Pyromellitic Dianhydride CAS89-32-7/PMDA

Kugwiritsa ntchito

Pyromellitic Dianhydride itha kugwiritsidwa ntchito popanga utomoni wa polyimide, womwe umagwiritsidwa ntchito ngati zopangira zopangira utoto wamagetsi osamva kutentha kwambiri.Amagwiritsidwanso ntchito popanga ma epoxy resin kuchiritsa othandizira ndi ma plasticizer, urea formaldehyde resin stabilizers, utoto wa buluu wa phthalocyanine, zoletsa corrosion, zomangira pompopompo, ma toner ojambula pakompyuta, ndi zina zambiri.

Pyromellitic Dianhydridendi zotumphukira zake zimakhala ndi ntchito zambiri.PMDA amagwiritsidwa ntchito makamaka ngati mankhwala a epoxy resin, zopangira za polyimide, ndi crosslinking agent ya polyester resin kupanga homopolymer polyetherimine resin.Ichi ndi zinthu zaumisiri zotentha kwambiri zomwe zitha kugwiritsidwa ntchito mosalekeza kwa nthawi yayitali pa 2600C.

Zopangira zazikulu zomwe zimagwiritsidwa ntchito popanga mapulasitiki osagwirizana ndi kutentha kwa polyimide ndi mafilimu otchinjiriza;Angagwiritsidwe ntchito ngati kupanga zopangira kwa epoxy utomoni kuchiritsa wothandizira, stabilizer, ndi utoto, etc.

Pyromellitic Dianhydride angagwiritsidwe ntchito kupanga polyimide utomoni, mkulu kutentha zosagwira magetsi kutchinjiriza utoto, PVC plasticizer, kupanga utomoni crosslinking wothandizira, ndi epoxy utomoni kuchiritsa wothandizila.Amagwiritsidwanso ntchito kupanga utoto wa buluu wa phthalocyanine, etc
