mokhoa oa calcium carbide PVC, mokhoa oa ethylene PVC litšenyehelo, litšenyehelo PVC, Baetsi ba PVC, Litšenyehelo tsa PVC tsa ts'ebetso ea vinyl,
Lilemong tsa morao tjena, theko ea PVC e fetoha haholo, 'me phaello ea likhoebo tse nang le mekhoa e fapaneng le eona e fapane haholo.Likhoebo tse tšehetsang thepa e tala li na le phaello, athe likhoebo tse hlokang ho bokella thepa e tala li tobane le tahlehelo.
E le ts'ebetso ea tlhahiso ea PVC e jang lithane tse 1.4 tsa calcium carbide ka thane, phetoho ealitšenyehelo PVCMokhoa oa calcium carbide o angoa haholo ke calcium carbide.Ho tloha ka Mphalane 2020, theko e ntseng e phahama ea calcium carbide e lebisitse ho phahama halitšenyehelo PVC.Haholo-holo ka mor'a 2021, tlas'a semelo sa tlhahlobo ea tšebeliso ea motlakase, calcium carbide, e le indasteri e sebelisoang haholo ea matla, e thibetsoe haholo.Litsenyehelo tsa likhoebo tsa PVC li ntse li nyoloha ka keketseho.Ka Mphalane 2021, litšenyehelo tsa likhoebo tse ling tsa China Bochabela li feta 15000 yuan/ton.Qetellong ea 2022, theko ea calcium carbide e bolokiloe ho 3900-4550 yuan/ton, ka theko e phahameng e hlahang bohareng ba Hlakubele le theko e tlase ho elella bofelong ba Hlakola le Mmesa.Ka hona, litšenyehelo tsa likhoebo tsa PVC le tsona lia lumellana.
Litšenyehelo tsa PVC tsa ts'ebetso ea vinylliphetoho li angoa ke theko ea ethylene le vinyl chloride.Litsenyehelo tsa likhoebo tsa PVC tse sebelisang mokhoa oa ethylene li eketseha butle-butle ho tloha bofelong ba April 2020, ho qala ka phetoho ea VCM, boemo bo phahameng ka ho fetisisa bo hlaha ho elella bofelong ba Mphalane 2021, ho feta 14,600 yuan/ton.Ka January 2022, phepelo ea vinyl chloride e ile ea eketseha, 'me litšenyehelo tsa likhoebo tsa tlhahiso ea PVC ts'ebetsong ea ethylene li fokotsehile;Ka February tlhokeho e tlase ea noka ea vinyl chloride e ntlafetse, theko e ile ea phahama;Ka March, phepelo ea VCM Asia e ne e le thata, 'me litšenyehelo tse phahameng ka ho fetisisa e ne e le 9750 yuan/ton qetellong ea March.
Karolong ea pele ea 2022, boemo ba phaello ea calcium carbide PVC bo ne bo lokile, haholo-holo bo rua molemo ka theko e tlase ea calcium carbide e tala.Ka January, phaello e kholo ea PVC e hlahisoang ke merafo ea linaheng tse ling Shandong e ne e le 33.6 yuan / tonne, keketseho ea 1182.6 yuan / tonne, le keketseho ea 6.6 yuan / tonne selemo le selemo;Qetellong ea February, phaello ea PVC e entsoeng ka ntle ho tlhahiso ea electrolyte e ile ea eketseha ka 165.5 yuan / tonne ho ea ho 199.1 yuan / ton.Qetellong ea March, phaello ea PVC e hlahisoang ke tlhahiso ea ka ntle ea lejoe la electrolytic e ne e le 774 yuan / ton.
Ho latela accounting e tsoang ho VCM, kotareng ea pele ea 2022, phaello ea phaello ea PVC e entsoeng ka mokhoa oa ethylene e tlase ho feta ea lik'hamphani tsa mokhoa oa calcium carbide.Ka January, litšenyehelo tsaBaetsi ba PVCe ile ea theoha, theko ea 'maraka e ile ea nyoloha hanyane,' me phaello ea likhoebo e ile ea eketseha.Ho kena ka February, angoa ke theko e phahameng ea vinyl chloride e tala, ethylene mokhoa oa theko e eketseha, ka nako e tšoanang bohareng le ho elella bofelong ba February qala ho fokolisa mokhoa oa 'maraka, mokhoa oa ethylene theko e lokolohang, mokhoa oa vinyl oa tlhahiso ea kantle ea tahlehelo e eketsehileng.Ka March, ha theko ea PVC e phahama 'me theko ea VCM e theoha, phaello ea likhoebo tsa PVC e sebelisang mokhoa oa ethylene (PVC) e ntlafetse.Empa likhoebo tsa lapeng tsa vinyl PVC hangata ke lisebelisoa tse kopaneng, 'me sebaka sa phaello se seholo ho feta likhoebo tsa PVC.
