Ngo-2025, imboni ye-styrene ibonise umkhuba "wokwehla kokuqala bese kuba ukubuyiselwa" phakathi kokuxhumana phakathi kokukhululwa kwamandla agxilile kanye nokwehluka kwesidingo sesakhiwo. Njengoba ingcindezi ohlangothini lokuhlinzeka yehla kancane, izimpawu zokwehla kwemakethe zacaca ngokwengeziwe. Kodwa-ke, ukungqubuzana kwesakhiwo phakathi kwempahla ephezulu kanye nokwehluka kwesidingo kwahlala kungaxazululwa, okuvimbela indawo yokubuyela emuva kwentengo.
Ukushaqeka komthamo ohlangothini lokuhlinzeka kwakuyisici esiyinhloko esinzima emakethe engxenyeni yokuqala yonyaka. Ngo-2025, umthamo omusha wokukhiqiza i-styrene yasekhaya waqala ukusabalala ngendlela egxilile, kanti umthamo omusha wonyaka owengeziwe udlula amathani ayizigidi ezimbili. Amaphrojekthi amakhulu okuhlanganisa ukucwenga nokuhlanganisa amakhemikhali njengeLiaoning Baolai kanye neZhejiang Petrochemical anikele ekukhuleni okukhulu, okuqhuba ukukhula komthamo wonyaka nonyaka okungu-18%. Ukukhululwa komthamo ogxilile, kanye nokuntuleka kwesidingo kwendabuko kwikota yokuqala, kwandise ukungalingani kwemakethe nokufunwa. Amanani e-styrene aqhubeka nokwehla kusuka ku-8,200 yuan ngethani ekuqaleni konyaka, afinyelela ezingeni eliphansi lonyaka lama-yuan angu-6,800 ngethani ekupheleni kuka-Okthoba, okumele ukwehla ngo-17% kusukela ekuqaleni konyaka.
Ngemuva maphakathi noNovemba, imakethe yaqala ukwehla kancane kancane, amanani enyuka afinyelela cishe ku-7,200 yuan ngethani, ukwanda okungaba ngu-6%, okubonisa ukuvela kokuqala kwezimpawu zokwehla. Ukwehla kwabangelwa yizici ezimbili eziyinhloko. Okokuqala, uhlangothi lokuhlinzeka lwancipha: amasethi amathathu ezitshalo ezinomthamo waminyaka yonke wamathani ayizigidi eziyi-1.2 eShandong, eJiangsu nakwezinye izifunda amisa ukusebenza okwesikhashana ngenxa yokugcinwa kwemishini noma ukulahlekelwa yinzuzo, okwehlisa izinga lokusebenza lamasonto onke lisuka ku-85% laya ku-78%. Okwesibili, uhlangothi lwezindleko lunikeze ukwesekwa: oluqhutshwa ukwehla kwamanani kawoyela emhlabeni jikelele kanye nokwehla kwezitoko zechweba, intengo ye-benzene yokudla yanda ngo-5.2%, inyusa izindleko zokukhiqiza ze-styrene. Noma kunjalo, izitoko eziphezulu zahlala ziyisithiyo esiyinhloko. Ekupheleni kukaNovemba, izitoko ze-styrene emachwebeni ase-East China zafinyelela kumathani ayi-164,200, okuphakeme ngo-23% kunesikhathi esifanayo ngonyaka odlule. Izinsuku zokushintshana kwezitoko zahlala ezinsukwini eziyi-12, zidlula kakhulu ibanga elifanele lezinsuku eziyi-8, zinciphisa ukwanda okwengeziwe kwentengo.
Iphethini yesidingo ehlukanisiwe ikhulise ubunzima bemakethe, okuholele "ekusebenzeni okubili" okucacile kuzo zonke izigaba eziyinhloko ezingezansi. Imboni ye-ABS (Acrylonitrile-Butadiene-Styrene) ivele njengeyona nto evelele kakhulu: izuza ekuthunyelweni kwezimoto ezintsha zamandla kanye nemishini yasekhaya ehlakaniphile ekhulayo, isidingo sayo sonyaka sanda ngo-27.5% unyaka nonyaka. Abakhiqizi abakhulu be-ABS basekhaya bagcine izinga lokusebenza elingaphezu kuka-90%, okwenza isidingo sokuthengwa esiqhubekayo se-styrene. Ngokuphambene kakhulu, imboni ye-PS (Polystyrene) kanye ne-EPS (Expandable Polystyrene) zibhekane nesidingo esinciphile esiphansi, esidonswa ubuthakathaka obude emakethe yezindlu. I-EPS isetshenziswa kakhulu ezintweni zokuvikela udonga lwangaphandle; ukwehla okungu-15% unyaka nonyaka kokuqala kokwakhiwa kwezindlu ezintsha kuholele ekutheni abakhiqizi be-EPS basebenze ngaphansi kuka-50%. Phakathi naleso sikhathi, abakhiqizi be-PS babone izinga labo lokusebenza lihamba cishe ngo-60%, ngaphansi kakhulu kwezinga lesikhathi esifanayo ngonyaka odlule, ngenxa yokukhula okuhamba kancane kokuthunyelwa kwamanye amazwe kwezimboni zokukhanya ezifana nokupakisha namathoyizi.
Njengamanje, imakethe ye-styrene isesigabeni esilinganiselwe esibonakala “ngokuncipha kokuhlinzekwa okuhlinzeka ngomehluko wephansi kanye nesidingo okunciphisa amandla okukhuphuka”. Nakuba izici zokwehla ziye zavela, umfutho wokubuyela emuva usalinde ukususwa kwempahla okusebenzayo kanye nokubuyiselwa kwesidingo okugcwele. Esikhathini esifushane, esivinjelwe yimikhawulo yokuthutha yasebusika emikhiqizweni yamakhemikhali kanye nokuqala kabusha kwezinye izitshalo zokulungisa, imakethe kulindeleke ukuthi ishintshe ngandlela thile. Esikhathini esiphakathi kuya kweside, kufanele kuqashelwe umphumela wokukhulisa izinqubomgomo zezindlu ezikhululekile esidingweni se-PS kanye ne-EPS, kanye nokwandiswa kwesidingo se-ABS emkhakheni wokukhiqiza osezingeni eliphezulu. Lezi zici zizonquma ngokuhlanganyela ukuphakama kokubuya kwentengo ye-styrene.
