i loa concentrated, ua. i ka manawa like o ka makahiki kiʻekiʻe.

No ka mākeke kemika, ʻo ka hāʻawi ʻana a me ke koi he mea nui e pili ana i ke kumukūʻai, ʻo ka ʻaoʻao hoʻolako o ka hōʻemi e alakaʻi i ka hoʻopaʻa ʻana i ke kumukūʻai o nā waiwai, e hoʻonui ʻia nā kumukūʻai i ka wai. Akā ʻo ke kūlana i kēia makahiki, ʻaʻole i manaʻo maikaʻi ka mākeke o lalo, a ke hoʻomau nei ke kūʻai aku ʻana i ka home, ʻo ke kālepa ʻana o nā ʻāina ʻē a kokoke i stagnant, ua ulu aʻe ka pani ʻana o ka hale hana i lalo mai kekahi mau lā, he mau pule i 3 mahina, hapalua makahiki. o ka hoomaha. ʻO kēia kūlana "hoʻopau" i lalo, akā ua hoʻoholo hoʻi i ka upstream o ke kaulahao ʻoihana o nā ʻoihana kemika ʻaʻole e waiwai nui, a loaʻa pū i ka pahele "thicken ʻaʻole e hoʻonui i ka waiwai". He ʻoi aku ka nui o ka mālama ʻana i lalo ma mua o ka upstream, a ua koi hou ʻia i ka ʻoki ʻana i ka upstream production a me ka mālama ʻana.

A laila, ʻoki ʻia kēia hana nui no ka wā lōʻihi, inā paha e lawe mai ia i ka "kumukūʻai paʻa" a me ka hoʻopaʻa ʻana i ke kūlana wela, a i ʻole i ke au hoʻomaha o lalo i hoʻoikaika ʻia i loko o kahi moe moe paʻa, nā kumukūʻai ikaika a me nā koi nāwaliwali ʻelua kaomi ma lalo o ka ʻoihana kemika a pehea e ulu ai, e hoʻomalu ʻia e ka hopena o ka hāʻawi ʻana a me ka koi ʻana i nā hopena pāʻani.

KemwinHe ʻoihana kālepa ʻenehana ma Kina, aia ma Shanghai Pudong New Area, me kahi pūnaewele o nā awa, nā terminals, nā mokulele a me nā kaʻa kaʻaahi, a me nā hale kūʻai kemika a me nā mea weliweli ma Shanghai, Guangzhou, Jiangyin, Dalian a me Ningbo Zhoushan, Kina , mālama ʻoi aku ma mua o 50,000 tons o nā mea maka kemika a puni ka makahiki, me ka lako lako, hoʻokipa e kūʻai a nīnau. chemwinleka uila:service@skychemwin.comwhatsapp: 19117288062 Tel: +86 4008620777 +86 19117288062
