I-anhydride ye-maleiciyikhemikhali ebalulekile ephakathi nendawo esetshenziswa ekukhiqizeni imikhiqizo ehlukahlukene efana nezinsalela ze-polyester ezingagcwalisiwe, okokunamathela, okunamathelisa kanye nezithasiselo zokuthambisa. Imakethe yomhlaba wonke ye-anhydride ye-maleic ibilokhu ikhula njalo eminyakeni yamuva, futhi lo mkhuba kulindeleke ukuthi uqhubeke kuze kube ngu-2024. Kule bhulogi, sizocubungula izindaba zakamuva zemakethe kanye nezitayela ezithinta i-maleic anhydride.
Isidingo se-anhydride ye-maleic siqhutshwa izici ezimbalwa ezibalulekile. Ukukhula kwemboni yezokwakha emhlabeni wonke kunomthelela omkhulu, njengoba i-maleic anhydride isetshenziswa kakhulu ekukhiqizeni izinto zokwakha ezifana ne-fiberglass, amapayipi, namathangi. Ngaphezu kwalokho, ukwanda kwesidingo sezinto ezingasindi nezihlala isikhathi eside embonini yezimoto kanye ne-aerospace nakho kuholele ekwenyukeni kokusetshenziswa kwe-maleic anhydride.
Enye yezinto ezibalulekile emakethe ye-maleic anhydride umkhuba okhulayo obheke emikhiqizweni esimeme kanye ne-eco-friendly. I-anhydride ye-maleic isetshenziswa ekukhiqizeni izinto ezihambisana nemvelo njenge-bio-based succinic acid, ethatha indawo yemikhiqizo yendabuko esekelwe ku-petroleum. Lokhu kushintshela ekuzinzeni kulindeleke ukuthi kuqhubeke nokukhulisa isidingo se-maleic anhydride eminyakeni ezayo.
Isifunda sase-Asia Pacific singumthengi omkhulu kunawo wonke we-maleic anhydride, kanti i-China ne-India ihola lesi sidingo. Ukuthuthuka ngokushesha kwezimboni kanye nokukhula kwamadolobha kulawa mazwe kuye kwabhebhethekisa isidingo se-maleic anhydride ekusetshenzisweni okuhlukahlukene. Ngaphezu kwalokho, imikhakha yezimoto neyokwakha ekhulayo esifundeni kulindeleke ukuthi iqhubeke nokushayela isidingo se-maleic anhydride.
Ngasohlangothini lokunikezela, imakethe ye-maleic anhydride ibhekene nezinselelo ezithile. Ukuntengantenga kwezintengo zempahla yokusetshenziswa, ikakhulukazi i-butane ne-benzene, kube nomthelela ezindlekweni zokukhiqiza zabakhiqizi be-anhydride besilisa. Ukwengeza, imithetho eqinile kanye nokukhathazeka kwemvelo okuhlobene nokukhiqizwa kwe-anhydride ye-maleic kwengeze ubunzima nezindleko zokukhiqiza.
Uma sibheka phambili ku-2024, imakethe ye-anhydride ye-maleic ibikezelwa ukuthi izofakaza ukukhula okuqhubekayo. Isidingo esikhulayo sezinto ezisimeme, okuhambisana nezimboni ezikhulayo zokwakha nezezimoto, kulindeleke ukuthi ziqhube imakethe. Isifunda sase-Asia Pacific kulindeleke ukuthi siqhubeke siwumthengi obalulekile we-maleic anhydride, kanti i-China ne-India zihola phambili isidingo.
Sengiphetha, imakethe ye-maleic anhydride ilungele ukukhula ngo-2024, iqhutshwa yisidingo sezinto ezisimeme kanye nokukhula kwezimboni ezibalulekile zabasebenzisi. Nokho, izinselele ezihlobene namanani entengo yezinto ezingavuthiwe kanye nobunzima bokukhiqiza zisekhona. Ababambiqhaza emakethe ye-maleic anhydride badinga ukubhekisisa lokhu kuthuthukiswa ukuze bazulazule esimweni semakethe esishintshashintsha njalo.
