2. Zuza futhi uqalise -thatha i-PVC njengesibonelo
Isibalo esingezansi sikhetha ikusasa le-PVC nokusebenza kwenzuzo kusukela ngo-2016 kuze kube manje.Phakathi kwazo, inzuzo ikhethe ummeleli u-Shandong ngaphandle-kwe-Shandong ngaphandle kwamatshe obuciko kanye nenzuzo ehlanganisiwe.Ngenxa yobuhle bezinsiza zamalahle, izindleko ziphansi kunalezo zaseMpumalanga China.Kulula ukumela inzuzo encane yemboni.Njengamanje, amandla kagesi asekhaya alinganiselwa ku-80 %, i-ethylene amandla oMsunguli alinganiselwa ku-20 %, kanti umthamo ophelele wokukhiqiza we-chlorine cishe u-70%.Njengoba inzuzo yamabhizinisi ahlanganisiwe e-chlorine -alkali iphezulu kakhulu kunenzuzo yenkampani, i-East China isetshenziselwa ukusebenzisa i-East China emazweni angaphandle.Inzuzo yebhizinisi le-PVC lamatshe kagesi izinga eliphansi kakhulu embonini.Isibonelo, inkampani ye-PVC inenzuzo, khona-ke imboni inenzuzo iyonke.Uma amabhizinisi e-PVC ahlanganisiwe e-East China enokulahlekelwa yinzuzo, ukukhiqizwa okuvamile kwamabhizinisi kungase kuthinteke.
Uma sibheka kusukela ngo-2016 kuya ku-2023, lapho inzuzo yezinkampani zikagesi ngaphandle kwaseMpumalanga China ifinyelela cishe ku-1,000, ngokuyisisekelo yayiphelezelwa phezulu emakethe ehleliwe, njengangoNovemba 2016, Septhemba 2017, no-Okthoba 2021. Lapho ukuhlanganiswa kwengonyama elahlekile yakhiwe, ngokuyisisekelo ihambisana nephansi elihleliwe, elifana noJanuwari 2016, Januwari 2022, noNovemba 2022. Uma sibheka imodeli yesizini yemboni, i-PVC inesondlo kabili ngonyaka entwasahlobo nasekwindla, ngokulandelana kusukela ngo-Ephreli noJuni futhi Julayi-Septhemba.Izigaba ezintathu eziphezulu ziseduze nenkathi yesondlo.Ukungalingani kwezigaba zokuhlinzeka nokufunwa kulethe ukukhuphuka kwamanani.Lapho inzuzo yezinkampani ikhula, imboni yakhuphuka ngokushesha ngangokunokwenzeka.Ngemuva kokuthi ukunikezwa kunyukile kanye nokugcwaliswa kabusha kwesizindalwazi kwehla isivinini, imakethe yaqala.Lapho ukulahlekelwa kokuhlanganiswa kwe-chlorine -alkali, imboni yehlile ngesigaba.Nakuba kungekho ukuhlolwa okuvamile kulesi sigaba, kusezingeni eliphansi ngesikhathi esifanayo.Ngamanye amazwi, ukwakhiwa kwenzuzo ukuthatha uhlobo "V".Lapho ukulahlekelwa, ukwakhiwa "kuguquliwe", futhi inzuzo ihlobene kahle
Ngenxa yokuthi uchungechunge lwemboni ye-PVC luhlanganiswe kakhulu, ezinye izesekeli kufanele zicatshangelwe ngokugcwele lapho kuxoxwa ngenzuzo ye-PVC.Phakathi kwazo, umthelela omkhulu yimikhiqizo ekhuphuka nomfula kanye ne-alkali yemikhiqizo ehambisana nayo.Njengamanje, amandla okukhiqiza we-Corporal Method makhulu kakhulu, ngakho-ke izindleko zamatshe kagesi kanye ne-PVC zihlobene kakhulu.Ngokuvamile, amanani e-PVC akhuphuke ngentengo yamatshe kagesi.U-2021 unyaka okhethekile.Ithintwa kokubili ukusetshenziswa kwamandla.Ukunikezwa okuphansi kwamatshe kagesi kuqinile, futhi intengo yamatshe kagesi ikhuphukile.Ezinkampanini ze-PVC zikagesi ezizithwalayo, umdlandla wokuqalisa uphezulu uma kuqhathaniswa.Kulesi sigaba, inzuzo itholakala ikakhulukazi yifekthri ye-electron (imboni yamatshe kagesi ekwazi ukuzigcina ingakwazi ukwengeza inzuzo ye-PVC ngenzuzo yetshe likagesi), ukuze kubonakale ukuthi kuyabonakala ukuthi iyabonakala. ukuthi kungabonakala Ngisho noma intengo ye-PVC iqhubekile nokuphula intengo ephezulu ngo-2021, inzuzo yezinkampani ze-PVC zezinkampani ze-PVC ngokuvamile ilahlekelwa yimali.Le ngxenye yebhizinisi inciphise ukukhiqizwa noma ukulungiswa.Ukwengeza Isikhathi esifanayo senkathi efanayo siphansi.
