Maleic anhydridendi mankhwala ofunikira apakati omwe amagwiritsidwa ntchito popanga zinthu zosiyanasiyana monga unsaturated polyester resins, zokutira, zomatira, ndi zowonjezera mafuta. Msika wapadziko lonse wa maleic anhydride wakhala ukukulirakulira m'zaka zaposachedwa, ndipo izi zikuyembekezeka kupitiliza mpaka 2024. Mubulogu iyi, tifufuza nkhani zaposachedwa zamsika ndi zomwe zikuchitika kuzungulira maleic anhydride.
Kufunika kwa maleic anhydride kumayendetsedwa ndi zinthu zingapo zofunika. Kukula kwamakampani omanga padziko lonse lapansi ndikothandiza kwambiri, chifukwa maleic anhydride amagwiritsidwa ntchito kwambiri popanga zida zomangira monga fiberglass, mapaipi, ndi akasinja. Kuphatikiza apo, kufunikira kwazinthu zopepuka komanso zolimba m'mafakitale amagalimoto ndi oyendetsa ndege kwadzetsanso kukwera kwa kugwiritsa ntchito maleic anhydride.
Chimodzi mwazinthu zomwe zimayendetsa msika wa maleic anhydride ndikukula kwazinthu zokhazikika komanso zokomera chilengedwe. Maleic anhydride amagwiritsidwa ntchito popanga zinthu zomwe sizigwirizana ndi chilengedwe monga bio-based succinic acid, zomwe zimalowa m'malo mwazinthu zachikhalidwe zamafuta. Kusinthaku kwa kukhazikika kukuyembekezeka kukulitsa kufunikira kwa maleic anhydride m'zaka zikubwerazi.
Dera la Asia Pacific ndilomwe amagwiritsa ntchito kwambiri maleic anhydride, China ndi India akutsogolera pakufunika. Kukula kwachangu komanso kukula kwamatauni m'maikowa kwalimbikitsa kufunikira kwa maleic anhydride pantchito zosiyanasiyana. Kuphatikiza apo, magawo omwe akuchulukirachulukira amagalimoto ndi zomangamanga m'derali akuyembekezeka kupitiliza kuyendetsa kufunikira kwa maleic anhydride.
Pambali yothandizira, msika wa maleic anhydride ukukumana ndi zovuta zina. Kusasinthika kwamitengo ya zinthu zopangira, makamaka za butane ndi benzene, kwasokoneza mtengo wopanga opanga maleic anhydride. Kuphatikiza apo, malamulo okhwima ndi zovuta zachilengedwe zokhudzana ndi kupanga maleic anhydride zawonjezera zovuta komanso mtengo wake.
Kuyang'ana kutsogolo kwa 2024, msika wa maleic anhydride ukuyembekezeka kuchitira umboni kukula kosasunthika. Kufunika kowonjezereka kwa zida zokhazikika, kuphatikiza kukwera kwa zomangamanga ndi mafakitale amagalimoto, kukuyembekezeka kuyendetsa msika. Dera la Asia Pacific likuyembekezeka kukhalabe ogula kwambiri a maleic anhydride, pomwe China ndi India zikutsogolera pakufunika.
Pomaliza, msika wa maleic anhydride watsala pang'ono kukula mu 2024, motsogozedwa ndi kufunikira kwa zida zokhazikika komanso kukula kwa mafakitale ogwiritsira ntchito. Komabe, zovuta zokhudzana ndi mitengo yazinthu zopangira komanso zovuta zopanga zimakhalabe. Omwe ali mumsika wa maleic anhydride akuyenera kuyang'anitsitsa zomwe zikuchitika kuti ayendetse msika womwe ukukula.
