Pyromellitic Dianhydride Faatasi ai ma CAS 89-32-7
O le pyromellitic dianhydride (faʻapuʻupuʻu e pei o le PMDA), lea e masani ona faʻaaogaina mo le tuʻufaʻatasia o le polyimide, ona o le polyimide e sili ona maualuga le vevela o le vevela, faʻamaʻi ma le alkali, sili ona lelei Ona o ana mea faʻainisinia, mea eletise ma tulaga mautu, e lautele. faʻaaogaina i fanua faʻatekonolosi maualuga e pei o vaalele, aerospace, microelectronics ma atomic malosi, o loʻo i ai manaoga faʻapitoa i meafaitino.

Pyromellitic dianhydride (PMDA) ose mea mata'utia taua i le alamanuia synthesis organic, fa'apea fo'i ma mea fa'avae mo le atina'eina o mea fou vaila'au ma mea tau vaila'au fa'aopoopo maualuga. E masani ona faʻaaogaina mo le gaosiga o polyimide monomers, ma e mafai foi ona faʻaaogaina e fai ma sui Curing mo le epoxy resin ma le soʻotaga fesoʻotaʻiga mo polyester resin, faʻaaogaina i le gaosiga o le phthalocyanine lanu lanumoana ma nisi mea taua, ma isi, ma e iai. le tele o fa'aoga. Pyromellitic dianhydride, lea e lauiloa foi o le homoanhydride, ei ai se fausaga mole mole faapitoa ma e mafai ona faʻaaogaina e gaosia ai mea e faʻafefe ai le vevela, faʻafefe eletise ma vailaʻau faʻamalosi, lea e sili ona taua le faʻaaogaina o se monolayer o polyimide. E faʻapipiʻiina i le diamine manogi e maua ai le polyimide plastic, ae o le mama o le pyromellitic dianhydride e maualuga tele, lea e manaʻomia e sili atu i le 99%.
