Waa maxay Pyromeltic Dianhydride oo leh CAS 89-32-7?

Pyromellitic dianhydride (oo loo soo gaabiyo PMDA), kaas oo inta badan loo isticmaalo isku-darka polyimide, sababtoo ah polyimide wuxuu leeyahay iska caabin kulayl aad u sarreeya, iska caabin aashito iyo alkali ah, aad u fiican Sababtoo ah sifooyinkiisa farsamada, sifooyinka korontada iyo xasilloonida cabbirka, waxaa si weyn loogu isticmaalaa meelaha tiknoolajiyada sare sida duulista hawada, hawada sare, microelectronics iyo tamarta atomiga, kuwaas oo leh shuruudo adag oo ku saabsan sifooyinka agabka.

Codsiga

Pyromellitic dianhydride (PMDA) waa walax ceeriin ah oo muhiim u ah warshadaha isku-darka dabiiciga ah, iyo sidoo kale walax ceeriin ah oo aasaasi ah oo loogu talagalay horumarinta agabyada kiimikada cusub iyo alaabada kiimikada ee qiimaha sare leh. Waxaa inta badan loo isticmaalaa soo saarista monomers-ka polyimide, waxaana sidoo kale loo isticmaali karaa sidii wakiil bogsiin ah oo loogu talagalay epoxy resin iyo wakiilka isku-xidhka ee resin polyester, oo loo isticmaalo soo saarista phthalocyanine buluug dheeha iyo qaar ka mid ah waxyaabaha muhiimka ah, iwm., waxayna leedahay isticmaalyo kala duwan. Pyromellitic dianhydride, oo sidoo kale loo yaqaan homoanhydride, waxay leedahay qaab-dhismeed gaar ah oo molecular ah waxaana loo isticmaali karaa in lagu soo saaro agab leh iska caabbinta kulaylka, dahaarka korontada iyo iska caabbinta kiimikada, kuwaas oo isticmaalka ugu muhiimsan uu yahay hal lakab oo polyimide ah. Waxaa lagu sameeyay diamine aromatic si loo helo balaastikada polyimide, laakiin daahirnimada pyromellitic dianhydride aad ayay u sarreysaa, taas oo u baahan inay ka badan tahay 99%.