Amashidi ePvc angaphandle epulasitiki
Intengo ye-alkali ye-alkali nayo inomthelela omkhulu ekuziphatheni kokwakhiwa kwezinkampani ze-PVC.Ngokuvamile, i-1 ton PVC ihambisana namathani angu-0.7-0.8 we-alkalinity.Inzuzo phakathi kwabo ithintene.Ukuwa, inkampani ye-PVC isivele iqalile ukuthuthukisa ukulahlekelwa, kodwa ngalesi sikhathi umsebenzi wemboni awuzange uthinteke kakhulu.Kuze kube nguJulayi, intengo ye-alkaline pyrine iwile, okubangela ukulahlekelwa kwenzuzo yenkampani ehlanganisiwe ye-chlorine ne-alkali.Imakethe ye-PVC izophinde ibuyele emuva.NgoNovemba 2022, i-alkali ye-alkali yehliswe kancane, futhi inzuzo ephelele ye-chlorine -alkali yayilahlekelwa imali.NgoMashi, intengo ye-alkaline eyosiwe yehla kakhulu, futhi ukulahlekelwa kwe-chlorine -alkali edidiyelwe kwanda kakhulu.Njengoba sekuzongena inkathi yesondlo, kuyabonakala ukuthi isikhathi sokuqala salo nyaka sisengaphambili kuneminyaka edlule.
Ngokuvamile, kumabhizinisi amakhemikhali, umfula okhuphukayo uzolungiswa ngokuya ngenzuzo yesikhathi sangempela, futhi ukunikezwa okuhlukaniswa ngezigaba kanye nesidingo kuzolungiswa ngokuthinta ukunikezwa.Ngesikhathi esifanayo, ukuhlaziywa kwenzuzo kufanele kuhlanganiswe nenqubo yezimboni.Uma sithatha i-PVC njengesibonelo, kufanele ihlukaniswe ibe yinhlanganisela futhi ingahlanganisiwe.Ngaphezu kwalokho, kuyadingeka ukuhlanganisa inzuzo yetshe kanye ne-alkali.Ukwengeza, inkampani eqoqa ugesi ithole inzuzo ethile njengemali engaphezulu yemboni, futhi ukulahlekelwa kwamabhizinisi ahlanganisiwe kungene embonini.Ngesikhathi esifanayo, kufanele kucatshangelwe ngokuhambisana nezinye izici.
Fingqa
Inzuzo izothinta imodeli yokuziphatha yebhizinisi.Njengemboni yamakhemikhali, izinkampani ezikhuphuka nomfula zigxile kakhulu.Esikhathini esifushane, izinguquko enzuzweni esikhathini esifushane zizothinta ukwakhiwa komfula okhuphukayo.Inzuzo idluliselwa ekupheleni kwentengo ngokuthinta ukunikezwa.Uma ubheka emuva emakethe yomlando ngomqondo ojwayelekile othi "valuation+driver", ukulinganisa kuvame ukuba yizimo ezanele, futhi umthelela wangempela emakethe ulele kumshayeli.I-rebound ibuyela kokujwayelekile (isibonelo, izindleko zokulungiswa okubandayo ziphezulu, ingilazi ngeke ibanda lapho ingilazi ilahlekile, futhi uhlangothi lokuhlinzeka ngeke luncishiswe ngokushesha).Ngesikhathi esifanayo, imboni ayinanzuzo.Inani lokulinganisa ukuhlanganisa izinto eziyisisekelo zomkhiqizo.Isibonelo, ngaphansi kokulinganisa okuphezulu kwezinhlobonhlobo ezifana ne-PVC, umfula ophansi uzonciphisa ukuthenga izimpahla, futhi i-alkali efana nengilazi engezansi iyadingeka nje.Izinto zokusetshenziswa azikwazi ukumisa ukunikezwa.Isikhathi eside).Ngaphezu kwalokho, lapho wahlulela ukulinganisa, udinga ukunaka inqubo yomkhiqizo.Isibonelo, ku-PVC, umthamo wokukhiqiza weqoqo likagesi wangaphandle unomthamo omncane wokukhiqiza.Uhlangothi lokuhlinzeka lubangele umthelela omkhulu, futhi imboni yokulahlekelwa inzuzo yamabhizinisi ahlanganisiwe e-chlorine -alkali izoshintsha.Lapho ukhetha isu, ukulinganisa kungadluliselwa kokunye kwezinqumo.Kudingeka kakhulu ukubona amandla omshayeli.Uma sithatha i-PVC njengesibonelo, ukulinganiswa kwamanje kwamabhizinisi amaningi akubanga phezulu ngaphansi kokulahlekelwa ukulahlekelwa.Isidingo, kulindeleke ukuthi kuncishiswe ukukhiqizwa ngo-Ephreli kanye nokwanda kwesidingo.Ngokombono wenzuzo nokulahlekelwa kunombono wenzuzo nokulahlekelwa, inani elincane lingafaniswa ngentengo yamanje.Gxila esimweni sezindawo kamuva.okulinganiselwe.
