Ngo-2023, imakethi ye-anhydride yasekhaya iya kukhupha umthamo omtsha wemveliso efana ne-maleic anhydride.BDO,kodwa iya kujongana novavanyo lonyaka wokuqala omkhulu wemveliso kumxholo womjikelo omtsha wokwandiswa kwemveliso kwicala lokubonelela, xa uxinzelelo lokubonelela lunokwanda.

Umthamo omtsha wemveliso wezigidi zeetoni ze-maleic anhydride iza kwimarike kwaye icala lokubonelela liphantsi koxinzelelo olunzima
Ngo-2022, ngenxa yokucutheka kwe-real estate kunye namanye amashishini e-terminal, imfuno yangaphakathi yomlambo iya kuhla ngaphezu kokuba bekulindelwe, kwaye umthamo wokubonelela nge-anhydride ye-maleic ube yintsalela phantsi kwale mvelaphi, eya kuthi icinezele kakhulu indlela yokuthengisa. Nangona kunjalo, iqhutywa lulindelo lophuhliso lwamasimi asahlumayo asezantsi afana neeplastiki ezinokonakala kunye nezithuthi zamandla amatsha, umthamo ocetywayo we-anhydride ye-maleic yasekhaya useza kudlula iitoni ezisi-8 sezigidi kule minyaka mihlanu izayo, kwaye ishishini ke ngoko liya kuzisa umjikelo omtsha wokwandiswa komthamo ngendlela engazange ibonwe ngaphambili.
Njengonyaka wokuqala womjikelo omtsha wokwandiswa kwemveliso, ngo-2023 kuphela, i-China iya kuzisa isicwangciso esitsha samandla okuvelisa i-1.66 yezigidi zeetoni zenkqubo ye-n-butane, enokuthiwa ngunyaka wokwenene wemveliso. Oku ngokungathandabuzekiyo "kubi kakhulu" kwimarike ye-anhydride ye-maleic esele ibonelelwe ngokugqithisileyo.

Ukususela kumbono wenkqubela yemveliso, imeko yokubonelela kwisiqingatha sesibini sonyaka iya kuba nzima kakhulu. Malunga neetoni ze-300000 zomthamo wokuvelisa zicetywa ukuba zifakwe kwimveliso kwisiqingatha sokuqala se-2023, kwaye enye i-1.36 yezigidi zeetoni icwangciswe ukuba ifakwe kwimveliso kwisiqingatha sesibini se-2023; Ukusuka kwimbono yengingqi

ukuhanjiswa, uxinzelelo lonikezelo e-East China kunye nemimandla ejikelezileyo inkulu, kwaye akukho lindelo lwamandla okuvelisa amatsha eMzantsi China. I-1.65 yezigidi zeetoni zomthamo wemveliso isasazwa eShandong, eLiaoning, eHenan nakwamanye amaphondo amahlanu, apho amandla emveliso yePhondo laseLiaoning enze i-50.90% kwaye iPhondo laseShandong lithatha i-27.27%.
I-BDO kunye nezinye iimveliso ezintsha zafakwa kwimveliso kunyaka wokuqala, kwaye uphuhliso olusezantsi luye lwaba luninzi
Ukongeza kwimveliso yesiqhelo esezantsi kwe-resin engaxutywanga, indawo esezantsi ye-anhydride ye-maleic nayo iya kwamkela ukukhutshwa komthamo omtsha wemveliso efana ne-maleic anhydride BDO ngo-2023. Ngokukodwa, ukungena kwimarike yeeprojekthi ezidibeneyo kuya kwandisa kakhulu ukusetyenziswa kweemveliso ze-anhydride ze-maleic, eziza kuqala ukubumba ipateni yoshishino lwe-anhydride ye-maleic.

Nangona kunjalo, nangona kukho izicwangciso ezininzi zokubeka iimveliso ezisezantsi ze-maleic anhydride kwimveliso ngo-2023, azanelanga xa kuthelekiswa neenzame zokubeka icala lokubonelela kwimveliso. Ukonyuka kokusetyenziswa kwe-anhydride ye-maleic kunokudala kuphela imeko yobonelelo oluqinileyo eMzantsi China nakweminye imimandla, engakwaziyo ukuphelisa ngokufanelekileyo uxinzelelo lwangoku lonikezelo olugqithisileyo olujongene neshishini le-anhydride le-maleic lilonke.
Uxinzelelo olugqithisileyo lucinezela ukuthambekela kwexabiso; Iziko lamaxabiso lisenokuqhubeka nokuhla unyaka wonke
Ukukhangela phambili kwi-2023, njengoko umgaqo-nkqubo wamva nje wokuzinzisa imarike uqhubeka ukhula, imarike yendawo yokuhlala inokuba nethuba lokuphuma phantsi kunye nokuzinza, kunye nemfuno yeemveliso ezisezantsi ze-anhydride ye-maleic ezifana ne-resin unsaturated kunye nepeyinti kulindeleke ukuba ibone ukuhla. Ukongeza, umthamo wemveliso ye-BDO kunye nezinye iimveliso ziye zafakwa ekusebenzeni ngokulandelelana, ukusetyenziswa kwasekhaya kwe-anhydride ye-maleic ngo-2023 kuya kunyuka kakhulu xa kuthelekiswa naloo 2022. Nangona kunjalo, ukunyuka kwemfuno kungenakukuphelisa ngokupheleleyo ukwanda kokunikezelwa kwe-anhydride ye-maleic. Kulindeleke ukuba uxinzelelo lonikezelo lwe-surplus ye-anhydride ye-maleic luza kuqhubeka ngo-2023, kwaye umgangatho wexabiso uya kugxila kutshintsho oluthile kwicala lokubonelela.
