Ka 2023, katoloso e kholo ea indasteri ea PC ea China e felile, mme indasteri e kene potolohong ea ho cheka matla a tlhahiso a teng. Ka lebaka la nako e bohareng ea katoloso ea lisebelisoa tse tala tse holimo, phaello ea PC e tlase e eketsehile haholo, phaello ea indasteri ea PC e ntlafetse haholo, 'me sekhahla sa ts'ebeliso le tlhahiso ea matla a tlhahiso ea lapeng le tsona li eketsehile haholo.

Ka 2023, tlhahiso ea PC ea lapeng e bonts'itse mokhoa oa khoeli le khoeli o nyolohang, o phahame haholo ho feta nalane ea nako e ts'oanang. Ho ea ka lipalo-palo, ho tloha ka January ho ea ho May 2023, kakaretso ea tlhahiso ea PC Chaena e ne e le lithane tse ka bang limilione tse 1.05, keketseho e fetang 50% ha e bapisoa le nako e tšoanang selemong se fetileng, 'me tekanyo ea tšebeliso ea matla e fihlile ho 68,27%. Har'a bona, tlhahiso e tloaelehileng ho tloha ka Hlakubele ho isa Mots'eanong e feta lithane tse 200000, e leng habeli sekhahla sa selemo le selemo ka 2021.
1. Katoloso e bohareng ea matla a lehae e felile, 'me matla a macha a tlhahiso lilemong tse hlano tse tlang a batla a lekanyelitsoe.
Ho tloha ka 2018, matla a tlhahiso ea PC ea China a eketsehile ka potlako. Ho tloha bofelong ba 2022, kakaretso ea tlhahiso ea PC ea lapeng e fihlile ho lithane tse limilione tse 3.2 / selemo, keketseho ea 266% ha e bapisoa le bofelong ba 2017, ka sekhahla sa kholo ea selemo le selemo sa 30%. Ka 2023, Chaena e tla eketsa bokhoni ba tlhahiso ka lithane tse 160000 tsa Wanhua Chemical le ho qala bocha bokhoni ba tlhahiso ka lithane tse 70000 ka selemo Gansu, Hubei. Ho tloha ka 2024 ho isa ho 2027, tlhahiso e ncha ea PC ea China e lebelletsoe ho feta feela lithane tse limilione tse 1.3, ka sekhahla sa kholo e tlase haholo ho feta nakong e fetileng. Ka hona, lilemong tse hlano tse tlang, ho cheka matla a tlhahiso a teng, ho ntlafatsa boleng ba sehlahisoa butle-butle, tlhahiso e fapaneng, ho nkela thepa e tsoang kantle ho naha, le ho eketsa thepa e tsoang kantle ho naha e tla fetoha molumo oa mantlha oa indasteri ea PC ea China.
2. Lisebelisoa tse tala li kene nakong ea katoloso e bohareng, e lebisang ho fokotseha ho hoholo ha litšenyehelo tsa ketane ea indasteri le ho theoha butle-butle ha phaello.

Ho ea ka liphetoho tsa thepa e tala ea bisphenol A le matla a mabeli a maholo a tlhahiso ea tlaase lilemong tse hlano tse fetileng, phapang ea bokhoni ba tlhahiso ea 2022 e fihlile boemong bo tlaase ka ho fetisisa lilemong tse hlano, ho lithane tse limilione tse 1.93 ka selemo. Ka 2022, matla a tlhahiso ea bisphenol A, PC, le epoxy resin e nang le litekanyetso tsa kholo ea selemo le selemo tsa 76.6%, 13.07%, le 16.56%, ka ho latellana, e ne e le tse tlaase ka ho fetisisa ketane ea indasteri. Ka lebaka la keketseho e kholo le phaello ea bisphenol A, phaello ea indasteri ea PC e eketsehile haholo ka 2023, e fihletse boemo ba eona bo holimo lilemong tsa morao tjena.

