suma:
Mumunda wezvigadzirwa zvepamusoro,pyromellitic dianhydride(PMDA) yakabudirira sechinhu chakakosha mukugadzira kupisa-resistant polyimide resins, mafirimu uye machira.Nekudzikama kwayo kwemafuta uye kuita kwakasiyana-siyana, PMDA yave sarudzo yekutanga kune akawanda epamusoro-kuita maapplication.Mune ino blog, tinoongorora hukuru hwekugona kwePMDA uye basa ravo mukushandura maindasitiri akasiyana.
Kusagadzikana Kupisa Kupokana:
PMDA ine yakanakisa kupisa kupisa uye yakanakira mbishi zvinhu zvekugadzira polyimide mafirimu.Aya mafirimu anoshandiswa zvakanyanya mumabhodhi anochinjika akadhindwa edunhu, tepi otomatiki bonding uye magnet waya insulation.Nekubatanidza PMDA, zvinhu izvi zvinogona kumira kutonhora kwakanyanya pasina kupira kuvimbika kwavo kwechimiro.Mumashandisirwo apo kupisa kwemafuta kwakakosha, PMDA-based polyimide mafirimu anopa unrivaled performance.
Powerpack Composites:
PMDA inoitawo basa rakakosha mukugadzirwa kwepolyimide-based composite.Aya macomposites anosanganisa kupisa kwepamusoro kwepolyimide nesimba uye huremu hwezvimwe zvinhu.Nekuda kweizvozvo, maindasitiri akadai seaerospace, mota uye zvemagetsi zvinobatsirwa kubva mukugadziridzwa kwepamusoro-kushanda kwezvikamu.Kunyangwe kugadzira zvikamu zvendege kana kuvandudza kusimba kwemidziyo yemagetsi, PMDA-based composite inopa mhinduro inobudirira.
Hardener:
Pamusoro pebasa rayo mu polyimide resins, PMDA inogona zvakare kushandiswa seanorapa epoxy resins muhupfu hwekuumba.Chishandiso chinobvumira kugadzirwa kwezvinhu zvine hunyanzvi zvakaita semhete dzechisimbiso, thrust washers, spacers uye insulators.Nekuwedzera PMDA seanorapa, epoxy resin inogona kuvandudza zvinhu zvinopisa uye zvemuchina, nekudaro ichiwedzera kuita kwayo kwese uye kuwedzera huwandu hwayo hwekushandisa.
Innovation Roadmap:
Izvo zvakanakisa zvimiro zvePMDA zvinoita kuti ive chinhu chakakosha mukutsvaga hunyanzvi.Maindasitiri anovimba nekugona kwawo kwakasiyana kwekumira tembiricha yakakwira kuti ave nechokwadi chekuchengetedza uye kuvimbika kwezvigadzirwa zvavo.Nekusundidzira miganhu yekupisa kwekupisa, PMDAs inovhura mikana mitsva yekufambira mberi mune zvemagetsi, aerospace, uye mamwe minda uko kurongeka uye kuvimbika kwakakosha.
mukupedzisa:
Pyromellitic dianhydride (PMDA) ishanduko chaiyo yemutambo mumunda wezvigadzirwa zvepamberi.Iyo yakanakisa kupisa kupisa uye kuita kwakasiyana-siyana kunoita kuti ive chinhu chakakosha mukugadzirwa kwepolyimide resins, mafirimu uye macomposites.Sezvo maindasitiri achivavarira hunyanzvi uye kuvimbika, PMDA inopa hwaro hunodiwa kusundira miganhu yekupisa kupisa.Tiine PMDA pachitsigiro, tinogona kutarisira kuona kufambira mberi kwepasi mukushanda kwepamusoro-soro, kuve nechokwadi chemhando yepamusoro uye kuchengetedzeka kwemakore anotevera.
