M'gawo loyamba ndi lachiwiri, msika wa bisphenol A wapakhomo ndi wofooka, mu June udatsika mtengo watsopano wazaka zisanu wa 8700 yuan / tani, koma m'gawo lachitatu, bisphenol A idayambitsa kukwera kosalekeza munthawi yowunikira. , mtengo wamsika unakweranso kufika pamlingo wapamwamba kwambiri wa 12,050 yuan/ton chaka chino. Komabe, mitengo inakwera kufika pamlingo waukulu, kufunikira kwa kunsi kwa mitsinje kunatsatira ndi kufooketsedwa, ndipo msika unalowanso m’malo ododometsa.

Pofika kumapeto kwa Seputembala 2023, mtengo wokambitsirana wa East China bisphenol A msika uli pafupifupi 11,500 yuan/tani, kukwera 2,300 yuan/tani kuyambira kuchiyambi kwa Julayi, chiwonjezeko cha 25%; Mtengo wamsika wapakati pagawo lachitatu unali 10,763 yuan/ton, kukwera 13.93% kuchokera kotala yapitayo ndi kutsika 16.54% kuchokera nthawi yomweyi chaka chatha.

Gawo loyamba - Julayi: msika wa bisphenol A umapereka mtundu wa "N".

Kumayambiriro kwa Julayi, pambuyo pakuwonongeka kopitilira muyeso koyambirira, kuchuluka kwa zinthu zoyendera za bisphenol A sikunali kwakukulu, opanga ndi ogulitsa adathandizira msikawo, ndipo mafunso ena a PC kumunsi ndi apakati anali kubwezeretsanso, zomwe zidalimbikitsa msika wa bisphenol A kuchokera ku 9200. yuan/tani mwachangu kufika pa yuan 10,000/tani, pomwe msika wa Zhejiang Petrochemical wamitundu ingapo udakwera kwambiri, komanso adalowetsamo chidwi pamsika. Mtengo wapakati ndi wokwera, gawo lakumunsi la kubwezeretsanso pambuyo pa chimbudzi, bisphenol Mkhalidwe wamalonda wamsika wafooka. Chakumapeto kwa chaka, omwe ali ndi bisphenol A amatenga phindu, kuphatikizira kutsika kwamphamvu kwamphamvu, bisphenol A kugulitsa malo sikuli kosalala, ochita malonda ena ndi opanga kuti apange phindu kuti atumize, zokambirana zaku East China zidagwera pa 9600-9700 yuan/ton. . Mu theka lachiwiri la chaka, zinthu ziwiri zopangira phenol acetone zidakwera kwambiri, ndikukankhira mtengo wa bisphenol A kukwera, ndipo kukakamiza kwa opanga kunakula, ndipo mtengowo unayamba kukwera kumapeto kwa mweziwo, ndipo bisphenol A. kutsatira kukwera mtengo.

Gawo II - Kumayambiriro kwa Ogasiti - Pakati mpaka kumapeto kwa Seputembala: Msika wa bisphenol A ukupitilizabe kubwereranso pamlingo wapamwamba kwambiri mpaka pano chaka chino.

Kumayambiriro kwa Ogasiti, motsogozedwa ndi kukwera kwamphamvu kwa phenol ndi acetone, mtengo wamsika wa bisphenol A unali wokhazikika komanso wokwera, ndipo zida za bisphenol A zidakhazikitsidwa pakati kukonza pa siteji, Nantong Star, Huizhou Zhongxin, Luxi Chemical, Jiangsu Ruiheng. , Zida za Wanhua Chemical ndi Zhejiang Petrochemical phase II zonse zidayimitsidwa mu Ogasiti, ndipo msika udatsika; Ndipo podziwa zoyambira zoyambira, kunsi kwa mtsinje kumangofunika kubwezeretsanso mayendedwe otsata ndikwabwino. Mtengo, kupezeka ndi kufunikira kwapamwamba kwambiri, bisphenol A kukwera kwamakampani pamsika; Kumayambiriro kwa mwezi wa September, ntchito yapadziko lonse yamafuta amafuta imakhala yamphamvu, motsogozedwa ndi benzene yoyera, phenol acetone ikupitilira kukwera, bisphenol A ikukwera, zopatsa opanga zikupitilira kukwera, ndipo malo amsika akusokonekera. mmwamba, mkatikati mwa Seputembala, mtengo wamsika unakwera kufika pamlingo wapamwamba kwambiri chaka chino 12,050 yuan/ton.

