Maleic Anhydride (MA) (CAS: 108-31-6) inonzi acid anhydride ye maleic acid, kunhuhwirira kwakasimba kwekukurudzira.Maleic anhydride zvechokwadi imorekuru rinoshamisa nekuti ine marudzi maviri emakemikari anoshanda achiita kuti ive yakasarudzika mukugadzirwa kwemakemikari nemashandisirwo.
Maleic Anhydride ikemikari inoshanda yakawanda yepakati nekushandisa mundima dzinoverengeka dzeindasitiri yemakemikari.Kunyanya kushandiswa kwayo kwekupedzisira kwakafanana nekudyisa mukugadzira unsaturated polyester resins (UPR).Aya maresheni anoshandiswa zvese mugirazi-yakasimbiswa uye mune isina kusimbiswa maapplication.Iyo UPR yekupedzisira inoshandisa inosanganisira kuwanda kwekushandisa mukuvaka, mumakungwa uye emotokari maindasitiri.
Mukugadzirwa kwepolyester resins, fumaric acid, mishonga yekurima tupukanana, uye alkyl resins.
Mukuwedzera, Maleic Anhydride inogonawo kushandiswa seyakasvibiswa mukugadzirwa kwe1,4-butanediol (BDO), gamma-butyrolactone uye tetrahydrofuran (THF).Zvakakosha kuratidza kuti BDO ndeimwe yemakemikari ari kukurumidza kukura pasi rose mumakore apfuura.
Maleic Anhydride is heterocyclic compound inoshandiswa mukugadzira unsaturated polyester resins.Maleic Anhydride ine huwandu hwakawanda hwemamwe maapplication;inoshandiswa mukugadzira tensides, zvipembenene, mishonga yesora uye fungicides.
Kufema kunokonzera kukosora, kuhotsira, kushatirwa pahuro.Kubata ganda kunokonzera kushatirwa uye kutsvuka.Mhepo inokonzera kutsamwa kukuru kwemaziso;photophobia uye maonero maviri anogona kuitika.
