I, ukubuyekezwa kwemakethe
I-PVC(6402, 10.00, 0.16%) inkontileka eyinhloko ngo-December 30 ivalwe ngo-6263 yuan/ton, ngenyanga inyuke ngo-312 yuan/ton (5.24%).
Uma sibheka emuva kuwo wonke uZibandlela, engxenyeni yokuqala yenyanga, izinkontileka eziyinhloko zibonise ukuthambekela okukhuphukayo ngenxa yokuhoxiswa kwenqubomgomo yobhubhane kanye nokuxegiswa kwenqubomgomo yezindlu.Engxenyeni yesibili yenyanga, ngokuphinda kube nomthelela wobhubhane kanye nesidingo esivilaphayo ekupheleni konyaka, izinga lokuhlinzekwa kanye nesidingo lehlulekile ukunikeza impendulo eyakhayo, futhi kancane kancane imakethe yangena ekuhlanganisweni kokushaqeka.Ngasekupheleni konyaka, umphumela weholide uphinde wavela, obonisa ukuthambekela kokukhuphuka okuphelele.
II, ukuhlaziya indawo
Inqubo yokukhiqiza ye-PVC inezinhlobo ezimbili: indlela ye-calcium carbide nendlela ye-ethylene, indlela ye-ethylene yekhwalithi ye-PVC ehlanzekile futhi iyunifomu, intengo iphakeme kancane kunendlela ye-calcium carbide ye-PVC.Izinhlobonhlobo zokulethwa kwekusasa le-PVC ezweni lethu yi-SG5 grade 1 ehambisana nezinga lezwe.Ayikho imingcele ecacile yokuthi umkhiqizo wokulethwa wenziwa yinqubo ye-calcium carbide noma inqubo ye-vinyl.
Kusukela ngomhla ka-30 Disemba 2022, intengo nokusabalala kwe-PVC kuboniswa ngezansi:
Ngalolo suku, intengo yendawo emaphakathi ye-vinyl PVC e-China yayingu-6,313 yuan/ton, ikhuphuke ngo-165 yuan/ton uma kuqhathaniswa nokuphela kwenyanga edlule.
Ngalo lolo suku, intengo yendawo emaphakathi ye-calcium carbide PVC ingu-6,138 yuan/ton, uma kuqhathaniswa nokuphela kwenyanga edlule, ikhuphuke ngo-198 yuan/ton.
Umehluko wamanani phakathi kwendlela ye-ethylene nendlela ye-calcium carbide ngalolo suku wawungu-175 yuan/ton, uma kuqhathaniswa nokuphela kwenyanga edlule, ikhuphuke ngama-yuan angama-33/ton, umehluko wentengo usesezingeni eliphansi lomlando.
Kusukela ngomhla ka-30 Disemba 2022, ukusabalala kwentengo yendawo yesikhathi esizayo ye-PVC kungu--66 yuan/ton, 3 yuan/ton ngaphansi kosuku lwangaphambilini, okusezingeni eliphansi emlandweni.
III.Ukuhlaziywa kokuhlinzeka
Sekuyisikhathi eside, imakethe ye-PVC yaseShayina iyiphethini yokuthuthukiswa ehambisana nezinhlobo ezimbili zemigqa yobuchwepheshe, indlela ye-calcium carbide kanye nendlela ye-ethylene, kodwa ngenxa yezimpawu "zamalahle acebile, uwoyela ompofu kanye negesi elincane" ezweni lakithi, Indlela ye-calcium carbide I-PVC isibe ubuchwepheshe obuhamba phambili ezweni lethu, kodwa emakethe yamazwe ngamazwe, imikhiqizo ye-PVC evamile yenziwa ngendlela ye-ethylene, futhi i-ethylene ikhiqizwa ngokuqhekeka kwamandla okufana nowoyela negesi.Ngakho intengo ye-PVC nezintengo zikawoyela zamazwe ngamazwe zibonisa ukuhlobana okuqinile.
Indlela yenqubo ye-vinyl PVC imi kanje: uwoyela ongahluziwe - naphtha - ethylene - dichloroethane (EDC) - vinyl chloride (VCM) - polyvinyl chloride (PVC)
Inqubo ye-calcium carbide isetshenziswa kakhulu emabhizinisini okukhiqiza i-chlor-alkali yamaShayina ukuze kukhiqizwe i-PVC, kanti ukukhishwa kwe-PVC ngenqubo ye-calcium carbide kubala cishe amaphesenti angama-80 omkhiqizo usuwonke eChina.
