1. Matla a tlhahiso a ntlafatsoa ka ho eketsehileng, 'me matla a nts'etsopele ea mashala ho ethylene glycol a maholo.
Ho ea ka Analysis e tebileng ea China Ethylene Glycol Industry Development and Future Investment Research Report (2022-2029) e lokollotsoeng ke Guanyan Report Network, lilemong tsa morao tjena, indasteri ea lefats'e ea ethylene glycol e tsoetse pele ka potlako, ka matla a tlhahiso ea ethylene glycol le tlhahiso e ntseng e eketseha selemo. ka selemo.Ka 2021, tlhahiso ea lefats'e ea ethylene glycol e tla eketseha ka 19.4% selemo le selemo, 'me tlhahiso e tla eketseha ka 7.5% selemo le selemo.Tlas'a semelo sena, bokhoni ba tlhahiso le tlhahiso ea indasteri ea China ea ethylene glycol le eona e ntse e eketseha selemo le selemo.
Mabapi le matla a tlhahiso, ha naha e ela hloko indasteri ea ethylene glycol haholoanyane, tataiso e nepahetseng le maano a tšehetsang joalo ka Foromo ea Khothatso le Ts'ebeliso ea Theknoloji le Lihlahisoa ho Indasteri ea Petrochemical le Lik'hemik'hale ka 2021, Maikutlo a Tataiso mabapi le Kholiso. Ntlafatso ea Boleng bo Phahameng ba Indasteri ea Petroli le Lik'hemik'hale nakong ea "Leano la Lilemo tse Leshome le Metso e Mehlano" le Maikutlo a Tataiso mabapi le Ntlafatso ea Boleng bo Phahameng ba Indasteri ea Lik'hemik'hale tsa Lik'hemik'hale ka 2022 li ntse li tsoela pele ho fanoa, 'me tikoloho ea leano la indasteri e ntse e tsoela pele ho ba ntle, ethylene glycol ea Chaena. matla a tlhahiso a eketseha selemo le selemo.Ho latela data, tlhahiso ea China ea ethylene glycol e tla eketseha ho tloha ho lithane tse limilione tse 8,32 ho isa ho lithane tse limilione tse 21.45 ho tloha 2017 ho ea ho 2021, ka karolelano ea selemo le selemo ea kholo ea kholo ea hoo e ka bang 31%.
Mabapi le tekanyo ea tšebeliso ea matla, tekanyo ea kakaretso ea tšebeliso ea matla a ethylene glycol Chaena e tlaase hona joale, e neng e ka ba 68.63% ka 2017;E tla nyolohela ho 73.42% ka 2019. Leha ho le joalo, ho tloha 2020 ho ea ho 2021, ka lebaka la tšusumetso ea ho itšehla thajana ha seoa lapeng, tlhokomelo ea sesebelisoa sa ethylene glycol, tekanyo ea matla le theko e phahameng ea mashala, thepa ea malapeng ea ethylene glycol e tlaase, 'me ka kakaretso. indasteri e qala ho theoha haholo, ho fella ka hore sekhahla sa tšebeliso ea matla a ethylene glycol Chaena se theohele ho 60.06% le 55.01% ka ho latellana lilemong tse peli tse fetileng.
Mabapi le tlhahiso, ka ho atolosoa ha 'maraka oa ethylene glycol le keketseho e akaretsang ea tlhokahalo e tlaase, tlhahiso e boetse e bontša mokhoa oa ho hōla selemo le selemo.Ho tloha 2017 ho isa 2021, tlhahiso ea China ea ethylene glycol e eketsehile ho tloha ho lithane tse limilione tse 5.71 ho isa ho lithane tse limilione tse 11.8, 'me sekhahla sa kholo ea eona se boetse se bonts'a mokhoa o holimo lilemong tse peli tse fetileng, ka lebaka la kholo e kholo ea tlhahiso ea eona.Ka 2021, sekhahla sa kholo ea ethylene glycol ea China se ne se ka ba 21.65% selemo le selemo, liperesente tse 2.63 li phahame ho feta tsa 2020.
Ho tloha phetohong ea matla a tlhahiso ea ethylene glycol ea Chaena, ho ka bonoa hore matla a tlhahiso ea ethylene glycol ea Chaena a ntlafalitsoe le ho feta lilemong tse hlano tsa morao tjena, 'me indasteri e boemong ba kholo le nts'etsopele.
