Sanadkii 2023, ballaarinta ururudu waxay soo gabagabeysay warshadaha PC ee Shiinaha ayaa dhamaatay, warshaduna waxay soo gashay wareegga ay ku dheehan tahay awoodda wax soo saarka ee jira. Sababo la xiriira muddada ballaarinta dhexe ee agabka ceyriinka ee sare, faa iidada ugu hooseysa ee PC-ga hoose ayaa si weyn u kordhay, macaashka warshadaha PC si weyn ayey u soo hagaagtay, iyo heerka ka-faa'iideysiga iyo wax soo saarka awoodda wax soo saarka gudaha ayaa sidoo kale si weyn u kordhay.

Sanadkii 2023, soosaarka PC-ga gudaha ayaa muujisay isbeddel bil kasta kor u kaca, aad uga sarreyso heerka taariikhiga ah ee isla muddadaas. Marka loo eego tirakoobka, laga soo bilaabo bishii Janaayo ilaa May 2023, wadarta soosaarka kombuyutarka ee Shiinaha ayaa ahaa 1.05 milyan oo tan, marka la barbar dhigo isla muddadaas sanadkii la soo dhaafay, iyo celceliska heerka isticmaalka awooda ayaa gaartay 68.2.27%. Waxaa ka mid ah, celcelis ahaan wax soo saarka Maarso si ay u dhaafi karto 200000 tan, oo labanlaab ah heerka celceliska celceliska sanadlaha ah ee 2021.
1. Fidinta dhexe ee awoodda guryaha asal ahaan waa la soo gabagabeeyey, iyo awoodda wax soo saarka ee cusub shanta sano ee soo socota ayaa xadidan.
Ilaa iyo sanadka 2018, awoodda waxsoosaarka PC ee Shiinaha ayaa si dhaqso leh u ballaariyay. Dhamaadkii 2022, wadarta awoodda wax soo saarka PC ee PC-ga ee guriga ayaa gaartay 3.2 milyan oo tan ah / sanadka, oo ah koror 266% marka loo eego dhammaadka sannadka 2017, oo leh heerka koritaanka sanadlaha ah ee xarunta 30%. Sannadkii 2023, Shiinaha ayaa kordhin doona awoodda wax soo saarka oo ay gaarayaan 160000 tan oo ah awoodda wax soo saarka kiimikada iyo dib-u-bilaabida wax soo saarka oo dhan 70000 tan oo ku yaal Gansu, Hubei. Laga soo bilaabo 2024 ilaa 2027, awoodda wax soo saarka cusub ee Shiinaha ayaa la filayaa inuu ka bato 1.3 milyan oo tan, oo leh heerka koritaanka si weyn hoos u dhacay. Sidaa darteed, shanta sano ee soo socota, dheefshiidka awoodda wax soo saarka ee jira, si isdaba joog ah u hagaajinta wax soo saarka sheyga, wax soo saarka kaladuwan, wax soo saarka, iyo dhoofinta sii kordhaya waxay noqon doontaa codka ugu weyn ee warshadaha PC-ga Shiinaha.
2. Alaabada ceyriinka ah waxay galeen muddo ah ballaarin xarun dhexe, taasoo horseedaysa hoos u dhac weyn oo ku dhaca qarashka silsiladda warshadaha iyo hoos u dhac tartiib ah oo ku yimaadda macaashka.

Marka loo eego isbedelada ku dhaca sheyga ceyriinka ah ee Bispherenol a iyo labada awoodood ee ugu hooseysa ee hoos udhaca ah shantii sano ee la soo dhaafay, farqiga u dhexeeya wax soo saarka sare iyo heerka hoose ee 2022 ayaa gaadhay heerka ugu hooseeya muddo shan sano ah, 1.93 milyan tan sanadkii. Sanadkii 2022, awoodda wax soo saarka ee Bisphenol A, PC, iyo Epoxy Rein oo leh heerarka kobaca sanadka ee sanad-sano-sano-sano ah, 13.07%, iyo 16.56%, waxay ahaayeen kuwa ugu hooseeya silsiladda warshadaha. Thanks to fidinta weyn iyo faa iidada ee Bisphenol A, faa'iidada warshadaha PC-ga ayaa si weyn kor ugu kacay 2023, iyadoo la gaarey heerka ugu wanaagsan sannadihii ugu dambeeyay.

