I-Maleic Anhydride (MA) (i-CAS: 108-31-6) i-acid anhydride ye-maleic acid, iphunga elinamandla elishukumisayo.I-anhydride ye-Maleic iyi-molecule ephawulekayo ngoba inezinhlobo ezimbili zokusebenza kwamakhemikhali okwenza isebenziseke ngokukhethekile ekuhlanganiseni amakhemikhali nasekusetshenzisweni kwayo.
I-Maleic Anhydride iyikhemikhali esebenza ngezindlela eziningi futhi isetshenziswa emikhakheni eminingana yomkhakha wamakhemikhali.Ukusetshenziswa kwayo okukhulu kokugcina kufana ne-feedstock ekukhiqizeni ama-unsaturated polyester resins (UPR).Lawa ma-resin asetshenziswa kokubili ku-glass-reinforced kanye nezinhlelo zokusebenza ezingaqinisiwe.Ukusetshenziswa kokuphela kwe-UPR kufaka phakathi izinhlelo zokusebenza eziningi zokwakha, izimboni zasolwandle nezezimoto.
Ekwenzeni ama-polyester resins, i-fumaric acid, izibulala-zinambuzane zezolimo, nama-alkyl resins.
Ngaphezu kwalokho, i-Maleic Anhydride ingasetshenziswa futhi njengento eluhlaza ekukhiqizeni i-1,4-butanediol (BDO), i-gamma-butyrolactone ne-tetrahydrofuran (THF).Kubalulekile ukugqamisa ukuthi i-BDO ingelinye lamakhemikhali akhula ngokushesha emhlabeni eminyakeni edlule.
I-Maleic Anhydride iyinhlanganisela ye-heterocyclic esetshenziselwa ukwakhiwa kwama-polyester resins angasetshenzisiwe.I-Maleic Anhydride inohlu olubanzi lwezinye izinhlelo zokusebenza;isetshenziswa kuma-synthetic tensides, ama-insecticide, ama-herbicides nama-fungicides.
Ukuhogela umoya kubangela ukukhwehlela, ukuthimula, ukucasuka komphimbo.Ukuthintana kwesikhumba kubangela ukucasuka nokuba bomvu.Ama-vapor abangela ukucasuka okukhulu kwamehlo;i-photophobia kanye nombono ophindwe kabili kungenzeka.
I-UN2215 Maleic Anhydride, isigaba seHazard: 8;Amalebula: 8-Ebolayo.I-Maleic Anhydride ithengiswa futhi ihanjiswa ngendlela eqinile nencibilikile.I-Maleic Anhydride encibilikisiwe ithuthwa emazingeni okushisa asukela ku-60 kuya ku-80°C ngeziqukathi zamathangi ezivaleleke kahle noma amathangi omgwaqo anikezwe izinto zokushisisa.Ngendlela eqinile, ingathuthwa njengama-pastille, avame ukupakishwa ezikhwameni ze-polyethylene ezingama-25 kg futhi zihanjiswe nge-rail tanker noma ngeloli.
Izinzile.Okuvuthayo.Akuhambisani namanzi, ama-oxidizing aqinile, izinsimbi ze-alkali, izisekelo eziqinile, ama-amine, izinsimbi ezivame kakhulu, ama-polymerization catalyst nama-accelerator.
