Okwangoku, zombini i-PVC ngokwayo kunye ne-calcium carbide enyukayo ziphantsi kobonelelo oluqinileyo.Ukukhangela phambili kwi-2022 kunye ne-2023, ngenxa ye-PVC yoshishino lweepropati zokusetyenziswa kwamandla aphezulu kunye neengxaki zonyango lwe-chlorine, kulindeleke ukuba kungabikho kufakelo oluninzi oluya kufakwa kwimveliso.Umzi-mveliso wePVC unokungena kumjikelo owomeleleyo kangangoko iminyaka emi-3-4.
Imarike ye-calcium carbide iyaqhubeka nokuphucula
I-Calcium carbide yi-industry ene-energy ephezulu, kunye neenkcukacha ze-calcium carbide furnaces ngokubanzi ziyi-12500KVA, i-27500KVA, i-30000KVA, kunye ne-40000KVA.Iziko le-calcium carbide ngaphantsi kwe-30000KVA ngamashishini athintelwe ngurhulumente.Umgaqo-nkqubo wamva nje okhutshwe yi-Inner Mongolia yile: i-arc furnaces engaphantsi kwe-30000KVA, ngokomgaqo, zonke ziphuma ngaphambi kokuphela kwe-2022;abaqeqeshiweyo banokuphumeza ukutshintshwa kokunciphisa umthamo kwi-1.25: 1.Ngokwezibalo zombhali, imboni yelizwe ye-calcium carbide inomthamo wokuvelisa we-2.985 yezigidi zeetoni ngaphantsi kwe-30,000 KVA, i-8.64%.Iifarnaces ezingaphantsi kwe-30,000KVA kwi-Inner Mongolia zibandakanya amandla okuvelisa iitoni ezingama-800,000, ezibalelwa kwi-6.75% yomthamo opheleleyo wemveliso kwi-Inner Mongolia.
Okwangoku, inzuzo ye-calcium carbide iye yaphakama kwiindawo eziphakamileyo zembali, kwaye ukunikezelwa kwe-calcium carbide kunqongophala.Izinga lokusebenzisa i-calcium carbide furnaces kufuneka lihlale liphezulu, kodwa ngenxa yeempembelelo zomgaqo-nkqubo, izinga lokusebenza alinyukanga kodwa linqabile.Imboni yePVC esezantsi nayo inezinga eliphezulu lokusebenza ngenxa yeenzuzo zayo ezizuzisayo, kwaye kukho imfuno enamandla ye-calcium carbide.Ukujonga phambili, isicwangciso sokuqalisa ukuveliswa kwe-calcium carbide sinokuhlehliswa ngenxa "yokungathathi hlangothi kwekhabhoni".Ngokuqinisekileyo isityalo se-Shuangxin se-525,000-ton kulindeleke ukuba sisetyenziswe kwisiqingatha sesibini salo nyaka.Umbhali ukholelwa ukuba kuya kubakho ukutshintshwa komthamo wePVC kwixesha elizayo kwaye akuyi kuzisa ukunyuka kokubonelela okutsha.Kulindeleke ukuba imboni ye-calcium carbide ibe kumjikelezo woshishino kwiminyaka embalwa ezayo, kwaye ixabiso le-PVC liya kuhlala liphezulu.
Ubonelelo olutsha lwehlabathi lwePVC luphantsi
I-PVC lishishini elisebenzisa amandla amaninzi, kwaye lahlulwe kwizixhobo zenkqubo ye-ethylene yonxweme kunye nezixhobo zenkqubo ye-calcium carbide e-China.Incopho yemveliso ye-PVC yayikwi-2013-2014, kwaye izinga lokukhula kwamandla okuvelisa laliphezulu, likhokelela ekugqithiseni kwi-2014-2015, ilahleko yoshishino, kwaye izinga lokusebenza lilonke liye lahla kwi-60%.Okwangoku, amandla okuvelisa i-PVC ahambile ukusuka kumjikelo we-surplus ukuya kumjikelo weshishini, kwaye izinga lokusebenza phezulu lisondele kwi-90% yembali ephezulu.
Kuqikelelwa ukuba imveliso encinci ye-PVC yasekhaya iya kufakwa kwimveliso ngo-2021, kwaye izinga lokukhula lonyaka lonyaka liya kuba malunga ne-5% kuphela, kwaye kunzima ukunciphisa ukunikezelwa okuqinileyo.Ngenxa yemfuno emileyo ngexesha loMnyhadala weNtwasahlobo, iPVC ngoku iqokelelana ngamaxesha athile onyaka, kwaye inqanaba le-inventri likwinqanaba elingathathi hlangothi unyaka nonyaka.Kulindeleke ukuba emva kokuba imfuno iphinde iqale ukuchithwa kwisiqingatha sokuqala sonyaka, i-inventory ye-PVC iya kuhlala iphantsi ixesha elide kwisiqingatha sesibini sonyaka.
Ukususela kwi-2021, i-Inner Mongolia ayisayi kuphinda ivume iiprojekthi zamandla amatsha afana ne-coke (i-blue charcoal), i-calcium carbide, kunye ne-polyvinyl chloride (PVC).Ukuba ulwakhiwo luyimfuneko ngokwenene, umthamo wemveliso kunye nokutshintshwa kokunciphisa ukusetyenziswa kwamandla kufuneka kuphunyezwe kummandla.Kulindeleke ukuba akukho ndlela entsha ye-calcium carbide umthamo wokuvelisa we-PVC uya kufakwa kwimveliso ngaphandle komthamo ocwangcisiweyo wokuvelisa.
Kwelinye icala, izinga lokukhula komthamo wemveliso wePVC phesheya liye lehla ukusukela ngo-2015, ngesantya esiphakathi sokukhula esingaphantsi kwe-2%.Ngo-2020, i-disk yangaphandle iya kungena kwi-tight supply balance situation.Ifakwe phezulu kwimpembelelo yenkanyamba yase-US kwikota yesine ye-2020 kunye namaza abandayo ngoJanuwari 2021, amaxabiso e-PVC aphesheya anyukele kwimbali ephezulu.Xa kuthelekiswa namaxabiso ePVC aphesheya kweelwandle, iPVC yasekhaya ayicingelwanga kangako, ngenzuzo yokuthumela ngaphandle kwe-1,500 yuan/ton.Iinkampani zasekhaya zaqala ukufumana inani elikhulu lee-odolo zokuthumela ngaphandle ukusuka ngoNovemba ka-2020, kwaye i-PVC itshintshile ukusuka kwiindidi ezifuna ukuthunyelwa kumazwe angaphandle ukuya kwiindidi zokuthumela ngaphandle.Kulindeleke ukuba kubekho ii-odolo zokuthunyelwa kwempahla kumazwe angaphandle kwikota yokuqala ka-2021, nto leyo eye yandisa imeko yobonelelo lwePVC yasekhaya.
Kule meko, ixabiso lePVC lilula ukunyuka kodwa kunzima ukuwa.Ukuchasana okuphambili okwangoku kukuchasana phakathi kwePVC yexabiso eliphezulu kunye neenzuzo ezisezantsi.Iimveliso ezisezantsi ngokubanzi zinokunyuka okucothayo kwexabiso.Ukuba i-PVC yexabiso eliphezulu ayikwazi ukuhanjiswa ngokutyibilikayo ukuya ezantsi, ngokuqinisekileyo iya kuchaphazela ukuqala kwezantsi kunye nemiyalelo.Ukuba iimveliso ezisezantsi zinokunyusa amaxabiso ngokuqhelekileyo, amaxabiso ePVC angaqhubeka nokunyuka.