Ho tsoa liphetohong tsa phaello ea PC le bisphenol A lilemong tse tharo tse fetileng, phaello ea indasteri ho tloha 2021 ho isa 2022 e tsepamisitsoe haholo pheletsong e holimo. Le hoja PC e boetse e na le phaello e kholo ea mekhahlelo, moeli o tlase haholo ho feta oa lihlahisoa tse tala; Ka December 2022, boemo bo ile ba fetoha ka molao mme PC e ile ea fetola ka molao tahlehelo ho ba phaello, ea feta bisphenol A haholo ka lekhetlo la pele (1402 yuan le -125 yuan ka ho latellana). Ka 2023, phaello ea indasteri ea PC e ile ea tsoela pele ho feta ea bisphenol A. Ho tloha ka January ho ea ho May, phaello ea kakaretso ea bobeli e ne e le 1100 yuan/ton le -243 yuan/ton, ka ho latellana. Leha ho le joalo, selemong sena, phenol ketone ea thepa e ka holimo e ne e boetse e le boemong ba tahlehelo e kholo, 'me PC e ile ea fetola tahlehelo ka molao.
Lilemong tse hlano tse tlang, matla a tlhahiso ea li-ketone tsa phenolic, bisphenol A, le li-resin tsa epoxy li tla tsoela pele ho atoloha haholo, 'me PC e lebeletsoe hore e tsoele pele ho ba le phaello e le e' ngoe ea lihlahisoa tse seng kae tsa ketane ea indasteri.
3. Bophahamo ba thepa e tsoang kantle ho naha bo fokotsehile haholo, ha thepa e romelloang kantle ho naha e entse likhahla tse itseng.

Ka 2023, theko ea kantle ho naha ea PC ea lapeng e theohile haholo. Ho tloha ka Pherekhong ho isa ho Mmesa, kakaretso ea thepa ea kantle ho naha ea PC ea lapeng e ne e le lithane tse 358400, ka kakaretso ea thomello ea lithane tse 126600 le theko ea kantle ho naha ea lithane tse 231800, phokotseho ea lithane tse 161200 kapa 41% ha e bapisoa le nako e tšoanang selemong se fetileng. Ka lebaka la ho tlosoa ka mafolofolo / ho se nang letho ha thepa e tsoang linaheng tse ling le ho hōla ha thepa e tsoang mose ho maoatle, ho nkeloa sebaka ha thepa ea malapeng har'a basebelisi ba tlaase ho ea holimo ho eketsehile haholo, e leng ho khothalelitseng haholo kholo ea tlhahiso ea PC ea lehae selemong sena.
Ka Phuptjane, ka lebaka la tlhokomelo e reriloeng ea likhoebo tse peli tse tšehelitsoeng ka lichelete kantle ho naha, tlhahiso ea PC ea lehae e kanna ea fokotseha ha e bapisoa le Mots'eanong; Karolong ea bobeli ea selemo, lisebelisoa tse tala tse holimo li ile tsa tsoela pele ho angoa ke ho atolosoa ha matla, ho etsa hore ho be thata ho ntlafatsa phaello, ha PC e tlaase e ntse e tsoela pele ho etsa phaello. Khahlanong le maemo ana, phaello e tsitsitseng ea indasteri ea PC e lebelletsoe ho tsoela pele. Ntle le lifeme tse kholo tsa PC tse ntseng li thehile merero ea tlhokomelo ho tloha ka August ho ea ho September, e tla ama tlhahiso ea khoeli le khoeli, tšebeliso ea matla a malapeng le tlhahiso e tla lula e le boemong bo batlang bo le holimo ka kakaretso bakeng sa nako e setseng. Ka hona, ho lebeletsoe hore tlhahiso ea PC ea malapeng karolong ea bobeli ea selemo e tla tsoela pele ho hōla ha e bapisoa le halofo ea pele.