Gawo lachitatu - pakati pa kumapeto kwa September - kumapeto kwa mwezi: msika wa bisphenol A msika unagwa.

Pakatikati ndi kumapeto kwa mwezi wa September, pamene mtengo ukukwera kwambiri, kuthamanga kwa kutsika kwa mtsinje kunachepetsedwa, chitsulo chochepa chokha chiyenera kuwonjezeredwa pamtengo woyenera, ndipo malonda a msika anasanduka ofooka; Zopangira phenol acetone mkulu kugwa, bisphenol A mtengo thandizo anafooka, ogula ndi ogulitsa kudikira-ndi-kuona maganizo, kutsika msika resupply osamala, magawo awiri katundu zochepa kuposa kuyembekezera, ndi kubwera kwa Mid-Yophukira Chikondwerero ndi Tsiku la National tchuthi kawiri, ena mwa otumiza sitimayo maganizo ndi zoonekeratu, weniweni wopereka phindu limodzi, kumapeto kwa mwezi, cholinga cha zokambirana msika anagwa 11500-11600 yuan/ton.

Tikuyembekezera gawo lachinayi, malinga ndi mtengo, zopangira phenol acetone akadali akuyembekezeka kuchepa, koma poganizira mtengo wapakati wa mgwirizano ndi mtengo wamtengo wapatali, zikuyembekezeka kuti malo otsika ndi ochepa, komanso mtengo wothandizira bisphenol A. ndi malire; Pankhani ya kotunga ndi kufunika, Changchun Chemical yakonzedwa kuyambira October 9, ndipo ikuyembekezeka kutha kumayambiriro kwa November, South Asia Plastics ndi Zhejiang Petrochemicals ali ndi mapulani okonza mu November, zipangizo zaumwini zili ndi mapulani okonza magalimoto kumapeto kwa October, ndi zipangizo zina. alibe mapulani omveka bwino okonzekera. Ponseponse, pali Kutayika kwa bisphenol A m'gawo lachinayi, koma nthawi yomweyo, Kumayambiriro kwa Okutobala, Jiangsu Ruiheng gawo II bisphenol A ntchito yobzala idakhazikika pang'onopang'ono, Qingdao Bay, Hengli Petrochemical, Longjiang Chemical ndi zida zina zatsopano. zipangizo akukonzekera kuyika ntchito mu kotala chachinayi, pamene mphamvu kupanga ndi linanena bungwe bisphenol A adzakhala kwambiri ntchito, ndi kuchira ofooka kwa mbali kufunika kwa msika akupitiriza kukhala kovuta kuchotsa zopinga, kutsutsana. pakati pa kupereka ndi kufuna kudzakulitsidwa. Pankhani yamalingaliro amsika, kusowa kwa chithandizo chamtengo wapatali, ntchito zoperekera komanso zofunikira ndizochepa, ndipo m'zaka zaposachedwa, msika wa bisphenol A watsika pang'onopang'ono, ndipo makampani alibe chidaliro pamsika wamtsogolo, ndipo malondawo ndi osamala. ndi kudikira ndikuwona, zomwe zimalepheretsanso kutsika kwa mtsinje wogula kumlingo wina.

Mwachidule, gawo lachinayi la msika wa bisphenol A ndizovuta kupeza zabwino, likuyembekezeka kukhala ndi kuchepa kwakukulu kwamitengo yamsika poyerekeza ndi gawo lachitatu, kupita patsogolo kwa zida zatsopano, kukwera ndi kugwa kwazinthu zopangira, kukwera ndi kugwa, kutsata kufunikira kwa kutsika kwamitengo. ndiye cholinga chachikulu cha msika.
