Hoʻohana

Hiki ke hoʻohanaʻiaʻo Pyromellitic dianhydride no ka hanaʻana me ka hana polyimide, e hoʻohanaʻia e like me keʻano o keʻano o ke aniani. Hoʻohanaʻia ia e hana i nā mea kūʻai aku epinxy resin a me nā mea huna,ʻo Urea formaldehyde Fyes, Etc.

ʻO Pyromellitic Dianhydridend i loaʻa i nā mea nui he nui o nā noi. Ua hoʻohana nuiʻiaʻo PMDA ma keʻano he luna curing no ka epoxy resin, kahi mea e pono ai no ka polyester e resin. ʻO kēia kahi meaʻenehana kiʻekiʻe e hiki ke hoʻomau mauʻia no ka manawa lōʻihi ma 2600c.

ʻO nā mea nui nui i hoʻohanaʻia no ka hanaʻana i ka hana me nā kiʻi uila o kaʻenehana o ka mīkini a me nā kiʻiʻoniʻoni Hiki ke hoʻohanaʻia e like me ka mea hana synthetic stew hou no ka epoxy resin curing culing, stabilizer, a dye, etc

Hiki ke hoʻohanaʻiaʻo Pyromellitic Dianhydride e hana i ka resin resin consulari kiʻekiʻe, a me ka cursitit curtich costical resin curnity Hoʻohanaʻia ia e hana i ka phthaloyanane uliuli dye, etc
