Sannadkii 2023, dhammaan warshadaha silsiladda warshadaha styryl-ABS-PS-EPS ee Shiinaha ayaa galay marxalad wareeg ah oo sahaydu xad dhaaf tahay, marka laga eego dhinaca awoodda cusub, styrene iyo ABS ayaa safka hore kaga jira kobaca sannad-sannadeedka, siday u kala horreeyaan 21% iyo 41%, laakiin heerka kobaca dhinaca baahida ayaa gaabis ah, taasoo keentay hoos u dhac joogto ah oo ku yimaada faa'iidada warshadaha kala duwan ee silsiladda warshadaha. Gaar ahaan, faa'iidada ABS iyo PS ayaa si weyn hoos ugu dhacday sannad-sannadeedka, iyadoo qiyaastii 90%. Awoodda warshadaha silsiladda warshadaha ay sii wadi karto ballaarinta isbeddelka, laakiin dhinaca baahida way adag tahay in la helo meel koboc cusub, dhammaan warshadaha waxay la kulmi doonaan xaalad xun oo ah iswaafaq la'aanta saadka iyo baahida, hoos u dhaca kobaca macro iyo warshadaha iyo arrimo kale oo xun, cadaadiska hawlgalka warshadaha ayaa si weyn u kordhay.

Sannadkii 2023, wax soo saarka styrene iyo isticmaalka styrene ayaa sii waday inuu koro iyadoo saddexda wax soo saar ee dhexe ee hoose ay hoos u dhaceen.

Laga bilaabo 2019 ilaa 2023, heerka kobaca isku-dhafka ah ee wax soo saarka styrene ee Shiinaha wuxuu ahaa 16.05%, taasoo muujinaysa koror joogto ah sannadba sannadka ka dambeeya, laga bilaabo 2020-2022, wax soo saarku wuxuu ku jiray xaalad koror sare ah, iyadoo celcelis ahaan koror sannadle ah oo ah qiyaastii 1.63 milyan oo tan. Sannadkii 2023, iyadoo wareeg cusub oo ah xilliga qaraxyada awoodda wax soo saarka, wax soo saarka styrene ayaa mar kale ku fiday in ka badan 2 milyan oo tan sannadkii. Laga bilaabo 2021, xaaladda awoodda xad-dhaafka ah ee styrene ee gudaha ayaa si tartiib tartiib ah u soo ifbaxday, iyadoo la soo bandhigay awood cusub, isticmaalka awoodda ayaa si dheeraad ah loo xakameeyay. Sannadkii 2023, iyadoo ay ugu wacan tahay wax soo saarka dhexe ee warshadaha hoose, waxaa jira koror weyn oo ku yimid baahida, taas oo xasilinaysa bilowga rakibidda cusub.

Laga bilaabo 2019 ilaa 2023, isticmaalka styrene-ka Shiinaha ayaa muujiyay isbeddel sii kordhaya sannadba sannadka ka dambeeya, iyadoo heerka kobaca sanadlaha ah uu ahaa 7.89% shantii sano ee la soo dhaafay, isticmaalka styrene-kuna wuxuu gaaray 16.03 milyan oo tan sannadkii 2023, taasoo ah koror dhan 13.66% marka la barbar dhigo 2022. Laga bilaabo 2019 ilaa 2021, sababtoo ah faa'iidada wanaagsan ee styrene-ka, isbeddelka qiimaha styrene saameyn weyn kuma yeelan isticmaalka styrene. Sannadka 2022, faa'iidada guud ee silsiladda warshadaha styrene-ka ayaa kor u kici doonta, badeecadaha styrene-ka iyo kuwa hoose-na si tartiib tartiib ah ayay u geli doonaan khasaarooyin, taasoo keentay in isticmaalka styrene-ku uu yaraado. Sannadka 2023, xitaa haddii faa'iidada wax soo saarka ee hoose aysan weli wanaagsanayn, laakiin cadaadis tartan ah oo ka dhashay wax soo saarka xooggan, warshadda hoose waxay ku jirtaa xaalad ku adkaysiga wax soo saarka, isla markaana, baahida terminalku waxay sidoo kale leedahay waxqabad ka wanaagsan, asal ahaan waxay dheefshiidaysaa kororka wax soo saarka guud ee hoose, ugu dambayntiina waxay horseeddaa koror cad oo ku yimaada baahida styrene inta lagu jiro sannadka.

Sannadka 2024, wax soo saarka hoose ee styrene waa "dheeraad", cadaadiska silsiladda warshadahana hoos ayaa loo dhigayaa!

Sannadka 2024, saadka iyo baahida styrene ayaa la filayaa inay sii wadaan inay muujiyaan kobac. Sida laga soo xigtay qiyaasaha xogta Longzhong, marka laga eego qorshaha maalgashiga cusub ee qalabka styrene sanadka 2024, hal qalab oo cusub oo styrene ah qeybtii labaad ee sannadkii hore, taas oo ah, qalab 600,000 tan/sanadka ah oo ah Shandong Jingbo Petrochemical oo markii hore la filayay in la hawlgeliyo laga bilaabo Maarso ilaa Abriil, iyo qalab 450,000 tan/sanadka ah oo ah Shenghong Refining and Chemical kaas oo la qorsheeyay in la hawlgeliyo qaybta labaad ee sannadka, wadarta guud waa 1.05 milyan oo tan/sanadkii. Marka la barbardhigo 2023, awoodda wax soo saarka sanadlaha ah ayaa la filayaa inay hoos u dhacdo 71.62%, kororka styrene-na waa xaddidan yahay sanadka oo dhan. Hoosta, maalgashiga la filayo ee hadda jira, EPS waxaa si ku meel gaar ah loo filayaa inay yeelato 1 milyan oo tan/sanadkii qorshe cusub oo awood qalab ah ka hor maalgashiga, PS waxay leedahay 1.25 milyan oo tan/sanadkii qorshe cusub oo awood qalab ah ka hor maalgashiga, ABS waxay leedahay 2 milyan oo tan/sanadkii qorshe cusub oo awood qalab ah ka hor maalgashiga.

Soo koobid: Sannadkii 2023, wax soo saarka hoose ee styrene ayaa soo muuqda, baahidana si weyn ayay u korodhay, taas oo xasilinaysa bilowga qalabka cusub ee styrene. Inkasta oo awoodda wax soo saarka hoose ee styrene ay korodhay sannadkii, laakiin la'aanta baahida terminal-ka ee la socota ayaa horseeday hoos u dhac ku yimid isticmaalka awoodda wax soo saarka, laakiin horumarinta suuqa, waxaa la filayaa in awoodda wax soo saarka cusub ee styrene sannadka 2024 ay ka hoosayso kororka ugu weyn ee hoos u dhaca, xaaladda sahayda dabacsan iyo baahida styrene sannadka 2024-kana la yareyn doono.
