Inkokeli: ngo-2022,I-PVCabavelisi bemathiriyeli ekrwada ezahlukeneyo ubukhulu becala bagcina imveliso yomthwalo ophezulu, ikakhulu iqhutywa yinzuzo elungileyo yealkali.Nangona kunjalo, ngokwenzuzo ngetoni nganye yePVC, inzuzo yabavelisi bezinto ezithengiswa kumazwe angaphandle yayibomvu kakhulu unyaka wonke.Ukungena kuDisemba, kunye nezinto eziluhlaza ezinyukayo kwiidigri ezahlukeneyo zokuhla, ukunyuka kwexabiso lePVC ukothuka, ingeniso yenkampani iphuculwe.

Ngo-2022, abavelisi bePVC bezinto ezikrwada ezahlukeneyo ubukhulu becala bagcina imveliso yomthwalo ophezulu, ikakhulu iqhutywa yinzuzo elungileyo yealkali.Nangona kunjalo, ngokwenzuzo ngetoni nganye yePVC, inzuzo yabavelisi bezinto ezithengiswa kumazwe angaphandle yayibomvu kakhulu unyaka wonke.Ukungena kuDisemba, kunye nezinto eziluhlaza ezinyukayo kwiidigri ezahlukeneyo zokuhla, ukunyuka kwexabiso lePVC ukothuka, ingeniso yenkampani iphuculwe.Nangona kunjalo, uDisemba lixesha lokungabikho kwemveliso esezantsi, ngoko ke ii-odolo azilandelwa ngokwaneleyo, ii-odolo ezisezantsi zifunyanwa ngononophelo, kwaye ukuthengwa kwempahla ekrwada kulinganiselwe.Ngokusondela kweholide yoMnyhadala weNtwasahlobo, ngaba iingeniso zamashishini emveliso alandelayo aqhubeka nokuphucula?

NgoDisemba, iindleko zemithombo eyahlukeneyo yemveliso yehla ukuya kumaqondo ahlukeneyo xa kuthelekiswa naloo ngoNovemba, kodwa ixabiso lasekhaya lePVC libonise ukunyuka okuncinci ngenxa yempembelelo edibeneyo yokuvuselela umgaqo-nkqubo kunye nokuthunyelwa kwamanye amazwe kunye nezinye izinto ezifanelekileyo.Ngoko ke, ukusebenza koguqulo kwisiphelo senzuzo nako kwaphuculwa ukuya kumaqondo ahlukeneyo, kodwa ayesekwindawo embi.Phakathi kwabo, amashishini emveliso ye-PVC athenga ilahleko ye-calcium carbide inkulu kancinane.Ukususela kwi-29 kaDisemba, i-avareji yengeniso ye-grosourcing ye-calcium carbide ye-PVC yamashishini okuvelisa ngoDisemba yayingu-525.32 yuan / ton, i-48.72% ephezulu kunenzuzo enkulu ngoNovemba;Umndilili wengeniso yokubonelela nge-calcium carbide ye-PVC yamashishini okuvelisa i-497.93 yuan / ton, inyuke nge-12.20% ukusuka kwingeniso epheleleyo ngoNovemba.

Ngenxa yeendlela ezahlukeneyo zokufumana imathiriyeli ekrwada ye-ethylene, iindleko zemveliso yenkqubo ye-ethylene ziyahluka ngokubanzi phakathi kwamashishini, kwaye ukunyuka kunye nokuwa kwesiphelo senzuzo yamashishini kwahlukile.Njengoko kunokubonwa kwitshathi engentla, inqanaba lenzuzo lilonke lamashishini athenga i-vinyl chloride alilunganga, kwaye akwimo yelahleko phantse unyaka wonke, ngelixa inzuzo yamashishini abonelela nge-ethylene ngokwawo ingcono.Ukususela kwi-29 kaDisemba, i-avareji yengeniso yokuthengisa i-vinyl chloride ye-PVC yamashishini okuvelisa ngoDisemba yayiyi-46.10 yuan / ton, ingena kwimeko yokuguqula ilahleko ibe yinzuzo, kwaye inzuzo enkulu kaNovemba yanda nge-103.68%.Ingeniso eyi-avareji yengeniso yamashishini emveliso ye-vinyl ye-PVC eziboneleleyo yayiyi-989.86 yuan/toni, inyuke nge-99.16% ukusuka kwingeniso epheleleyo ngoNovemba.

NgoDisemba, ngenzuzo yamashishini emveliso ye-PVC elungiswayo ukuya kumaqondo ahlukeneyo, izinga lokuqala lilonke linyuke malunga neepesenti ze-6 xa kuthelekiswa noNovemba.Ekupheleni kukaDisemba, izinga lokuqala lahlala kuma-77.52%, ipesenti ezi-3 zamanqaku aphezulu kunexesha elifanayo kunyaka ophelileyo.

Okwangoku, kukho amashishini ambalwa olondolozo lwePVC, umthamo omtsha wemveliso, uxinzelelo lonikezelo lwasekhaya lusekho, ludityaniswa nemfuno yokukhanya kwetheminali, umdla wokuthenga awukho phezulu.Ukungena ngoJanuwari, ukunikezelwa kweemarike kusalindeleke ukuba kunyuke, kwaye imfuno ikwakwixesha eliqhelekileyo.Imiyalelo yeemveliso zamashishini ezisezantsi ziphantsi, kwaye ukuzimisela ukugcina isitokhwe kuphantsi, ngoko ke ukunikezelwa kwePVC yasekhaya kunye nemfuno iya kuqhubeka isebenza phantsi koxinzelelo.NgoJanuwari, imfuno yasekhaya ye-double-section destocking kunye nokukhululwa komthombo wokuhanjiswa kwe-V2301 kuqwalaselwa, kodwa ngokuqwalasela uxinzelelo lwangoku lweendleko zamashishini, igumbi lokunciphisa lingancitshiswa.I-East China inkqubo ye-calcium carbide Uhlobo lwe-5 indawo kwi-5900-6200 yuan / ton operation.Ngokubanzi, ngokuza kweholide yoMnyhadala weNtwasahlobo ngoJanuwari, iifektri ezisezantsi ziya kuvalwa enye emva kwenye, kwaye inzuzo yamashishini emveliso yePVC ayinakunyuka kakhulu.
