Maleic Anhydride: A Vevietɔ Organic Chemical Raw Material Ʋuʋu Ŋgɔyiyi le Akpa Geɖewo Me
Dɔwɔwɔ ƒe Agble Gãwo
Le atikewɔƒewo la, maleic anhydride nye nu vevi aɖe si wotsɔ wɔa unsaturated polyester resins (UPR). Mɔ̃ɖaŋununya nyui aɖe le aŋɔ siawo ŋu, womete ŋu nɔa te ɖe atikewo nu, eye womete ŋu nɔa te ɖe yame ƒe nɔnɔme nu o eye wozãa wo geɖe le aŋe siwo wotsɔ glass fiber reinforced plastic (GFRP), abe tɔdziʋuwo, ʋuwo ƒe akpa aɖewo, kple yaƒoƒomɔ̃ ƒe asikewo ene wɔwɔ me. Tsɔ kpe ɖe eŋu la, woate ŋu azã maleic anhydride atsɔ awɔ alkyd-resin siwo klẽna nyuie eye wonɔa anyi didina eye wozãa wo geɖe le nusiwo wotsɔ blaa nu kple nuŋlɔtsi dɔwɔƒewo.
Le aŋedɔwɔƒewo la, wozãa maleic anhydride tsɔ wɔa aŋe siwo ŋu wotrɔ asi le kple maleic anhydride. To copolymerizing kple monomer vovovowo me la, maleic anhydride ate ŋu ana plastic ƒe nɔnɔmewo nanyo ɖe edzi, abe dzoxɔxɔ ƒe tsitretsitsi kple mɔ̃ ƒe ŋusẽ dzi ɖeɖe kpɔtɔ ene. Le kpɔɖeŋu me, maleic anhydride grafted polystyrene, si wotsɔ styrene wɔ ɖekae la, te ŋu nɔa te ɖe dzoxɔxɔ nu nyuie eye wòte ŋu wɔa mɔ̃ɖaŋununya nyuie eye wozãnɛ geɖe le elektrɔnikmɔ̃wo kple ʋuwɔƒewo.
Le rababadɔwɔƒewo la, wozãa maleic anhydride tsɔ wɔa rababa siwo wotsɔ kpena ɖe eŋu. Ate ŋu awɔ nu kple rababa awɔ xɔtunu siwo wotsɔ ƒo ƒui, si ana dzoxɔxɔ ƒe tsitretsitsi kple rababa ƒe vuvu nanyo ɖe edzi. Wozãa maleic anhydride hã tsɔ wɔa rababa ƒe vulcanizing agents kple nusi tsia tsitsi nu, si wɔnɛ be rababa ƒe dɔwɔwɔ ƒe agbenɔƒe didi ɖe edzi.
Le ʋeʋẽ lilili kple atikewɔƒewo la, wozãa maleic anhydride abe domenɔla ene le lãmenugbagbeviwo ƒe wɔwɔme me. Woate ŋu azãe atsɔ awɔ ʋeʋẽ lilili vovovowo, abe diethyl maleate, si wozãna geɖe le ami ʋeʋĩwo kple atsyɔ̃ɖonuwo me ene. Tsɔ kpe ɖe eŋu la, woate ŋu azã maleic anhydride atsɔ awɔ atikewo ƒe domedomenuwo, abe maleic anhydride ƒe nusiwo woɖe tso eme ene, hena dɔlékuiwutikewo kple dzitodzito me dɔlélewo wɔwɔ.
Le tsi ŋudɔwɔwɔ me la, wozãa maleic anhydride tsɔ wɔa tsi ŋuti atikewo. Ate ŋu awɔ nu kple calcium kple magnesium ions siwo le tsi me awɔ tsi si me mekɔ o, si ana tsi ƒe sesẽ dzi naɖe akpɔtɔ. Woateŋu azã maleic anhydride hã atsɔ awɔ nusiwo xea mɔ na xɔxlɔ̃ kple nusiwo xea mɔ na ʋuʋudedi be woaxe mɔ ɖe xɔxlɔ̃ kple ʋuʋudedi nu le tsi ƒe ɖoɖowo me.
Togbɔ be wozãnɛ le mɔ vovovowo nu hã la, maleic anhydride nye esi me aɖi le eye wògblẽa nu le ame ŋu, eye ezazã kple edzadzraɖo bia be woakpɔ dedienɔnɔ ta vevie. Maleic anhydride xɔa tsi bɔbɔe le teƒe siwo fa miamiamia, eyata ehiã be woadzrae ɖo ɖe nugoe si wotu nu ɖo me. Tsɔ kpe ɖe eŋu la, maleic anhydride ƒe tsiwo gblẽna vie, eye ele be woado ametakpɔnu siwo sɔ le wo zazã me be woagaka ŋutigbalẽ kple ŋkuwo o. Le dɔwɔƒewo ƒe nuwɔwɔ me la, zi geɖe la, maleic anhydride zazã dzɔna le ɖoɖo siwo wotu me be woaɖe ŋusẽkpɔɖeamedzi ɖe nutome dzi dzi akpɔtɔ.
