Inombolo yeCas: 89-32-7 PMDA Pyromellitic dianhydride
Intshayelelo emfutshane
Iimveliso ezicocekileyo zePyromellitic dianhydride (PMDA) zimhlophe okanye zityheli kancinci. Zivezwa emoyeni omanzi ziya kutsala ngokukhawuleza umswakama ovela emoyeni kwaye zifakwe kwi-hydrolyzed kwi-Pyromellitic Acid. Zinyibilikiswe kwi-dimethyl sulfoxide, i-dimethylformamide, i-acetone kunye nezinye izinyibilikisi zendalo, azinyibiliki kwi-ether, i-chloroform kunye ne-benzene. Zisetyenziswa kakhulu njengezinto eziluhlaza ze-polyimide, kunye ne-arhente yokudibanisa ukwenza i-epoxy curing agent kunye nokupheliswa kwe-polyester resin.
I-Pyromellitic acid (PMA), ekwaziwa ngokuba yi-1,2,4,5-benzenetetracarboxylicacid, emhlophe ukuya kwetyheli njengekristale engumququ, isetyenziswa kakhulu ekwenziweni kwe-polyimide, i-octyl pyromelliate, njl.njl., yeyona nto iphambili ekuvelisweni kwe-matting curing agent.