Inqubo yokukhiqiza i-calcium carbide polyvinyl chloride yile: Amalahle - i-calcium carbide - i-acetylene - i-vinyl chloride (VCM) - i-polyvinyl chloride (PVC) indlela yokunciphisa ugesi iyindlela evamile yokukhiqiza imboni ye-calcium carbide okwamanje, le ndlela ithatha i-coke (2798 , 29.50, 1.07%) kanye ne-lime njengezinto zokusetshenziswa, ngokusho kwesilinganiso esinqunyiwe sokuxutshwa kwesithando somlilo esivaliwe se-calcium carbide, i-Calcium carbide ikhiqizwa ngokushisa kagesi ku-2000-2200 degrees.Njengoba le ndlela idinga ukusebenzisa inani elikhulu lamandla kagesi, izindleko zikagesi zenza ingxenye enkulu yezindleko eziphelele zamabhizinisi okukhiqiza i-polyvinyl chloride esebenzisa indlela ye-calcium carbide.
Ukufingqa, intengo yesikhathi esizayo ye-PVC ithintwa amalahle ashisayo (0, -921.00, -100.00%) (intengo kagesi), amanani e-coke ne-calcium carbide ngesikhathi esifanayo, okubonisa ukuhlobana okuphezulu.
NgoJanuwari 03, 2023, inani lekusasa lamalahle lamandla e-China lingu-921 yuan/ton, uma kuqhathaniswa nosuku lwangaphambilini, alukho ushintsho;Intengo yokulethwa kwe-coke ingu-2,610 yuan/ton, uma kuqhathaniswa nosuku lwangaphambilini, yehle ngo-95 yuan/ton.
Kusukela ngomhla ka-30 Disemba 2022, inani lentengo elimaphakathi le-calcium carbide ezimbonini ezijwayelekile ze-calcium carbide eNyakatho-ntshonalanga ye-China ngu-3,910 yuan/ton, elingenalo ushintsho uma liqhathaniswa nosuku lwangaphambilini.Intengo yendawo ye-calcium carbide ezweni ingu-4,101 yuan/ton, uma kuqhathaniswa nosuku lwangaphambilini, alukho ushintsho.
Lapho amabhizinisi e-chlor-alkali ekhiqiza i-chlorine ewuketshezi, aphinde athole i-caustic soda, umkhiqizo ohlobene.Eminyakeni yamuva, intengo ye-caustic soda kanye ne-liquid chlorine yenza umphumela we-seesaw, okungukuthi, lapho intengo ye-caustic soda iphezulu, intengo ye-chlorine ewuketshezi iphansi, futhi ngokuphambene nalokho, okwenza inzuzo ye-chlor-alkali. amabhizinisi agcina esezingeni elifanele.I-Liquid chlorine kunzima ukuyigcina futhi ithuthwe amabanga amade, ngakho-ke abakhiqizi bavame ukuhlanganisa i-PVC futhi basebenzise izitokwe ze-chlorine eziwuketshezi ezingaphezulu.
Umfula we-caustic soda ikakhulukazi uhlanganisa i-alumina, ukwenza amaphepha, ukuphrinta nokudaya kanye nezimboni zamakhemikhali.Ukufudumala komfula we-caustic soda kuzothuthukisa ukwanda kokukhiqizwa kwe-caustic soda yamabhizinisi e-chlor-alkali, kanye nomkhiqizo we-chlorine owuketshezi ohlobene uzokwenziwa i-PVC, ngaleyo ndlela kukhuphule kancane ukunikezwa kwemakethe kwe-PVC, okuzocindezela intengo yemakethe PVC ngezinga elithile.Ngokuvamile, izintengo ze-PVC zivame ukuhlala ziphezulu lapho amanani e-caustic soda ephansi.
Kusukela ngomhla ka-30 Disemba 2022, intengo yendawo ye-ionic membrane caustic soda ingu-1,344 yuan/ton, uma kuqhathaniswa nosuku lwangaphambilini, alukho ushintsho, futhi intengo yamanje isendaweni ephezulu yomlando.
Njengamanje, isidingo esikhulu se-caustic soda e-China sivela kusixhumanisi sokukhiqiza i-alumina, ngakho intengo ye-caustic soda kanye nentengo ye-alumina ibonisa ukuhlobana okuphezulu.
I-aluminium ye-electrolytic yasekhaya isetshenziswa kabanzi ezimbonini ezithengisa izindlu, izimoto kanye nezimboni zamandla kagesi.Ukutholwa kwalezi zimboni ezingezansi kuzonyusa isidingo semikhiqizo ye-aluminium, ezodluliselwa enhla nomfula, kukhuphule intengo ye-caustic soda futhi kuthinte ngokungaqondile inkambiso yentengo yekusasa le-PVC.
Kusukela ngomhla ka-30 Disemba 2022, intengo yendawo ye-alumina yasekhaya ingu-2,965 yuan/ton, alukho ushintsho uma luqhathaniswa nosuku lwangaphambilini, futhi intengo yamanje isendaweni eyisilinganiso yomlando.
