Maleic anhydridendi mankhwala osinthika omwe apeza ntchito zambiri m'mafakitale osiyanasiyana. Zake zapadera ndi reactivity zimapangitsa kukhala chofunika popanga zinthu zambiri. Kuchokera ku ma polima kupita ku mankhwala, maleic anhydride amatenga gawo lofunikira pakupititsa patsogolo magwiridwe antchito ndi magwiridwe antchito azinthu zosiyanasiyana.
Chimodzi mwazinthu zomwe zimagwiritsidwa ntchito kwambiri ndi maleic anhydride ndikupanga unsaturated polyester resins. Ma resinswa amagwiritsidwa ntchito kwambiri popanga mapulasitiki olimba a fiberglass, zida zamagalimoto, ndi ntchito zam'madzi. Kuthekera kwa maleic anhydride kukhala copolymerization ndi styrene kumabweretsa ma resin okhala ndi mphamvu, kulimba, komanso kukana dzimbiri.
Kuphatikiza pa ntchito yake yopanga polima, maleic anhydride imagwiritsidwanso ntchito popanga mankhwala aulimi. Imagwira ntchito ngati chomangira chopangira mankhwala ophera udzu, mankhwala ophera tizilombo, ndi fungicides, zomwe zimathandizira kuteteza mbewu komanso kukulitsa zokolola zaulimi.
Kuphatikiza apo, maleic anhydride ndi gawo lofunikira kwambiri popanga ma polima osungunuka m'madzi, omwe amapezeka m'mafakitale osiyanasiyana, kuphatikiza zomatira, zokutira, ndi zinthu zosamalira anthu. Ma polima awa amapereka zabwino monga kumamatira kwabwino, mawonekedwe opangira mafilimu, komanso kuwongolera ma rheological, kuwapangitsa kukhala ofunikira pamapangidwe osiyanasiyana.
Makampani opanga mankhwala amapindulanso ndi kugwiritsa ntchito maleic anhydride popanga mankhwala apakatikati ndi njira zoperekera mankhwala. Magulu ake ochitanso komanso magwiridwe antchito amathandizira kusinthidwa kwa mamolekyu a mankhwala, zomwe zimapangitsa kuti pakhale kusungunuka, bioavailability, ndi kuperekera kolunjika.
Kuphatikiza apo, maleic anhydride amagwiritsidwa ntchito popanga zida zoyezera mapepala, zomwe zimapangitsa mphamvu komanso kusindikizidwa kwazinthu zamapepala. Kukhoza kwake kupanga ma complexes okhazikika okhala ndi mitundu yosiyanasiyana kumapangitsa kukhala chowonjezera chofunikira pakupanga mapepala.
Pomaliza, kusinthasintha kwa maleic anhydride kumawonekera m'magwiritsidwe ake ambiri m'mafakitale. Udindo wake pakupanga ma polima, ulimi, chisamaliro chamunthu, mankhwala, ndi kupanga mapepala zikuwonetsa kufunikira kwake monga chomangira chofunikira pakupanga zida ndi zinthu zatsopano. Pamene kafukufuku ndi luso lamakono likupitirirabe patsogolo, kuthekera kwa maleic anhydride kuti athandizire ku ntchito zatsopano ndi zowongoka zimakhalabe zolimbikitsa.
