Ngo-2023, imakethe yasekhaya ye-maleic anhydride izokwethula ukukhululwa komthamo womkhiqizo omusha njenge-maleic anhydride.BDO,kodwa izophinde ibhekane novivinyo lonyaka wokuqala omkhulu wokukhiqiza kumongo womjikelezo omusha wokunwetshwa kokukhiqiza ohlangothini lokuhlinzeka, lapho ingcindezi yokuhlinzeka ingase ikhule.

Umthamo omusha wokukhiqiza wamathani ayizigidi ze-maleic anhydride iza emakethe futhi uhlangothi lokuhlinzeka lungaphansi kwengcindezi enkulu
Ngo-2022, ngenxa yokuncipha kwezindawo ezithengiswayo nezinye izimboni zokugcina, isidingo sasekhaya esisezansi nomfula sizokwehla ngaphezu kwalokho obekulindelwe, futhi umthamo wokuhlinzekwa kwe-maleic anhydride ube yinsada ngaphansi kwalesi sizinda, okuzocindezela kakhulu ukuthambekela kwemakethe. Kodwa-ke, ngenxa yokulindela ukuthuthukiswa kwezinkambu ezisafufusa ezansi nomfula njengamapulasitiki awonakele kanye nezimoto zamandla amasha, umthamo ohlongozwayo we-maleic anhydride usazodlula amathani ayizigidi eziyisi-8 kule minyaka emihlanu ezayo, ngakho-ke imboni izongenisa umzuliswano omusha. ukunwetshwa komthamo okungakaze kubonwe ngaphambili.
Njengonyaka wokuqala womzuliswano omusha wokwandisa ukukhiqizwa, ngo-2023 kuphela, i-China izokwethula uhlelo olusha lwamandla okukhiqiza amathani ayizigidi eziyi-1.66 wenqubo ye-n-butane, okungashiwo ukuthi unyaka wangempela wokukhiqiza. Lokhu akungabazeki ukuthi "kubi kakhulu" emakethe ye-anhydride ye-maleic esivele inikezwe ngokweqile.

Ngokombono wenqubekelaphambili yokukhiqiza, isimo sokuhlinzeka ngengxenye yesibili yonyaka sizoba sibi kakhulu. Cishe amathani angu-300000 omthamo wokukhiqiza kuhlelwe ukuthi afakwe ekukhiqizeni engxenyeni yokuqala ka-2023, kanti amanye amathani ayizigidi ezingu-1.36 ahlelwe ukuthi afakwe ekukhiqizeni engxenyeni yesibili ye-2023; Ngokombono wesifunda

ukusatshalaliswa, ingcindezi yokuhlinzeka eMpumalanga yeChina nasezindaweni ezizungezile inkulu kakhulu, futhi akukho okulindelekile kwamandla amasha okukhiqiza eNingizimu yeChina. Amathani ayizigidi ezingu-1.65 amandla okukhiqiza asatshalaliswa ikakhulukazi eShandong, eLiaoning, eHenan nakwezinye izifundazwe ezinhlanu, lapho amandla okukhiqiza eSifundazwe saseLiaoning ebalelwa ku-50.90% kanye nawesiFundazwe saseShandong enze u-27.27%.
I-BDO neminye imikhiqizo emisha yafakwa ekukhiqizweni onyakeni wokuqala, futhi ukuthuthukiswa komfula kwaba nokuhlukahluka kakhulu
Ngaphezu komkhiqizo wendabuko ophansi komfula unsaturated resin, inkambu engezansi yomfula we-maleic anhydride izokwamukela futhi ukukhululwa komthamo womkhiqizo omusha njenge-maleic anhydride BDO ngo-2023. Ikakhulukazi, ukungena emakethe kwamaphrojekthi ahlanganisiwe kuzokwandisa kakhulu ukusetshenziswa kwe-maleic. imikhiqizo ye-anhydride, ezoqala ukubumba iphethini yemboni ye-maleic anhydride.

Kodwa-ke, nakuba zikhona nezinhlelo eziningi zokubeka imikhiqizo engaphansi kwe-maleic anhydride ekukhiqizweni ngo-2023, azikanele uma ziqhathaniswa nemizamo yokufaka uhlangothi lokuhlinzeka ekukhiqizeni. Ukwanda kokuzisebenzisa ngokwakho kwe-anhydride yamaleic kungase kudale kuphela isimo esiqinile sokuhlinzekwa kwezinsiza eNingizimu yeShayina nakwezinye izifunda, ezingakwazi ukudambisa ngempumelelo ingcindezi yamanje yokunikezwa ngokweqile okubhekene nemboni ye-anhydride yonkana.
Ingcindezi eyeqile icindezela umkhuba wamanani; isikhungo samanani singase siqhubeke nokwehla unyaka wonke
Sibheke ngabomvu ku-2023, njengoba inqubomgomo yakamuva yokusimamisa imakethe iqhubeka nokukhula, imakethe yezindlu nezindlu ingase ibe nethuba lokuphuma phansi futhi izinze, futhi isidingo semikhiqizo ephansi yomfula i-anhydride yamaleic efana ne-resin unsaturated nopende kulindeleke ukuthi ibonakale. phansi phezulu. Ngaphezu kwalokho, amandla okukhiqiza e-BDO neminye imikhiqizo asetshenziswe ngokulandelana, ukusetshenziswa kwasekhaya kwe-maleic anhydride ngo-2023 kuzokhuphuka kakhulu uma kuqhathaniswa nalokho ngo-2022. Kodwa-ke, ukwanda kwesidingo kungase kungaqedi ngokuphelele ukwanda i-anhydride ye-maleic. Kulindeleke ukuthi ingcindezi yokutholakala kwensalela ye-maleic anhydride iqhubeke ngo-2023, futhi inkambiso yamanani izogxila ezinguqukweni ezithile ohlangothini lokuhlinzeka.
