1.Kusanthula kwamtundaasidi asidimayendedwe a msika

Mtengo wa acetic acid kumayambiriro kwa mwezi unali 3235.00 yuan / tani, ndipo mtengo kumapeto kwa mwezi unali 3230.00 yuan / tani, kuwonjezeka kwa 1.62%, ndipo mtengo unali 63.91% wotsika kuposa chaka chatha.

Mu Seputembala, msika wa acetic acid udalamulidwa ndi mitundu yosiyanasiyana ya oscillation, pomwe mitengo idatsika isanakwere. Mu theka loyamba la chaka, msika wa asidi acetic unali wophatikizana, wokhala ndi zokwanira zokwanira, kufunikira kochepa kwapansi pamtsinje, kufooka kwa msika ndi kufunikira, mitengo ya acetic acid inasinthasintha; mu theka lachiwiri la chaka, msika wa asidi acetic unali wofooka komanso wotsika, makamaka chifukwa mabizinesi osamalira asidi a acetic adayambanso kugwira ntchito bwino, kupezeka kwa msika kunali kokwanira, kugula kwapansi kwa mtsinje kunapitirira kukhala kofooka, kupereka kunali kolimba komanso kofooka, acetic. mitengo ya asidi inapitirizabe kutsika; Pakutha kwa mweziwo, tchuthi cha Tsiku Ladziko Lonse chinali kuyandikira, kufunikira kwa masitomu akutsika kumawonjezeka, ndipo mabizinesi anali ndi cholinga chokweza mitengo. Kumapeto kwa mweziwo, kuperekedwako kunakwera, kutsatiridwa ndi kuwonjezeka kwa mtengo wa methanol kumtunda, chithandizo cha zinthu zopangira ndi chabwino, kumapeto kwa mwezi mitengo ya acetic acid idakwera mpaka kumayambiriro kwa mwezi.

2. ethyl acetate kusanthula kwa msika

Mu Seputembala, ethyl acetate yapakhomo ikadali yofooka, msika udakalipobe. Malinga ndi ziwerengero za Business News Service, kuchepa kwa mwezi uno kunali 0.43%, ndipo kumapeto kwa mweziwo, mtengo wamsika wa ethyl acetate unali 6700-7000 yuan / ton.

Mwezi uno, mbali ya mtengo wa ethyl acetate si yabwino kwambiri, asidi acetic ambiri pamwezi oscillating pansi, sabata yapitayi ya September inakulanso, zomwe zimatsogolera ku nthawi yochepa ya ethyl acetate mmwamba, kutha kwa mwezi sikungatheke. mitengo akadali sanabwerere ku chiyambi cha mlingo. Panali kusintha pang'ono kumbali yoperekera katundu, zomera zambiri ku East China zinkayenda bwino, ndipo mphamvu zotumizira mabizinesi sizinayambitse nyengo yapamwamba ya "Golden Nine", ndipo zosungirako zidakhalabe zapamwamba. Kusintha kwamitengo yamitengo yayikulu ku Shandong sikofunikira. Kufooka kwa msika wapansi panthaka kumakhala kovuta kuwongolera, ndipo kugula kumakhalabe kokhazikika pakungofuna.

3.butyl acetate msika wamakono kusanthula

Domestic butyl acetate idapitilirabe mu Seputembala, ndipo msika udali wofooka. Malinga ndi Business Newswire, kutsika kwa mwezi kwa butyl acetate kunali 2.37%. Kumapeto kwa mwezi, mtengo wapakhomo wa butyl acetate unali 7,200-7,500 yuan/ton.

Kumbali imodzi, mbali ya mtengowo idasiyana, ngakhale kuti asidi acetic adabweranso kumapeto kwa mweziwo, komabe zovuta kuthamangitsa kutsika kwa butyl acetate mumdima, chinthu china chakumtunda n-butanol kugwedezeka pansi, kutsika ndi 2.91% pamwezi. . Ponseponse, mbali yamtengo wapatali ikadali yolamulidwa ndi mbali yaifupi. Mtengo wanthawi yayitali wa butyl acetate makamaka umachokera ku kukakamizidwa kwa kaphatikizidwe ndi kufunikira: momwe chipangizocho chimayambira, mabizinesi a butyl amasintha pang'ono, kuchuluka koyambira kwa mbewu zazikulu kuti zisungidwe kumtunda ndi kumtunda. kuchepetsa 40%, koma kukakamiza kwazinthu za zomera zazikulu ndi zoonekeratu, chifukwa cha kufunikira kofooka, malonda a msika si abwino. The terminal amangofuna basi, ndipo msika wonse wamalonda ndi wopepuka.

4.Analysis wa acetic acid industry unyolo

Kuchokera kufananiza tchati cha kukwera ndi kugwa kwa unyolo wa acetic acid, titha kuwona kuti unyolo wamakampaniwo ukuwonetsa kuzizira pamwamba ndi kutentha pansi, ndi methanol (19,17%) kumapeto kwa gwero kukukwera kwambiri, kuyika kupsinjika kwakukulu pa asidi acetic ndi kunsi kwa mtsinje. Makamaka, kutsika kwa ethyl ester ndi butyl ester akadali omasuka ku msika woipa. Phindu losiyanitsidwa ndi mabizinesi m'mweziwo lidapangitsanso kuti oyambitsa ayambe kukhala otsika, ndikuchotsa koyipa makamaka.

M'kanthawi kochepa, makampani a acetic acid adzakhalabe ofooka, opanga ma asidi a acetic akhoza kudziunjikira masheya panthawi yatchuthi, koma masheya otsika a ethyl acetate, butyl acetate ndi PTA akupitilizabe kudyedwa pa chikondwererochi, komanso kubwezeredwa kwa msika pambuyo pake. chikondwererocho chidzabweretsa phindu kwa acetic acid. Komabe, poganizira kusintha pang'ono pakufunika komaliza. Ethyl ester ndi mitengo ya butyl ester ikhoza kukhalabe yofooka.

Chemwinindi kampani yopanga mankhwala opangira mankhwala ku China, yomwe ili ku Shanghai Pudong New Area, yokhala ndi madoko, malo okwerera ndege, ma eyapoti ndi zoyendera njanji, komanso malo osungiramo mankhwala owopsa komanso owopsa ku Shanghai, Guangzhou, Jiangyin, Dalian ndi Ningbo Zhoushan, China. , kusunga matani oposa 50,000 a mankhwala opangira mankhwala chaka chonse, ndi katundu wokwanira, olandiridwa kugula ndi kufunsa. chemwin email:service@skychemwin.comwhatsapp: 19117288062 Tel: +86 4008620777 +86 19117288062
