Mu Januwale 2023, chifukwa cha "chiyembekezo champhamvu" komanso kukonza ndi kuchedwa kwa zida zingapo zapakhomo, malowa amatha, ngakhale kufunikira kuli kocheperako, koma mtengo wamsika ndi wamphamvu. Pambuyo pa Chikondwerero cha Spring, mapeto a malowo sanasinthe, ndipo msika wapakhomo wa styrene ndi wofooka komanso wosasunthika. Pambuyo pa tchuthi cha Meyi Day, msika wapakhomo wapakhomo udafowokanso pambuyo povuta, ndipo unagwera pansi pa "8" chikwi chapakati pa Meyi, ndikupitilira kutsika. East China styrene msika kuyambira chiyambi cha chaka 8400 yuan/tani, mpaka panopa 7360 yuan/tani, kuchepa kwa 12.38%.

Kuyambira kuchiyambi kwa 2023, kufalikira kwa styrene ndi zopangira zamtengo wapatali za benzene kunawonetsa "zoyamba zotambasula kenako zopapatiza", kusiyana kwamitengo pakati pa styrene ndi benzene yoyera kunali 1349 yuan/ton, kuwonjezeka kwa 17.20% nthawi yomweyi chaka chatha, ndipo phindu lapakati pa zipangizo zosaphatikizana za styrene zinali pafupifupi -28 yuan / tani, kuwonjezeka kwa synchronous kwa 92,86% panthawi yomweyi chaka chatha. Ngakhale mtengo wa styrene ndi benzene koyera mu 2023 udatsika mofananiza poyerekeza ndi nthawi yomweyi chaka chatha, koma gawo lachaka dongosolo loyika ma styrene, kukonza kwakunja kumachitika pafupipafupi, msika udawoneka "wopereka ndi kufunafuna zolimba" chitsanzo, ndi mbali yopangira benzene yoyera imakhala ndi "phindu lalikulu", kusiyana kwamitengo pakati pa ziwirizi kumakhala pamtunda. Pansi pakupanga kwakukulu kwa styrene, kutsutsana pakati pa kupezeka ndi kufunikira kukukulirakulirabe, ndipo phindu la zida zosagwirizana ndi styrene zikupitiliza kukonzanso, kutha kwazinthu zopangira sikungapatse thandizo lamphamvu la styrene.

Kusagwirizana pakati pa kupezeka ndi kufunikira kukukulirakulira: styrene ikukula mwachangu, ndipo kufunikira kuli kochepa.

M'kanthawi kochepa, styrene mu gawo lachitatu akadali mu kuchuluka kwa kuchuluka kwa mphamvu ndi zotulutsa, ndipo deta ikuwonetsa kuti kuwonjezereka kwatsopano kwa chipangizo cham'mbali choperekera kudzakhala kwakukulu kuposa kuwonjezereka kwatsopano kwa chipangizo cha mbali yofunikira. Pakali pano, malingaliro odziwika bwino a nkhani, styrene ndi kutsika mu theka lachiwiri la chaka, ngakhale atakhudzidwa ndi kusintha kwa kupanga ndi malonda a malonda, zida zambiri zidzachedwa kuchedwa, zomwe zimapereka kusintha kwakukulu kwa kuwonjezeka kwa styrene ndi zofuna, koma ndi zida zatsopano zomwe zikuyikidwa mukupanga, kuwonjezereka kwa styrene m'gawo lachitatu kumayembekezeredwa, ndipo kupezeka kwa msika ndi kufunikira kwa nyengo yotentha kwambiri mu July ndi August ndizofooka. Msikawu udayambanso kuwonjezereka koyambirira ndikukonza njira yoperekera ndi kufunidwa chida chatsopanocho chikalowa mumsika, chopangidwa kuti chipewe kutentha kwambiri nyengo isanakwane, ndipo msika udagwa. Mu Ogasiti kapena anayamba kunyamula, "golide naini siliva khumi" kupanga chikhalidwe pachimake nyengo ikupitiriza kupereka msika ndi malo okwera mtengo, chonsecho, gawo lachitatu la msika m'nyumba styrene kapena "ofooka pambuyo chizolowezi amphamvu", styrene msika. ikadali yozikidwa pa mtengo ndi kupereka ndi kufunikira kwa mizere iwiri ya zotsatira.