Isbedelka faa'iidada ee PC iyo Bisphenol a Saddexdii sano ee la soo dhaafay, oo ah kan qarsoon ee warshadaha laga soo bilaabo 2021 illaa 2022 waxaa inta badan lagu saarayaa dhamaadka kore. In kasta oo PC sidoo kale ay leedahay faa'iidooyin wajiga oo weyn, xaddiga xad-dhaafka ah wuu ka hooseeyaa kan alaabta ceeriin ah; Bishii Disembar 2022, xaaladda ayaa si rasmi ah u noqotay oo PC si rasmi ah u rogay khasaaraha faa'iidooyinka, ka-hortagga Bisenol waa markii ugu horreysay (1402 Yuan iyo -125 Yuan. Sanadkii 2023, faa'iidada warshadaha PC-ga ayaa sii waday inay ka badato in Bisphenol A. Laga soo bilaabo heerarka heerka guud ee guud ee labada ay ahaayeen 1100 yuan / ton iyo -243 yuan / ton, siday u kala horreeyaan. Si kastaba ha noqotee, sannadkan, dhamaadka kore ee sheyga ceyriinka ah ee phenone ketone ketone ketone ketone ketone ayaa sidoo kale khasaare weyn ku jiray dowlad weyn, PC-ka ayaa si rasmi ah u rogay khasaaraha.
Shanta sano ee soo socota, awoodda soosaarka ee phonenes ketones, bisphenol a, iyo ephoxy ress-ka ayaa sii wadi doona ballaarinta, PC-ga ayaa la filayaa inuu u noqdo mid faa iido u leh sida mid ka mid ah waxyaabaha kooban ee silsiladda warshadaha.
3. Mugga soo dejinta ayaa si weyn hoos ugu dhacay, iyadoo dhoofinta ay sameysay xoogaa horumar ah.

Sanadkii 2023, soo dejinta saafiga ah ee PC-ga gudaha ayaa si weyn u burburay. Laga bilaabo Janaayo ilaa Abriil, wadarta mugga soo dejinta ee PC-ga gudaha wuxuu ahaa 358400 tan, oo ah mugga isu-dejinta ee 126600 tan iyo 11800 tan, oo hoos u dhac ah 161200 tan ama 41% marka loo eego isla muddadaas sanadkii la soo dhaafay. Thanks to ka bixitaanka firfircoon / ka bixitaanka meelaha la dhoofiyo iyo koritaanka dhoofinta dibada, beddelka qalabka guryaha ee dadka isticmaala ee aad u kordhay, oo sidoo kale si weyn u dalacsiiyay koritaanka soosaarka PC-ga gudaha sanadkan.
Bisha Juun, sababtuna tahay dayactirka qorsheysan ee laba shirkadood oo ajnabi ah oo ay maalgaliso, soosaarka PC-ga gudaha ayaa laga yaabaa inuu hoos u dhigo marka loo eego May; Qeybtii labaad ee sannadka, agabkii ceyriinka ee kor u kacay ayaa sii waday inay saameeyaan ballaarinta tamarta, taasoo adkeyneysa hagaajinta macaashka, halka PC hoos u riixeysa PC-ga hoostiisa uu sii waday inuu macaash sameeyo. Ka soo horjeedka dib-u-soo noqoshada, faa'iidooyinka joogtada ah ee warshadaha PC-ga ayaa la filayaa inay sii socdaan. Marka laga reebo warshadaha waaweyn ee PC-ga ee wali aasaasay qorshayaasha dayactirka laga bilaabo Agoosto ilaa Sebtember, kaas oo saameyn ku yeelan doona soosaarka billaha ah, adeegsiga awoodda awoodda iyo waxsoosaarka ayaa ku sii jiri doona heer sare oo heersare ah waqtiga harsan. Sidaa darteed, waxaa la filayaa in soosaarka kombuyutarka ee PC-ga ee qeybtii labaad ee sanadka uu sii wadi doono kobcinta marka la barbar dhigo qeybtii hore.
