Pyromellitic Dianhydride oo leh CAS 89-32-7
Dianhydride pyromellitic (oo loo soo gaabiyo PMDA), oo inta badan loo isticmaalo isku dhafka polyimide, sababtoo ah polyimide waxay leedahay iska caabin kulayl aad u sarreeya, caabbinta aashitada iyo alkali, aad u fiican Sababtoo ah sifooyinka farsamada, guryaha korantada iyo xasiloonida cabbirka, waa mid aad u ballaaran. loo isticmaalo meelaha teknoolajiyada sare sida duulista, hawada sare, microelectronics iyo tamarta atomikada, kuwaas oo leh shuruudo adag oo ku saabsan sifooyinka alaabta.

Pyromellitic dianhydride (PMDA) waa walxo muhiim ah oo ceeriin ah oo ku jira warshadaha isku-dhafka dabiiciga ah, iyo sidoo kale walxo ceeriin ah oo aasaasi ah oo loogu talagalay horumarinta walxaha kiimikaad ee cusub iyo alaabada kiimikaad ee qiimaha sare leh. Waxaa inta badan loo isticmaalaa soo saarista monomers polyimide ah, waxaana sidoo kale loo isticmaali karaa sida wakiilka Curing ee resin epoxy iyo wakiilka iskutallaabta ee xabagta polyesterka, oo loo isticmaalo soo saarista dheeha buluugga ah ee phthalocyanine iyo qaar ka mid ah derivatives muhiim ah, iwm. tiro balaadhan oo ah isticmaalka. Pyromellitic dianhydride, oo sidoo kale loo yaqaano homoanhydride, waxay leedahay qaab dhismeed gaar ah waxaana loo isticmaali karaa in lagu soo saaro walxaha leh caabbinta kulaylka, korantada korantada iyo caabbinta kiimikada, kuwaas oo isticmaalka ugu muhiimsani yahay monolayer of polyimide. Waxaa lagu farsameeyaa diamine caraf udgoon si loo helo caag polyimide ah, laakiin nadiifinta pyromellitic dianhydride waa mid aad u sarreeya, taas oo u baahan in ka badan 99%.
